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.

Best Buy is the newest defendant in Comarco’s recent litigation campaign. Similar to the NPE’s suit last month against Apple, the recent complaint accuses power adaptors sold by Best Buy of infringing two asserted patents. The manufacturers of those products are not named defendants. The complaint asserts two patents relating to a power supply system that converts incoming voltage to DC (7,460,381, 7,863,770). One of those patents (‘770) was asserted in a previous litigation against Targus; the other has not been previously asserted. A separate patent related to power supply was asserted in the earlier case against Apple.
