Liebel-Flarsheim Co. v. Medrad, Inc.

Liebel-Flarsheim Company and Mallinckrodt Inc. (collectively “Liebel”) appeal from the decision of the United States District Court for the Southern District of Ohio granting Medrad’s motion for summary judgment that four of Liebel’s patents are invalid under 35 U.S.C. §§ 112 and 102. Liebel-Flarsheim Co. v. Medrad, Inc., No. 01-CV-98-858 (S.D. Ohio Oct. 28, 2005). Medrad cross-appeals from the decision of the district court granting Liebel’s motion for summary judgment that Medrad infringed the asserted patents and that the inventorship designation on Liebel’s patents is correct. Medrad
also cross-appeals from the holding that the inequitable conduct counterclaim was moot in light of the district court’s invalidity rulings. Because we conclude that Liebel’s patents are invalid, the front-loading patents for lack of enablement and the syringe-sensing patents on anticipation, we affirm the district court’s judgment of invalidity. As a result, the cross-appeals on infringement and inventorship need not be reached. We also affirm the court’s decision that the inequitable conduct counterclaim is presently moot.
