Matsushita (Panasonic) — Company Profile
Overview. The entity tracked in our database as "Matsushita (Panasonic)" is Matsushita Electric Industrial Co., Ltd., which renamed itself Panasonic Corporation in 2008 and became Panasonic Holdings Corporation (パナソニック ホールディングス株式会社) in 2022 under a holding-company reorganization. It is a publicly listed Japanese multinational, trading on the Tokyo Stock Exchange (TSE: 6752; ADR: PCRFY), headquartered at 1006 Oaza Kadoma, Kadoma, Osaka, Japan. Founded March 7, 1918 by Kōnosuke Matsushita, the group is one of the world's largest electronics manufacturers, with roughly 183,000–228,000 employees depending on reporting date and consolidated net sales of about ¥8.05 trillion (FY ended March 2026).
Products / operations. Panasonic is an operating company, not a patent-assertion entity. Its business segments span consumer electronics and appliances (TVs, refrigerators, washing machines, air conditioners), automotive systems (batteries, infotainment, EV components), industrial solutions (factory automation, electronic components), energy (lithium-ion cells, solar, energy storage), and connected solutions (aviation, professional AV, housing). Battery and automotive operations are among its largest growth areas.
Litigation posture. The case data shows zero plaintiff cases and two defendant cases — the profile of an operating company being sued, not an aggressor. Both tracked matters are U.S. District Court, Eastern District of Texas (Marshall Division) suits brought by Technology Properties Ltd. / the TPL Group, a patent-licensing enterprise asserting the Moore Microprocessor Patent (MMP) portfolio (U.S. Patent Nos. 5,809,336; 6,598,148; 5,784,584). The Marshall Division is a historically plaintiff-friendly venue, and TPL chose it specifically for its speed.
Notable context. The tracked cases correspond to Technology Properties Ltd., Inc. v. Fujitsu Limited et al. (No. 2:05-cv-00494, filed Oct. 24, 2005), in which Matsushita Electric Industrial, Panasonic Corporation of North America, and co-defendants Fujitsu, NEC, Toshiba, and JVC were accused of infringing MMP patents covering on-chip clocking and instruction-group microprocessor architecture. The two entries in our list appear to reflect the same underlying dispute (TPL/TPL Group v. Fujitsu et al.). Co-defendant ARM intervened in 2006 and won a Federal Circuit non-infringement ruling on the '584 patent in 2008; the '584 patent claim was also held invalid in reexamination. Other defendants, including Fujitsu, settled and took MMP licenses.
