extended for the period of delay, but in no case more than 5 years.

(2) EXTENSION FOR APPELLATE REVIEW. —If the issue of a patent

which an appeal is filed under section 134 or 141 of this title, or on

patent is not subject to a terminal disclaimer due to the issuance of

another patent claiming subject matter that is not patentably distinct from

that under appellate review. If an application is remanded by a panel of the

Patent Trial and Appeal Board and the remand is the last action by a panel

of the Patent Trial and Appeal Board prior to the mailing of a notice of

allowance under

Uruguay Round Agreements Act, Public Law 103-465, 108 Stat. 4809, 4983-85

(1994), and a final decision in favor of the applicant under paragraph

(c)(3) of this section. A remand by a panel of the Patent Trial and Appeal

Board shall not be considered a decision in the review reversing an adverse

determination of patentability as provided in this paragraph if there is

filed a request for continued examination under

35 U.S.C.

act with due diligence. In determining the due diligence of an applicant,

the Director may examine the facts and circumstances of the applicant’s

The twenty-year term of a patent issuing from an application filed on or

after June 8, 1995, and before May 29, 2000, may be extended for a maximum of five years

for delays in the issuance of the patent due to interferences, secrecy orders and/or

successful appeals to the Patent Trial and Appeal Board (Board) or the federal courts in

attributable to appellate review within three years of the filing date of the first

national application for patent, and the period of extension for appellate review will be

reduced by any time during which the applicant did not act with due diligence. The patent

term extension that may be available under

term extension granted as a result of administrative delay pursuant to

37 CFR 1.701

printed on the face of the patent in generally the same location as the terminal disclaimer

(i.e., from the filing date, continuing data, issue date and any patent term extensions

printed on the patent).

If applicant disagrees with the patent term extension information printed

on the front page of the patent, applicant may request review by way of a petition under

37 CFR

1.181
