While often presumed in academic literature and policy discussions there is little empirical evidence showing that academic patents protect more basic inventions than corporate patents. This study provides new evidence on the basicness of academic patents using German professor patents linked to patent opposition data from the European Patent Office (EPO). Patent oppositions are the most important mechanism by which the validity of patents filed at the EPO can be challenged. Controlling for patent value, asymmetric information and diverging expectations between the opposition parties, the likelihood of a potentially litigious situation and the relative costs of opposition versus settlement, we find that academic patents are opposed less frequently than a control group of corporate patents. This suggests that academic patents cover rather basic inventions with a low immediate commercial value not threatening current returns of potential plaintiffs. The effect is weaker for academic patents in collaboration with the business sector, which suggests that those patents are evaluated as more applied by owners of potentially rival technologies.
Patent pendencies create uncertainty in research and development (R&D) collaboration agreements, resulting in a threat of expropriation of unprotected knowledge by potential partners, reduced bargaining power and enhanced search costs. In this paper, we show that - depending of the type of partner - uncertain intellectual property rights (IPR) lead to reduced collaboration between firms and may hinder the production of knowledge. This has implications for technology policy as R&D collaborations are exempt from anti-trust legislation in order to increase R&D in the economy. We argue that a functional IPR system is needed for successful utilization of this policy.

SUMMARYWhile often presumed in academic literature and policy discussions there is little empirical evidence showing that academic patents protect more basic inventions than corporate patents. This study provides new evidence on the basicness of academic patents using German professor patents linked to patent opposition data from the European Patent Office (EPO). Patent oppositions are the most important mechanism by which the validity of patents filed at the EPO can be challenged. Controlling for patent value, asymmetric information and diverging expectations between the opposition parties, the likelihood of a potentially litigious situation and the relative costs of opposition versus settlement, we find that academic patents are opposed less frequently than a control group of corporate patents. This suggests that academic patents cover rather basic inventions with a low immediate commercial value not threatening current returns of potential plaintiffs. The effect is weaker for academic patents filed in collaboration with the business sector, which suggests that those patents are evaluated as more applied by owners of potentially rival technologies.
Against the background of the so-called European paradox, i.e. the conjecture that EU countries lack the capability to transfer science into commercial innovations, knowledge transfer from academia to industry has been a central issue in policy debates recently. Based on a sample of German scientists we investigate which academic inventions are patented by a scientific assignee and which are owned by corporate entities. Our findings suggest that faculty patents assigned to corporations exhibit a higher short-term value in terms of forward citations and a higher potential to block property rights of competitors. Faculty patents assigned to academic inventors or to public research institutions, in contrast, are more complex, more basic and have stronger links to science. These results may suggest that European firms lack the absorptive capacity to identify and exploit academic inventions that are further away from market applications.
