STMicroelectronics Files Section 337 Patent Complaint on MEMS Devices

STMicroelectronics filed a Section 337 complaint March 11 with the International Trade Commission, alleging microelectromechanical systems (MEMS) imported by InvenSense, Roku, and Black & Decker are infringing its patents. MEMS devices are used in portable electronics, power tools, remote controls, and video game controllers to enable these products to sense when they are being rotated, tilted, dropped, or moved in other ways by the user. According to STMicroelectronics, InvenSense directly imports MEMS devices that infringe its patents, while Roku imports remote controls that contain infringing MEMS devices, and Black & Decker imports power screwdrivers that contain infringing MEMS devices. STMicroelectronics is requesting limited exclusion and cease and desist orders against the proposed respondents.
