The fee for the terminal disclaimer that was previously submitted has been applied to the filing of the replacement or supplemental terminal disclaimer. If the disclaimer fee set forth in 37 CFR 1.20(d) has been increased since the fee was previously paid, then patent owner must pay the difference between the increased fee and the amount previously paid. Therefore, patent owner's payment of another terminal disclaimer fee under 37 CFR 1.20(d) is not required or is not required for the full amount. Patent owner may request a refund of any payment more than the terminal disclaimer fee required when the replacement or supplemental terminal disclaimer was filed by submitting a written request for a refund and a copy of this Office action to: Mail Stop 16, Director of the United States Patent and Trademark Office, P.O. Box 1450, Alexandria, Virginia 22313-1450.
