Two Chinese ETRI video codec patents held invalid after appeals

After the China National IP Administration (CNIPA) invalidated the patents in administrative proceedings, and the Beijing IP Court upheld that invalidation, Electronics and Telecommunications Research Institute (ETRI) filed a second appeal to China's Supreme People's Court. On April 30, 2026, Unified Patents received two judgements where China’s Supreme People's Court upheld the original invalidations on CN103384333B and CN104219523B.

CN'333 and CN‘523 were generally directed to applying the same prediction mode to a unidirectional series of blocks and are related to patents that are designated essential to the Access Advance (formerly known as HEVC Advance) patent pool, as well as, SISVEL’s AV1 and VP9 patent pools.

Unified was represented by Tao Chen, Yu Yan, and Peter Zhang at Wei Chixue Law Firm, and the case was managed by in-house counsel, Jessica L.A. Marks and Roshan Mansinghani.
