TECHNOLOGY LIVE:More notes on video games

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.
