Section 1 of act July 19, 1952, ch. 950, 66 Stat. 792, provided in part that this title may be cited as “Title 35, United States Code, section —.”

Section 3 of act July 19, 1952, ch. 950, 66 Stat. 815, provided that: “If any provision of Title 35, as enacted by section 1 hereof, is declared unconstitutional or is held invalid, the validity of the remainder of this title shall not be affected.”

Section 4 of act July 19, 1952, ch. 950, 66 Stat. 815, provided that:

“(a) This Act [enacting this title] shall take effect on January 1, 1953 and shall apply to all applications for patent filed on or after such date and to all patents granted on such applications. It shall apply to further proceedings on applications pending on such date and to patents granted on such applications except as otherwise provided. It shall apply to unexpired patents granted prior to such date except as otherwise provided.

“(b) Section 102(d) of Title 35, as enacted by section 1 hereof, shall not apply to existing patents and pending applications, but the law previously in effect, namely the first paragraph of R. S. 4887 [first paragraph of section 32 of former Title 35], shall apply to such patents and applications.

“(c) Section 119, second paragraph, of Title 35 as enacted by section 1 hereof shall not apply to existing patents.

“(d) The period of one year specified in section 102(b) of Title 35 as enacted by section 1 hereof shall not apply in the case of applications filed before August 5, 1940, and patents granted on such applications, and with respect to such applications and patents, said period is two years instead of one year.

“(e) Nothing contained in Title 35, as enacted by section 1 hereof, shall operate to nullify any judicial finding prior to the effective date of this Act on the validity of any patent by a court of competent jurisdiction.

“(f) Nothing in Title 35, as enacted by section 1 hereof, shall affect any provision of the Atomic Energy Act of 1946 (Aug. 1, 1946, ch. 724, 60 Stat. 755) [§2011 et seq. of Title 42, The Public Health and Welfare].

“(g) The period of one year specified in section 4 of Title 35 as enacted by section 1 hereof shall not apply in the case of applications filed before the effective date of this Act.

“(h) The repeal of sections 1–9, 11, 12 of the Act of Congress approved February 1, 1952 (ch. 4, 66 Stat. 3) [sections 151 to 159 of former Title 35], shall not affect any rights or liabilities existing on the date of approval of this Act [July 19, 1952]. An order of secrecy issued under or in effect under the repealed Act and in effect on the date of approval of this Act, shall be considered as issued under this Act, and any claims arising under the repealed Act or subject to presentation and determination pursuant thereto and unsettled as of the effective date of this Act, may be presented and determined pursuant to the provisions of this Act [this title].”

Section 5 of act July 19, 1952, ch. 950, 66 Stat. 815, repealed the sections or parts of sections of the Revised Statutes or Statutes at Large codified in this Act with the proviso that “Any rights or liabilities now existing under such sections or parts thereof shall not be affected by this repeal.”

This title is referred to in title 11 section 101; title 15 sections 278n, 3703; title 17 section 912; title 42 section 12002.


1991—Pub. L. 102–204, §5(d)(2)(D), Dec. 10, 1991, 105 Stat. 1640, substituted “before” for “Before the” in chapter 3 heading and inserted “; Funding; Search Systems” after “Fees” in chapter 4 heading.

1975—Pub. L. 93–596, §1, Jan. 2, 1975, 88 Stat. 1949, substituted “PATENT AND TRADEMARK OFFICE” for “PATENT OFFICE” in part heading and in headings for chapters 2 and 3.


1984—Pub. L. 98–622, title II, §201(b), Nov. 8, 1984, 98 Stat. 3386, substituted “Patent Appeals and Interferences” for “Appeals” in item 7.

1972—Pub. L. 92–310, title II, §208(b), June 6, 1972, 86 Stat. 203, struck out item 5 “Bond of Commissioner and other officers”.

Access to facilities for study, research and illustration in the Patent and Trademark Office, see section 91 of Title 20, Education.

Audit of accounts, see section 3523 of Title 31, Money and Finance.

Constitutional provisions, see Const. Art. 1, §8, cl. 8.

Department of Commerce, jurisdiction and supervision of the Patent and Trademark Office, see section 1511 of Title 15, Commerce and Trade.

Records, books, etc., of Patent and Trademark Office, admissibility of copies as evidence, see section 1744 of Title 28, Judiciary and Judicial Procedure.

1 So in original. Probably should be capitalized.

The Patent and Trademark Office shall continue as an office in the Department of Commerce, where records, books, drawings, specifications, and other papers and things pertaining to patents and to trademark registrations shall be kept and preserved, except as otherwise provided by law.

(July 19, 1952, ch. 950, 66 Stat. 792; Jan. 2, 1975, Pub. L. 93–596, §1, 88 Stat. 1949.)

Based on Title 35, U.S.C., 1946 ed., §1 (R.S. 475 and Executive Order 4175, Mar. 17, 1925).

The word “all” is omitted from the corresponding section of the existing statute and “except as otherwise provided by law” added, since some old records are kept in the National Archives, see 44 U.S.C., 1946 ed., ch. 8A.

The word “models” has been omitted to remove emphasis on models since they are no longer generally required. They are included by the word “things.”

The phrase “and to trade-mark registrations” is added. There is no enactment corresponding to this section in the trade-mark law. The original chapter of the Revised Statutes containing this section deals with the Patent Office as such in its administration of trade-marks as well as patents. This is explicitly brought out in some of the corresponding sections of the present chapter. Changes in language are made.

1975—Pub. L. 93–596 substituted “Patent and Trademark Office” for “Patent Office”.

Section 3 of Pub. L. 93–596 provided that: “The terms ‘Patent Office’ and ‘Commissioner of Patents’ in all laws of the United States shall mean ‘Patent and Trademark Office’ and ‘Commissioner of Patents and Trademarks’, respectively.”

Amendment by Pub. L. 93–596 effective Jan. 2, 1975, see section 4 of Pub. L. 93–596, set out as a note under section 1111 of Title 15, Commerce and Trade.

Pub. L. 100–418, §9001, Aug. 23, 1988, 102 Stat. 1563, provided that: “This subtitle [subtitle A (§§9001–9007) of title IX of Pub. L. 100–418, enacting section 295 of this title, amending sections 154, 271, and 287 of this title, and enacting provisions set out as notes under section 271 of this title] may be cited as the ‘Process Patent Amendments Act of 1988’.”

Pub. L. 100–418, title IX, §9101(a), Aug. 23, 1988, 102 Stat. 1567, provided that: “This section [amending sections 184 to 186 of this title and enacting provisions set out as notes under section 184 of this title] may be cited as the ‘Patent Law Foreign Filing Amendments Act of 1988’.”

Pub. L. 98–622, §1, Nov. 8, 1984, 98 Stat. 3383, provided that: “This Act [enacting section 157 of this title, amending sections 3, 7, 41, 103, 104, 116, 120, 134, 135, 141, 145, 146, 271, 305, 351, 361, 362, 365 to 368, 371 to 373, and 376 of this title, section 1295 of Title 28, Judiciary and Judicial Procedure, and sections 2182 and 2457 of Title 42, The Public Health and Welfare, and enacting provisions set out as notes under sections 7, 41, 103, 157, and 351 of this title] may be cited as the ‘Patent Law Amendments Act of 1984’.”

Pub. L. 101–508, title X, §10102, Nov. 5, 1990, 104 Stat. 1388–392, provided that: “For the purposes of Federal law, the Patent and Trademark Office shall be considered a Federal agency. In particular, the Patent and Trademark Office shall be subject to all Federal laws pertaining to the procurement of goods and services that would apply to a Federal agency using appropriated funds, including the Federal Property and Administrative Services Act of 1949 [see Short Title note set out under section 471 of Title 40, Public Buildings, Property, and Works] and the Office of Federal Procurement Policy Act [41 U.S.C. 401 et seq.].”

The Patent and Trademark Office shall have a seal with which letters patent, certificates of trade-mark registrations, and papers issued from the Office shall be authenticated.

(July 19, 1952, ch. 950, 66 Stat. 792; Jan. 2, 1975, Pub. L. 93–596, §1, 88 Stat. 1949.)

Based on Title 35, U.S.C., 1946 ed., §3 (R.S. 478).

“Certificates of trade-mark registrations” is added, see note under section 1. Changes in language are made and the specific date eliminated.

1975—Pub. L. 93–596 substituted “Patent and Trademark Office” for “Patent Office”.

Amendment by Pub. L. 93–596 effective Jan. 2, 1975, see section 4 of Pub. L. 93–596, set out as a note under section 1111 of Title 15, Commerce and Trade.

Patents issued under seal of Patent and Trademark Office, see section 153 of this title.

(a) There shall be in the Patent and Trademark Office a Commissioner of Patents and Trademarks, a Deputy Commissioner, two Assistant Commissioners, and examiners-in-chief appointed under section 7 of this title. The Deputy Commissioner, or, in the event of a vacancy in that office, the Assistant Commissioner senior in date of appointment shall fill the office of Commissioner during a vacancy in that office until the Commissioner is appointed and takes office. The Commissioner of Patents and Trademarks, the Deputy Commissioner, and the Assistant Commissioners shall be appointed by the President, by and with the advice and consent of the Senate. The Secretary of Commerce, upon the nomination of the Commissioner, in accordance with law shall appoint all other officers and employees.

(b) The Secretary of Commerce may vest in himself the functions of the Patent and Trademark Office and its officers and employees specified in this title and may from time to time authorize their performance by any other officer or employee.

(c) The Secretary of Commerce is authorized to fix the per annum rate of basic compensation of each examiner-in-chief in the Patent and Trademark Office at not in excess of the maximum scheduled rate provided for positions in grade 17 of the General Schedule of the Classification Act of 1949, as amended.1

(d) The Commissioner of Patents and Trademarks shall be an Assistant Secretary of Commerce and shall receive compensation at the rate prescribed by law for Assistant Secretaries of Commerce.

(e) The members of the Trademark Trial and Appeal Board of the Patent and Trademark Office shall each be paid at a rate not to exceed the maximum rate of basic pay payable for GS–16 of the General Schedule under section 5332 of title 5.

(July 19, 1952, ch. 950, 66 Stat. 792; Sept. 6, 1958, Pub. L. 85–933, §1, 72 Stat. 1793; Sept. 23, 1959, Pub. L. 86–370, §1(a), 73 Stat. 650; Aug. 14, 1964, Pub. L. 88–426, title III, §305(26), 78 Stat. 425; Jan. 2, 1975, Pub. L. 93–596, §1, 88 Stat. 1949; Jan. 2, 1975, Pub. L. 93–601, §1, 88 Stat. 1956; Aug. 27, 1982, Pub. L. 97–247, §4, 96 Stat. 319; Oct. 25, 1982, Pub. L. 97–366, §4, 96 Stat. 1760; Nov. 8, 1984, Pub. L. 98–622, title IV, §405, 98 Stat. 3392.)

Based on Title 35, U.S.C., 1946 ed., §2 (R.S. 476, amended (1) Feb. 15, 1916, ch. 22, §1, 39 Stat. 8, (2) Feb. 14, 1927, ch. 139, §1, 44 Stat. 1098, (3) Apr. 11, 1930, ch. 132, §1, 46 Stat. 155).

The temporary designation of the assistant commissioner as Commissioner in case of a vacancy in office is added. This will eliminate complications since present applicable general statutes (5 U.S.C., 1946 ed., §7) permit a vacancy to be temporarily filled only for not more than 30 days.

Changes in language are made. “Assistant commissioners” is used in the second sentence (and elsewhere in the bill) as referring to all three assistants.

This entire title is subject to Reorganization Plan No. 5 of 1950 (64 Stat. 1263) which vests all functions of the Patent Office in the Secretary of Commerce and authorizes delegation by him. It has been found impractical to so word the various sections of the title, and a general provision has been inserted as the second paragraph of this section of the bill, leaving the wording of various sections of the title in terms of officers previously specified and to whom the functions presently stand delegated.

The Classification Act of 1949, as amended, referred to in subsec. (c), is act Oct. 28, 1949, ch. 782, 63 Stat. 954, as amended, which was repealed by Pub. L. 89–554, §8(a), Sept. 6, 1966, 80 Stat. 632, and reenacted by the first section thereof as chapter 51 (§5101 et seq.) and subchapter III (§5331 et seq.) of chapter 53 of Title 5, Government Organization and Employees.

1982—Subsec. (a). Pub. L. 97–247 struck out “not more than fifteen” after “two Assistant Commissioners, and”, and inserted “appointed under section 7 of this title” after “examiners-in-chief”.

Subsec. (d). Pub. L. 97–366 added subsec. (d).

1975—Pub. L. 93–596 substituted “Patent and Trademark Office” for “Patent Office”, and “Commissioner of Patents and Trademarks” for “Commissioner of Patents”, wherever appearing.

Subsec. (a). Pub. L. 93–601 designated first par. as subsec. (a), redesignated first assistant commissioner as a Deputy Commissioner, granted authority for appointment of not more than fifteen examiners-in-chief to Secretary of Commerce instead of the President, and struck out provision relating to performance by assistant commissioners of duties assigned by Commissioner.

Subsecs. (b), (c). Pub. L. 93–601 designated second and third pars. as subsecs. (b) and (c), respectively.

1964—Pub. L. 88–426 repealed provisions which prescribed annual rate of compensation of Commissioner.

1959—Pub. L. 86–370 authorized Secretary of Commerce to fix compensation of examiners-in-chief.

1958—Pub. L. 85–933 increased number of examiners-in-chief from nine to not more than fifteen and specified annual compensation of Commissioner.

Section 406(b) of Pub. L. 98–622 provided that: “The amendments made by sections 401, 402, and 405 of this Act [amending this section and sections 361, 366, 371, 372, and 376 of this title] shall take effect six months after the date of the enactment of this Act [Nov. 8, 1984].”

Amendment by Pub. L. 97–247 effective Aug. 27, 1982, see section 17(a) of Pub. L. 97–247, set out as a note under section 41 of this title.

Section 4(b) of Pub. L. 93–601 provided that: “This Act [amending this section and sections 7 and 151 of this title and enacting provisions set out as a note under section 151 of this title] shall be effective upon enactment [Jan. 2, 1975]. Examiners-in-chief in office on the date of enactment shall continue in office under and in accordance with their then existing appointments.”

Amendment by Pub. L. 93–596 effective Jan. 2, 1975, see section 4 of Pub. L. 93–596, set out as a note under section 1111 of Title 15, Commerce and Trade.

Amendment by Pub. L. 88–426 effective on first day of first pay period which begins on or after July 1, 1964, except to the extent provided in section 501(c) of Pub. L. 88–426, see section 501 of Pub. L. 88–426.

Section 7(b) of Pub. L. 86–370 provided that: “Sections 1 [amending this section, section 7 of this title, and provisions set out as a note below], 3 [amending sections 2205 and 2208 of former Title 5, Executive Departments and Government Officers and Employees], and 6 [amending section 1082 of former Title 5 and section 903 of Title 20, Education] of this Act shall become effective on the first day of the first pay period which begins after the date of enactment of this Act [Sept. 23, 1959].” Such section 7(b) was repealed by Pub. L. 89–554, §8(a), Sept. 6, 1966, 80 Stat. 660.

References in laws to the rates of pay for GS–16, 17, or 18, or to maximum rates of pay under the General Schedule, to be considered references to rates payable under specified sections of Title 5, Government Organization and Employees, see section 529 [title I, §101(c)(1)] of Pub. L. 101–509, set out in a note under section 5376 of Title 5.

Section 1(c) of Pub. L. 86–370 provided that: “The amendments made by this section [amending sections 1 and 7 of this title] shall not affect—

“(1) any position of examiner-in-chief or designated examiner-in-chief existing immediately prior to the effective date of this section [see Effective Date of 1959 Amendment note set out above], or

“(2) any incumbent of any such position, his appointment thereto, his rate of compensation, or his right to receive such compensation,

until appropriate action is taken under authority of such amendments.”

(July 19, 1952, ch. 950, 66 Stat. 793; Jan. 2, 1975, Pub. L. 93–596, §1, 88 Stat. 1949.)

