[Docket No. PTO-P-2025-0545]
RIN 0651-AD94


Requirement To Identify All Real Parties in Interest to a Third 
Party Request for an Ex Parte Reexamination

AGENCY: United States Patent and Trademark Office, Department of 
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 to require a third 
party request for ex parte reexamination to include a statement by the 
third party requester identifying all real parties in interest to the 
ex parte reexamination request. This statement would be kept 
confidential upon request. This proposed requirement would provide the 
Office with a mechanism to evaluate statutory estoppel provisions. It 
would also enhance the Office's ability to respond to false 
certifications, misrepresentations, and fraud.

DATES: Comments must be received by August 21, 2026 to ensure 
consideration.

ADDRESSES: For reasons of Government efficiency, comments must be 
submitted through the Federal eRulemaking Portal at: https://www.regulations.gov. To submit comments via the portal, one should

Commissioner for Patents.

SUPPLEMENTARY INFORMATION:

I. Introduction

    Currently, a third party requester may submit an ex parte 
reexamination request anonymously without identifying the real 
party(ies) in interest to the request (i.e., the identity of the 
requester and any other real parties in interest). See 37 CFR 1.501(d) 
and Manual of Patent Examining Procedure (MPEP) (9th ed., Rev. 01.2024,

[[Page 46039]]

November 2024) section 2214, subsection I. 35 U.S.C. 302 states ``[a]ny 
person at any time may file a request for reexamination by the Office 
of any claim of a patent on the basis of any prior art cited under the 
provisions of section 301.'' Under 35 U.S.C. 301(e), a person citing to 
the Office prior art or written statements may request that the 
``person's identity [ ] be excluded from the patent file and kept 
confidential.'' When enacting Section 301(e), Congress explained that, 
``[w]ithout the confidentiality provision, competitors of a patent 
owner might be reluctant to cite prior art to the [Office].'' H.R. Rep. 
96-1307, 6, 1980 U.S.C.C.A.N. 6460, 6465. 37 CFR 1.501(d) further 
states ``[i]f the person making the submission wishes his or her 
identity to be excluded from the patent file and kept confidential, the 
submission papers must be submitted anonymously without any 
identification of the person making the submission.''
    Therefore, under the Office's current rules and procedures, the 
identity of the party(ies) seeking the reexamination may be concealed 
from both the public and the Office. While the Office recognizes the 
importance and continuing applicability of Section 301(e), that 
provision only requires keeping the requester's identity confidential 
from the public, not from the Office. Similarly, current 35 U.S.C. 
315(e), which was enacted years after Sections 301 and 302, requires 
the Office to administer estoppels triggered by the identity of the 
party(ies) seeking reexamination. The Office is proposing to amend the 
rules of practice to require a third party request for ex parte 
reexamination to include a statement by the third party requester 
identifying all real parties in interest to the ex parte reexamination 
request. Upon request, that statement would be excluded from the patent 
and reexamination files and kept confidential.

