Copyright law has long recognized in authors an unwaivable right to terminate certain contracts and licensing agreements. A handful of high-profile cases have already called substantial attention to this termination provision, with disputes touching such iconic characters as Superman, Captain America, the Fantastic Four, Lassie, and Winnie the Pooh. In this edition of the IP Colloquium, copyright guru David Nimmer joins UC Berkeley Professor Peter Menell and UCLA Professor Doug Lichtman in an informal conversation about the termination right, its controversies, and the implications for modern copyright practice.
