# ClaimHit

> See which companies use, or infringe, your patent. Every hit with public evidence you can open, and a Hit Chart on the strongest one.

ClaimHit is a patent-to-market intelligence service from ClaimHit LLC. A user enters a patent number; ClaimHit finds the products and standards the patent reaches, checks each candidate against public evidence the user can open, and produces a Hit Chart that maps every element of a claim to that evidence. Results are preliminary research, not a legal determination.

## Ways to start

- Prices are published at https://claimhit.com/pricing. One price covers a patent: the search that finds the products it reaches, and the Hit Charts that map a claim onto them. Three packages — Essential $199 for 1 search and 2 charts, Professional $799 for 5 searches and 10 charts, Portfolio $2,999 for 20 searches and 40 charts — or build your own at $119 a search and $40 a chart, on the same volume terms. There is no subscription and credits never expire.
- Pilot: a first patent at $99, the same one search and two Hit Charts as the Essential package at half the standing price, once per account, with a 30-day money-back guarantee. https://claimhit.com/pricing
- More than 99 patents, a subscription, or an API integration: a conversation rather than a package. https://claimhit.com/contact
- Expert Review: an attorney with subject-matter expertise finishes a Hit Chart — closes the limitations the engine could not close from public sources, verifies every citation against its document, corrects the technical reading, and states what cannot be established and why. Flat for a review of a search's target list, per chart for chart reviews; payment upfront, delivered in 36 hours. Scope decides the rate, so it is quoted by a person rather than listed. The report is research to support a decision: not a formal infringement opinion, not a freedom-to-operate clearance, and not legal advice. https://claimhit.com/expert-review
- Machine interfaces: ClaimHit speaks the Model Context Protocol at https://app.claimhit.com/api/mcp, with OAuth 2.0 and seven tools, so a patent search runs from inside Claude and the result can be narrowed, filtered, sorted and paged there without spending a credit; the two tools that spend a credit quote the cost and wait to be confirmed. The same engine answers over REST at https://app.claimhit.com/api/v1 — OpenAPI 3.1, bearer keys, sandbox keys that serve fixtures and are never charged, 20 requests a minute. An assessment is asynchronous: POST a patent, poll the id or give a callback_url, and act on it when the status says COMPLETE. A patent may be sent as a publication number, as claim text, or both. API access is arranged with a person rather than self-serve. https://claimhit.com/integrations
- We run it for you: send a list of patents and ClaimHit replies with a proposal within 24 hours on a business day, then runs the list on your go-ahead. Results are paid for, starting with the pilot; proposals are free. https://claimhit.com/#run-for-you

## Blog posts
- Should You Pay the Renewal Fee? Ask Who Is Practising the Patent First (2026-10-12): https://claimhit.com/blog/renewal-fee-decision: Renewal decisions get made on budget and gut feel, because the one input that would settle them — whether anyone is actually practising the patent — is the one nobody has. Here is how the deadlines work, why the costs are asymmetric, and what evidence changes the answer.
- How ClaimHit Verifies Infringement Candidates (2026-04-02): https://claimhit.com/blog/hit-score-methodology: ClaimHit does not rely on a single model's opinion. Multiple models propose candidates in parallel, and every candidate is then cross-checked against live web evidence before it reaches you. Understanding that pipeline changes how you read the results.
- What Is a Standards Essential Patent, and How Do You Find If Yours Is One? (2026-03-28): https://claimhit.com/blog/sep-analysis-explained: If your patent covers a mandatory requirement in a published technical standard, every company implementing that standard may owe you a licence. Here is how SEP analysis actually works.

## Frequently asked
- Q: How accurate are the results?
  A: ClaimHit does not rely on a single model's opinion. Several models propose candidates in parallel, and every candidate is then cross-checked against live web evidence. Only a product confirmed on public sources reaches your results, with those sources listed so you can open them yourself. Anything that could not be confirmed is dropped rather than shown with a caveat. Every result is a lead worth investigating; none is a determination of infringement.
- Q: Which patents and offices are supported?
  A: US (USPTO), European (EPO), WIPO PCT, and most national offices via Espacenet. Enter any standard format, such as US10123456B2, EP1234567B1, WO2020123456A1. Japanese, Korean, and Chinese patents are supported via EPO translation.
- Q: What is the difference between a ClaimHit search and Expert Review?
  A: A search is the machine's half and it is fast and broad: several models propose candidates, every one is cross-checked against live web evidence, and a Hit Chart maps the claim element by element with each source a link you can open. It also names the limitations it could not close from public sources — that is the honest end of what software does alone. Expert Review is the second step: an attorney with subject-matter expertise closes those limitations against source documents, verifies every citation against the document it came from, corrects the technical reading where the engine mapped a claim term onto the wrong mechanism, and states plainly what cannot be established and why. Flat for a review of a search's target list, per chart for chart reviews, payment upfront, delivered in 36 hours; the rate is shown before you pay. Use the search to decide internally whether a target is worth pursuing; buy the review when you are going to send it to somebody.
- Q: Who does the Expert Review, and what is the report?
  A: An attorney with subject-matter expertise in the technology the patent is about — somebody who can read a manufacturer's documentation the way an engineer reads it and knows what a claim element has to be matched against. That combination is deliberate: what an AI chart gets wrong is usually the technical reading of a real product, and what makes the result usable is somebody qualified putting their name to it.

