Matsushita Industrial Electric Co., Ltd. — Company profile
Overview. In the only tracked U.S. patent case, this entity is identified as a corporation organized under the laws of Japan with its principal place of business at 1006 Oaza Kadoma, Kadoma City, Osaka 571-8501, Japan (complaint, Digital Security Systems Corp. v. Samsung Electronics, E.D. Tex. No. 2:08-cv-00316). That address is the historic Kadoma headquarters of the Panasonic/Matsushita group. In its 2008 corporate disclosure statement the defendant identified no corporate parent, and it separately filed a notice of change of corporate name in late 2008 — timing consistent with the group-wide rebranding in which Matsushita Electric Industrial Co., Ltd. became Panasonic Corporation on October 1, 2008 and hundreds of affiliates dropped the "Matsushita"/"National" names. I could not independently verify a standalone website, employee count, revenue, or incorporation date for this specific entity, and the name may be a pleading variant of Matsushita Electric Industrial Co., Ltd. (now Panasonic).
Products / operations. I found no verified record of independent operations under this exact name. If it is a Panasonic group affiliate, the relevant parent's business spans consumer electronics and home appliances, AVC/network products (flat-panel TVs, DVD/Blu-ray players), automotive electronics and cellular phones, components and devices, batteries, and factory-automation equipment. I cannot confirm which lines this named entity itself supplied, so this is offered as parent-level context only, not as its own product list.
Litigation posture. Operating-company defender, not an asserter: 0 plaintiff cases, 1 defendant case in the data. The single appearance is as a co-defendant sued by Digital Security Systems Corporation, LLC, an Acacia Research Corporation subsidiary, in the Eastern District of Texas, Marshall Division — a plaintiff-friendly venue typical of NPE filings.
Notable case. Digital Security Systems Corporation, LLC v. Samsung Electronics Co., Ltd. et al., filed August 11, 2008, asserted U.S. Patent No. 6,052,780 ("Computer System and Process for Accessing an Encrypted and Self-Decrypting Digital Information Product"). Co-defendants included Samsung, Best Buy, D&M/Denon, Funai, LG, Panasonic Corporation of North America, Philips, Pioneer, and Sharp — a Blu-ray/optical-media product focus. Matsushita shared counsel with Panasonic Corporation of North America.