Based on Title 35, U.S.C., 1946 ed., §4 (R.S. 480).

The language is revised and inability to apply for a patent, included in the original language, is made explicit.

The period of disability is increased to include one year after leaving the Office.

The further restriction, that no priority date earlier than one year after leaving the Office can be claimed, is added.

The one year period is made inapplicable to applications which may be pending when the revised title goes into effect by section 4(g) of the bill.

1975—Pub. L. 93–596 substituted “Patent and Trademark Office” for “Patent Office”.

Amendment by Pub. L. 93–596 effective Jan. 2, 1975, see section 4 of Pub. L. 93–596, set out as a note under section 1111 of Title 15, Commerce and Trade.

Section, act July 19, 1952, ch. 950, 66 Stat. 793, related to bond of Commissioner and other officers.

(a) The Commissioner, under the direction of the Secretary of Commerce, shall superintend or perform all duties required by law respecting the granting and issuing of patents and the registration of trademarks; shall have the authority to carry on studies, programs, or exchanges of items or services regarding domestic and international patent and trademark law or the administration of the Patent and Trademark Office, including programs to recognize, identify, assess and forecast the technology of patented inventions and their utility to industry; and shall have charge of property belonging to the Patent and Trademark Office. He may, subject to the approval of the Secretary of Commerce, establish regulations, not inconsistent with law, for the conduct of proceedings in the Patent and Trademark Office.

1991—Subsec. (a). Pub. L. 102–204 substituted “, including programs to recognize, identify, assess and forecast the technology of patented inventions and their utility to industry; and shall have” for “; and shall have”.

1982—Subsec. (a). Pub. L. 97–247, §13, substituted “, programs, or exchanges of items or services” for “and programs” before “regarding domestic”, and inserted “or the administration of the Patent and Trademark Office” after “trademark law”.

Subsec. (d). Pub. L. 97–247, §7, struck out subsec. (d) which provided that the Commissioner, under the direction of the Secretary of Commerce, could, with the concurrence of the Secretary of State, allocate funds appropriated to the Patent Office, to the Department of State for the purpose of payment of the share on the part of the United States to the working capital fund established under the Patent Cooperation Treaty and that contributions to cover the share on the part of the United States of any operating deficits of the International Bureau under the Patent Cooperation Treaty would be included in the annual budget of the Patent Office and could be transferred by the Commissioner, under the direction of the Secretary of Commerce, to the Department of State for the purpose of making payments thereof to the International Bureau.

1975—Subsecs. (a), (c). Pub. L. 93–596 substituted “Patent and Trademark Office” for “Patent Office” wherever appearing.

(July 19, 1952, ch. 950, 66 Stat. 796; Nov. 14, 1975, Pub. L. 94–131, §4, 89 Stat. 690; Dec. 12, 1980, Pub. L. 96–517, §3, 94 Stat. 3018; Aug. 27, 1982, Pub. L. 97–247, §3(g), 96 Stat. 319; Sept. 13, 1982, Pub. L. 97–258, §3(i), 96 Stat. 1065; Dec. 10, 1991, Pub. L. 102–204, §§4, 5(e), 105 Stat. 1637, 1640.)

Based on Title 35, U.S.C., 1946 ed., §79 (Mar. 6, 1920, ch. 94, §1 (part), 41 Stat. 503, 512).

Language has been changed.

Section 31 of the Trademark Act of 1946, referred to in subsec. (c), is classified to section 1113 of Title 15, Commerce and Trade.

1991—Subsec. (c). Pub. L. 102–204, §5(e), amended subsec. (c) generally. Prior to amendment, subsec. (c) read as follows: “Revenues from fees will be available to the Commissioner of Patents to carry out, to the extent provided for in appropriation Acts, the activities of the Patent and Trademark Office. Fees available to the Commissioner under section 31 of the Trademark Act of 1946, as amended (15 U.S.C. 1113), shall be used exclusively for the processing of trademark registrations and for other services and materials related to trademarks.”

Subsec. (e). Pub. L. 102–204, §4, added subsec. (e).

1982—Subsec. (b). Pub. L. 97–258 struck out “, the provisions of section 725e of title 31, United States Code, notwithstanding” after “United States”.

Subsec. (c). Pub. L. 97–247 inserted provision that fees available to the Commissioner under section 31 of the Trademark Act of 1946, as amended (15 U.S.C. 1113), be used exclusively for the processing of trademark registrations and for other services and materials related to trademarks.

1980—Pub. L. 96–517 designated existing provision relating to payment of patent fees as subsec. (a) and struck out provision that, except as provided in sections 361(b) and 376(b) of this title, the Commissioner deposit fees paid in the Treasury of the United States in such manner as directed by the Secretary of the Treasury, designated existing provision relating to return of excess amounts paid as subsec. (d), and added subsecs. (b) and (c).

1975—Pub. L. 94–131 inserted “, except as provided in sections 361(b) and 376(b) of this title,”.

Amendment by Pub. L. 97–247 effective Oct. 1, 1982, see section 17(a) of Pub. L. 97–247, set out as a note under section 41 of this title.

Amendment by Pub. L. 96–517 effective on first day of first fiscal year beginning on or after one calendar year after Dec. 12, 1980, subject to authorization of appropriation account credits from collected reexamination fees prior to the effective date, made available for payment of reexamination proceedings costs, see section 8(c) of Pub. L. 96–517, set out as a note under section 41 of this title.

Amendment by Pub. L. 94–131 effective Jan. 24, 1978, and applicable on and after that date to patent applications filed in the United States and to international applications, where applicable, see section 11 of Pub. L. 94–131, set out as an Effective Date note under section 351 of this title.

Pub. L. 100–703, title I, §102, Nov. 19, 1988, 102 Stat. 4674, provided that: “Amounts appropriated under this Act and such fees as may be collected under title 35, United States Code, and the Trademark Act of 1946 (15 U.S.C. 1051 and following) may remain available until expended.”

Similar provisions were contained in the following prior authorization act:

Pub. L. 99–607, §2, Nov. 6, 1986, 100 Stat. 3470.



1982—Pub. L. 97–256, title I, §101(6), Sept. 8, 1982, 96 Stat. 816, added item for chapter 18.

1975—Pub. L. 93–596, §1, Jan. 2, 1975, 88 Stat. 1949, substituted “Patent and Trademark Office” for “Patent Office” in heading of chapter 13.

This part is referred to in section 282 of this title.


1990—Pub. L. 101–580, §1(b), Nov. 15, 1990, 104 Stat. 2863, added item 105.

1 So in original. Does not conform to chapter heading.

When used in this title unless the context otherwise indicates—

(a) The term “invention” means invention or discovery.

(b) The term “process” means process, art or method, and includes a new use of a known process, machine, manufacture, composition of matter, or material.

(c) The terms “United States” and “this country” mean the United States of America, its territories and possessions.

(d) The word “patentee” includes not only the patentee to whom the patent was issued but also the successors in title to the patentee.

(July 19, 1952, ch. 950, 66 Stat. 797.)

Paragraph (a) is added only to avoid repetition of the phrase “invention or discovery” and its derivatives throughout the revised title. The present statutes use the phrase “invention or discovery” and derivatives.

Paragraph (b) is noted under section 101.

Paragraphs (c) and (d) are added to avoid the use of long expressions in various parts of the revised title.

Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.

(July 19, 1952, ch. 950, 66 Stat. 797.)

Based on Title 35, U.S.C., 1946 ed., §31 (R.S. 4886, amended (1) Mar. 3, 1897, ch. 391, §1, 29 Stat. 692, (2) May 23, 1930, ch. 312, §1, 46 Stat. 376, (3) Aug. 5, 1939, ch. 450, §1, 53 Stat. 1212).

The corresponding section of existing statute is split into two sections, section 101 relating to the subject matter for which patents may be obtained, and section 102 defining statutory novelty and stating other conditions for patentability.

Section 101 follows the wording of the existing statute as to the subject matter for patents, except that reference to plant patents has been omitted for incorporation in section 301 and the word “art” has been replaced by “process”, which is defined in section 100. The word “art” in the corresponding section of the existing statute has a different meaning than the same word as used in other places in the statute; it has been interpreted by the courts as being practically synonymous with process or method. “Process” has been used as its meaning is more readily grasped than “art” as interpreted, and the definition in section 100(b) makes it clear that “process or method” is meant. The remainder of the definition clarifies the status of processes or methods which involve merely the new use of a known process, machine, manufacture, composition of matter, or material; they are processes or methods under the statute and may be patented provided the conditions for patentability are satisfied.

Design patents, see section 171 et seq. of this title.

Issue of patent generally, see section 151 et seq. of this title.

Plant patents, see section 161 et seq. of this title.

A person shall be entitled to a patent unless—

(a) the invention was known or used by others in this country, or patented or described in a printed publication in this or a foreign country, before the invention thereof by the applicant for patent, or

(b) the invention was patented or described in a printed publication in this or a foreign country or in public use or on sale in this country, more than one year prior to the date of the application for patent in the United States, or

(c) he has abandoned the invention, or

(d) the invention was first patented or caused to be patented, or was the subject of an inventor's certificate, by the applicant or his legal representatives or assigns in a foreign country prior to the date of the application for patent in this country on an application for patent or inventor's certificate filed more than twelve months before the filing of the application in the United States, or

(e) the invention was described in a patent granted on an application for patent by another filed in the United States before the invention thereof by the applicant for patent, or on an international application by another who has fulfilled the requirements of paragraphs (1), (2), and (4) of section 371(c) of this title before the invention thereof by the applicant for patent, or

(f) he did not himself invent the subject matter sought to be patented, or

(g) before the applicant's invention thereof the invention was made in this country by another who had not abandoned, suppressed, or concealed it. In determining priority of invention there shall be considered not only the respective dates of conception and reduction to practice of the invention, but also the reasonable diligence of one who was first to conceive and last to reduce to practice, from a time prior to conception by the other.

(July 19, 1952, ch. 950, 66 Stat. 797; July 28, 1972, Pub. L. 92–358, §2, 86 Stat. 502; Nov. 14, 1975, Pub. L. 94–131, §5, 89 Stat. 691.)

Paragraphs (a), (b), and (c) are based on Title 35, U.S.C., 1946 ed., §31 (R.S. 4886, amended (1) Mar. 3, 1897, ch. 391, §1, 29 Stat. 692, (2) May 23, 1930, ch. 312, §1, 46 Stat. 376, (3) Aug. 5, 1939, ch. 450, §1, 53 Stat. 1212).

No change is made in these paragraphs other than that due to division into lettered paragraphs. The interpretation by the courts of paragraph (a) as being more restricted than the actual language would suggest (for example, “known” has been held to mean “publicly known”) is recognized but no change in the language is made at this time. Paragraph (a) together with section 104 contains the substance of Title 35, U.S.C., 1946 ed., §72 (R.S. 4923).

Paragraph (d) is based on Title 35, U.S.C., 1946 ed., §32, first paragraph (R.S. 4887 (first paragraph), amended (1) Mar. 3, 1897, ch. 391, §3, 29 Stat. 692, 693, (2) Mar. 3, 1903, ch. 1019, §1, 32 Stat. 1225, 1226, (3) June 19, 1936, ch. 594, 49 Stat. 1529).

The section has been changed so that the prior foreign patent is not a bar unless it was granted before the filing of the application in the United States.

Paragraph (e) is new and enacts the rule of *Milburn* v. *Davis-Bournonville,* 270 U.S. 390, by reason of which a United States patent disclosing an invention dates from the date of filing the application for the purpose of anticipating a subsequent inventor.

Paragraph (f) indicates the necessity for the inventor as the party applying for patent. Subsequent sections permit certain persons to apply in place of the inventor under special circumstances.

Paragraph (g) is derived from Title 35, U.S.C., 1946 ed., §69 (R.S. 4920, amended (1) Mar. 3, 1897, ch. 391, §2, 29 Stat. 692, (2) Aug. 5, 1939, ch. 450, §1, 53 Stat. 1212), the second defense recited in this section. This paragraph retains the present rules of law governing the determination of priority of invention.

Language relating specifically to designs is omitted for inclusion in subsequent sections.

1975—Par. (e). Pub. L. 94–131 inserted provision for nonentitlement to a patent where the invention was described in a patent granted on an international application by another who has fulfilled the requirements of pars. (1), (2), and (4) of section 371(c) of this title before the invention thereof by the applicant for patent.

1972—Subsec. (d). Pub. L. 92–358 inserted reference to inventions that were the subject of an inventors’ certificate.

Amendment by Pub. L. 94–131 effective Jan. 24, 1978, and applicable on and after that date to patent applications filed in the United States and to international applications, where applicable, see section 11 of Pub. L. 94–131, set out as an Effective Date note under section 351 of this title.

Section 3(b) of Pub. L. 92–358 provided that: “Section 2 of this Act [amending this section] shall take effect six months from the date when Articles 1 to 12 of the Paris Convention of March 20, 1883, for the Protection of Industrial Property, as revised at Stockholm, July 14, 1967, come into force with respect to the United States [Aug. 25, 1973] and shall apply to applications thereafter filed in the United States.”

Section 4 of act July 19, 1952, ch. 950, 66 Stat. 815, provided that subsection (d) of this section should not apply to existing patents and pending applications, but that the law previously in effect, namely the first paragraph of R.S. 4887 [first paragraph of section 32 of former Title 35], should apply to such patents and applications. Said paragraph of section 32 provided that:

“No person otherwise entitled thereto shall be debarred from receiving a patent for his invention or discovery, nor shall any patent be declared invalid by reason of its having been first patented or caused to be patented by the inventor or his legal representatives or assigns in a foreign country, unless the application for said foreign patent was filed more than twelve months, in cases within the provisions of section 31 of this title, and six months in cases of designs, prior to the filing of the application in this country, in which case no patent shall be granted in this country.”

Relief as to filing date of patent application or patent affected by postal situation beginning on Mar. 18, 1970, and ending on or about Mar. 30, 1970, but patents issued with earlier filing dates not effective as prior art under subsec. (e) of this section of such earlier filing dates, see note set out under section 111 of this title.

Abandonment of invention for unauthorized disclosure, see section 182 of this title.

Benefit of earlier filing date in foreign country; right of priority, see section 119 of this title.

Filing application in foreign country, see section 184 of this title.

Interferences, see section 135 of this title.

Time of prior use or publication for design patents, see section 172 of this title.

This section is referred to in sections 103, 172, 363, 375 of this title.

A patent may not be obtained though the invention is not identically disclosed or described as set forth in section 102 of this title, if the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. Patentability shall not be negatived by the manner in which the invention was made.

Subject matter developed by another person, which qualifies as prior art only under subsection (f) or (g) of section 102 of this title, shall not preclude patentability under this section where the subject matter and the claimed invention were, at the time the invention was made, owned by the same person or subject to an obligation of assignment to the same person.

(July 19, 1952, ch. 950, 66 Stat. 798; Nov. 8, 1984, Pub. L. 98–622, title I, §103, 98 Stat. 3384.)

There is no provision corresponding to the first sentence explicitly stated in the present statutes, but the refusal of patents by the Patent Office, and the holding of patents invalid by the courts, on the ground of lack of invention or lack of patentable novelty has been followed since at least as early as 1850. This paragraph is added with the view that an explicit statement in the statute may have some stabilizing effect, and also to serve as a basis for the addition at a later time of some criteria which may be worked out.

The second sentence states that patentability as to this requirement is not to be negatived by the manner in which the invention was made, that is, it is immaterial whether it resulted from long toil and experimentation or from a flash of genius.

1984—Pub. L. 98–622 inserted “Subject matter developed by another person, which qualifies as prior art only under subsection (f) or (g) of section 102 of this title, shall not preclude patentability under this section where the subject matter and the claimed invention were, at the time the invention was made, owned by the same person or subject to an obligation of assignment to the same person.”

Section 106 of Pub. L. 98–622 provided that:

“(a) Subject to subsections (b), (c), (d), and (e) of this section, the amendments made by this Act [probably should be “this title”, meaning title I of Pub. L. 98–622, enacting section 157 of this title, amending this section and sections 116, 120, 135, and 271 of this title, and enacting a provision set out as a note under section 157 of this title] shall apply to all United States patents granted before, on, or after the date of enactment of this Act [Nov. 8, 1984], and to all applications for United States patents pending on or filed after the date of enactment.

