Patents Act, 1970
43. Grant and sealing of patent
(1) Where, a complete specification in pursuance of an
application for a patent has been accepted and either-
(a) the application has not been opposed under
section 25 and the time for the filing of the opposition has expired; or
(b) the application has been opposed and the
opposition has been finally decided in favor of the applicant; or
(c) the application has not been refused by
the Controller by virtue of any power vested in him by this Act, the patent
shall, on request made by the applicant in the prescribed form, be granted to
the applicant or, in the case of a joint application, to the applicants
jointly, and the Controller shall cause the patent to be sealed with the seal
of the patent office and the date on which the patent is sealed shall be
entered in the register.
(2) Subject to the provisions of sub-section (1) and of the
provisions of this Act with respect to patents of addition, a request under
this section for the sealing of a patent shall be made not later than the
expiration of a period of six months from the date of advertisement of the
acceptance of the complete specification:
PROVIDED that-
(a) where at the expiration of the said six months any
proceeding in relation to the application for the patent is pending before the
Controller or the High Court, the request may be made within the prescribed
period after the final determination of that proceeding;
(b) where the applicant or one of the applicants has died before
the expiration of the time within which under the provisions of this
sub-section the request could otherwise be made, the said request may be made
at any time within twelve months after the date of the death or at such later
time as the Controller may allow.
(3) The period within which under sub-section (2) a request for
the sealing of a patent may be made may, from time to time, be extended by the
Controller to such longer period as may be specified in an application made to
him in that behalf, if the application is made and the prescribed fee paid
within that longer period:
PROVIDED that the first-mentioned period shall not be
extended under this sub-section by more than three months in the aggregate.
Explanation : For the purposes of this section a proceeding
shall be deemed to be pending so long as the time for any appeal therein (apart
from any future extension of that time) has not expired, and a proceeding shall
be deemed to be finally determined when the time for any appeal therein (apart
from any such extension) has expired without the appeal being brought.
