What is the time limit for filing an appeal in an inter partes reexamination proceeding?
According to MPEP 2683, the time limit for filing an appeal in an inter partes reexamination proceeding is specified in 37 CFR 1.304(a)(1):
“The time for filing the notice of appeal to the U.S. Court of Appeals for the Federal Circuit (§ 1.302) or for commencing a civil action (§ 1.303) is two months from the date of the decision of the Board of Patent Appeals and Interferences. If a request for rehearing or reconsideration of the decision is filed within the time period provided under § 41.52(a), § 41.79(a), or § 41.127(d) of this title, the time for filing an appeal or commencing a civil action shall expire two months after action on the request.”
It’s important to note that this two-month period is not extendable under 37 CFR 1.136.
