InvenSense, Inc. (NYSE:INVN), the leading provider of MotionTracking™ devices for consumer electronic products, today announced it has filed an answer and counterclaims against STMicroelectronics, Inc.

In its answer and counterclaims, InvenSense denies infringement and validity of the nine patents asserted by ST in a complaint filed on May 16, 2012. In addition, InvenSense has brought its own counterclaims against ST for alleged infringement of two InvenSense patents, U.S. Patent No. 7,290,435 (“Method and Apparatus for Electronic Cancellation of Quadrature Error”) and U.S. Patent No. 7,458,263 (“Method of Making an X-Y Axis Dual-Mass Tuning Fork Gyroscope with Vertically Integrated Electronics and Wafer-Scale Hermetic Packaging”).
