Similarity is cosine over the 2,048-bit Morgan fingerprint (≈ Tanimoto). Identical fingerprints score 1.00.

Patent provenance — the patents this molecule appears in, and who filed them

Appears in 2063 patents — a generic fragment claimed broadly, so it's down-weighted as IP noise. Top by claim status then date:
