Recently, in Google LLC v. Ikongoro Tech. LLC, the Patent Trial and Appeal Board (“the Board” or “PTAB”) instituted inter partes review after it had previously denied the institution of such a review due to the pendency of related district court litigation in the Western District of Texas—a case which was subsequently transferred to the Northern District of California by the Federal Circuit granting mandamus relief.  The Board’s decision casts light on the interplay between the PTAB’s discretion to deny institution of inter partes review and the increased focus on transfers out of the Western District of Texas.

In the recent case of Amgen Inc. v. Sanofi, Aventisub LLC, the Federal Circuit affirmed the district court’s invalidation of certain of Amgen’s antibody patent claims, concluding that the claims were not “enable[d]” under 35 U.S.C. § 112. This decision establishes that it is more difficult to satisfy the enablement requirement for antibody claims that use functional language to describe the antibody. (The court granted Amgen’s motion to extend the deadline for filing a petition for panel rehearing and/or rehearing en banc until April 14, 2021. See id., Order (March 8, 2021).)
