This appeal includes a rejection of claims [1] which are rejected on the ground of non-statutory double patenting. This rejection was not addressed in the appellant's appeal brief. Should the Board either summarily affirm or not reach the rejection and the appellant should fail to overcome the rejection with a properly filed terminal disclaimer prior to seeking judicial review either by an appeal to the U.S. Court of Appeals for the Federal Circuit ( 35 U.S.C. 141 ) or by civil action in the U.S. District Court for the Eastern District of Virginia ( 35 U.S.C. 145 ) the appeal may be dismissed by the Court for lack of jurisdiction because the claims on appeal are subject to the non-statutory double patenting rejection. Alternatively, the Court may summarily affirm the non-statutory double patenting rejection without considering other grounds of rejection challenged on the appeal.
