Yes. Google's argument that software APIs weren't copyrightable because of the idea-expression divide didn't find purchase. It won the case on other (fair use grounds). Indeed, if you read the opinion closely, there are a few places where it looks like there used to be a section in the opinion on software API copyrightability (given Breyer was the author, noncopyrightability is probably more apt) that was ripped out in later drafts, presumably because there wasn't the votes for it.
