M-Red Inc., a subsidiary of publicly traded NPE Quest Patent Research Corporation (QPRC), has sued Mitsubishi Electric (2:21-cv-00075), Nintendo (2:21-cv-00076), and Xiaomi (2:21-cv-00077) in the Eastern District of Texas. In each complaint, the NPE asserts five patents, two of which are new to litigation; infringement allegations target the incorporation of systems-on-chip (SoCs) manufactured by Amlogic, Broadcom, NVIDIA, Renesas, Qualcomm, and/or themselves in various products (e.g., infotainment systems, projectors, smartphones, game consoles, etc.). At issue is the incorporation of oscillator circuits and the utilization of on-chip temperature sensors for power management. To date, M-Red has asserted six patents in this, its sole litigation campaign, each received in a portfolio of 50 US assets from Intellectual Ventures LLC (IV) in March 2019.
