Oral argument: Dec. 5, 2011
Appealed from: United States Court of Appeals for the Federal Circuit (April 14, 2010)
Petitioner Caraco Pharmaceutical Laboratories, a generic drug manufacturer, sought FDA approval to market the diabetes drug repaglinide. Pursuant to the Hatch-Waxman Act's expedited FDA application process for generic drugs, Caraco certified that its drug label would not conflict with Respondent Novo Nordisk’s patented repaglinide-metformin use combination. Relying on Novo’s description of its patent, the FDA denied the certification. Caraco invoked the Act’s counterclaim provision to compel Novo to revert to a narrower patent description. The United States Court of Appeals for the Federal Circuit found that Caraco could not assert the counterclaim. Caraco argues that the Federal Circuit’s reading of the counterclaim provision is incorrect and that the purpose of the counterclaim provision—to “correct” misleading patent descriptions—supports reversal. Novo asserts that the statute plainly permits a counterclaim only if Novo’s patent does not claim any approved method of use. The Supreme Court’s reading of the counterclaim provision may affect healthcare costs and the generic drug manufacturing industry.
