Article L612-4 of the French Intellectual Property Code

The patent application may relate to only one invention or to a plurality of inventions linked together in such a way that they form a single general inventive concept.

Any application which does not comply with the provisions of the preceding paragraph must be divided within the prescribed period; divisional applications shall benefit from the filing date and, where applicable, the priority date of the initial application.

Original in French 🇫🇷
Article L612-4

La demande de brevet ne peut concerner qu’une invention ou une pluralité d’inventions liées entre elles de telle sorte qu’elles ne forment qu’un seul concept inventif général.

Toute demande qui ne satisfait pas aux dispositions de l’alinéa précédent doit être divisée dans le délai prescrit ; les demandes divisionnaires bénéficient de la date de dépôt et, le cas échéant, de la date de priorité de la demande initiale.
