U.S. Court of Appeals for the Fourth Circuit
Filterite Corporation, a Body Corporate of the State of Maryland v. Tate Engineering, Inc., and the Carborundum Company, 447 F.2d 62 (4th Cir. 1971)
170 U.S.P.Q. (BNA) 190; 1971 U.S. App. LEXIS 9963
Filterite Corporation, a Body Corporate of the State of Maryland v. Tate Engineering, Inc., and the Carborundum Company
Opinion
Filterite Corporation, assignee of United States Letters Patent No. 3,356,-226, brought this action alleging infringement of its patent. The District Court, 318 F.Supp. 584, held the patent valid, but not infringed because of differences between the method of construction of the accused filter units and the specifications of the patent claim. Upon careful consideration of the record, the briefs, and oral arguments, we affirm the judgment of the District Court.
Affirmed.
