For about 100 years now, the French Patent & Trademark Office (INPI) has been offering the Soleau envelope service that allows one to deposit two copies of a document with the Office, individually sealed in envelopes that are stamped and perforated by INPI. One envelope is then returned to the deponent. The Office keeps their copy for five years, during which the deponent can request its return by mail and the idea of course is that this can prove the age of a document because the two envelopes can be opened, for example, in a court. Deposition itself confirms no rights, however. It simply provides a cheap way to prove authorship or prior art etc. and the current price of the service, for up to seven A4 pages, is €15.
There is now an electronic version for which INPI provides an electronic fingerprint (hash) and stores the original file (in the owner's account). This is better described at the French-language link below. Casual inspection did not reveal a public proof checking facility, something that is in fact provided by the company MaPreuve, for example. MaPreuve requires a Java application, which none of the browsers on this computer wanted to load, but this would be a really useful service. Storing the original document electronically, in my view, detracts from the value of the INPI service and I would have been happier if they had just stored the electronic fingerprint.
