Copyright vs trademark for logos
- Copyright protects the logo as an original artistic work — the specific graphic. It's automatic when you create it and can be registered on Form VA (Visual Arts) at copyright.gov.
- Trademark protects the logo as a brand identifier in commerce — stopping competitors from using a confusingly similar mark. That's registered with the USPTO at uspto.gov, not the Copyright Office.
For a brand, the trademark is usually the important one, but copyright still protects the artwork itself, and the two can coexist.
Why dated proof of the design matters
Logo design is collaborative and iterative — freelancers, agencies, contests, AI tools, revisions. Ownership fights over "who designed it" are common, especially when a designer and a client disagree, or when you discover a near-identical mark and need to show you used yours first.
A blockchain timestamp gives you a permanent record that your exact design file (the source file, export, or brand guide) existed on a specific date. BlockchainSign hashes the file locally in your browser and writes the fingerprint to Ethereum, returning a lifetime certificate. It's fast, cheap evidence of creation that supports both a copyright claim and a "first use" trademark argument.
