On February 23, 2018, Unified filed a petition for inter partes review (IPR) against U.S. Patent 8,549,310 owned and asserted by Certified Measurement, a subsidiary of Walker Innovation and well-known NPE. The '310 patent, directed to a "method and apparatus for secure measurement certification," has been asserted in multiple cases against such companies as Yokogawa America, ABB, and Alstom.
