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.