II. Background

A. 2012 AIA Rulemaking

    The Leahy-Smith America Invents Act (Pub. L. 112-29, 125 Stat. 284 
(2011)), effective in 2012, contains statutory estoppel provisions in 
35 U.S.C. 315(e)(1) and 35 U.S.C. 325(e)(1) regarding proceedings 
before the Office. Specifically, these estoppel provisions prevent a 
petitioner in an inter partes review or post-grant review of a claim in 
a patent that results in a final written decision under 35 U.S.C. 
318(a) or 328(a), or the real party in interest or privy of the 
petitioner, from requesting or maintaining a proceeding before the 
Office with respect to that claim on any ground that the petitioner 
raised or reasonably could have raised during that inter partes review 
or post-grant review. When enacting the Leahy-Smith America Invents 
Act, a member of Congress stated ``[t]he Office recognizes that it will 
need to change its regulations and require that ex parte reexamination 
requesters identify themselves to the Office in order for the Office to 
be able to enforce this new [estoppel] restriction.'' 157 Cong. Rec. 
S1376 (Mar. 8, 2011) (Sen. Kyl).
    In January 2012, the Office issued a Notice of Proposed Rulemaking 
that proposed new 37 CFR 1.510(b)(6) and (b)(7). See Changes to 
Implement Miscellaneous Post Patent Provisions of the Leahy-Smith 
America Invents Act, 77 FR 442 (Jan. 5, 2012) (``January 2012 Notice of 
Proposed Rulemaking''). Proposed Sec.  1.510(b)(6) introduced a 
certification requirement that was adopted with some modification in a 
final rule. See Changes to Implement Miscellaneous Post Patent 
Provisions of the Leahy-Smith America Invents Act, 77 FR 46615 (Aug. 6, 
2012) (``August 2012 Final Rule''). As adopted, Sec.  1.510(b)(6) 
requires that a third party request for ex parte reexamination contain 
a certification by the third party requester that the statutory 
estoppel provisions of inter partes review and post-grant review at 35 
U.S.C. 315(e)(1) or 35 U.S.C. 325(e)(1), respectively, do not bar the 
third party from requesting ex parte reexamination.
    Proposed 37 CFR 1.510(b)(7) required identification of the real 
party(ies) in interest to a request for ex parte reexamination, but it 
was not adopted by the Office. See August 2012 Final Rule, 77 FR at 
46621-22. At that time, the Office considered the certification 
requirement of Sec.  1.510(b)(6), coupled with a party's obligations 
under 37 CFR 11.18 when transacting business before the Office, 
sufficient to ensure compliance with the statutory estoppel 
requirements. Id. Several comments in response to the 2012 proposed 
rule suggested that requiring identification of the real party(ies) in 
interest could have a chilling effect on the submission of ex parte 
reexamination requests. See Comment 20, August 2012 Final Rule, 77 FR 
at 46621. Several other comments pointed out that, should the Office 
retain the requirement for identification of the real party(ies) in 
interest, procedures for safeguarding anonymity are critical. See 
Comment 25, August 2012 Final Rule, 77 FR at 46622. Further, a number 
of comments suggested that the statement identifying the real 
party(ies) in interest be deleted because it is unnecessary in view of 
the certification in Sec.  1.510(b)(6). Id.
    Thus, as adopted, the 2012 rules allowed the identity of real 
party(ies) in interest to a request for ex parte reexamination to 
remain concealed from both the Office and the public.

B. Anonymous Requests for Ex Parte Reexamination

    Currently, a real party in interest that wishes to remain anonymous 
when filing a request for reexamination under Sec.  1.510 can do so by 
utilizing the services of a registered practitioner. See MPEP 2214, 
subsection I. In such an instance, the registered practitioner 
submitting a request for reexamination on behalf of the real party in 
interest to the request would be certifying, pursuant to Sec.  
1.510(b)(6), that the real party in interest was not estopped under 35 
U.S.C. 315(e)(1) or 325(e)(1) from filing the request.
    Under 37 CFR 11.18(b), a party presenting a paper to the Office 
must certify, among other things, that: (1) all statements made therein 
are true or believed to be true, and that knowingly and willfully 
making any false or fraudulent statement is subject to criminal 
penalties; and (2) to the best of the party's knowledge, information 
and belief, formed after an inquiry reasonable under the circumstances, 
the paper is not being presented for any improper purpose, such as to 
harass someone or to cause unnecessary delay or needless increase in 
the cost of any proceeding before the Office, and the legal contentions 
therein are warranted by existing law or by a nonfrivolous argument for 
the extension, modification, or reversal of existing law or the 
establishment of new law. As previously discussed, the certification 
requirement under Sec.  1.510(b)(6), coupled with the party's Sec.  
11.18 certification obligations, had been considered sufficient to 
ensure compliance with the inter partes review and post-grant review 
statutory estoppel requirements.
    However, this ability to file an anonymous request for ex parte 
reexamination is in tension with the estoppel provisions of 35 U.S.C. 
315(e)(1) and 325(e)(1). The Office cannot independently ascertain 
whether the party is estopped if the identity of the requester, and all 
real parties in interest to the request, are not identified.

