Gibson: Activision's "Guitar Hero" violates patent
SAN FRANCISCO |
SAN FRANCISCO (Reuters) - Gibson Guitar Inc has told Activision Inc (ATVI.O) its wildly popular "Guitar Hero" video games infringe one of Gibson's patents, a claim that Activision has asked a U.S. court to find invalid, according to court documents.
In a letter sent to Activision in January, Gibson said the games, in which players press buttons on a guitar-shaped controller in time with notes on a TV screen, violated a 1999 patent for technology for simulating a musical performance.
On Tuesday, Activision asked the U.S. District Court for Central California to declare Gibson's patent invalid and bar it from seeking any damages.
