On June 29, 2026, in the second appeal of Unified’s challenge of InterDigital’s CN101491099, the Beijing Intellectual Property Court confirmed the invalidity of all challenged claims (1, 2, 5-9, 15, 19-21, 24-28, 34, 38-40, 43-48, 54, 57-59, 62-67, 73, and 76). The CN’099 patent was previously deemed essential in SISVEL’s VP9 and AV1 pools.
Unified was represented by Tao Chen, Yu Yan, and Peter Zhang of the Beijing Wei Chixue Law Firm, and the case was managed by in-house counsel, Jessica L.A. Marks and Roshan Mansinghani.
