PalTalk Holdings LLC v. Microsoft, Sony, and Activision-Blizzard
HPC has represented PalTalk Holdings, Inc. in three different lawsuits filed in the Eastern District of Texas. PalTalk is an instant messaging service that provides chat rooms that enable users to communicate via the Internet. In 2006, PalTalk acquired patents that previously were owned by MPath Interactive, a leading provider of on-line game technology. The MPath patents related to multiplayer games played over the Internet, and in particular, to the efficient handling of communications between players that are necessary to maintain a consistent game environment for all players.
With the assistance of HPC, PalTalk began a campaign to enforce the MPath portfolio against companies that make and sell game consoles and/or video games that allow players to participate in multiplayer games using the Internet. In 2006, PalTalk filed a lawsuit for patent infringement against Microsoft based upon the Halo 2 and Halo 3 games and the Xbox gaming system. Subsequently, another lawsuit was filed in 2009 against Sony for its PS3 gaming system and the Everquest on-line game, and against Activision-Blizzard for its Call of Duty games and the World of Warcraft game.
Attorneys at HPC took the lead in the discovery and handling of the patent issues in these cases. The Microsoft lawsuit was favorably settled in the midst of trial, while the claims against Sony and Activision were resolved prior to trial.
