Assume a publication agreement between Author (in the US) and Publisher (in the UK, with ample presence in the US), where the rights-granting clause says
Author hereby grants to Publisher the sole and exclusive right and licence to produce and publish and itself further to license the production and publication of the Work or any adaptation or any abridgement of the work in all forms and media and in all languages throughout the world together with the sole and exclusive right to lease to others those volume and specified in clause 11 hereof. Copyright in the Work shall remain the property of the author. The Author hereby asserts his moral rights always to be identified as the author of the Work in accordance to the UK Copyright, Designs and Patents Act 1988
(clause 11 is basically a table of royalties).
Is this effectively different from a transfer of copyright, that is, does Author retain any rights in the work? By granting Publisher the sole and exclusive right to publish, sub-license and create derivative works, in what way does Author retain any right to create a derivative work, or to produce (print and distribute) any such derivative work? Potentially, Author could under UK law (moral rights) stop Publisher from creating an unauthorized modification if Author can prove that the modification is “derogatory”, which is undefined and I assume is judged in terms of whether “a reasonable person” would be offended, rather than a proof that the Author would never have approved such a modification.
The agreement is (per a governing-law clause) subject to the exclusive jurisdiction of English courts, and contains an arbitration clause, which specifies that each party shall name an arbitrator, and there is no provision for a tie-breaker / umpire. For the hypothetical, Author desires to create and distribute a derivative work (perhaps a translation). Can Publisher stop / sue Author for exercising his rights under copyright law? Answers supported by actual case law (US or UK) are most desirable.
