Oracle will win...
There are three options...
1) SCOTUS ducks the case and the existing verdict stands.
2) SCOTUS hears the case and rules in favor of Oracle.
3) SCOTUS hears the case, rules in favor of Rimini Street, and the case goes back to the court to redo the award to Oracle for damages.
Now these three are not weighted equally. And the odds are that either option 1 or 2 will be higher than option 3. At the same time... if successful, the lower court will re-assess the damages including the legal costs of the appeal(s) and SCOTUS decision.
While the 9th usually gets it wrong, in this case, IMHO, they got it right. In fact Rimini is risking that the original judge could say ... ok, there's willful infringement therefore you face treble the damages plus additional legal fees which would put them back in the same boat.
