37 CFR Part 1

[Docket No. PTO-P-2025-0008]
RIN 0651-AD85


Required Use by Foreign Applicants and Patent Owners of a Patent 
Practitioner

AGENCY: United States Patent and Trademark Office, Commerce.

ACTION: Notice of proposed rulemaking.

-----------------------------------------------------------------------

SUMMARY: The United States Patent and Trademark Office (USPTO or 
Office) is proposing to amend the Rules of Practice in Patent Cases to 
require patent applicants and patent owners whose domicile is not 
located within the United States (U.S.) or its territories (hereinafter 
foreign applicants/inventors and patent owners) to be represented by a 
registered patent practitioner. A requirement that foreign applicants/
inventors and patent owners be represented by a registered patent 
practitioner would bring the United States in line with most other 
countries that require that such parties be represented by a licensed 
or registered person of that country. Additionally, this requirement 
would increase efficiency and enable the USPTO to more effectively use 
available mechanisms to enforce compliance by all foreign applicants/
inventors and patent owners with U.S. statutory and regulatory 
requirements in patent matters, and enhance the USPTO's ability to 
respond to false certifications, misrepresentations, and fraud.

DATES: Comments must be received by January 28, 2026 to ensure 
consideration.

ADDRESSES: For reasons of government efficiency, comments must be 
submitted through the Federal eRulemaking Portal at 
www.regulations.gov. To submit comments via the portal, one should 
enter docket number PTO-P-2025-0008 on the homepage and select 
``Search.'' The site will provide search results listing all documents 
associated with this docket. Commenters can find a reference to this 
proposed rule and select the ``Comment'' icon, complete the required 
fields, and enter or attach their comments. Attachments to electronic 
comments will be accepted in Adobe[supreg] portable document format 
(PDF) or Microsoft Word[supreg] format. Because comments will be made 
available for public inspection, information that the submitter does 
not desire to make public, such as an address or phone number, should 
not be included in the comments.
    Visit the Federal eRulemaking Portal for additional instructions on 
providing comments via the portal. If electronic submission of or 
access to comments is not feasible due to a lack of access to a 
computer and/or the internet, please contact the USPTO using the 
contact information below for special instructions.

SUPPLEMENTARY INFORMATION:

I. Background

    Pursuant to its authority under 35 U.S.C. 2(b)(2), the USPTO is 
proposing to revise the rules in part 1 of title 37 of the Code of 
Federal Regulations to require foreign applicants/inventors and patent 
owners to be represented by a registered patent practitioner, as 
defined in 37 CFR 1.32(a)(1) (i.e., a registered patent attorney or 
registered patent agent under 37 CFR 11.6 or an individual given 
limited recognition under Sec.  11.9(a) or (b) or Sec.  11.16) 
(hereinafter, registered patent practitioner). Requiring all foreign 
applicants/inventors and patent owners to be represented by a 
registered patent practitioner (1) treats foreign applicants/inventors 
and patent owners similarly to how U.S. applicants/inventors and patent 
owners are treated in other countries and harmonizes U.S. practice with 
the rest of the world; (2) increases efficiency as the USPTO spends 
extra resources to handle pro se applicants (i.e., an applicant who is 
prosecuting the application without a registered patent practitioner); 
(3) enables the USPTO to more effectively use available mechanisms to 
enforce compliance with statutory and regulatory requirements in patent 
matters; and (4) enhances the USPTO's ability to respond to false 
certifications, misrepresentations, and fraud.

A. Harmonization of U.S. Practice With Other Intellectual Property (IP) 
Offices With Respect to Representation

    Almost all IP Offices require foreign applicants/inventors and 
patent owners to be represented by a person licensed or registered in 
that country. The USPTO is proposing to implement a similar 
requirement. Requiring foreign applicants/inventors and patent owners 
to be represented by a registered patent practitioner would help to 
harmonize patent filing practice across IP Offices.

B. Increase Efficiency

    The USPTO utilizes extra resources to assist pro se inventors. 
Requiring foreign applicants/inventors and patent owners to use 
registered patent practitioners will increase efficiency, as the 
applications will be in better form for examination. Applications from 
pro se inventors generally require additional processing by the Office 
of Patent Application Processing because the application papers are 
often not in condition for publication, examination, or both. 
Additionally, pro se applications usually require patent examiners to 
spend examination time on procedural matters, thereby increasing 
overall patent application pendency. Implementing this proposed rule 
would help allocate USPTO resources to the merits of examination and, 
accordingly, decrease patent application processing times.

