In September, RPX noted the assignment of over 20 issued US patents from Altaba Inc. (f/k/a Yahoo! Inc.), through Excalibur IP, LLC, to Eureka Database Solutions, LLC, an affiliate of Monument Patent Holdings, LLC. Three of the patents from the largest family of those transacted patents, generally related to annotating and locating “items of interest” within multimedia data, have now been asserted in litigation: Eureka Database has filed separate lawsuits against Kaltura (1:17-cv-01529) and Panopto (1:17-cv-01530). At issue are the defendants’ video search features (Kaltura’s Video Discovery and Search and Panopto’s Smart Search).
