When Psystar had charges brought on by Apple, for their Mac OS X clones they didn’t stand idly by. Psystar instead took proactive steps to fight back, even if their fight was a moot point.
Psystar’s claim against Apple, is that they are violating anti-trust laws by only allowing Mac OS X on Apple products. According to Psystar, this warranted an investigation for Apple to have a monopoly.
It was a relatively fast decision, as the judge has already dismissed the case. Apple is fairing better with their claim against Psystar, as it’s still pending.