C. Enforce Compliance With U.S. Statutory and Regulatory Requirements

    The requirement for representation by a registered patent 
practitioner is also necessary to enforce compliance by all foreign 
patent applicants/inventors and patent owners with U.S. statutory and 
regulatory requirements in patent matters. Registered patent 
practitioners are subject to the USPTO Rules of Professional Conduct 
and disciplinary sanctions for violations of those rules. See 37 CFR 
11.15, 11.20, and 11.100-11.901. Accordingly, registered patent 
practitioners have various obligations to the USPTO, including a duty 
to cooperate with inquiries and investigations. See, e.g., 37 CFR 
11.303 and 11.801.
    The USPTO has noticed an increase in the number of false micro 
entity certifications to claim a reduction in fees and other false 
certification documents being filed. False certifications unjustly 
diminish the monetary resources of the USPTO, and false certifications 
on petitions or requests to expedite examination result in applications 
being unjustly advanced out of turn. Requiring submissions to be

[[Page 60595]]

made by registered patent practitioners subject to the USPTO Rules of 
Professional Conduct and concomitant disciplinary sanctions imposed by 
the USPTO Director will make it less likely that the submissions will 
be signed by an unauthorized party or contain inaccurate or fraudulent 
statements, particularly with regard to any certification of micro 
entity status to claim a reduction in fees and any certification 
relevant to expediting the application.

D. Fraud Mitigation and the Integrity of the U.S. Patent System

    Requiring foreign patent applicants/inventors and patent owners to 
use registered patent practitioners will also facilitate fraud 
mitigation and protect the integrity of the U.S. patent system. As 
discussed, registered patent practitioners have a duty to cooperate 
with investigations and respond to lawful requests for information. See 
37 CFR 11.801(b). Further, it is professional misconduct for a 
registered patent practitioner to engage in conduct involving 
dishonesty, fraud, deceit, or misrepresentation. See 37 CFR 11.804(c). 
It is also professional misconduct for a registered patent practitioner 
to engage in conduct that is prejudicial to the administration of 
justice. See 37 CFR 11.804(d). Because registered patent practitioners 
are subject to disciplinary sanctions pursuant to 37 CFR 11.15 and 
11.20, they have an interest in responding to inquiries and 
investigations that extends beyond the outcome of a particular 
application.
    For example, the USPTO currently sends fee deficiency notices in 
applications which appear to have false micro entity certifications, 
and can also send requests for information or show cause orders in 
applications in which an apparent misrepresentation has been made. In 
patent applications with pro se inventor-applicants, abandonment of the 
application effectively terminates the USPTO's ability to gather 
information. If a subsequent application is filed on the same subject 
matter, it may be difficult or impossible for the USPTO to establish 
that the applications are commonly owned or otherwise attributable to 
the same parties. However, when a registered patent practitioner is of 
record in the application or files papers in the application, the 
ability of the USPTO to gather information about the certifications or 
representations that were made extends beyond abandonment of the 
application. Therefore, requiring foreign patent applicants/inventors 
and patent owners to use registered patent practitioners would 
facilitate fraud mitigation and protect the integrity of the U.S. 
patent system.

II. Enforcement

    Unsigned or improperly signed papers are not entered into the 
record of the application or patent. See, e.g., MPEP 714.01. As such, 
when representation by a registered patent practitioner is required, 
papers such as amendments and other replies, application data sheets, 
information disclosure statements, or petitions, would not be entered 
unless they are signed by a registered patent practitioner. This would 
not apply to papers which are required to be signed by a specific 
party, such as the inventor's oath or declaration under 37 CFR 1.63.
    The definition of the term ``domicile'' is provided in proposed 37 
CFR 1.9(p). The domicile of an inventor-applicant will normally be 
determined by the residence information provided in the application 
data sheet (ADS) under 37 CFR 1.76, or the inventor's oath or 
declaration under 37 CFR 1.63 (including a substitute statement under 
37 CFR 1.64). The domicile of an applicant who is not an inventor will 
normally be determined based on the mailing address provided in the 
Applicant Information section of the ADS. If an ADS is inconsistent 
with the information provided in another document that was submitted at 
the same time or prior to the ADS submission, the ADS will control. See 
37 CFR 1.76(d). This is because the ADS is intended to be the means by 
which an applicant provides complete bibliographic information. In some 
instances, the USPTO may refer to sources other than those listed above 
for purposes of assessing compliance with the domicile requirement. For 
example, in order to determine whether the domicile is accurate, the 
USPTO may refer to the notarized Patent Electronic System Verification 
form or other identity verification information.
    A paper filed on behalf of the patent owner may indicate the 
domicile of the patent owner if such information is not present in the 
application file. When it is necessary for the USPTO to act on a paper 
submitted in the file of an issued patent and the paper is not signed 
by a registered patent practitioner, the paper may not be treated on 
its merits. For example, if a petition to accept unintentionally 
delayed payment of a maintenance fee in an expired patent under 37 CFR 
1.378(b) is filed that is not signed by a registered patent 
practitioner, the petition may be dismissed before consideration on the 
merits if it cannot be determined whether the paper complies with 37 
CFR 1.31 and 1.33(b).
    Regarding the assessment of compliance referred to above, 
applicants, patent owners, and practitioners are reminded that the 
presentation to the Office of any paper by a party, whether a 
practitioner or non-practitioner, constitutes a certification under 37 
CFR 11.18(b). A misrepresentation of the domicile of an applicant or 
patent owner would not be ``to the best of the party's knowledge, 
information and belief, formed after an inquiry reasonable under the 
circumstances'' as required under 37 CFR 11.18(b)(2). Violations of 37 
CFR 11.18(b)(2) by a party, whether a practitioner or non-practitioner, 
may result in the imposition of sanctions under 37 CFR 11.18(c), which 
may include termination of the proceedings. See 37 CFR 1.4(d)(5)(i).

