TheStreet is reporting that Keystone Autonics is seeking an injunction, damages and legal fees against both XM and Sirius satellite radio over their patented technology.

The patent in question was awarded to George Hindman of Keystone Autonics in January. It applies to specific input and display processing of wireless data for satellite radios. The patent is actually a modification to an earlier patent (conveniently also held by Hindman) that applied to radios and CD players.

The lawsuit asserts that the patented technology, among other things, helps enable mobile features like global positioning system, or GPS, location services, as well as crash and theft detection functions.
