Re: So the monkey owns the copyright
"And if I record a movie with a camcorder or a concert with my phone, then I own the copyright? Exactly, right this is not the case."
Actually the legal answer is YES, you do in fact on a copyright on that recording. And if the movie-producers or concert-performers start selling copies of your recording then you can sue them into oblivion for violating your copyright. Any court in the 1st world will rule in your favor.
Of course the fact that you own your copyright does not magically cause their copyright to stop existing. If you attempt to start selling copies then they can sue you into oblivion for violating their copyright. Any court on the 1st world will rule in their favor.
There's copyright on the monkey photo, multiple copyrights on your camcorder vid.
There are many common cases where multiple overlapping copyrights exist in this manner. And what it means is that NO ONE can do anything with it, unless they have permission from all applicable copyright holders. Perhaps the most common case is when you buy a CD containing songs from multiple artists. Not only is that CD subject to overlapping copyrights of each performer, the publisher probably has a copyright on the composition of those particular songs in that particular order. No one can manufacture and sell that CD without permission from everyone.