III. Discussion of Specific Rules

    The following is a discussion of proposed amendments to 37 CFR part 
1:

A. Section 1.9

    Section 1.9 is proposed to be amended to add new paragraph (p) 
defining domicile as the permanent legal place of residence of a 
natural person or the principal place of business of a juristic entity. 
The domicile of an inventor-applicant will normally be determined by 
the residence information provided in the ADS under 37 CFR 1.76, or the 
inventor's oath or declaration under 37 CFR 1.63 (including a 
substitute statement under 37 CFR 1.64). The domicile of an applicant 
who is not an inventor will normally be determined based on the mailing 
address provided in the Applicant Information section of the ADS. See 
section II. above for further discussion.

B. Section 1.31

    Section 1.31 is proposed to be amended to add the title and rule to 
include ``patent owner,'' and reformatting the rule language into 
paragraphs (a) and (b). The section is further proposed to be amended 
to indicate that an applicant as defined in Sec.  1.42 or patent owner 
whose domicile is not located within the U.S. or its territories must 
be represented by a registered patent practitioner. The section is also 
proposed to be amended to require that a patent owner who is a juristic 
entity must be represented by a registered patent practitioner. The 
section previously required a juristic entity who was the applicant to 
be represented by a registered patent

[[Page 60596]]

practitioner, but has now been expanded to make a similar requirement 
for patent owners in post-grant proceedings.
    The phrase ``an applicant as defined in Sec.  1.42'' in paragraph 
(a) encompasses any inventor, joint inventor, legal representative, 
person to whom the inventor has assigned, person to whom the inventor 
is under an obligation to assign, or person who otherwise shows 
sufficient proprietary interest in the matter who is named as an 
applicant. Thus, an applicant as defined in Sec.  1.42 must be 
represented by a registered patent practitioner if at least one of the 
parties identified as the applicant has a domicile that is not located 
within the U.S. or its territories. See Sec.  1.31(a)(2). As a 
reminder, powers of attorney must be signed by all parties identified 
as the applicant in order to be effective.

C. Section 1.32

    Section 1.32 is proposed to be amended to add the definition of 
patent practitioner to partially parallel Sec.  11.10(a).

D. Section 1.33

    Section 1.33 is proposed to be amended to add paragraph (b)(3) to 
indicate that for amendments and other papers filed in an application 
or patent unless otherwise specified submitted on behalf of a juristic 
entity, an applicant as defined in Sec.  1.42 whose domicile is not 
located within the United States or its territories, or a patent owner 
whose domicile is not located within the United States or its 
territories must be signed by a patent practitioner. These revisions to 
paragraph (b)(3) are consistent with the changes to Sec.  1.31, 
discussed above.
    A foreign domiciled inventor who is the applicant may initially 
file a U.S. patent application with the USPTO and pay the filing fee at 
the time of filing. However, any application data sheet that 
accompanies the application papers or is submitted later, as well as 
all follow-on correspondence, must be signed by a patent practitioner. 
A patent practitioner must also sign any petition that is filed in such 
an application, including but not limited to a request for prioritized 
examination and a petition to make special. To pay the issue fee, PTOL-
85 Part B would also have to be signed by a patent practitioner.

IV. Rulemaking Considerations

A. Administrative Procedure Act

    This rulemaking would revise the procedures governing the 
representation of patent applicants and patent owners at the USPTO. The 
proposed changes do not change the substantive criteria of 
patentability. Therefore, the changes in this rulemaking involve rules 
of agency practice and procedure and/or interpretive rules and do not 
require notice-and-comment rulemaking, pursuant to 5 U.S.C. 553(b)(A)). 
See Perez v. Mortg. Bankers Ass'n, 575 U.S. 92, 97, 101 (2015) 
(explaining that interpretive rules ``advise the public of the agency's 
construction of the statutes and rules which it administers'' and do 
not require notice-and-comment when issued or amended); Cooper Techs. 
Co. v. Dudas, 536 F.3d 1330, 1336-37 (Fed. Cir. 2008) (5 U.S.C. 553, 
and thus 35 U.S.C. 2(b)(2)(B), do not require notice-and-comment 
rulemaking for ``interpretative rules, general statements of policy, or 
rules of agency organization, procedure, or practice''); In re Chestek 
PLLC, 92 F.4th 1105, 1110 (Fed. Cir. 2024) (noting that rule changes 
that ``do[ ] not alter the substantive standards by which the USPTO 
evaluates trademark applications'' are procedural in nature and thus 
``exempted from notice-and-comment rulemaking.''); and JEM Broadcasting 
Co. v. F.C.C., 22 F.3d 320, 328 (D.C. Cir. 1994) (``[T]he `critical 
feature' of the procedural exception [in 5 U.S.C. 553(b)(A)] `is that 
it covers agency actions that do not themselves alter the rights or 
interests of parties, although [they] may alter the manner in which the 
parties present themselves or their viewpoints to the agency.' '' 
(quoting Batterton v. Marshall, 648 F.2d 694, 707 (D.C. Cir. 1980))). 
However, the USPTO has chosen to seek public comment before 
implementing the rule to benefit from the public's input.

