I also don't think the fact that APIs aren't copyrightable is a clear cut case.
Can you imagine if int add( int, int ) were (or suddenly became) copyrightable?
Perhaps that can be seen as too trivial; but consider something like:
If, every time a programmer sat down to write a function; he had to perform a copyright search to check that he wasn't duplicating a function signature that someone else had used somewhere at some time in the past, this industry would grind to a complete halt.
That is proof by reductio ad absurdum, but the principle holds. And with the advent of IP Trolls, and the general rise and rise of companies like Apple and Oracle using litigation as the first resort rather than the last; it is not so absurd.
Api definitions involve little more than the serial juxtaposition of a half a dozen or so keywords, chosen from a very limited subset. The permutations are finite.
Imagine if writers were able to copyright phrases -- short combinations of common words. It would very soon lead to the situation where it became impossible to communicate in writing at all.
