The Compendium of Federal Circuit decisions is a a database created to both standardize and analyze decisions of the United States Court of Appeals for the Federal Circuit.  The Compendium includes all opinions, orders, and summary affirmances that originated in a federal district court or the Patent and Trademark Office and were released on the Federal Circuit’s website—essentially all opinions since 2004 and all summary affirmances since 2007, along with numerous orders and other documents.  Multiple fields are coded in a standardized format that will allow future researchers to avoid recollecting fundamental fields such as case names or opinion dates.  The database also has the capacity for expansion, and new information about the decisions can easily be added.  Public access to the database is provided in an easy-to-use web-based interface that allows for immediate visualization of data.

The Compendium may be accessed here: https://fedcircuit.shinyapps.io/federalcompendium/.  Comments or corrections can be sent to jason-rantanen@uiowa.edu.  For additional descriptions of methodology and metrics as of early 2018, see Jason Rantanen, The Landscape of Modern Patent Appeals, 67 Am. U. L. Rev. 985 (2018).
