Title: Changes to the Claim Construction Standard for Interpreting Claims in Trial Proceedings Before the Patent Trial and Appeal Board 

The United States Patent and Trademark Office (USPTO or Office) changes the claim construction standard for interpreting claims in inter partes review (IPR), post-grant review (PGR), and the transitional program for covered business method patents (CBM) proceedings before the Patent Trial and Appeal Board (PTAB or Board). In particular, the Office replaces the broadest reasonable interpretation (BRI) standard for construing unexpired patent claims and proposed claims in these trial proceedings with a standard that is the same as the standard applied in federal district courts and International Trade Commission (ITC) proceedings. The Office also amends the rules to add that the Office will consider any prior claim construction determination concerning a term of the involved claim in a civil action, or an ITC proceeding, that is timely made of record in an IPR, PGR, or CBM proceeding.
