Late last month, two entities associated with Brian Yates—who oversaw NPEs filing more than 500 patent infringement suits in 2015-2017, and who now has ongoing enforcement efforts in China—assigned patent portfolios to an apparent Delaware NPE controlled by an experienced licensing professional. The transacted portfolios include two patents asserted in a Yates campaign that hit McAfee, ForeScout Technologies, Fortinet (Bradford Networks) and Pulse Secure before ending a mere six months after launch.