What comes back is a verified, element-by-element mapping of the claim onto a real product, with its evidence, signed. It is research to support your decision — not a formal infringement opinion, not a freedom-to-operate clearance, and not legal advice to you. Ordering it does not create an attorney-client relationship, and whether to issue a reasoned opinion is a separate engagement you would take up with counsel. The report says all of this in those words.
- Q: What if a limitation cannot be closed?
  A: The report says so, and why — what would settle it and where that document would have to come from. That is a finding rather than a failure: knowing a gap is real, and what it would take to close it, is what stops a licensing letter going out on an assumption. You get the full report either way; the review is paid for the work of establishing the answer, not for the answer being yes.
- Q: What does a result mean?
  A: A result is a company and product that survived the full pipeline: proposed by several models, checked by live web search, filtered for noise and category, and confirmed on the manufacturer's own page. It is listed with the pages, datasheets or filings that confirmed it. Open the sources first; a result you have read is a lead, a result you have only looked at is a name.
- Q: Why doesn't ClaimHit claim infringement?
  A: Because infringement is a legal conclusion, not a research output. ClaimHit surfaces candidates that may infringe: products and standards worth investigating, each cross-verified against live web evidence. Determining whether infringement actually exists requires a qualified patent attorney and formal claim construction. Expert Review does not change that: it is research prepared by an attorney with subject-matter expertise, not a formal infringement opinion. Our role is to make that investigation faster, not to replace it.
- Q: How does ClaimHit use AI models?
  A: Several frontier models from different providers run in parallel against your patent's inventive contribution. Each independently proposes candidate products and companies. This is the discovery step, not the final answer. Using models from different providers matters: they have different training data and failure modes, so a candidate several of them surface independently is less likely to be one model's hallucination. Every candidate is then cross-checked against live web evidence and confirmed on manufacturer pages before it reaches you. Models propose; evidence decides.
- Q: Is my patent data kept confidential?
  A: Yes. Your searches are used only to generate your results and are never sold or used to train AI models. Patent numbers are public records. We treat any additional context you provide as confidential.
- Q: What is SEP and FRAND analysis?
  A: Standards Essential Patent analysis checks whether your patent covers mandatory features in technical standards like Wi-Fi 6, 5G NR, or HEVC. SEP holders can demand FRAND (fair, reasonable, non-discriminatory) licensing from any implementer of the standard. ClaimHit maps your claims to published specifications from 3GPP, IEEE, ETSI, ITU-T, and IETF.
- Q: What is the pilot?
  A: One patent: the full product search and one Hit Chart, for a fixed price shown on the homepage, with a 30-day money-back guarantee. Once per account, no subscription, no card on file after that. It is the fastest way to judge ClaimHit on a patent you know inside out.
- Q: How do I get more searches or Hit Charts?
  A: Ask for a credit pack from the Credits page in your account or through the contact page. Tell us how many product searches and Hit Charts you need and we reply with a proposal within 24 hours on a business day. Credits never expire.
- Q: Can you run my patents for me?
  A: Yes. Paste the list on the homepage form. We reply with a proposal for the whole list within 24 hours on a business day and run it on your go-ahead: the Hit Matrix across the portfolio, claim charts on the strongest hits, and the campaign briefs. No software to learn.
- Q: How long does a search take?
  A: A few minutes for the search, and a few more for a Hit Chart on the strongest hit. Results arrive on screen and by email.
- Q: What is a Hit Chart?
  A: A claim chart built element by element. The claim is broken into its limitations, and each is judged FULL, PARTIAL or NONE against a quotable excerpt from public evidence: a datasheet, a manual, a filing, a standard. A rating only survives if a real excerpt supports it. Nothing is rounded up.
- Q: What is the Hit Matrix?
  A: When you run a portfolio, the results come back as one grid: patents along the top, companies down the side, a filled cell where a patent reaches one of that company's products. The companies that keep appearing across patents are where a licensing conversation starts. The grid exports to Excel.
- Q: What is the patent watch?
  A: A standing watch on one patent. Give us a patent number and a work email, confirm the address, and we read the companies whose products reach the patent, look again every quarter, and email you how many new ones appeared. The names and the sources are the Hit Report, which the pilot runs on any patent. One patent per address, one click to stop.
