Not sure which way in? Five questions, an honest answer →What else ClaimHit asks of a patent.
The same claim decomposition, the same evidence discipline, pointed at a different corpus. Each is a mode of the same search, not a separate product to learn.
Is it standard-essential?
Claims mapped to the mandatory clauses of the published specification, read out of 3GPP, IEEE, ETSI, ITU-T and IETF rather than a summary of them.
Standards Essential Patents →Claims you have not published
Paste the claim set you are prosecuting, one box per claim, or upload the application. No number needed and nothing waiting on publication.
For prosecutors →What you could claim instead
Where the claim falls short of the standard, the passage in your own specification as filed that would support reaching it, and the limitation a continuation could recite.

No setup, no learning curve. Enter a patent number and ClaimHit does the rest.

Paste your patent number from the US, EP, WO or any major office. We fetch the full claims automatically from official databases.
Sweep every relevant source
Several models propose candidates in parallel, alongside live web and neural search, forward citations, and the registries that fit your field. Every candidate is then cross-checked against real evidence, usually in a couple of minutes.

What clients say
I chose a recently granted patent having relatively complex subject matter that we already knew could be read on various GPU products. ClaimHit quickly found the expected relevant companies and products. I then requested it to generate charts. After several minutes, the tool yielded serviceable claim charts.
After testing it on a few patents, I found it surprisingly useful for uncovering relevant products I might not have thought to search for on my own.
My colleague and I have reviewed the retrieved products and the output claim charts, and we can confirm that they fully meet our technical requirements.
Thank you for the trial! Very nice software.
The work on ClaimHit was smooth and good.
