If a literary work’s copyright belongs to the human being who created it, then the copyright should last for the writer’s lifetime plus ten years — twenty if he has minor children at the time of his death.
But if the copyright is owned by a corporation or company, then the copyright should last fifteen years. Period. Done. After that, anybody can duplicate the copyrighted work without paying anything.
