In this paper we… evaluate all substantive decisions rendered by any court in every patent case filed in 2008 and 2009 – decisions made between 2009 and 2013. We consider not just patent validity but also infringement and unenforceability. Moreover, we relate the outcomes of those cases to a host of variables, including variables related to the parties, the patents, and the court in which the case was litigated. The result is a comprehensive picture of the outcomes of modern patent litigation, one that confirms conventional wisdom in some respects but upends it in others… We used the Lex Machina database as our data source.
