MOSAID notes that on April 7, 2011, it had filed suit against NVIDIA Corporation, Freescale Semiconductor, Inc. and Interphase Corporation in the United States District Court for the Eastern District of Texas, Tyler Division, asserting infringement of seven U.S. patents related primarily to power management techniques and microprocessor architecture.
