In September 2025, the Beijing Intellectual Property Court rendered a civil judgment of first instance in the case concerning disputes over trademark infringement and unfair competition among Thermos (China) Housewares Co., Ltd. (the “Plaintiff”), Thermos Technology (Tianjin) Co., Ltd. (“Thermos Technology”), Zeng Dong, and Beijing Catdog Planet Pet Service Co., Ltd. (collectively, the “Defendants”). The case focuses on a range of issues, including whether the registered trademark No. 688940 for “膳魔师” (Thermos in Chinese) can be granted cross-category protection as a well-known trademark; whether the Defendants’ use of their registered “膳魔师” trademark on pet food under Class 31 still constitutes infringement; whether using “膳魔师” as a corporate trade name constitutes unfair competition; and whether the shareholder of a single-shareholder company shall bear joint and several liability for the company’s debts.
The Court ultimately determined that the registered trademark “膳魔师” involved in the case had attained well-known trademark status on vacuum flasks under Class 21. The Court found that Defendant Thermos Technology’s use of signs such as “膳魔师” and “SHANMOSHI” on pet food constituted the reproduction and imitation of a well-known trademark, which was sufficient to mislead the public. Concurrently, its use of “膳魔师” as its corporate trade name constituted unfair competition. Consequently, the Court ordered Thermos Technology to cease the infringement, stop using its corporate name containing the character string “膳魔师”, and pay damages for economic losses and reasonable expenses totaling RMB 520,000. Furthermore, as the sole shareholder of the single-shareholder company, Zeng Dong failed to prove that the company’s property was independent of his personal property, and was thus held jointly and severally liable for the liquidation of the debt.
The judgment in this case reflects the unequivocal stance of intellectual property adjudication in curbing malicious free-riding, preserving the source-identifying function of trademarks, and maintaining the order of commercial goodwill. It also provides a valuable judicial paradigm for addressing complex infringements characterized by the overlay of cross-category registration and corporate trade names.
I. Factual Background The Plaintiff in this case, Thermos Housewares, is the principal operating entity of the “THERMOS/膳魔师” brand in the Chinese market. The involved trademark No. 688940 for “膳魔师” was approved for registration in 1994, designated for use on goods under Class 21 including vacuum flasks, thermoses, and stainless steel cookware, and remains valid through renewal until 2034. The judgment established that since entering the Chinese market in 1995, the Thermos brand has long sold relevant products through channels such as online e-commerce platforms, offline department store counters, and specialty stores, while continuously conducting advertising campaigns, media promotions, and brand collaborations. Given its substantial sales volume, extensive market coverage, promotional investment, and history of administrative and judicial protection, the involved trademark has acquired a high level of reputation on goods such as vacuum flasks. It had previously been recognized as a well-known trademark in relevant rulings and decisions issued by the Trademark Office of the State Administration for Industry and Commerce, the Beijing High People’s Court, and the National Intellectual Property Administration.
Defendant Thermos Technology, formerly known as Tianjin Wancheng Chuangxin Technology Co., Ltd., changed its name to its current form in March 2017. In April of the same year, it applied for the registration of trademark No. 23551067 for “膳魔师”, which was approved for use on goods under Class 31, including pet food and pet beverages. Thereafter, the Defendant utilized signs such as “膳魔师” and “SHANMOSHI” on pet food packaging and across online channels such as Taobao, Tmall, Douyin, WeChat, and 1688, and promoted and sold its products under names such as “膳魔师宠物食品” (Thermos Pet Food) and “膳魔师·宠物食品”. The Plaintiff asserted that the aforementioned acts constituted the reproduction and imitation of its well-known trademark, sufficient to cause public misconception or create a specific association, thereby constituting trademark infringement and unfair competition. Conversely, the Defendants argued that their actions constituted lawful use of their registered Class 31 trademark, that the categories of goods were distinctly different so as not to cause confusion, and that the corporate name was used in the ordinary course of business.
II. Focus of Disputes This case primarily involves four core disputes: first, whether it is necessary and feasible to recognize the involved “膳魔师” trademark as a well-known trademark in this case; second, whether the Defendant’s use of a registered trademark automatically precludes civil liability for infringement, particularly where the registration has exceeded five years, and whether the owner of a well-known trademark may still seek an injunction against such use; third, where pet food and vacuum flasks do not constitute similar goods, whether the use of identical or similar signs is sufficient to constitute cross-category infringement of a well-known trademark; and fourth, whether using another party’s well-known trademark as a corporate trade name constitutes confusing unfair competition, and whether a natural person shareholder should bear joint and several liability.
