Assignment of copyrights.

Section 18 of the Copyright Act deals with the assignment of copyrights. It provides that: The owner of the copyright in an existing work or the prospective owner of the copyright in a future work may assign to any person the copyright either wholly or partially and either generally or subject to limitations and either for the whole term of the copyright or any part thereof; Provided that in the case of the assignment of copyright in any future work, the assignment shall take effect only when the work comes into existence. Where the assignee of a copyright becomes entitled to any right comprised in the copyright, the assignee as respects the rights so assigned, and the assignor as respects the rights not assigned, shall be treated for the purposes of this Act as the owner of copyright and the provisions of this Act shall have effect accordingly. 'No assignment of the copyright in any work shall be valid unless it is in writing signed by the assignor or by his duly authorized agent.'
