Heim, Payne & Chorush LLP Wins Key PTAB Ruling Against Technology Giants Apple, LG Electronics, Samsung
Attorneys from Heim, Payne & Chorush LLP have won a key ruling on behalf of Ireland-based Arigna Technology Limited against electronic giants Apple Inc., LG Electronics, Inc., and Samsung Electronics Co., Ltd.
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.
Arigna sued the Petitioners in 2021 in the Eastern and Western Districts for infringing its patent by manufacturing, assembling, importing, and offering to sell mobile devices incorporating infringing semiconductor devices.
The patent covers novel systems and methods to accurately detect the forward power output of a power amplifier without using large and costly components. Accurate power detection is critical in circuits that include power amplifiers to ensure compliance with Federal Communications Commission (FCC) regulations.
