Renesas Electronics Corp. — patent litigation as defendant

I'll research Renesas Electronics Corp. to verify its profile and products.

Let me check the specific litigation context and CommWorks Solutions.

Renesas Electronics Corporation (TSE: 6723; ADR: RNECY), commonly "Renesas," is a Japanese semiconductor maker headquartered at Toyosu Foresia, Koto-ku, Tokyo. It was founded November 1, 2002 per company data, with today's entity formed in April 2010 by the merger of NEC Electronics and Renesas Technology (the latter combining Hitachi and Mitsubishi Electric semiconductor units). It is publicly listed on the Tokyo Stock Exchange Prime Market; it was majority-owned by Japan's Innovation Network Corporation of Japan (INCJ) after a 2013 recapitalization but is now widely held. Recent filings indicate roughly 21,600 employees and revenue in the ¥1.3–1.5 trillion range (about $9–10 billion), per LSEG/FT and MarketWatch profiles.

Renesas designs, manufactures and sells semiconductor products across two reporting segments — Automotive and Industrial/Infrastructure/IoT. Key lines include RL78, RX, RA, RH850 and RZ microcontrollers and microprocessors; R-Car automotive SoCs; analog, power-management and mixed-signal ICs; timing, memory-interface and connectivity products (including Wi-Fi/Bluetooth SoCs such as DA16200 and CL8000-class devices). The RH850 automotive MCU family alone has shipped over 4 billion units since 2013, per Renesas. Growth has come partly through acquisitions including Intersil, Integrated Device Technology, Dialog Semiconductor, Celeno, Reality AI, Steradian and Altium (announced 2024).

Litigation posture: Renesas is an operating company and, in the tracked data, a pure defendant — 0 plaintiff cases and 1 defendant case. That single suit, CommWorks Solutions, LLC v. Renesas Electronics Corp. (E.D. Tex.), fits the classic pattern of an operating semiconductor vendor defending against an NPE assertion.

Notable case/context: CommWorks Solutions is characterized by Unified Patents as an NPE and subsidiary of IP Investments Group LLC. The complaint accuses Renesas Wi-Fi SoCs and reference designs of infringing patents covering Wi-Fi Multimedia (WMM), Wi-Fi Protected Setup (WPS) and Wi-Fi Mesh functionality. The Eastern District of Texas is a plaintiff-favored venue. CommWorks has filed similar Wi-Fi/network patent suits against other chipmakers and networking vendors (e.g., STMicroelectronics, Extreme Networks). No merits determinations in the Renesas case are public.
