Alcon Research, Ltd. v. Apotex, Inc., No. 11-1455 (Fed. Cir. 2012)
Annotate this CaseApotex submitted an Abbreviated New Drug Application (ANDA) to the FDA seeking approval to market a generic version of the anti-allergy eye drop Patanol. Alcon, which markets Patanol, sued Apotex for patent infringement under 35 U.S.C. 271(e)(2)(A). Alcon asserted claims 1-8 of the patent, which is listed in the Approved Drug Products with Therapeutic Equivalence Evaluations (Orange Book) entry for Patanol. The district court held that claims would not have been obvious over the prior art and were not invalid. The Federal Circuit affirmed in part. Objective evidence indicated that claims 4 and 8 would not have been obvious. Patanol’s achieving nearly 70% market share within two years of its launch, demonstrates that “the commercial success was caused by the merits of the invention as distinct from the prior art.” The remaining claims were, however, obvious. A person of ordinary skill in the art at the time of invention would have been motivated to use olopatadine to treat human eye allergies as claimed for its established antihistaminic efficacy.
The court issued a subsequent related opinion or order on August 10, 2012.
