An action for damages based on article L. 481-1 shall be barred on expiry of a period of five years. This period begins to run from the day on which the claimant knew or should have known cumulatively:
1° The acts or facts imputed to one of the natural or legal persons mentioned in Article L. 481-1 and the fact that they constitute an anti-competitive practice;
2° The fact that this practice causes him damage;
3° The identity of one of the perpetrators of this practice.
However, the statute of limitations does not run until the anti-competitive practice has ceased.
It does not run in respect of the victims of the beneficiary of a total exemption from a pecuniary penalty pursuant to a leniency procedure as long as they have not been able to take action against the perpetrators of the anti-competitive practice other than that beneficiary.
