NPE Patent Data Project

Law Professors Christopher A. Cotropia, Jay P. Kesan, and David L. Schwartz have published a report entitled Patent Assertion Entities (PAEs) Under the Microscope: An Empirical Investigation of Patent Holders as Litigants and have made the underlying data used in the study available to the public at .

“The data reveals a much lower percentage of litigation brought by patent holding companies than other studies, finding no explosion in NPE litigation between 2010 and 2012. Instead, we find that most differences between the years—an increase in the number of patent holding companies and individual inventor suits—is likely explained by a change in the joinder rules adopted in 2011 as part of the America Invents Act.”
