India FOR IMMEDIATE RELEASE Sun Pharma: An update on generic Protonix® litigation Mumbai, July 17, 2010: Sun Pharma announced that the U.S. District Court for the District of New Jersey denied its motion for judgment as a matter of law seeking to reverse the earlier jury verdict in the patent litigation over generic Protonix®. The detailed opinion of the Court supporting this order has not yet been issued. Sun Pharma continues to believe that the patent is invalid and unenf orceable and will pursue all available legal remedies including appeals. Other claims of Sun Pharma, including patent misuse and unclean hands, that also concern the validity and enforceability of the patents remain pending. In view of this, the Court denied Wyeth and Nycomed’s motion seeking a court order to set the effective approval date for the ANDA to January 20, 2011, the first day after the end of pediatric exclusivity. As a result, Sun Pharma is not prohibited from further selling the product prior to January 20, 2011.
