MONTGOMERY, Ala.--(BUSINESS WIRE)--Kowa Pharmaceuticals America, Inc. announced today that Kowa Company, Ltd., Kowa Pharmaceuticals America, Inc., and Nissan Chemical Industries, Ltd. (collectively, “Plaintiffs”) and generic drug manufacturer Apotex, Inc. and Apotex Corp. (“Apotex”) have finalized an agreement to resolve all outstanding litigation related to Livalo®(pitavastatin).
Plaintiffs had brought suit against Apotex for patent infringement based on the filing of Apotex’s ANDA seeking Food and Drug Administration (FDA) approval to market 1 mg, 2 mg, and 4 mg pitavastatin calcium tablets, generic to Livalo®. In response to this suit, Apotex had contended that the ‘993 patent was invalid as (1) anticipated based on prior art, under 35 U.S.C. § 102(b); and/or (2) obvious in view of prior art, under 35 U.S.C. § 103. Apotex also asserted non-infringement.
The Apotex litigation had been on appeal to the U.S. Court of Appeals for the Federal Circuit, along with a consolidated appeal filed by Amneal Pharmaceuticals LLP ("Amneal"), in which Apotex and Amneal have been appealing an adverse judgment entered against them in the U.S. District Court for the District of New York, in which the Court upheld the validity and infringement of U.S. Patents Nos. 5,856,336 and 8,557,993. The Apotex settlement leaves Amneal as the sole remaining appealing defendant.
Plaintiffs previously brought suit against seven other sets of generic defendants with respect to their ANDAs for generic versions of Livalo®. Pursuant to agreements that resolved those lawsuits, each of those generic defendants agreed to license to market their generic versions of Livalo® beginning on May 2, 2023, or earlier under certain circumstances. Apotex has now also agreed to license to market its generic version of Livalo® beginning on May 2, 2023, or earlier under certain circumstances.
“We are very pleased with the District Court’s rulings upholding the infringement and validity of the patents for Livalo®, and with the recent resolution of the Apotex litigation,” said Ben Stakely, Chairman, CEO and President of Kowa Pharmaceuticals America, Inc. “We look forward to continuing to supply Livalo® to patients, and will continue to actively protect and defend our intellectual property.”
