Ranbaxy Laboratories Granted Permission To Appeal U.K. High Court Judgement On Patent Relating To Atorvastatin

LONDON, Nov. 3 /PRNewswire/ -- Ranbaxy Laboratories Limited (Ranbaxy) announces that today the U.K. High Court granted Ranbaxy permission to appeal the ruling of October 12, 2005, that its atorvastatin product would infringe Warner Lambert/Pfizer’s European patent 247 633 in the U.K*. Atorvastatin is a cholesterol-lowering drug, which is marketed by Pfizer as Lipitor.

In his October 12th judgment, Mr. Justice Pumfrey had ruled that Warner Lambert/Pfizer’s European patent 409 281 was invalid in the U.K. but that Ranbaxy’s proposed product would infringe Warner Lambert/Pfizer’s patent 247 633.

In his decision today, Mr. Justice Pumfrey granted permission to both Ranbaxy and Pfizer to appeal the respective rulings in the U.K. Court of Appeal. The outcome of both appeals is expected by the end of 2006.

Malvinder Singh, President & Executive Director of Ranbaxy Laboratories Ltd., said, “Having already been successful in invalidating one of the two key Pfizer patents relating to atorvastatin in the U.K., Ranbaxy is encouraged to have been granted the opportunity to make its case on the infringement decision on the other patent before the U.K. Court of Appeal. We remain committed to our objective of bringing an affordable generic formulation of atorvastatin to the National Health Service in the UK.”
