# 1.198 Reopening after a final decision of the Patent Trial and Appeal Board.

When a decision by the Patent Trial and Appeal Board on appeal has become final for judicial review, prosecution of the proceeding before the primary examiner will not be reopened or reconsidered by the primary examiner except under the provisions of § 1.114 or § 41.50 of this title without the written authority of the Director, and then only for the consideration of matters not already adjudicated, sufficient cause being shown.
