Not a lawyer, and I agree with your overall point, but I think usage examples are as tainted as the raw API.If the API is copyrighted with no fair use exemption for interop, why would that protection not extend to the API usage which contain the same information? "void IFoo.bar()" and "myFoo.bar() // returns void" are pretty similar and equally as "infringing" IMO.

These $9 Billion dollars will look great on Oracles bottom line. The mega-billions in possible lost trade and efficiency make me think this ruling gets reversed with a vengeance.