“(b) The amendments made by this Act shall not affect any final decision made by the court or the Patent and Trademark Office before the date of enactment of this Act [Nov. 8, 1984], with respect to a patent or application for patent, if no appeal from such decision is pending and the time for filing an appeal has expired.

“(c) Section 271(f) of title 35, United States Code, added by section 101 of this Act shall apply only to the supplying, or causing to be supplied, of any component or components of a patented invention after the date of enactment of this Act [Nov. 8, 1984].

“(d) No United States patent granted before the date of enactment of this Act [Nov. 8, 1984] shall abridge or affect the right of any person or his successors in business who made, purchased, or used prior to such effective date anything protected by the patent, to continue the use of, or to sell to others to be used or sold, the specific thing so made, purchased, or used, if the patent claims were invalid or otherwise unenforceable on a ground obviated by section 103 or 104 of this Act [amending this section and sections 116 and 120 of this title] and the person made, purchased, or used the specific thing in reasonable reliance on such invalidity or unenforceability. If a person reasonably relied on such invalidity or unenforceability, the court before which such matter is in question may provide for the continued manufacture, use, or sale of the thing made, purchased, or used as specified, or for the manufacture, use, or sale of which substantial preparation was made before the date of enactment of this Act, and it may also provide for the continued practice of any process practiced, or for the practice of which substantial preparation was made, prior to the date of enactment, to the extent and under such terms as the court deems equitable for the protection of investments made or business commenced before the date of enactment.

“(e) The amendments made by this Act shall not affect the right of any party in any case pending in court on the date of enactment [Nov. 8, 1984] to have their rights determined on the basis of the substantive law in effect prior to the date of enactment.”

L. 98–622, title IV, §403(a), 98 Stat. 3392; Dec. 8, 1993, Pub. L. 103–182, title III, §331, 107 Stat. 2113; Dec. 8, 1994, Pub. L. 103–465, title V, §531(a), 108 Stat. 4982.)

Pub. L. 103–465, title V, §531, Dec. 8, 1994, 108 Stat. 4982, provided that, applicable to all patent applications that are filed on or after date that is 12 months after date of entry into force of the WTO Agreement with respect to the United States [Jan. 1, 1995], with provisions relating to establishment of date of invention, this section is amended to read as follows:

(a) In General.—

(1) Proceedings.—In proceedings in the Patent and Trademark Office, in the courts, and before any other competent authority, an applicant for a patent, or a patentee, may not establish a date of invention by reference to knowledge or use thereof, or other activity with respect thereto, in a foreign country other than a NAFTA country or a WTO member country, except as provided in sections 119 and 365 of this title.

(2) Rights.—If an invention was made by a person, civil or military—

(A) while domiciled in the United States, and serving in any other country in connection with operations by or on behalf of the United States,

(B) while domiciled in a NAFTA country and serving in another country in connection with operations by or on behalf of that NAFTA country, or

(C) while domiciled in a WTO member country and serving in another country in connection with operations by or on behalf of that WTO member country,

that person shall be entitled to the same rights of priority in the United States with respect to such invention as if such invention had been made in the United States, that NAFTA country, or that WTO member country, as the case may be.

(3) Use of information.—To the extent that any information in a NAFTA country or a WTO member country concerning knowledge, use, or other activity relevant to proving or disproving a date of invention has not been made available for use in a proceeding in the Patent and Trademark Office, a court, or any other competent authority to the same extent as such information could be made available in the United States, the Commissioner, court, or such other authority shall draw appropriate inferences, or take other action permitted by statute, rule, or regulation, in favor of the party that requested the information in the proceeding.

(b) Definitions.—As used in this section—

(1) the term “NAFTA country” has the meaning given that term in section 2(4) of the North American Free Trade Agreement Implementation Act; and

(2) the term “WTO member country” has the meaning given that term in section 2(10) of the Uruguay Round Agreements Act.

Based on Title 35, U.S.C., 1946 ed., §109 (Aug. 8, 1946, ch. 910, 60 Stat. 943).

Language has been changed and the last sentence has been broadened to refer to persons serving in connection with operations by or on behalf of the United States, instead of solely in connection with the prosecution of the war.

Section 2(4) of the North American Free Trade Agreement Implementation Act, referred to in subsec. (b), is classified to section 3301(4) of Title 19, Customs Duties.

1993—Pub. L. 103–182 amended section catchline and text generally. Prior to amendment, text read as follows: “In proceedings in the Patent and Trademark Office and in the courts, an applicant for a patent, or a patentee, may not establish a date of invention by reference to knowledge or use thereof, or other activity with respect thereto, in a foreign country, except as provided in sections 119 and 365 of this title. Where an invention was made by a person, civil or military, while domiciled in the United States and serving in a foreign country in connection with operations by or on behalf of the United States, he shall be entitled to the same rights of priority with respect to such invention as if the same had been made in the United States.”

1984—Pub. L. 98–622 substituted “Patent and Trademark Office” for “Patent Office”.

1975—Pub. L. 94–131 inserted in exception provision reference to section 365 of this title relating to priority of applications having benefit of filing date of prior applications.

Pub. L. 93–596 substituted “Patent and Trademark Office” for “Patent Office”.

(b) Any invention made, used or sold in outer space on a space object or component thereof that is carried on the registry of a foreign state in accordance with the Convention on Registration of Objects Launched into Outer Space, shall be considered to be made, used or sold within the United States for the purposes of this title if specifically so agreed in an international agreement between the United States and the state of registry.

(Added Pub. L. 101–580, §1(a), Nov. 15, 1990, 104 Stat. 2863.)

“(d)



1994—Pub. L. 103–465, title V, §532(c)(6), Dec. 8, 1994, 108 Stat. 4987, substituted “Application” for “Application for patent” in item 111 and “Benefit of earlier filing date; right of priority” for “Benefit of earlier filing date in foreign country; right of priority” in item 119.

Based on Title 35, U.S.C., 1946 ed., §33 (R.S. 4888, amended (1) Mar. 3, 1915, ch. 94, §1, 38 Stat. 958; (2) May 23, 1930, ch. 312, §2, 46 Stat. 376).

The corresponding section of existing statute is divided into an introductory section relating to the application generally (this section) and a section on the specification (sec. 112).

The parts of the application are specified and the requirement for signature is placed in this general section so as to insure that only one signature will suffice.

1994—Pub. L. 103–465 amended section generally. Prior to amendment, section read as follows: “Application for patent shall be made, or authorized to be made, by the inventor, except as otherwise provided in this title, in writing to the Commissioner. Such application shall include (1) a specification as prescribed by section 112 of this title; (2) a drawing as prescribed by section 113 of this title; and (3) an oath by the applicant as prescribed by section 115 of this title. The application must be accompanied by the fee required by law. The fee and oath may be submitted after the specification and any required drawing are submitted, within such period and under such conditions, including the payment of a surcharge, as may be prescribed by the Commissioner. Upon failure to submit the fee and oath within such prescribed period, the application shall be regarded as abandoned, unless it is shown to the satisfaction of the Commissioner that the delay in submitting the fee and oath was unavoidable. The filing date of an application shall be the date on which the specification and any required drawing are received in the Patent and Trademark Office.”

1982—Pub. L. 97–247 inserted “, or authorized to be made,” after “shall be made”, struck out the colon after “shall include”, struck out “signed by the applicant and” after “The application”, and inserted provisions that the fee and oath may be submitted after the specification and any required drawing are submitted, within such period and under such conditions, including the payment of a surcharge, as may be prescribed by the Commissioner, that upon failure to submit the fee and oath within such prescribed period, the application shall be regarded as abandoned, unless it is shown to the satisfaction of the Commissioner that the delay in submitting the fee and oath was unavoidable, and that the filing date of an application shall be the date on which the specification and any required drawing are received in the Patent and Trademark Office.

Amendment by Pub. L. 103–465 effective 6 months after Dec. 8, 1994, and applicable to all patent applications filed in the United States on or after that effective date, with provisions relating to earliest filed patent application, see section 534(b)(1), (3) of Pub. L. 103–465, set out as a note under section 154 of this title.

Amendment by Pub. L. 97–247 effective six months after Aug. 27, 1982, see section 17(c) of Pub. L. 97–247, set out as an Effective Date note under section 294 of this title.

Pub. L. 92–34, June 30, 1971, 85 Stat. 87, as amended by Pub. L. 93–596, §3, Jan. 2, 1975, 88 Stat. 1949, provided that:

“

“(b) No patent or trademark application, patent, or trademark registration shall be entitled to an earlier filing date under this section unless a verified statement by the applicant or owner of record claiming the filing date to which the application is believed to be entitled is filed in the Patent and Trademark Office within six months after enactment of this Act [June 30, 1971]. Such statement shall be maintained in the file of the application in the Patent and Trademark Office and shall be referred to in the patent or trademark registration when practicable.

“(c) When a statement filed under subsection (b) of this section appears unreasonable or defective on its face, or when the filing date of the patent or trademark application, patent, or trademark registration is called into question or is material in any inter partes proceeding in the Patent and Trademark Office or any proceeding in the courts, the applicant or owner of such application, patent, or trademark registration may be required to present evidence establishing the filing date to which the application is entitled. The filing date to which the application is entitled shall be determined on the basis of such evidence and any evidence introduced by an opposing party. The evidence shall be presented as directed by the Commissioner of Patents and Trademarks in proceedings in the Patent and Trademark Office or as directed by the courts in proceedings in the courts.

“

“(b) This section is applicable to title 35, United States Code, ‘Patents’; the Trademark Act of 1946, ch. 540, 60 Stat. 427, as amended [section 1051 et seq. of Title 15, Commerce and Trade]; the Atomic Energy Act of 1954, Pub.

L. 85–568, 72 Stat. 426 (1958), as amended [section 2451 et seq. of Title 42]. In cases involving the Atomic Energy Act of 1954 [section 2011 et seq. of Title 42] or the National Aeronautics and Space Act [section 2451 et seq. of Title 42], determinations of relief shall be made by a Board of Patent Interferences. In other cases determinations shall be made by the Commissioner of Patents and Trademarks.

“

Fees, see sections 41 and 42 of this title.

Provisions of this chapter applicable to applications for reissue of patents, see section 251 of this title.

This section is referred to in section 119 of this title.

The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.

The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.

A claim may be written in independent or, if the nature of the case admits, in dependent or multiple dependent form.

Subject to the following paragraph, a claim in dependent form shall contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed. A claim in dependent form shall be construed to incorporate by reference all the limitations of the claim to which it refers.

A claim in multiple dependent form shall contain a reference, in the alternative only, to more than one claim previously set forth and then specify a further limitation of the subject matter claimed. A multiple dependent claim shall not serve as a basis for any other multiple dependent claim. A multiple dependent claim shall be construed to incorporate by reference all the limitations of the particular claim in relation to which it is being considered.

An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.

(July 19, 1952, ch. 950, 66 Stat. 798; July 24, 1965, Pub. L. 89–83, §9, 79 Stat. 261; Nov. 14, 1975, Pub. L. 94–131, §7, 89 Stat. 691.)

The sentence relating to signature of the specification is omitted in view of the general requirement for a signature in section 111.

The last sentence is omitted for inclusion in the chapter relating to plant patents.

The clause relating to machines is omitted as unnecessary and the requirement for disclosing the best mode of carrying out the invention is stated as generally applicable to all types of invention (derived from Title 35, U.S.C., 1946 ed., §69, first defense).

The clause relating to the claim is made a separate paragraph to emphasize the distinction between the description and the claim or definition, and the language is modified.

A new paragraph relating to functional claims is added.

1975—Pub. L. 94–131 substituted provision authorizing the writing of claims, if the nature of the case admits, in dependent or multiple dependent form for prior provision for writing claims in dependent form, required claims in dependent form to contain a reference to a claim previously set forth and then specify a further limitation of the subject matter claimed, substituted text respecting construction of a claim in dependent form so as to incorporate by reference all the limitations of the claim to which it refers for prior text for construction of a dependent claim to include all the limitations of the claim incorporated by reference into the dependent claim, and inserted paragraph respecting certain requirements for claims in multiple dependent form.

1965—Pub. L. 89–83 permitted a claim to be written in independent or dependent form, and if in dependent form, required it to be construed to include all the limitations of the claim incorporated by reference into the dependent claim.

Amendment by Pub. L. 94–131 effective Jan. 24, 1978, and applicable on and after that date to patent applications filed in the United States and to international applications, where applicable, see section 11 of Pub. L. 94–131, set out as an Effective Date note under section 351 of this title.

Reissue of defective patents, see section 251 of this title.

This section is referred to in sections 41, 111, 119, 120, 157, 162, 282 of this title.

The applicant shall furnish a drawing where necessary for the understanding of the subject matter sought to be patented. When the nature of such subject matter admits of illustration by a drawing and the applicant has not furnished such a drawing, the Commissioner may require its submission within a time period of not less than two months from the sending of a notice thereof. Drawings submitted after the filing date of the application may not be used (i) to overcome any insufficiency of the specification due to lack of an enabling disclosure or otherwise inadequate disclosure therein, or (ii) to supplement the original disclosure thereof for the purpose of interpretation of the scope of any claim.

(July 19, 1952, ch. 950, 66 Stat. 799; Nov. 14, 1975, Pub. L. 94–131, §8, 89 Stat. 691.)

Based on Title 35, U.S.C., 1946 ed., §34, part (R.S. 4889, amended Mar. 3, 1915, ch. 94, §2, 38 Stat. 958).

The requirement for signature in the corresponding section of existing statute is omitted; regulations of the Patent Office can take care of any substitute. A redundant clause is omitted.

1975—Pub. L. 94–131 substituted provisions respecting drawings requiring necessary-for-understanding drawings and submission of drawings within prescribed time period and limiting use of drawings submitted after filing date of application for prior provision requiring the applicant to furnish a drawing when the nature of the case admitted it.

Amendment by Pub. L. 94–131 effective Jan. 24, 1978, and applicable on and after that date to patent applications filed in the United States and to international applications, where applicable, see section 11 of Pub. L. 94–131, set out as an Effective Date note under section 351 of this title.

Annexation of drawings to issued patent, see section 154 of this title.

Design patents, see section 171 of this title.

This section is referred to in section 111 of this title.

The Commissioner may require the applicant to furnish a model of convenient size to exhibit advantageously the several parts of his invention.

When the invention relates to a composition of matter, the Commissioner may require the applicant to furnish specimens or ingredients for the purpose of inspection or experiment.

(July 19, 1952, ch. 950, 66 Stat. 799.)

Based on Title 35, U.S.C., 1946 ed., §34, part (R.S. 4890 and 4891).

The change in language in the second paragraph broadens the requirement for specimens.

The applicant shall make oath that he believes himself to be the original and first inventor of the process, machine, manufacture, or composition of matter, or improvement thereof, for which he solicits a patent; and shall state of what country he is a citizen. Such oath may be made before any person within the United States authorized by law to administer oaths, or, when, made in a foreign country, before any diplomatic or consular officer of the United States authorized to administer oaths, or before any officer having an official seal and authorized to administer oaths in the foreign country in which the applicant may be, whose authority is proved by certificate of a diplomatic or consular officer of the United States, or apostille of an official designated by a foreign country which, by treaty or convention, accords like effect to apostilles of designated officials in the United States, and such oath shall be valid if it complies with the laws of the state or country where made. When the application is made as provided in this title by a person other than the inventor, the oath may be so varied in form that it can be made by him.

(July 19, 1952, ch. 950, 66 Stat. 799; Aug. 27, 1982, Pub. L. 97–247, §14(a), 96 Stat. 321.)

Based on Title 35, U.S.C., 1946 ed., §35 (R.S. 4892, amended (1) Mar. 3, 1903, ch. 1019, §2, 32 Stat. 1225, 1226, (2) May 23, 1930, ch. 312, §3, 46 Stat. 376).

