The United States Patent and Trademark Office is publishing a final rule revising the claim construction standard used by the Patent Trial and Appeal Board (the “Board”) in inter partes review, post-grant review, and covered business method patent review proceedings. The Board will no longer interpret claims under the broadest reasonable interpretation standard and will instead use the claim construction standard enunciated in Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc) and its progeny and followed by federal courts and the United States International Trade Commission (“ITC”). The changes to the claim construction standard will only apply to proceedings in which a petition is filed on or after the effective date of the final rule.
