Our analysis of the full set of cases across the chosen years confirms what we saw in the smaller sample: patent infringement litigation by patent monetization entities has risen dramatically over a remarkably short period of time. One of the most striking results is the following: in 2012, litigation by patent monetization entities now represents a majority of the patent litigation filed in the United States. Specifically, patent monetization entities filed 58% of the patent lawsuits in 2012. This is a sharp rise from 2007, when patent monetization entities filed only 24% of patent infringement litigations.
