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.
