In a February 9, 2007 press release, Sanofi-Aventis announced that it has lost its patent infringement suit against
generic drugmakers Amphastar Pharmaceuticals, Inc. and Teva Pharmaceutical
Industries Ltd., filed in the U.S. District Court for the Central District of
California. The suit relates to Sanofi-Aventis' blockbuster blood thinning drug, Lovenox®, which is covered
by patent until February 2012. According
to its press release, Sanofi-Aventis is considering its legal options going
forward. The company also notes that
while a number of manufacturers have requested FDA approval of purported
generic versions of Lovenox®, the FDA has yet to approve any such request.
