Reply brief
- Under 37 CFR 41.41(a)(1), a single reply brief may be filed as a matter of right within the later of two months from the date of either the examiner’s answer, or a decision refusing to grant a petition under 37 CFR 1.181 to designate a new ground of rejection in an examiner’s answer.
- Extensions of time to file the reply brief may be granted pursuant to 37 CFR 1.136(b) (for patent applications) or 1.550(c) (for ex parte reexamination proceedings). Extensions of time under 37 CFR 1.136(a) are not permitted.

Appeal forwarding fee
Oral hearing (if requested)
Decision by Board
Affirmed
- After decision by the Board, jurisdiction over an application or patent under ex parte reexamination proceeding passes to the examiner, subject to appellant's right of appeal or other review, for such further action by appellant or by the examiner, as the condition of the application or patent under ex parte reexamination proceeding may require, to carry into effect the decision. 37 CFR 41.54
- Proceedings on the application are considered terminated by the failure to timely file an appeal to the court or a civil action except: (1) where claims stand allowed in the application; or (2) where the nature of the decision requires further action by the examiner. 37 CFR 1.197(a).
- To continue prosecution of the application, an amendment can be filed after the Board’s decision which presents a new or amended claim or claims along with a request for continued examination (RCE) under 37 CFR 1.114 and the fee set forth in 37 CFR 1.17(e). See MPEP § 706.07(h), subsection XI.
Affirmed-in-part
- The decision reverses all of the examiner’s rejections pertaining to at least one, but not all, of the claims.
Reversed
- A complete reversal of the examiner’s rejection(s) brings the case up for immediate action by the examiner. The examiner should not regard a reversal as an opportunity to make a new search to uncover other and better references. See MPEP 1214.04. However, if the examiner has specific knowledge of a particular reference or references which indicate nonpatentability of any of the appealed claims, the examiner should submit the matter to the Technology Center (TC) Director or Central Reexamination Unit (CRU) for authorization to reopen prosecution under 37 CFR 1.198 for the purpose of entering the new rejection.

When to file a request for rehearing
- An appellant may file a request for rehearing within two (2) months of the date of the original decision of the Board. 37 CFR 41.52(a)(1).

Arguments not raised, and Evidence not previously relied upon are not permitted in the request for rehearing except as permitted by 37 CFR 41.52(a)(2)-(a)(4). 37 CFR 41.52(a)(1).
Decision on a request for rehearing
- No request for rehearing from a decision on rehearing is permitted unless the rehearing decision so modified the original decision as to become, in effect, a new decision AND the Board states that a second request for rehearing would be permitted. 37 CFR 41.52(a)(1).
