This does not match my understanding of the situation (though note: I am not a lawyer; take everything that follows with a grain of salt).
My understanding is that a jury's primary task of deciding on the facts is final. The facts in a case like this seem to me to be things like deciding whether Oracle in fact holds the copyright, and whether Google's copy of the API is sufficiently similar for that copyright to apply to Google's copy.
Now as far as appeals go, you can appeal whether the trial was done properly, such that the jury was able to do its fact-finding job correctly. You can appeal what was then decided based on those facts (e.g. sentencing). You can appeal meta-questions, like whether a particular decision is a "finding of fact" or not to start with.
The question of whether "fair use" is the sort of thing that is decided by judge or jury is apparently somewhat contentious in this case; I just found https://www.law.uw.edu/wlr/print-edition/print-edition/vol-9... describing some of the issues there. Today's decision refers to this as well: it's (c) under "Held":
> (c) The fair use question is a mixed question of fact and law. Re- viewing courts should appropriately defer to the jury’s findings of un- derlying facts, but the ultimate question whether those facts amount to a fair use is a legal question for judges to decide de novo. This ap- proach does not violate the Seventh Amendment’s prohibition on courts reexamining facts tried by a jury, because the ultimate question here is one of law, not fact. The “right of trial by jury” does not include the right to have a jury resolve a fair use defense. Pp. 18–21.
which sure sounds like the Supreme Court effectively decided that the final determination of whether a use is "fair use" or not should be made by a judge, not a jury. Then they proceed to make that determination in this case in holding (d).
