Sampo IP’s ongoing campaign now includes Blackboard and Salesforce after the Marathon Patent Group-subsidiary filed a single suit against the two companies, joining them as co-defendants. The complaint accuses the “Blackboard Learn for Salesforce” product, developed by Blackboard but run on Salesforce, of infringing the three patents-in-suit (6,161,149; 6,772,229; 8,015,495). The asserted patents relate to communcation and collaboration across computer channels, something the Blackboard product allegedly provides by linking users’ computing devices to a central Salesforce agent. The asserted patents originated with GroupServe and were assigned to an IPNav subsidiary in June 2012 before being transferred to Sampo in March 2013. Sampo’s patent company is involved in an ongoing “strategic partnership” with IPNav. 11/7, Eastern District of Virginia, 2:13cv00601
