Apple, AT&T and several others involved have been scoped out in a new patent infringement lawsuit, allegedly for their connection in distributing Shazam, a music identification software distributed under the same name for the iPhone and several other mobile devices.

The 8-page complaint, filed Tuesday in Texas, alleges that nearly a dozen tech companies are contributing to infringement of a US Patent for a “Music identification system” established in September of 2005. When Tune Hunter, Inc. lodged its patent application with the USPTO nine years ago, the little-known firm described its invention as a music identification/purchasing system, specifically emulating the method of “marking the time and the name of the radio station in [a] portable device.” This concept is similar to the same technology that made Shazam popular with iPhone and smart phone users.

In its complaint, Tune Hunter does not specify its issues with each individual defendant, but it does charge them with infringement of its patent “by making, using, selling and/or offering to sell, and/or causing others to use [...] music identification systems and/or devices that are covered by one or more claims” of its patent.

The company is seeking that each defendant pay damages, attorneys’ fees and cease from further infringement. Samsung, Napster, Motorola, and LG Electronics are also among some of the defendants named in the suit.
