Technological standards give rise to a complements problem that affects pricing and innovation incentives of technology producers. In this paper I discuss how patent pools can be used to solve these problems and what incentives patent holders have to form a patent pool. I offer some suggestions...

The traditional argument that shorter product cycles favor trade secret over patenting is reviewed. A game theoretic model provides an argument that shorter product cycles can induce firms to file more patent applications. The firms may be trapped in a prisoners' dilemma where all firms would...

Using firm level panel data from the U.S., I explore the relationship between firm size and R&D productivity for two important and R&D-intensive industries: Semiconductors and Pharmaceuticals. I employ two measures of a firm's R&D performance: the number of citations received per patented...

Die Analyse der Patentanmeldungen deutscher Unternehmen am Europäischen Patentamt zeigt: Die Unternehmen lenken ihre Forschungsaktivitäten im Ausland vor allem in die Hochtechnologiebereiche, in denen sie seit langem besonders intensiv forschen. Dies sind die Elektrotechnik, Steuerungstechnik,...

This paper examines the effect of the German co-determination law of 1976 (MitbestG) on the innovative activity of German firms. Co-determination applies to firms with 2000 employees or more. Data from 1971-1976 and 1981-1990 on 148 firms are used to compare the number of patents granted to...

Die Rolle von Normen innerhalb des Innovationssystems ist sehr umstritten. Es wird sogar vermutet, dass die Zeit der Normung bereits abgelaufen sei. Andererseits wird von einer erstarrenden Regelsetzung gesprochen, die die notwendige Flexibilität für Erfindungen und Innovationen verhindere....

Biographical information on a sample of renowned U.S. inventors is combined with information on the patents they received over their careers, and employed to highlight the implications of patent institutions for markets in inventions and for democratization. The United States deliberately...

Using patent citation data for the U.S., we test whether knowledge spillovers in biotechnology are sensitive to distance. Controlling for self-citation by inventor, assignee and examiner, cohort-based regression analysis shows that spillovers are local but that distance is becoming less...

The performance of market based environmental regulation is affected by patents and vice versa. This interaction is studied for a new type of innovation where new technologies reduce emissions of a specific pollutant but at the same time cause a new type of damage. A robust finding is that the...

Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between dirty (internal combustion engine) and clean (e.g. electric and hybrid) patents across 80 countries over several decades. We show that firms...
