## Practical Application Guide for International Trademark Classification Class Headings in China
The International Classification (Nice Classification) serves as the core basis for determining the classes of goods and services in trademark registration. In China, the China National Intellectual Property Administration (CNIPA) strictly adheres to the 12th edition of the International Classification of Goods and Services for the Purposes of the Registration of Marks (i.e., the Nice Classification). However, in practice, a significant number of applicants and agencies misunderstand the application of class headings—often mistakenly using them as specific goods/services items—leading to refusals, oppositions, or even loss of rights. This article systematically outlines the practical application rules, common errors, and response strategies for International Classification class headings in China, helping applicants build a correct framework for understanding classification.
## I. Legal Nature and Functional Positioning of International Classification Class Headings
Pursuant to the Protocol Relating to the Madrid Agreement Concerning the International Registration of Marks and the CNIPA-published "Similar Goods and Services Classification Table," the International Classification is divided into 45 classes, with Classes 1–34 covering goods and Classes 35–45 covering services. Each class has a "Class Heading," which is a general description of the scope covered by that class.
The legal nature of class headings, in CNIPA practice, should be understood as "guiding explanations" rather than "specific designations." The functions of class headings are as follows:
1. **Defining Class Boundaries**: Helping applicants determine which class their goods or services should fall into. For example, the class heading for Class 9 explicitly refers to "scientific, nautical, surveying, photographic, cinematographic, optical, weighing, measuring, signaling, checking (supervision), life-saving and teaching apparatus and instruments; apparatus and instruments for conducting, switching, transforming, accumulating, regulating or controlling electricity," etc., allowing applicants to preliminarily assess the general归属 of electronic products.
2. **Reference Benchmark for Examination**: When determining whether goods/services are similar, CNIPA examiners use the class headings as a reference, combined with a comprehensive assessment based on specific items in the Classification Table. Class headings are not the sole basis for similarity judgments but provide a macro framework.
3. **Reference for Interpreting the Scope of Rights**: In trademark infringement disputes, class headings may serve as one of the reference factors for interpreting the scope of approved goods/services, but they cannot independently serve as the basis for determining the scope of protection.
It is crucial to emphasize: **In China, class headings themselves cannot be filed as specific goods or service items.** Applicants must select specific goods/service item names from the Similar Goods and Services Classification Table, rather than merely filling in the class heading. This is a significant difference between Chinese examination practice and that of some other countries.
## II. Practical Distinction Between Class Headings and Specific Items
| Comparison Dimension | Class Heading | Specific Goods/Service Item |
|:---|:---|:---|
| **Legal Effect** | Class guidance, not a specific designation | Core basis for determining the scope of protection |
| **Filing Method** | Cannot be directly filed as an item | Must select a specific item for filing |
| **Examination Standard** | Reference standard | Substantive examination basis |
| **Limitation on Amendment** | Expansion not permitted after designation | Can be deleted but cannot be added beyond the scope |
| **Scope of Protection** | No independent protective effect | Defines the boundary of trademark exclusivity |
| **Similarity Judgment** | Macro guidance | Micro comparison benchmark |
| **Official Fees** | No separate fee | Additional fees for items exceeding 10 |
| **International Differences** | Some countries accept full class protection via headings | China requires specific itemization |
The table above clearly illustrates the essential differences between class headings and specific items. In practice, one of the most common grounds for refusal is "non-standard goods/services items"—meaning the applicant submitted a broad description resembling a class heading rather than a standard item name listed in the Classification Table.
## III. CNIPA Examination Rules Regarding the Use of Class Headings
CNIPA follows these core rules for the application of class headings:
### Rule 1: Class Headings Cannot Replace Specific Items
According to Article 13 of the Implementing Regulations of the Trademark Law, a trademark registration application shall "be filled in according to the published classification of goods and services." Each specific item in the Similar Goods and Services Classification Table has a unique six-digit code. If an application only fills in the class heading without listing specific coded items, CNIPA will issue a notice of correction, requiring the applicant to make the correction within a specified time limit.
**Typical Case**: An applicant designated Class 35 "Advertising"—"Advertising" is part of the Class 35 class heading. However, according to the Classification Table, specific items such as "Advertising (350039)", "Publicity (350039)", or "Outdoor advertising (350003)" should be selected. Simply writing "Advertising" would be considered non-standard and require correction.
### Rule 2: Wording from Class Headings May Be Accepted as Item Names
If a certain expression within a class heading is identical to a standard item name in the Classification Table, that expression can be used as a specific item. For example, the Class 9 class heading includes the term "computers," and the Classification Table for Class 9 happens to contain the standard item "Computers (090372)." Since they coincide, this can be filed.
### Rule 3: Broad Expressions Face Refusal Risk
Class headings are often general descriptions, such as Class 1's "chemicals used in industry, science, photography, agriculture, horticulture and forestry." Such expressions are too broad and do not meet the Classification Table's requirement for item specificity. In CNIPA examination, vague descriptions like "chemicals" will be directly refused. Applicants must select specific chemical names, such as "Industrial chemicals (010458)."
### Rule 4: Changes to Class Headings Do Not Affect Registered Trademarks
When the Nice Classification is updated, causing changes to class headings, the scope of approved goods/services for already registered trademarks remains unaffected. For example, the 2022 edition of the Nice Classification adjusted Class 9's "recorded programs" to "recorded or downloadable software, platforms, and programs," but this has no impact on trademarks previously registered for "recorded programs" in Class 9.
