01
We map the language of invention.
Our database links the many ways inventors and examiners describe the same feature — synonyms, paraphrases, and structural variants — across the patent record.
Find the prior art other searches miss.
Everyone else builds a smarter searcher. We built a smarter database — one that already links the many ways inventors describe the same idea. Pertinent references surface even when the wording does not match, without the slow hunt for synonyms.

Example
The same invention, described a dozen ways.
A keyword search finds only the words you typed
wireless earbud
the same thing, in patent language
Lambeth IP also finds every way it is described

Four more references a keyword search would miss — and each one is mapped back to the claim and the source passage, so you can open and verify it.

How it works
A smarter database, not a smarter search.
Searches miss prior art because the same invention gets described in different words. We solved that on the data side, so the search itself does not have to be clever.
02
Your question meets the map.
We scope the exact claim, feature, or product question. The database surfaces pertinent references even when their wording differs from yours — no synonym guessing.
03
Every result is verifiable.
Each reference maps back to the claim limitation and the exact source passage, so your counsel can open and check it instead of trusting a score.
Services
One database. Every prior-art decision.
Choose the path by the decision you need to support. Each engagement starts with a defined patent question and returns mapped, verifiable evidence.
Patentability / novelty
Prior art for invention and filing decisions, mapped to claim language and supporting passages.
Validity / invalidity
Issued-claim review that finds chartable references and the precise passages or figures that matter.
Freedom-to-operate (FTO)
Map products and features to the claims and references that bear on a clearance decision.
Landscape
Family-deduplicated review with citation context and classification-gap analysis.
White-space
Separate crowded claim territory from areas that may deserve a business and counsel look.
Monitoring
Recurring watch by assignee, firm, attorney, examiner, art unit, status, and family relationship.
Search report enhancement
Bring an existing search firm's static report. We add the linked, verifiable evidence layer on top — your relationships stay, the evidence becomes inspectable.
Why Lambeth IP
Why a simple search beats a clever one.
The difference is where the intelligence lives — in the query, or in the data.
Traditional search
Depends on the searcher chaining synonyms by hand. Variants get missed, and the output is a static list you cannot interrogate.
Legacy AI platforms
Return an opaque relevance score. You cannot see why a result is there, and hallucinated matches slip through unchecked.
Lambeth IP
The database already links the variants, so pertinent references surface — and every one maps to the claim limitation and source passage, so you verify instead of trust.
Confidentiality
Built for confidential work.
Strict NDA & confidentiality
Materials are handled under NDA, scoped to the engagement.
Data isolation by design
Your data is segregated; nothing is pooled across clients.
US-based infrastructure
Processing stays on US-based systems.
No third-party AI training
Your data is never used to train third-party AI models.
Not a law firm
We provide patent technology and structured evidence. Legal opinions, filing, and clearance stay with your counsel.
Questions, answered plainly.
Who is Lambeth IP for?
Patent attorneys, corporate IP teams, search firms, and inventors who need pertinent, verifiable prior art for high-stakes decisions.
How is this different from a normal search?
Most searches depend on matching keywords to the inventor's words. Our database links the many ways an invention is described, so the references surface even when the wording differs.
Can you work with our existing search firm?
Yes. Bring a static report and we add the linked, verifiable evidence layer on top, without disturbing your established relationships.
How do you guard against AI hallucination?
Every reference maps to a verbatim passage you can open in the source document. Nothing rests on an unverifiable summary.
Do you use our data to train AI models?
No. Confidential materials are handled under NDA, with data isolation by design and US-based infrastructure.
Do you provide legal advice?
No. Lambeth IP is a patent technology service. Legal opinions, filing strategy, and clearance decisions stay with qualified counsel.
Start with a high-level scope.
Send the decision you need to support and the inputs available. We follow up on scope, protections, and terms before any sensitive material is exchanged.
