Currently available USPTO records suggest that Prism Technologies Group, Inc., a publicly traded NPE, still holds more than five dozen US patent assets; however, a new suit filed by Auth Token LLC calls at least some of those holdings into question. Auth Token filed separate lawsuits against Advent International (IDEMIA) (6:21-cv-00351), Feitian Technologies (6:21-cv-00350), JCB (6:21-cv-00352), UBIVELOX (6:21-cv-00353), and Yubico (6:21-cv-00354), pleading that it is the “assignee of all right, title and interest” in two patents-in-suit that assignment records still list as held by Prism. The accused products are EMV “smart cards”.
