Excalibur IP, LLC has filed its first litigation over the former Yahoo patents that it holds, suing Spotify (1:19-cv-00165) in the District of Delaware. Four patents from three families are asserted, with the NPE targeting Spotify over its music service’s “fingerprinting” features, which identify audio data and match it to tracks in Spotify’s database and over the service’s personalized playlist features. These patents are not the first held by Excalibur IP to be litigated, however. In October 2017, Dominion Harbor Enterprises, LLC asserted assets acquired from Excalibur IP, and in June 2018, an affiliate of IP Edge LLC launched its own campaign over such patents.
