Seems Gibson, maker of fine guitars, feels Activision is infringing a patent it holds around guitar simulations.

It seems, however, that Gibson isn’t at all satisfied with the arrangement it has with Activision. Gibson has sent a notice to Activision declaring that the games publisher is infringing upon the guitar maker’s patent for a concept similar to Guitar Hero.

U.S. Patent number 5990405 awarded to Gibson in 1999 read, “A musician can simulate participation in a concert by playing a musical instrument and wearing a head-mounted 3D display that includes stereo speakers. Audio and video portions of a musical concert are pre-recorded, along with a separate sound track corresponding to the musical instrument played by the musician.”

I wonder if this means GH4 will come with a sweet plastic PRS?
