Yeah, "essentially" is another one of those weasel words.
Operating from
the groklaw version, there are five questions of summary judgement that the judge ruled on.
1. Summary judgement is for when there are no facts at dispute. When facts remain in dispute, trial continues.
2A. Psystar copying something they don't hold the copyright on is a clear copyright violation, though it does appear that Psystar already waived a defense that they're trying to raise here.
2B. Psystar made changes to OS X and distributed a version of OS X with those changes. That's a derivative work, and they have no right to distribute it. It doesn't matter if they also distributed a non-modified version. (Apple does not appear to have been claiming that distributing the non-modified version was a violation.) EULA is not a factor here--this is basic copyright law.
2C. Yes, swapping out portions of the code, even if the individual files aren't changed, is creating a derivative work of the OS.
2, full summary: Making a derivative work, copying it, and then distributing the copy, is a copyright violation. Oh, and selling a copyright violation so that someone else can use it is also contributory infringement. This is basic copyright law, and has nothing to do with a EULA. No facts in dispute, Apple wins a summary judgement.
3. This is the only one that could hinge on a EULA turning a purchase into a license. However, all it does is not grant Psystar summary judgement. Summary judgement simply means that the facts are so obvious that the there is no need for further trial. Apple has been granted summary judgement on 1, 2, and 4. Psystar was not granted summary judgement on 3: the facts are still in dispute.
4. DMCA. Yes, breaking a key to make software work the way you want it to, violates the DMCA. The DMCA sucks, but it is the law.
5. Psystar's claim that their use of Apple's trademark was legal was not granted summary judgement, apparently because Psystar's lawyers provided no legal citations. If Psystar wants to continue this argument, they'll have to continue it in court. And maybe do some actual work this time.
6. Psystar apparently asked the court to restrict injunctions and damages that Apple didn't even ask for, and so the court bails on making any decision.
For all the conspiracy theories I've been hearing, it sounds like Psystar has some crappy lawyers. You don't generally waive defenses that you plan on bringing later...
