Amendment After Non-Compliant Brief
Note:
An amendment filed after a non-compliant appeal brief is considered under 37 CFR 41.33(b), not 41.33(a).

The submission of an amendment after the filing of a non-compliant brief will be considered under 37 CFR 41.33(b). For example, applicant files a notice of appeal and an appeal brief on July 14, 2022. Applicants files an amendment under 37 CFR 41.33(b) on August 19, 2022. In response to a notice of defective appeal brief, applicant timely files an amended brief on September 19, 2022. The filing of the amendment on August 19, 2022, will be considered under 37 CFR 41.33(b) and not under 41.33(a). If prosecution is reopened, then the filing of the non-complaint appeal brief on July 14, 2022, would not be used to determine whether the amendment was filed after the filing of the appeal brief.

Timing of Amendments After Non-Compliant Briefs
Note:
If prosecution is reopened, the filing date of a non-compliant appeal brief does not determine whether an amendment was filed after the initial appeal brief.

The submission of an amendment after the filing of a non-compliant brief will be considered under 37 CFR 41.33(b). For example, applicant files a notice of appeal and an appeal brief on July 14, 2022. Applicants files an amendment under 37 CFR 41.33(b) on August 19, 2022. In response to a notice of defective appeal brief, applicant timely files an amended brief on September 19, 2022. The filing of the amendment on August 19, 2022, will be considered under 37 CFR 41.33(b) and not under 41.33(a). If prosecution is reopened, then the filing of the non-complaint appeal brief on July 14, 2022, would not be used to determine whether the amendment was filed after the filing of the appeal brief.

Separate Non-Admitted Amendments from Appeal Briefs
Note:
Appellants must submit non-admitted amendments separately from their appeal briefs.

37 CFR 41.37(c)(2) provides that a brief shall not include any non-admitted amendment. Thus, appellants may not include an amendment under 37 CFR 41.33(b) in the appeal brief. Should appellants wish to file an amendment at the same time as a brief, appellants must submit such an amendment in a paper separate from the appeal brief.

Board Does Not Consider Late Amendments
Note:
The Board will not consider amendments filed after appeal jurisdiction transfer until the time period in 37 CFR 90.3 expires, unless remanded for amendment consideration.

Amendments filed after jurisdiction of the appeal is transferred to the Board are not considered prior to the expiration of the time period set forth in 37 CFR 90.3 unless the case is remanded by the Board for consideration of the amendment. If an amendment is considered non-compliant the applicant may not be granted additional time to submit a substitute amendment. As such, it is recommended that appellant rewrite dependent claims, which have been objected to as being allowable except for their dependency on a rejected independent claim, before the appeal is forwarded to the Board. Such amendments must be filed before the expiration of the time period set forth in 37 CFR 90.3, to avoid cancellation of the objected to claims. This includes dependent claims in which the rejections are withdrawn by the examiner in the Examiner’s Answer. See MPEP §§ 1214.06 and 1214.07.

Examiner Must Explain Amendment's Effect on Rejections
Note:
After an appeal, if an examiner indicates that an amendment will be entered, they must explain how the rejection(s) in the final Office action are affected by this amendment, except for cancellations or rewrites of dependent claims.

Examiners must respond to all amendments filed after an appeal has been taken and prior to transfer of jurisdiction to the Board under 37 CFR 41.35(a). If the examiner indicates (in the advisory action) that an amendment would be entered, it is imperative for the examiner to also state (in the same advisory action) how the individual rejection(s) set forth in the final Office action will be impacted by the entry of the amendment except where an amendment merely cancels claims or rewrites dependent claims in independent form. If the examiner determines that an amendment clearly places the application in condition for allowance, the examiner may enter the amendment and allow the application. Except for amendments that meet the conditions set forth above, all other amendments submitted after the date of filing a notice of appeal will not be entered except as permitted by 37 CFR 41.39(b)(1), 41.50(a)(2)(i) and 41.50(b)(1).
