Second Appeal Win against Generic Filers

ROCKVILLE, Md., Sept. 06, 2018 (GLOBE NEWSWIRE) -- Supernus Pharmaceuticals, Inc. (NASDAQ: SUPN), a pharmaceutical company focused on developing and commercializing products for the treatment of central nervous system (CNS) diseases, today announced that the U.S. Court of Appeals for the Federal Circuit affirmed the New Jersey District Court's decision that TWi infringed three Oxtellar XR Orange Book patents (U.S. Patent Nos. 7,722,898; 7,910,131; and 8,821,930) and that all three Oxtellar XR Orange Book patents are valid. This ruling follows a December 12, 2016 appellate decision affirming a decision by the same district court that Actavis also infringed Supernus’ Oxtellar XR patents.

"We are very pleased with the Appeals Court decision which marks the end of any outstanding litigation issues and generic challenges to Oxtellar XR. This decision, following the New Jersey District Court's decision in 2017, further substantiates Supernus' strong patents protecting Oxtellar XR," said Jack A. Khattar, President and CEO of Supernus.

Supernus is focused on building Oxtellar XR into a long term sustainable franchise. We continue to be excited about the future growth of Oxtellar XR including the potential label expansion to include monotherapy treatment of partial seizures of epilepsy and the development program in bipolar disorder.

Oxtellar XR is protected by eight issued patents that expire no earlier than 2027.
