French Competition Law provides a comprehensive review of the French rules relating to competition: restrictive agreements, commercial negotiation, abuses of a dominant position, procedure and merger control.

French Competition Law

The situation is a little more complicated where the name in question is patronymic (a family name/surname). Everyone has the right to use his or her patronym as a means of distinguishing a business from competitors. The use of the name has to be real and personal, but if it is, the right usually exists even where the name has already been trademarked. The above conditions are met where the holder …

Trade name and family name

Confusion is frequently created by the imitation of the elements that serve to identify an undertaking for the purpose of acquiring its clientele. In order to poach the customer-base of a competitor, an operator can imitate the distinctive signs of the company - logo, trade name, registered name, etc. in order to mislead the consumer as to the identity of the company in question. Technologies such as the internet have also opened up new ways of appropriating others' customers. 

However, such signs are not the only elements of brand identity. Advertising, commercial documents, exterior decoration are all aspects generating customer loyalty which can be imitated in order to create confusion with the image that the company has built. 

 Various elements of identity

The emblem (name and sign under which a business trades) of a business is a very important distinguishing element. The emblem used must do more than just identify the type of business - it must be particular and not generic , even if the association of generic and ordinary words can constitute a distinctive name liable to be covered by an exclusive right . On the other hand, an action in unfair competition which is available to persons not able to assert exclusive rights, does not require the sign to be original . 

Priority of use ensures that the trader has the right to prevent other traders from using the same emblem for a similar business . The protection varies according to the nature of the business and the notoriety of the emblem: it can extend to the same neighborhood and the same city  or to the whole of France . There is only unfair competition if the use of the emblem creates confusion in the minds of the public between two establishments of the same kind aimed at the same clientele . Where there is no actual direct copying, the similarities must be sufficient to cause confusion in the minds of moderately attentive customers .

Imitation of an emblem with very high recognition may be punishable when there is merely a danger of confusion; unfair competition suits in this case seek to check a parasitic practice whether or not a customer base is shared . 

Like for emblems, the competing use of another's trade mark under the form of a logo may create a risk of confusion between products and services or as to the origin of products or services, as the consumer may attribute them to one and the same undertaking . Confusion exists if the public may regard the logos of an operator as designating products or services of an undertaking economically linked to the undertaking having registered the logos as distinctive signs . However, as the free play of competition must prevail, in the absence of any official label or stamp, the use of a logo invoking, for example, ecology  is not unlawful.

Emblem ("enseigne") and logo

The protection of a trade name, under which people or companies carry out their business, raises questions similar to those involved in protecting trade marks. The trade name is the name under which the legal or natural person carries out its commercial activity whereas a trade mark designates the origin of the product or service. Both are identifying elements of a business, but there is no equivalent of an infringement action with respect to trade names, which are protected under the ordinary civil law on which fair competition rules are founded. 

Trade names, registered or not, have been protected in its contracting States since the 1883 Convention of the Union of Paris, irrespective of whether the trade name forms a part of a trade mark (Art. 8) but the definition of a trade name varies from country to country. In France, trade names are protected only where they are known or used on French territory .

Undertakings are free to choose the trade name as long as it does not infringe upon the rights of another person or business .  Rights to a trade name are acquired through use , and if the use stops, the right is lost . The right to the name is enforceable against third parties as soon as the legal entity is registered at the Trade and Companies Registry ("Registre du commerce et des sociétés") . Although a declaration of the chosen designation of the name to a professional order may constitute a criterion of assessment, the courts may prefer to base their decision on how long the copied sign has been in use . Protection depends on originality of the name  in the economic sector under consideration and geographical proximity of competitors . However, the success of an unfair competition action does not depend on originality or distinctiveness as they are merely possible criteria for the assessment of fault and risk of confusion , which is assessed in the context of the average, reasonably well informed and reasonably observant and circumspect consumer of the goods and services concerned . The same word can be used for a corporate name and a domain name, without risk of confusion, when the activities concerned are distinct by their nature, meet different needs and do not target the same clientele . However, even if the characterization of a risk of confusion between the usurped corporate name and the distinctive sign which imitates it must be done in accordance with the principles of specialty and territoriality, the application of the principle of specialty to the name does not require the activities of undertakings to be strcitly identical, because the risk does not lie in a confusion between products, like in matters relating to trade marks . Where a name is made up of a number of words, any one of them can be isolated and protected if it is sufficiently distinctive and allows consumers to distinguish a given business from others, i.e. of an essential, arbitrary distinctive and new nature having regard to the activity in question, making the undertaking distinguishable in the eyes of the public . This is not the case where the name of the local municipality ("commune") from where the business operates is used . On the other hand, the use of a name consisting only of the name of a municipality is wrongful if it is of such a nature as to create a manifestly unlawful disturbance (trouble manifestement illicite) due to a confusion in the minds of members of the public with the town in question, even though there is no protection for the names of municipalities . 

