CJEU Rules That Dates Suggesting False Heritage Can Mislead Consumers

In Short

The Situation:
In Case C-412/24, the Court of Justice of the European Union ("CJEU") took up the question of whether including a date in a trademark can render such trademark deceptive. The case stemmed from a divergence between French courts and the European Union Intellectual Property Office ("EUIPO") over whether false claims about a proprietor's history and accumulated know-how fall within the scope of this ground of invalidity.

The Development: The CJEU held that a number in a trademark, where the relevant public may read it as the year a business was established, can make the mark deceptive—particularly if it falsely implies a depth of long-standing know-how that simply does not exist.

Looking Ahead: The decision hands brand owners and competitors a more robust basis for challenging marks built on fabricated—or no longer accurate—history, with particular force in the luxury sector. Going forward, businesses should take care to ensure that any date appearing in a mark genuinely reflects the brand's corporate origins.

Background of the Decision


The dispute pitted two competitors in the French luxury leather goods market against one another. The applicant, a company formed in 2009, had acquired a trademark from a former sole shareholder of a historic business that had ceased operations in 1992. Building on this acquisition, the applicant registered marks in 2011 containing the word elements "Paris 1717" for leather goods including handbags, trunks, and travelling bags.


A competitor challenged these marks before the French courts, arguing that the element "1717" created a false impression of centuries of accumulated craftmanship—when in reality, no operational link existed between the applicant and the historic business.


The Paris Court of Appeal agreed, finding the marks deceptive. In its view, the word elements "Paris 1717" evoked the place and date of establishment of the historic business and were apt to lead consumers into believing that there had been an unbroken continuity of operations since 1717. More critically, the court reasoned that consumers would assume the original undertaking's know-how had been transmitted to the applicant—an association that, for the relevant public, served as a guarantee of the quality of the goods to be sold by the applicant covered by those marks.


On further appeal, the French Court of Cassation (Cour de cassation) identified a divergence between the domestic courts' approach and that of the EUIPO. It referred a preliminary question to the CJEU asking, in substance, whether a mark incorporating a founding date may be considered deceptive where it falsely implies long-standing know-how and prestige that do not actually exist. At the heart of the referral was a threshold question: Can false information about a proprietor's history—as distinct from a characteristic of the goods themselves—render a trademark deceptive and therefore invalid?


Key Aspects of the Ruling


Legal Framework


Article 3(1)(g) of EU Directive 2008/95/EC provides that trademarks "which are of such a nature as to deceive the public, for instance as to the nature, quality or geographical origin of the goods or service" shall not be registered or, if already on the register, shall be liable to be declared invalid.


That Directive has since been repealed and replaced by Directive 2015/2436, effective 15 January 2019, with the equivalent provision now appearing in Article 4(1)(g). While the new directive did not apply to this case given the timing of the underlying facts, the CJEU's reasoning carries equal relevance to proceedings brought under the current framework.


The CJEU's Response and Reasoning


In its decision of 26 March 2026, the CJEU began by reaffirming a well-established principle: Trademark deceptiveness must relate to characteristics of the goods, not those of the proprietor. A mark cannot be invalidated simply because it conveys misleading information about its owner—say, about the owner's history or founding date—unless that information shapes how consumers perceive the goods themselves.


But the court went further. It recognized that in certain sectors—luxury goods market chief among them—characteristics of the proprietor can become inextricably linked with characteristics of the goods. Where a trademark includes a number that the relevant public may read as a year of establishment, it can evoke deep-rooted know-how and expertise. In the luxury sector, such perceived heritage contributes to a product's allure and prestigious image, which in turn forms part of its quality. It follows that if a mark falsely suggests centuries of accumulated skill where none exists, the deception touches on the quality of the goods and may furnish grounds for invalidity.


The CJEU stopped short of laying down a bright-line rule, opting instead for a case-by-case approach. The assessment falls to national courts, which must determine, in light of all the circumstances, whether the relevant public perceives the number as a founding year and, if so, whether that perception evokes know-how conferring a guarantee of quality and prestige. National courts are directed to examine each mark as a whole, considering, among other things, accompanying elements such as a place name and the overall message the mark conveys to consumers.


Conclusion


The upshot of this ruling is clear: In the luxury sector, in particular, where heritage and tradition can carry significant weight with consumers, brand owners cannot treat historical dates as mere marketing embellishments. Any gap between a mark's claimed origin and the brand's actual history may now open the door to invalidity on the grounds of consumer deception.

Three Key Takeaways

  1. In heritage-sensitive sectors—which could include businesses beyond luxury goods—the allure and prestigious image of a product are treated as part of its quality. A number used in a trademark that suggests a founding year—and implies expertise that does not exist—may therefore be found deceptive.
  2. Competitors now stand on firmer ground when challenging EU trademarks that invoke unsubstantiated heritage claims.
  3. Businesses operating in heritage-sensitive markets would be well advised to audit their branding and confirm that any historical references are backed by genuine, demonstrable links to past operations and expertise.
