Actually its UK law that this descends from and it is only "related" works. If you where a semi pro musician google would not own the rights to your song's for example.

And it not copyright they "own" it - I suspect the tweeter is confused between intellectual property and copyright

Germany has this http://www.mondaq.com/germany/x/645260/Patent/Artificial+Int...) which is similar its probably EU countries relay on statutory law and don't explicity put it into the contract so you would never know
