Microsoft sued for patent infringement over Kinect controller tech

Microsoft is being sued for patent infringement over motion-sensing technology used in its blockbuster gaming accessory, the Microsoft Kinect. Ohio-based Impulse Technology has filed a complaint alleging that Microsoft’s Kinect controller infringes on seven of its technology patents. One patent referenced in the lawsuit covers “wide variety of games where the movement of a player is tracked in three dimensions…and certain exercise games where the motion of the player is tracked to effect movement of a virtual avatar, and the exertion of the user is monitored, including where the tracking of the player is done by the use of a camera.” A separate patent describes an “education system challenging a subject’s physiologic and kinesthetic systems to synergistically enhance cognitive function.” Impulse Technology is seeking a permanent injunction to block the import and sale of Microsoft’s Kinect, and it is also suing Electronic Arts, Konami and Sega for developing Xbox 360 games that utilize Kinect and infringe on its patents. Impulse is seeking damages, treble damages, interest, and attorney fees from Microsoft as well. The Kinect motion-based video game controller has been a smash hit for Microsoft, having set numerous sales records since its launch. This past March, Microsoft announced that it had sold 10 million Kinect controllers since the device’s launch just before the holidays last year.
