If by "implementing a set of APIs," you mean copying them, I would agree,
but isn't that always the case? The more you copy, the stronger the case
of infringement. In fact, that is a conclusion that we might all agree
with. Hence,
copyrightability is still an important part of this equation, but,
perhaps, in a different manner. The distinction is not the question of whether the API,
itself, is
copyrightable, but whether the infringement analysis should
appropriately filter out
uncopyrightable subject matter. In other words, looking at just the
question of infringement, we still need to decide whether an
implementation (or use, or copy) of a set of APIs should require the
filtering (filter prong of the abstraction/filtration test) out of source
code that is not copyrightable. I think the answer is
yes. But, I would also go further than this.
