In order to file a priority patent, you must also submit a fast track application to the FDA.
SBFM stated they submitted a priority patent on 5/22 to the US Patent Office.
Under the pilot program for covid-19, you must submit both. SBFM submitted a New Drug Application along with a new patent.
The only way to be eligible for fast track and priority is if it is a new patent. A continuing patent is not eligible.
SBFM submitted a new patent and met all the requirements for eligibility, fast tracking and priority filing of patent & FDA approval.
US Patent Office & FDA have different time frames.
