In 2008, Guitar Hero is one of the biggest revenue generators in games. Red Octane got bought by Activision. Harmonix got bought by MTV and came out with their own version, Rock Band. Activision, as the biggest game company on the planet, decided they didn't want to pay the licensing fees to Gibson anymore and canceled the contract. Gibson then sued Activision in Tennessee, saying that the Guitar Hero controllers violated a patent that they held and asked for boku bucks. They even let everyone know this was just Phase 1. They were looking at suing Harmonix over Rock Band next, and even threatening retailers who sold the games. Activision asked the US District Court in California to toss the suit and prevent Gibson from persuing damages. Tennessee put the case on hold pending the outcome of the US District Court.
On Thursday, the US District Court tossed the suit and prevented Gibson from persuing damages. "No reasonable person of ordinary skill in the relevant arts would interpret the '405 Patent as covering interactive video games. Gibson would have this Court determine that any device that controls something that produces musical sounds is covered by the '405 Patent." So sayeth Judge Mariana R. Pfaelzer.
Given how nuts patent suits are, especially when used as an anti-competitive weapon or just payback (hence the Tux icon instead of a general video gaming icon), this is a breath of fresh air.
