One of the few states where there is any doubt about the applicability of the learned intermediary rule is Wisconsin. That’s primarily because the rule has never been addressed (one way or the other) by any Wisconsin state appellate court. The Wisconsin cases applying the rule have been federal district courts applying Wisconsin law. See Menges v. Depuy Motech, Inc., 61 F. Supp.2d 817, 830 (N.D. Ind. 1999) (applying Wisconsin law); Monson v. AcroMed Corp., 1999 WL 1133273, at *20 (E.D. Wis. May 12, 1999); and Lukaszewicz v. Ortho Pharmaceutical Corp., 510 F. Supp. 961, 963 (D. Wis. 1981),modified on other grounds, 523 F. Supp. 206 (D. Wis. 1981).
