Digital designs - that is, designs for display on electronic screens - have recently burst onto the intellectual property (IP) stage. While in the U.S. a smattering of legal studies have recently addressed the question of digital design as a copyright-, trademark- and patent-eligible subject...

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...

How do intellectual property rights influence academic science? We investigate the consequences of the introduction of software patents in the U.S. on the publications of university researchers in the field of computer science. Difference-in-difference estimations reveal that software scientists...

Innovation is commercialization of technology. Imperfections in markets for technology should leave marks on physical investments for innovation. Two types of transaction costs could affect innovative investments: royality stacking and hold-up threats. Backward references in firm's patent...

Based on a sample of research units in science and engineering at German universities, this study reports survey evidence showing that research grants impact research content. Research units that receive funds from industry are more likely to source ideas from the private sector. The higher the...

This study shows for a large sample of R&D-active manufacturing firms that collaborative R&D has a positive effect on firms' patenting in terms of both quantity and quality. When distinguishing between alliances that aim at joint creation of new knowledge and alliances that aim at exchange of...

This article analyzes how the perceived effectiveness of intellectual property protection and competitive pressure affect firms' innovation strategy choices, concretely, whether to abstain from innovation, to introduce products that are known in the market but new to the firm (imitation) or to...

Innovators seek to protect their intellectual assets by patenting them, at the same time trying to avoid any disclosure of critical knowledge. Given that a patent specification has to include a clear description of the patented matter so that anybody skilled in the art is enabled to reproduce...

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...
