Trademark proof of use
Build a verifiable record of how your trademark is used. Certify packaging, campaigns and sales records as they happen, ready for registrations, renewals and any challenge to your mark.
Keep the evidence while your brand is in use
Packaging changes. Campaigns end. Websites get redesigned. When your trademark is challenged years later, rebuilding that history can be hard.
Capture the evidence as business happens: what your mark looked like, which goods or services it was on, where and when it was used, and how much you sold. You may need it for a Declaration of Use with the USPTO, or to answer a non-use revocation action at the EUIPO. Even a validly registered trademark can be lost if you can't show the required use.
Bernstein certifies each file on the Bitcoin blockchain. On Scale and Enterprise plans, you also get separate timestamps from an EU qualified and a Chinese trusted timestamp authority. Your files stay in encrypted, versioned storage, ready to check whenever you need them.
How Bernstein helps
Certify evidence as you collect it
Independent proof that each file existed, unchanged, on a given date. Not just file dates anyone can edit.
Keep your evidence in one place
Product images, packaging, campaigns and sales records from your teams, agencies and consultants, organized by trademark, market and period.
Preserve your brand's history
Earlier packaging, campaigns and web pages stay available as they change. Build your record over time, not in a rush when challenged.
Strengthen your position in proceedings
Certified files and independently verifiable timestamps to back your claims before trademark offices or courts.
How it works
Collect evidence of actual use
Gather materials showing your mark in commercial use, with their dates, markets, goods or services and sales figures.
Certify your materials
Upload your files and certify them on the Bitcoin blockchain in a few clicks.
Keep your record current
Add evidence as products launch, campaigns run and sales grow. Earlier versions stay available.
Produce evidence when needed
Pull the files and certificates you need for filings, renewals or disputes. Anyone can verify them independently, without Bernstein.
Types of usage evidence
Keep materials that link your mark to real commercial activity. Pick what fits the goods, services, markets and period you need to cover.
