Item 8.01 Other Events.
As previously disclosed, in January 2021, Liquidia Corporation, a Delaware Corporation (the “Company”) filed a petition with the Patent Trial and Appeal Board (“PTAB”) for inter partes review of U.S. Patent No. 10,716,793 (the “’793 Patent”), seeking a determination that the claims in the ‘793 Patent are invalid. In July 2022, the PTAB ruled in our favor, concluding that based on the preponderance of the evidence, all the claims of the ’793 Patent have been shown to be unpatentable due to the existence of prior art cited by the Company in the inter partes review proceedings. In August 2022, United Therapeutics Corporation (“United Therapeutics”) submitted a rehearing request with respect to the PTAB’s decision in the inter partes review of the ‘793 Patent. The rehearing request was denied in February 2023. In April 2023, United Therapeutics appealed the decision of the PTAB with respect to the ‘793 Patent to the United States Court of Appeals for the Federal Circuit. Oral argument on the appeal was held on December 4, 2023.
On December 20, 2023, the Company issued a press release announcing that the United States Court of Appeals for the Federal Circuit affirmed the earlier decision of the PTAB. As a result of the decision, the Company will immediately seek to set aside the injunction issued by the U.S. District Court for the District of Delaware in the lawsuit filed by United Therapeutics under the Drug Price Competition and Patent Term Restoration Act (the “Hatch-Waxman Act”) and pursue final regulatory approval of YUTREPIA by the U.S. Food and Drug Administration.
A copy of the press release is filed as Exhibit 99.1 hereto and is incorporated by reference into this Item 8.01.
