In Facebook, Inc. v. Windy City Innovations, LLC, No. 2018-1400 (Fed. Cir. Sept. 4, 2020), the Federal Circuit in a re-issued opinion maintained its holding that the text of 35 U.S.C. § 315(c) does not authorize same-party or new issue joinder to an existing IPR but modified the opinion to further expand on the Court’s authority to review the Board’s joinder decision.
