ClaimHit / Who it's for / Patent Prosecutors
Prosecute toward claims that still read
An amendment that narrows past the market wins allowance and loses the value. ClaimHit maps the claims you are prosecuting against real products, and, for standards work, against the specification itself, so you can see where today’s language actually lands before you decide how to narrow it. Where a limitation falls short it goes one step further: it looks in your own specification as filed for wording that would reach, and drafts it. The claims do not have to be published — paste them, or upload the draft.
A narrowing amendment can sail through the office and quietly walk the claim off every product that mattered, and nothing in the file tells you it happened.
The claims that matter most are the ones not yet published, so there is nothing to look up. A tool that works from a patent number cannot see the language you are actually arguing about.
Whether a limitation still reads on shipping products is a market question, answered by hand if at all, under an Office Action clock.
For SEP work an amendment has to track what the standard actually mandates, and the specification is thousands of pages you were not going to re-read for one response.
What ClaimHit does about it
Unpublished claims, pasted in
Type the claim set you are prosecuting, one box per claim, or upload the application and let the fields fill themselves. No number needed and nothing waiting on publication, and the language you typed is what every stage reasons from rather than a granted claim that no longer matches your file.
Where the claims land today
See which real products the current claims read on, element by element, each match backed by a citable source. The map you amend against, not a guess about the market.
Against the standard itself
For SEP prosecution, claims are mapped to the mandatory provisions of the technical standard, read from the specification text of 3GPP, ETSI, IEEE and ITU rather than a summary, so an Office Action response can track what the standard actually requires.
Which limitation carries the reading
The claim is decomposed into individual elements, each judged on its own evidence, so you can see exactly which limitation is doing the work, and which one a proposed amendment would put at risk.
Wording your specification already supports
Where a limitation falls short, the engine reads your own specification as filed for a passage describing what the product or the standard actually does, and drafts language from it. Every substantive word is traceable to that passage, and the passage is quoted beside it with its locator.
An honest NONE
Where the public record does not support a limitation it is reported NONE, never rounded up, so the map you steer amendments by reflects the evidence rather than optimism.
Where the claim falls short, what you could have claimed instead.
A standards chart names the requirements your claim does not reach. On that chart ClaimHit will go looking, in your specification as filed, for passages that describe those requirements in terms — and draft the limitation a continuation could recite. The chart is the input, so there is nothing new to set up.
What a new claim could recite
The proposed limitation, drafted only where the specification describes the requirement in terms. Every substantive word of it traces to the passage in the next column.
Support in your specification
That passage, verbatim, with its locator. Read right to left the worksheet is how the wording was arrived at; read left to right it is the case for filing it.
What the standard requires
The clause the limitation is aimed at, in the standard’s own words. The three belong on one row, which is why the deliverable is a table you can take to a filing meeting.
A beautifully supported amendment that cannot lawfully be filed is a more expensive mistake than a run that stops early, so these are arithmetic on the record before a single model is called.
- Co-pendency. A continuation can only be filed while something in the family is still pending. Where the continuity data does not say, that is printed as a caution rather than assumed open.
- Prior art. A release that froze before your earliest priority date is prior art to the patent. Drafting a claim onto it is drafting over published text the examiner also holds, so it is excluded as a target.
- Term. A continuation issues with the parent’s term. Never a blocker — a short patent can still be worth filing — but it is your commercial call, so it is shown rather than decided for you.
Every result has to earn it. Candidates come from several models, live web search, forward citations and the registries for the field, but breadth only widens the net. Each one is still checked against real, citable evidence. See how →
