This paper reports the findings of an empirical study of patent suits involving non-practicing entities (NPEs) in the U.K. between 2000 and 2010. Overall, we find that NPEs are responsible for 11% of all patent suits filed in the U.K. during this period. Though this is a small percentage by U.S....

We analyze the extent to which private defensive litigation insurance deters patent assertion by non-practicing entities (NPEs). We study the effect that a patent-specific defensive insurance product, offered by a leading litigation insurer, had on the litigation behavior of insured patents'...

The theory of patent “hold-out” posits that frictions in the market for licensing standard-essential patents (SEPs) provide incentive for prospective licensees to opportunistically delay taking licenses. We derive empirically testable predictions from the literature supporting hold-out...

Despite the pervasiveness of patent licensing in many industries, there is a dearth of publicly available information on licensing transactions. Notably, information on price–i.e., the royalty agreed upon by licensor and licensee–is purposefully kept secret. We assess to what extent...

Because judges exercise discretion in how they handle and decide cases, heterogeneity across judges can affect case outcomes and, thus, preferences among litigants for particular judges. However, selection obscures the causal mechanisms that drive these preferences. We overcome this challenge by...
