Throughout the last few years, prolific inventor and patent plaintiff Leigh M. Rothschild has consistently remained one of the top filers of NPE litigation. 2019 was no different. Last year saw over 160 defendants added to campaigns launched by plaintiffs associated with Rothschild, the campaigns spanning a wide range of technologies and now involving suits filed (and typically litigated in file-and-settle fashion) in myriad districts. A quick glance at the plaintiff’s early 2020 filings suggest that this year will see more of the same.
