3. In the actions referred to in points (a) and (c) of Article 124, a plea relating to revocation of the EU trade mark submitted otherwise than by way of a counterclaim shall be admissible where the defendant claims that the EU trade mark could be revoked for lack of genuine use at the time the infringement action was brought.
