PRESS RELEASE: Canadian Court Favors Ranbaxy, Dismisses Pfizer's Application on Atrovastatin Patent

CANADIAN FEDERAL COURT FAVOURS RANBAXY

DISMISSES PFIZER'S APPLICATION ON ATORVASTATIN PATENT CA 2,220,455

Gurgaon, Haryana, India, Princeton, New Jersey, USA - September 13, 2007

Ranbaxy Laboratories Limited announced that the The Honorable Justice Snider of the Federal Court of Canada, dismissed Pfizer's application to deny issuance of a Notice of Compliance (NoC) as regards to Pfizer's Atorvastatin patent CA 2,220,455, finding that Pfizer failed to meet its burden of showing that Ranbaxy's allegation of invalidity is not justified. Atorvastatin is a cholesterol-lowering drug which is marketed by Pfizer as Lipitor®.

The Minister of Health Canada was ordered not to issue a NoC until the expiry of the other contested Pfizer Patent (CA 2,220,018). Ranbaxy will appeal this decision and remains confident in its position. In particular, Ranbaxy was successful in Norway on a similar issue regarding extraterritorial coverage of a patent, other than a process patent, outside of the country in which the patent is issued.
