Judge Dismisses Psystar's Anti-Trust Counterclaim Against Apple

A California judge has dismissed a counterclaim from Psystar which asserted that Apple was violating federal and state anti-trust laws in limiting the sale and use of Mac OS X on Apple branded computers..

But in a 19-page order passed down on Tuesday, Judge William Alsup largely reject Psystar's claims and granted Apple's motion to have the countersuit thrown out of court should the clone maker not better its argument through an amended complaint that can be filed no later than Monday December 8th.

AppleInsider notes that Psystar attempted to define a "Mac OS market" in which Apple held a monopoly. Apple, of course, successfully disputed this definition of a "market" with which the judge agreed.

"Apple asks its customers to purchase Mac OS knowing that it is to be used only with Apple computers," he wrote. "It is certainly entitled to do so."

Psystar is a small company which sells a Mac clone using off-the-shelf PC parts and a modified version of Mac OS X Leopard. Apple sued Psystar over these products and that case is still pending.