The expression at the end of the second sentence is added to avoid application of the District of Columbia law to oaths taken outside the District.

Changes in language are made.

1982—Pub. L. 97–247 substituted “is” for “shall be” after “whose authority”, and inserted “, or apostille of an official designated by a foreign country which, by treaty or convention, accords like effect to apostilles of designated officials in the United States”.

Amendment by Pub. L. 97–247 effective Aug. 27, 1982, see section 17(a) of Pub. L. 97–247, set out as a note under section 41 of this title.

Consular officers authorized to administer oaths, see sections 4215 and 4221 of Title 22, Foreign Relations and Intercourse.

This section is referred to in sections 111, 371 of this title.

When an invention is made by two or more persons jointly, they shall apply for patent jointly and each make the required oath, except as otherwise provided in this title. Inventors may apply for a patent jointly even though (1) they did not physically work together or at the same time, (2) each did not make the same type or amount of contribution, or (3) each did not make a contribution to the subject matter of every claim of the patent.

If a joint inventor refuses to join in an application for patent or cannot be found or reached after diligent effort, the application may be made by the other inventor on behalf of himself and the omitted inventor. The Commissioner, on proof of the pertinent facts and after such notice to the omitted inventor as he prescribes, may grant a patent to the inventor making the application, subject to the same rights which the omitted inventor would have had if he had been joined. The omitted inventor may subsequently join in the application.

Whenever through error a person is named in an application for patent as the inventor, or through error an inventor is not named in an application, and such error arose without any deceptive intention on his part, the Commissioner may permit the application to be amended accordingly, under such terms as he prescribes.

(July 19, 1952, ch. 950, 66 Stat. 799; Aug. 27, 1982, Pub. L. 97–247, §6(a), 96 Stat. 320; Nov. 8, 1984, Pub. L. 98–622, title I, §104(a), 98 Stat. 3384.)

The first paragraph is implied in the present statutes, and the part of the last paragraph relating to omission of an erroneously joined inventor is in the Patent Office rules. The remainder is new and provides for the correction of a mistake in erroneously joining a person as inventor, and for filing an application when one of several joint inventors cannot be found. This section is ancillary to section 256.

1984—Pub. L. 98–622 amended first par. generally, striking out “and each sign the application” after “patent jointly” and inserting sentence beginning “Inventors may apply”.

1982—Pub. L. 97–247 substituted “Inventors” for “Joint inventors” as section catchline, and substituted “through error a person is named in an application for patent as the inventor, or through error an inventor is not named in an application” for “a person is joined in an application for patent as joint inventor through error, or a joint inventor is not included in an application through error”.

Amendment by Pub. L. 98–622 applicable to all United States patents granted before, on, or after Nov. 8, 1984, and to all applications for United States patents pending on or filed after that date, except as otherwise provided, see section 106 of Pub. L. 98–622, set out as a note under section 103 of this title.

Amendment by Pub. L. 97–247 effective six months after Aug. 27, 1982, see section 17(c) of Pub. L. 97–247, set out as an Effective Date note under section 294 of this title.

Joint owners, see section 262 of this title.

Legal representatives of deceased inventors and of those under legal incapacity may make application for patent upon compliance with the requirements and on the same terms and conditions applicable to the inventor.

(July 19, 1952, ch. 950, 66 Stat. 799.)

Based on Title 35, U.S.C., 1946 ed., §46 (R.S. 4896, amended (1) Feb. 28, 1899, ch. 227, 30 Stat. 915, (2) Mar. 3, 1903, ch. 1019, §3, 32 Stat. 1225, 1226, (3) May 23, 1908, ch. 188, 35 Stat. 245).

The language has been considerably simplified.

Fees for application for original or reissue of patent, see section 41 of this title.

Whenever an inventor refuses to execute an application for patent, or cannot be found or reached after diligent effort, a person to whom the inventor has assigned or agreed in writing to assign the invention or who otherwise shows sufficient proprietary interest in the matter justifying such action, may make application for patent on behalf of and as agent for the inventor on proof of the pertinent facts and a showing that such action is necessary to preserve the rights of the parties or to prevent irreparable damage; and the Commissioner may grant a patent to such inventor upon such notice to him as the Commissioner deems sufficient, and on compliance with such regulations as he prescribes.

(July 19, 1952, ch. 950, 66 Stat. 799.)

This section is new and provides for the filing of an application by another on behalf of the inventor in certain special hardship situations.

(a) An application for patent for an invention filed in this country by any person who has, or whose legal representatives or assigns have, previously regularly filed an application for a patent for the same invention in a foreign country which affords similar privileges in the case of applications filed in the United States or to citizens of the United States, shall have the same effect as the same application would have if filed in this country on the date on which the application for patent for the same invention was first filed in such foreign country, if the application in this country is filed within twelve months from the earliest date on which such foreign application was filed; but no patent shall be granted on any application for patent for an invention which had been patented or described in a printed publication in any country more than one year before the date of the actual filing of the application in this country, or which had been in public use or on sale in this country more than one year prior to such filing.

(b) No application for patent shall be entitled to this right of priority unless a claim therefor and a certified copy of the original foreign application, specification and drawings upon which it is based are filed in the Patent and Trademark Office before the patent is granted, or at such time during the pendency of the application as required by the Commissioner not earlier than six months after the filing of the application in this country. Such certification shall be made by the patent office of the foreign country in which filed and show the date of the application and of the filing of the specification and other papers. The Commissioner may require a translation of the papers filed if not in the English language and such other information as he deems necessary.

(c) In like manner and subject to the same conditions and requirements, the right provided in this section may be based upon a subsequent regularly filed application in the same foreign country instead of the first filed foreign application, provided that any foreign application filed prior to such subsequent application has been withdrawn, abandoned, or otherwise disposed of, without having been laid open to public inspection and without leaving any rights outstanding, and has not served, nor thereafter shall serve, as a basis for claiming a right of priority.

(d) Applications for inventors’ certificates filed in a foreign country in which applicants have a right to apply, at their discretion, either for a patent or for an inventor's certificate shall be treated in this country in the same manner and have the same effect for purpose of the right of priority under this section as applications for patents, subject to the same conditions and requirements of this section as apply to applications for patents, provided such applicants are entitled to the benefits of the Stockholm Revision of the Paris Convention at the time of such filing.

(e)(1) An application for patent filed under section 111(a) or section 363 of this title for an invention disclosed in the manner provided by the first paragraph of section 112 of this title in a provisional application filed under section 111(b) of this title, by an inventor or inventors named in the provisional application, shall have the same effect, as to such invention, as though filed on the date of the provisional application filed under section 111(b) of this title, if the application for patent filed under section 111(a) or section 363 of this title is filed not later than 12 months after the date on which the provisional application was filed and if it contains or is amended to contain a specific reference to the provisional application.

(2) A provisional application filed under section 111(b) of this title may not be relied upon in any proceeding in the Patent and Trademark Office unless the fee set forth in subparagraph (A) or (C) of section 41(a)(1) of this title has been paid and the provisional application was pending on the filing date of the application for patent under section 111(a) or section 363 of this title.

(July 19, 1952, ch. 950, 66 Stat. 800; Oct. 3, 1961, Pub. L. 87–333, §1, 75 Stat. 748; July 28, 1972, Pub. L. 92–358, §1, 86 Stat. 501; Jan. 2, 1975, Pub. L. 93–596, §1, 88 Stat. 1949; Dec. 8, 1994, Pub. L. 103–465, title V, §532(b)(1), 108 Stat. 4985.)

Based on Title 35, U.S.C., 1946 ed., §32, second paragraph (R.S. 4887, second paragraph, amended (1) Mar. 3, 1903, ch. 1019, §1, 32 Stat. 1225, 1226, (2) June 19, 1936, ch. 594, 49 Stat. 1529, (3) Aug. 5, 1939, ch. 450, §1, 53 Stat. 1212).

The first paragraph is the same as the present law with changes in language. The references to designs have been removed for inclusion in another section and the opening clause has been modified to accord with actual practice and the requirements of the International Convention for the Protection of Industrial Property.

The second paragraph is new, making an additional procedural requirement for obtaining the right of priority. Copies of the foreign papers on which the right of priority is based are required so that the record of the United States patent will be complete in this country.

The Stockholm Revision of the Paris Convention, referred to in subsec. (d), means the Convention revising the Convention of the Union of Paris of Mar. 20, 1883, as revised, for the protection of industrial property, done at Stockholm July 14, 1967, entered into force for the United States Sept. 5, 1970, with the exception of Articles 1 through 12 which entered into force for the United States Aug. 25, 1973. See 21 UST 1583; 24 UST 2140; TIAS 6293, 7727.

1994—Pub. L. 103–465, in section catchline, struck out “in foreign country” after “date”, designated four undesignated paragraphs as subsecs. (a) to (d), and added subsec. (e).

1975—Pub. L. 93–596 substituted “Patent and Trademark Office” for “Patent Office”.

1972—Pub. L. 92–358 inserted last paragraph providing that under certain circumstances, applications for inventors’ certificate filed in a foreign country would be given the same priority as applications for patents, if the applicants are entitled to the benefits of the Stockholm Revision of the Paris Convention at the time of filing.

1961—Pub. L. 87–333 authorized the right provided by this section to be based upon a subsequent application in the same foreign country, instead of the first application, provided that any foreign application filed prior to such subsequent one was withdrawn, or otherwise disposed of, without having been open to public inspection and without leaving any rights outstanding, nor any basis for claiming priority.

Amendment by Pub. L. 103–465 effective 6 months after Dec. 8, 1994, and applicable to all patent applications filed in the United States on or after that effective date, with provisions relating to earliest filed patent application, see section 534(b)(1), (3) of Pub. L. 103–465, set out as a note under section 154 of this title.

Amendment by Pub. L. 93–596 effective Jan. 2, 1975, see section 4 of Pub. L. 93–596, set out as a note under section 1111 of Title 15, Commerce and Trade.

L. 92–358 provided that: “Section 1 of this Act [amending this section] shall take effect on the date when Articles 1–12 of the Paris Convention of March 20, 1883, for the Protection of Industrial Property, as revised at Stockholm, July 14, 1967, come into force with respect to the United States [Aug. 25, 1973] and shall apply only to applications thereafter filed in the United States.”

Amendment by Pub. L. 87–333 effective on the date when the Convention of Paris for the Protection of Industrial Property of March 20, 1883, as revised at Lisbon, Oct. 31, 1958, comes into force with respect to the United States [Jan. 4, 1962] and shall apply only to applications thereafter filed in the United States by persons entitled to the benefit of said convention, as revised at the time of such filing, see section 3 of Pub. L. 87–333, set out as a note under section 1126 of Title 15, Commerce and Trade.

Act Aug. 23, 1954, ch. 823, 68 Stat. 764, provided that the priority rights specified in section 101 of former Title 35, Patents, which arose before Apr. 1, 1950, were extended, with respect to inventions made subsequent to Jan. 1, 1946, in favor of certain Japanese and German nationals, to a date nine months after Aug. 23, 1954, subject to conditions and limitations specified in sections 104, 110, 112, and 114 of former title 35.

Application for foreign patent, see section 102 of this title.

Determination of priority of invention, see section 102 of this title.

Interferences, see section 135 of this title.

Right of priority in design patents, see section 172 of this title.

This section is referred to in sections 104, 111, 154, 172, 373 of this title.

An application for patent for an invention disclosed in the manner provided by the first paragraph of section 112 of this title in an application previously filed in the United States, or as provided by section 363 of this title, which is filed by an inventor or inventors named in the previously filed application shall have the same effect, as to such invention, as though filed on the date of the prior application, if filed before the patenting or abandonment of or termination of proceedings on the first application or on an application similarly entitled to the benefit of the filing date of the first application and if it contains or is amended to contain a specific reference to the earlier filed application.

(July 19, 1952, ch. 950, 66 Stat. 800; Nov. 14, 1975, Pub. L. 94–131, §9, 89 Stat. 691; Nov. 8, 1984, Pub. L. 98–622, title I, §104(b), 98 Stat. 3385.)

This section represents present law not expressed in the statute, except for the added requirement that the first application must be specifically mentioned in the second.

1984—Pub. L. 98–622 substituted “which is filed by an inventor or inventors named in the previously filed application” for “by the same inventor”.

1975—Pub. L. 94–131 inserted “, or as provided by section 363 of this title,” after “filed in the United States”.

Amendment by Pub. L. 98–622 applicable to all United States patents granted before, on, or after Nov. 8, 1984, and to all applications for United States patents pending on or filed after that date, except as otherwise provided, see section 106 of Pub. L. 98–622, set out as a note under section 103 of this title.

Amendment by Pub. L. 94–131 effective Jan. 24, 1978, and applicable on and after that date to patent applications filed in the United States and to international applications, where applicable, see section 11 of Pub. L. 94–131, set out as an Effective Date note under section 351 of this title.

Specification, see section 112 of this title.

This section is referred to in sections 111, 121, 154, 365, 373 of this title.

If two or more independent and distinct inventions are claimed in one application, the Commissioner may require the application to be restricted to one of the inventions. If the other invention is made the subject of a divisional application which complies with the requirements of section 120 of this title it shall be entitled to the benefit of the filing date of the original application. A patent issuing on an application with respect to which a requirement for restriction under this section has been made, or on an application filed as a result of such a requirement, shall not be used as a reference either in the Patent and Trademark Office or in the courts against a divisional application or against the original application or any patent issued on either of them, if the divisional application is filed before the issuance of the patent on the other application. If a divisional application is directed solely to subject matter described and claimed in the original application as filed, the Commissioner may dispense with signing and execution by the inventor. The validity of a patent shall not be questioned for failure of the Commissioner to require the application to be restricted to one invention.

(July 19, 1952, ch. 950, 66 Stat. 800; Jan. 2, 1975, Pub. L. 93–596, §1, 88 Stat. 1949.)

This section enacts as law existing practice with respect to division, at the same time introducing a number of changes. Division is made discretionary with the Commissioner. The requirements of section 120 are made applicable and neither of the resulting patents can be held invalid over the other merely because of their being divided in several patents. In some cases a divisional application may be filed by the assignee.

1975—Pub. L. 93–596 substituted “Patent and Trademark Office” for “Patent Office”.

Amendment by Pub. L. 93–596 effective Jan. 2, 1975, see section 4 of Pub. L. 93–596, set out as a note under section 1111 of Title 15, Commerce and Trade.

(July 19, 1952, ch. 950, 66 Stat. 801; Jan. 2, 1975, Pub. L. 93–596, §1, 88 Stat. 1949.)

This section enacts the Patent Office rule of secrecy of applications.

1975—Pub. L. 93–596 substituted “Patent and Trademark Office” for “Patent Office”.

Amendment by Pub. L. 93–596 effective Jan. 2, 1975, see section 4 of Pub. L. 93–596, set out as a note under section 1111 of Title 15, Commerce and Trade.

(July 19, 1952, ch. 950, 66 Stat. 801.)

Based on Title 35, U.S.C., 1946 ed., §36 (R.S. 4893).

The first part is revised in language and amplified. The phrase “and that the invention is sufficiently useful and important” is omitted as unnecessary, the requirements for patentability being stated in sections 101, 102 and 103.

Issue of patent, generally, see section 151 et seq. of this title.

Patentability of invention generally, see section 100 et seq. of this title.

This section is referred to in section 111 of this title.

Whenever, on examination, any claim for a patent is rejected, or any objection or requirement made, the Commissioner shall notify the applicant thereof, stating the reasons for such rejection, or objection or requirement, together with such information and references as may be useful in judging of the propriety of continuing the prosecution of his application; and if after receiving such notice, the applicant persists in his claim for a patent, with or without amendment, the application shall be reexamined. No amendment shall introduce new matter into the disclosure of the invention.

(July 19, 1952, ch. 950, 66 Stat. 801.)

Based on Title 35, U.S.C., 1946 ed., §51 (R.S. 4903, amended Aug. 5, 1939, ch. 452, §1, 53 Stat. 1213).

