W&W Sens Devices Inc.

W&W Sens Devices Inc. is a privately held company founded in 2014 and headquartered in Los Altos, California. The company has raised $5.3 million in funding. Its key leadership includes co-founders Shih-Ping "Bob" Wang (CEO & CFO) and Shih-Yuan Wang (CTO), both of whom also serve as inventors on the company's patents.

W&W Sens Devices Inc. develops photodetector technology, specifically thin silicon photosensors with high near-infrared (NIR) sensitivity. Their "lightwave trapping using microholes" innovation aims to enable high-speed and high-sensitivity photosensor arrays for various applications, including visible/NIR imaging, 3D imaging (Time-of-Flight), AR/VR, facial recognition, LiDAR for ADAS, security, and medical devices. The technology is also geared towards high-capacity optical interconnects for data centers. W&W Sens Devices Inc. states their IP portfolio includes 56 issued patents and published patent applications.

W&W Sens Devices Inc. primarily appears as a defendant in patent litigation, with one tracked case. This case, Samsung Semiconductor Inc. et al. v. W&W Sens Devices Inc., is a Post-Grant Review proceeding at the Patent Trial and Appeal Board (PTAB), initiated on June 20, 2025. This indicates W&W Sens Devices Inc. is defending its patent(s) against a challenge from Samsung. The company has also been a plaintiff in a District Court case against Samsung in the Eastern District of Texas, alleging infringement of five patents related to "semiconductor photodetectors," specifically targeting CMOS image sensors and Time-of-Flight CMOS image sensors found in products like smartphones and digital cameras. Samsung has filed counterclaims in this district court case.

The PTAB case follows W&W Sens Devices Inc.'s patent infringement lawsuit filed against Samsung Electronics Co., Ltd. and its subsidiaries in the Eastern District of Texas on October 21, 2024. The asserted patents are generally related to "semiconductor photodetectors." Samsung's motion to stay the district court case pending inter partes review (IPR) and post-grant review (PGR) for the asserted patents was denied without prejudice, as the PTAB had not yet instituted review for any of the patents at that time.
