SILVER SPRING, Md. and RESEARCH TRIANGLE PARK, N.C., Feb. 18, 2016 /PRNewswire/ -- United Therapeutics Corporation (NASDAQ: UTHR) announced receipt of a Paragraph IV Certification Notice Letter on February 18, 2016 from Actavis Laboratories FL, Inc. (Actavis) advising that Actavis has submitted an Abbreviated New Drug Application (ANDA) to the U.S. Food and Drug Administration (FDA) requesting approval to market a generic version of the 2.5 mg strength of Orenitram® (treprostinil) Extended-Release Tablets.

The Notice Letter states that the ANDA contains a Paragraph IV Certification alleging that these patents are not valid, not enforceable, and/or will not be infringed by the commercial manufacture, use or sale of the proposed product described in Actavis ANDA submission.
United Therapeutics intends to vigorously enforce its intellectual property rights relating to Orenitram, including the patents mentioned above, which are listed in FDA's Approved Drug Products with Therapeutic Equivalence Evaluations list (the Orange Book).