Upon failure of the applicant to prosecute the application within six months after any action therein, of which notice has been given or mailed to the applicant, or within such shorter time, not less than thirty days, as fixed by the Commissioner in such action, the application shall be regarded as abandoned by the parties thereto, unless it be shown to the satisfaction of the Commissioner that such delay was unavoidable.

(July 19, 1952, ch. 950, 66 Stat. 801.)

Based on Title 35, U.S.C., 1946 ed., §37 (R.S. 4894, amended (1) Mar. 3, 1897, ch. 391, §4, 29 Stat. 692, 693, (2) July 6, 1916, ch. 225, §1, 39 Stat. 345, 347–8, (3) Mar. 2, 1927, ch. 273, §1, 44 Stat. 1335, (4) Aug. 7, 1939, ch. 568, 53 Stat. 1264).

Amendment by Pub. L. 98–622 effective three months after Nov. 8, 1984, see section 207 of Pub. L. 98–622, set out as a note under section 7 of this title.

Appeals to Commissioner from decisions of examiners on applications for registration of trade-marks, see section 1070 of Title 15, Commerce and Trade.

Board of Appeals, composition and duties, see section 7 of this title.

This section is referred to in sections 141, 145, 154, 306 of this title.

(a) Whenever an application is made for a patent which, in the opinion of the Commissioner, would interfere with any pending application, or with any unexpired patent, an interference may be declared and the Commissioner shall give notice of such declaration to the applicants, or applicant and patentee, as the case may be. The Board of Patent Appeals and Interferences shall determine questions of priority of the inventions and may determine questions of patentability. Any final decision, if adverse to the claim of an applicant, shall constitute the final refusal by the Patent and Trademark Office of the claims involved, and the Commissioner may issue a patent to the applicant who is adjudged the prior inventor. A final judgment adverse to a patentee from which no appeal or other review has been or can be taken or had shall constitute cancellation of the claims involved in the patent, and notice of such cancellation shall be endorsed on copies of the patent distributed after such cancellation by the Patent and Trademark Office.

(b) A claim which is the same as, or for the same or substantially the same subject matter as, a claim of an issued patent may not be made in any application unless such a claim is made prior to one year from the date on which the patent was granted.

(c) Any agreement or understanding between parties to an interference, including any collateral agreements referred to therein, made in connection with or in contemplation of the termination of the interference, shall be in writing and a true copy thereof filed in the Patent and Trademark Office before the termination of the interference as between the said parties to the agreement or understanding. If any party filing the same so requests, the copy shall be kept separate from the file of the interference, and made available only to Government agencies on written request, or to any person on a showing of good cause. Failure to file the copy of such agreement or understanding shall render permanently unenforceable such agreement or understanding and any patent of such parties involved in the interference or any patent subsequently issued on any application of such parties so involved. The Commissioner may, however, on a showing of good cause for failure to file within the time prescribed, permit the filing of the agreement or understanding during the six-month period subsequent to the termination of the interference as between the parties to the agreement or understanding.

The Commissioner shall give notice to the parties or their attorneys of record, a reasonable time prior to said termination, of the filing requirement of this section. If the Commissioner gives such notice at a later time, irrespective of the right to file such agreement or understanding within the six-month period on a showing of good cause, the parties may file such agreement or understanding within sixty days of the receipt of such notice.

Any discretionary action of the Commissioner under this subsection shall be reviewable under section 10 of the Administrative Procedure Act.

(d) Parties to a patent interference, within such time as may be specified by the Commissioner by regulation, may determine such contest or any aspect thereof by arbitration. Such arbitration shall be governed by the provisions of title 9 to the extent such title is not inconsistent with this section. The parties shall give notice of any arbitration award to the Commissioner, and such award shall, as between the parties to the arbitration, be dispositive of the issues to which it relates.

(D) Each certificate of interim extension under this paragraph shall be recorded in the official file of the patent and shall be considered part of the original patent.

(E) Any interim extension granted under this paragraph shall terminate at the end of the 60-day period beginning on the date on which the product involved receives permission for commercial marketing or use, except that, if within that 60-day period the applicant notifies the Commissioner of such permission and submits any additional information under paragraph (1) of this subsection not previously contained in the application for interim extension, the patent shall be further extended, in accordance with the provisions of this section—

(i) for not to exceed 5 years from the date of expiration of the original patent term; or

Such certificate shall be recorded in the official file of the patent and shall be considered as part of the original patent.

(2) If the term of a patent for which an application has been submitted under subsection (d)(1) would expire before a certificate of extension is issued or denied under paragraph (1) respecting the application, the Commissioner shall extend, until such determination is made, the term of the patent for periods of up to one year if he determines that the patent is eligible for extension.

Each individual to whom the application is disclosed shall sign a dated acknowledgment thereof, which acknowledgment shall be entered in the file of the application. If, in the opinion of the Atomic Energy Commission, the Secretary of a Defense Department, or the chief officer of another department or agency so designated, the publication or disclosure of the invention by the granting of a patent therefor would be detrimental to the national security, the Atomic Energy Commission, the Secretary of a Defense Department, or such other chief officer shall notify the Commissioner and the Commissioner shall order that the invention be kept secret and shall withhold the grant of a patent for such period as the national interest requires, and notify the applicant thereof. Upon proper showing by the head of the department or agency who caused the secrecy order to be issued that the examination of the application might jeopardize the national interest, the Commissioner shall thereupon maintain the application in a sealed condition and notify the applicant thereof. The owner of an application which has been placed under a secrecy order shall have a right to appeal from the order to the Secretary of Commerce under rules prescribed by him.

An invention shall not be ordered kept secret and the grant of a patent withheld for a period of more than one year. The Commissioner shall renew the order at the end thereof, or at the end of any renewal period, for additional periods of one year upon notification by the head of the department or the chief officer of the agency who caused the order to be issued that an affirmative determination has been made that the national interest continues so to require. An order in effect, or issued, during a time when the United States is at war, shall remain in effect for the duration of hostilities and one year following cessation of hostilities. An order in effect, or issued, during a national emergency declared by the President shall remain in effect for the duration of the national emergency and six months thereafter. The Commissioner may rescind any order upon notification by the heads of the departments and the chief officers of the agencies who caused the order to be issued that the publication or disclosure of the invention is no longer deemed detrimental to the national security.

This section is referred to in sections 154, 182, 183, 184, 185, 186 of this title.

The invention disclosed in an application for patent subject to an order made pursuant to section 181 of this title may be held abandoned upon its being established by the Commissioner that in violation of said order the invention has been published or disclosed or that an application for a patent therefor has been filed in a foreign country by the inventor, his successors, assigns, or legal representatives, or anyone in privity with him or them, without the consent of the Commissioner. The abandonment shall be held to have occurred as of the time of violation. The consent of the Commissioner shall not be given without the concurrence of the heads of the departments and the chief officers of the agencies who caused the order to be issued. A holding of abandonment shall constitute forfeiture by the applicant, his successors, assigns, or legal representatives, or anyone in privity with him or them, of all claims against the United States based upon such invention.

(July 19, 1952, ch. 950, 66 Stat. 806.)

Language is changed.

An applicant, his successors, assigns, or legal representatives, whose patent is withheld as herein provided, shall have the right, beginning at the date the applicant is notified that, except for such order, his application is otherwise in condition for allowance, or February 1, 1952, whichever is later, and ending six years after a patent is issued thereon, to apply to the head of any department or agency who caused the order to be issued for compensation for the damage caused by the order of secrecy and/or for the use of the invention by the Government, resulting from his disclosure. The right to compensation for use shall begin on the date of the first use of the invention by the Government. The head of the department or agency is authorized, upon the presentation of a claim, to enter into an agreement with the applicant, his successors, assigns, or legal representatives, in full settlement for the damage and/or use. This settlement agreement shall be conclusive for all purposes notwithstanding any other provision of law to the contrary. If full settlement of the claim cannot be effected, the head of the department or agency may award and pay to such applicant, his successors, assigns, or legal representatives, a sum not exceeding 75 per centum of the sum which the head of the department or agency considers just compensation for the damage and/or use. A claimant may bring suit against the United States in the United States Court of Federal Claims or in the District Court of the United States for the district in which such claimant is a resident for an amount which when added to the award shall constitute just compensation for the damage and/or use of the invention by the Government. The owner of any patent issued upon an application that was subject to a secrecy order issued pursuant to section 181 of this title, who did not apply for compensation as above provided, shall have the right, after the date of issuance of such patent, to bring suit in the United States Court of Federal Claims for just compensation for the damage caused by reason of the order of secrecy and/or use by the Government of the invention resulting from his disclosure. The right to compensation for use shall begin on the date of the first use of the invention by the Government. In a suit under the provisions of this section the United States may avail itself of all defenses it may plead in an action under section 1498 of title 28. This section shall not confer a right of action on anyone or his successors, assigns, or legal representatives who, while in the full-time employment or service of the United States, discovered, invented, or developed the invention on which the claim is based.

This section is referred to in section 157 of this title.

Except when authorized by a license obtained from the Commissioner a person shall not file or cause or authorize to be filed in any foreign country prior to six months after filing in the United States an application for patent or for the registration of a utility model, industrial design, or model in respect of an invention made in this country. A license shall not be granted with respect to an invention subject to an order issued by the Commissioner pursuant to section 181 of this title without the concurrence of the head of the departments and the chief officers of the agencies who caused the order to be issued. The license may be granted retroactively where an application has been filed abroad through error and without deceptive intent and the application does not disclose an invention within the scope of section 181 of this title.

The term “application” when used in this chapter includes applications and any modifications, amendments, or supplements thereto, or divisions thereof.

The scope of a license shall permit subsequent modifications, amendments, and supplements containing additional subject matter if the application upon which the request for the license is based is not, or was not, required to be made available for inspection under section 181 of this title and if such modifications, amendments, and supplements do not change the general nature of the invention in a manner which would require such application to be made available for inspection under such section 181. In any case in which a license is not, or was not, required in order to file an application in any foreign country, such subsequent modifications, amendments, and supplements may be made, without a license, to the application filed in the foreign country if the United States application was not required to be made available for inspection under section 181 and if such modifications, amendments, and supplements do not, or did not, change the general nature of the invention in a manner which would require the United States application to have been made available for inspection under such section 181.

(b)(1) The rights of the Government under subsection (a) shall not be exercised by a Federal agency unless it first determines that at least one of the conditions identified in clauses (i) through (iv) of subsection (a) exists. Except in the case of subsection (a)(iii), the agency shall file with the Secretary of Commerce, within thirty days after the award of the applicable funding agreement, a copy of such determination. In the case of a determination under subsection (a)(ii), the statement shall include an analysis justifying the determination. In the case of determinations applicable to funding agreements with small business firms, copies shall also be sent to the Chief Counsel for Advocacy of the Small Business Administration. If the Secretary of Commerce believes that any individual determination or pattern of determinations is contrary to the policies and objectives of this chapter or otherwise not in conformance with this chapter, the Secretary shall so advise the head of the agency concerned and the Administrator of the Office of Federal Procurement Policy, and recommend corrective actions.

(2) Whenever the Administrator of the Office of Federal Procurement Policy has determined that one or more Federal agencies are utilizing the authority of clause (i) or (ii) of subsection (a) of this section in a manner that is contrary to the policies and objectives of this chapter, the Administrator is authorized to issue regulations describing classes of situations in which agencies may not exercise the authorities of those clauses.

(3) At least once every 5 years, the Comptroller General shall transmit a report to the Committees on the Judiciary of the Senate and House of Representatives on the manner in which this chapter is being implemented by the agencies and on such other aspects of Government patent policies and practices with respect to federally funded inventions as the Comptroller General believes appropriate.

(4) If the contractor believes that a determination is contrary to the policies and objectives of this chapter or constitutes an abuse of discretion by the agency, the determination shall be subject to the last paragraph of section 203(2).

(c) Each funding agreement with a small business firm or nonprofit organization shall contain appropriate provisions to effectuate the following:

(1) That the contractor disclose each subject invention to the Federal agency within a reasonable time after it becomes known to contractor personnel responsible for the administration of patent matters, and that the Federal Government may receive title to any subject invention not disclosed to it within such time.

(2) That the contractor make a written election within two years after disclosure to the Federal agency (or such additional time as may be approved by the Federal agency) whether the contractor will retain title to a subject invention: *Provided*, That in any case where publication, on sale, or public use, has initiated the one year statutory period in which valid patent protection can still be obtained in the United States, the period for election may be shortened by the Federal agency to a date that is not more than sixty days prior to the end of the statutory period: *And provided further*, That the Federal Government may receive title to any subject invention in which the contractor does not elect to retain rights or fails to elect rights within such times.

(3) That a contractor electing rights in a subject invention agrees to file a patent application prior to any statutory bar date that may occur under this title due to publication, on sale, or public use, and shall thereafter file corresponding patent applications in other countries in which it wishes to retain title within reasonable times, and that the Federal Government may receive title to any subject inventions in the United States or other countries in which the contractor has not filed patent applications on the subject invention within such times.

(4) With respect to any invention in which the contractor elects rights, the Federal agency shall have a nonexclusive, nontransferrable, irrevocable, paid-up license to practice or have practiced for or on behalf of the United States any subject invention throughout the world: *Provided*, That the funding agreement may provide for such additional rights; 3 including the right to assign or have assigned foreign patent rights in the subject invention, as are determined by the agency as necessary for meeting the obligations of the United States under any treaty, international agreement, arrangement of cooperation, memorandum of understanding, or similar arrangement, including military agreement relating to weapons development and production.

(5) The right of the Federal agency to require periodic reporting on the utilization or efforts at obtaining utilization that are being made by the contractor or his licensees or assignees: *Provided*, That any such information as well as any information on utilization or efforts at obtaining utilization obtained as part of a proceeding under section 203 of this chapter shall be treated by the Federal agency as commercial and financial information obtained from a person and privileged and confidential and not subject to disclosure under section 552 of title 5 of the United States Code.

(6) An obligation on the part of the contractor, in the event a United States patent application is filed by or on its behalf or by any assignee of the contractor, to include within the specification of such application and any patent issuing thereon, a statement specifying that the invention was made with Government support and that the Government has certain rights in the invention.

(7) In the case of a nonprofit organization, (A) a prohibition upon the assignment of rights to a subject invention in the United States without the approval of the Federal agency, except where such assignment is made to an organization which has as one of its primary functions the management of inventions (provided that such assignee shall be subject to the same provisions as the contractor); (B) a requirement that the contractor share royalties with the inventor; (C) except with respect to a funding agreement for the operation of a Government-owned-contractor-operated facility, a requirement that the balance of any royalties or income earned by the contractor with respect to subject inventions, after payment of expenses (including payments to inventors) incidental to the administration of subject inventions, be utilized for the support of scientific research or education; (D) a requirement that, except where it proves infeasible after a reasonable inquiry, in the licensing of subject inventions shall be given to small business firms; and (E) with respect to a funding agreement for the operation of a Government-owned-contractor-operated facility, requirements (i) that after payment of patenting costs, licensing costs, payments to inventors, and other expenses incidental to the administration of subject inventions, 100 percent of the balance of any royalties or income earned and retained by the contractor during any fiscal year up to an amount equal to 5 percent of the annual budget of the facility, shall be used by the contractor for scientific research, development, and education consistent with the research and development mission and objectives of the facility, including activities that increase the licensing potential of other inventions of the facility; provided that if said balance exceeds 5 percent of the annual budget of the facility, that 75 percent of such excess shall be paid to the Treasury of the United States and the remaining 25 percent shall be used for the same purposes as described above in this clause (D); and (ii) that, to the extent it provides the most effective technology transfer, the licensing of subject inventions shall be administered by contractor employees on location at the facility.

(8) The requirements of sections 203 and 204 of this chapter.

(d) If a contractor does not elect to retain title to a subject invention in cases subject to this section, the Federal agency may consider and after consultation with the contractor grant requests for retention of rights by the inventor subject to the provisions of this Act and regulations promulgated hereunder.

(e) In any case when a Federal employee is a coinventor of any invention made under a funding agreement with a nonprofit organization or small business firm, the Federal agency employing such coinventor is authorized to transfer or assign whatever rights it may acquire in the subject invention from its employee to the contractor subject to the conditions set forth in this chapter.

