On February 7, 2021, Unified filed an invalidity challenge in China against CN103299632, owned by Velos Media. The CN’632 patent is directed to video decoding techniques and was originally assigned to Ericsson before being transferred to Velos. The CN’632 patent is related to EP 2 664 149, which Unified filed an opposition on December 29, 2020. It is also related to U.S. Patent 9,414,066, which Unified has also challenged in the U.S. with IPR2020-00352, instituted on June 30, 2020.

Unified is represented by Jingjing Guo of JZMC Patent and Trademark Agency, and the case is managed by in-house counsel, Jessica L.A. Marks and Roshan Mansinghani.
