The subject of today’s topic would probably leave a patent applicant feeling a bit like the reigns are slipping. A patent is not a piece of cake to acquire. The right owner of the invention be it an inventor or an applicant has to prove themselves beyond any doubt. It is the basic right of every individual to oppose the grant of any patent, in cases where such a grant would seem detrimental to a third party. Hence, it would be a justifiable opportunity for third parties to intervene in the procedure of patent grant.
Under the Indian Patent Law, Opposition can be made twice during the life of a patent application. First is the Pre-grant representation under section 25(1) wherein any person may challenge the application for grant of a patent. Pre-grant opposition acts as a defensive shield to confirm the validity of patent applications before patents are granted. Post grant opposition under section 25(2) may be made only by any person interested at any time after the grant of patent but before the expiry of a period of one year from the date of publication of grant of patent.
