1 case as defendant.
InvenSense, Inc. is a technology company founded in 2003 and headquartered in San Jose, California. Since being acquired by TDK Corporation for approximately $1.3 billion in 2017, InvenSense operates as a wholly-owned subsidiary within TDK's MEMS Sensors Business Group. As an operating company, InvenSense designs and manufactures Micro-Electro-Mechanical Systems (MEMS) sensor platforms.
The company's primary products are sensor systems on a chip (SoCs) that integrate MEMS-based motion sensors like gyroscopes and accelerometers, as well as microphones. These components are combined with proprietary firmware and algorithms to provide "MotionTracking" and audio solutions. InvenSense technology is used for functions such as motion and gesture interfaces, optical image stabilization, and contextual awareness in a wide range of products, including smartphones, wearables, smart home devices, robotics, and automotive systems.
Based on its legal history, InvenSense is an operating company that defends against patent infringement claims. The company has been tracked as a defendant in one patent case and has not been a plaintiff. This defensive posture is common for technology manufacturers.
The company's single tracked case is Mems Innovations LLC v. TDK Corp et al., filed in the Northern District of California in April 2026. InvenSense is a defendant alongside its parent company, TDK. The plaintiff, Mems Innovations LLC, is an entity that asserts patents it licenses from the Electronics and Telecommunications Research Institute (ETRI) and has filed related suits against TDK in other districts. The case in the Northern District was transferred from the Central District of California.
The accused products are several models of ultrasonic time-of-flight sensors and a related sensor module.
