Since Guitar Hero made its debut back in 2005 (has it really been that long?) we've been rocking out with various Gibson controllers. I never really cared for the the X-plorer, but that's not the point here. Apparently Gibson has just realized that the Guitar Hero game infringe on one of their patents.
Based on our preliminary analysis, the 'Guitar Hero' software (including any expansion packs) and the guitar controller provided by Activision being used as a musical instrument (packaged with the software or sold standalone) are covered by the ... patent," Gibson's law firm said in its January 7 letter. Gibson requests that Activision obtain a license under Gibson's ... patent or halt sales of any version of the 'Guitar Hero' game software.
