Filed last week, the complaint from Walker Digital accuses Apple of patent infringement alongside the Walt Disney Company, The Weather Channel, The Nielsen Company, Digimarc Corporation, and TV Aura Mobile. Walker Digital hopes to convince a court that the companies are in violation of U.S. Patent No. 6,263,505.

Walker Digital is the owner of the patent entitled “System and Method for Supplying Supplemental Information for Video Programs,” granted by the U.S. Patent and Trademark office in July 2001. It describes a system that synchronizes additional media, such as separate audio or video, with a program that is being played either live or a recording that is being replayed.
