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.
Digital Verification Systems, LLC, one of Leigh M. Rothschild’s many litigating NPEs, has filed new suits against Clover Network (2:17-cv-00153), PayAnywhere (2:17-cv-00154), PayPal (2:17-cv-00152), and Square (2:17-cv-00150). Digital Verification continues to assert a single patent (9,054,860) generally related to embedding a unique identifier in a document, and the new complaints target point-of-sale (POS) terminals and/or card reader products. The dismissal with prejudice of the lawsuit against Adobe, the last defendant from the first round of May 2016 cases, appears to have motivated Digital Verification to keep its campaign alive by filing against the latest set.
