Verify certificate of authenticity for a Mark

Every claimed Mark carries a numbered certificate in its holder's name. Anyone can check one in seconds, without an account, and read exactly who holds the Mark and how it got there.

The short version

  • Anyone can verify a Gradiently certificate at gradiently.design/verify by entering its number, such as GRC-7K2M-9QXA-4TPW, or the Mark's code.
  • Checking a certificate needs no account and no sign-in.
  • The result says whether the certificate is current, replaced by a newer one, no longer current, or revoked, then shows the holder and the Mark's full history.
  • Each change of owner issues a new certificate and replaces the old one, so an older certificate stays genuine as a record but no longer proves who holds the Mark today.
  • A certificate is a Gradiently registry record: it is not an NFT, uses no blockchain and is not a registered trademark.

When you would verify a certificateHow to verify a certificate, step by stepWhat the four verdicts meanWhat a certificate showsWhat a certificate proves, and what it doesn'tKeeping your own certificate to hand

To verify certificate of authenticity for a Gradiently Mark, go to gradiently.design/verify, type the certificate number from the top of the certificate (it reads like GRC-7K2M-9QXA-4TPW) or the Mark's code, and choose Check. You need no account. The answer comes straight from the Gradiently registry, the only place certificates are issued: whether the certificate is genuine and current, who holds the Mark today and since when, and every change of hands since it was made.

This page is a practical walkthrough of that check and how to read the result. For what codes and certificates are in the first place, see Mark codes and certificates.

When you would verify a certificate

  • A client taking over from an agency wants proof the Mark their brand runs on is now in their name, not the agency's.
  • Someone about to claim a Mark listed on the Market wants to see its history before relying on it.
  • A business recording its brand assets keeps the certificate number in its style guide and checks it each year.
  • Anyone shown a design who wants to know whether its look genuinely belongs to the brand using it.

How to verify a certificate, step by step

  1. 1

    Find the number

    It sits at the top of the certificate. If you only have the Mark's code, such as GR·K7Q2·MX, that works too.

  2. 2

    Open the verify page

    Go to gradiently.design/verify. You can also reach a Mark's certificate from Certificate of authenticity in its Details.

  3. 3

    Type it and choose Check

    Certificate numbers start with GRC and have three groups of four characters. If the format is wrong, the page tells you before it searches.

  4. 4

    Read the verdict first

    The sentence at the top says whether this certificate is current. Everything below it is evidence for that sentence.

  5. 5

    Then read the history

    Every event, with dates, from the Mark's creation to its current holder.

text
Certificate number   GRC-7K2M-9QXA-4TPW   one owner's time with one Mark
Mark code            GR·K7Q2·MX           the Mark itself, never changes
Code, typed loosely  grk7q2mx             also accepted: no dots, any case
Two things you can type into the verify page. The certificate number identifies one holding; the code identifies the Mark.

If nothing matches, the page says no certificate has that number. Check each character against the original: a mistyped group is the usual cause. If you entered a Mark's code and nobody has claimed it yet, the page says the Mark has no certificate yet, because the first person to claim it receives the first one.

What the four verdicts mean

Authentic and current

What it tells you

An original Gradiently Mark, held by the named person since the date shown. This is its live certificate.

What to do

Nothing. This is the proof you were looking for.
Authentic, but replaced

What it tells you

The certificate was genuine when issued, but the Mark has a new owner, named on the page.

What to do

Follow the link to the current certificate.
Authentic, no longer current

What it tells you

Genuine when issued, but that holder no longer holds the Mark.

What to do

Check the history for what happened next.
Revoked

What it tells you

The Mark was removed from the Gradiently registry.

What to do

The certificate no longer proves anything about the Mark.

RevokedThe Mark was removed from the Gradiently registry.The certificate no longer proves anything about the Mark.
A certificate belongs to one owner's time with a Mark. Each change of owner issues a new one and replaces the old.

The replaced and no longer current verdicts are not warnings of fraud. They are how the record stays honest: an old certificate is still a true statement about the past, it just isn't proof of the present. Anyone about to claim a listed Mark, or a client taking one over, should want to see Authentic and current.

FingerprintThe registry's SHA-256 fingerprint of the Mark's artwork
Every field comes from the registry. Nothing on the certificate is typed in by its holder.

The fingerprint deserves a word. SHA-256 is a standard way of turning data into a fixed string of characters: change anything in the input and the string changes completely. The registry fingerprints the Mark's artwork, so the fingerprint ties the certificate to one exact recipe. You can copy it from the certificate if you want to record it alongside the number.

Reading the history

Below the facts is the Mark's history, oldest first. The events you'll see are Created by, Claimed by, Claimed on the Market by, Transferred to and Returned to Gradiently. A Mark that an agency claimed and then gave to its client reads as created, claimed by the agency, then transferred to the client, with the client's certificate marked current and the agency's replaced. A Mark that went unkept reads as returned to Gradiently before its next claim.

What a certificate proves, and what it doesn't

It proves

  • The Mark is an original Gradiently Mark
  • Who holds it on Gradiently, and since when
  • Every change of hands, as the registry recorded it
  • That only the holder can export designs with it

It is not

  • A registered trademark or any legal title outside Gradiently
  • An NFT, a token or anything on a blockchain
  • Proof about colours in general: it covers one recipe, not a hue
  • A record anyone other than the registry can issue

If you need legal protection for a brand's look, speak to a trademark professional in your country. The certificate gives you something simpler and immediate: a public record anyone can check. Marks compared with NFTs and digital ownership certificates go further into the difference.

Keeping your own certificate to hand

From any certificate you can copy its number, copy a link to it, open the Mark, or choose Download certificate for a PDF copy. A good habit is to put the Mark's code and the current certificate number in your brand style guide, so a new designer, a printer or a client can check the look in seconds. When the Mark changes hands, through a transfer or a claim on the Market, update the number: the old one will still verify, but as replaced.

Questions people ask

How do I verify a Gradiently certificate?

Go to gradiently.design/verify, enter the certificate number (like GRC-7K2M-9QXA-4TPW) or the Mark's code, and choose Check. No account is needed.

What does it mean if a certificate has changed hands?

The certificate was genuine when issued, but the Mark now has a new owner with a newer certificate. The page links to the current one.

Why does a Mark have no certificate?

Nobody has claimed it yet. The first person to claim a Mark receives its first certificate, in their name.

What is the fingerprint on a certificate?

It is the registry's SHA-256 fingerprint of the Mark's artwork, which ties the certificate to one exact recipe.

Is a Gradiently certificate a trademark or an NFT?

Neither. It is a record in the Gradiently registry, with no blockchain, and it is not a registered trademark.
