Patents Act, 1970
28. Mention of inventor as such in patent
(1) If t he controller is satisfied, upon a request or claim
made in accordance with the provisions of this section-
(a) that the person in respect of or by whom
the request or claim is made is the inventor of an invention in respect of
which application for a patent has been made, or of a substantial part of that
invention; and
(b) that the application for the patent is a
direct consequence of his being the inventor, the Controller shall, subject to
the provisions of this section, cause him to be mentioned as inventor in any
patent granted in pursuance of the application in the complete specification
and in the register of patents:
PROVIDED that the mention of any person as inventor
under this section shall not confer or derogate from any rights under the
patent.
(2) A request that any person shall be mentioned as aforesaid
may be made in the prescribed manner by the applicant for the patent or (where
the person alleged to be the inventor is not the applicant or one of the applicants)
by the applicant and that person.
(3) If any person [other than a person in respect of whom a
request in relation to the application in question has been made under
sub-section (2),] desires to be mentioned as aforesaid, he may make a claim in
the prescribed manner in that behalf.
(4) A request or claim under the foregoing provisions of this
section shall be made not later than two months after the date of advertisement
of acceptance of the complete specification or within such further period (not
exceeding one month) as the Controller may, on an application made to him in
that behalf before the expiration of the said period of two months and subject
to the payment of the prescribed fee, allow.
(5) No request or claim under the foregoing provisions of this
section shall be entertained if it appears to the Controller that the request
or claim is based upon facts which, if proved in the case of an opposition
under the provisions of clause (a) of sub-section (1) of section 25 by the
person in respect of or by whom the request or claim is made, would have
entitled him to relief under that section.
(6) Subject to the provisions of sub-section (5), where a claim
is made under sub-section (3), the Controller shall give notice of the claim to
every applicant for the patent (not being the claimant) and to any other person
whom the Controller may consider to be interested; and before deciding upon any
request or claim made under sub-section (2) or sub-section (3), the Controller
shall, if required, hear the person in respect of or by whom the request or
claim is made, and, in the case of a claim under sub-section (3), any person to
whom notice of the claim has been given as aforesaid.
(7) Where any person has been mentioned as inventor in pursuance
of this section, any other person who alleges that he ought not to have been so
mentioned may at any time apply to the Controller for a certificate to that
effect, and the Controller may, after hearing, if required, any person whom he
may consider to be interested, issue such a certificate, and if he does so, he
shall rectify the specification and the register accordingly.
