MARLBOROUGH, Mass.--(BUSINESS WIRE)--Sepracor Inc. (Nasdaq: SEPR - News) today announced that it has entered into a Settlement and License Agreement with Teva Pharmaceuticals USA, Inc. (Teva) and Barr Laboratories, Inc.

The agreement permits Barr and Teva to launch generic versions of these XOPENEX Inhalation Solution dosages under terms of a non-exclusive license commencing on February 17, 2013.

The parties agreed to promptly file a consent final judgment and dismissal in the United States District Court for the District of Delaware that will conclude this litigation.

“We are very pleased with the resolution of our patent infringement dispute with Barr and patent issues with Teva as it allows all parties to avoid the uncertainties and expenses related to patent litigation,” said Adrian Adams, President and Chief Executive Officer of Sepracor. “With the lawsuit and these patent issues behind us, Sepracor can continue to focus on fully leveraging each of our product franchises and advancing our research and development candidates.”
