This article outlines the creation of the Chief Economist’s Office at the US Patent and Trademark Office in March, 2010, and the publication of the Office’s first economics research agenda. In describing the elements of the research agenda—the role of intellectual property (IP) in economic...

Using a selection corrected probit, I estimate the probability that patents will be found valid and infringed at trial. I combine for the first time detailed adjudication data with detailed patent data. I find that the selection effects for validity adjudications and infringement adjudications...

This paper presents a mechanism for regulating pollution when industry harm--but not individual firms' contributions--is observable. The mechanism is based on a modification of Cooter and Porat's Total Liability for Excessive Harm (TLEH). We propose an alternative mechanism of Shared Social...

In this note we investigate the infringement (entry) decision for a firm facing an incumbent patent holder with uncertain patent rights. The entrant risks a dispute by entering, resulting in either a settlement (licensing) or litigation and trial. Using the litigation model described by Priest...

In this paper I present a real options model of patent litigation when patents are not perfectly enforceable. I consider both finite horizon and infinite horizon models. The theoretical results demonstrate that patent value depends not only on the underlying technology, but also on the degree of...

Lottery revenues are often touted as an independent revenue source for states. Using 32 years of state financial data, the fallacy of such thinking is demonstrated. Being the first to control for the self-selection of being a lottery state, it is found that overall tax revenues decline with...

We investigate the merger behavior of firms in the plant biotechnology sector using firm-level patent data for public and private firms in the 1980s and 1990s. Conditional logit estimation is used to estimate the probability that the firms will match in mergers and spinoffs. We calculate several...

In this note we investigate the infringement (entry) decision for a firm facing an incumbent patent holder with uncertain patent rights. The entrant risks a dispute by entering, resulting in either a settlement (licensing) or litigation and trial. Using the litigation model described by Priest...

The recent surge in U.S. patenting and expansion of patentable subject matter has increased patent office backlogs and raised concerns that in some cases patents of insufficient quality or with inadequate search of prior art are being issued. At the same time patent litigation and its costs are...
