MONMOUTH JUNCTION, N.J. , July 20, 2022 /PRNewswire/ -- Tris Pharma, Inc. ("Tris"), a fully integrated pharmaceutical company with a robust portfolio of CNS products announced that the U.S. Court of Appeals for the Federal Circuit (CAFC) issued its decision on July 7, 2022 upholding the validity and infringement of various patents relating to Quillivant XR® (methylphenidate HCl).

In December 2020 , the U.S. Federal District Court for the District of Delaware issued a favorable decision finding that the Quillivant XR patents were valid and that a generic methylphenidate product proposed by Actavis Laboratories FL, incorporated in its Abbreviated New Drug Application (ANDA) would infringe the asserted patents. The CAFC decision confirms the lower court finding and prevents Actavis from launching a generic version of Quillivant XR until the expiration of the patent portfolio providing exclusivity until February 2031.

As Tris's most used and fastest growing branded product, this decision will continue to allow the thousands of patients who benefit from the product to continue to do so with no interruption or change in experience for a long time.

"We are very pleased with the ruling of the CAFC, which affirms the strength of our patents protecting Quillivant XR." said Ketan Mehta , Founder and Chief Executive Officer of Tris Pharma.  "The decision validates Tris's pioneering research to develop innovative new medicines that improve the lives of patients."
