On September 13, 2018, the Patent Trial and Appeal Board (PTAB) granted Certified Measurement’s (a Walker Innovation subsidiary) request for adverse judgment and cancellation of all instituted claims in IPR2018-00548 filed by Unified. This request comes shortly after the PTAB’s decision to institute trial for U.S. Patent 8,549,310, directed to a "method and apparatus for secure measurement certification." The ‘310 patent has been asserted in multiple cases against such companies as Yokogawa America and Centerpoint Energy.
