Comarco Wireless Systems LLC (CWS) has revived its sole litigation campaign, launched in June 2021, with a suit against Walgreens (4:23-cv-01111) in the Eastern District of Texas. The asserted patents are broadly directed to a system for suppling power to a portable electronic device, with the defendant accused of infringement through the provision or sale of certain Infinitive- and Belkin-branded charging cables, charging devices, and power banks. At issue are the products’ compliance with the Battery Charging (BC) 1.2 specification.

Comarco Wireless Systems LLC (CWS) has expanded its sole litigation campaign with suits against Anker (2:22-cv-00266) in the Eastern District of Texas and Lenovo (5:22-cv-00273) in the Eastern District of North Carolina. The asserted patents generally relate to supplying power to a portable electronic device, with the defendants accused of infringement through the provision of “portable electronic devices” (i.e., computers, data hubs, laptops, and power banks) equipped with rechargeable batteries and USB-C ports, as well as certain power adapters. At issue are the products’ compliance with certain USB standards.

On April 20, 2022, Texas plaintiff Comarco Wireless Systems LLC (CWS) filed its second lawsuit, accusing LG Electronics (LGE) infringing three power supply patents. RPX reported on April 25 that the Northern District of Texas complaint was accompanied by a document characterized as a “certificate of interested parties” that provided only the basic filing party disclosure—indicating that CWS has no “parent corporation” and “that no publicly held corporation owns 10% or more of its stock”—rather than containing “a complete list of all [entities] that are financially interested in the outcome of the case”, as local rules require. Two days later, CWS filed an amended version of its prior “certificate”, which identifies four entities so interested in the case, but the document, even as amended (both versions signed by lead counsel Michael C. Smith of Scheef & Stone, LLP), raises additional questions and comparisons.

Sued this past week in the Northern District of Texas, LG Electronics (LGE) (3:22-cv-00884) has become the second defendant in the litigation campaign of Comarco Wireless Systems LLC (CWS). The plaintiff asserts the same three patents—generally related to suppling power to a portable electronic device—at issue in its June-to-November 2021 case against Samsung, now dismissed with prejudice from the Eastern District of Texas. Per Local Rules 3 and 7, the Northern District of Texas requires plaintiffs to identify “a complete list of all persons, associations of persons, firms, partnerships, corporations, guarantors, insurers, affiliates, parent or subsidiary corporations, or other legal entities that are financially interested in the outcome of the case”. CWS, however, has filed a disclosure indicating only that it has no “parent corporation” and “that no publicly held corporation owns 10% or more of its stock”. Whether properly characterized as a “parent corporation”, AppBrilliance, Inc. is identified in Texas state records as CWS’s managing member.

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.
