MOLECULE SEARCH, TWO WAYS

Who patented this molecule, and what is near it?

Look up a compound by name or SMILES. Exact mode matches CAS registry numbers inside granted USPTO claim text. Fuzzy mode enumerates analogs from a core plus R-groups and reports patent coverage for each.

Before you use this tool

PatentDistance molecule search is a data-matching utility only. It is not legal advice. It does not replace a professional freedom-to-operate search by a qualified patent attorney. Open-source and public databases do not contain every patent document, and this tool assumes zero liability for false negatives - claims it does not show may still exist. Nothing here supports a legal conclusion.

Examples: aspirin · atorvastatin · metformin · imatinib

Resolved: SMILES CC(=C)C(=O)OCC(COC1=CC=C(C=C1)C(C)(C)C2=CC=C(C=C2)OCC(COC(=O)C(=C)C)O)O · 17,688 public-index patent references. Corpus match pulled from week ipg060103 of the USPTO grant feed.

What the two modes answer

Exact match

Resolves your compound to CAS registry numbers and checks which granted US patents in our corpus mention them in claims or description. This is the "who claimed this exact molecule" question, answered from our own weekly USPTO parse.

Fuzzy analogs

Enumerates concrete analogs from a core plus R-groups you supply, then reports patent coverage per analog from public patent-compound indexes. The "is this whole family taken" question, at screening depth.

Data-matching utility only. Not legal advice. Molecule search does not replace a professional freedom-to-operate (FTO) search by a qualified patent attorney. Public and open-source databases do not index every patent; we assume zero liability for false negatives. A missed result here can still be an active, asserted claim.