III. Key Points of Adjudication (1) The Necessity and Factual Basis for the Recognition of a Well-Known TrademarkThe Court first examined the necessity of recognizing the well-known trademark. Pursuant to Article 14 of the Trademark Law, the recognition of a well-known trademark shall govern by the principles of “case-by-case recognition, passive protection, and necessity-driven recognition.” In this case, the accused goods are pet food, which are neither identical nor similar to the vacuum flasks, thermoses, and other goods for which the involved trademark is registered. If the Plaintiff seeks cross-category protection, it must rely on the well-known trademark system as its normative basis; hence, it was necessary for the Court to determine whether the involved trademark was well-known. Factoring in the duration of registration and use, sales volume, scope of promotion, market reputation, and prior protection history of the involved trademark, the Court determined that at the time Thermos Technology applied for trademark No. 23551067, the involved trademark had already become widely known to the relevant public within the territory of China and constituted a well-known trademark on vacuum flasks under Class 21. This finding reflects the functional orientation of the well-known trademark system: it does not confer an abstract honor upon a trademark, but rather provides special protection to remedy the inadequacy of ordinary confusion-based protection in scenarios involving cross-category misleading, dilution, or the improper exploitation of commercial goodwill.
(2) The Boundaries of the Registered Trademark DefenseA core dispute in this case is whether the Defendant could preclude liability for infringement on the grounds that it owned a registered trademark under Class 31. The Court did not mechanically adopt the defense that “registration equates to legality.” Instead, it applied a systemic interpretation combining Article 11 of the Judicial Interpretation on Civil Cases Involving Well-Known Trademarks and Paragraph 1 of Article 45 of the Trademark Law. The Court held that Article 45, Paragraph 1 of the Trademark Law, as referenced in Article 11 of the Judicial Interpretation, encompasses not only the five-year limitation period for invalidation declarations but also the exceptional rule dictating that “in cases of malicious registration, the owner of a well-known trademark is not subject to the five-year limitation.” Otherwise, a malicious registrant might acquire improper benefits against the owner of a well-known trademark simply through the passage of time, which would subvert the objective of the special protection system for well-known trademarks.
This interpretive path effectively harmonizes the relationship between the stability of registered trademarks and the substantive protection of well-known trademarks. Although the exclusive right to use a registered trademark carries the effect of public notice and stability of rights, it cannot serve as a lawful justification for maliciously free-riding on another’s commercial goodwill. Even if a subsequently registered trademark is valid in form, if its registration involves the malicious reproduction or imitation of a prior well-known trademark, and its actual use is sufficient to mislead the public or damage the interests of the well-known trademark owner, the People’s Court may still issue an injunction against its use in civil infringement proceedings. This adjudication neither directly invalidates the legal status of the registered trademark nor avoids a substantive examination of the specific act of use at the liability phase, thereby preventing the absolutization of the registered trademark defense.
(3) Methods for Determining Bad FaithIn evaluating bad faith, the Court primarily inferred the subjective state of the actor from objective facts. “膳魔师” is not an everyday generic term, but rather a highly distinctive coined sign, making it highly improbable for other market entities to coincidentally select an identical sign. Furthermore, prior to the Defendant’s application for the “膳魔师” trademark under Class 31, the involved trademark had already achieved a high reputation on vacuum flasks, which are daily consumer goods widely encountered by the general public, meaning the Defendant knew or should have known of the trademark. Coupled with the fact that the Defendant had applied for multiple “膳魔师”-related trademarks under Class 5 and Class 31, as well as signs such as “米奇膳魔师” (Mickey Thermos), the Court inferred that the Defendant possessed the subjective bad faith to free-ride on the reputation of another party’s famous trademark. This determination embodies the rule of thumb applied in identifying trademark bad faith: the stronger the distinctiveness of a sign, the higher the prior reputation, the closer the subsequent sign, and the more the application layout manifests characteristics of reproduction and expansion, the less room remains for the actor to assert good faith.
(4) Establishments of Cross-Category Trademark InfringementRegarding the determination of trademark infringement, the Court conducted its analysis pursuant to Paragraph 3 of Article 13 of the Trademark Law. This provision governs the protection of well-known trademarks on non-identical or dissimilar goods, requiring that the subsequently used sign constitutes a reproduction, imitation, or translation, is sufficient to mislead the public, and is likely to prejudice the interests of the registrant of the well-known trademark. In this case, the Defendant utilized signs such as “膳魔师” and “SHANMOSHI” in scenarios including pet food packaging, product links, store profile pictures, promotional videos, WeChat official accounts, mini-programs, and 1688 shop descriptions. Such acts serve the function of identifying the source of goods and constitute trademark-use. The aforementioned signs are highly similar to the involved trademark in textual composition, pronunciation, and corresponding correlation. Although pet food and vacuum flasks do not constitute similar goods, both target the daily consumer sector, and their relevant public overlaps. Given the high reputation of the involved trademark, the Defendant’s acts of use are likely to lead the public to mistakenly believe that a licensing, collaborative, affiliated-corporate, or brand-extension relationship exists between the pet food and the Thermos brand. This unfairly exploits the market reputation of the well-known trademark and dilutes its distinctiveness, thereby constituting trademark infringement.
