OSI Pharmaceuticals Announces That the Prior Revocation of Its European DP-IV Patent Has Been UpheldMELVILLE, N.Y.--(BUSINESS WIRE)--Mar 18, 2008 - OSI Pharmaceuticals, Inc. (NASDAQ: OSIP) announced today that the decision of the European Patent Office (EPO) to revoke one of the Company's dipeptidyl peptidase IV (DP-IV) patents, EP0896538, claiming the use of DP-IV inhibitors to treat type II diabetes and related indications, has been upheld in appeal proceedings brought by the Company.
"We are disappointed with the outcome of the appeal proceedings. However, since the revocation applies to only one patent within our licensed DP-IV patent portfolio, any short-term loss in royalty revenue in Europe should be mitigated as additional licensed patents within the portfolio progress through the EPO examination procedure to grant," stated Anker Lundemose, M.D., Ph.D., President of (OSI) Prosidion. "The Company's DP-IV patent estate includes licensed rights to patents and patent applications claiming combinations of DP-IV inhibitors with other oral anti-diabetes drugs such as metformin."
"The Company anticipates that the vast majority of DP-IV sales in 2008 and 2009 are likely to take place in the US, therefore the financial implications of losing this patent in Europe are relatively insignificant and do not impact our prior DP-IV revenue guidance for 2008," stated Michael G. Atieh, Executive Vice President and Chief Financial Officer.
OSI through its U.K. subsidiary, Prosidion Limited, owns or has licensing rights to issued and pending patents and patent applications with claims covering DP-IV as a target for anti-diabetes therapy and related indications. The patents which are subject of these DP-IV licenses will expire between 2017 and 2019. Thirteen pharmaceutical companies, including Merck & Co., Inc., Novartis AG and Bristol-Myers Squibb Company have taken licenses to this patent estate.
