1 case as defendant.
ON Semiconductor Corporation (onsemi) — Legal name ON Semiconductor Corporation, which operates under the "onsemi" brand; incorporated in Delaware in 1992 and spun off from Motorola's semiconductor business in 1999. Publicly traded on Nasdaq (ticker: ON). Headquarters: Scottsdale, Arizona. FY2024 revenue was approximately $7.08 billion, with roughly 22,600–26,500 employees depending on reporting date (a 2024 restructuring reduced headcount). No parent company.
Products / operations. onsemi designs and manufactures semiconductors positioned as "intelligent power and intelligent sensing" solutions, organized into three segments: Power Solutions Group (discrete power devices, MOSFETs, IGBTs, SiC devices, power modules), Analog & Mixed-Signal Group (power-management ICs, gate drivers, analog and mixed-signal ICs), and Intelligent Sensing Group (CMOS image sensors, image signal processors, SPAD/SiPM photodetectors, actuator drivers). Automotive is its largest end market (~60% of 2024 revenue), followed by industrial (~24%). The company acquired Fairchild Semiconductor in 2016. This is an operating company with real products, not an NPE.
Patent-litigation posture. Per the tracked data, onsemi appears in one case as a defendant and zero as a plaintiff — the profile of an operating company being sued rather than a patent asserter. Its sole tracked case is a NPE suit, not two-way litigation.
Notable case. Cedar Lane Technologies Inc. v. ON Semiconductor Corp., filed in the Western District of Texas (Austin Division, 1:20-cv-00414). Cedar Lane is a Canadian patent-assertion entity founded around 2019 that acquires patents — including portfolios originating with Intellectual Ventures/AVInnov — and has filed hundreds of suits, frequently in W.D. Tex. and D. Del. The venue is consistent with Cedar Lane's pattern of filing in plaintiff-friendly Texas districts. The tracked record does not indicate the asserted patent or outcome.
