Defendant
2 cases as defendant.
OS Electronics Co., Ltd. is a technology trading company headquartered in Tokyo, Japan, founded in 1963. As of April 2025, it operates as a wholly-owned subsidiary of Marubeni Corporation. The company specializes in supplying a broad range of semiconductors and electronic components.
OS Electronics' product portfolio includes discrete semiconductors, analog and logic integrated circuits, memory and storage solutions, microcontrollers, sensors, wireless interfaces, and various passive components. They cater to industries such as automotive, industrial automation, consumer electronics, and telecommunications, serving a global customer base across markets in China, India, Singapore, Taiwan, and Japan. The company primarily generates revenue through a business-to-business (B2B) transaction model, which encompasses consulting sales and direct product supply to manufacturers and enterprises.
In terms of patent litigation, OS Electronics Co., Ltd. appears to be an operating company defending against assertions. The company has been involved in one tracked case, "Maxell Ltd. v. OO Electronics Co LTD et al.", as a defendant, initiated on April 21, 2025, in the United States District Court for the Eastern District of Texas. This posture, with zero plaintiff cases and one defendant case, indicates they are a target of patent litigation rather than an entity primarily asserting patents. The Eastern District of Texas is a known venue for patent litigation.
Maxell Ltd. filed this ongoing patent infringement suit against OO Electronics Co LTD and OO Electronics America Inc in the Eastern District of Texas on April 21, 2025, asserting US patent 8471950.
IngenioSpec LLC sued OO Electronics Co LTD and OO Electronics America Inc in the U.S. District Court for the Eastern District of Texas concerning US patents 12044901 and 8582789. The case was dismissed as of June 11, 2025.
