On November 13, 2018, Justin Oliver published "The PTAB's New Claim Construction Standard: Will the Real Impact Please Stand Up" in Intellectual Property Strategist. Here is an excerpt:
Beginning on Nov. 13, 2018, the U.S. Patent and Trademark Office (USPTO) will cease to apply the broadest reasonable interpretation (BRI) standard for newly-filed IPR, PGR, and CBM trials under the America Invents Act (AIA). Instead, the USPTO will begin "using the same claim construction standard that would be used to construe the claim in a civil action[,] … including construing the claim in accordance with the ordinary and customary meaning of such claim … and the prosecution history pertaining to the patent." The new rules also state that the USPTO will consider "[a]ny prior claim construction determination concerning a term of the claim in a civil action, or a proceeding before the International Trade Commission, that is timely made of record."
