Pfizer Inc., the world's largest drugmaker, sued Canadian generic-drug company Cobalt Pharmaceuticals Inc. alleging infringement of a U.S. patent for Lipitor, a medicine used to lower cholesterol. "Pfizer will be irreparably harmed" if a judge doesn't stop Cobalt's infringement, Pfizer said in the suit filed yesterday in Delaware.
The company also seeks legal fees and expenses. Lipitor, the world's best-selling drug, logged US$9.2-billion in sales in the first nine months of 2007, or 26% of New York-based Pfizer's revenue. In the lawsuit, Pfizer asked a judge to stop Cobalt from selling a copy until the patent expires in June, 2011.
Remarks: This is the preliminary information available with me. As soon as I will get the detailed information I will update my blog w.r.t this topic.
