CAFC Dismisses Inter Partes Reexamination Appeal By a Party Who was Not Initial Requester

Waters argued that Agilent could not appeal, because Aurora was the third-party requester of the reexamination, not Agilent. The Court held that the relevant question was whether Agilent was a member of a class of litigants that may enforce a legislatively created right under 35 U.S. C. § 141 (reexamination appeals). If so, that party has a ‘cause of action’ under the statute, and this cause of action was a necessary element of his ‘claim.’ See Davis v. Passman, 442 U.S. 228, 239 (1979). The Court held that both 35 U.S. C. § 141 and 35 U.S. C. § 315(b) confirm that the right to appeal an adverse reexamination decision is reserved only to patent owners and third-party requesters.
