Rule 84
84. Restoration of patents.—
(1) An application for the restoration of a patent under section 60 shall be made in Form 15.
(2) Where the Controller is satisfied that a prima facie case for the restoration of any patent has not been made out, he shall intimate the applicant accordingly and unless the applicant makes a request to be heard in the matter within one month from the date of such intimation, the Controller shall refuse the application.
(3) Where the applicant requests for a hearing within the time allowed and the Controller, after giving the applicant such a hearing, is prima facie satisfied that the failure to pay the renewal fees was unintentional, he shall publish the application.
