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.
