Resumen de Economic incongruities in the European patent system

Malwina Mejer, Bruno van Pottelsberghe de la Potterie

• This article suggests that the consequences of the ‘fragmentation’ of the European patent system are more dramatic than the mere prohibitive costs of maintaining a patent in force in many jurisdictions. The prevalence of national jurisdictions, which are highly heterogeneous in their costs and practices, over the validity and enforcement of European patents, induces a high level of uncertainty and an intense managerial complexity which reduce both the effectiveness and the attractiveness of the European patent system in its mission to stimulate innovation.