Usurping or imitating a trade name, and creating a risk of confusion between the common customer-base of undertakings engaged in a similar activity constitutes an act of unfair competition . The courts do no sanction the mere fact of having the same name as another undertaking  but if there is a genuine risk of confusion, imitation may be deemed unfair whether or not it is deliberate . 

Cass. com., 17 July 1984; CA Paris, 27 November 1980.

The corporate name and the trade name are not protected by intellectual property ownership rights and may be reproduced or copied when such reproduction or copies are devoid of any misconduct violating the fair and peaceful enjoyment of the freedom of trade and industry: CA Paris, 14 November 2012, LawLex201200002322JBJ.

Trade name and corporate name

The situation is a little more complicated where the name in question is patronymic (a family name/surname). Everyone has the right to use his or her patronym as a means of distinguishing a business from competitors. The use of the name has to be real and personal, but if it is, the right usually exists even where the name has already been trademarked. The above conditions are met where the holder of the name heads and controls the company bearing the holder's name . Protection is withheld in cases of fraud, where the name is loaned to another under agreement, or where the name is already used by a well-known namesake engaged in a similar activity . There is no possibility of confusion when the namesake, a member of the same family as the holder of a registered trade mark, uses his first name and family name followed by the word “distribution”, especially given that the creation of ready-to-wear clothing is not comparable with the furs, perfumes and luxury products business . It is also not unfair to use the name of a municipality ("commune") in addition to a common phrase, when it refers to the place where the activity is carried out . On the other hand, the apparent use by a company of the name of its sales director, who has been forbidden to make use of his family name for commercial purposes, constitutes unfair competition, insofar as it was clearly done in order to lead customers to believe that they are being directed to a store within the group of the highly-reputed namesake . Similarly, fault may be established where a legal person adopts the name of its founder appended to that of his wife, whereas a very well-known competitor has a very similar name for a similar business activity .

The use of homonyms also raises the question of whether natural persons may prevent the use of a trade name that includes their own name or elements thereof. Case law shows that only deliberate appropriation of well-known names for commercial use may be barred .

Cass. com., 12 November 1992, LawLex200200001691JBJ, on the right for a namesake holding an important position in the company to use their name as the corporate name by adding their first name to the family name; CA Paris, 11 October 1995, on the name bearer heading and running the company; Cass. com., 14 January 2003, LawLex200300000612JBJ, recalls that in principle, every one may use his or her name as a corporate name as long as such use is fair. The transferor who, does not stop using the name “Cabinet Barthélémy” (Barthélémy Agency) and/or the name Barthélémy as agreed in the transfer agreement, as of 1 January 2008, on all documents and media intended for third parties, violates his contractual obligations and creates confusion in the minds of the public with the company carrying out the same activity as a real estate agency, operating under the name “Lionel Barthélémy”, CA Versailles, 2 September 2014, LawLex201400000861JBJ.

Cass. com., 5 November 1985, LawLex200200001931JBJ, finding that the existence of a well-known namesake prevents the use by a trader of his surname in spite of the exercise of separate activities; 21 April 1992, LawLex200200001740JBJ, impossibility for the party having transferred the shares of a company and the name of that company, to later use that family name for a competing company; Cass. com, 15 June 1993, LawLex200200001637JBJ, Cass. com., 12 February 2002, LawLex200200000553JBJ.

CA Paris, 17 October 2007, JurisData nº 2007-349493, finding unfair confusion against the creation of an internet link using the name of the director of a competing company.

CA Dijon, 28 February 2002, LawLex200200006357JBJ; See also CA Nancy, 26 February 2024, LawLex202400001914JBJ: the acquiring company of a business which uses the family name of its founder, making it the primary element of its communications and associating its use with the fact that it is the only carpentry undertaking to be “recognized for more than twenty years” in the field and sector in question, whereas another company, owned by the transferor's brother, has been using this name since 1978, to operate a similar business in a nearby locality, commits an act of unfair competition by creating confusion in the minds of the public.

