Protest Before Allowance Notice
Note:
A protest can be filed during a reissue application before the allowance notice is mailed, subject to examination timing constraints.

A protest pursuant to 37 CFR 1.291 may be filed throughout the pendency of a reissue application, before the date of mailing of a notice of allowance, subject to the timing constraints of the examination, as set forth in MPEP § 1901.04. While a reissue application is not published under 37 CFR 1.211, the reissue application is published pursuant to 35 U.S.C. 122(b)(1)(A) via an announcement in the Official Gazette (and public availability of the file contents) per 37 CFR 1.11(b). Such a publication does not preclude the filing of a protest. 35 U.S.C. 122(c) states:

Protest Not Permitted After Publication for Original Patents But Allowed in Reissues
Note:
A protest cannot be filed after publication for an original patent application but is allowed after publication in a reissue application.

A protest is precluded after publication for an application for an original patent, as a "form of pre-issuance opposition." A reissue application is a post-issuance proceeding. A protest filed in a reissue application is not a "form of pre-issuance opposition to the grant of a patent" because the patent to be reissued has already been granted. Thus, the prohibition against the filing of a protest after publication of an application under 35 U.S.C. 122(c) is not applicable to a reissue application and a protest is permitted after publication of the reissue application.

Note:
A protest must be filed before an allowance notice is given or mailed; otherwise, it will not be considered.

A protest with regard to a reissue application should be filed within the 2-month period following the announcement of the filing of the reissue application in the Official Gazette. A potential protestor should be aware that reissue applications are taken up “special” and a protest filed outside the 2-month delay period may be received after action by the examiner. Further, if a protest is filed after a final rejection has been issued or prosecution on the merits has been otherwise closed for the reissue application, a petition for entry of the protest under 37 CFR 1.182 is required. The petition must include an explanation as to why the additional time was necessary and the nature of the protest intended.

Petition to Waive Reissue Delay Period
Note:
Reissue applicants can petition to waive the 2-month delay period under appropriate circumstances, but protestors should file early if they wish their protest considered promptly.

If the protest is a "REISSUE LITIGATION" protest, it is particularly important that it be filed early if protestor wishes it considered at the time the Office first acts on the reissue application. Protestors should be aware that the Office will entertain petitions from the reissue applicants under 37 CFR 1.182 to waive the 2-month delay period in appropriate circumstances.
