During a reexamination proceeding, if a patent owner fails to file a timely response or appeal, and the examiner verifies that no such response was filed, what procedure should the examiner follow?
According to the MPEP text, a panel review conference is not to be held because the proceeding is to be concluded by the cancellation of all claims. Instead, the examiner will issue a NIRC action and draft an attached examiner's amendment canceling all live claims in the reexamination proceeding.

In a reexamination proceeding where all live claims are under rejection and the patent owner fails to timely respond to an Office action, all claims are to be canceled. Prior to canceling the claims and issuing a Notice of Intent to Issue Reexamination Certificate (NIRC), what action should the examiner take?
According to the MPEP guidelines regarding reexamination proceedings in which all claims are to be canceled, prior to canceling the claims and issuing the NIRC, the examiner should telephone the patent owner to inquire if a timely response, timely appeal, etc., was filed with the Office to make certain that no response/appeal was filed.

According to the MPEP, when extensive amendments are necessary in a reexamination proceeding, why is it preferable for the amendments to be filed by the patent owner's attorney or agent of record rather than being executed as an examiner's amendment?
As stated in the MPEP text, when extensive amendments are necessary, it is preferable for the amendments to be filed by the patent owner's attorney or agent of record since this provides the file wrapper with a better record because the amendments would include the patent owner's arguments for patentability as required by 37 CFR 1.111.

How MPEP 2200 Ex Parte Reexam Is Tested on the 2026 Patent Bar Exam
MPEP Chapter 2200 (Citation of Prior Art and Ex Parte Reexamination of Patents) is a high-precision topic on the Patent Bar. Every question hinges on the strict statutory scope of ex parte reexamination under 35 U.S.C. 301–302: reexamination can ONLY be ordered based on prior art consisting of patents or printed publications (plus patent owner claim scope statements under 35 U.S.C. 301(a)(2)). Issues like public use, on-sale bar, 35 U.S.C. 101 eligibility, or 35 U.S.C. 112 compliance of original patent claims cannot be raised in ex parte reexamination.
However, once reexamination is ordered based on a Substantial New Question of Patentability (SNQ, which the USPTO must determine within 3 months of the filing date of the request), ANY amended or newly added claims ARE examined for compliance with 35 U.S.C. 112 (though still not 101). Furthermore, under 35 U.S.C. 305, no proposed amended or new claim may enlarge the scope of the claims of the patent.
Also watch the Patent Owner’s Statement trap (MPEP § 2249): after reexamination is ordered, the patent owner has 2 months to file a statement; third-party requesters may ONLY file a reply (within 2 months) if the patent owner actually files a statement. Thus, patent owners almost never file a statement in practice.

Frequently Asked Questions: MPEP 2200 Ex Parte Reexam
Can a third-party requester file an ex parte reexamination request anonymously?
Yes. Under 35 U.S.C. 302 and MPEP § 2212, any person may file a request for ex parte reexamination at any time during the period of enforceability of a patent, and an attorney may file the request on behalf of an anonymous real party in interest (as long as the requester is not estopped under AIA post-grant provisions).
Are original patent claims examined under 35 U.S.C. 112 or 35 U.S.C. 101 during ex parte reexamination?
No. Under MPEP § 2258, original patent claims are examined ONLY on the basis of patents and printed publications under 35 U.S.C. 102 and 103. Only new or amended claims presented during reexamination are examined for compliance with 35 U.S.C. 112.
Can a patent owner file a continuation or RCE in an ex parte reexamination proceeding?
No. Under 37 CFR 1.114(e) and MPEP § 2252, neither an RCE nor a continuing application under 35 U.S.C. 120 may be filed in an ex parte reexamination proceeding.