B. Regulatory Flexibility Act

    As prior notice and an opportunity for public comment are not 
required pursuant to 5 U.S.C. 553 or any other law, neither a 
Regulatory Flexibility Act analysis nor a certification under the 
Regulatory Flexibility Act (5 U.S.C. 601, et seq.) is required. See 5 
U.S.C. 603. Nevertheless, the USPTO publishes this IRFA to examine the 
impact on small entities of the Office's proposed requirement that 
patent applicants and patent owners whose domicile is not located 
within the United States (U.S.) or its territories (hereinafter 
``foreign applicants/inventors and patent owners'') be represented by a 
registered patent practitioner, as defined in 37 CFR 1.32(a)(1), and to 
seek the public's views. The USPTO developed this IRFA to promote 
transparency and to inform the public of the impacts of this rule. The 
term domicile is defined as the permanent legal place of residence of a 
natural person or the principal place of business of a juristic entity, 
as provided in new paragraph (p) under 37 CFR 1.9 of this proposed 
rule. Items 1-5 below discuss the five items specified in 5 U.S.C. 
603(b)(1)-(5) to be addressed in an IRFA. Item 6 below discusses any 
alternatives to this proposal that the Office considered under 5 U.S.C. 
603(c).
1. Description of the Reasons That Action by the USPTO Is Being 
Considered
    The USPTO proposes to require that foreign applicants/inventors and 
patent owners be represented by a registered patent practitioner, as 
defined in proposed 37 CFR 1.32(a)(1). An ``applicant'' is the person 
applying for a patent, and can be any inventor, joint inventor, legal 
representative, person to whom the inventor has assigned, person to 
whom the inventor is under an obligation to assign, or person who 
otherwise shows sufficient proprietary interest in the matter who is 
named as an applicant. Under this proposed rule, foreign applicants/
inventors and patent owners must be represented by a registered patent 
practitioner if at least one of the parties identified as an applicant 
or a patent owner has a domicile that is not located within the U.S. or 
its territories. A patent practitioner as defined in proposed 37 CFR 
1.32(a)(1) means a registered patent attorney or registered patent 
agent under 37 CFR 11.6 or an individual given limited recognition 
under Sec.  11.9(a) or (b) or Sec.  11.16. When representation by a 
registered patent practitioner is required, papers such as amendments 
and other replies, application data sheets, information disclosure 
statements, or petitions, will not be entered unless they are signed by 
a registered patent practitioner; papers which are required to be 
signed by a specific party, such as the inventor's oath or declaration 
under 37 CFR 1.63, are excluded. The requirement for a registered 
patent practitioner is applicable to all applications types (i.e., 
utility, plant, design, etc.). This proposed rule would bring the 
United States in line with most other countries that require that such 
parties be represented by a licensed or registered person of that 
country. Additionally, this proposed rule would increase efficiency and 
enable the USPTO to more effectively use available mechanisms to 
enforce compliance by all foreign applicants/inventors and patent 
owners with U.S. statutory and regulatory requirements in patent 
matters, and enhance the USPTO's ability to respond to false 
certifications, misrepresentations, and fraud. The rule

[[Page 60597]]