CA Paris, 24 January 1962, Luynes; Cass. civ., 6 July 1965, Negresco; 13 February 1967, Badoit; 19 December 1967, Savignac; 26 May, 1970, Dop; CA Paris, 7 January 1972, Ala; 19 April 1974; 18 June 1975, Talleyrand; 17 December 1976, Foujita; 3 January 1986, Rotschild; cf. Cass. com., 21 October 1997, LawLex200200001211JBJ, on the lawfulness of the trade mark Duc de Praslin, not used by the Duke of Choiseul at the date of registration.

Protection of a trade name extends to all mediums and uses. Thus a trade name which gives rise to confusion with another cannot continue to be used online, when it has been prohibited for use as a trade name . The party responsible for the confusion can be ordered to change the name subject to penalties. The Court of Cassation considers that such an order constitutes a prohibition on the use of the name in question . The courts have also ruled that the access code to an electronic directory, which is neither a distinctive sign, a registered trade mark, nor a corporate name, is a means of operating a commercial activity. The party having adopted it must be protected against unfair competition resulting from the use of a similar code enabling the user entry to an existing and similar commercial activity .

The same solution applies to domain names . The use of a domain name which incorporates the trade name of a third party to designate a website offering competing products constitutes an act of unfair competition . The name chosen however must be original. This is not the case when the domain name is entirely descriptive as the proprietor may find the same terms on competing sites and in the results of search engines . 

It is also unlawful for an operator to use the name of others to designate a service which allows direct online access to information on its products . Previously, the complicity of paid internet referencing services could also be found in this case. The service provider could render himself guilty of acts of supplying the means of unfair competition when he failed to ensure  that the keywords chosen by the advertiser did not illegally reproduce a trade name, a trade mark or a domain name . Now, in compliance with EU law,  and the LCEN law on confidence in the digital economy (Law No 2004-575 of 21 June 2004 - loi sur la confiance dans l'économie numérique), which regulates the responsibility of hosting providers, an internet referencing service provider cannot, however, be held liable for the data it has stored at the request of the advertiser, unless, having obtained knowledge of the unlawful nature of those data or of that advertiser's activities, it failed to act expeditiously to remove or to disable access to the data concerned . According to the Court of Cassation, an active role by the internet referencing provider regarding knowledge or control of stored data that makes it possible to exclude the benefit of the regime of limited responsibility laid down by the LCEN law, is not established merely due to the fact that the latter has set up its own system of commercial advertisements . Likewise, the use of keywords in the context of the Google AdWords system which uses the corporate name or business name of a competitor is not wrong where the display of the search results in a sidebar entitled “sponsored links” is not likely to make the web-user believe that the products and services referred to in the advertising links originate from the same company  or an economically-linked undertaking . On the other hand, the use of the business name of a competing company in order to trigger the implementation of the Google AdWords system which displays sponsored links relating to the products of that company, but which does not make it possible to identify the advertiser, creates a risk of confusion on the origin of the products marketed .  Google cannot be held liable in respect of its AdWords system for the use by advertisers of keywords corresponding to trade marks, and the corporate names and trade name of a competitor which does not amount to wrongful conduct such as to give rise to compensation for harm suffered .

The reproduction of a third party's domain name is reprehensible like the reproduction of a trade name or a corporate name . Thus, the repurchase, the day after it fell into the public domain, of a domain name that the competitor company with the same name had been using until then, constitutes an act of unfair competition, if it is likely to cause confusion in the minds of the public . This is also the case for the reproduction of the distinctive part of a domain name accompanied by a reference to a competing website in order to create confusion in the public's mind between the domain name and the sign reproducing it , unless the adopted sign is merely the reproduction of generic and usual terms for the type of service in question . Thus, the use of the domain names scootlib.com and scootlib. org does not infringe on the “velib” domain names, whatever their extension, as long as the first syllable(s) to which the consumer generally pays attention are distinct and without phonetic resemblance, and that, from a conceptual point of view, although they have the same construction associating the diminutive of a means of transportation with the suffix “lib” evoking the idea of liberty, they refer to two different types of vehicles, so that the average internet user cannot, when accessing the disputed sites, confuse them with those of the City of Paris or attribute their origin to it .  On the other hand, the use of the terms “comptoir” and “du coton” in a domain name to market bathrobes and slippers is likely to lead the public to believe that there are direct commercial links with the trade name and domain name of a well-known ready-to-wear company, and thus to attribute a common origin to the products respectively offered . The rule also applies to local municipalities, even if the name of the municipalities does not benefit from any protection and the Code of Intellectual Property protects them only against the filing of a trade mark and not of a domain name: using the name of a municipality to operate a website creates a manifestly unlawful disturbance because of the confusion generated in the public's mind .

