PME industrielle innovante : quels actifs immatériels protéger en priorité ?

Article juridique - Droit de la propriété intellectuelle

Par Me Sophie PENNARUN

PME industrielle innovante : quels actifs immatériels protéger en priorité ?

La valeur d'une PME industrielle repose en grande partie sur des actifs immatériels. Pourtant, la plupart négligent encore leur protection juridique.

Une machine-outil de 500 000€ sera assurée, surveillée, entretenue. Mais le procédé de découpe qui fait la différence face à la concurrence ? Le logiciel de pilotage développé sur 3 ans ? La base clients constituée depuis 10 ans ? Souvent laissés sans protection.

L'erreur classique : se focaliser uniquement sur les brevets. Une PME métallurgique que j'accompagne a découvert que sa vraie valeur résidait dans ses paramètres d'optimisation thermique (secret d'affaires) et sa marque produit reconnue par les bureaux d'études. Pas dans son brevet sur l'alliage, facilement contournable.

La méthode qui fonctionne : cartographier d'abord tous ses actifs immatériels, puis hiérarchiser selon leur impact concurrentiel. Un savoir-faire critique mérite parfois une vraie réflexion stratégique : le secret ne s'épuise jamais, contrairement aux 20 ans de monopole conféré par un brevet.

Le dirigeant qui protège intelligemment ses actifs incorporels prend 10 longueurs d'avance. Celui qui attend prend le risque de voir partir sa valeur avec son ingénieur ou face à un concurrent plus malin.
