On February 10, Synopsis, Inc. v. Mentor Graphics Corp., Nos. 2014-1516, 2015-1530, 2016 WL 520236 (Fed. Cir. Feb. 10, 2016), ruled that the PTAB may select which claims it decides to review in conducting an AIA inter partes review. The court concluded that nothing required the PTAB to review all of the claims challenged in a petition. In dissent, Judge Newman voiced concern about the impact the majority decision might have on patent litigation, noting that it created an “absence of finality” which “negates the AIA’s purpose of providing an alternative and efficient forum for resolving patent validity issues.”
