Narrative Opinion Summary
The case concerns an appeal by Abbott Laboratories against a district court ruling in favor of Novopharm Ltd. and Geneva Pharmaceuticals, Inc., regarding the expiration of United States Patent No. 4,112,097, which pertains to the drug terazosin hydrochloride. The district court concluded that the patent expired on October 14, 1995, based on the filing date of its parent application, in accordance with 35 U.S.C. § 154, and ordered Abbott to remove the expired patent from the FDA's Orange Book. Abbott had previously updated the FDA with a new expiration date following the Uruguay Round Agreements Act (URAA) changes but was challenged by the defendants seeking to produce a generic version of the drug. The court's de novo review upheld the summary judgment, affirming that the divisional application's term should be calculated from the parent application date. Additionally, the court rejected Abbott's claim that the order to remove the patent listing bypassed FDA protocols, noting its inherent authority to enforce its judgments and ensure effectiveness. The decision to affirm the district court's orders was upheld, ensuring that the expired patent listing did not impede the defendants’ FDA approval process for their generic drug applications.
