Description
Appealed from: U.S. District Court for the Northern District of Iowa Judge Mark W. Bennett Opinion for the court filed by Circuit Judge SCHALL. Opinion concurring-in-part, dissenting-in-part filed by Circuit Judge DYK. Dethmers Manufacturing Company, Inc. (""Dethmers"") appeals the decision of the United States District Court for the Northern District of Iowa that granted Automatic Equipment Manufacturing. Co.'s (""Automatic's"") motion for summary judgment that United States Patent No. Re. 35,482 (the ""reissue patent""), owned by Dethmers, is invalid. Dethmers Mfg. Co. v. Automatic Equip. Mfg. Co., 23 F. Supp. 2d 974 (N.D. Iowa 1998) (""Dethmers I""). Automatic cross-appeals the court's grant of Dethmers' motion for summary judgment of non-infringement of Automatic's U.S. Patent No. 5,356,166 (the "" '166 patent""). Dethmers Mfg. Co. v. Automatic Equip. Mfg. Co., 70 F. Supp. 2d 944 (N.D. Iowa 1999) (""Dethmers II""). Final judgment pursuant to these decisions was entered under Rule 54(b) of the Federal Rules of Civil Procedure. Dethmers Mfg. Co. v. Automatic Equip. Mfg. Co., No. C96-4061MWB (N.D. Iowa Nov. 3, 1999). With respect to Dethmers' appeal, we hold that some, but not all, of the claims of the reissue patent are invalid. With respect to Automatic's cross-appeal, we conclude that the court correctly decided that prosecution history estoppel bars Automatic's assertion against Dethmers of infringement of the '166 patent under the doctrine of equivalents. We therefore affirm-in-part, reverse-in-part, and remand.
