Key Financial Metrics
The filing does not provide revenue, profit, cash flow, margins, debt, liquidity, or other financial metrics.
Material Changes and Legal Developments
- On March 21, 2023, the U.S. Court of Appeals for the Federal Circuit scheduled oral argument for May 3, 2023, regarding both parties’ appeals of the District Court decisions in the Hatch-Waxman Litigation.
- The District Court previously found certain claims of U.S. Patent No. 9,593,066 invalid and found the remaining asserted claims not infringed by Liquidia.
- The District Court found the asserted claims of U.S. Patent No. 10,716,793 valid and infringed, and ordered that FDA approval of YUTREPIA could not become effective before expiration of that patent, expected in 2027.
- The scheduled oral argument will address only the District Court appeals and will not address the separate Patent Trial and Appeal Board decision invalidating all claims of the ’793 Patent based on known prior art cited by Liquidia.
- United Therapeutics has publicly stated that it intends to appeal the PTAB decision concerning the ’793 Patent. Any such appeal would be heard separately by the Federal Circuit.
Guidance, Outlook, Risks, and Unusual Items
The litigation creates uncertainty regarding the timing of potential FDA approval and commercialization of YUTREPIA. Although the District Court’s judgment contemplated a potential approval-effective date no earlier than the ’793 Patent’s expiration in 2027, the outcome may be affected by the pending appeals and the separate PTAB proceeding. The filing provides no financial guidance or quantified estimate of potential impact.
Investor Verification Points
- Confirm the outcome and timing of the May 3, 2023 Federal Circuit oral argument.
- Track the Federal Circuit’s decisions on the District Court appeals.
- Monitor any separate appeal by United Therapeutics of the PTAB’s ’793 Patent decision.
- Verify the effect of the litigation and patent proceedings on YUTREPIA’s FDA approval timing and commercialization prospects.
