https://www.copyright.eu/en/docs-category/inventions-et-prototypes/ write me what it offers for protection:
On the Copyright.eu – Inventions and Prototypes website, Datasure presents the possibilities of protecting inventions, technical solutions and prototypes.
I also studied their specific document on the protection of inventions. Here is exactly what they offer.
1. What protection does Copyright.eu provide?
1. Certificate of Anteriority
This is their main service for inventors.
It allows you to:
• Register the documentation of the invention.
• Save technical drawings, photographs, 3D models, descriptions and documentation of the prototype.
• Obtain a qualified electronic time stamp.
• Prove that you owned a specific technical solution on a certain date.
• Obtain a certificate that can serve as evidence in a possible legal dispute.
The certificate can be supplemented with an officially certified document from a bailiff (Bailiff).
2. Right of prior personal use
This is a very interesting part of their service.
Copyright.eu states that the certificate can help prove the right of prior personal use under the French Intellectual Property Code (Article L.613-7).
In practice, this means that under certain conditions you can continue to use the invention personally, even if someone else later patents the same solution.
Please note that this is a legal principle with specific conditions, not an automatic right guaranteed by the certificate itself.
3. Protection in negotiations with investors and manufacturers
Copyright.eu allows you to document your invention before you present it to:
• An investor.
• A manufacturer.
• A business partner.
• A development company.
• A potential distributor.
If someone were to misuse your confidential information, the certificate can help prove that you owned the solution earlier.
They recommend concluding an NDA – a non-disclosure agreement.
4. Protection against future patenting by another person
A certificate can be important evidence in a situation where someone later files a patent application for the same technical solution.
Important: However, a certificate is not a patent and does not automatically prevent another person from filing a patent application.

2. What does Copyright.eu NOT provide?
This is the most important distinction.
Type of protection Copyright.eu
Proof of the date of existence of the invention Yes
Timestamp of the documentation Yes
Certificate of priority Yes
Proof of earlier ownership of the documentation Yes
Evidential support in legal disputes Yes
Patent for invention No
Automatic prohibition of copying the technical solution No
Exclusive right to manufacture the product No
Automatic international patent protection No
These differences are also confirmed by their own documentation.
3. How would I use their protection in practice?
If you are developing your own product or technical device, I would proceed as follows:
1. Prepare technical documentation for the invention.
2. Document the prototype, including photos, drawings and a technical description.
3. Save the documentation to Copyright.eu.
4. Obtain a certificate of priority.
5. Use an NDA when negotiating with partners.
6. Then file a patent application if the solution meets the patent conditions.
This way you will create an evidentiary trail even before filing a patent application.
Very important: Do not publish the invention before filing a patent application. Public disclosure can destroy its novelty and make it impossible to obtain a patent.
