I introduce and analyze an equilibrium model of discovery, innovation, patenting and infringement. Firms that innovate must adapt complementary inputs, and are ex ante uncertain about whether adaptations will be costly and whether they will infringe other patents. If adaptation requires...

This paper studies the problem of partnership dissolution in the context of asymmetric information. Past work shows that the initial share allocation, interdependence of partners’ valuations, and asymmetric control all affect the possibility of efficient dissolution. In this paper, I show, in...

In 1982, the US Congress established the Court of Appeals for the Federal Circuit (CAFC) as the sole appellate court for patent cases. Ostensibly, this court was created to eliminate inconsistencies in the application and interpretation of patent law across federal courts, and thereby mitigate...

This paper examines the impact of three patent damage regimes on licensing and competition between a patentee and imitator. We focus on product patents in a differentiated, duopoly setting. Neither per-unit royalties nor fixed fees under efficient licensing are unique in equilibrium. As a...

We use structural break analysis to estimate rates of patent validity and infringement in decisions on the merits in United States Courts over 1929-2006. We separately estimate these rates for District Court and Appeals Court decisions. We find multiple structural breaks in both validity and...

We identify the rate of off-label use of prescription drugs in the United States during 1993-2008 using Detection Controlled Estimation. We find the rate rises from 29.9% to 38.3% during this period. Off-label prescribing increases when there are fewer FDA-approved alternatives and a patient's...

This paper describes a data set built to analyze patent litigation in the United States during 1929-2006. The data include all patents in published district court and appellate court decisions in which validity and/or infringement are at issue. We collect numerous patent-specific variables and...

We analyze technology investment and adoption by a product developer who faces uncertainty over whether any existing patent covers a new technology. If there is a patent, the (non-producing) patentee may choose to “lurk”—i.e., to strategically delay enforcement—hoping that the developer...
