Frequently asked
What is FTO Structural Triage?
A fast first-pass freedom-to-operate screen — search a target compound or synthetic route against the existing patent landscape before committing R&D or manufacturing spend.
How fast is it?
It's automated: the $10 Instant Compound Check on an arbitrary patent typically returns within about an hour.
Does it work for CDMO process patents too?
Yes — the same engine also powers a dedicated CDMO process pre-screen page.
