Appeal Jurisdiction Transfers to Board After Reply Brief
Note:
After receiving a compliant reply brief or its deadline, appeal jurisdiction shifts to the Board. The examiner typically does not comment further before the Board's decision.

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.
