Business problems
Where teams get stuck.
01
Prior-art searches that miss non-patent literature and lose invalidity arguments at trial.
02
Freedom-to-operate opinions that arrive too late to inform product launch decisions.
03
Offshore search vendors delivering keyword-only results without technical interpretation.
04
Inconsistent search quality across jurisdictions and technology domains.
Our solution
Expert analysts, AI retrieval, defensible evidence.
Every Hashi search is led by a domain-expert analyst — a PhD, engineer, or registered agent — supported by our AI retrieval stack. We combine semantic search, citation graphs, and classification-aware queries across patent databases, journals, standards, and grey literature. The result: search reports that hold up under prosecution, litigation, and board scrutiny.
- PhD- and engineer-led search teams organised by technology domain.
- AI-augmented semantic + citation retrieval across 140M+ records.
- Non-patent literature: journals, standards, whitepapers, product manuals, GitHub, arXiv.
- Two-tier peer review with signed analyst attribution on every report.
- Delivered in editable Excel, PDF, or via API into your IP management platform.

FAQ
Questions our clients ask most often.
How is Hashi search different from a database subscription?+
Databases return hits; Hashi returns evidence. Every report is scoped, executed, and interpreted by a domain-expert analyst — with peer review — so you receive a decision-ready assessment, not a list.
What is your typical turnaround?+
Standard turnaround is 72 hours for novelty and prior-art searches, 5–10 business days for invalidity and FTO. Expedited 24-hour delivery is available for most search types.
Do you cover non-patent literature?+
Yes. Every Hashi search includes journals, conference proceedings, standards, product manuals, GitHub, arXiv, and industry whitepapers. NPL is often decisive in invalidity work.
Which jurisdictions do you cover?+
All major PTOs — US, EP, JP, CN, KR, IN, DE, GB, FR, AU, CA and 30+ additional jurisdictions. Native-language analysts handle JP, KR, CN, DE, and FR references.
Do you sign NDAs and handle privileged work?+
Yes. Hashi routinely operates under NDA, common-interest, and attorney-client privilege, with private-tenancy AI options for sensitive work.
