Comarco Patents at Issue in New USB Charging Campaign

June 8, 2021

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.
