DNA / sequence search
Find patents that carry a resembling sequence from a DNA/RNA nucleotide or protein amino-acid sequence. Search by sequence alone, or add a topic to narrow by use. In biotech, pharma, and agri-bio prior-art work, a sequence is a far more precise identifier than any keyword.
A real search
Real results from searching with the human insulin precursor (preproinsulin, 110 aa) sequence.
① By sequence alone
Input (sequence only)
"Find patents that contain this protein sequence: MALWMRLLPLLALLALWGPDPAAAFVNQHLCGSHLVEALYLVCGERGFFYTPKTRREAEDLQVGQVELGGGPGAGSLQPLALEGSLQKRGIVEQCCTSICSLYQLENYCN"
Paste the raw sequence as-is — spaces are ignored and DNA/RNA/protein is detected for you. Patents carrying the sequence come back regardless of purpose.
| Result | Title | Nature |
|---|---|---|
| US11576876B2 | Affinity Medicant Conjugate | Conjugate |
| US20220106378A1 | T-cell modulatory antigen-presenting polypeptides | Polypeptide |
| CN108414766A | Kit for quantitatively detecting diabetes autoantibody | Diagnostic kit |
② By sequence + topic
Add a topic alongside the same sequence, and FindIP re-ranks the sequence matches by use. You can write the sequence and the topic in one sentence — the AI splits them for you.
Input (sequence + topic)
"Find patents similar to this sequence that concern long-acting insulin analog formulations: MALWMRLLPLLALLALWGPDPAAAFVNQHLCGSHLVEALYLVCGERGFFYTPKTRREAEDLQVGQVELGGGPGAGSLQPLALEGSLQKRGIVEQCCTSICSLYQLENYCN"
Now it narrows to genuine insulin-analog therapeutics.
| Result | Title | Country |
|---|---|---|
| JP2021168687A | Novel insulin analogs and use thereof | JP |
| KR1020130043085A | Long-acting insulin analogue preparations | KR |
| CN121398841A | Treating type-1 diabetes with tolerizing nanoparticles | CN |
When to reach for it
- Prior-art and freedom-to-operate on antibody, peptide, or gene sequences
- Designing around or near a competitor's sequence patents
- Checking whether a sequence from a paper or database already appears in a patent
Coverage
Sequences are extracted from the full text of indexed patents, so they follow that coverage range (from 2001 onward, China from 2010). See Data coverage for details.
