In this paper, we aim to better understand the institutional authority of the Federal Circuit as a source of law as well as the influence of pro-patent and anti-patent ideological forces at play between the Supreme Court, Federal Circuit, and the district courts. Our specific focus is on the district courts and how they cite Federal Circuit precedent relative to Supreme Court precedent to support their decisions, whether they be pro-patent or anti-patent.

We then introduce a new methodology that is intuitive, easy to use, and, most importantly, allows scholars systematically to assess problems of bias and confounding. This methodology—known as causal directed acyclic graphs—will help empirical researchers to identify true cause and effect relationships when they exist and, at the same time, posit statistical models …