III. Requirement To Identify All Real Parties in Interest to a Third 
Party Request for Ex Parte Reexamination

    The Office is currently receiving a significant number of ex parte 
reexamination requests under 35 U.S.C. 302 that are directed to patents

[[Page 46040]]

previously challenged in inter partes or post-grant review proceedings. 
Thus, there is risk that the statutory estoppel provisions of 35 U.S.C. 
315(e)(1) or 35 U.S.C. 325(e)(1) may apply to the real party(ies) in 
interest to an ex parte reexamination request. Additionally, because 
the issue of whether a party is a real party in interest can be a 
disputed question, there is a possibility that the Office's reliance on 
a party's 37 CFR 1.510(b)(6) certification alone, even if provided in 
good faith, could result in ordering reexamination on a request that 
otherwise should be barred by the statutory estoppel provisions of 35 
U.S.C. 315(e)(1) or 35 U.S.C. 325(e)(1). Under the current 
certification practice, the Office does not know the identity of the 
real party(ies) in interest to an anonymous request. That can lead to 
inefficient use of Office resources when considering whether estoppel 
applies, including when considering petitions by patent owners 
disputing a third party requester's Sec.  1.510(b)(6) certification. 
Requiring disclosure to the Office of all real parties in interest to 
the request will promote complete and efficient evaluation of whether 
estoppel applies, thereby protecting patent owners from requests that 
are subject to estoppel. Ultimately, proceeding with a reexamination 
request where one or more parties should be estopped would not only be 
statutorily improper, but would waste Office resources in conducting an 
improper reexamination proceeding, and would be unfair to the patent 
owner to have to defend against a reexamination proceeding that should 
have been barred by statute.
    In view of these shortcomings, the Sec.  1.510(b)(6) certification 
and the obligations of Sec.  11.18(b) are no longer deemed sufficient 
to ensure compliance with the statutory estoppel provisions. The Office 
has determined that it needs the identity of all real party(ies) in 
interest to the reexamination request in order to effectively and 
efficiently evaluate 35 U.S.C. 315(e)(1) or 35 U.S.C. 325(e)(1) 
estoppel.
    The Office is proposing to amend the rules of practice to add Sec.  
1.510(b)(7), requiring a request for ex parte reexamination to include 
a statement by a third party requester identifying all real parties in 
interest to the ex parte reexamination request, which statement would 
be retained in confidence upon request. Specifically, the Office is 
requiring identification of the requester and any other real parties in 
interest to the request. The Office recognizes the public's concerns 
about ensuring confidentiality of the requester's identity that are 
reflected in the comments to the January 2012 Notice of Proposed 
Rulemaking and will take appropriate steps to alleviate those concerns. 
When a third party requester files the proposed Sec.  1.510(b)(7) 
statement according to parameters established by the Office and 
requests the statement remain confidential, the Office intends to 
provide robust data security measures to exclude the statement from the 
patent and reexamination files and keep the statement confidential. 
These measures would assist in providing the critical safeguarding of 
the confidential information desired by stakeholders and required by 35 
