How to Prove a Logo Design Was Yours

Why Most Designers Cannot Prove Logo Ownership When It Counts

You deliver a final logo, the client relationship turns sour, and they claim they commissioned the work and therefore own it outright. You have the Figma link, the invoice, and a clear memory of every revision cycle. None of that is enough on its own — and that is the position most designers find themselves in.

The records designers usually reach for feel solid until someone challenges them. Local file creation dates can be altered. An invoice shows you were paid for something, not that you created the specific artwork in dispute. Email threads without attached files show a conversation happened, not what the file contained at that moment. These records are not worthless, but they rarely stand on their own.

• Local file dates — changed by copying, re-saving, or moving between drives
• Invoices — evidence of payment, not of authorship
• Email threads without attachments — evidence of a conversation, not of a file
• Screenshots — easy to produce after the fact, so easy to question

The Only Window That Produces Strong Proof

What matters in an authorship dispute is evidence that is externally dated, hard to alter, and tied to the specific file in question. The question opposing counsel will ask is simple: could you have created or modified these records after the dispute started? If the answer is yes, the evidence is weak.

That is why the pre-delivery phase matters so much. Once a dispute is active, draft files with untouched timestamps, contemporaneous emails with attached versions, and an ordered revision history either do not exist or look assembled. The time to collect evidence is before any file reaches the client.

What Evidence Actually Helps

The strongest single piece of evidence is a U.S. Copyright Office registration. Registration made before or within five years of publication constitutes prima facie evidence of the validity of the copyright under 17 U.S.C. § 410(c). Under § 412, statutory damages and attorney's fees are generally available only where registration precedes the infringement, or is made within three months of first publication. Without timely registration, recovery is limited to actual damages, which are harder to quantify for a logo.

Your editable source files are the strongest non-registered proof. A layered AI, PSD, or Figma file with visible revision history, layer names showing development stages, and embedded author metadata tells a different story than a flat exported PNG — it shows the process, not just the result. Someone who copied the finished mark usually cannot produce one.

• Copyright registration — strongest, and unlocks remedies nothing else does
• Layered source files — show development, not just the outcome
• Third-party timestamps — dated outside your control, so harder to dismiss
• Cloud version history — useful, but depends on account access and platform policy
• Email with the actual file attached — corroboration, and far stronger than an approval reply

Seal Every Draft Before It Leaves Your Device

A cryptographic fingerprint is a unique value derived from the exact binary contents of a file. Hash functions in the SHA-2 family, including SHA-384, are designed so that changing a single pixel produces an entirely different fingerprint. An RFC 3161 trusted timestamp anchors that fingerprint to a date and time attested by an independent Time Stamping Authority, producing a signed record that a specific version of your file existed at a specific moment.

CREATORSEAL™ generates the SHA-384 fingerprint and requests the timestamp on your own device. The file itself is never uploaded, so client work does not pass through anyone else's server. What you keep is a Receipt of Provenance Record and an Evidence Bundle containing the fingerprint, the timestamp, and the certificate chain — verifiable by anyone, on any machine, without an account.

• Seal each meaningful draft as you create it, not at the end
• Seal before the file is sent, shared, or posted anywhere
• Keep the Receipt of Provenance Record alongside the project files
• By delivery day you have a dated record for every version, built in real time

Building a Revision Trail That Reads as Evidence

Naming is the foundation of a clean chain of title. A format like ClientName_Logo_v03_2026-03-12_colour-revision.ai captures the project, asset type, version, an ISO date that sorts correctly, and what changed. Consistent naming creates a visible, ordered development sequence that supports your timeline without requiring you to explain it.

Keep folder structure shallow and predictable: client at the top level, project beneath it, then drafts, finals, assets, and archive. Name folders for the work rather than the person doing it, so the structure survives handovers and transfers.

• Sealed receipts for each meaningful draft version
• The original brief or creative direction document
• Revision emails with the files actually attached
• A final delivery confirmation

Contracts and Registration: What Designers Get Wrong

Your contract determines who owns the logo, and many standard freelance agreements handle it poorly. A logo is two-dimensional artwork, and commissioned works only qualify as works made for hire if they fall within the categories enumerated in 17 U.S.C. § 101 — which a logo generally does not. A work-for-hire clause on its own may therefore fail to transfer ownership.

The more reliable approach pairs that clause with a present-tense assignment, conditioned on payment: "Designer hereby assigns to Client all right, title, and interest in and to the Logo… This transfer becomes effective upon receipt of full payment." The default under U.S. copyright law is that the creator retains ownership; a contract has to actively transfer it. This is general information, not legal advice — have an attorney review your agreement.

• Filing fees are $45 for a Single Application and $65 for a Standard Application
• Registration is required before filing an infringement suit in federal court
• Timely registration unlocks statutory damages from $750 to $30,000 per work
• Willful infringement can raise that ceiling to $150,000 per work
• Processing times vary — check copyright.gov for current estimates

When a Client Uses Your Logo Without Permission

Document the use before you contact anyone. Capture timestamped screenshots of every location the logo appears, with the page URL, the date, and enough context to show the mark clearly. Evidence disappears quickly once you make contact, and you need to show what existed at a specific moment.

A DMCA takedown notice under 17 U.S.C. § 512 is directed at the hosting platform rather than the infringer, and applies where the logo is displayed online by a service provider. A cease-and-desist goes to the party directly and is the better first move for offline misuse or a client exceeding what your agreement allows. If the notice is ignored, a counter-notice is filed, or the commercial impact is significant, that is the point to involve an IP attorney.

• Your physical or electronic signature
• Identification of the copyrighted work claimed to be infringed
• Identification of the infringing material and enough detail to locate it
• Your contact information
• A statement of good-faith belief that the use is unauthorised
• A statement, under penalty of perjury, that the notice is accurate and you are authorised to act

Build the Habit Before the Next Project

The proof has to exist before the question comes up. Designers with the strongest position in ownership disputes are rarely surprised by them — they sealed their drafts, named files consistently, wrote payment-conditioned assignment language into their contracts, and registered early when the commercial stakes warranted it.

You cannot go back and build evidence for work already delivered. On the next project, start the trail on day one. That is the only time it works.
