    Company Wins Summary Judgment In Patent Litigation

    New York, NY - Kenyon & Kenyon LLP client KV Pharmaceutical Company has announced that the United States District Court for the Eastern District of Missouri has granted its motions for summary judgment in a patent infringement case filed against it by AstraZeneca. The case arose from KV’s submission of ANDAs seeking approval to market generic formulations of AstraZeneca’s beta-blocker Toprol-XL (metoprolol succinate extended-release tablets) The case is In re Metoprolol Succinate Patent Litigation, MDL-1620-RWS.

    The Court granted the motions filed by KV Pharmaceutical Company and its co-defendants Andrx Corporation and Eon Labs for summary judgment of invalidity and unenforceability of both patents that were asserted by AstraZeneca (U.S. Patents 5,001,161 and 5,081,154). Both patents were held invalid, as well as being held unenforceable for inequitable conduct committed by AstraZeneca during prosecution of the patents before the U.S. Patent and Trademark Office.

    According to a statement issued by AstraZeneca, sales for Toprol-XL in the U.S. in 2005 were $1.291 billion. KV reported in its press release that it believes it has the first-filed ANDA pending at the FDA for the 100mg and 200mg dosages, and that sales of the 100mg and 200mg strengths represent nearly half of the total volume.
