Consider Victor Hugo's novel Les Mis&eacute;rables. Since he wrote it, the copyright belonged only to him. He did not have to fear that some stranger could sue him for copyright infringement and win. That was impossible, because copyright covers only the details of a work of authorship, not the ideas embodied in them, and it only restricts copying. Hugo had not copied Les Mis&eacute;rables, so he was not in danger from copyright.
