PalTalk Holdings LLC v. Sony Computer Entertainment America Inc. et al

HPC and co-counsel from Susman Godfrey represented PalTalk in its patent litigation against Sony and Activision-Blizzard. The lawsuit concerned online multiplayer video games such as World of Warcraft and recent titles in the Call of Duty franchise. PalTalk’s asserted patents describe a method for maintaining a consistent game state for each player in the online multiplayer environment. The case settled in September 2011 when Activision-Blizzard and Sony obtained a license to PalTalk’s technology on confidential terms.

Prior to the case against Sony and Activision, HPC and its co-counsel successfully asserted the same patents in a suit against Microsoft relating to the Halo video game franchise. The Microsoft case settled in March 2009.
