Eddie Cue, vice president of iTunes at Apple Computer, took the witness stand Monday to defend his company in the trademark lawsuit brought on by The Beatles’ Apple Corps. Cue testified that Apple Computer did not violate a 1991 agreement between the two companies by using the Apple logo on the iTunes Music Store. Apple Corps lawyer Geoffrey Vos asked Cue to confirm that the iTunes Music Store had offered exclusive songs from artists such as U2 and Bob Dylan. “We have tracks that are temporarily exclusive to us in the Music Store, and so do most of the other services,” Cue said in the High Court in London. James Hoffman, CEO of Woodstock Systems, testified earlier on behalf of Apple Corps that Apple Computer converts its music files into a proprietary format to restrict how they are used.
