uspto proposes rule changes to claim construction standard in ptab proceedings

On May 8, 2018, the USPTO announced its proposed rulemaking for claim construction standard in PTAB proceedings.  The PTO proposed to amend the rules to require the PTAB to interpret the claims in IPR/PGR/CBM proceedings using the same standard as applied in federal district courts and the USITC, and to consider any prior claim construction determination concerning a term of involved claim in a civil action or ITC proceeding that is timely made in the PTAB proceeding.  The proposed changes would replace the BRI standard with the claim construction standard used in federal district courts and would be consistent with the PTO's current approach for interpreting claims in an expired patent.  Full text of the notice is available here.
