No, it could still be appealed. But if the appeal is dismissed, that's likely that. The US has three levels of Federal courts for this sort of matter. Right now they're in the lowest level, the district court. If this case's eventual disposition is appealed, it goes to the appellate court, who would determine if the law was correctly applied. Judge Zilly is very well-regarded in his understanding of US law and is unlikely to make any errors, so any appeal seems futile. But, if someone wanted to keep fighting, the case could be elevated to the Supreme Court...who won't bother with it. As I said before, outside of the gaming and anime markets, the case is neither particularly notable nor important.
