We compare patent litigation cases across four European jurisdictions - Germany, France, the Netherlands, and the UK - covering cases filed during the period 2000-2008. For our analysis, we assemble a new dataset that contains detailed information at the case, litigant, and patent level for...

We analyze the impact of the probabilistic nature of patents on the functioning of Germany's bifurcated patent litigation system where infringement and validity of a patent are decided independently by different courts. We show that bifurcation creates situations in which a patent is held...

In diesem Beitrag wird ein Oligopolmodell der Innovationsaktivität entwickelt und mit Daten aus dem Mannheimer Innovationspanel geschätzt. Das Modell erlaubt es, bei der empirischen Umsetzung auf die Verwendung von Marktanteilsdaten und Nachfrageelastizitäten zu verzichten, die typischerweise...

Through a survey, economic value estimates were obtained on 962 inventions made in the United States and Germany and on which German patent renewal fees were paid to full-term expiration in 1995. A search of subsequent U.S. and German patents yielded a count of citations to those patents....

We explore the tail of patented invention value distributions by using value estimates obtained directly from patent holders. The paper focuses on those full-term German patents of the application year 1977 which were held by West German and U.S. residents. The most valuable patents in our data...

In Deutschland beanspruchen gleich zwei Ressorts, das Bundesministerium für Bildung und Forschung (BMBF) sowie das Bundesministerium für Wirtschaft und Technologie (BMWi) die Zuständigkeit für die deutsche Innovationspolitik. Dieses für den Bund offensichtlich bedeutsame Politikfeld...

Changing product quality poses a challenge for the computation of price indexes, in particular in technologically advanced industries. We assess the differences between traditional and quality-corrected indexes by computing hedonic and matched-model price indexes for personal computer database...

This paper investigates how patent applications and grants held by new ventures improve their ability to attract venture capital (VC) financing. We argue that investors are faced with considerable uncertainty and therefore rely on patents as signals when trying to assess the prospects of...