This case does not broaden the cross-category protection of well-known trademarks into an all-category protection. The core of the Court’s assessment remained centered on whether a “considerable degree of association” was formed, whether the public was misled, and whether it resulted in the dilution of distinctiveness or the unfair exploitation of commercial goodwill. Although pet food and vacuum flasks differ in their functions and uses, the Defendant did not merely make incidental reference to “膳魔师”; rather, it continuously, prominently, and systematically utilized the sign in contexts identifying the source of goods, which was sufficient to break through the cognitive isolation formed by the differences in product categories.
(5) Unfair Competition Evaluation of Corporate Trade Name ConfusionRegarding the act of using the corporate name, the Court, pursuant to Item 4 of Article 6 of the Anti-Unfair Competition Law and relevant judicial interpretations, determined that Thermos Technology’s adoption of “膳魔师”—which is identical to the involved registered trademark—as its corporate trade name and its use thereof in business activities was likely to mislead the public into believing that a licensing, affiliation, or other specific connection existed between it and Thermos Housewares. This damaged the rights holder’s competitive advantage and constituted confusing unfair competition. This finding addresses the complex free-riding pattern frequently observed in practice, namely the “overlay of trademark registration and trade name usage.” Compared to a standalone review of trademark use, the Anti-Unfair Competition Law enables a supplementary evaluation from the perspectives of the overall use of commercial signs, confusion over the identity of market entities, and the improper misappropriation of transactional opportunities. The Court’s order to cease using the corporate name containing the character string “膳魔师” is a direct rectification of such trade name confusion.
(6) Joint and Several Liability of the Shareholder of a Single-Shareholder CompanyConcerning the distinction between liability for infringement and liability under the Company Law, the Court rejected the argument that the natural person and the company constituted joint tortfeasors. However, pursuant to the rules governing the burden of proof for property independence in a single-shareholder limited liability company, the Court determined that as the sole shareholder of Thermos Technology, Zeng Dong failed to prove that the company’s property was independent of his personal property, and he must therefore bear joint and several liability for the liquidation of the company’s debts. This adjudication distinguishes “joint tort liability” from the “joint and several liability of a shareholder in a single-shareholder company”: the former focuses on proving the natural person’s participation in the infringing act, whereas the latter arises from a special burden of proof regarding the independence of the corporate personality. This distinction helps prevent the conflation of liability evaluations and reinforces the compliance obligations of shareholders in single-shareholder companies.
Comment From the perspective of institutional significance, this case presents a relatively complete practical application of the rules governing the cross-category protection of well-known trademarks. First, it confirms that a subsequently registered trademark does not constitute an absolute defense; those who maliciously register and use a well-known trademark may still be enjoined from use in civil infringement cases. Second, it emphasizes that the key to well-known trademark protection lies not in formal differences between product categories, but in whether the relevant public will form a specific association among the signs, products, usage scenarios, and market perceptions, and whether such an association is sufficient to dilute the distinctiveness of the well-known trademark or unfairly exploit its commercial goodwill. Third, it regulates the use of corporate trade names through the Anti-Unfair Competition Law, responding to complex free-riding acts where trademark infringement and trade name confusion are intertwined. Finally, it implements the liability of shareholders in single-shareholder companies through rules of the Company Law, enhancing the practical efficacy of judgment enforcement and damage remedies.
From the perspective of judicial methodology, this case reflects the integration of systemic interpretation and the balancing of interests in intellectual property adjudication. The Court did not apply any single provision in isolation, but instead established an interpretive chain across Articles 13, 14, 45, 57, and 63 of the Trademark Law, Articles 6 and 17 of the Anti-Unfair Competition Law, and Article 23 of the Company Law. In particular, its handling of the relationship between the malicious registration exception under Article 45 of the Trademark Law and Article 11 of the Judicial Interpretation Involving Well-Known Trademarks reflects a judicial approach that rectifies formal appearances of rights through substantive justice. For market entities that maliciously squat, hoard, or engage in cross-category free-riding on famous trademarks, this case sends a clear signal: a registration certificate cannot automatically launder a malicious source, and trademark use that exceeds the boundaries of good faith remains subject to civil judicial scrutiny.
For the development of intellectual property adjudication, this case demonstrates the synergistic functions of the Trademark Law, the Anti-Unfair Competition Law, and the Company Law in disputes involving complex commercial signs through a comprehensive chain of rule application, offering significant value as a reference for similar cases and providing meaningful practical insights.
The Court ultimately determined that the registered trademark “膳魔师” involved in the case had attained well-known trademark status on vacuum flasks under Class 21. The Court found that Defendant Thermos Technology’s use of signs such as “膳魔师” and “SHANMOSHI” on pet food constituted the reproduction and imitation of a well-known trademark, which was sufficient to mislead the public.
