1. Zhen Kung Fu Trademark Invalidation Case
The China National Intellectual Property Administration (CNIPA) ruled on an invalidation request filed by Bruce Lee Enterprises regarding the “Kungfu and Design” and “
” trademarks (“Disputed Marks”). The ruling determined that: The Disputed Marks are nearly identical to the image and classic poses of Bruce Lee, a renowned Chinese martial arts master. Using this trademark for designated services would likely cause consumers to misidentify the source of services, thus violating Article 10, Paragraph 1, Item 7 of the Trademark Law (deceptive and likely to mislead the public). The Disputed Marks were declared invalid. The plaintiff, Zhen Kung Fu Catering, disagreed with this ruling and in June 2024, the Beijing Intellectual Property Court issued a judgment dismissing Zhen Kung Fu’s appeal. Zhen Kung Fu petitioned to the Beijing High Court, which in October 2024 made a final judgment dismissing the petition and upholding the CNIPA’s verdict.
The Beijing High Court held that: The Disputed Marks consist of the text “Kungfu” and a half-body figure image. Bruce Lee was a famous Chinese kung fu film star, martial arts master, and globally renowned promoter of Chinese kung fu, honored as the “King of Kung Fu.” Before the Disputed Marks’ registration date, Bruce Lee was already a household name with extremely high recognition and widespread influence. Considering the survey results and other evidence submitted by Bruce Lee Enterprises, and the common perception of the public and consumers, when the Disputed Marks are used on designated services, the public could easily associate the half-body figure resembling Bruce Lee’s classic image with Bruce Lee himself, thus mistakenly believing that the relevant services have a specific connection with Bruce Lee. Moreover, evidence from book excerpts submitted by Bruce Lee Enterprises shows that the designer of the Disputed Marks’ image mentioned “Bruce Lee” and “Kung Fu Dragon” multiple times in his writings, claiming to have seized an excellent image resource and using the Kung Fu Dragon image to convey the core value of the Zhen Kung Fu brand to leave a memorable impression on consumers. Besides the Disputed Marks, Zhen Kung Fu Catering has registered dozens of other trademarks related to Bruce Lee’s image. Zhen Kung Fu Catering explicitly acknowledged during the first instance trial that their brand image was created with reference to Bruce Lee’s image. This establishes that Zhen Kung Fu Catering subjectively intended to allow relevant consumers to be confused or misled about the source of services. Considering these factors, the first-instance judgment and the contested ruling correctly determined that the Disputed Marks violated Article 10, Paragraph 1, Item 7 of the 2001 Trademark Law. Zheng Kung Fu Catering’s appeal arguments lack factual and legal basis and were not supported by the court.
The Disputed Marks violated Article 10, Paragraph 1, Item 7 of the 2001 Trademark Law, an absolute prohibition clause, making its registration application illegal. The subsequent publicity, use, and recognition of the Disputed Marks are not factors to be considered when reviewing whether its registration should be maintained. Therefore, Zhen Kung Fu Catering’s appeal claims could not be established and were not supported by the court.
2. Michelin Trademark Invalidation Case
The CNIPA issued a ruling on an invalidation request filed by Michelin Group Corporation against the “Meiqilin Technology MECHELEN M and Design” trademark (Disputed Mark). The ruling determined that the Disputed Mark differed significantly from Michelin’s claimed well-known “Miqilin in Chinese” and “Michelin” trademarks in terms of text composition, pronunciation, visual effect, etc., and did not constitute reproduction or imitation of Michelin’s trademarks. Furthermore, the “playing cards” and other goods designated by the Disputed Mark differ greatly in function, purpose, sales venues, and consumer base from Michelin’s well-known “tire” products. The registration of the Disputed Mark would not mislead the public or harm Michelin’s interests, thus not violating Article 13, Paragraph 3 of the Trademark Law (well-known trademark protection against unauthorized use). The ruling maintained the registration of the Disputed Mark for goods other than “building blocks (toys); toy cars; intelligent toys.”
Michelin disagreed with this ruling and filed a lawsuit with the Beijing Intellectual Property Court, which dismissed Michelin’s claims. Michelin then appealed to the Beijing High Court.
After review, the Beijing High court determined that: Based on evidence submitted by Michelin, including certification records of cited trademark, prior adjudications, prior administrative judgment documents, media reports about Michelin’s products, sponsored events, Michelin food and tourism guides, business revenue, advertising expenditures, and facts established in Administrative Judgments, it can be proven that prior to the Disputed Mark’s application date, through Michelin’s continuous use and extensive promotion, cited trademarks “Miqilin in Chinese” and four “MICHELIN” had formed a stable corresponding relationship and had become widely known to the relevant public in China for “tires,” reaching the level of a well-known trademark.
