InvenSense Files Answer And Brings Its Own Counterclaims Against STMicroelectronics

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. (“ST”) in the U.S. District Court for the Northern District of California in response to what it believes are meritless allegations by ST of patent infringement in relation to InvenSense’s innovative MotionTracking™ devices and gyroscope products. 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”). As set forth in its counterclaims, InvenSense alleges that these patents are infringed by ST 3-axis gyroscope products.
