Bayer Schering Pharma, AG v. Lupin, Ltd., No. 11-1143 (Fed. Cir. 2012)
Annotate this Case
A drug manufacturer can obtain FDA permission to market a generic version of an approved drug by Abbreviated New Drug Application (ANDA), rather than full New Drug Application (NDA). It is an act of infringement to file an ANDA for a drug or use of the drug claimed in a patent, 35 U.S.C. 271(e)(2)(A). Every NDA must identify every patent that could reasonably be asserted in an infringement action, 21 U.S.C. 355(b)(1), for publication in the Orange Book. An ANDA for a generic drug must address each patent in the Orange Book that relates to that drug. For patents that will not expire prior to proposed marketing, the applicant can include a statement that the applicant is not seeking approval for the method of use claimed in the patent or can certify that the patent is invalid or will not be infringed. Bayer markets Yasmin, an oral contraceptive, approved by NDA in 2001. Defendants filed ANDAs to market generic versions and certified that three patents would not be infringed, arguing that their ANDAs related only to contraceptive use and not to claimed methods for treating hirsutism or acne or reducing water retention. The district court entered judgment of noninfringement. The Federal Circuit affirmed.