CA Paris, 7 April 1995, LawLex200200001464JBJ, on the extension of protection of the trade name to all media liable to be used; but see TGI Paris, 7 September 2001, LawLex200200000466JBJ, use of an identical name for a website and a Minitel service (French pre-World Wide Web online service).

Trade name and internet 

Commercial documents, such as catalogs, product references, and headed paper allow undertakings to establish their brand image. The copying of such documents can constitute a means for third parties to divert customers by the appropriation of a competitor's brand image . In effect, although it may be justified for the characteristics of certain products to be the same, the slavish copying of documents presenting those products to the public is wrongful . The appropriation can take several forms. The copying of a competitor's catalog has been sanctioned by the courts on a number of occasions . Confusion can also result from the use of references identical to those used by a competing undertaking , or using the advertising signs of a competitor and hiding the commercial names . Any risk of confusion can be avoided where sales brochures are clearly differentiated  or where the terms of sale of an operator are as advantageous as those of its competitor .

Such appropriation can also be the result of a presentation of the products of the competitor or of statements to customers which give the impression that the two companies are in fact one: CA Paris, 27 May 1992, LawLex200200001730JBJ; Cass. com., 15 June 1993, LawLex200200001637JBJ

Commercial documents 

An undertaking may also seek to distinguish itself by its exterior presentation; the latter may be a decisive element for the customer who may, in the event of imitation, confuse traders. However, the courts have been fairly strict in the matter. The exterior decor must be sufficiently characteristic and not result from what is currently in vogue . Further, the similarity must be such as to create a risk of confusion and divert customers. This is especially so when a direct competitor adopts the visual references of a competitor which is very well-known for its store front, documents and commercial vehicles . Interior design may also play some part in identifying the stores of a group in the minds of customers but as it is generally associated with other distinctive signs (logo, emblem etc.) and other attractive features (e.g. after-sales service), it is not in itself a decisive element in terms of customer choice. Only an identical reproduction of the interior design is therefore unlawful as the risk of customer poaching can only exist if the undertakings are located in the same catchment area .

Nancy, 9 December 2002, LawLex200300001878JBJ, excluding confusion when the exterior sign is sufficiently distinct from that of the competitor, even if the interior is still similar in terms of concept and  atmosphere to that of the competitor and the former franchisor. But see T. com. Lyon, 6 September 2002, LawLex200300001673JBJ, finding that the applicant to a franchise network creates a confusion by keeping the same the layout and the organization of the store required to integrate the network.

Exterior decor  

An undertaking's advertising policy is obviously an important identifying element. Imitation in this area normally concerns slogans. The general rule is that advertising ideas are not capable of appropriation . Indeed, an advertising slogan is only capable of being the basis of a suit for unfair practices where there is confusion or a risk of confusion and proof of fault on the part of the competitor is brought to bear . Likewise, similarities between the project of a communications agency pre-selected in the context of a call for tenders and with which relations were not ultimately pursued and the final advertising campaign released do not in themselves demonstrate an act of unfair competition on the part of the advertiser, when the two undertakings worked on the basis of the same instruction . Moreover, the slogan must be original in nature to be protected . If the similarities between the publicity slogans are a result of the adoption of similar promotional methods and elements and formulas necessary for its description, there is no risk of confusion . However, the appropriation of an advertising idea can be considered an aggravating factor in a finding of confusion . The abusive use of the term “fresh compotes” in order to create confusion with the products containing the indication that such products should be kept refrigerated is therefore unfair . Likewise, the slavish copying of the advertising tools of others , advertising signs  or labels  belonging to a competitor constitutes a wrongful act. Lastly, the use by a former distributor having become a garage owner of the term “specialist” of the brand, which was sanctionable over a long period of time, now only constitutes a fault if the undertaking in question cannot bring evidence of the reality of that description, or if it leads to confusion with actual members of the network . This would not be the case of course if the former dealer continues to use the network logo or trade mark .
