(a) Timing. Any request to seek review of the primary examiner’s failure to designate a rejection as a new ground of rejection in an examiner’s answer must be by way of a petition to the Director under § 1.181 of this title filed within two months from the entry of the examiner’s answer and before the filing of any reply brief. Failure of appellant to timely file such a petition will constitute a waiver of any arguments that a rejection must be designated as a new ground of rejection.

(a) Timing. Any request to seek review of the primary examiner’s failure to designate a rejection as a new ground of rejection in an examiner’s answer must be by way of a petition to the Director under § 1.181 of this title filed within two months from the entry of the examiner’s answer and before the filing of any reply brief. Failure of appellant to timely file such a petition will constitute a waiver of any arguments that a rejection must be designated as a new ground of rejection.

(d) Withdrawal of petition and appeal maintained. If a reply brief under § 41.41 is filed within two months from the date of the examiner’s answer and on or after the filing of a petition under § 1.181 to designate a new ground of rejection in an examiner’s answer, but before a decision on the petition, the reply brief will be treated as a request to withdraw the petition and to maintain the appeal.

(a) Timing. Appellant may file only a single reply brief to an examiner's answer within the later of two months from the date of either the examiner's answer, or a decision refusing to grant a petition under § 1.181 of this title to designate a new ground of rejection in an examiner's answer.

If appellant requests that the appeal be maintained in response to a new ground of rejection made in an examiner’s answer or a substitute examiner’s answer, the appellant must file a reply brief to address each new ground of rejection set forth in the answer in compliance with 37 CFR 41.37(c)(1)(iv) within two months from the mailing of the answer. The reply brief should include the following items, with each item starting on a separate page, so as to follow the other requirements of a brief as set forth in 37 CFR 41.37(c):

• (A) Identification page setting forth the appellant’s name(s), the application number, the filing date of the application, the title of the invention, the name of the examiner, the art unit of the examiner and the title of the paper (i.e., Reply Brief);
• (B) Argument page(s).

If a reply brief is filed in response to a substitute examiner’s answer under 37 CFR 41.50(a) that was written in response to a remand by the Board for further consideration of a rejection, any reply brief accompanied by an amendment, affidavit or other evidence will be treated as a request that prosecution be reopened before the examiner. If appellant fails to file a reply brief or a reply under 37 CFR 1.111 within two months from the mailing of the examiner’s answer that contains a new ground of rejection, or a substitute examiner’s answer under 37 CFR 41.50(a), the appeal may be dismissed. See MPEP § 1207.03 and § 1207.05.

(b) Petition granted and prosecution reopened. A decision granting a petition under § 1.181 to designate a new ground of rejection in an examiner’s answer will provide a two-month time period in which appellant must file a reply under § 1.111 of this title to reopen the prosecution before the primary examiner. On failure to timely file a reply under § 1.111, the appeal will stand dismissed.

(c) Petition not granted and appeal maintained. A decision refusing to grant a petition under § 1.181 of this title to designate a new ground of rejection in an examiner’s answer will provide a two-month time period in which appellant may file only a single reply brief under § 41.41.

(a) Timing. Appellant may file only a single reply brief to an examiner's answer within the later of two months from the date of either the examiner's answer, or a decision refusing to grant a petition under § 1.181 of this title to designate a new ground of rejection in an examiner's answer.

(b) Content.

• (1) A reply brief shall not include any new or non-admitted amendment, or any new or non-admitted affidavit or other Evidence. See § 37 CFR 1.116 of this title for amendments, affidavits or other evidence filed after final action but before or on the same date of filing an appeal and § 41.33 for amendments, affidavits or other Evidence filed after the date of filing the appeal.
• (2) Any argument raised in the reply brief which was not raised in the appeal brief, or is not responsive to an argument raised in the examiner's answer, including any designated new ground of rejection, will not be considered by the Board for purposes of the present appeal, unless good cause is shown.

After receipt of a reply brief under 37 CFR 41.41, jurisdiction over the appeal passes to the Board. Normally, the examiner does not need to acknowledge the reply brief and will not have an opportunity for further argument prior to a decision by the Board. However, the Board may remand the appeal to the examiner to furnish a substitute examiner’s answer responsive to the remand.

(b) Petition granted and prosecution reopened. A decision granting a petition under § 1.181 to designate a new ground of rejection in an examiner’s answer will provide a two-month time period in which appellant must file a reply under § 1.111 of this title to reopen the prosecution before the primary examiner.

(2) Any argument raised in the reply brief which was not raised in the appeal brief, or is not responsive to an argument raised in the examiner's answer, including any designated new ground of rejection, will not be considered by the Board for purposes of the present appeal, unless good cause is shown.

Under 37 CFR 41.41(a)(1), appellant may file a single reply brief 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. Normally, appellant is not required to file a reply brief to respond to an examiner’s answer, and if appellant does not file a reply brief within the two month period of time, the application will be forwarded to the Board for decision on the appeal. In response to the following, however, appellant is required to file either a reply brief to maintain the appeal or a reply under 37 CFR 1.111 to reopen prosecution:

• (A) An examiner’s answer that designates a new ground of rejection pursuant to 37 CFR 41.39 (see MPEP § 1207.03); or
• (B) A substitute examiner’s answer responding to a remand by the Board for further consideration of a rejection pursuant to 37 CFR 41.50(a) (see MPEP § 1207.05). Such a substitute examiner’s answer may contain a new ground of rejection (also see MPEP § 1207.03).

If a reply brief is filed in response to a substitute examiner’s answer under 37 CFR 41.50(a) that was written in response to a remand by the Board for further consideration of a rejection, any reply brief accompanied by an amendment, affidavit or other evidence will be treated as a request that prosecution be reopened before the examiner. If appellant fails to file a reply brief or a reply under 37 CFR 1.111 within two months from the mailing of the examiner’s answer that contains a new ground of rejection, or a substitute examiner’s answer under 37 CFR 41.50(a), the appeal may be dismissed. See MPEP § 1207.03 and § 1207.05.

After receipt of a reply brief under 37 CFR 41.41, jurisdiction over the appeal passes to the Board. Normally, the examiner does not need to acknowledge the reply brief and will not have an opportunity for further argument prior to a decision by the Board. However, the Board may remand the appeal to the examiner to furnish a substitute examiner’s answer responsive to the remand.
