In response, AstraZeneca LP (“AZP”) filed a complaint in the District of Delaware for patent infringement, and Mylan moved to dismiss for lack of personal jurisdiction. Judge Gregory M. Sleet denied the motion, finding specific jurisdiction because […]
The Eastern District of Virginia recently allowed a subsequent ANDA filer to proceed with a declaratory judgment action seeking a declaration of unenforceability of a patent that remained listed in the Orange Book after the patentee disclaimed it and requested its delisting from the Orange Book. Glenmark Generics Ltd. v. Ferring B.V., Civ. No. 3:14-CV-422-HEH […]
Last week, the Supreme Court held arguments in the closely watched case of Teva v. Sandoz. Teva won at the district court level based on claim construction arguments. The Federal Circuit reversed, affording no deference to the district courts factual findings underlying claim construction. In March, the Supreme Court granted certiorari to answer one lone […]
In a pair of opinions, both issued as Ferring B.V. v. Watson Laboratories, Inc., the Federal Circuit held that Watson’s and Apotex’s ANDA products will not infringe Ferring’s patents covering Lysteda, a tranexamic acid treatment for menorrhagia, or heavy menstrual bleeding in women.

In United Therapeutics Corp. v. Sandoz, Inc., Judge Peter G.

(Civil Action No. 3:13-cv-1617-PGS-LHG, Dkt. No. 364). As a way to reduce […]

Following […]
In Apotex, Inc. v. UCB, Inc. the Federal Circuit affirmed the Southern District of Florida’s holding that Apotex’s patent (U.S. Patent No. 6,767,556) is unenforceable for inequitable conduct.

Specifically, the Federal Circuit denied Endo’s bid for an emergency […]

Accordingly, the panel vacated and remanded the infringement ruling relying on erroneous […]
