ClaimWatch is a weekly agent over the official patent feeds. It maintains a living dossier for every competitor and claim space you watch — and tells you what changed, with a link back to the exact claim and filing date.
The trust standard
If we can't point to the claim, the document, and the date — we don't put it in your brief.
Patent monitoring is the rare research domain where the ground truth is a free, canonical, permanently archived government record. ClaimWatch is built around that fact: extraction is grounded and claim diffs are computed deterministically — never invented by a model.
Every sentence in a dossier or brief resolves to a stored document ID and claim number, and is validated after generation. No source, no claim.
Amendments are computed as exact text diffs against the canonical file wrapper — not paraphrased. The redline is the record, not a guess.
The dossier grows every Tuesday and Thursday. You don't get a one-off snapshot — you get the whole prosecution arc, kept current.
What ClaimWatch does
Define what you care about as CPC classes, named competitors and inventors, and a plain-language description of your claim space. The agent does the reading.
Combine CPC classes, named competitors, and inventors with a natural-language description of the territory you're defending. ClaimWatch screens every new publication against it.
The radar flags new filings in your space, claim amendments during prosecution, ownership changes, and fee lapses or expirations — each tagged, dated, and linked.
The weekly brief reasons over prosecution history, not just headlines: "Competitor X's continuation narrowed claim 1 after a rejection — this opens design space in Y." Every step of the reasoning links back to the office action and claim it rests on, so your counsel can review it, not just trust it.
Grants publish Tuesday, pre-grant applications Thursday. ClaimWatch ingests the bulk feeds on the same rhythm — so the brief is never stale and never noisy.
The brief is the primary touchpoint — readable enough to forward to a board, structured enough to drop into a client file. The Counsel tier adds a PDF export formatted for outside counsel; the Firm tier white-labels it per client workspace. It's monitoring work made reviewable, not another inbox of keyword-alert spam.
How it works
USPTO full-text and assignment data, EPO OPS, WIPO PATENTSCOPE, and litigation dockets — refreshed on the Tuesday/Thursday publication cycle. Cheap-model screening narrows hundreds of new documents to what touches your watchlist.
A frontier pass updates each family's claim-evolution timeline, assignment history, and prosecution status. Claim diffs are computed deterministically from the canonical text — never written by the model.
You get a synthesized brief over email and on the web: what changed, why it matters for your claim space, and a verifiable link for every assertion. Forward it, file it, or hand it to counsel for review.

Questions
No. ClaimWatch is a monitoring and research tool. It surfaces filings, computes claim diffs, and explains what an amendment could mean for a claim space — but a freedom-to-operate or patentability opinion is a legal judgment that only a qualified attorney can give.
That's why the brief is built to be reviewed: every assertion links to the underlying document so your in-house or outside counsel can check it and decide. ClaimWatch makes their monitoring work faster and reviewable; it does not replace their opinion.
Two parts behave very differently. Extraction and claim diffs are computed deterministically from the canonical record, so a cited amendment, claim number, and date are mechanically verifiable. We treat that as the trust floor of the product.
Recall is harder and we won't overclaim it. Matching a natural-language claim space against deliberately broad patent language, divisionals filed under unexpected CPC codes, or jurisdictions we don't yet cover means some filings can be missed. ClaimWatch is a powerful early-warning layer, not a guarantee of completeness — pair it with counsel for anything diligence-critical.
Free, canonical government sources: USPTO full-text, assignment, and file-wrapper data; EPO OPS; WIPO PATENTSCOPE; and litigation dockets via court records. The corpus is structured and openly published, which is exactly why ClaimWatch can offer synthesis at a fraction of the incumbent price.
Because the data publishes weekly. Patent grants come out Tuesdays and pre-grant applications Thursdays, and prosecution moves over months and years — not minutes. A weekly brief matches the real rhythm of the corpus and produces a synthesized, forwardable document instead of a stream of low-signal pings.
