The latest target for the Electronic Frontier Foundation's Patent Busting Project comes courtesy of Patent 6,264,560, a patent for a "method and system for playing games on a network." The patent in question is held by Sheldon F. Goldberg and was granted on July 24, 2001, about two years after it was filed. Like many of the patents we cover on Ars, this one make some very broad claims.
Goldberg's patent claims to cover any and all online, multiplayer games that offer real-time updates of player rankings and use tournament-style play. Patent '560 also covers serving up targeted advertising using player demographics.
