Sampo IP, a unit of patent acquisition and licensing company Marathon Patent Group, filed suit Monday in Delaware federal court accusing Facebook Inc., Intuit Inc., Amazon.com Inc., LinkedIn Corp. and eBay Inc. of infringing on “communications systems and methods” covered in three Sampo patents.

According to a Marathon release, “The lawsuit alleges that the defendants have infringed, and continue to infringe, the claims of the patents in suit by using the accused communications systems and methods covered by the claims of the asserted patents.”

The covered invention involves transmitting, receiving and distributing information among peripheral computing devices using a central agent.

Alexandria, Va.-based Sampo is suing Facebook, Intuit and Amazon for infringement related to U.S. Patents 6,772,229, 6,161,149 and 8,015,495—each is entitled “Centrifugal Communication and Collaboration Method.” The entity is suing LinkedIn and eBay for infringement related to its U.S. Patents 6,772,229 and 8,015,495.

Marathon is headed by Chairman and CEO Doug Croxall, former chairman and CEO of LVL Patent Group, also based in Alexandria. Farnan LLP of Delaware and Michcon de Reya New York are representing Sampo.

According to litigation analytics site Lex Machina, Sampo in May 2013 sued Starbucks Corp., Hewlett-Packard Co., Motorola Solutions and a host of other rcompanies in the Eastern District of Texas. The suit settled in July 2013.

Palo Alto-based Jive Software, represented by Wilson Sonsini Goodrich & Rosati, filed a declaratory judgment action in the Northern District of California, arguing the suit targeted its customers.

“Jive is the true defendant in the suit against Jive’s customers—needing to protect its customers and avoid the damaging impact of an adverse ruling against its products, and having the ability to implement any necessary design changes in the accused technology and the knowledge of an information about its accused technology,” the suit stated.
