The settlement follows the September 30, 2026, ruling by the U.S. District Court for the District of Delaware (the Court) that claims 1 and 14 of U.S. Patent No. 11,826,327 (the ’327 patent) are valid and infringed by Liquidia. These claims generally cover treatment of pulmonary hypertension associated with interstitial lung disease (PH-ILD) with inhaled treprostinil, including dry powder formulations. As part of the settlement, Liquidia has agreed not to appeal the Court’s ruling. In addition, Liquidia has submitted a supplement to remove the PH-ILD indication from YUTREPIA’s label and no longer promotes it for PH-ILD.
