A coronavirus drug developed by Therapeutica Borealis, a pharmaceutical firm in Turku, has been granted a patent by the United States Patent and Trademark Office (USPTO). The nasal spray contains hydroxychloroquine, among other ingredients.
Earlier in May, the company said it had received approval for a patent application, based on which it expected a final patent this month.
