Section 84 of the Patents Act, 1970 allows any interested person — including an existing licensee under the patent — to apply to the Controller for a compulsory licence once three years have elapsed from the date of grant, provided statutory grounds are made out.

The Statutory Framework

An application for compulsory licence under Section 84 may be made on one or more of the following grounds: that the reasonable requirements of the public with respect to the patented invention have not been satisfied; that the patented invention is not available to the public at a reasonably affordable price; or that the patented invention is not being worked in the territory of India.

Who May Apply

Notably, the provision is not limited to third parties with no connection to the patent — even an existing licensee under the patent may apply for a compulsory licence if it considers the terms of its existing licence do not satisfy the statutory grounds.

Broader Policy Context

Compulsory licensing sits within a broader public-interest framework in Indian patent law, particularly for pharmaceuticals. This is reinforced by parallel regulatory efforts — including government initiatives aimed at preventing generic manufacturers from obtaining marketing approval to sell patented drugs in India without authorisation — reflecting the tension Indian policy continually navigates between incentivising patented innovation and ensuring public access to essential goods, especially medicines.