U.S.C. 301(e) and 302, thereby reducing any chilling effect on the 
submission of ex parte reexamination requests. Furthermore, the Office 
recognizes that it may need to rely on the confidential real party(ies) 
in interest information in making determinations and decisions during 
the course of the reexamination proceeding. The Office will take 
reasonable steps to ensure that any decision will not disclose the 
confidential information.
    The proposed Sec.  1.510(b)(7) statement requiring identification 
of all real parties in interest to the ex parte reexamination request 
is expected to provide more efficient and effective evaluation of the 
estoppel provisions while still maintaining the confidentiality of a 
requester's identity as required by 35 U.S.C. 301(e) and 302. Also, the 
proposed Sec.  1.510(b)(7) statement would better serve Congress's 
intent in enacting the Section 315(e)(1) and 325(e)(1) estoppel 
provisions to ``significantly reduce the ability to use post-grant 
procedures for abusive serial challenges to patents.'' 157 Cong. Rec. 
S936, S952 (daily ed. Feb. 28, 2011) (statement of Sen. Grassley). 
Further, the identification requirement in proposed Sec.  1.510(b)(7) 
is consistent with the existing inter partes review and post-grant 
review practice of identifying all real parties in interest. See, e.g., 
35 U.S.C. 312(a)(2) (requiring a petition for inter partes review to 
identify all real parties in interest).
    The proposed Sec.  1.510(b)(7) statement would also be beneficial 
should the Office implement the recently proposed changes to 37 CFR 
42.108 (``Institution of inter partes review'') regarding the rules of 
practice before the Patent Trial and Appeal Board (PTAB). See Revision 
to Rules of Practice Before the Patent Trial and Appeal Board, 90 FR 
48335 (Oct. 17, 2025) (``PTAB Notice of Proposed Rulemaking''). 
Proposed Sec.  42.108(e)(5) would preclude inter partes review of a 
claim if it was found patentable following a prior ex parte 
reexamination request filed by someone other than the patent owner or 
the patent owner's real party in interest or privy. PTAB Notice of 
Proposed Rulemaking, 90 FR at 48341. A comment in response to proposed 
Sec.  42.108(e)(5) raised concerns that a requester's ability to file 
an ex parte reexamination request anonymously would undercut this 
provision. See Comment PTO-P-2025-0025-2022, page 8 (available at 
www.regulations.gov/docket/PTO-P-2025-0025). This proposed Sec.  
1.510(b)(7) statement would ensure that the Office is aware of the 
identity of all real parties in interest to the ex parte reexamination 
request when determining whether to allow an inter partes review to 
proceed.
    The benefits of the proposed Sec.  1.510(b)(7) identification 
requirement also extend to situations where there are no prior inter 
partes review or post-grant review proceedings involving the same 
patent. Gathering information regarding the real parties in interest to 
a third party request for ex parte reexamination would facilitate fraud 
mitigation. For example, the USPTO currently issues show cause orders 
in reexamination proceedings where an apparent misrepresentation has 
been made, such as unauthorized practice before the USPTO. Having the 
real party(ies) in interest information available upon filing of a 
request could eliminate ambiguities in such instances or permit the 
USPTO to act more efficiently when it is clear a misrepresentation was 
made in the request, thereby protecting the integrity of the U.S. 
patent system.