is also amended to require that a patent owner who is a juristic entity 
must be represented by a registered patent practitioner. The rule 
previously required a juristic entity who was the applicant to be 
represented by a registered patent practitioner, and has now been 
expanded to make explicit a similar requirement for patent owners in 
post-grant proceedings.
2. Succinct Statement of the Objectives of, and Legal Basis for, the 
Proposed Rule
    The USPTO undertakes this proposed rule pursuant to its authority 
under 35 U.S.C. 2(b)(2), which authorizes the USPTO Director to 
establish regulations, not inconsistent with law, governing the conduct 
of proceedings in the Office. The policy objectives of the proposed 
rule are to: (1) treat foreign applicants/inventors and patent owners 
similarly to how U.S. applicants/inventors and patent owners are 
treated in other countries and harmonize U.S. practice with the rest of 
the world; (2) increase efficiency by reducing the extra resources the 
USPTO spends to handle pro se applicants (i.e., an applicant who is 
prosecuting the application without a registered patent practitioner); 
(3) enable the USPTO to more effectively use available mechanisms to 
enforce compliance with statutory and regulatory requirements in patent 
matters; and (4) enhance the USPTO's ability to respond to false 
certifications, misrepresentations, and fraud.
3. Description of and, Where Feasible, an Estimate of the Number of 
Small Entities to Which the Proposed Rule Will Apply
    The Small Business Administration (SBA) small business size 
standards that are applicable to most analyses conducted to comply with 
the RFA are set forth in 13 CFR 121.201. These regulations generally 
define small businesses as those with fewer than a specified maximum 
number of employees or less than a specified level of annual receipts 
for the entity's industrial sector or North American Industry 
Classification System (NAICS) code. As provided by the RFA, and after 
consulting with the SBA, the USPTO formally adopted an alternate size 
standard for the purpose of conducting an analysis or making a 
certification under the RFA for patent-related regulations. See 
Business Size Standard for Purposes of United States Patent and 
Trademark Office Regulatory Flexibility Analysis for Patent-Related 
Regulations, 71 FR 67109 (Nov. 20, 2006), 1313 Off. Gaz. Pat. Office 60 
(Dec. 12, 2006). The USPTO's alternate small business size standard is 
SBA's previously established size standard that identifies the criteria 
entities must meet to be entitled to pay reduced patent fees. See 13 
CFR 121.802.
    If patent applicants assert or certify entitlement for reduced 
patent fees, the USPTO captures this data in its patent application 
data repository (formerly the Patent Application Locating and 
Monitoring (PALM) system and now called the One Patent Service Gateway 
(OPSG) system), which tracks information on each patent application 
submitted to the Office.
    Unlike the SBA small business size standards set forth in 13 CFR 
121.201, the size standard for the USPTO is not industry specific. The 
Office's definition of a small business concern for RFA purposes is a 
business or other concern that: (1) meets the SBA's definition of a 
``business concern or concern'' set forth in 13 CFR 121.105; and (2) 
meets the size standards set forth in 13 CFR 121.802 for the purpose of 
paying reduced patent fees, namely, an entity: (a) whose number of 
employees, including affiliates, does not exceed 500 persons; and (b) 
which has not assigned, granted, conveyed, or licensed (and is under no 
obligation to do so) any rights in the invention to any person who made 
it and could not be classified as an independent inventor, or to any 
concern that would not qualify as a nonprofit organization or a small 
business concern under this definition. See Business Size Standard for 
Purposes of United States Patent and Trademark Office Regulatory 
Flexibility Analysis for Patent-Related Regulations, 71 FR at 67112 
(Nov. 20, 2006), 1313 Off. Gaz. Pat. Office at 63 (Dec. 12, 2006). 
Thus, for the purpose of this analysis, the USPTO defines small 
entities to include applicants/inventors and patent owners who pay 
``small'' or ``micro'' entity fees at the USPTO.
    In fiscal year (FY) 2022, the USPTO received 512,038 patent 
applications.\1\ As discussed above, this proposed rule would impact 
those applications from foreign applicants/inventors or patent owners 
who are not represented by counsel. An applicant is considered to be a 
foreign applicant/inventor or patent owner if at least one party who 
was identified as an applicant or a patent owner had a domicile that 
was not located within the U.S. or its territories.
---------------------------------------------------------------------------

    \1\ Fiscal year (FY) 2022 data is being used for this analysis 
to correspond with the most current available estimates of legal 
costs as published by American Intellectual Property Law Association 
in its 2023 Report on the Economic Survey. Patent application data 
show that filing trends in FY 2023 and FY 2024 have been consistent 
with FY 2022, with filings in FY 2023 totaling 516,915 and filings 
in FY 2024 totaling 527,538.
---------------------------------------------------------------------------

    As seen in Table 1 below, of the total 512,038 patent applications 
filed in FY 2022, 215,459 (42.1%) were filed by U.S. applicants/
inventors and patent owners, and 296,579 (57.9%) were filed by foreign 
applicants/inventors and patent owners.

  Total.......................................      512,038        100.0
------------------------------------------------------------------------

    Table 2 below shows the number of applications that were filed 
without a registered patent practitioner (i.e., pro se) and those that 
were filed with a registered patent practitioner, in addition to the 
entity status of the applicant(s). Of the total 296,579 filings made by 
a foreign applicant/inventor or patent owner, 295,362 were represented 
by a registered patent practitioner (foreign represented) and 1,217 
were not represented by a registered patent practitioner (foreign pro 
se).\2\ The 1,217 foreign pro se applications would be impacted by the 
requirement to retain representation by a registered patent 
practitioner under this proposed rule.
---------------------------------------------------------------------------

    \2\ An application is determined to be pro se if there are no 
current attorney(s) associated with the application or if no 
attorney(s) has been directly associated with the application over 
the application's prosecution history.
---------------------------------------------------------------------------

    The USPTO anticipates that this proposed rule would not have a 
substantial impact on foreign small entities. Of the total 295,362 
foreign represented applications, 75,111 are considered to be small 
entities for the purposes of this analysis because they paid the 
``small'' or ``micro'' entity fee (foreign represented small entities), 
and of the 1,217 foreign pro se applications, 1,102 are considered to 
be small entities because they paid the ``small'' or ``micro'' entity 
fee (foreign pro se small entities). The USPTO acknowledges that 
representation status in an application is dynamic, and some number of 
applicants change their status of representation after filing by either 
retaining a registered patent practitioner or separating from a 
registered patent practitioner and proceeding pro se. For the purposes 
of this analysis, the USPTO will assume that the 1,102 applications 
filed by foreign pro se small entities did not change their

[[Page 60598]]

representation status and thus would be subject to the requirement to 
be represented by a registered patent practitioner. This proposed rule 
is not expected to significantly impact foreign small entities, as the 
vast majority are represented by a registered patent practitioner. Only 
1,102 foreign pro se small entities, or 1.4% of the 76,213 total 
foreign small entities filing patent applications, would be affected.

