The fray between Fortress Investment Group LLC and Erich Spangenberg, over the transfer of a single patent currently active in litigation against Amazon, has now migrated from New York to Texas. The patent-at-issue is one among many assigned by Marathon Patent Group, Inc. to Fortress in 2017 after the NPE failed to repay Fortress $15.99M in debt financing. Rensselaer Polytechnic Institute (RPI) developed the patent, and it was the subject of litigation against Apple that ended in a reported $24.9M settlement in 2016.
