In this paper we examine the implications of uncertainty over patent validity on patentholders' licensing strategies. Two licensing mechanisms are examined: per-unit royalty and up-front fee.We provide conditions under which uncertain patents are licensed in order to avoid patent litigation. It...

In this paper, we revisit the issue of licensing ‘weak' patents under the shadow of litigation. Departing from the seminal paper by Farrell and Shapiro [2008], we consider innovations of any size and not only ‘small' innovations, and we allow the number of licensees to be less than the...

L'article analyse les complémentarités et les tensions entre la concurrence et l'innovation tant du point de vue des instruments d'analyse que du point de vue des politiques économiques.

This paper investigates the choice of an intellectual protection regime for a process innovation. We set up a multi-stage model in which choosing between patent and trade secrecy is affected by three parameters : the patent strength defined as the probability that the right is upheld by the...

The paper examines under what conditions vertically differentiated duopolists engage in first-degree price discrimination. Each firm decides on a pricing regime at a first stage and sets prices at a second stage. The paper shows that when unit cost is an increasing and convex function of...
