Among the most prominent theoretical frameworks dealing with the economic underlyings of firms' make-or-buy decisions are Transaction Cost Economics (TCE) and the Resourced Based View (RBV). Relying on panel data covering 107 European firms over eight years I test predictions from both TCE and...

There has been a wide-spread misconception based on the imprecise wording of Art. 52 of the European Patent Convention (EPC) that the protection of business methods by patents is prohibited in Europe. This paper investigates the legal framework set by patent laws with respect to the...

Microsoft hat eine marktbeherrschende Stellung im Software-Markt, konkurriert aber mit einer Vielzahl von Wettbewerbern im benachbarten Markt für Cloud-Computing. Inwiefern führt die von Microsoft praktizierte Verknüpfung von Software-Produkten mit Cloud-Computing-Dienstleistungen zu...

We analyze the duration of the patent examination process at the EuropeanPatent Office (EPO). Our data contain information related to the patent’seconomic and technical relevance, EPO capacity and workload as well as novelcitation measures which are derived from the EPO’s search reports. In...

Most econometric analyses of patent data rely on regression methods using a parametric form of the predictor for modeling the dependence of the response given certain covariates. These methods often lack the capability of identifying non-linear relationships between dependent and independent...

We investigate incidence and evolution of patent thickets. Our empirical analysis is based on a theoretical model of patenting in complex and discrete technologies. The model captures how competition for patent portfolios and complementarity of patents affect patenting incentives. We show that...
