Hmm. Can an art gallery copyright the organization of art on their wall? What if it increases their revenue, and is an inherently creative act?
If someone bought a bunch of prints of the same art, tacked it to some dry wall in the same layout and sold it at a flea market -- would it be copyright infringement? If they blatantly copy the name of the gallery as well, I'd argue it as trademark infringement -- not copyright infringement. But again, this is the UK. I'm only lay-familiar with US copyright.
Some would argue the Java API took an immense amount of creativity to build. Doesn't mean it's copyrightable.
Some would argue that a cake is a cake is a cake, others that it takes a great amount of creativity to create a truly amazing cake recipe. Still doesn't mean you can copyright a recipe.
Just because creativity is involved doesn't make something inherently copyrightable.