IV. Discussion of Specific Sections

    The USPTO proposes to amend 37 CFR part 1 as follows:

Section 1.501(d)

    Proposed Sec.  1.501(d) would be revised to clarify that papers 
submitted ``under this section'' (i.e., mere citations of prior art and 
written statements) can be submitted anonymously without any 
identification of the person making the submission. The language 
``under this section'' would be added to distinguish citations of prior 
art and written statements submitted under Sec.  1.501, which may still 
be submitted anonymously, from ex parte reexamination requests under 
Sec.  1.510, which would now require identification of all real parties 
in interest to the request.

Section 1.510(b)

    Proposed Sec.  1.510(b)(7) would require a third party requester to 
submit a statement identifying all real parties in interest to the ex 
parte reexamination request (i.e., the requester and any other

[[Page 46041]]

real parties in interest). The statement would be required to be 
submitted electronically according to the parameters established by the 
Office and published on the website of the Office. To be consistent 
with 35 U.S.C. 301(e) and 302, proposed 37 CFR 1.510(b)(7) would 
further permit the statement identifying all real parties in interest 
to be excluded from the patent and reexamination files and kept 
confidential upon request. The requirements of proposed Sec.  
1.510(b)(7) would apply only to a third party request for 
reexamination, and would not apply to a reexamination request submitted 
by a party that identifies itself in the request as the patent owner. 
Although, Sec.  1.11(d) requires all papers relating to a reexamination 
proceeding which have been entered of record in the patent or 
reexamination file to be open to inspection by the general public, the 
statement under proposed Sec.  1.510(b)(7) would not be entered of 
record in the patent or reexamination file if a requester asks that it 
be kept confidential. Accordingly, confidential information submitted 
under proposed Sec.  1.510(b)(7) would not be made available to the 
public under Sec.  1.11(d).
    Determining whether a party is a real party in interest to the 
request is a highly fact-dependent question that is determined on a 
case-by-case basis. See Applications in Internet Time, LLC v. RPC 
Corp., 897 F.3d 1336 (Fed. Cir. 2018); see generally Taylor v. 
Sturgell, 553 U.S. 880 (2008). For guidance in making this 
determination under Sec.  1.510(b)(6) and proposed Sec.  1.510(b)(7), 
parties may consult prevailing Federal Circuit precedent, precedential 
and informative Board decisions, and Office guidance, including the 
Office's Consolidated Trial Practice Guide concerning the determination 
of real parties in interest in PTAB proceedings. See Trial Practice 
Guide, October 2025, section I(D)(1), https://www.uspto.gov/patents/ptab/trial-practice-guide.

V. Rulemaking Considerations

    A. Administrative Procedure Act: This rulemaking would revise the 
procedures governing the filing of a request for ex parte reexamination 
with the Office to require a third party request for ex parte 
reexamination to include a statement by the third party requester 
identifying all real parties in interest to the ex parte reexamination 
request. 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''); 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: For the reasons set forth herein, 
the Senior Counsel for Regulatory and Legislative Affairs, Office of 
General Law, of the USPTO has certified to the Chief Counsel for 
Advocacy of the Small Business Administration that changes in this rule 
will not have a significant economic impact on a substantial number of 
small entities. See 5 U.S.C. 605(b). This proposed rule would revise 37 
CFR 1.510(b) to add a new provision requiring any third party request 
for ex parte reexamination to include a statement by a third party 
requester identifying all real parties in interest to the ex parte 
reexamination request. Third party requesters can be any person other 
than the owner of the patent being challenged. In fiscal year 2025, the 
USPTO received 452 requests for ex parte reexamination. In 174 (38%) of 
those 452 requests, the requesters paid the small entity fee. The USPTO 
will consider those 174 requesters who paid the small entity fee to be 
small entities for the purposes of this analysis. Ex parte 
reexamination requests could involve any patent issued in any 
technology area, thus the proposed new requirement may impact any 
industry. Although a substantial number of small entities may be 
impacted by the new requirement that third party requesters supply the 
identity of the real parties in interest, the proposed new requirement 
would result in only a de minimis additional burden on third party 
requesters over the current certification practice. This proposed rule 
does not impose any additional fees on impacted entities. Thus, for the 
foregoing reasons, the changes in this proposed rule will not have a 
significant economic impact on a substantial number of small entities.
    C. Executive Order 12866 (Regulatory Planning and Review): This 
rulemaking has been determined to be significant under section 3(f) 
Executive Order 12866 (Sept. 30, 1993).
    D. Executive Order 13563 (Improving Regulation and Regulatory 
Review): The USPTO has complied with Executive Order 13563 (Jan. 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 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 results in de 
minimis costs on respondents.
    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 (Aug. 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

[[Page 46042]]

Indian tribal governments; or (3) preempt tribal law. Therefore, a 
tribal summary impact statement is not required under Executive Order 
13175 (Nov. 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 (Feb. 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 (Apr. 
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 (Mar. 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: 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: 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 which 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.) (PRA) requires that the USPTO consider 
the impact of paperwork and other information collection burdens 
imposed on the public. The rules of practice pertaining to requests for 
ex parte reexamination have been reviewed and approved by the OMB under 
the PRA under OMB control number 0651-0064 (Patent Reexaminations, 
Supplemental Examinations, and Post Patent Submissions). This OMB 
control number will be updated if necessary to reflect this action.
    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 PRA 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.
