Patents Act, 1970
93. Powers of Controller in granting compulsory licenses
(1) Where the Controller is satisfied on application made under
section 84 that the manufacture, use or sale of materials not protected by the
patent is prejudiced by reason of conditions imposed by the patentee upon the
grant of licenses under the patent, or upon the purchase, hire or use of the
patented article or process, he may, subject to the provisions of that section,
order the grant of licenses under the patent to such customers of the applicant
as he thinks fit as well as to the applicant.
(2) Where an application under section 84 is made by a person
being the holder of a license under the patent, the Controller may, if he makes
an order for the grant of a license to the applicant, order the existing
license to be cancelled, or may, if he thinks fit, instead of making an order
for the grant of a license to the applicant, order the existing license to be
amended.
(3) Where on an application made under section 84, the
Controller orders the grant of a license, he may, for reasons to be recorded in
writing, direct that the license shall operate-
(a) to deprive the patentee of any right which
he may have as patentee to make, use, exercise or vend the invention or to
grant licenses under the patent;
(b) to revoke all existing licenses in respect
of the invention.
(4) Where two or more patents are held by the same patentee and
an applicant for a compulsory license establishes that the reasonable
requirements of the public have not been satisfied with respect to some only of
the said patents, then, if the Controller is satisfied that the applicant
cannot efficiently or satisfactorily work the license granted to him under
those patents without infringing the other patents held by the patentee, he
may, by order, direct the grant of a license in respect of the other patents also
to enable the licensee to work the patent or patents in regard to which a
license is granted under section 84.
(5) Where the terms and conditions of a license have been
settled by the Controller, the licensee may, at any time after he has worked
the invention on a commercial scale for a period of not less than twelve
months, make an application to the Controller for the revision of the terms and
conditions on the ground that the terms and conditions settled have proved to
be more onerous than originally expected and that in consequence thereof the
licensee is unable to work the invention except at a loss:
PROVIDED that no such application shall be entertained
a second time.
