Wilmington: Sanofi-Aventis SA, France’s largest drug maker, sued Indian rival Sun Pharmaceutical Industries Ltd, seeking to stop a generic copy of the Taxotere cancer drug.
Sun is pursuing approval from the US Food and Drug Administration (FDA) to market two dosage forms of the drug before the patents expire in 2012, according to the complaint filed on 21 August in the federal court in Delaware.
In a letter to FDA, Sun claimed that Sanofi’s patents were invalid and unenforceable, according to the complaint.
