Texas-based Anascape Ltd. has filed a patent infringement lawsuit against Microsoft and Nintendo for allegedly infringing a number of controller-related technology patents. The suit was filed in the US District Court for the Eastern District of Texas. Anascape, which has no web presence, cited 12 patents filed by "Brad Armstrong" in its claim.
US Patent 5,999,084, granted in 1999 covers a "sensor having a housing" and a depressible actuator in a "resilient dome cap," appearing to cover pressure-sensitive controller buttons. Patents 6,102,802, 6,135,886, 6,343,991, 6,351,205, 6,400,303, and 6,208,271 all basically cover the concept of controllers that include analog pressure-sensitive buttons.
The company also claims that the following patents have been violated: 6,906,700 (3D Controller with Vibration), 6,344,791 (Variable Sensor with Tactile Feedback), 6,347,997 (Analog Controls Housed with Electronic Displays) and 6,222,525 (Image Controller with Sheet Connected Sensors). A patent similar to 6,906,700 (3D Controller with Vibration) held by Immersion Corp. cost Sony millions when it lost a lawsuit brought against it over the company's DualShock technology.
It is interesting that Anascape hasn't targetted Sony with a lawsuit but Ars technica points out that pressure-sensitive buttons were available as early as 2000 with the release of the PlayStation 2 console, for which development probably started before Armstrong even filed his earliest patents. Neither Microsoft or Nintendo have commented about the suit yet.
