Apple is defending iTunes in an ongoing dispute with a David Contois, owner of Contois Music and Technology.

Contois is accusing Apple of stealing his patented software in iTunes. He wants damages, legal expenses and an injunction against the company. He claims he received his patent in 1999.

Apple says it's innocent of the charges levied against it, and has filed a countersuit against Contois that demands its legal expenses be paid.

The two sides met in court yesterday to define the frames of reference for the forthcoming trial. It's a delicate case, the two sides must define the terminology used within media players, and the definitions could favour one or other litigant in the case.
