Reusing a competitor's concept does not, in itself, amount to an act of economic free-riding (parasitisme). According to the Cour de cassation (France's highest civil court), a company claiming to be the victim of free-riding must identify the individualised economic value it relies on, the fruit of know-how or of human and financial effort. That value cannot be inferred either from the mere finding that a concept exists or from the mere fact that it was marketed first (Com., 23 September 2026, No. 25-14.331).
Key points
- Economic free-riding is a fault based on Article 1240 of the French Civil Code: an operator follows in the wake of another in order to take undue advantage of its efforts, know-how, reputation or investments.
- Reusing, with variations, a concept implemented by a competitor does not in itself constitute an act of free-riding, since ideas are free for all to use.
- A company claiming to be the victim of free-riding must identify the individualised economic value it relies on, the fruit of know-how or of human and financial effort.
- Having been the first to market a concept is not enough to establish its individualised economic value: that value cannot be inferred from precedence alone.
- Finding that a concept exists, even one presented as distinctive, is not enough: the court must establish an identified and individualised economic value.
Reuse of a commercial concept: what the Court holds
The commercial chamber holds that the existence of a concept and the fact that it was marketed first are not sufficient to establish economic free-riding. The alleged victim must identify an individualised economic value, the fruit of its reputation, its know-how or its human and financial effort. The court of appeal, which had not established that value, had therefore not provided sufficient legal basis for its order against the competing companies.
A company had created, for bakeries, a concept of promotional events around Epiphany. The concept was based on tokens struck with the crests of the teams in the professional rugby and football championships, used under licence. Launched in 2016 in a first bakery, it was extended in 2017 to other bakeries. A partner company had entered into a partnership agreement with the company that devised the concept, which was subsequently placed in compulsory liquidation (liquidation judiciaire).
The company that devised the concept, represented by its liquidator, another company and that company's manager (gérant) sued several companies for unfair competition. They accused them of marketing, for Epiphany 2018, a product imitating their token concept. According to the court of appeal, those companies had sold bakers a kit comprising tokens bearing the image of a football championship, cake bags, crowns and posters.
The decision under appeal (CA Aix en Provence, 26 February 2025, No. 20/09177) had found acts of free-riding committed on the occasion of Epiphany 2018. It had ordered the competing companies to compensate the claimants' economic loss and the manager's non-pecuniary loss. The commercial chamber partially quashes that decision because no economic value had been established. It remits the case to the Aix-en-Provence court of appeal, differently constituted.
The commercial chamber first sets out the definition of free-riding, on the basis of Article 1240 of the French Civil Code. It then specifies the burden of proof borne by the alleged victim. Finally, it lays down the freedom to reuse an idea.
It follows from this provision that economic free-riding is a form of unfairness, constituting a fault, which consists, for an economic operator, in following in the wake of another in order to take undue advantage of its efforts, its know-how, the reputation it has acquired or the investments it has made. It is for whoever claims to be the victim of acts of free-riding to identify the individualised economic value they rely on, the fruit of know-how or of human and financial effort. Since ideas are free for all to use, the mere fact of reusing, with variations, a concept implemented by a competitor does not, in itself, constitute an act of free-riding.
The court of appeal had held the concept to be "distinctive since it has not been shown that it is a reuse of a customary commercial operation". It had inferred from this "that it embodies an economic value capable of fraudulent appropriation". The commercial chamber criticises it for reaching its decision "after merely finding that a concept existed, without establishing an identified and individualised economic value". It adds that this value "could not be inferred from the mere fact that it was marketed first".
Free-riding: what the victim company must prove
A company claiming to be the victim of free-riding must pinpoint the economic value it considers to have been captured, and not merely show that a competitor has reused its idea. The Cour de cassation requires an individualised economic value, that is to say one that is identified and specific to the party relying on it. That value must be the fruit of know-how or of human and financial effort. The mere existence of a concept does not meet this requirement.
The rule that ideas are free for all to use means that an idea, as such, belongs to no one. A company may therefore reuse a concept implemented by a competitor, with variations, without committing a fault by that fact alone. Free-riding requires more: following in the wake of another operator in order to take undue advantage of its efforts, know-how, reputation or investments.
Precedence does not replace that proof. According to the Cour de cassation, having launched a concept first does not establish the existence of an individualised economic value. In the case at hand, the absence of proof that the concept reused a customary commercial operation was no more sufficient. The claimant must show what it has actually acquired or invested: reputation, know-how, human and financial effort.
