Court ruling boosts United Therapeutics, slams Liquidia over pulmonary hypertension drug patent.

A Delaware court ruled in favor of United Therapeutics by upholding key patent claims on inhaled dry-powder treprostinil, used to treat pulmonary hypertension associated with interstitial lung disease. Liquidia, which markets a competing drug Yutrepia, conceded infringement, causing its stock to plunge 57%, while United Therapeutics' shares rose 12.55%. The court has yet to decide on injunctions or damages, and Liquidia plans to appeal and seek FDA label changes. This ruling threatens Liquidia's main revenue source, while United Therapeutics maintains a broader product portfolio and growth prospects despite some recent setbacks.

United Therapeutics and Liquidia's patent dispute coincides with a broad downturn in the health sector on Pluang. For readers following health stocks, here is Pluang's market snapshot as of Oct 01, 2026 22:02 WIB: out of 100 priced health-sector US stocks, 25 rose and 74 fell.
