"In order to declare a particular functionality, the language demands that the method declaration take a particular form," notes Alsup (emphasis in original).
Indeed, this is just so. And you can't copyright "functionality"; that's akin to copyrighting a concept, which is not what copyright is about. Copyright is about protecting implementations of concepts, and those are still protected. But a programming language requires a rigid codification of the concept itself.
Oracle's response made me chuckle a little...
"The court's reliance on "interoperability" ignores the undisputed fact that Google deliberately eliminated interoperability between Android and all other Java platforms," the company said in a statement issued this afternoon. "Google's implementation intentionally fragmented Java and broke the "write once, run anywhere" promise."
That's really immaterial to the reasoning for why an APIs aren't protected under the Copyright Act in the first place. It would be relevant if "interoperability" were a defense against copyright infringement, but it's not, since the item in question wasn't protected in the first place.
Just because my implementation of fopen() breaks programs that depended on your implementation of fopen() that doesn't suddenly mean that your declaration of a function called fopen() is protected and my identical declaration is infringing. This would imply that copyright infringement claims based on APIs would suddenly be dependent on some kind of compatibility test.
And on that note, it was that last line that made me chuckle. Brings to mind something about ships and sailing, or barn doors and horses.