                                                                         Table 2

4. Description of the reporting, recordkeeping, and other compliance 
requirements of the proposed rule, including an estimate of the classes 
of small entities which will be subject to the requirement and the type 
of professional skills necessary for preparation of the report or 
record:
    The proposed rule imposes no new reporting or recordkeeping 
requirements. Compliance with the rule will be enforced by requiring an 
appropriate signature on papers submitted in patent matters. Any 
registered patent practitioner retained by the foreign applicants/
inventors and patent owners as a result of this proposed rule would be 
required to be a registered patent attorney or registered patent agent 
under 37 CFR 11.6 or an individual given limited recognition under 
Sec.  11.9(a) or (b) or Sec.  11.16.
5. Identification, to the extent practicable, of all relevant Federal 
rules which may duplicate, overlap or conflict with the proposed rule:
    This proposed rule does not duplicate, overlap, or conflict with 
other Federal rules.
6. Description of any significant alternatives to the proposed rule 
which accomplish the stated objectives of applicable statutes and which 
minimize any significant economic impact of the rule on small entities:
    The USPTO considered one alternative before proposing the 
requirement that foreign applicants/inventors and patent owners be 
represented by a registered patent practitioner, as defined in proposed 
37 CFR 1.32(a)(1). A description of the proposed rule and the one 
alternative follows.
    Proposed Rule: Under the proposed rule, the USPTO proposes to 
require that foreign applicants/inventors and patent owners be 
represented by a registered patent practitioner, as defined in proposed 
37 CFR 1.32(a)(1). An applicant must be represented by a registered 
patent practitioner if at least one of the parties identified as the 
applicant or patent owner has a domicile that is not located within the 
U.S. or its territories. When representation by a registered patent 
practitioner is required, papers such as amendments and other replies, 
application data sheets, information disclosure statements, or 
petitions, will not be entered unless they are signed by a registered 
patent practitioner; papers which are required to be signed by a 
specific party, such as the inventor's oath or declaration under 37 CFR 
1.63, are excluded. The requirement for a registered patent 
practitioner is applicable to all applications types (i.e., utility, 
plant, design, etc.).
    Due to the difficulty in quantifying the intangible benefits 
associated with the proposed rule, the Office provides a discussion of 
the qualitative benefits to patent applicants/inventors and patent 
owners. The primary benefits of the proposed rule are ensuring 
compliance by all foreign patent applicants/inventors and patent owners 
with U.S. statutory and regulatory requirements in patent matters, and 
facilitating fraud mitigation and protecting the integrity of the U.S. 
patent system. The USPTO has noticed an increase in the number of false 
micro entity certifications to claim a reduction in fees and other 
false certification documents being filed. False certifications 
unjustly diminish the monetary resources of the USPTO, and false 
certifications on petitions or requests to expedite examination result 
in applications being unjustly advanced out of turn. Requiring 
submissions to be made by registered patent practitioners subject to 
the USPTO Rules of Professional Conduct and concomitant disciplinary 
sanctions imposed by the USPTO Director will make it less likely that 
the submissions will be signed by an unauthorized party or contain 
inaccurate or fraudulent statements, particularly with regard to any 
certification of micro entity status to claim a reduction in fees and 
any certification relevant to expediting the application.
    The proposed rule also addresses the increasing problem of patent 
application pendency. Pro se applications generally require additional 
processing by the Office of Patent Application Processing because the 
application papers are often not in condition for publication, 
examination, or both. Additionally, pro se applications usually require 
patent examiners to spend examination time on procedural matters, 
thereby increasing overall patent application pendency. This proposed 
rule would help allocate USPTO resources to the merits of examination 
and, accordingly, decrease patent application processing times. 
Requiring foreign applicants/inventors and patent owners to use 
registered patent practitioners will increase efficiency, as the 
applications will be in better form for examination. Thus, the proposed 
rule would provide qualitative value to all applicants/inventors and 
patent owners because this rule would help allocate USPTO resources to 
the merits of examination and, accordingly, generally decrease 
processing times for all patent applications.
    The RFA requires agencies to consider the economic impact of their 
regulatory proposals on small entities, specifically

[[Page 60599]]

U.S. small businesses, small governmental jurisdictions and small 
organizations. This proposed rule would require all applicants/
inventors and patent owners, in which at least one party identified as 
the applicant or patent owner has a foreign domicile, to be represented 
by a registered patent practitioner. Although there will be some number 
of U.S.-domiciled applicants/inventors and patent owners that will be 
affected because at least one party identified as the applicant or 
patent owner has a foreign domicile, the USPTO estimates that the 
number of foreign pro se small entities impacted by this rule (1,102) 
is small when compared to the 76,213 total foreign small entities that 
file patent applications. The costs incurred by the 1,102 foreign pro 
se small entities would vary depending on the nature of legal services 
provided and complexity of the application.

