Tunisia's Court of Cassation (Cour de Cassation), the highest court in the Tunisian judicial hierarchy, delivered a precedent-setting judgment on the scope of well-known trademark protection and the doctrine of unfair competition under Tunisian law. The dispute arose between a globally recognised French luxury fashion house and a Tunisian limited liability company that manufactured and sold handbags bearing trade dress — including distinctive patterns, colour combinations, and logo placement — that closely imitated the French house's registered and well-known marks. The French claimant had not registered all of its trademarks with the Tunisian National Institute for Standardisation and Industrial Property (INNORPI) at the time of the alleged infringement. The Court of Cassation quashed the Court of Appeal's judgment, which had dismissed the claim on the ground that only locally registered marks enjoy protection, and held that well-known foreign trademarks benefit from protection under Article 6bis of the Paris Convention for the Protection of Industrial Property, as incorporated into Tunisian law through Law No. 2001-36 of 17 April 2001 on the Protection of Industrial Property and through Tunisia's obligations under the TRIPS Agreement. The Court further held that the Tunisian manufacturer's systematic imitation of the French house's overall commercial presentation — including store layout, packaging, and visual merchandising — constituted unfair competition under Articles 36 and 37 of the Tunisian Commercial Code, entitling the claimant to damages even for unregistered elements of trade dress.
Maison Lumière SA, a French luxury fashion house headquartered in Paris and founded in 1923, has marketed its handbags and leather goods globally for over a century. Its signature "ML" monogram pattern and diamond-quilted leather design have been registered as trademarks in multiple jurisdictions, including through international registrations under the Madrid System designating several Arab states. However, at the relevant time, Maison Lumière had registered only its word mark "MAISON LUMIÈRE" in Tunisia through INNORPI. Its monogram pattern and quilting design marks had not been separately registered in the Tunisian trademark registry, although the house's products had been sold through authorised retailers in Tunis and Sousse for over twenty-five years and were widely advertised in Tunisian print and digital media. In 2022, Société El-Manara de Maroquinerie SARL, a Tunisian leather goods manufacturer based in the Mghira industrial zone near Tunis, began producing and distributing handbags under the brand name "LUXIÈRE" that replicated the diamond-quilting pattern, the interlocking monogram motif, the gold-chain strap design, and the distinctive burgundy interior lining characteristic of Maison Lumière's bestselling product line. The handbags were sold at approximately one-tenth the price of the authentic products through El-Manara's own retail outlets in Tunis, Sfax, and Sousse, and through an e-commerce website. Maison Lumière commenced proceedings before the Tunis Court of First Instance, seeking an injunction against further sales, the seizure and destruction of infringing goods, and damages of TND 2.8 million for trademark infringement and unfair competition. The Court of First Instance granted partial relief, issuing an injunction but limiting damages to TND 400,000 on the basis that only the word mark was locally registered. On appeal, the Tunis Court of Appeal went further and dismissed the claim entirely, holding that (i) unregistered marks — even well-known ones — enjoy no protection under Tunisian law, and (ii) trade dress imitation does not constitute unfair competition absent a registered design right. Maison Lumière appealed to the Court of Cassation on points of law.
The Court of Cassation identified three principal questions of law: (1) Whether Article 6bis of the Paris Convention — which obliges member states to protect well-known trademarks even absent local registration — is directly applicable in Tunisian courts, or whether it requires domestic implementing legislation beyond the general reference in Law No. 2001-36; (2) Whether trade dress, store layout, packaging, and overall commercial presentation — elements not individually registered as trademarks or industrial designs — can form the basis of an unfair competition claim under Articles 36 and 37 of the Tunisian Commercial Code; and (3) What quantum of proof is required to establish that a mark is "well-known" in Tunisia — specifically, whether international reputation plus some local commercial presence suffices, or whether the mark must be known to the general Tunisian public rather than merely the relevant consumer segment.
