Generally, the Supreme Court finds narrowly on a specific point of friction in the case of a lesser court, answers the question, and kicks it back to that court, as a final answer for that very specific thing. The point in this case was, can Oracle overturn the "phone books cannot be Copyrighted" concept baked into tech law by the IBM v Compaq BIOS case. Seems the Supreme Court finally told Oracle the collection of method signatures from the Java base API are, indeed, a phone book.
