Patent Disclosure and R&D Competition in Pharmaceuticals.

By Laura Magazzini, Fabio Pammolli, Massimo Riccaboni and Maria Alessandra Rossi


The prominent role played by patents within the pharmaceutical domain is unquestionable. In this paper we take an unusual perspective and focus on a relatively neglected implication of patents: the effect of patent-induced information disclosure (of both successes and failures) on the dynamics of R&D and market competition. The study builds upon the combination of two large datasets, linking the information about patents to firm level data on R&D projects and their outcome. Two case studies in the fields of anti-inflammatory compounds and cancer research complement our analysis. We show the important role played by patent disclosure in shaping firms technological trajectories through the possibility of reciprocal monitoring in a context of parallel research efforts, and suggest the importance of enhancing the diffusion of information concerning failures, not only to avoid wasteful duplication of innovative efforts, but also as a tool for the identification of promising research trajectories. This paper is the result of the "R&D competition" research project carried out jointly with Adrian Towse and Martina Garau of the Office of Health Economics, London, UK. A preliminary draft of the paper has been presented to the DRUID Summer Conference 2006 (Copenhagen), and to the 11th ISS Conference (Sophia-Antipolis).patent disclosure; innovation; r&d competition
