Burden of Persuasion for Patentability of Amended Claims in IPR Stays with Petitioner
After a panel of the Federal Circuit affirmed the Board’s decision, in Aqua Products v. Matal, Aqua requested an en banc rehearing. The USPTO Director Joseph Matal joined the appeal on behalf of the USPTO. At issue was whether the Board could place the burden of proof for patentability of amended claims on the patent owner in an IPR, and the Board’s underlying interpretation of the relevant statutes, specifically § 316(d) governing claim amendments and 35 U.S.C. § 316(e) allocating the burden of proof in an IPR… With respect to the burden of proof, the burden of persuasion for patentability of amended claims in an IPR proceeding is placed on the petitioner, not the patent owner. However, considering Judge Reyna’s concurrence, patent owners might still have the burden of production; depending on future cases.
