Panasonic North America

I'll verify the company's profile with web searches.

Let me verify the parent's corporate history and the specific tracked case.

Panasonic North America (also styled Panasonic Corporation of North America) is the principal North American subsidiary of Panasonic Holdings Corporation, the Osaka, Japan–based electronics group listed on the Tokyo Stock Exchange (TYO: 6752). The North American unit dates to 1959, when Panasonic's first overseas sales company was established; it has been headquartered at Two Riverfront Plaza in Newark, New Jersey since 2011. Parent Panasonic was founded in 1918 by Kōnosuke Matsushita, incorporated as Matsushita Electric Industrial Co., Ltd. in 1935, renamed Panasonic Corporation in 2008, and reorganized as Panasonic Holdings Corporation in 2022. Panasonic Holdings reported roughly $53B in trailing-twelve-month revenue and about $69B market capitalization (PitchBook, 2026), with ~250,000 employees globally; the North American arm reports on the order of 14,000 U.S. employees and ~$13B in North American annual revenue (NJ.com, 2022). Employee/revenue estimates for the regional unit vary by source and are not audited disclosures.

Operations span several lines: lithium-ion EV batteries through Panasonic Energy of North America (including the Nevada Gigafactory joint venture with Tesla); commercial refrigeration and cold-chain equipment for retail; automotive infotainment, ADAS, and head-up displays; avionics and in-flight entertainment (Panasonic Avionics, Lake Forest, CA); and B2B systems including projectors, professional displays, security cameras, rugged Toughbook computers, POS systems, and factory-automation equipment. Consumer products such as ovens and digital cameras remain a smaller part of the portfolio.

The tracked data shows one case, as defendant, and zero as plaintiff — the profile of an operating company being sued, not a patent assertion entity. Panasonic is a large, product-practicing manufacturer whose patents are used defensively and in cross-licensing; nothing in the record suggests NPE-style assertion activity.

The sole tracked matter, MediaTek, Inc. v. Matsushita Electric Industrial Co., Ltd. et al. (E.D. Tex., filed 2005-10-17), arose from a 2005–2007 DVD/optical-disc chip dispute: Matsushita first sued MediaTek in the Northern District of California, and MediaTek countersued in the plaintiff-friendly Eastern District of Texas. Public reporting indicates the patents concerned video decoding, PLL clock generation, and DVD-related IC technology; a Matsushita motion to dismiss was denied in June 2007. Note the named defendant is the Japanese parent's former name, not the U.S. subsidiary itself.
