Patent Case Summaries | Week Ending March 11, 2022

A weekly summary of the precedential patent-related opinions issued by the Court of Appeals for the Federal Circuit and the opinions designated precedential or informative by the Patent Trial and Appeal Board.

Broadcom Corp. v. ITC, Nos. 2020-2008, 2021-1260, -1362, -1511 (Fed. Cir. (ITC and PTAB) Mar. 8, 2022). Opinion by Lourie, joined by Hughes and Stoll.

Broadcom filed a complaint at the ITC alleging that Renesas Electronics violated 19 U.S.C. § 1337 by infringing two patents owned by Broadcom. As to the first patent, the ALJ held that Broadcom failed to satisfy the technical prong of the domestic industry requirement and failed to prove infringement. As to the second patent, the ALJ held that the asserted claim would have been unpatentable as obvious over certain prior art. The Commission affirmed, and Broadcom appealed.
