The amendment filed [1] after a decision by the Patent Trial and Appeal Board is not entered because prosecution is closed. As provided in 37 CFR 1.198 , prosecution of the proceeding before the primary examiner will not be reopened or reconsidered by the primary examiner after a final decision of the Board except under the provisions of 37 CFR 1.114 (request for continued examination) or 37 CFR 41.50 without the written authority of the Director, and then only for the consideration of matters not already adjudicated, sufficient cause being shown.
