Contois Music Technology is claiming Apple's iTunes is a patent violation and has asked a Federal Court to stop Apple distributing the jukebox software.

In a 10-page suit obtained by AppleInsider, the company alleges that Apple's iTunes software infringes on Contois's six-year old design patent entitled "Computer Control System and User Interface for Media Playing Devices."

According to the suit, Apple employees saw Contois' software at trade shows and later copied it.

The company is also claiming monetary damages resulting from Apple's "copying and willful infringement" of its design patent. "By reason of Apple's infringing activities, Contois has suffered, and will continue to suffer, substantial damages in an amount yet to be determined," the suit states.

"On information and belief, Apple's infringement has been and continues to be wilful," claims Contois.
