Ce service de l&rsquo;Institut national de la propri\u00e9t\u00e9 industrielle (INPI) attribue une date certaine \u00e0 un contenu, sans le rendre public. Ouvert \u00e0 toute personne physique ou morale, il convient aussi bien \u00e0 un designer qu&rsquo;\u00e0 un chercheur ou \u00e0 une entreprise.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Depuis le 1er avril 2024, le dispositif existe sous une forme exclusivement \u00e9lectronique : l&rsquo;e-Soleau.<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">L&rsquo;histoire de l&rsquo;enveloppe Soleau<\/h2>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Eug\u00e8ne Soleau, un industriel au service des cr\u00e9ateurs<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Eug\u00e8ne Soleau est un fabricant de bronzes d&rsquo;art, qui pr\u00e9side \u00e0 partir de 1900 le Syndicat des fabricants de bronze. Il milite activement pour la protection des cr\u00e9ations des industries d&rsquo;art. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Vers 1910, il imagine une enveloppe double et perfor\u00e9e, permettant de dater un document sans en r\u00e9v\u00e9ler le contenu. Il prot\u00e8ge ce dispositif par des brevets d\u00e9pos\u00e9s. Vers 1914, l&rsquo;INPI, en fait un service officiel. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pendant un si\u00e8cle, le fonctionnement varie peu. Le d\u00e9posant glisse deux exemplaires identiques de sa description dans les deux compartiments de l&rsquo;enveloppe. L&rsquo;office perfore l&rsquo;ensemble pour le dater. Il conserve un compartiment et renvoie l&rsquo;autre au d\u00e9posant. <\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">De l&rsquo;enveloppe papier \u00e0 l&rsquo;e-Soleau<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">L&rsquo;INPI lance le service num\u00e9rique e-Soleau en 2016. Les deux formats papier et num\u00e9rique coexistent jusqu&rsquo;au 31 mars 2024. Depuis, seule la solution \u00e9lectronique est possible. <\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Que d\u00e9poser dans une enveloppe Soleau ?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">L&rsquo;enveloppe e-Soleau accepte tout fichier num\u00e9rique. La nature de la cr\u00e9ation importe peu : une solution technique, une \u0153uvre graphique ou un concept commercial peuvent y figurer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La valeur d&rsquo;un d\u00e9p\u00f4t tient d&rsquo;abord \u00e0 sa lisibilit\u00e9. Un juge doit pouvoir identifier la cr\u00e9ation sans explication compl\u00e9mentaire. Une courte note de pr\u00e9sentation, jointe aux fichiers contenant les croquis, plans, cachier des charges etc., facilite cette lecture.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Le contenu se fige d\u00e8s la validation du d\u00e9p\u00f4t, il n&rsquo;est pas modifiable. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Deux modes de conservation coexistent. Dans le premier, l&rsquo;INPI archive les fichiers eux-m\u00eames, dans la limite de 100 fichiers et 2 Go. Dans le second, il ne garde que leur empreinte num\u00e9rique, sans limite de volume. Cette option convient aux fichiers lourds, mais elle transf\u00e8re la charge de conservation au d\u00e9posant. Un original perdu ou retouch\u00e9 prive alors l&#8217;empreinte de toute utilit\u00e9.<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Co\u00fbt et dur\u00e9e : raisonner en fonction du risque<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Le prix d\u00e9pend de deux variables : le volume d\u00e9pos\u00e9 et la dur\u00e9e de conservation. Chaque p\u00e9riode de cinq ans co\u00fbte 15 \u20ac jusqu&rsquo;\u00e0 50 Mo, plus 10 \u20ac par tranche de 50 Mo au-del\u00e0. La conservation peut atteindre 20 ans.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Le titulaire fixe la dur\u00e9e d\u00e8s le d\u00e9p\u00f4t ou la prolonge ensuite. Il doit toutefois agir avant la fin de la p\u00e9riode en cours : une fois celle-ci \u00e9coul\u00e9e, plus aucune prolongation n&rsquo;est possible. Les sommes vers\u00e9es \u00e0 ce titre ne sont pas remboursables.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Le bon horizon d\u00e9pend de la dur\u00e9e pendant laquelle un litige reste envisageable. Pour une invention exploit\u00e9e sur le long terme, une conservation courte risque de faire dispara\u00eetre la preuve au moment o\u00f9 elle devient utile. L&rsquo;ancienne enveloppe papier plafonnait d&rsquo;ailleurs \u00e0 dix ans, contre vingt aujourd&rsquo;hui.<\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Quelle valeur juridique pour l&rsquo;enveloppe Soleau ?<\/h2>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Une preuve de date et d&rsquo;int\u00e9grit\u00e9<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Le d\u00e9p\u00f4t donne lieu \u00e0 un r\u00e9c\u00e9piss\u00e9 \u00e9lectronique. Celui-ci horodate l&rsquo;op\u00e9ration, identifie les pi\u00e8ces et associe \u00e0 chaque fichier une empreinte num\u00e9rique. La signature \u00e9lectronique de l&rsquo;INPI emp\u00eache toute alt\u00e9ration du r\u00e9c\u00e9piss\u00e9.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Le titulaire garde la main sur son d\u00e9p\u00f4t. Il peut en consulter le contenu sans mettre fin \u00e0 la conservation, ou en demander la restitution d\u00e9finitive, qui entra\u00eene sa destruction. Il peut aussi en c\u00e9der la titularit\u00e9. Ces d\u00e9marches exigent le code confidentiel remis lors du d\u00e9p\u00f4t : mieux vaut le conserver avec soin.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Un moyen de preuve, pas un titre de propri\u00e9t\u00e9<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">L&rsquo;enveloppe Soleau ne conf\u00e8re aucun droit de propri\u00e9t\u00e9 intellectuelle sur son contenu. Elle ne permet donc pas, \u00e0 elle seule, d&rsquo;interdire une exploitation par un tiers ni d&rsquo;agir en contrefa\u00e7on. Son utilit\u00e9 varie selon le droit en cause :<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">L&rsquo;enveloppe Soleau aide \u00e0 \u00e9tablir l&rsquo;ant\u00e9riorit\u00e9 d&rsquo;une \u0153uvre, documenter la chronologie de cr\u00e9ation, ou peut permettre d&rsquo;\u00e9tablir une exception de possession personnelle ant\u00e9rieure en <a href=\"https:\/\/leca-sevestre.com\/it\/diritto-dei-brevetti\/\">droit des brevets<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Concr\u00e8tement, l&rsquo;enveloppe Soleau prouve qu&rsquo;un contenu existait, \u00e0 une date donn\u00e9e, entre les mains du d\u00e9posant. Elle ne d\u00e9montre pas, \u00e0 elle seule, qu&rsquo;il en est l&rsquo;auteur. Le juge appr\u00e9cie sa force probante au regard des autres \u00e9l\u00e9ments du dossier.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">e-Soleau ou entiercement ?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">L&rsquo;INPI donne acc\u00e8s \u00e0 un autre service similaire : l&rsquo;entiercement. Ce service pr\u00e9voit la remise de documents \u00e0 des tiers d\u00e9sign\u00e9s si certaines conditions surviennent, par exemple la d\u00e9faillance du d\u00e9posant. <\/p>\n\n\n\n<div style=\"height:25px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\">FAQ<\/h2>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>L&rsquo;enveloppe Soleau prot\u00e8ge-t-elle une id\u00e9e ?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Non.