    \3\ See Am. Intellectual Prop. Law Ass'n, Report of the Economic 
Survey 43 (2023).
    \4\ Copy, drawing, and government fees are not included in the 
rates.
    \5\ The Report on the Economic Survey provides professional 
rates for legal services rendered only in utility applications. 
Because the professional rates in utility applications typically 
represent the upper range of legal costs, these rates will be used 
as a proxy to calculate the costs for legal services rendered for 
all applications, including plant and design applications.
---------------------------------------------------------------------------

    Tables 3, 4, and 5 below provide the estimated costs for a U.S. 
patent practitioner to prosecute an application based on professional 
rates as reported by the American Intellectual Property Law Association 
in the 2023 Report on the Economic Survey.\3\ The professional rates 
\4\ shown below are the median charges in FY 2022 for legal services 
rendered for a utility application.\5\ The tables do not include 
services for which legal counsel is not required (e.g., payment of 
maintenance fees) or services that are not part of prosecution (such as 
ex parte reexamination, novelty search, validity and infringement 
opinions, and reference management). The figures in Tables 3 and 4 show 
the estimated legal cost for prosecuting applications that are of 
minimal complexity as well as applications that are relatively complex.
    Table 3 below provides the estimated cost to impacted entities if a 
U.S. patent practitioner is retained prior to filing of a non-
provisional application. These cases include applications of foreign 
origin where no substantive direction is provided by the foreign 
attorney, and thus the patent practitioner would be required to provide 
substantive legal advice to prosecute the application, including legal 
services connected with preparing, filing, and prosecuting an 
application. Based on the total estimated number of applications filed 
by foreign applicants/inventors and patent owners that are also 
considered to be small entities, the total legal cost for non-
provisional applications to comply with this proposed rule would range 
from $13,124,820 to $13,334,200 for minimal complexity applications, to 
$16,430,820 to $19,395,200 for relatively complex applications.

    Table 4 below provides the estimated cost to impacted entities if a 
U.S. patent practitioner is retained to file a non-provisional 
application of foreign origin that is in condition for filing and in 
which the foreign attorney provides substantive direction. In these 
cases, the U.S. patent practitioner would provide only minimal legal 
services connected with the initial filing an application and the 
subsequent filing of other documents. Based on the total estimated 
number of applications filed by foreign applicants/inventors and patent 
owners that are also considered to be small entities, the total legal 
cost for a non-provisional application to comply with this proposed 
rule would range from $4,336,370 to $4,545,750 for minimal complexity 
applications, to $5,190,420 to $5,399,800 for relatively complex 
applications.

    Table 5 below provides a list of services that may be provided to 
impacted entities before or during prosecution, but are dependent on 
the nature of the application. The prosecution of a patent application 
is highly variable and a particular application may or may not require 
any of these services. If these services are provided, then the costs 
below would be added to the total legal costs in Tables 3 or 4, as 
applicable. The table below provides the percentage of all applications 
that have utilized these services.

    As seen above, the USPTO estimates that only 1,102 (or 1.4%) 
foreign pro se small entities would be impacted by this proposed rule. 
This is a very small number when compared to the 76,213 total foreign 
small entities that file patent applications. Although the number of 
impacted small entities is not expected to be substantial, the economic 
impact varies depending on the nature of legal services provided and 
complexity of the application. Because prosecution of patent 
applications is highly variable, the legal costs incurred by the 1,102 
foreign pro se small entities would depend on whether the application 
is of U.S. origin or foreign origin, with applications of U.S. origin 
incurring more cost than those of foreign origin, and the level of 
complexity of the application, with relatively complex applications 
incurring more cost than minimally complex applications. Legal costs 
would increase if any of the additional available services are utilized 
before or during prosecution.
    Alternative 1: The USPTO also considered the alternative to take no 
action and maintain the status quo (``Alternative 1''). Alternative 1 
was rejected because the USPTO has determined that the requirement that 
foreign applicant/inventors and patent owners to be represented by a 
registered patent practitioner is needed to accomplish the stated 
objectives to increase efficiency and enable the USPTO to more 
effectively use available mechanisms to enforce compliance with U.S. 
statutory and regulatory requirements in patent matters, and to enhance 
the USPTO's ability to respond to false certifications, 
misrepresentations, and fraud.

C. Executive Order 12866 (Regulatory Planning and Review)

    This rulemaking has been determined to be not significant for 
purposes of Executive Order 12866 (September 30, 1993).

