Santarus Receives Notice of European Patent Issuance.

SAN DIEGO -- Santarus, Inc. (Nasdaq:SNTS), a specialty pharmaceutical company, today announced that it has received a notice from the European Patent Office (EPO) that no third party oppositions were filed against EPO Patent Grant No. 1246622, relating to pharmaceutical compositions in the form of a non-enteric coated tablet and comprising proton pump inhibitors (PPIs) and one or more buffers. A notice of the publication of the grant of the EPO patent application was issued by the EPO on September 27, 2006 and the period of opposition required under European patent law expired on June 27, 2007. The European patent expires in January 2021 and is licensed to Santarus under its license agreement with the University of Missouri.

"The issuance of the European patent expands our portfolio of licensed patents issued outside the U.S., including those in Australia, Mexico, New Zealand, Russia, Singapore, South Africa and South Korea," said Gerald T. Proehl, president and chief executive officer of Santarus, Inc. "As we further expand the patent portfolio for our immediate-release PPI technology, we are continuing to evaluate potential licensing opportunities with pharmaceutical companies that have international commercialization capabilities."

Santarus has an exclusive, worldwide license agreement with the University of Missouri for patents and pending patent applications relating to specific formulations of PPIs with antacids and other buffering agents. Currently five U.S. patents have been issued and several U.S. patent applications are pending and are subject to this license. The five issued patents, which expire in July 2016, generally cover pharmaceutical compositions combining PPIs with buffering agents, such as antacids, and methods of treating gastrointestinal disorders by administering solid or liquid forms of such compositions.
