On September 6, 2018, the Patent Trial and Appeal Board (PTAB) instituted trial on all challenged claims in an IPR filed by Unified 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.
