Commitments and Contingencies	11. Commitments and Contingencies Legal Proceedings In January 2023, the Company received notice from Accord Healthcare, Inc.; Cipla USA, Inc. and Cipla Limited; Eugia Pharma Specialties Ltd.; Lupin Inc.; Mankind Pharma Ltd.; Orbicular Pharmaceutical Technologies Private Limited; and Teva Pharmaceuticals, Inc. (collectively, the “generic companies”), that they have each filed with FDA an abbreviated new drug application (“ANDA”), for a generic version of YUPELRI. The notices from the generic companies each included a paragraph IV certification with respect to five of the Company’s patents listed in FDA’s Orange Book for YUPELRI on the date of the Company’s receipt of the notice. The asserted patents relate generally to polymorphic forms of and a method of treatment using YUPELRI. In February 2023, the Company filed patent infringement suits against the generic companies in federal district courts, including the United States District Court for the District of New Jersey, the U.S. District Court for the District of Delaware, and the U.S. District Court for the Middle District of North Carolina. The suits in Delaware and North Carolina have been dismissed, as all generic companies have agreed to venue in New Jersey. The complaint alleges that by filing the ANDAs, the generic companies have infringed five of the Company’s Orange Book listed patents. The Company is seeking a permanent injunction to prevent the generic companies from introducing a generic version of YUPELRI that would infringe its patents. As a result of this lawsuit, a stay of approval through May 2026 will be imposed by FDA on the generic companies’ ANDAs pending any adverse court decision.
