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.20 p.application/pdfengcc-by-nc-nd, (c) Mejer et al., 2009http://creativecommons.org/licenses/by-nc-nd/3.0/es/Llicències de patents d'invencióProcessosJurisdiccióPatent licensesTrialsJurisdictioninfo:eu-repo/semantics/workingPaperinfo:eu-repo/semantics/openAccess
