In the ongoing litigation between Psystar and Apple, the Mac clone maker has made a controversial claim that Apple improperly registered the copyright to OS X and thus their infringement claims against them are invalid. Should the new claim hold up in court it would mean big trouble for Apple but, of course, the mere notion that one of the most protective companies in the industry just didn't take the time to properly register the copyright to its flagship product is rather absurd.

Psystar may well have realized it’s fighting a losing battle and is delaying their inevitable demise under the weight of Apple’s lawyers. This follows a counterclaim suit against Apple being thrown out of court last month and a subsequent change in tactic to focus on copyright abuse. The amended claim also reiterates earlier concerns that Apple is using a startup check in Mac OS X Leopard to block unauthorized systems from running the software.
