NOTE 9: - LITIGATION

 

On May 31, 2017, United Therapeutics Corporation (“United”) filed a motion to appeal with the U.S. Court of Appeals for the Federal Circuit regarding a Final Written Decision of the Patent Trial and Appeal Board (the “PTAB”) for an IPR petition filed by the Company on October 21, 2015. The IPR petition sought to invalidate U.S. Patent No. 8,497,393 (the “‘393 Patent”) owned by United, which expires in December 2028 and covers a method of making treprostinil, the active pharmaceutical ingredient in United’s drug, Remodulin. The Final Written Decision for the IPR petition issued by the PTAB on March 31, 2017, found that all claims of the ‘393 Patent are not patentable. The Appellate Court heard oral arguments from the parties on November 7, 2017.
