Firm partner Mike Heim and associate Chris Limbacher scored the victory with a December 2, 2022, ruling issued by the U.S. Patent & Trademark Office's Patent Trial and Appeal Board in Washington, D.C. The case before the PTAB is Apple Inc., LG Electronics, Inc., and Samsung Electronics Co., Ltd., Petitioners, v. Arigna Technology Ltd., Patent Owner, IPR2022-01037. The 24-page decision denied the inter partes review petition on all claims related to Arigna's U.S. Patent No. 8,947,164.
