Activision has made a formal statement about its lawsuit against Gibson Guitar Corporation's patent claim on Guitar Hero. Activision calls Gibson's squeeze-play a "transparent end run ... on patent assertions that Gibson knows have no merit." According to Activision, Gibson waited three years until this past January to make its patent allegations and only did so after Activision said it was no longer interested in renewing its "marketing and support agreement with Gibson."

Poor Gibson, looks like it's just a little bitter about (Warning: double cliché alert) not seeing the light on its patent many moons ago and missing the boat on a billion dollar franchise. Meanwhile, Harmonix is still making money off the franchise it lost and is currently working out a deal with Activision over the $14.5 million the company says it's due in royalty fees.
