@abmurrow @blogdiva (I'm not a lawyer, but) SCOTUS is primarily an appellate court, they take 99% of cases on appeal, at their discretion. Declining to take the cases means that the lower (circuit) courts' rulings stand, and remain as binding precedent in those circuits. There's multiple reasons not to take an appeal and to my knowledge they don't publish explanations for declining to take appeals, but probably they either think the lower court is very likely right, and/or they think it's just not important enough to give it some of the limited space on their docket.
Technically no court case is *truly* final as sufficiently motivated lawyers and judges can get even decades-old settled precedent overturned, but it's not likely to here unless Congress passes a significantly reworked copyright act as the current statute seems pretty clear about the whole "human creativity" thing (demonstrated by several courts agreeing) even if the language is a little more legalistic than that.
