They've got post-verdict motions at the trial court, if that fails they can speak to the Circuit Court (I think this will go to the Ninth Circuit now rather than the Federal Circuit, but that may be incorrect.) If they fail their, they can petition to have the Supreme Court take up the case (their refusal to take up a different question in an interlocutory -- prior to final judgement -- appeal previously shouldn't be considered a strong signal of whether they would take the same or a different question on appeal of a final judgement.)

At the Circuit and Supreme Court level, expect Google to cross-appeal against the copyrightability issue again (the Ninth Circuit might well rule differently than the CAFC did applying -- in theory -- Ninth Circuit precedent, and in any case I think they'll need to do so at the Circuit level to keep the issue alive for the Supreme Court, which may week take the issue up on a final speak though it declined to do so on an interlocutory one.)
