Klausner Technologies announced Monday that it has filed suit against the company in everyone's favorite rocket docket, the U.S. District Court for the Eastern District of Texas. Klauser is claiming that the visual voice mail feature infringes on two patents that are said to cover the iPhone's method of selectively listening to voice mail messages rather than in the order in which they were received.

Unlike the other inane iPhone lawsuits filed since the device made its debut in June, Apple might have to take this one a little more seriously. Klausner has already won cases against AOL and Vonage asserting the patents in question here, and is asking for $360 million in royalties and damages.
