There's an interesting post on Sulliman's site on the subsistence of copyright in computer generated works "Les creations assistees par ordinateur sont elles protegeables?" He discusses some recent French case law and academic discussion, particularly on whether computer generated works are original.
In Express Newspapers plc v Liverpool Daily Post & Echo  FSR 306, an application for an interim injunction wherapplicantlicant had to satisfy the judge that it could win, the applications judge saw no difficulty in the work in question being computer generated. He regarded the computer as a tool in much the same way as a pen is a tool. He regarded the argument that the computer was the author as "as unrealistic as it would be to suggest that, if you write with a pen, it is the pen that is the author of the work rather than the person who drives the pen."
Shortly afterwards, Parliament provided in s.9 (3) of the Copyright Designs and Patents Act 1988:
"In the case of a literary, dramatic, musical or artistic work which is computer-generated, the author shall be taken to be the person by whom the arrangements necessary for the creation of the work are undertaken."
I am surprised there has not been an Express Newspapers case before the French courts before now.
