Crestor美国专利由联邦赛道上诉法院维持

2012年12月14日星期五

AstraZeneca announced today that the Court of Appeals for the Federal Circuit has upheld the decision of the District Court, District of Delaware, finding that the US substance patent protecting CRESTOR (rosuvastatin calcium) (RE37,314 – the ‘314 patent) is valid and enforceable. The defendants may seek a rehearing and/or review by the U.S. Supreme Court. Absent a reversal of this decision, none of the Abbreviated New Drug Applications (ANDAs) filed by Apotex, Aurobindo, Cobalt, Glenmark, Mylan, Par, Sandoz, Sun, Teva and Torrent may be approved by the FDA prior to expiration of the ‘314 patent. The ‘314 patent, which expires in 2016, covers rosuvastatin calcium, the active ingredient in CRESTOR.

联邦电路还持有Apotex Corp.作为提交者承担责任,因此由地区法院的决定束缚。
