(1) Notwithstanding anything contained in the other provisions of this chapter, at any time after the sealing of a patent, any person who has the right to work any other patented invention either as patentee or as licensee thereof, exclusive or otherwise, may apply to the Controller for the grant of a license of the first-mentioned patent on the ground that he is prevented or hindered without such license from working the other invention efficiently or to the best advantage possible.
(2) No order under sub-section (1) shall be made unless the Controller is satisfied-

(ii) that the other invention has made a substantial contribution to the establishment or development of commercial or industrial activities in India.
(3) When the Controller is satisfied that the conditions mentioned in sub-section (1) have been established by the applicant, he may make an order on such terms as he thinks fit granting a license under the first-mentioned patent and a similar order under the other patent if so requested by the proprietor of the first-mentioned patent or his licensee.
(4) The provisions of sections 92 and 110 shall apply to licenses granted under this section as they apply to licenses granted under section 84.
