Narrative Opinion Summary
The case involves an appeal by Hoechst-Roussel Pharmaceuticals, Inc. against a decision by the U.S. District Court for the Eastern District of Virginia, which denied Hoechst's request for a patent term extension under 35 U.S.C. § 156 for its patent on a compound related to the drug COGNEX®. The district court ruled in favor of the Commissioner of Patents and Trademarks, Bruce A. Lehman, finding that Hoechst's patent did not cover the active ingredient tacrine hydrochloride, approved by the FDA. The court emphasized that for a patent term extension under the statute, the patent must explicitly claim the approved product or its use, which Hoechst's patent did not. Hoechst argued that the term 'claims' should be interpreted to include any product that would infringe the patent's claims, but the court upheld the ordinary meaning of 'claims' as defining the scope of patent rights, rejecting Hoechst's broader interpretation. The appellate court reviewed the district court's summary judgment de novo, focusing on the statutory interpretation of 'claims' and found that Hoechst's legislative history arguments did not justify diverging from the statute's clear language. Consequently, the court affirmed the district court's judgment, denying the patent term extension and maintaining the requirement for clear patent claims under § 156.
