When starting a business in France, choosing your visual and verbal identity is a crucial step to attract customers and stand out from the competition. Yet, many entrepreneurs still confuse the corporate name, trade name, and shop sign, wrongly assuming that a simple registration with the Registre du Commerce et des Sociétés (RCS - Registry of Commerce and Companies) offers absolute protection. Understanding the legal subtleties of these three concepts and mastering the mechanisms of their protection is essential to secure your investment and avoid costly disputes.

To effectively protect your business's identity, you must first clearly distinguish between the three legal concepts that comprise it. Although they can be identical for the same business, they are subject to distinct definitions and legal frameworks.
The corporate name designates the legal identity of the company as a legal entity (personne morale). It must appear in the company's articles of association (statuts) and is registered with the Registre National des Entreprises (RNE - National Register of Businesses) during incorporation. This is the official name that appears on all administrative, tax, invoice, and payslip documents.
The trade name is the name under which the business's activity is known to the general public and customers. It is the tool used to rally customers. A company can have a complex administrative corporate name and use a much shorter, more memorable trade name for its daily operations.
The sign is the visible marker that identifies and physically locates a business premises (shop, workshop, office). It is generally displayed on the facade of the building. The sign individualises the physical point of sale in relation to its geographical competitors.

Unlike a trademark, which is protected exclusively by filing an application with the Institut National de la Propriété Industrielle (INPI - National Institute of Industrial Property), the protection of the corporate name, trade name, and shop sign relies on different legal mechanisms, primarily linked to usage and temporal priority.
Under French law, the right to a trade name and a shop sign is born from first public, personal, and continuous use. It is not necessary to file a patent or trademark application for these elements to be protected.
Protection of the corporate name, on the other hand, is acquired as soon as the company is registered with the Registre du Commerce et des Sociétés (RCS), in accordance with the rules of the Code de commerce (French Commercial Code).
When a competitor uses an identical or similar trade name or shop sign that is likely to cause confusion in the minds of the public, the legitimate owner can take legal action.
This protection is based on extra-contractual civil liability, governed by *Article 1240 of the Code civil** (French Civil Code, formerly Article 1382), which states: “Any human act whatsoever which causes damage to another obliges him by whose fault it occurred to make reparation for it”*.
To win the case, the plaintiff must prove three elements:
1. *Fault (Faute):* The use of a similar name creating a risk of confusion.
2. *Harm (Préjudice):* A loss of customers, a drop in turnover, or damage to reputation (disparagement, dilution of image).
3. *Causal Link (Lien de causalité):* Proof that the harm stems directly from the competitor's wrongful use of the name.
The protection offered to a trade name and a shop sign is not absolute and unlimited:

To secure your company's identity and avoid having to change your name after a few months of business, here is the rigorous protocol to follow:
Before definitively adopting a name, you must ensure it is available.
1. Consult the INPI database (DATA INPI) free of charge to check existing corporate names, trademarks, and trade names.
2. Search the business directory and the registry of the commercial court (Infogreffe).
3. Perform an "identical" search and then a "spelling and phonetic" search (similarity search) to avoid risks of visual or acoustic confusion.
4. Check the availability of the corresponding internet domain name (.fr, .com extensions, etc.) with an approved registrar (such as OVH or Gandi).
When creating your business on the Guichet Unique Électronique des formalités d'entreprises (the single electronic window for business formalities managed by INPI), make sure to carefully fill in the dedicated boxes:
1. Indicate your corporate name in the articles of association (statuts).
2. Explicitly declare your trade name if it differs from the corporate name.
3. Declare the shop sign of your physical establishment.
This information will then be registered in the RNE and will appear on your Kbis extract (official company registration certificate), constituting official initial proof of the date of your first use.
Since the right to a trade name and shop sign arises from use, you must carefully collect and archive all dated proof of this use:

Protecting a company's identity involves financial investments and specific timelines that should be anticipated.

To better understand how French courts apply these rules, let us analyse two fictional but representative situations based on current case law.
Situation: Sophie opens a beauty and hair salon in Lyon under the sign "L'Atelier de Beauté" in 2021. She generates an annual turnover of €80,000. In 2023, a competitor sets up on the same street and displays the sign "L'Atelier Beauté de Sophie". Sophie immediately notices a 15% drop in her clientele, who are confused by the similarity of the names, representing a direct financial loss of €12,000.
Legal Resolution: Sophie takes the competitor to the Commercial Court (Tribunal de commerce) in an action for unfair competition. She provides her 2021 invoices for the installation of her sign and her annual accounts as proof. The court notes the obvious risk of confusion (same activity, same street, almost identical names). The competitor is ordered to:
Situation: In 2018, Jean created a plumbing and heating business in Bordeaux under the trade name "Aquatech", registered with the RCS. In 2022, a start-up launches in Bordeaux under the corporate name "Aquatech SAS" to market high-tech water filters for industrial swimming pools. Jean believes his name has been stolen and threatens to sue the start-up.
Legal Resolution: Although located in the same geographical area (Bordeaux), the business sectors and target clienteles are radically different (individuals for plumbing repairs vs industries for pool filtration). There is no risk of confusion for the average consumer. If Jean sues the start-up, his action will be dismissed by the judges because no commercial harm can be demonstrated.

To safeguard your business against the risk of losing your brand or facing a lawsuit, absolutely avoid these common pitfalls:
---
A trademark is an industrial property title issued by INPI after examination of an application. It grants a national monopoly of exploitation for defined products or services. A trade name, on the other hand, is acquired through use and protects the business against unfair competition only within its actual area of activity and geographical zone of influence.
Using your own patronymic is a right, but it is limited by the principle of loyalty. If your surname is already used by a famous competing company in the same sector, you must use it in a way that avoids any confusion (for example, by obligatorily adding your first name or a distinctive qualifier) to avoid being accused of free-riding (parasitisme).
Proof is unrestricted under commercial law. You can use any means at your disposal: invoices from the contractors who installed the sign, dated photographs certified by a commissaire de justice (formerly huissier - bailiff), press clippings, commercial lease agreements, or certified posts on professional social networks.
Buying a domain name (e.g., mybusiness.fr) does not in itself constitute legal protection for commercial use. However, if the website is active and publicly operated, it contributes to establishing the use of your trade name and can serve as a basis to oppose the subsequent registration of an identical trademark by a third party in the same business sector.
