Comarco Wireless Systems LLC (CWS), an NPE associated with AppBrilliance, Inc., has begun litigating the portfolio of nearly 40 patents that it acquired from Comarco, a defunct operating company turned NPE that appears to have ceased operations between late 2012 and early 2013. In June 2019, CWS sued Samsung (2:21-cv-00208) in the Eastern District of Texas. The plaintiff asserts three patents, broadly directed to supplying power to a portable electronic device, with infringement allegations targeting the provision of devices (e.g., Chromebooks, laptops, and power adapters) that are compliant with certain USB Battery Charging specifications.
