Activision has begun litigation against Gibson to settle whether the Guitar Hero franchise is infringing against Gibson's patent for a "technology used to simulate a musical performance." Activision is seeking a judgment to remove Gibson's claim for licensing fees. It is interesting that Activision and Gibson are already partners, with Gibson supplying the designs for GH's guitars. Activision thought it had its bases covered by purchasing or licensing many patents already before the release of GH III. Oh! It looks like one of Gibson's periscopes is just peeking its head out of the water right now!
Gibson wants a bigger piece!
This case just goes to show how hard it is for a successful video game company to navigate the patent waters - Gibson's U-Boats are all around! Activision seems to be enjoying the flip-side of success - everyone coming out the woodwork saying, "You owe me!"
