OraSure Technologies and Schering-Plough to Settle Patent Infringement Litigation

OraSure Technologies, Inc. (NASDAQ:OSUR) today announced that an agreement has been reached on the principal terms to settle its pending patent infringement litigation against Schering-Plough Healthcare Products, Inc. (NYSE:SGP). The settlement is subject to completion and execution of a final settlement agreement.

Under the terms of the settlement, Schering-Plough will receive a license to OraSure’s patents in the U.S. OTC market and OraSure will receive payments of past and future royalties. “We are pleased that a settlement has been reached in our pending litigation with Schering-Plough,” said Douglas A. Michels, President and CEO of OraSure Technologies.

The litigation was commenced in 2004 when OraSure filed a lawsuit in the U.S. District Court for the Eastern District of Pennsylvania alleging that Schering-Plough’s manufacture and sale of its Dr. Scholls® Freeze Away® cryosurgical wart removal product in the U.S. over-the-counter market infringed several OraSure patents. Because an agreement on settlement terms has been reached, this matter was administratively dismissed by the District Court.
