Sanofi-Aventis has finally received judgment in its favour in the lawsuit of patent for the block buster drug Clopidogrel (Plavix) against Apotex Inc. This judgement will give $442 million to Sanofi. Sanofi filed its patent-infringement lawsuit against Apotex in 2002 and won a preliminary injunction against Apotex four years later. In a five-week bench trial in 2007, a judge found that Sanofi's patent on Plavix, the world's second biggest-selling drug, was valid and enforceable, and that Apotex violated the patent by making and distributing a generic form of the drug.
