On July 31, 2024, the Beijing Intellectual Property Court (BIPC) confirmed that all claims of Chinese patent CN102256122 were invalid. The CN’122 patent is owned by Dolby International. The claims were initially found invalid by the China National Intellectual Property Administration, but Dolby appealed to the BIPC. CN102256122 was purportedly essential or related to patents purportedly essential to the Access Advance patent pool and SISVEL’s AV1 and VP9 pools.

Unified was represented by Weichixue Law Firm for the appeal, and the case was managed by in-house counsel, Jessica L.A. Marks.
