Federal Circuit Upholds Thales Motion Tracking Patent Asserted against U.S. Government for Second Time

The recent Federal Circuit decision in Elbit Systems of America, LLC v. Thales Visionix, Inc. affirmed a final written decision issued by the Patent Trial and Appeal Board (PTAB), which upheld some claims in an inter partes review (IPR) proceeding challenging the validity of Thales’ U.S. Patent No. 6474159, titled Motion-Tracking and issued in November 2002. The patent claims a system for tracking the motion of an object relative to a moving reference frame using a first inertial sensor mounted on the tracked object, a second inertial sensor mounted on the moving reference frame and an element that receives signals from both inertial sensors to determine an orientation of the object relative to the moving reference frame. The resulting invention enables the use of inertial head-tracking systems for platforms including flight simulators and other vehicular applications.
