"Unfortunately, the authors did not provide details of their BLAST research. The patent database that they used contained 24,712 sequences. Yet, by querying BLAST, we obtained a database of 46,121,617 patent sequences with an average length of 560 nucleotides."
just do the BLAST yourself and see. it's a publically available database. you will find zero other exact matches. note that today in 2025 there are a shit tonne of sequences that are resequencing of covid variants so you'll have to filter those out
is that not relevant?
