Judge William Alsup of the U.S. Federal Court for the Northern District of California rejected Psystar's argument that Apple uses anticompetitive practices to prevent companies from selling computers that run Mac OS X, according to court documents spotted by AppleInsider. Psystar can amend its complaint in order to try to convince the judge that it has a better argument, but it has only 20 days to decide whether or not it can overcome the judge's decision.
Psystar has been selling Mac OS-based computers since April, but is under attack in the court system from Apple, which filed a suit against the company in July. Psystar in turn filed its own antitrust complaint against Apple, which some legal observers thought was the company's best chance of winning the dispute and staying in business.
But Alsup was not convinced. He rejected Psystar's argument that the relevant market in this case consisted of a single product: Mac OS. "The pleadings...fail to allege facts plausibly supporting the counterintuitive claim that Apple's operating system is so unique that it suffers no actual or potential competitors," he wrote in his opinion (click here for a PDF copy).
