TechRadium, a Texas-based developer of mass notification systems, filed a complaint Tuesday in Houston federal court alleging that Twitter infringes on its patented technology. The dispute arose after TechRadium learned that municipal governments were considering using Twitter for public emergency alerts. TechRadium seeks economic damages and a permanent injunction barring Twitter from infringing on its patents.