## IV. Application of Class Headings in Trademark Oppositions and Invalidations
In trademark opposition and invalidation proceedings, the role of class headings is mainly reflected in the following aspects:
**Judgment of Similar Goods/Services**. When determining whether the opposed trademark and the cited trademark constitute similar goods/services, CNIPA and the courts will refer to the class attributes revealed by the class headings. For example, the Class 5 class heading covers "pharmaceutical preparations." Even if the cited trademark is registered for "pharmaceuticals for human use" and the disputed trademark designates "nutritional supplements for medical use," under the pharmaceutical attribute revealed by the class heading, they may be deemed similar goods. However, this requires a comprehensive judgment considering factors such as function, purpose, production department, sales channels, and consumers, with the class heading serving only as one reference factor.
**Interpretation of the Scope of Goods/Services**. When the description of approved items on a trademark registration certificate is ambiguous, the class heading of that class can be used for interpretation. For instance, if a trademark is approved for use on Class 42 "Computer programming," and the Class 42 class heading explicitly points to "scientific and technological services and research and design services relating thereto; industrial analysis and industrial research services; design and development of computer hardware and software," it can be clarified that "computer programming" is a technical service, not within the scope of goods sales in Class 9.
**Handling Differences in Class Headings for Cross-Border Applications**. For international registrations designating China through the Madrid System, if the country of origin allows full class coverage using class headings (as practiced in the US, EU, etc.), CNIPA will require the conversion of class headings into specific items from the Classification Table upon entering the national phase in China. Applicants should consider China's classification requirements at the international application stage and reserve sufficient room for selecting specific items.
## V. Practical Recommendations for Classification Strategy
Based on the above analysis, the following classification strategy recommendations are offered for applicants seeking adequate and stable trademark protection in China:
1. **Prioritize Standard Items from the Classification Table**. Select standard item names from the Similar Goods and Services Classification Table that best match your business, avoiding self-created items or broad expressions resembling class headings. CNIPA periodically updates the Classification Table; it is recommended to obtain the latest version via the CNIPA official website or professional trademark agencies.
2. **Strategically Cover Related Items**. The same goods may correspond to multiple classes due to different functions or purposes. For example, a mobile application may involve Class 9 (downloadable software), Class 42 (Software as a Service SaaS), and potentially Class 35 (online advertising, business management). It is advisable to conduct cross-class searches and develop a registration plan of "core classes + defensive classes."
3. **Fully Utilize the "Multi-Class Application" System**. Since 2014, China has implemented a "multi-class application" system, allowing one application to designate multiple classes. This effectively reduces official fees for multi-class registrations and simplifies subsequent management and renewal processes. However, note that the risk of refusal for goods/services in different classes within the same application is independent; refusal in one class does not affect the examination process for other classes.
4. **Monitor Classification Updates**. The Nice Classification undergoes minor adjustments annually and major revisions every five years. CNIPA typically updates the Classification Table on January 1st each year to align with classification changes. Trademark applicants should monitor classification updates, promptly adjust filing items for new applications, and make necessary supplementary registrations for existing trademarks to ensure the scope of protection keeps pace with the times.
5. **Engage Professional Agencies for Classification Assessment**. Complex goods/services classifications (e.g., those involving emerging fields like artificial intelligence, blockchain, biotechnology) often require professional judgment. WeRights offers trademark classification pre-assessment services to assist applicants in formulating optimal classification strategies, avoiding overly narrow scopes of rights or refusal risks due to improper classification.
## VI. Common Misconceptions and Risk Warnings
The following are the most common misconceptions regarding class headings in Chinese trademark registration:
- **Misconception 1**: "Full class protection via class headings" — This does not work in China. Believing that selecting a class heading for a class grants protection for all goods in that class is the most serious misunderstanding. China does not recognize the effect of "full coverage by class headings"; the scope of protection is limited strictly to the actual goods/services items selected.
- **Misconception 2**: The more items, the better. Blindly selecting a large number of items unrelated to the core business not only increases official fees but may also create difficulties in trademark use disputes. If challenged for non-use for three consecutive years, failing to provide evidence of use for the selected items may lead to their cancellation.
- **Misconception 3**: Ignoring qualifiers in the Classification Table. For example, in Class 9, "Computer software (recorded)" and "Downloadable computer software" are two different items. The former refers to software on a physical medium, while the latter refers to software downloaded via a network. Incorrect selection may result in a scope of protection deviating from the actual business.
- **Misconception 4**: Overly simplistic selection of service trademark classes. Many internet companies only register technical services in Class 42, neglecting key classes such as Class 35 "Advertising, business management" and Class 45 "Online social networking services," leading to an inability to cover actual business operations during enforcement.
- **Misconception 5**: Believing the International Classification is "omnipotent." The International Classification applies to trademark registration, but the determination of "similar goods/services" in trademark infringement judgments is not entirely equivalent to the classification in the Classification Table. In judicial practice, courts have the authority to deviate from the Classification Table, recognizing goods in different classes as similar or goods in the same class as dissimilar.
## Conclusion
International Classification class headings are a fundamental concept in China's trademark registration system, yet their misuse rate in practice is extremely high. Applicants should correctly understand the guiding function of class headings rather than their protective function, adhering to the filing principle of "class headings as guidance, specific items as the foundation." In global trademark portfolio planning, fully considering the particularities of Chinese classification examination and preparing filing materials according to Chinese standards at the international stage are key to improving registration success rates and reducing refusal risks. Through professional classification strategy planning and precise item selection, applicants can establish a trademark rights system with clear boundaries and strong protection in the Chinese market.
