Complementary Patents and Market Structure

Experimentation, Patents, Knowledge Spillovers and Market Incentives

This work addresses the question of what is the optimal patent length in a n …rm R&D race with unknown hazard rate, knowledge spillovers and variable e¤ort under general post innovation market structures. Explicit analytical solution for symmetric equilibrium strategies are given. We show that longer patents increase research intensity by increasing the competition within …rms. When post innova...

The Market for Patents in Europe

By using the PatVal-EU dataset we find that the most important determinant of patent licensing is firm size. Patent breadth, value, protection, and other factors suggested by the literature also have an impact, but not as important. In addition, most of these factors affect the willingness to license, but not whether a license actually takes place. We discuss why this suggests that there are tr...

Patents , R & D subsidies and endogenous market structure in a Schumpeterian economy

This study explores the different implications of patent breadth and R&D subsidies on economic growth and endogenous market structure in a Schumpeterian growth model. We find that when the number of firms is fixed in the short run, patent breadth and R&D subsidies serve to increase economic growth as in previous studies. However, when the number of firms adjusts endogenously in the long run, R&...