(f)(1) No funding agreement with a small business firm or nonprofit organization shall contain a provision allowing a Federal agency to require the licensing to third parties of inventions owned by the contractor that are not subject inventions unless such provision has been approved by the head of the agency and a written justification has been signed by the head of the agency. Any such provision shall clearly state whether the licensing may be required in connection with the practice of a subject invention, a specifically identified work object, or both. The head of the agency may not delegate the authority to approve provisions or sign justifications required by this paragraph.

(2) A Federal agency shall not require the licensing of third parties under any such provision unless the head of the agency determines that the use of the invention by others is necessary for the practice of a subject invention or for the use of a work object of the funding agreement and that such action is necessary to achieve the practical application of the subject invention or work object. Any such determination shall be on the record after an opportunity for an agency hearing. Any action commenced for judicial review of such determination shall be brought within sixty days after notification of such determination.

Notwithstanding any other provision of this chapter, no small business firm or nonprofit organization which receives title to any subject invention and no assignee of any such small business firm or nonprofit organization shall grant to any person the exclusive right to use or sell any subject invention in the United States unless such person agrees that any products embodying the subject invention or produced through the use of the subject invention will be manufactured substantially in the United States. However, in individual cases, the requirement for such an agreement may be waived by the Federal agency under whose funding agreement the invention was made upon a showing by the small business firm, nonprofit organization, or assignee that reasonable but unsuccessful efforts have been made to grant licenses on similar terms to potential licensees that would be likely to manufacture substantially in the United States or that under the circumstances domestic manufacture is not commercially feasible.

(Added Pub. L. 96–517, §6(a), Dec. 12, 1980, 94 Stat. 3023.)

(b) A Federal agency shall normally grant the right to use or sell any federally owned invention in the United States only to a licensee that agrees that any products embodying the invention or produced through the use of the invention will be manufactured substantially in the United States.

(c)(1) Each Federal agency may grant exclusive or partially exclusive licenses in any invention covered by a federally owned domestic patent or patent application only if, after public notice and opportunity for filing written objections, it is determined that—

(A) the interests of the Federal Government and the public will best be served by the proposed license, in view of the applicant's intentions, plans, and ability to bring the invention to practical application or otherwise promote the invention's utilization by the public;

(B) the desired practical application has not been achieved, or is not likely expeditiously to be achieved, under any nonexclusive license which has been granted, or which may be granted, on the invention;

(C) exclusive or partially exclusive licensing is a reasonable and necessary incentive to call forth the investment of risk capital and expenditures to bring the invention to practical application or otherwise promote the invention's utilization by the public; and

(D) the proposed terms and scope of exclusivity are not greater than reasonably necessary to provide the incentive for bringing the invention to practical application or otherwise promote the invention's utilization by the public.

(2) A Federal agency shall not grant such exclusive or partially exclusive license under paragraph (1) of this subsection if it determines that the grant of such license will tend substantially to lessen competition or result in undue concentration in any section of the country in any line of commerce to which the technology to be licensed relates, or to create or maintain other situations inconsistent with the antitrust laws.

(3) First preference in the exclusive or partially exclusive licensing of federally owned inventions shall go to small business firms submitting plans that are determined by the agency to be within the capabilities of the firms and equally likely, if executed, to bring the invention to practical application as any plans submitted by applicants that are not small business firms.

(d) After consideration of whether the interests of the Federal Government or United States industry in foreign commerce will be enhanced, any Federal agency may grant exclusive or partially exclusive licenses in any invention covered by a foreign patent application or patent, after public notice and opportunity for filing written objections, except that a Federal agency shall not grant such exclusive or partially exclusive license if it determines that the grant of such license will tend substantially to lessen competition or result in undue concentration in any section of the United States in any line of commerce to which the technology to be licensed relates, or to create or maintain other situations inconsistent with antitrust laws.

(e) The Federal agency shall maintain a record of determinations to grant exclusive or partially exclusive licenses.

(f) Any grant of a license shall contain such terms and conditions as the Federal agency determines appropriate for the protection of the interests of the Federal Government and the public, including provisions for the following:

(2) the right of the Federal agency to terminate such license in whole or in part if it determines that the licensee is not executing the plan submitted with its request for a license and the licensee cannot otherwise demonstrate to the satisfaction of the Federal agency that it has taken or can be expected to take within a reasonable time, effective steps to achieve practical application of the invention;

(3) the right of the Federal agency to terminate such license in whole or in part if the licensee is in breach of an agreement obtained pursuant to paragraph (b) of this section; and

(4) the right of the Federal agency to terminate the license in whole or in part if the agency determines that such action is necessary to meet requirements for public use specified by Federal regulations issued after the date of the license and such requirements are not reasonably satisfied by the licensee.

1 Section catchline amended by Pub. L. 97–247 without corresponding amendment of chapter analysis.

Whenever any patent is, through error without any deceptive intention, deemed wholly or partly inoperative or invalid, by reason of a defective specification or drawing, or by reason of the patentee claiming more or less than he had a right to claim in the patent, the Commissioner shall, on the surrender of such patent and the payment of the fee required by law, reissue the patent for the invention disclosed in the original patent, and in accordance with a new and amended application, for the unexpired part of the term of the original patent. No new matter shall be introduced into the application for reissue.

The Commissioner may issue several reissued patents for distinct and separate parts of the thing patented, upon demand of the applicant, and upon payment of the required fee for a reissue for each of such reissued patents.

The provisions of this title relating to applications for patent shall be applicable to applications for reissue of a patent, except that application for reissue may be made and sworn to by the assignee of the entire interest if the application does not seek to enlarge the scope of the claims of the original patent.

No reissued patent shall be granted enlarging the scope of the claims of the original patent unless applied for within two years from the grant of the original patent.

(July 19, 1952, ch. 950, 66 Stat. 808.)

Based on Title 35, U.S.C., 1946 ed., §64 (R.S. 4916, amended May 24, 1928, ch. 730, 45 Stat. 732.)

The third paragraph incorporates by reference the requirements of other applications, and adds a new provision relating to application for reissue being made in certain cases by the assignee.

A two year period of limitation on applying for broadened reissues is added, codifying the present rule of decision with a fixed period.

Application for patent, see section 111 of this title.

Fee for application for reissue of patent, see section 41 of this title.

This section is referred to in section 282 of this title.

The surrender of the original patent shall take effect upon the issue of the reissued patent, and every reissued patent shall have the same effect and operation in law, on the trial of actions for causes thereafter arising, as if the same had been originally granted in such amended form, but in so far as the claims of the original and reissued patents are identical, such surrender shall not affect any action then pending nor abate any cause of action then existing, and the reissued patent, to the extent that its claims are identical with the original patent, shall constitute a continuation thereof and have effect continuously from the date of the original patent.

No reissued patent shall abridge or affect the right of any person or his successors in business who made, purchased or used prior to the grant of a reissue anything patented by the reissued patent, to continue the use of, or to sell to others to be used or sold, the specific thing so made, purchased or used, unless the making, using or selling of such thing infringes a valid claim of the reissued patent which was in the original patent. The court before which such matter is in question may provide for the continued manufacture, use or sale of the thing made, purchased or used as specified, or for the manufacture, use or sale of which substantial preparation was made before the grant of the reissue, and it may also provide for the continued practice of any process patented by the reissue, practice, or for the practice of which substantial preparation was made, prior to the grant of the reissue, to the extent and under such terms as the court deems equitable for the protection of investments made or business commenced before the grant of the reissue.

(July 19, 1952, ch. 950, 66 Stat. 808; Dec. 8, 1994, Pub. L. 103–465, title V, §533(b)(2), 108 Stat. 4989.)

Pub. L. 103–465, title V, §§533(b)(2), 534(a), (b)(3), Dec. 8, 1994, 108 Stat. 4989, 4990, provided that, effective on date that is one year after date on which the WTO Agreement enters into force with respect to the United States [Jan. 1, 1995], with provisions relating to earliest filed patent application, the second undesignated paragraph of this section is amended to read as follows:

A reissued patent shall not abridge or affect the right of any person or that person's successors in business who, prior to the grant of a reissue, made, purchased, offered to sell, or used within the United States, or imported into the United States, anything patented by the reissued patent, to continue the use of, to offer to sell, or to sell to others to be used, offered for sale, or sold, the specific thing so made, purchased, offered for sale, used, or imported unless the making, using, offering for sale, or selling of such thing infringes a valid claim of the reissued patent which was in the original patent. The court before which such matter is in question may provide for the continued manufacture, use, offer for sale, or sale of the thing made, purchased, offered for sale, used, or imported as specified, or for the manufacture, use, offer for sale, or sale in the United States of which substantial preparation was made before the grant of the reissue, and the court may also provide for the continued practice of any process patented by the reissue that is practiced, or for the practice of which substantial preparation was made, before the grant of the reissue, to the extent and under such terms as the court deems equitable for the protection of investments made or business commenced before the grant of the reissue.

Based on Title 35, U.S.C., 1946 ed., §64 (R.S. 4916, amended May 24, 1928, ch. 730, 45 Stat. 732.)

The first paragraph follows the present section with some rearrangement in language. The second paragraph adds new provisions for the protection of intervening rights, the court is given discretion to protect legitimate activities which would be adversely affected by the grant of a reissue and things made before the grant of the reissue are not subject to the reissue unless a claim of the original patent which is repeated in the reissue is infringed.

Amendment by Pub. L. 103–465 effective on date that is one year after date on which the WTO Agreement enters into force with respect to the United States [Jan. 1, 1995], with provisions relating to earliest filed patent application, see section 534(a), (b)(3) of Pub. L. 103–465, set out as a note under section 154 of this title.

This section is referred to in section 307 of this title.

Whenever, without any deceptive intention, a claim of a patent is invalid the remaining claims shall not thereby be rendered invalid. A patentee, whether of the whole or any sectional interest therein, may, on payment of the fee required by law, make disclaimer of any complete claim, stating therein the extent of his interest in such patent. Such disclaimer shall be in writing, and recorded in the Patent and Trademark Office; and it shall thereafter be considered as part of the original patent to the extent of the interest possessed by the disclaimant and by those claiming under him.

In like manner any patentee or applicant may disclaim or dedicate to the public the entire term, or any terminal part of the term, of the patent granted or to be granted.

(July 19, 1952, ch. 950, 66 Stat. 809; Jan. 2, 1975, Pub. L. 93–596, §1, 88 Stat. 1949.)

Based on Title 35, U.S.C., 1946 ed., §65 (R.S. 4917).

Language is changed and substantive changes are introduced; (1) only a claim as a whole may be disclaimed, and (2) the provision regarding delay is omitted. See preliminary general description of bill.

See section 288.

The second paragraph is new and provides for the disclaiming or dedication of an entire patent, or any terminal part of the term, for example, a patentee may disclaim the last three years of the term of his patent.

1975—Pub. L. 93–596 substituted “Patent and Trademark Office” for “Patent Office”.

Amendment by Pub. L. 93–596 effective Jan. 2, 1975, see section 4 of Pub. L. 93–596, set out as a note under section 1111 of Title 15, Commerce and Trade.

Costs when disclaimer not entered before suit, see section 288 of this title.

Fee for filing disclaimer, see section 41 of this title.

Whenever a mistake in a patent, incurred through the fault of the Patent and Trademark Office, is clearly disclosed by the records of the Office, the Commissioner may issue a certificate of correction stating the fact and nature of such mistake, under seal, without charge, to be recorded in the records of patents. A printed copy thereof shall be attached to each printed copy of the patent, and such certificate shall be considered as part of the original patent. Every such patent, together with such certificate, shall have the same effect and operation in law on the trial of actions for causes thereafter arising as if the same had been originally issued in such corrected form. The Commissioner may issue a corrected patent without charge in lieu of and with like effect as a certificate of correction.

(July 19, 1952, ch. 950, 66 Stat. 809; Jan. 2, 1975, Pub. L. 93–596, §1, 88 Stat. 1949.)

Based on Title 35, U.S.C., 1946 ed., §88 (Mar. 4, 1925, ch. 535, §1, 43 Stat. 1268).

The last sentence of the present section is omitted as obsolete. A sentence is added similar to a provision in the corresponding section in the trade-mark law, 15 U.S.C., 1946 ed., §1057(f), and provides that the Commissioner may issue a corrected patent instead of a certificate of correction.

1975—Pub. L. 93–596 substituted “Patent and Trademark Office” for “Patent Office” in section catchline and text.

Amendment by Pub. L. 93–596 effective Jan. 2, 1975, see section 4 of Pub. L. 93–596, set out as a note under section 1111 of Title 15, Commerce and Trade.

Whenever a mistake of a clerical or typographical nature, or of minor character, which was not the fault of the Patent and Trademark Office, appears in a patent and a showing has been made that such mistake occurred in good faith, the Commissioner may, upon payment of the required fee, issue a certificate of correction, if the correction does not involve such changes in the patent as would constitute new matter or would require re-examination. Such patent, together with the certificate, shall have the same effect and operation in law on the trial of actions for causes thereafter arising as if the same had been originally issued in such corrected form.

(July 19, 1952, ch. 950, 66 Stat. 809; Jan. 2, 1975, Pub. L. 93–596, §1, 88 Stat. 1949.)

This section providing for the correction of minor clerical errors made by the applicant, is new and follows a similar provision in the trade-mark law, 15 U.S.C., 1946 ed., §1057(g).

1975—Pub. L. 93–596 substituted “Patent and Trademark Office” for “Patent Office”.

Amendment by Pub. L. 93–596 effective Jan. 2, 1975, see section 4 of Pub. L. 93–596, set out as a note under section 1111 of Title 15, Commerce and Trade.

This section is referred to in section 41 of this title.

Whenever through error a person is named in an issued patent as the inventor, or through error an inventor is not named in an issued patent and such error arose without any deceptive intention on his part, the Commissioner may, on application of all the parties and assignees, with proof of the facts and such other requirements as may be imposed, issued a certificate correcting such error.

The error of omitting inventors or naming persons who are not inventors shall not invalidate the patent in which such error occurred if it can be corrected as provided in this section. The court before which such matter is called in question may order correction of the patent on notice and hearing of all parties concerned and the Commissioner shall issue a certificate accordingly.

(July 19, 1952, ch. 950, 66 Stat. 810; Aug. 27, 1982, Pub. L. 97–247, §6(b), 96 Stat. 320.)

This section is new and is companion to section 116.

The first two paragraphs provide for the correction of the inadvertent joining or nonjoining of a person as a joint inventor. The third paragraph provides that a patent shall not be invalid for such cause, and also provides that a court may order correction of a patent; the two sentences of this paragraph are independent.

1982—Pub. L. 97–247 substituted “Correction of named inventor” for “Misjoinder of inventor” as section catchline and, in text, substituted “Whenever through error a person is named in an issued patent as the inventor, or through error an inventor is not named in an issued patent and such error arose without any deceptive intention on his part, the Commissioner may, on application of all the parties and assignees, with proof of the facts and such other requirements as may be imposed, issue a certificate correcting such error” for “Whenever a patent is issued on the application of persons as joint inventors and it appears that one of such persons was not in fact a joint inventor, and that he was included as a joint inventor by error and without any deceptive intention, the Commissioner may, on application of all the parties and assignees, with proof of the facts and such other requirements as may be imposed, issue a certificate deleting the name of the erroneously joined person from the patent”, substituted “The error of omitting inventors or naming persons who are not inventors shall not invalidate the patent in which such error occurred if it can be corrected as provided in this section” for “Whenever a patent is issued and it appears that a person was a joint inventor, but was omitted by error and without deceptive intention on his part, the Commissioner may, on application of all the parties and assignees, with proof of the facts and such other requirements as may be imposed, issue a certificate adding his name to the patent as a joint inventor”, and struck out provision that the misjoinder or nonjoinder of joint inventors not invalidate a patent, if such error could be corrected as provided in this section.

