2009/31: Economic incongruities in the European patent system

This article argues 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 both a high level of uncertainty and an intense managerial complexity which undoubtedly reduces both the effectiveness and the attractiveness of the European patent system in its mission to stimulate innovation.
