Hong Kong, India, Indonesia, Israel, Japan, Korea, Mexico, the Philippines, Russia, Singapore and South Africa. Certain of these issued patents and patent applications, if issued, will expire as late as 2033. These patent rights have been exclusively licensed for the treatment of patients with Bellerophon indications and cover methods of delivery and the drug delivery device, as well as important safety features and the ornamental design of the drug delivery device.
A primary basis for patent exclusivity is based on pending and issued in-licensed patents directed to proprietary methods of administering pulsed inhaled nitric oxide, as well as a device for delivering the same. At least one patent has been issued in the United States as well as Australia, Brazil, Canada, China, Europe, Hong Kong, Japan and Mexico. Patent applications are pending in Australia, Mexico and the United States. This patent family expires as late as 2027 in the United States and in 2026 in the other countries.
Another important basis for patent exclusivity is based on an in-licensed portfolio of patents, directed to novel nasal cannula features that we believe are necessary for the accurate, safe and efficacious administration of pulsed nitric oxide. The patent family consists of seven issued U.S. patents and issued patents in Australia, Brazil, China, Eurasia, Europe, Hong Kong, Israel, Japan, Korea, Mexico and South Africa, as well as pending applications in the United States as well as Australia, Canada, Europe, Israel, India, Japan, Korea, Mexico and South Africa. Each of these patents and patent applications, if issued, will expire in 2033 in the United States and abroad.
Another in-licensed patent family relates to features of the drug delivery canister necessary for providing drug product for use with our proprietary pulsing drug delivery device. This patent family includes at least one issued patent in each of the United States, Australia, Brazil, Canada, China, Europe, Hong Kong, Indonesia, Israel, India, Japan, Korea, Mexico, the Philippines, Russia and Singapore, as well as pending patent applications in the United States and Mexico. These pending applications, if issued, as well as the non-U.S. issued patents will expire in 2029. Two issued U.S. patents will expire in 2030.
Several other patent families directed to device and safety features are issued and pending. One U.S. issued patent directed to the valve configuration of our proprietary drug delivery device and the shape of the nitric oxide pulses will expire in 2039. Furthermore, design patents covering the ornamental designs of the intended commercial device and clinical device have been granted.
We have also filed several Company-owned patent applications relating to the use and administration of nitric oxide and devices for administering nitric oxide. These Company-owned patent families are currently pending as international PCT patent applications, US applications and/or applications in foreign countries including Argentina, Australia, Brazil, Canada, China, Eurasia, Europe, Hong Kong, India, Indonesia, Israel, Japan, Korea, Mexico, New Zealand, the Philippines, Singapore, South Africa and/or Taiwan, and any patents that issue in these families will expire in 2039, 2040, 2041 or 2043. The patent families relate to the use of inhaled nitric oxide for the improvement of right and/or left ventricular function, the use of inhaled nitric oxide for the treatment of PH-ILD, the use of inhaled nitric oxide and oxygen for the treatment of PH, and treating PH by maintaining dosing frequency and/or minimizing skipped breaths during pulsed administration of inhaled nitric oxide. Additional patent families relate to methods of administering pulsed nitric oxide, administration of nitric oxide for improvement of severe hypoxemia, administration of nitric oxide in combination with PDE-5 inhibitors, administration of nitric oxide to improve activity levels in patients having lung-related impairment, improvement in pulmonary arterial compliance with inhaled nitric oxide treatment, use of inhaled nitric oxide treatment of infection (including infection with SARS-CoV2) and treatment of COVID-19, use of inhaled nitric oxide for decreasing pulmonary arterial pressure and pulmonary vascular resistance and methods for pulsatile delivery of a gaseous drug.
In addition, the FDA has granted orphan drug designation to our nitric oxide program for the treatment of PAH and IPF, which could result in marketing exclusivity of seven years in the United States should this be the first NDA approved for inhaled nitric oxide in this indication. The active ingredient, nitric oxide, was previously approved by the FDA as a drug in a separate clinical application. Accordingly, any related patent rights will not be eligible for a patent term extension under relevant provisions of the Drug Price Competition and Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Act.
