For €210. Same day. In your own language. Then you have 12 months to test it, present it, do market research, and find the right patent lawyer for your European patent.
Get Protected Today →You have an invention. You want to test it, present it, do market research, talk to investors. But you can't—not until you're protected.
And a European patent costs €5,000+. Finding the right lawyer for your specialty takes time. Time you don't have if you can't talk to anyone.
Any of these before you're protected = you lose your European patent rights forever:
Present at a trade show
Pitch to investors
Email a supplier
Post on LinkedIn
Ask a factory for a quote
Do market research
Test with potential users
Ask around for the right patent lawyer
The date you're protected is the date that counts. Everything published after that date cannot be used against you—including your own disclosures.
We help you get official, government-stamped proof of your invention date. You can write your description in any language. No translation needed.
Your protection is recognized by the European Patent Office and over 170 countries thanks to international treaties.
Get protected today. Then you have 12 months to file your European patent.
Write in the language you think in. No translation required.
Once you're protected, you can finally move forward:
Show it. Get feedback. See if there's real demand before spending thousands on a full patent.
Pitch freely. You're protected. Nothing they hear can be used against your patent.
Talk to potential customers. Understand your market. Make informed decisions.
Take your time. Ask around. Find a patent lawyer who really knows your specialty—not just the first one you find.
The EPO changed its rules (decisions G1/22 and G2/22). Before, lawyers warned about paperwork complications with this approach. Now, the EPO accepts it without the old bureaucratic hurdles. The main objection is gone.
Write it in your own language. Add drawings. You know your invention better than anyone.
Step-by-step help through the process. We check everything before submission.
Official confirmation of your invention date. You can now say "Patent Pending."
Time to find the right lawyer, prepare properly, and file your European patent.
Patent Vault is a service of DryCake SA, a Belgian company. We've been through the patent process ourselves—multiple times. We know what it's like to need protection before you can afford a lawyer.
We created Patent Vault because European inventors deserve the same early protection that exists elsewhere. Lock your date first. Then take your time to do everything right.
Patent Vault helps you get official proof of your invention date. We are not patent attorneys and do not provide legal advice.
This protection establishes your invention date—it does not grant patent rights. Within 12 months, you need to file a patent application to pursue a granted patent.
Some European countries require a national filing first. We'll check this with you before you start.
For specific legal questions, consult a qualified patent attorney.
