Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | 1. Organization Comarco, Inc., through its wholly-owned subsidiary Comarco Wireless Technologies, Inc. (collectively, “we,” “our,” “Comarco,” or the “Company”), is a developer and designer of innovative technologies and intellectual property currently used in power adapters to power and charge battery powered devices such as laptop computers, tablets, smart phones and readers. Our operations consist solely of the operations of Comarco Wireless Technologies, Inc. (“CWT”), which was incorporated in the state of Delaware in September 1993. Comarco, Inc. was incorporated in California in 1960 and its common stock has been publicly traded since 1971 when it was spun-off from Genge Industries, Inc. Our business targets the needs of today’s mobile culture by providing innovative charging solutions for the myriad of battery powered devices used by nearly all consumers today. Our innovative technology allows the consumer to charge multiple devices from a single charger, eliminating the need to carry multiple chargers while traveling. This technology was developed by Comarco and we own an extensive patent portfolio related to this technology. Our patent portfolio is the result of years of research and development to provide charging solutions. We continue to develop new technologies and expand our patent portfolio, while concurrently exploring other ways to capitalize on this strategic asset.
