Guitar Hero games, including GameStop, Wal-Mart, Target, Kmart, Amazon, and Toys "R" Us, seeking to prohibit sales of the games. In a statement released Thursday, the company claimed it took "this action reluctantly, but is required to protect its intellectual property."
Though Gibson has yet to file suit against Guitar Hero owner Activision, the guitar company has made a legal claim alleging that the games (when played with the guitar controllers) violate Gibson's patent for a type of virtual music performance. Subsequently, Activision filed a preemptive lawsuit against Gibson last week, and then publicly dismissed Gibson's patent infringement claim. Most recently, Gibson targeted Guitar Hero creator and former developer Harmonix, its daddy's daddy Viacom and Rock Band co-publisher Electronic Arts for allegedly violating the same patent ... Yeah, our head's spinning too.
