In early October, five entities recorded a security interest in the patents each respectively holds, naming as the secured party the same Delaware LLC, with a name suggestive of the involvement of third-party litigation funding. Two of the entities launched litigation later in October, one of them already had active litigation underway, the sole case of a fourth closed back in 2012, and the fifth one does not appear ever to have litigated a patent—yet.

W&Wsens Devices, Inc. has filed an Eastern District of Texas complaint against Samsung (2:24-cv-00854), alleging infringement of five patents described as generally related to “semiconductor photodetectors”. With four of those patents, the inventor-controlled plaintiff targets the provision of CMOS image sensors, as well as products (e.g., computers, digital cameras, smartphones, and tablets), including those of Samsung and those manufactured by third parties Alphabet (Google) and Motorola, incorporating those sensors. With the fifth patent, W&Wsens Devices targets the provision of “Time-of-Flight” (ToF) CMOS image sensors.
