BLAST is the gold standard for biological sequence search, but when it comes to patents, it falls short.
Why doesn’t a tool used by scientists worldwide answer a simple IP question like: “Is this sequence at least 95% identical?”
In this article, our Lead Software Developer shares his expert insight on how we extended BLAST to meet real patent search needs, eliminating manual filtering, reducing errors, and improving result completeness.
From fragment detection to variant identification, we break down real-world scenarios and show how it works in practice.
