SURRENDER AND REVOCATION OF PATENTS :
Section 63 entitles the patentee to offer to surrender his patent, at any time by giving notice to the Controller. Where such an offer is made, the Controller shall publish the offer in the prescribed manner and also notify every person other than the patentee whose name appears in the register as having an interest in the patent. Any person interested may, within the prescribed period after such publication, give notice of opposition to the Controller and where such notice in given the Controller shall notify the patentee. If the Controller is satisfied after hearing the patentee and any opponent, if desirous of being heard, that the patent may properly be surrendered, he may accept the offer and by order revoke the patent.
