En mars 2026, un cabinet IP zurichois a recu un message urgent d'un client, une entreprise logicielle: un ancien partenaire revendiquait la copropriete d'un outil produit que l'equipe avait construit avant qu'un accord de partenariat existe. Le client avait des e-mails et des journaux Slack internes. Ce qu'il n'avait pas, c'etait un seul document portant un horodatage qualifie d'un prestataire de services de certification accredite. Le premier appel aux avocats adverses a dure quatre minutes. L'affaire a pris huit mois.

Toutes les signatures numeriques ne sont pas equivalentes. En Suisse et dans l'UE, il existe une distinction juridique claire entre les types de signature. Comprendre cette distinction, et agir en consequence avant qu'un litige survienne, separe la documentation executable des documents qui s'effondrent sous examen.
