    Abstract

    This paper studies the impact of the strict patent regime on the patenting activity of Indian pharmaceutical firms and finds that patenting activity of these firms has increased after the signing of TRIPs. The study is conducted for 65 pharmaceutical firms for the period 1991 to 2004 using different parametric and semiparametric count panel data models. Results across different count data models indicate a positive and significant impact of the introduction of stronger patents on patenting activity. Further, the results show a gestation lag of 2Â years between R&D spending and patent applications.