The Court of Cassation quashed the Court of Appeal's judgment and remitted the case to a differently constituted panel of the same court, holding that:
(1) Well-known trademarks are entitled to protection in Tunisia even in the absence of local registration. The Court held that Article 6bis of the Paris Convention, read together with Articles 1 through 4 of Law No. 2001-36 and Tunisia's obligations under the TRIPS Agreement (ratified by Law No. 95-7 of 23 January 1995), forms part of the Tunisian legal order and is directly invocable before Tunisian courts. The Court distinguished between ordinary trademarks — which require registration with INNORPI to be enforceable — and well-known marks, which enjoy a sui generis protection rooted in international treaty obligations. The Court noted that the Paris Convention has constitutional rank in Tunisia by virtue of Article 20 of the 2014 Constitution, which provides that duly ratified international treaties prevail over domestic statutes. The Court of Appeal's finding that only registered marks are protected was therefore an error of law.
(2) The systematic and deliberate imitation of a competitor's overall commercial presentation — including elements not individually registered as intellectual property rights — may constitute unfair competition (concurrence déloyale) under Articles 36 and 37 of the Commercial Code where the cumulative effect of the imitated elements creates a likelihood of confusion among consumers. The Court endorsed a "totalité des circonstances" (totality of circumstances) approach, holding that courts must assess whether the defendant's acts, viewed as a whole, amount to a parasitic exploitation of the claimant's commercial reputation and investment, rather than analysing each imitated element in isolation. The Court found that El-Manara's conduct — which extended beyond the handbags themselves to include similar store layout, gold-toned packaging, and product-naming conventions that evoked Maison Lumière's iconic product lines — went beyond lawful competition and constituted an intentional misappropriation of commercial goodwill.
(3) To establish that a mark is "well-known" within the meaning of Article 6bis of the Paris Convention, the claimant must demonstrate that the mark enjoys a significant degree of recognition among the relevant sector of the public in Tunisia — not the general public at large. The Court held that evidence of substantial sales volumes in Tunisia, long-standing local advertising, unsolicited media coverage in Tunisian publications, and consumer survey evidence demonstrating spontaneous recognition among purchasers of luxury leather goods in the Tunis market — taken together — satisfied the threshold for well-known mark status. The Court explicitly declined to adopt the higher standard of "general public recognition" that some Arab jurisdictions have applied, noting that such a standard would effectively deny protection to specialised or luxury goods whose consumer base is definitionally narrower.
This ruling is the most consequential intellectual property decision issued by Tunisia's Court of Cassation since the 2001 reforms to the industrial property framework. It resolves a long-standing ambiguity in Tunisian law regarding the enforceability of well-known foreign trademarks absent local registration — an ambiguity that had been exploited by local manufacturers to produce "lookalike" luxury goods with relative impunity. The decision significantly strengthens Tunisia's IP enforcement regime and represents an important step toward compliance with the EU-Tunisia Association Agreement (signed 1995, entered into force 1998) and the ongoing negotiations for an Accord de Libre-Échange Complet et Approfondi (ALECA), under which the European Union has consistently pressed Tunisia to raise its IP protection standards. For international brand owners, the ruling provides a clear road map for enforcing well-known mark rights in Tunisia without the need for exhaustive local registrations. The "totality of circumstances" approach to unfair competition — borrowed from French jurisprudence but now firmly anchored in Tunisian law — offers a flexible doctrinal tool for combating parasitic copying that falls short of trademark counterfeiting. IP practitioners in Tunis expect the decision to trigger a wave of enforcement actions by international luxury, cosmetics, and consumer goods brands that have long viewed Tunisia as a jurisdiction of weak IP remedies. The ruling also carries significance for other Maghreb jurisdictions — particularly Algeria and Morocco — whose courts have grappled with similar questions and often look to Tunisian and French case law for persuasive authority.
"The protection of well-known marks is not a discretionary concession that states may grant or withhold at their convenience. It is a binding obligation under the Paris Convention, to which Tunisia acceded in 1883 and whose provisions are an integral part of Tunisian public order. A trademark registration system cannot be allowed to become an instrument of parasitism — a mechanism by which local enterprises profit from the reputation and investment of foreign mark holders while evading the substantive obligations that international law imposes. The Paris Convention does not permit a state to say to the world's trademark owners: 'your marks are protected here, but only if you navigate our domestic registration process for each and every mark.' That would empty Article 6bis of all meaning and transform the Convention into a mere invitation to register rather than a guarantee of protection." — President of the Chamber, Justice Moncef Bouzayane
