Previously in the Apple-Psystar legal battle, the clone maker amended its countersuit to charge that Apple was unfairly leveraging its copyright by binding Mac OS X to Mac hardware.
On Friday, the federal judge assigned to the case ruled that the amendment will be heard by the court, a small victory for Psystar. It's something of a reversal for the company, since they had federal antitrust allegations thrown out in November. Similarly, Psystar's assertion that Apple is in violation of California's antitrust laws was thrown out Friday as well.
Judge William Alsup said, "Psystar may well have a legitimate interest in establishing misuse [of copyright] independent of Apple's claims against it -- for example, to clarify the risks it confronts by marketing the products at issue in this case or others it may wish to develop." This isn't to say that the judge necessarily agrees with Psystar's point, but just that it's legally reasonable enough to be argued in court.
Apple has also not yet revealed its 10 "John Doe" defendants: alleged conspirators who worked on Psystar's technique for loading Mac OS X on non-Apple hardware.
The case will decide whether or not Apple can disallow other hardware makers -- including Psystar -- from including Mac OS X on computers shipped to end users. Last week, a company in Germany claimed that Mac OS X's End User License Agreement didn't apply to them, and is selling Mac clones to customers.
The case is scheduled to go to trial on November 9.
