Coverage-Disclosure Conundrum and Future of Species Patents in India

Siwal, Ashwini ; Prashant, Prashant


Innovations are mostly derived from already existing technologies that may or may not have been patented. What could one think of, about the patentability of a product, let’s say a pharma product that is made from the group of previously known compounds, some of which are already patented? The answer to this question lies in the very technical field under patent law known as ‘Selection Patents’ or ‘Genus-Species Patents’. Predominantly this concept of selection patent or species patent is seen mostly in the domain of chemical compounds or species, but certainly is not limited to that only, as the same can be applied in other technological areas, such as engineering, biotechnology, material science and telecommunications. Selection patents/inventions are said so as they overlap with the disclosures in the preexisting art. Such aforesaid disclosures generally do not hamper the novelty of the latter invention unless the latter one does not encompass a new embodiment of feature or property. But this isn’t as straight forward as it seems to be. The critical issue in this domain is how to determine the novelty and inventive step of the selection inventions which are entangled in the dichotomy of coverage and disclosure. Off late there have been chunk of cases in India deciphering the coverage-disclosure conundrum in the field of species patents. This paper will foray as to what is this coverage-disclosure conundrum in selection patents, what are the legal framework that are prevalent across other jurisdictions to deal this and what is the future of specie patents in India especially in light of recently filed Dapagliflozin Appeals.
