Gibson filed the suit back in 2008, claiming EA and Viacom had infringed upon "a patent issued in 1999 for a way of using a musical instrument to take part in a simulated concert." At the time, Harmonix responded by citing notable differences between the Rock Band franchise and Gibson's patent that had been filed a decade prior.

On June 4, the companies informed the federal court judge overseeing the case that a "full settlement" had been reached, and that they plan to have the suit dismissed by June 14. The exact terms of the settlement have not been disclosed.

Activision was also implicated in a similar lawsuit regarding to its Guitar Hero franchise--also created by Harmonix--but likewise settled with Gibson last year.
