The NBER Patent Citations Data File: Lessons, Insights and Methodological Tools.

This paper describes the database on U.S. patents that we have developed over the past decade, with the goal of making it widely accessible for research. We present main trends in U. S. patenting over the last 30 years, including a variety of original measures constructed with citation data, such as backward and forward citation lags, indices of "originality" and "generality", self-citations, etc.
