  One of the big open questions is "are APIs copyrightable?" 

The Australian equivalent to the US Supreme Court considered this over 20 years ago, and imho got the correct result (not copyrightable): http://www.austlii.edu.au/cgi-bin/viewdoc/au/cases/cth/HCA/1...

IMHO they got the Huffman table wrong, although arguably it was the result compelled by an overprotective approach.