All Government departments and agencies which have or may hereafter acquire title to inventions or the right to file patent applications abroad thereon, shall fully and continuously inform the Chairman of Government Patents Board [now Secretary of Commerce. See Ex. Ord. No. 10930 set out as a note below] concerning such inventions, except as provided in section 6 hereof, and shall make recommendations to the Chairman of Government Patents Board [now Secretary of Commerce] as to which of such inventions should receive patent protection by the United States abroad and the foreign jurisdictions in which such patent protection should be sought. The recommendations of such departments and agencies shall indicate the immediate or future industrial, commercial or other value of the invention concerned, including its value to public health.

3. The Chairman of Government Patents Board [now Secretary of Commerce] shall determine whether, and in what foreign jurisdictions, the United States should seek patents for such inventions, and, to the extent of appropriations available therefor, shall procure patent protection for such inventions, taking all action, consistent with existing law, necessary to acquire and maintain patent rights abroad. Such determinations of the said Department shall be made after full consultation with United States industry and commerce, with the Department of State, and with other Government agencies familiar with the technical, scientific, industrial, commercial or other economic or social factors affecting the invention involved, and after consideration of the availability of valid patent protection in the countries determined to be immediate or potential markets for, or producers of, products, processes, or services covered by or relating to the invention.

4. The Chairman of Government Patents Board [now Secretary of Commerce] shall administer foreign patents acquired by the United States under the terms of this order and shall issue licenses thereunder in accordance with law under such rules and regulations as he shall prescribe. Nationals of the United States shall be granted licenses on a nonexclusive royalty free basis except in such cases as he shall determine and proclaim it to be inconsistent with the public interest to issue such licenses on a nonexclusive royalty free basis.

5. The Department of State, in consultation with the Chairman of Government Patents Board [now Secretary of Commerce], shall negotiate arrangements among governments under which each government and its nationals shall have access to the foreign patents of the other participating governments. Patents relating to matters of public health may be licensed by the Chairman of Government Patents Board [now Secretary of Commerce], with the approval of the Secretary of State, to any country or its nationals upon such terms and conditions as are in accordance with law and as the Chairman of Government Patents Board [now Secretary of Commerce] determines to be appropriate, regardless of whether such country is a party to the arrangements provided for in this section.

6. There shall be exempted from the provisions of this order (a) all inventions within the jurisdiction of the Atomic Energy Commission except in such cases as the said Commission specifically authorizes the inclusion of an invention under the terms of this order; and (b) all other inventions officially classified as secret or confidential for reasons of the national security. Nothing in this order shall supersede the declassification policies and procedures established by Executive Orders Nos. 9568 of June 8, 1945, 9604 of August 25, 1945, and 9809 of December 12, 1946.

Energy Research and Development Administration terminated and functions vested by law in Administrator thereof transferred to Secretary of Energy (unless otherwise specifically provided) by sections 7151(a) and 7293 of Title 42.

Ex. Ord. No. 10096, Jan. 23, 1950, 15 F.R. 389, as amended by Ex. Ord. No. 10695, Jan. 16, 1957, 22 F.R. 365; Ex. Ord. No. 10930, Mar. 24, 1961, 26 F.R. 2583, provided:

NOW, THEREFORE, by virtue of the authority vested in me by the Constitution and statutes, and as President of the United States and Commander in Chief of the armed forces of the United States, in the interest of the establishment and operation of a uniform patent policy for the Government with respect to inventions made by Government employees, it is hereby ordered as follows:

1. The following basic policy is established for all Government agencies with respect to inventions hereafter made by any Government employee:

(a) The Government shall obtain the entire right, title, and interest in and to all inventions made by any Government employee (1) during working hours, or (2) with a contribution by the Government of facilities, equipment, materials, funds, or information, or of time or services of other Government employees on official duty, or (3) which bear a direct relation to or are made in consequence of the official duties of the inventor.

(b) In any case where the contribution of the Government, as measured by any one or more of the criteria set forth in paragraph (a) last above, to the invention, is insufficient equitably to justify a requirement of assignment to the Government of the entire right, title and interest to such invention, or in any case where the Government has insufficient interest in an invention to obtain entire right, title and interest therein (although the Government could obtain some under paragraph (a), above), the Government agency concerned, subject to the approval of the Chairman of the Government Patents Board [now Secretary of Commerce. See Ex. Ord. No. 10930 set out as a note below] (provided for in paragraph 3 of this order and hereinafter referred to as the Chairman), shall leave title to such invention in the employee, subject, however, to the reservation to the Government of a non-exclusive, irrevocable, royalty-free license in the invention with power to grant licenses for all governmental purposes, such reservation, in the terms thereof, to appear, where practicable, in any patent, domestic or foreign, which may issue on such invention.

(c) In applying the provisions of paragraphs (a) and (b), above, to the facts and circumstances relating to the making of any particular invention, it shall be presumed that an invention made by an employee who is employed or assigned (i) to invent or improve or perfect any art, machine, manufacture, or composition of matter, (ii) to conduct or perform research, development work, or both, (iii) to supervise, direct, coordinate, or review Government financed or conducted research, development work, or both, or (iv) to act in a liaison capacity among governmental or nongovernmental agencies or individuals engaged in such work, or made by an employee included within any other category of employees specified by regulations issued pursuant to section 4(b) hereof, falls within the provisions of paragraph (a), above, and it shall be presumed that any invention made by any other employee falls within the provisions of paragraph (b), above. Either presumption may be rebutted by the facts or circumstances attendant upon the conditions under which any particular invention is made and, notwithstanding the foregoing, shall not preclude a determination that the invention falls within the provisions of paragraph (d) next below.

(d) In any case wherein the Government neither (1) pursuant to the provisions of paragraph (a) above, obtains entire right, title and interest in and to an invention nor (2) pursuant to the provisions of paragraph (b) above, reserves a non-exclusive, irrevocable, royalty-free license in the invention with power to grant licenses for all governmental purposes, the Government shall leave the entire right, title and interest in and to the invention in the Government employee, subject to law.

(e) Actions taken, and rights acquired, under the foregoing provisions of this section, shall be reported to the Chairman [now Secretary of Commerce] in accordance with procedures established by him.

2. Subject to considerations of national security, or public health, safety, or welfare, the following basic policy is established for the collection, and dissemination to the public, of information concerning inventions resulting from Government research and development activities:

(a) When an invention is made under circumstances defined in paragraph 1(a) of this order giving the United States the right to title thereto, the Government agency concerned shall either prepare and file an application for patent therefor in the United States Patent Office [now Patent and Trademark Office] or make a full disclosure of the invention promptly to the Chairman [now Secretary of Commerce], who may, if he determines the Government interest so requires, cause application for patent to be filed or cause the invention to be fully disclosed by publication thereof: *Provided, however*, That, consistent with present practice of the Department of Agriculture, no application for patent shall, without the approval of the Secretary of Agriculture, be filed in respect of any variety of plant invented by any employee of that Department.

(b) [Revoked. Ex. Ord. No. 10695, Jan. 16, 1957, 22 F.R. 365]

3. (a) [Revoked. Ex. Ord. No. 10930, Mar. 24, 1961, 26 F.R. 2583]

(b) The Government Patents Board shall advise and confer with the Chairman concerning the operation of those aspects of the Government's patent policy which are affected by the provisions of this order or of Executive Order No. 9865, and suggest modifications or improvements where necessary.

(c) [Revoked. Ex. Ord. No. 10930, Mar. 24, 1961, 26 F.R. 2583]

(d) The Chairman shall establish such committees and other working groups as may be required to advise or assist him in the performance of any of his functions.

(e) The Chairman of the Government Patents Board [now Secretary of Commerce] and the Chairman of the Interdepartmental Committee on Scientific Research and Development (provided for by Executive Order No. 9912 of December 24, 1947), shall establish and maintain such mutual consultation as will effect the proper coordination of affairs of common concern.

4. With a view to obtaining uniform application of the policies set out in this order and uniform operations thereunder, the Chairman [now Secretary of Commerce] is authorized and directed:

(a) To consult and advise with Government agencies concerning the application and operation of the policies outlined herein;

(b) After consultation with the Government Patents Board, to formulate and submit to the President for approval such proposed rules and regulations as may be necessary or desirable to implement and effectuate the aforesaid policies, together with the recommendations of the Government Patents Board thereon;

(c) To submit annually a report to the President concerning the operation of such policies, and from time to time such recommendations for modification thereof as may be deemed desirable;

(d) To determine with finality any controversies or disputes between any Government agency and its employees, to the extent submitted by any party to the dispute, concerning the ownership of inventions made by such employees or rights therein; and

(e) To perform such other or further functions or duties as may from time to time be prescribed by the President or by statute.

5. The functions and duties of the Secretary of Commerce and the Department of Commerce under the provisions of Executive Order No. 9865 of June 14, 1947 are hereby transferred to the Chairman and the whole or any part of such functions and duties may be delegated by him to any Government agency or officer: *Provided*, That said Executive Order No. 9865 shall not be deemed to be amended or affected by any provision of this Executive order other than this paragraph 5.

6. Each Government agency shall take all steps appropriate to effectuate this order, including the promulgation of necessary regulations which shall not be inconsistent with this order or with regulations issued pursuant to paragraph 4(b) hereof.

7. As used in this Executive order, the next stated terms, in singular and plural, are defined as follows for the purposes hereof:

(a) “Government agency” includes any executive department and any independent commission, board, office, agency, authority, or other establishment of the Executive Branch of the Government of the United States (including any such independent regulatory commission or board, any such wholly-owned corporation, and the Smithsonian Institution), but excludes the Atomic Energy Commission.

(b) “Government employee” includes any officer or employee, civilian or military, of any Government agency, except such part-time consultants or employees as may be excluded by regulations promulgated pursuant to paragraph 4(b) hereof.

(c) “Invention” includes any art, machine, manufacture, design, or composition of matter, or any new and useful improvement thereof, or any variety of plant, which is or may be patentable under the patent laws of the United States.

Section 2 of Ex. Ord. 10695, Jan. 16, 1957, 22 F.R. 365, provided that: “The Chairman of the Government Patents Board is hereby authorized to transfer to the Department of Commerce any or all of the records heretofore prepared by the Board pursuant to paragraph 2(b) of Executive Order No. 10096.”

Ex. Ord. No. 10930, Mar. 24, 1961, 26 F.R. 2583, provided:

By virtue of the authority vested in me as President of the United States, it is ordered as follows:

John F. Kennedy.

Notwithstanding the provisions of sections 133 and 151 of this title, the Commissioner may extend the time for taking any action to three years, when an application has become the property of the United States and the head of the appropriate department or agency of the Government has certified to the Commissioner that the invention disclosed therein is important to the armament or defense of the United States.

(July 19, 1952, ch. 950, 66 Stat. 811.)

Based on Title 35, U.S.C., 1946 ed., §37 (R.S. 4894, amended (1) Mar. 3, 1897, ch. 391, §4, 29 Stat. 692, 693, (2) July 6, 1916, ch. 225, §1, 39 Stat. 345, 347–8, (3) Mar. 2, 1927, ch. 273, §1, 44 Stat. 1335, (4) Aug. 7, 1939, ch. 568, 53 Stat. 1264).

This provision, which appears as the last two sentences of the corresponding section of the present statute (see note to section 133) is made a separate section and rewritten in simpler form.


This chapter is referred to in section 154 of this title.

(a) Except as otherwise provided in this title, whoever without authority makes, uses or sells any patented invention, within the United States during the term of the patent therefor, infringes the patent.

(b) Whoever actively induces infringement of a patent shall be liable as an infringer.

(c) Whoever sells a component of a patented machine, manufacture, combination or composition, or a material or apparatus for use in practicing a patented process, constituting a material part of the invention, knowing the same to be especially made or especially adapted for use in an infringement of such patent, and not a staple article or commodity of commerce suitable for substantial noninfringing use, shall be liable as a contributory infringer.

(d) No patent owner otherwise entitled to relief for infringement or contributory infringement of a patent shall be denied relief or deemed guilty of misuse or illegal extension of the patent right by reason of his having done one or more of the following: (1) derived revenue from acts which if performed by another without his consent would constitute contributory infringement of the patent; (2) licensed or authorized another to perform acts which if performed without his consent would constitute contributory infringement of the patent; (3) sought to enforce his patent rights against infringement or contributory infringement; (4) refused to license or use any rights to the patent; or (5) conditioned the license of any rights to the patent or the sale of the patented product on the acquisition of a license to rights in another patent or purchase of a separate product, unless, in view of the circumstances, the patent owner has market power in the relevant market for the patent or patented product on which the license or sale is conditioned.

(e)(1) It shall not be an act of infringement to make, use, or sell a patented invention (other than a new animal drug or veterinary biological product (as those terms are used in the Federal Food, Drug, and Cosmetic Act and the Act of March 4, 1913) which is primarily manufactured using recombinant DNA, recombinant RNA, hybridoma technology, or other processes involving site specific genetic manipulation techniques) solely for uses reasonably related to the development and submission of information under a Federal law which regulates the manufacture, use, or sale of drugs or veterinary biological products.

(2) It shall be an act of infringement to submit—

(A) an application under section 505(j) of the Federal Food, Drug, and Cosmetic Act or described in section 505(b)(2) of such Act for a drug claimed in a patent or the use of which is claimed in a patent, or

(B) an application under section 512 of such Act or under the Act of March 4, 1913 (21 U.S.C. 151–158) for a drug or veterinary biological product which is not primarily manufactured using recombinant DNA, recombinant RNA, hybridoma technology, or other processes involving site specific genetic manipulation techniques and which is claimed in a patent or the use of which is claimed in a patent,

if the purpose of such submission is to obtain approval under such Act to engage in the commercial manufacture, use, or sale of a drug or veterinary biological product claimed in a patent or the use of which is claimed in a patent before the expiration of such patent.

(3) In any action for patent infringement brought under this section, no injunctive or other relief may be granted which would prohibit the making, using, or selling of a patented invention under paragraph (1).

(4) For an act of infringement described in paragraph (2)—

(A) the court shall order the effective date of any approval of the drug or veterinary biological product involved in the infringement to be a date which is not earlier than the date of the expiration of the patent which has been infringed,

(B) injunctive relief may be granted against an infringer to prevent the commercial manufacture, use, or sale of an approved drug or veterinary biological product, and

(C) damages or other monetary relief may be awarded against an infringer only if there has been commercial manufacture, use, or sale of an approved drug or veterinary biological product.

The remedies prescribed by subparagraphs (A), (B), and (C) are the only remedies which may be granted by a court for an act of infringement described in paragraph (2), except that a court may award attorney fees under section 285.

(f)(1) Whoever without authority supplies or causes to be supplied in or from the United States all or a substantial portion of the components of a patented invention, where such components are uncombined in whole or in part, in such manner as to actively induce the combination of such components outside of the United States in a manner that would infringe the patent if such combination occurred within the United States, shall be liable as an infringer.

(2) Whoever without authority supplies or causes to be supplied in or from the United States any component of a patented invention that is especially made or especially adapted for use in the invention and not a staple article or commodity of commerce suitable for substantial noninfringing use, where such component is uncombined in whole or in part, knowing that such component is so made or adapted and intending that such component will be combined outside of the United States in a manner that would infringe the patent if such combination occurred within the United States, shall be liable as an infringer.

(g) Whoever without authority imports into the United States or sells or uses within the United States a product which is made by a process patented in the United States shall be liable as an infringer, if the importation, sale, or use of the product occurs during the term of such process patent. In an action for infringement of a process patent, no remedy may be granted for infringement on account of the noncommercial use or retail sale of a product unless there is no adequate remedy under this title for infringement on account of the importation or other use or sale of that product. A product which is made by a patented process will, for purposes of this title, not be considered to be so made after—

(1) it is materially changed by subsequent processes; or

(2) it becomes a trivial and nonessential component of another product.

(h) As used in this section, the term “whoever” includes any State, any instrumentality of a State, and any officer or employee of a State or instrumentality of a State acting in his official capacity. Any State, and any such instrumentality, officer, or employee, shall be subject to the provisions of this title in the same manner and to the same extent as any nongovernmental entity.

