Samsung Electronics Co., Ltd.—which had successfully petitioned for IPR—withdrew from the case after Huawei filed its appeal, but the U.S. government intervened to defend the PTAB’s decision.

Substantial evidence supported the Patent Trial and Appeal Board’s findings that a relevant artisan would have found obvious the claims of a patent directed to enabling a mobile communication device to gain access to a 2G/3G network using a temporary identifier existing in a 4G network, the U.S. Court of Appeals for the Federal Circuit has held. The patent at issue was held by Chinese telecommunications company Huawei Technologies Co., Ltd. The court affirmed the Board’s final decision that the challenged patent was invalid (Huawei Technologies Co., Ltd. v. Iancu, June 4, 2020, Taranto, R.).

Case date: 04 June 2020
Case number: No. 19-1497
