Wii accused of patent infringements!!!

The hillcrest device uses MOTION detected via MEMS to control the on screen selection and does not need to see the screen to select. The Wiimote uses infrared sensor / emitters to control the on screen selection and requires the screen to be pointed at (or, more accurately, the sensor bar) for the selection. There is no patent infringement. Hillcrest management should do their homework instead of wasting money on legal maneuvers.

If this is the case, it should be a slam dunk for Nintendo.  The Wiimote does use IR detection for the pointer function.  However, I believe that the Wiimote uses MEMS gyroscopes to do the motion detection.  That may be the basis of the lawsuit.  That seems like a weak arguement to me though.  Gyroscopes have been used to sense motion of decades.  MEMS gyroscopes are just smaller gyroscopes.
