I think only humans can create IP, though IANAL.
IANAL either but that's an interesting question. I think machines must be able to generate IP though, otherwise the output of something like Pixar's render farms wouldn't be considered copyrightable, only the source models, animations, textures, shaders etc.
If you are simply using public domain databases as the input, and passing them through an automated process with no creative input, then you probably won't be able to get (or more to the point, enforce) a copyright on it.
Now, whether the databases he's using are copyrighted or not is an interesting question; as well as whether database copyrights even apply. Not all jurisdictions have the notion of database copyrights. Individual facts cannot be copyrighted; but collections of them can, at least in some jurisdictions. However, I don't know if the databases he is using are copyrighted or not.
