37 CFR 41.39 Examiner’s answer.
(1) Reopen prosecution. Request that prosecution be reopened before the primary examiner by filing a reply under § 1.111 of this title with or without amendment or submission of affidavits (§§ 1.130, 1.131 or 1.132 of this of this [sic] title) or other Evidence. Any amendment or submission of affidavits or other Evidence must be relevant to the new ground of rejection. A request that complies with this paragraph will be entered and the application or the patent under ex parte reexamination will be reconsidered by the examiner under the provisions of § 1.112 of this title. Any request that prosecution be reopened under this paragraph will be treated as a request to withdraw the appeal.
(2) Maintain appeal. Request that the appeal be maintained by filing a reply brief as set forth in § 41.41. Such a reply brief must address as set forth in § 41.37(c)(1)(iv) each new ground of rejection and should follow the other requirements of a brief as set forth in § 41.37(c). A reply brief may not be accompanied by any amendment, affidavit (§§ 1.130, 1.131 or 1.132 of this of this [sic] title) or other Evidence. If a reply brief filed pursuant to this section is accompanied by any amendment, affidavit or other Evidence, it shall be treated as a request that prosecution be reopened before the primary examiner under paragraph (b)(1) of this section.
MPEP § 1207 through § 1207.05 relate to preparation of examiner’s answers in appeals. The procedures covered in these sections apply to appeals in both patent applications and patents undergoing ex parte reexamination proceedings, except as provided for in this Chapter. For example, there is no requirement for pre-appeal conferences in reexamination proceedings but there is a requirement for panel review of the examiner’s answer.
After receipt of a reply brief in compliance with 37 CFR 41.41 or the expiration of the time in which to file such a reply brief (37 CFR 41.35), 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 comment 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 or the Director may remand the proceeding under 37 CFR 41.35(c), such as where there has been a change of law that would require that a new ground of rejection be considered. See 37 CFR 41.50(a)(2) and MPEP § 1207.05 for information on substitute examiner’s answer. A substitute examiner’s answer is not permitted unless the reexamination proceeding has been remanded by the Board or Director for such purposes.
