I Don't Believe in Imaginary Property writes "The EFF is attacking more bogus patents. This time they're going after the 'method and system of playing games on a network' which covers tournament ladders, online rankings and advertisements. The patent in question has already been asserted against a number of small companies who know that licensing it is cheaper than litigating. Ars Technica's coverage mentions that Netrek looks like a good source of prior art. 'Netrek, an online multiplayer game with origins in the mid 1980s, makes use of much of the same technology described in Goldberg's patent. Much of the code for Netrek is open source, and its development is archived online; the source code was first posted to Usenet in late 1989. The EFF has also documented other instances of prior art with the assistance of students at the Cyberlaw Clinic at the Berkman Center for Internet and Society at Harvard Law School.'"
