Namrata Chadha, of K&S Partners, a Tier 1 Indian law firm, discusses various crucial aspects relating to patenting of selection inventions in India, especially in pharmaceuticals and chemicals. Summary: The patenting of selection inventions is not plain sailing in India. The patentability of such inventions must be determined in accordance with the general provisions of the Indian Patents Act, as there is no separate provision for the same in the Act. Of the said general provisions, the assessment of inventive step and testing under section 3(d) of the Indian Patents Act can be perceived as the most critical to patentability of selected novel species. Additionally, the concepts of ‘implicit disclosure’ and the contrasting views on ‘coverage vs disclosure’ frequently makes it challenging for applicants to defend their novel selection under the Indian scenario. Given the lack of enough precedents in India on this aspect, to date the fate of selection patents depends mostly on the judgement of the patent controllers. Not all hope is lost, however, since not only the Indian Patent Office, but also the IPAB and higher Courts have time-and-again acknowledged the existence of selection patents in India.
