Good question. I suspect you'll have to go to court and get a ruling after fighting it out. The "Monkey Selfie" case seemed like a giant waste of time, as animals can't own copyrights, but that went to court.

I have an "AutoMondrian" program that creates "art", and I'm not sure what the copyright status of the "art" is.

I think this grey area demonstrates that "Intellectual Property" is pretty much a false concept.
