While patent law is my core area of scholarly interest, I have also studied the use of legal scholarship by the courts. My co-author Lee Petherbridge from Loyola-LA and I have conducted several comprehensive empirical studies using large datasets on the issue. More precisely, we have analyzed how often federal courts cite to law review articles in their decisions. We have empirically analyzed the issue from a variety of angles. We have studied the use of legal scholarship by the U.S. Supreme Court (available here), by the regional U.S. Courts of Appeals (study available here), and by the Federal Circuit (available here). I won’t recount the finding of those studies here. Instead, I will report some new information and ask readers for potential explanations of the data.
