On July 22, 2021, in a challenge that took less than 6 months to complete, the China National Intellectual Property Administration declared claims 1, 2, 5, 7, 9, 14, 16 and 18 of CN103081504 invalid. Owned by IdeaHub, Inc., the CN’504 patent is directed to media content streamed in accordance with the MPEG-DASH standard and to video-on-demand (VOD) systems. It is related to U.S. Patent 8,645,562, which IdeaHub's licensee, Helios Streaming, LLC, has used to sue Showtime, Vudu, Crackle, and Starz.

Unified is represented by Fanghua Zhou at Wei Chixue Law Firm, and the case is managed by in-house counsel, Jessica L.A. Marks and Ashraf Fawzy.
