Will Delaware Be Different? An Empirical Study Of Tc Heartland And The Shift To Defendant Choice Of Venue, Ofer Eldar, Neel U. Sukhatme

Georgetown Law Faculty Publications and Other Works

Why do some venues evolve into litigation havens while others do not? Venues might compete for litigation for various reasons, like enhancing their judges’ prestige and increasing revenues for the local bar. This competition is framed by the party that chooses the venue. Whether plaintiffs or defendants primarily choose venue is crucial because, we argue, the two scenarios are not symmetrical.

The Supreme Court’s recent decision in TC Heartland LLC v. Kraft Foods LLC illustrates this dynamic. There, the Court effectively shifted venue choice in many patent infringement cases from plaintiffs to corporate defendants. We use TC Heartland to empirically …

Trends In Private Patent Costs And Rents For Publicly-Traded United States Firms, James Bessen, Peter Neuhausler, John L. Turner, Jonathan Williams

Faculty Scholarship

We use detailed data to estimate the private costs and private rents of United States patents for publicly-traded firms. In analyzing costs, we first introduce a novel theoretical model to interpret our estimates. We then combine lawsuit data from Derwent Litalert with non-practicing entity (NPE) lawsuits collected by Patent Freedom, and use an event-study approach to estimate losses suffered by alleged infringers during 1984-2009. To estimate rents, we combine patent data from the USPTO and EPO with financial data from COMPUSTAT, and use market-value regressions to estimate the value of patent rents for publicly-traded US firms during 1979-2002. We find …

Certain Patents, Alan C. Marco, Saurabh Vishnubhakat

Faculty Scholarship

This Article presents the first in a series of studies of stock market reactions to the legal outcomes of patent cases. From a sample of patents litigated during a 20-year period, we estimate market reactions to patent litigation decisions and to patent grants. These estimates reveal that the resolution of legal uncertainty over patent validity and patent infringement is, on average, worth as much to a firm as is the initial grant of the patent right. Each is worth about 1.0-1.5% excess returns on investment. There are significant differences between such market reactions before and after the establishment in 1982 …
