In this paper, we offer a novel explanation to the surge in patenting bserved during the last years. With low … patentability standards at PTOs (Patent and Trademark Offices awarding so-called bad patents), not only “false innovators” have the … chance of being granted patents but also, and more interestingly, “true innovators” are forced to patent more intensively …

We investigate how international patent activity enables firms from emerging economies to thrive in the global … marketplace. We match Chinese customs data to US patent records, and leverage the quasi-random assignment of USPTO patent … examiners to identify the causal effect of a US patent grant on the subsequent export performance of Chinese firms. Successful …

crisis has brought the optimal design of pharmaceutical patent policy to the fore. In this paper we evaluate patent policy in … the US pharmaceutical industry. We estimate the effect of patent length and scope on generic entry prior to the expiration … of new drug patents using two quasi-experimental approaches: one based on changes in patent laws and another on the …

innovation. We study the equilibrium innovation activity under three regimes: patents, no-patents and patent pools. Patent pools … increase the probability of innovation with respect to patents, but we also find that: (1) their outcome can be replicated by a … licensing scheme in which innovators sell complete patent rights, and (2) they are dynamically unstable. We find that none of …

We exploit a reform to the UK's patent … system that introduced substantive examination to the patent application process, improving the information available to …

quality of these disclosures affects follow-on innovation. We use the plausibly exogenous assignment to patent applications of …The patent system grants inventors temporary monopoly rights in exchange for a public disclosure detailing their … innovation. These disclosures are meant to allow others to recreate and build on the patented innovation. We examine how the …
