Gibson Sues U.S. Retailers Over Guitar Hero Patent Dispute
Text of Patent No. 5,990,405 (November 23, 1999)
As previously reported: (i) in January, Gibson pressed Activision to pay it royalty fees alleging the video game Guitar Hero infringes its patent; and (ii) on March 12, 2008 Activision filed a preemptive lawsuit in the District Court for Central California seeking, among other things, to invalidate Gibson’s patent claims.
In response to Activision’s lawsuit, Gibson has now filed suit against major U.S. retailers of Activision’s game, including GameStop, Wal-Mart, Target, Kmart, Amazon and Toys “R” US, seeking to enjoin further sails of “Guitar Hero”.
March 21, 2oo8 Upate: While Gibson has since separately sued Harmonix, MTV and EA over alleged infringements in both Guitar Hero and Guitar Hero, as far as I’m aware Gibson has not yet filed suit directly against Activision.
Dale’s Comment: I have not found the text of the claim online. If/when I do, I will attach it to this post.
