U.S. Court Upholds Patent on Plavix

June 19, 2007

On Tuesday, U.S. district judge Sidney Stein in Manhattan ruled that the
patent on the world’s second best selling drug Plavix, an anti-platelet agent
for cardiovascular disease, made by Bristol-Myers Squibb and Sanofi-
Aventis is valid until November 2011.  Judge Stein found that the Canadian
company, Apotex Inc., failed to prove that the patent "is invalid or
unenforceable on any of the grounds asserted."  Apotex, the largest producer
of generic drugs in Canada, has been challenging the patent claim since
2002.  In August 2006, Apotex marketed the generic version of Plavix for
several months.  The judge today ruled that Bristol-Myers Squibb and Sanofi-
Aventis "are entitled to permanent injunctive relief and……damages”.
Generic drugs are considerably cheaper than brand-name drugs, and often
lead to a significant price plunge in the name-brand price.
