True. However, Oracle could argue that writing good APIs does require money and domain expertise, which could be considered non-obvious and (maybe) copyrightable. For example, look at the Java date/calendar API; it went through a complete revision and still managed to be broken. It's a good question, however, if API designs should be copyrightable in the same fashion building blueprints are.
