'Guitar Hero' maker files patent suit

By EDVARD PETTERSSON
BLOOMBERG NEWS

Activision Inc., the second-largest U.S. video-game publisher, claimed in a lawsuit that its "Guitar Hero" game doesn't infringe a Gibson Guitar Corp. patent for creating a "simulated musical concert experience."

Activision, in a complaint filed Tuesday in federal court in Los Angeles, seeks court orders that it doesn't infringe the technology and that the Gibson patent isn't valid.

The company, which is based in Santa Monica, Calif., brought the lawsuit after it was told by Nashville, Tenn.-based Gibson to get a license or stop selling "Guitar Hero," according to the complaint.
