They have multiple patents in process, that must be a different one. Because per the PR and 8k filed with the SEC, they received notice of allowance on 10/19/2023.
The NOA linked above in the sticky notes is the NOA granted for the TRADEMARK of the B.D.T.P. (Blackstar Digital Trading Platform).

BEGI has a handful of patents and trademarks that either have been or are in the process of being NOA/officially issued by the USPTO.
