Landmark Networks, LLC, a subsidiary of Monument Patent Holdings, LLC, has filed suit against Electronic Arts (3:17-cv-04121) over a family of two patents (6,018,720; 6,856,966), generally related to accounting for the purchase and delivery of a product (here, gaming software) over a network. The NPE’s latest lawsuit comes on the heels of a joint stipulated dismissal (with prejudice) of its last open case, a suit against Valve, which had been transferred in May from the Eastern District of Texas to the Western District of Washington in light of TC Heartland.
