Proof of creation vs. trademark: what a timestamp can and cannot do

By the logoBlockchain team · 9 November 2026 · 7 min read

Not legal advice. This article is general information, not legal advice, and laws differ by country. A logoblockchain registry entry is evidence that a specific file existed at a point in time. It is not a trademark or copyright registration and does not by itself establish ownership. For decisions about protecting or using a brand, talk to a qualified attorney or registered trademark professional in your jurisdiction.

“I timestamped my logo, so it’s protected, right?” Not in the way most people mean. A timestamp and a trademark answer different questions, are created by different processes, and do different jobs. This article explains, in general terms, what each one is, how copyright fits in, where a proof-of-creation record is genuinely useful, and where it is not a substitute for anything.

The short version

• A proof-of-creation record (such as a logoblockchain registry entry) is evidence that a specific file existed at or before a specific time. Anyone can create one; nobody examines it.
• A trademark is about using a sign — a name, logo, or other mark — to identify the source of goods or services. Rights generally depend on use and/or registration with a government trademark office, and they are limited to particular goods or services and territories.
• Copyright protects original creative expression, and in many countries it arises automatically when a work is created. Simple logos may not qualify at all.
• A timestamp can be evidence in a situation involving trademarks or copyright. It is never a registration of either.

What a proof-of-creation record is

When you register a file on logoblockchain, your browser computes its SHA-256 hash — a unique fingerprint of the exact bytes (see SHA-256 for designers). That fingerprint is added to a public hash chain, and the chain is timestamped on Bitcoin through OpenTimestamps. The result lets anyone later confirm that this exact file existed no later than the recorded time.

Three things are deliberately absent from that process:

• No examination. Nobody checks whether the logo is original, whether it resembles someone else’s mark, or whether the person registering it made it.
• No exclusive rights. The record does not stop anyone from doing anything. It is information, not a permission or a prohibition.
• No territory or class. It does not relate to any country or any category of goods and services.

That narrowness is a strength — the record is simple, cheap, independent, and verifiable — but it means the record has to be understood for what it is.

What a trademark is

A trademark is a sign that tells customers who is behind a product or service. A logo can be a trademark when it is used that way — on packaging, a storefront, a website, an app — so that people associate it with one business.

A few general points hold in many legal systems, though the details vary considerably by country:

• Trademarks are tied to goods and services. Registrations are typically filed for specific categories of goods and services. Two businesses in unrelated fields can sometimes use similar marks without conflict.
• Trademarks are territorial. A registration in one country generally covers that country (or region, for regional systems). International filing systems such as WIPO’s Madrid System make it easier to seek protection in several places, but protection is still granted country by country.
• Use and registration both matter, differently by country. In the United States, for example, some rights can arise from using a mark in commerce, and federal registration with the USPTO adds further benefits (the USPTO’s trademark basics explains this). Many other countries place much more weight on who files first. This difference alone is a reason to get local advice.
• Registration involves examination. Trademark offices typically examine applications against legal requirements and, in many systems, earlier marks. Others may be able to oppose an application.
• The test is usually confusion, not identical files. Disputes generally turn on whether customers are likely to be confused about who is behind a product — which depends on the marks, the goods or services, the market, and more. Whether two image files share a hash is irrelevant to that question.

Government offices publish plain-language introductions worth reading before you talk to a professional, for example the USPTO page above, the UK government’s guide on registering a trade mark, and WIPO’s overview of trademarks.

Where copyright fits

Copyright protects original works of authorship, including artwork. Under the Berne Convention, which most countries have joined, member countries may not make the enjoyment of copyright in works from other member countries conditional on formalities such as registration. In practice, in many countries copyright arises automatically when an original work is created.

Two complications are common with logos:

• Simple marks may not be protected by copyright. In the United States, for example, the Copyright Office explains that names, short phrases, and typefaces or mere variations of typographic ornamentation or lettering are not protected by copyright (Circular 33, “Works Not Protected by Copyright”). A plain wordmark may fall into that category, even though it can still work as a trademark.
• Registration can still matter procedurally. Even where copyright is automatic, some systems treat registration as important. The US Copyright Office notes that registration is generally voluntary, but that you will have to register before bringing a lawsuit for infringement of a US work (see its general FAQ).

Who owns copyright in a commissioned logo — the designer or the client — depends on the contract and the applicable law. A timestamp does not settle that either.

Side-by-side comparison

Where a timestamp genuinely helps

A proof-of-creation record is useful precisely because it is independent and hard to dispute. Situations where it can support your account (as one piece of evidence among others) include:

• Showing your design history. Timestamped drafts and finals show when each version existed, which supports a story of independent creation.
• Platform disputes. Marketplaces and social platforms often ask for evidence when two parties claim the same artwork. A verifiable date can help you explain your side.
• Client relationships. A record of when concepts were delivered can clear up disagreements about what was presented and when.
• Supporting a professional. If you do end up working with a lawyer, organised, dated evidence makes their job easier. They will decide what is relevant.

Our guide on how to prove you created a logo describes how to combine a timestamp with the other records you already have.

What a timestamp cannot do

• It cannot give you the right to stop others from using a similar logo.
• It cannot tell you whether your logo is safe to use or conflicts with an existing trademark.
• It cannot establish that you were the first to create a design — only that your file existed by a certain time.
• It cannot prove authorship on its own; it records who submitted a file, not who drew it.
• It cannot replace a trademark search, a trademark application, a copyright registration, or a contract.

The optional logoBlockchain Verified plan does not change any of this. Its seal, PDF certificate, evidence bundle, look-alike notices, and version history make the same evidence easier to present and monitor. It is not a registration and not legal protection.

A sensible order of operations

For a new brand, a practical sequence looks like this. Treat it as a checklist of questions to raise, not a legal plan:

1. Check for obvious conflicts early. Search the web, app stores, domain names, and the public trademark databases offered by the offices in the countries you care about. This is not a substitute for a professional clearance search, but it catches many problems cheaply.
2. Design and keep records. Keep sketches, drafts, and source files. Timestamp the versions that matter.
3. Sort out ownership. If someone else designed the logo, get a written agreement covering ownership or licensing of the final design.
4. Get advice before significant investment. Before printing packaging, launching a big campaign, or expanding to new countries, talk to a trademark attorney or registered trademark professional about clearance and registration.
5. Register where it makes sense. File trademark applications in the markets and for the goods or services that matter to you, on your professional’s advice.
6. Keep timestamping new versions. Brands evolve. A record for each version keeps your history complete.

™ and ®

In many countries, the ® symbol is reserved for marks that are actually registered, and using it for an unregistered mark can be unlawful. The ™ symbol is commonly used to signal that you claim a mark as yours without implying registration. Rules differ by country, so check locally before putting either symbol on products. A proof-of-creation record never entitles you to use ®.

Used honestly, a timestamp is a small, useful habit: it turns “I had this design back then” from a claim into something anyone can check. It just isn’t a trademark — and it should never be described as one.

Reminder: general information only, not legal advice. A registry entry is proof that a file existed at a time, not trademark or copyright registration.
