(1) A contract in which the author grants rights in respect of unknown types of use, or in which the author undertakes to do so, must be drawn up in writing. There is no need for a written contract in cases where the author grants to all an unremunerated non-exclusive right of use. Where the author concludes a contract as defined in sentence 1 with a collecting society, text form suffices. The author may revoke this grant of a right or revoke the obligation thereto. The right of revocation expires after three months have elapsed since the other person sent the author, at the address last known to the sender, notification of the intended commencement of the new type of use of the author’s work.
(2) The right of revocation does not apply where the parties, upon becoming aware of the new type of use, have agreed on remuneration in accordance with section 32c (1). The right of revocation also does not apply where the parties have arranged for remuneration under a joint remuneration agreement. The right of revocation expires upon the author’s death.
(3) If there is consolidation of more than one work, or more than one contribution to a work, into one entity which, in the new type of use, may be used appropriately only in circumstances where there is exploitation of all works or contributions to a work, the author may not exercise the right of revocation contrary to good faith.
(4) There can be no advance waiver of the rights under subsections (1) to (3).
