The various creative commons licenses and various copy-left and similar licenses all claim to be "perpetual" or "irrevocable" -- to last for the term of the copyright. For example, the CC-BY 4.0 license says:
Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material
The other CC license include a similar provision.
But 17 USC 203 says:
In the case of any work other than a work made for hire, the exclusive or nonexclusive grant of a transfer or license of copyright or of any right under a copyright, executed by the author on or after January 1, 1978, otherwise than by will, is subject to termination under the following conditions
(3) Termination of the grant may be effected at any time during a period of five years beginning at the end of thirty-five years from the date of execution of the grant; or, if the grant covers the right of publication of the work, the period begins at the end of thirty-five years from the date of publication of the work under the grant or at the end of forty years from the date of execution of the grant, whichever term ends earlier.
(4) The termination shall be effected by serving an advance notice in writing, signed by the number and proportion of owners of termination interests required under clauses (1) and (2) of this subsection, or by their duly authorized agents, upon the grantee or the grantee’s successor in title.
This document from the US Copyright office describes the law and the process under it. So does this article from WIPO magazine. This short article from a law office summarizes the provisions of Sections 203 and 304 of Title 17 (the US Copyright Law). This article from the Author's Guild summerizes the law from the POV of a literary author.
Given this provision, how can such licenses for US works plausibly claim to be "irrevocable"? Cannot the author or rights-holder terminate any such license after 35 years under this procedure?
