Suit Alleges Patent Infringement in the World of Warcraft and other Massively Multiplayer Online Role-Playing Games
The Boston Globe recently reported on the filing of a large patent infringement action against some of the largest developers of Massively Multiplayer Online Role-playing Games (MMORPGs). The case was filed in the Eastern District of Texas, which has long been cited as a plaintiff-friendly jurisdiction. Paltalk Holdings is alleging that numerous game studios, in particular Sony, Blizzard, and Turbine, used technology patented by Paltalk. The Boston Globe article explains the technology alleged in the action and how Paltalk has already been able to force Microsoft to settle with Paltalk in an earlier lawsuit.
One of the toughest challenges in designing online multiplayer games is making sure every player sees identical digital playing fields at all times. When a building explodes or a monster appears, it must happen at the same time on thousands of computers scattered around the world. In 2002, Paltalk purchased two patents from a company called HearMe, covering technologies for sharing data among many connected computers so that all users see the same digital environment. Paltalk claims that the data-sharing technologies used in games made by Turbine and the other companies violate those patents.
Paltalk has already defended these patents successfully against industry titan Microsoft Corp. In 2006, the company sued Microsoft, claiming that the multiplayer features of its popular Halo video games violated Paltalk’s patent rights. The case went to trial in Marshall, Texas, in March, but in mid-trial Microsoft settled the matter by paying an undisclosed sum to license the Paltalk patents.
Here are links to the two patents that Paltalk is claiming were infringed: one and two. Thanks to Tyen at the Fires of Heaven Guild Message Board for posting these links.