The disputed trademark “Meiqilin Technology MECHELEN M and image” is a text-image combination trademark, with “Meiqilin in Chinese” and “MECHELEN” as its distinctive identifying parts. These distinctive parts do not form a clear distinction from cited trademarks in terms of text composition, pronunciation, overall visual effect, and meaning. Both cited trademarks “Miqilin in Chinese” and “MICHELIN” are coined words, and in the absence of a reasonable explanation from Meiqilin for including terms similar to “Miqilin in Chinese” and “MICHELIN” in the Disputed Mark, the Disputed Mark constitutes reproduction and imitation of cited trademarks.
The higher the recognition of a well-known trademark, the more easily it leads to dilution or “free-riding” damage, and therefore the more it should receive anti-dilution protection. Thus, the scope of cross-category protection for well-known trademarks is related to their recognition and distinctiveness; the higher the recognition and stronger the distinctiveness, the broader the scope of cross-category protection should be.
Although the remaining goods designated by the Disputed Mark (excluding “building blocks (toys); toy cars; intelligent toys”) differ from the “tires” product for which cited trademark is well-known in terms of function, purpose, consumer base, and production departments, based on the well-known status and high recognition of cited trademarks for “tires,” the coexistence of the Disputed Mark with cited trademarks could easily lead relevant consumers to believe that there is some connection between the Disputed Mark and cited trademarks or Michelin, thereby weakening the distinctiveness of cited trademarks or improperly utilizing their market reputation, potentially damaging Michelin’s interests in its well-known trademarks. Therefore, the registration of the Disputed Mark for goods other than “building blocks (toys); toy cars; intelligent toys” violated Article 13, Paragraph 3 of the Trademark Law and should be invalidated.

On March 14, 2026, the China National Intellectual Property Administration (CNIPA) released the "Guidelines for Patent Applications Involving Standards" (hereinafter referred to as the "Guidelines") on its official website. The release aims to address the increasing number of patent applications involving standards and the heightened societal attention on this area, providing applicants with policy interpretations and practical guidance within the current patent legal framework. While the Guidelines focus on the telecommunications field, the principles and strategies discussed therein may also serve as a reference for other technical fields. The full text is divided into four chapters. Starting from foundational concepts, it elaborates on the synergistic relationship between standards and patents, with key recommendations focusing on filing and drafting strategies. This article will briefly summarize the main content of the Guidelines and offer certain perspectives and operational recommendations formed through our practice.
Based on the latest 2025 revision of China's Patent Examination Guidelines, this paper employs empirical analysis of typical cases to delve into the "three-step examination framework" for assessing the subject matter eligibility of AI-related inventions: ethical examination, the exclusion of rules and methods for mental activities, and the determination of a technical solution. Among these, of central importance is the determination of a technical solution as to whether algorithmic features are substantively integrated with technical features, thereby jointly constituting technical means that apply the laws of nature to solve a technical problem and achieve a technical effect conforming to the laws of nature. Furthermore, through a comparative analysis with the USTPTO’s Mayo-Alice two-step test, this paper reveals the substantive convergence between the two jurisdictions in the criteria for subject matter eligibility. This article aims to deepen the theoretical understanding of the criteria for assessing the subject matter eligibility of AI-related inventions and to provide practical references for patent drafting and prosecution strategies for innovation entities in the AI field.
On April 1, 2026, the National Intellectual Property Administration released the “2025 China Patent Survey Report”, which was based on the patent survey and data analysis in 2025. The survey paid special attention to the following items: patent transfer and commercialization; patent creation, protection, and overseas intellectual property activities; patent activities in cutting-edge areas of new-quality productivity, including strategic emerging industries, green technologies, and the digital economy. In addition, a special analysis focusing on private enterprises was conducted. The survey covered 27 provinces (including autonomous regions and municipalities), and its subjects were patent holders—enterprises possessing valid patents as of the end of 2024—as well as their valid patents.
Abstract: Currently “common knowledge" has become a hot topic in academic research. How to correctly determine common knowledge has become the key to improve the quality of patent examination. This paper introduces the availability bias theory to point out that the common knowledge determining process tends to produce availability bias, give too much weight to the easily conceived technical knowledge, and turn a blind eye to a lot of other information that must be considered, leading to errors in determining common knowledge. In patent examination, the availability of parts, the availability of work methods and the availability of technical problems may lead to the availability bias. In the end, the countermeasures is put forward.
