Abstract

This paper is an empirical study of the effectiveness of patents against imitators based on French survey data. We use a multinomial ordered logit and regress patent effectiveness on qualitative and quantitative variables. We find that patent costs are not a significant limitation on patent effectiveness while patent disclosure is. We also find a positive threshold effect for size. Finally, we observe many differences between the determinants of the effectiveness of product and process patents; in particular, the former is more dependant on R&D intensity and first-mover advantage while the latter is more dependent on market share, advertisement intensity and on the presence of an internal department in charge of intellectual property rights.
