In terms of patent litigation, Lemko Corporation appears to be an operating company asserting its intellectual property. The company has one tracked case, Lemko Corporation v. AT&T Inc. et al., where it is listed as the plaintiff. This lawsuit, filed in the U.S. District Court for the Eastern District of Texas on March 17, 2025, alleges that AT&T is unlawfully utilizing Lemko's patented mobile network innovations. Lemko claims to have presented its network solution to AT&T for several years, with AT&T acknowledging the technology met their goals, but declining a commercial partnership and allegedly infringing upon Lemko's patents. The patents asserted in this case include U.S. Patent Nos. 7,840,230; 7,979,066; 8,224,322; 8,310,990; 8,340,667; 8,359,029; and 9,198,020, which cover aspects of their Distributed Mobile Architecture and network management.
