Walker Digital Sues Zynga, Activision Blizzard Over Gaming Patent

Walker Digital, the “invention company” founded by Priceline.com co-inventor Jay S. Walker, isn’t just suing Facebook, he’s also trying to take on some giant game publishers.

More specifically, Walker Digital has just filed a patent infringement lawsuit against Zynga, Activision and the latter’s subsidiary Blizzard Entertainment.

As you can see in the complaint embedded below, the patent-in-suit is U.S. patent no. 6,425,828, which was issued on July 30, 2002. The patent is entitled ‘DATABASE DRIVEN ONLINE DISTRIBUTED TOURNAMENT SYSTEM’.

Walker Digital argues that this gaming patent concerns a product and method of distributed electronic tournaments for a plurality of players that exchanges information with a central controller to influence game play while a player plays in the tournament, and stores player information to influence game play in a subsequent tournament.

According to the “invention company”, a whole slew of games from the aforementioned publishers, including Zynga’s Mafia Wars, Wolfenstein, the Call of Duty series and World Of Warcraft, among others, infringe on the patent.