Article 1240 of the French Civil Code is the basis for this liability. It provides that "Any act whatsoever of a person which causes damage to another obliges the person by whose fault it occurred to make reparation for it". The Cour de cassation characterises free-riding as a form of unfairness constituting a fault. Under that provision, compensation therefore requires damage caused by that fault.
What scope for the protection of a commercial concept?
The decision under review makes the identification of an individualised economic value a condition of the fault of free-riding. The commercial chamber defines free-riding by reference to what the operator takes undue advantage of: the efforts, know-how, acquired reputation or investments of another. The court must establish an identified and individualised economic value, the fruit of the acquired reputation or of the know-how and the human and financial effort invested by the alleged victim, before characterising the reuse as wrongful.
The court of appeal had taken a broader approach. It held to be fraudulent the identical or very similar reuse of a concept, the operator deliberately following in the wake of a competitor without any financial consideration. The commercial chamber is not satisfied with this reasoning based on resemblance and precedence: it requires that the captured value first be identified and individualised.
The solution reconciles free competition with the protection of investments. A concept may be protected against free-riding where its creator establishes the economic value it represents. The reuse of a concept becomes wrongful where it makes it possible to take undue advantage of the efforts, know-how, reputation or investments of the party that developed it.
Commercial concept and free-riding: the right reflexes
Every company, whether it creates a concept or draws inspiration from a competitor's, would do well to think in terms of identifiable economic value rather than in terms of ideas. The commercial chamber's solution makes recognition of free-riding dependent on proof of that value. The useful steps differ according to the company's position.
For the company that creates and exploits a concept
- Identify what, in the concept, constitutes a specific economic value: know-how, acquired reputation, investments, human and financial effort.
- Keep a record of those efforts throughout development: expenditure incurred, time spent, contracts concluded, commercial returns and reputation gained.
- Do not rely on the launch date alone: having been the first to market the concept does not, on its own, prove its economic value.
- Distinguish the general idea, which any competitor may reuse, from what genuinely results from the company's own work and investments.
For the company drawing inspiration from an existing concept
- Check whether the element reused is a general idea, which any operator may adapt, or the identifiable fruit of a competitor's efforts.
- Refrain from taking advantage of a competitor's reputation, know-how or investments: it is this undue advantage that characterises free-riding.
- Keep a record of the company's own design choices and investments, which document an independent approach.
Frequently Asked Questions
A competitor reuses a commercial concept I created by adapting it: is that necessarily free-riding?
No, not in itself: reusing a concept only becomes free-riding if the competitor takes undue advantage of your efforts, know-how, reputation or investments. The Cour de cassation holds that ideas are free for all to use. The mere fact of reusing, with variations, a concept implemented by a competitor therefore does not constitute an act of free-riding (Com., 23 September 2026, No. 25-14.331).
I consider myself the victim of free-riding by a competitor: what must I prove about my concept?
You must identify the individualised economic value you rely on, which must be the fruit of know-how or of human and financial effort. The Cour de cassation places this burden on whoever claims to be the victim of acts of free-riding. Showing that a concept exists and that a competitor reused it is not enough: the value must be identified and linked to the victim's acquired reputation, know-how or investments.
I was the first to market my concept: is that enough to establish free-riding by my competitor?
No, precedence is not enough, even if the concept appears original. The Cour de cassation holds that economic value cannot be inferred merely from the fact that the concept was marketed first. It found insufficient reasoning that inferred this value from the distinctive nature of the concept. The court must establish an identified value, the fruit of the acquired reputation or of the know-how and the human and financial effort of the company.
I am drawing inspiration from a commercial operation launched by a competitor: at what point do I commit economic free-riding?
You commit economic free-riding when you follow in the wake of that competitor in order to take undue advantage of its efforts, its know-how, the reputation it has acquired or the investments it has made. The Cour de cassation characterises this behaviour as a form of unfairness constituting a fault. Reusing the idea itself, with variations, is not enough to establish that fault, since ideas are free for all to use.
A competitor has committed economic free-riding to my detriment: is it liable?
Yes, provided that the free-riding has caused you damage. Article 1240 of the French Civil Code obliges the person by whose fault damage has been caused to another to make reparation for it. The Cour de cassation bases economic free-riding on this provision and characterises it as a fault. Compensation therefore requires both the fault, which calls for the identification of an individualised economic value, and damage resulting from it.