L. 103–465, title V, §§533(a), 534(a), (b)(3), Dec. 8, 1994, 108 Stat. 4988, 4990, provided that, effective on date that is one year after date on which the WTO Agreement enters into force with respect to the United States [Jan. 1, 1995], with provisions relating to earliest filed patent application, this section is amended:

(1) in subsection (a)—

(A) by inserting “, offers to sell,” after “uses”; and

(B) by inserting “or imports into the United States any patented invention” after “the United States”;

(2) in subsection (c), by striking “sells” and inserting “offers to sell or sells within the United States or imports into the United States”;

(3) in subsection (e)—

(A) in paragraph (1), by striking “or sell” and inserting “offer to sell, or sell within the United States or import into the United States”;

(B) in paragraph (3), by striking “or selling” and inserting “offering to sell, or selling within the United States or importing into the United States”;

(C) in paragraph (4)(B), by striking “or sale” and inserting “offer to sell, or sale within the United States or importation into the United States”; and

(D) in paragraph (4)(C), by striking “or sale” and inserting “offer to sell, or sale within the United States or importation into the United States”;

(B) by striking “importation, sale,” and inserting “importation, offer to sell, sale,”; and

(C) by striking “other use or” and inserting “other use, offer to sell, or”; and

(5) by adding at the end the following:

(i) As used in this section, an “offer for sale” or an “offer to sell” by a person other than the patentee, or any designee of the patentee, is that in which the sale will occur before the expiration of the term of the patent.

The first paragraph of this section is declaratory only, defining infringement.

Paragraphs (b) and (c) define and limit contributory infringement of a patent and paragraph (d) is ancillary to these paragraphs, see preliminary general description of bill. One who actively induces infringement as by aiding and abetting the same is liable as an infringer, and so is one who sells a component part of a patented invention or material or apparatus for use therein knowing the same to be especially made or especially adapted for use in the infringement of the patent except in the case of a staple article or commodity of commerce having other uses. A patentee is not deemed to have misused his patent solely by reason of doing anything authorized by the section.

This section is referred to in section 157 of this title.

A patent shall be presumed valid. Each claim of a patent (whether in independent, dependent, or multiple dependent form) shall be presumed valid independently of the validity of other claims; dependent or multiple dependent claims shall be presumed valid even though dependent upon an invalid claim. The burden of establishing invalidity of a patent or any claim thereof shall rest on the party asserting such invalidity.

The following shall be defenses in any action involving the validity or infringement of a patent and shall be pleaded:

(1) Noninfringement, absence of liability for infringement or unenforceability,

(2) Invalidity of the patent or any claim in suit on any ground specified in part II of this title as a condition for patentability,

(3) Invalidity of the patent or any claim in suit for failure to comply with any requirement of sections 112 or 251 of this title,

(4) Any other fact or act made a defense by this title.

In actions involving the validity or infringement of a patent the party asserting invalidity or noninfringement shall give notice in the pleadings or otherwise in writing to the adverse party at least thirty days before the trial, of the country, number, date, and name of the patentee of any patent, the title, date, and page numbers of any publication to be relied upon as anticipation of the patent in suit or, except in actions in the United States Court of Federal Claims, as showing the state of the art, and the name and address of any person who may be relied upon as the prior inventor or as having prior knowledge of or as having previously used or offered for sale the invention of the patent in suit. In the absence of such notice proof of the said matters may not be made at the trial except on such terms as the court requires. Invalidity of the extension of a patent term or any portion thereof under section 156 of this title because of the material failure—

(1) by the applicant for the extension, or

(2) by the Commissioner,

to comply with the requirements of such section shall be a defense in any action involving the infringement of a patent during the period of the extension of its term and shall be pleaded. A due diligence determination under section 156(d)(2) is not subject to review in such an action.

(July 19, 1952, ch. 950, 66 Stat. 812; July 24, 1965, Pub. L. 89–83, §10, 79 Stat. 261; Nov. 14, 1975, Pub. L. 94–131, §10, 89 Stat. 692; Apr. 2, 1982, Pub.

The first paragraph declares the existing presumption of validity of patents.

The five defenses named in R.S. 4920 are omitted and replaced by a broader paragraph specifying defenses in general terms.

The third paragraph, relating to notice of prior patents, publications and uses, is based on part of the last paragraph of R.S. 4920 which was superseded by the Federal Rules of Civil Procedure but which is reinstated with modifications.

L. 98–417 inserted provision at end that the invalidity of the extension of a patent term or any portion thereof under section 156 of this title because of the material failure by the applicant for the extension, or by the Commissioner, to comply with the requirements of such section shall be a defense in any action involving the infringement of a patent during the period of the extension of its term and shall be pleaded, and that a due diligence determination under section 156(d)(2) is not subject to review in such an action.

1982—Third par. Pub. L. 97–164 substituted “Claims Court” for “Court of Claims”.

1975—First par. Pub. L. 94–131 made presumption of validity applicable to claim of a patent in multiple dependent form and multiple dependent claims and substituted “asserting such invalidity” for “asserting it”.

This section is referred to in sections 154, 157, 271, 296 of this title.

Except as otherwise provided by law, no recovery shall be had for any infringement committed more than six years prior to the filing of the complaint or counterclaim for infringement in the action.

In the case of claims against the United States Government for use of a patented invention, the period before bringing suit, up to six years, between the date of receipt of a written claim for compensation by the department or agency of the Government having authority to settle such claim, and the date of mailing by the Government of a notice to the claimant that his claim has been denied shall not be counted as part of the period referred to in the preceding paragraph.

(July 19, 1952, ch. 950, 66 Stat. 813.)

Based on Title 35, U.S.C., 1946 ed., §70, part (R.S. 4921, amended (1) Mar. 3, 1897, ch. 391, §6, 29 Stat. 694, (2) Feb. 18, 1922, ch. 58, §8, 42 Stat. 392, (3) Aug. 1, 1946, ch. 726, §1, 60 Stat. 778).

The first paragraph is the same as the provision in R.S. 4921 with minor changes in language, with the added provision relating to the date for counterclaims for infringement.

The second paragraph is new and relates to extending the period of limitations with respect to suits in the Court of Claims in certain instances when administrative consideration is pending.

This section is referred to in section 157 of this title.

(a) Patentees, and persons making or selling any patented article for or under them, may give notice to the public that the same is patented, either by fixing thereon the word “patent” or the abbreviation “pat.”, together with the number of the patent, or when, from the character of the article, this can not be done, by fixing to it, or to the package wherein one or more of them is contained, a label containing a like notice. In the event of failure so to mark, no damages shall be recovered by the patentee in any action for infringement, except on proof that the infringer was notified of the infringement and continued to infringe thereafter, in which event damages may be recovered only for infringement occurring after such notice. Filing of an action for infringement shall constitute such notice.

(b)(1) An infringer under section 271(g) shall be subject to all the provisions of this title relating to damages and injunctions except to the extent those remedies are modified by this subsection or section 9006 of the Process Patent Amendments Act of 1988. The modifications of remedies provided in this subsection shall not be available to any person who—

(A) practiced the patented process;

(B) owns or controls, or is owned or controlled by, the person who practiced the patented process; or

(C) had knowledge before the infringement that a patented process was used to make the product the importation, use, or sale of which constitutes the infringement.

(2) No remedies for infringement under section 271(g) of this title shall be available with respect to any product in the possession of, or in transit to, the person subject to liability under such section before that person had notice of infringement with respect to that product. The person subject to liability shall bear the burden of proving any such possession or transit.

(3)(A) In making a determination with respect to the remedy in an action brought for infringement under section 271(g), the court shall consider—

(i) the good faith demonstrated by the defendant with respect to a request for disclosure,

(ii) the good faith demonstrated by the plaintiff with respect to a request for disclosure, and

(iii) the need to restore the exclusive rights secured by the patent.

(B) For purposes of subparagraph (A), the following are evidence of good faith:

(i) a request for disclosure made by the defendant;

(ii) a response within a reasonable time by the person receiving the request for disclosure; and

(iii) the submission of the response by the defendant to the manufacturer, or if the manufacturer is not known, to the supplier, of the product to be purchased by the defendant, together with a request for a written statement that the process claimed in any patent disclosed in the response is not used to produce such product.

The failure to perform any acts described in the preceding sentence is evidence of absence of good faith unless there are mitigating circumstances. Mitigating circumstances include the case in which, due to the nature of the product, the number of sources for the product, or like commercial circumstances, a request for disclosure is not necessary or practicable to avoid infringement.

(4)(A) For purposes of this subsection, a “request for disclosure” means a written request made to a person then engaged in the manufacture of a product to identify all process patents owned by or licensed to that person, as of the time of the request, that the person then reasonably believes could be asserted to be infringed under section 271(g) if that product were imported into, or sold or used in, the United States by an unauthorized person. A request for disclosure is further limited to a request—

(i) which is made by a person regularly engaged in the United States in the sale of the same type of products as those manufactured by the person to whom the request is directed, or which includes facts showing that the person making the request plans to engage in the sale of such products in the United States;

(ii) which is made by such person before the person's first importation, use, or sale of units of the product produced by an infringing process and before the person had notice of infringement with respect to the product; and

(iii) which includes a representation by the person making the request that such person will promptly submit the patents identified pursuant to the request to the manufacturer, or if the manufacturer is not known, to the supplier, of the product to be purchased by the person making the request, and will request from that manufacturer or supplier a written statement that none of the processes claimed in those patents is used in the manufacture of the product.

(B) In the case of a request for disclosure received by a person to whom a patent is licensed, that person shall either identify the patent or promptly notify the licensor of the request for disclosure.

(C) A person who has marked, in the manner prescribed by subsection (a), the number of the process patent on all products made by the patented process which have been sold by that person in the United States before a request for disclosure is received is not required to respond to the request for disclosure. For purposes of the preceding sentence, the term “all products” does not include products made before the effective date of the Process Patent Amendments Act of 1988.

(5)(A) For purposes of this subsection, notice of infringement means actual knowledge, or receipt by a person of a written notification, or a combination thereof, of information sufficient to persuade a reasonable person that it is likely that a product was made by a process patented in the United States.

(B) A written notification from the patent holder charging a person with infringement shall specify the patented process alleged to have been used and the reasons for a good faith belief that such process was used. The patent holder shall include in the notification such information as is reasonably necessary to explain fairly the patent holder's belief, except that the patent holder is not required to disclose any trade secret information.

(C) A person who receives a written notification described in subparagraph (B) or a written response to a request for disclosure described in paragraph (4) shall be deemed to have notice of infringement with respect to any patent referred to in such written notification or response unless that person, absent mitigating circumstances—

(i) promptly transmits the written notification or response to the manufacturer or, if the manufacturer is not known, to the supplier, of the product purchased or to be purchased by that person; and

(ii) receives a written statement from the manufacturer or supplier which on its face sets forth a well grounded factual basis for a belief that the identified patents are not infringed.

(D) For purposes of this subsection, a person who obtains a product made by a process patented in the United States in a quantity which is abnormally large in relation to the volume of business of such person or an efficient inventory level shall be rebuttably presumed to have actual knowledge that the product was made by such patented process.

(6) A person who receives a response to a request for disclosure under this subsection shall pay to the person to whom the request was made a reasonable fee to cover actual costs incurred in complying with the request, which may not exceed the cost of a commercially available automated patent search of the matter involved, but in no case more than $500.

Whenever, without deceptive intention, a claim of a patent is invalid, an action may be maintained for the infringement of a claim of the patent which may be valid. The patentee shall recover no costs unless a disclaimer of the invalid claim has been entered at the Patent and Trademark Office before the commencement of the suit.

(July 19, 1952, ch. 950, 66 Stat. 813; Jan. 2, 1975, Pub. L. 93–596, §1, 88 Stat. 1949.)

Amendment by Pub. L. 93–596 effective Jan. 2, 1975, see section 4 of Pub. L. 93–596, set out as a note under section 1111 of Title 15, Commerce and Trade.

(a) A contract involving a patent or any right under a patent may contain a provision requiring arbitration of any dispute relating to patent validity or infringement arising under the contract. In the absence of such a provision, the parties to an existing patent validity or infringement dispute may agree in writing to settle such dispute by arbitration. Any such provision or agreement shall be valid, irrevocable, and enforceable, except for any grounds that exist at law or in equity for revocation of a contract.

(b) Arbitration of such disputes, awards by arbitrators and confirmation of awards shall be governed by title 9, United States Code, to the extent such title is not inconsistent with this section. In any such arbitration proceeding, the defenses provided for under section 282 of this title shall be considered by the arbitrator if raised by any party to the proceeding.

(c) An award by an arbitrator shall be final and binding between the parties to the arbitration but shall have no force or effect on any other person. The parties to an arbitration may agree that in the event a patent which is the subject matter of an award is subsequently determined to be invalid or unenforceable in a judgment rendered by a court to 1 competent jurisdiction from which no appeal can or has been taken, such award may be modified by any court of competent jurisdiction upon application by any party to the arbitration. Any such modification shall govern the rights and obligations between such parties from the date of such modification.

(d) When an award is made by an arbitrator, the patentee, his assignee or licensee shall give notice thereof in writing to the Commissioner. There shall be a separate notice prepared for each patent involved in such proceeding. Such notice shall set forth the names and addresses of the parties, the name of the inventor, and the name of the patent owner, shall designate the number of the patent, and shall contain a copy of the award. If an award is modified by a court, the party requesting such modification shall give notice of such modification to the Commissioner. The Commissioner shall, upon receipt of either notice, enter the same in the record of the prosecution of such patent. If the required notice is not filed with the Commissioner, any party to the proceeding may provide such notice to the Commissioner.

(e) The award shall be unenforceable until the notice required by subsection (d) is received by the Commissioner.

1 So in original. Probably should be “of”.

In actions alleging infringement of a process patent based on the importation, sale, or use of a product which is made from a process patented in the United States, if the court finds—

(1) that a substantial likelihood exists that the product was made by the patented process, and

(2) that the plaintiff has made a reasonable effort to determine the process actually used in the production of the product and was unable to so determine,

the product shall be presumed to have been so made, and the burden of establishing that the product was not made by the process shall be on the party asserting that it was not so made.

(b) A record of the Commissioner's determination under subsection (a) of this section will be placed in the official file of the patent, and a copy promptly will be given or mailed to the owner of record of the patent and to the person requesting reexamination, if any.

(c) A determination by the Commissioner pursuant to subsection (a) of this section that no substantial new question of patentability has been raised will be final and nonappealable.

If, in a determination made under the provisions of subsection 303(a) of this title, the Commissioner finds that a substantial new question of patentability affecting any claim of a patent is raised, the determination will include an order for reexamination of the patent for resolution of the question. The patent owner will be given a reasonable period, not less than two months from the date a copy of the determination is given or mailed to him, within which he may file a statement on such question, including any amendment to his patent and new claim or claims he may wish to propose, for consideration in the reexamination. If the patent owner files such a statement, he promptly will serve a copy of it on the person who has requested reexamination under the provisions of section 302 of this title. Within a period of two months from the date of service, that person may file and have considered in the reexamination a reply to any statement filed by the patent owner. That person promptly will serve on the patent owner a copy of any reply filed.

(Added Pub. L. 96–517, §1, Dec. 12, 1980, 94 Stat. 3016.)

No proposed amended or new claim enlarging the scope of a claim of the patent will be permitted in a reexamination proceeding under this chapter. All reexamination proceedings under this section, including any appeal to the Board of Patent Appeals and Interferences, will be conducted with special dispatch within the Office.

Chapter 38, as added by Pub. L. 96–517, §6(a), Dec. 12, 1980, 94 Stat. 3018, was originally editorially inserted after chapter 17 of this title because the probable intent of Congress was to designate the chapter as “18”, in view of the numerical designation of the sections contained in the chapter as sections 200 to 211 and in view of the subject matter of the chapter in relation to the subject matter of Part II of this title. Pub. L. 97–256, title I, §101(5), Sept. 8, 1982, 96 Stat. 816, redesignated chapter 38 as chapter 18 and transferred chapter 18, as so redesignated, from the end of this part to the end of Part II. See 1982 Amendment note set out under the analysis of chapter 18 (§200 et seq.) of this title.
