This chapter reviews studies of non-practicing entities (NPEs) (aka “patent trolls”) and their effect on the United States patent system. The information presented is not intended to pass judgment or persuade readers that NPEs are definitively beneficial or detrimental to the patent system, but rather seeks to inspire readers to assess the issue of NPEs from a more informed and detailed perspective. There are varying opinions and interpretations regarding NPEs, their behavior, and the effects of their behavior. Current empirical studies offer mixed evidence and conclusions regarding the effect of NPEs on the patent system. After reading this chapter, a researcher will be capable of determining substantial differences in the behavior and characteristics amongst the various types of NPEs. This would further help the researcher to differentiate which kinds of NPEs’ behavior are detrimental and which are favorable to the patent system.
