Perhaps I don't understand patent law, but Patent #6,563,415 "Analog sensor(s) with snap-through tactile feedback" was filed in 9/18/2001 and issued in 2003. Nintendo GameCube was released on September 14, 2001 in Japan, FOUR DAYS BEFORE THIS WAS FILED. If a patent is to retain the rights to a new, novel idea, then the marketplace demonstrates why this patent is invalid and should not have been issued, as the idea was already out there.
Also, what the heck does "clogging the channel" mean. Does this company really suggest that Nintendo prevented them from releasing their own controller? If Nintendo hadn't "infringed" on this patent, Anascape would not have released a controller for the GmaeCube with this function because no games would support it. Would Anascape have released its own gaming system? And did it REALLY take you four+ years to realize that this controller infringed on your rights...or did you just wait until it looked like a profitable lawsuit venture, what with Wii's success? *sigh*
