Impulse Technology, a distributor of wire and cable products, is suing Microsoft over key technologies used by its Kinect motion sensor. Good thing it happened after we had our time with the Kinect open-source driver hack. Impulse claims that Microsoft violated a whopping six patents 6,308,565, 6,430,997, 6,749,432, 6,765,726, 6,876,496, 7,359,121 and 7,791,808, which were granted between 2001 and 2010. No wonder it took so long to fire up the letters to the court.
In fact, the patents describe a system that is very similar to that of Kinect, though the patents do not provide much detail about the actual technology such as the sensors.