D. Executive Order 13563 (Improving Regulation and Regulatory Review)

    The USPTO has complied with Executive Order 13563 (January 18, 
2011). Specifically, and as discussed above, the USPTO has, to the 
extent feasible and applicable: (1) reasonably determined that the 
benefits of the rule justify its costs; (2) tailored the rule to impose 
the least burden on society consistent with obtaining the agency's 
regulatory objectives; (3) selected a regulatory approach that 
maximizes net benefits; (4) specified performance objectives; (5) 
identified and assessed available alternatives; (6) involved the public 
in an open exchange of information and perspectives among experts in 
relevant disciplines, affected stakeholders in the private sector, and 
the public as a whole, and provided online access to the rulemaking 
docket; (7) attempted to promote coordination, simplification, and 
harmonization across government agencies and identified goals designed 
to promote innovation; (8) considered approaches

[[Page 60601]]

that reduce burdens while maintaining flexibility and freedom of choice 
for the public; and (9) ensured the objectivity of scientific and 
technological information and processes.

E. Executive Order 14192 (Deregulation)

    This regulation is not an Executive Order 14192 regulatory action 
because it is not significant under Executive Order 12866.

F. Executive Order 13132 (Federalism)

    This rulemaking pertains strictly to federal agency procedures and 
does not contain policies with federalism implications sufficient to 
warrant preparation of a Federalism Assessment under Executive Order 
13132 (August 4, 1999).

G. Executive Order 13175 (Tribal Consultation)

    This rulemaking will not: (1) have substantial direct effects on 
one or more Indian tribes; (2) impose substantial direct compliance 
costs on Indian tribal governments; or (3) preempt tribal law. 
Therefore, a tribal summary impact statement is not required under 
Executive Order 13175 (November 6, 2000).

H. Executive Order 13211 (Energy Effects)

    This rulemaking is not a significant energy action under Executive 
Order 13211 because this rulemaking is not likely to have a significant 
adverse effect on the supply, distribution, or use of energy. 
Therefore, a Statement of Energy Effects is not required under 
Executive Order 13211 (May 18, 2001).

I. Executive Order 12988 (Civil Justice Reform)

    This rulemaking meets applicable standards to minimize litigation, 
eliminate ambiguity, and reduce burden as set forth in sections 3(a) 
and 3(b)(2) of Executive Order 12988 (February 5, 1996).

J. Executive Order 13045 (Protection of Children)

    This rulemaking does not concern an environmental risk to health or 
safety that may disproportionately affect children under Executive 
Order 13045 (April 21, 1997).

K. Executive Order 12630 (Taking of Private Property)

    This rulemaking will not effect a taking of private property or 
otherwise have taking implications under Executive Order 12630 (March 
15, 1988).

L. Congressional Review Act

    Under the Congressional Review Act provisions of the Small Business 
Regulatory Enforcement Fairness Act of 1996 (5 U.S.C. 801, et seq.), 
the USPTO will submit a report containing the final rule and other 
required information to the United States Senate, the United States 
House of Representatives, and the Comptroller General of the Government 
Accountability Office. The changes in this rulemaking are not expected 
to result in an annual effect on the economy of $100 million or more, a 
major increase in costs or prices, or significant adverse effects on 
competition, employment, investment, productivity, innovation, or the 
ability of United States-based enterprises to compete with foreign-
based enterprises in domestic and export markets. Therefore, this 
rulemaking is not expected to result in a ``major rule'' as defined in 
5 U.S.C. 804(2).

M. Unfunded Mandates Reform Act of 1995

    The changes set forth in this rulemaking do not involve a Federal 
intergovernmental mandate that will result in the expenditure by State, 
local, and tribal governments, in the aggregate, of $100 million (as 
adjusted) or more in any one year, or a Federal private sector mandate 
that will result in the expenditure by the private sector of $100 
million (as adjusted) or more in any one year, and will not 
significantly or uniquely affect small governments. Therefore, no 
actions are necessary under the provisions of the Unfunded Mandates 
Reform Act of 1995. See 2 U.S.C. 1501 et seq.

N. National Environmental Policy Act of 1969

    This rulemaking will not have any effect on the quality of the 
environment and is thus categorically excluded from review under the 
National Environmental Policy Act of 1969. See 42 U.S.C. 4321 et seq.

O. National Technology Transfer and Advancement Act of 1995

    The requirements of section 12(d) of the National Technology 
Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) are not 
applicable because this rulemaking does not contain provisions that 
involve the use of technical standards.

P. Paperwork Reduction Act of 1995

    The Paperwork Reduction Act of 1995 (44 U.S.C. 3501, et seq.) 
requires that the USPTO consider the impact of paperwork and other 
information collection burdens imposed on the public. The collection of 
information involved in this proposed rule has been reviewed and 
previously approved by OMB under control number 0651-0035. The USPTO 
will submit an update to the 0651-0035 information collection in the 
form of a nonsubstantive change request.
    Notwithstanding any other provision of law, no person is required 
to respond to, nor shall any person be subject to a penalty for failure 
to comply with, a collection of information subject to the requirements 
of the Paperwork Reduction Act unless that collection of information 
displays a currently valid OMB control number.

Q. E-Government Act Compliance

    The USPTO is committed to compliance with the E-Government Act to 
promote the use of the internet and other information technologies, to 
provide increased opportunities for citizen access to Government 
information and services, and for other purposes.
