When a patent stands in your way,
find the art that takes it down.
An AI invalidity search engine that builds claim-chart-ready prior art for IPR, opposition, and litigation defense, across 295M+ patents, papers, and clinical trials.
Invalidity search is the offensive twin of prior-art search. Where prior art protects your own claim, invalidity attacks someone else's. The job: build a defensible record of anticipating art against a granted patent, formatted for an IPR petition, EPO opposition, or invalidity counter-claim. Kwintely searches by claim element, not just by topic, and produces the claim-by-claim mapping that counsel needs.
Litigation hits Tuesday. The asserted patent has six independent claims. Counsel needs invalidity art for each, within 30 days for the IPR petition, sooner if you want to pre-position the response. The associate team is two weeks deep in Boolean Espacenet searches. The hearing is in eight weeks.

What teams ask before they sign.
Will counsel use this for an IPR petition or opposition?
Yes, Kwintely produces the structured claim chart and exhibit set that counsel would otherwise spend significant associate time generating. Counsel keeps ownership of the legal arguments and final brief; Kwintely handles the search and evidence mapping. Each result includes the source document, publication date, and the relevant passage quoted verbatim, exactly the form an IPR petition requires.
Is the output ready for counsel review?
Every result includes the source document, publication date, similarity score, and the relevant passage quoted verbatim. The output is structured the way an associate-led search would be: ranked, cited, exportable. The AI is a mapping engine; the documents it surfaces are real. Counsel still makes the legal call; Kwintely does the search and citation prep.
How does this fit with my existing patent firm?
Most teams run Kwintely before engaging counsel, to scope the work and narrow the candidate set, then walk into the review with the search prep already done. Counsel spends their hours on judgement and the legal opinion, not on assembling the candidate list.
What about pricing and lock-in?
Three ways to work with Kwintely: the self-serve SaaS platform, scoped research-service projects where our team runs the analysis for you, or the API and MCP data layer for your own tools. Full output runs on a paid plan, the free tier is for trying basic searches, not complete deliverables. See the pricing page for current plans and terms.
Run the experiment, not the procurement.

Counsel still signs off
Kwintely produces the structured search; your firm keeps ownership of the legal opinion. Nothing about your existing relationship has to change.
Run it on a real case
Pick the technology you'd already pay counsel to clear. Compare what Kwintely returns against what your firm would charge for. Decide on the second case, not the first.
No lock-in
Free tier covers the first basic experiment. Full output on paid plans. Fixed monthly fee on the way up. The cost of the test is one search.
