Preferential Networks (Dominion Harbor) patent challenged as likely invalid

On November 29, 2017, Unified filed a petition for inter partes review (IPR) against U.S. Patent 8,577,994 owned and asserted by Preferential Networks IP, LLC, a Monument/Dominion Harbor subsidiary and well-known NPE. The '994 patent, directed to “allocating and managing bandwidth in a communication system that transfers data between devices,” has been asserted in district court against such companies as AT&T, Sprint, Comcast, T-Mobile, and Charter Communications.
