(1) If an assignee fails to make sufficient exercise of the rights assigned to him, and such failure is not attributable to any act or omission of the assignor, then, the Copyright Board may, on receipt of a complaint from the assignor and after holding such inquiry as it may deem necessary, revoke such assignment.
(2) If any dispute arises with respect to the assignment of any copyright the Copyright Board may, on receipt of a complaint from the aggrieved party and after holding such inquiry as it considers necessary, pass such order as it may deem fit including an order for the recovery of any royalty payable:
Provided that the Copyright Board shall not pass any order under this sub-section to revoke the assignment unless it is satisfied that the terms of an assignment are harsh to the assignor in case the assignor is also the author:
Provided further that, pending the disposal of an application for revocation of assignment under this subsection, the Copyright Board may pass such order, as it deems fit regarding the implementation of the terms and conditions of assignment including any consideration to be paid for the enjoyment of the right assigned.
Provided also that no order of revocation of assignment under this subsection, be made within a period of five years from the date of such assignment.
(3) Every complaint received under sub-section (2) shall be dealt with by the Copyright Board as far as possible and efforts shall be made to pass the final order in the matter within a period of six months from the date of receipt of the complaint and any delay in compliance of the same, the Copyright Board shall record the reasons thereof.
