To the chagrin of many authors, copyright usage contracts are usually concluded "forever"; the creator can only terminate and reassign the work rights in exceptional cases. The US Copyright Act offers a remedy here with the inalienable "Termination Right" 35 years after the conclusion of the contract, which was almost introduced into German copyright law in 2002. This book comprehensively presents the development and functioning of this American legal institute, which also affects German authors and users, examines the German and other foreign legal situation on the ordinary termination of usage contracts and, based on this, develops a draft for the German copyright law.
