Maryland IP Litigation 2008: Lawsuit Summary No. 7

By Brian Wm. Higgin

     The following lawsuit filed in the U.S. District Court for the District of Maryland pits brand and generic drug makers (source: Justia).

• #7: Forest Laboratories, Inc. v. Lupin Pharmaceuticals, Inc., No. 1:2008cv00239, filed January 28, 2008; assigned to J. Legg

     This Hatch-Waxman lawsuit involves Namenda® (memantine HCl). According to the complaint, plaintiff Forest Labs., Inc., a Delaware corporation based in New York, is the exclusive licensee of Orange Book-listed U.S. Patent No. 5,061,703. Plaintiff Forest Labs. Holdings, Ltd., is an Irish company based in Bermuda; plaintiffs Merz Pharma GmbH & Co. KGaA and Merz Pharma GmbH are German companies.

     Also according to the complaint, defendant Lupin Pharmaceuticals, Inc., a Virginia company based in Baltimore, MD, is the wholly-owned subsidiary and agent of Lupin Ltd., an Indian company based in Mumbai. Lupin Ltd. allegedly submitted, through its agent Lupin Pharma, an Abbreviated New Drug Application No. 90-051 to the FDA for approval to market generic Namenda®. It sent Forest the required notice of its ANDA submission on December 14, 2007.

     Plaintiff is asserting infringement of the ‘703 patent, and is seeking to enjoin Lupin from marketing its generic formulation before expiration of the '703 patent.

     Interestingly, plaintiffs also filed a concurrent lawsuit in the District Court for the District of Columbia because they claim not to be able to determine with certainty which one of Lupin, Inc., or Lupin Ltd. was the actual filer of the ANDA. This move was in anticipation of a jurisdictional challenge by Lupin (see related post here).
