Article L614-12 of the French Intellectual Property Code

As far as France is concerned, the European patent shall be declared invalid by a court decision on any of the grounds referred to in Article 138(1) of the Munich Convention.

If the grounds for invalidity affect the patent only in part, invalidity shall be declared in the form of a corresponding limitation of the claims.

In an action for invalidity of the European patent, its proprietor is entitled to limit the patent by amending the claims in accordance with Article 105a of the Munich Convention; the patent thus limited constitutes the subject matter of the invalidity action brought.

A party who, during the same proceeding, proceeds to several limitations of its patent in a dilatory or abusive manner may be ordered to pay a civil fine of a maximum amount of 3,000 euros, without prejudice to any damages that may be claimed.

Article L614-12

La nullité du brevet européen est prononcée en ce qui concerne la France par décision de justice pour l’un quelconque des motifs visés à l’article 138, paragraphe 1, de la Convention de Munich.

Si les motifs de nullité n’affectent le brevet qu’en partie, la nullité est prononcée sous la forme d’une limitation correspondante des revendications.

Dans le cadre d’une action en nullité du brevet européen, son titulaire est habilité à limiter le brevet en modifiant les revendications conformément à l’article 105 bis de la convention de Munich ; le brevet ainsi limité constitue l’objet de l’action en nullité engagée.


La partie qui, lors d’une même instance, procède à plusieurs limitations de son brevet de manière dilatoire ou abusive peut être condamnée à une amende civile d’un montant maximum de 3 000 euros, sans préjudice de dommages et intérêts qui seraient réclamés.
