linked fields. Our analysis uses 1.8 million U.S. patents and their citation properties to map the innovation network and its … strength. Past innovation network structures are calculated using citation patterns across technology classes during 1975 … predictive power on future innovation after 1995. This pattern is consistent with the idea that when there is more past upstream …

This paper analyses the causal impact of Intellectual Property Rights (IPR) on pharmaceutical innovation in a panel of …. Domestic innovation is measured as citation-weighted domestic patents filed at the European Patent Office (EPO): to account for … to patent at the EPO. Results show that, in the short-run, IPR stimulate innovation. The effect for developing countries …

This paper analyzes the optimal protection strategy for an innovator of a complex innovation who faces the risk of … imitation by a competitor. We suppose that the innovation can be continuously fragmented into sub-innovations. We characterize … the optimal mix of patent and trade secrets when the innovator faces a strict novelty requirement and can only patent a …
