But we are talking about copyright, not patents. So to stretch your analogy. Imagine I'm a door manufacturer, or maybe a manufacturer of tools for construction so that professionals can make their own doors. I create some kind of stencil that has the doorknob placement cut-out. And maybe a few variants with places for windows and such. The general idea of such a stencil might be patentable, even if the general standard dimensions are not. The tool is a unique idea (maybe). But we are talking about copywritten material. The specific stencil design, that you could photocopy is the thing in question. And that is one of several arguments Oracle made, that api interface is a stencil. I think I would agree the law supports that argument from what I know about it, copyright is pretty broad. But at the same time, I think that is perverse and we should change the law.
