1Opinion of the Court
LOURIE, Circuit Judge.
NEC Corporation and NEC Information Systems, Inc. (collectively “NEC”) appeal from the decision of the United States District Court for the Eastern District of Louisiana denying its motion for Judgment as a Matter of Law (JMOL) that reexamined claims 1 and 2 of Laitram’s U.S. Patent 3,952,311 are not identical in scope to original claims 1 and 2. See Laitram Corp. v. NEC Corp., Civ. A. No. 89-1571-N, 1997 WL 539890 (E.D.La. Sept. 2, 1997). Because we conclude that the scope of the claims was substantively changed by amendment during reexamination, we reverse.
