Notarisation numérique en Suisse : pourquoi ZertES remplace la notarisation

La notarisation en Suisse coûte CHF 200–500 et prend des jours. Un sceau qualifié ZertES selon SR 943.03 offre la même présomption légale en moins de 2 minutes à CHF 5 par document.

Au printemps 2024, une startup logicielle genevoise etait a deux semaines de conclure une Serie B. L'equipe juridique de l'investisseur principal a reclame une preuve certifiee de la propriete intellectuelle sur le codebase principal, notamment la preuve que l'equipe fondatrice avait developpe le logiciel avant qu'un ancien prestataire formule une revendication concurrente. Les avocats de la startup ont pris trois rendez-vous chez des notaires dans deux cantons. Le premier creneau disponible etait a 11 jours ouvrables. La fenetre de financement s'est fermee avant l'arrivee des certifications. La startup a perdu la levee de fonds. La PI contestee, si elle avait ete scelle sous ZertES SR 943.03 au moment de chaque commit, aurait coute CHF 5 par fichier. La voie notariale, arrivee trop tard, a coute CHF 1 400 et 11 jours.

Ce decalage de temps est la realite operationnelle de la certification notariale traditionnelle en Suisse. ZertES fournit un equivalent legal en moins de deux minutes, a une fraction du cout, sans rendez-vous necessaire.

The CHF 5 file that can save a CHF 200,000 IP dispute

Most IP disputes are not decided by who had the better idea. They are decided by who can prove it. A qualified electronic seal under ZertES Art. 14 and eIDAS Art. 25(2) shifts the legal burden of proof to the opposing party. Without one, you spend the dispute explaining yourself.

Why a US copyright registration does not protect you outside the United States

A US copyright registration is a powerful thing inside one legal system and close to inert outside it. This is why it does not cross the border, what national treatment actually carries with it, and what a European rights holder can rely on instead.

The world has no copyright register, except the United States. Why that matters.

Under the Berne Convention, copyright arises automatically on creation in over 180 countries, with no registration required. Almost none of those countries keep a record of it. That gap is invisible until the day somebody disputes who made something first.
