In Ascend Performance Materials Operations LLC v. Samsung SDI Co., Ltd. (Nov. 1, 2021)
In Ascend Performance Materials Operations LLC v. Samsung SDI Co., Ltd., Samsung SDI argued that the Patent Trial and Appeal Board (PTAB)’s final written decision was improper on several grounds and petitioned the Director to review the decision. The Director granted Samsung SDI’s request regarding the argument that the PTAB should have separately considered two claims that had an earlier priority date and antedated the prior art. The Director thus vacated the PTAB decision
