Understanding China’s Trademark Classification System
China’s trademark registration system follows the international Nice Classification system, which categorizes goods and services into 45 distinct classes (34 for goods, 11 for services). However, China implements a unique sub-class system that further divides each class into smaller groups of similar goods or services.
Key Facts About China’s System:
- China uses a sub-class system not found in many other jurisdictions
- Each class contains multiple similarity groups (sub-classes)
- Protection within a sub-class is generally comprehensive for all items in that group
- Registration in one sub-class does NOT automatically protect goods in other sub-classes, even within the same class
This unique structure makes strategic sub-class selection critical for comprehensive trademark protection in China. Unlike the US or EU systems where protection extends to all goods/services within a class, China’s system requires careful selection of specific sub-classes to ensure adequate coverage.
Sub-Class Structure and Similarity Groups
China’s trademark sub-classes are organized into similarity groups – collections of goods or services deemed similar by the China National Intellectual Property Administration (CNIPA).
How Similarity Groups Work
When you register a trademark in one item within a similarity group, you automatically receive protection for all goods/services in that group. This makes selecting representative items strategically important.
Sub-Class Structure Example
Class 25 (Clothing):
– Sub-class 2501: Clothing
– Sub-class 2502: Special sportswear
– Sub-class 2503: Children’s clothing
– Sub-class 2507: Shoes
Critical Consideration
Goods in different sub-classes within the same overall class are NOT considered similar. You must register in each relevant sub-class to receive protection.
Core Sub-Class Selection Strategies
1. Comprehensive Similarity Group Coverage
For each relevant sub-class, select items that provide the broadest protection. Choose:
- Core representative items: Select fundamental goods/services that define the group
- Broadly worded items: When available, choose items with expansive descriptions
- Future-proof selections: Consider potential business expansions
“Selecting the most representative item in each similarity group is crucial. For Class 25 clothing, ‘clothing’ (item 250045) offers broader protection than specific items like ‘T-shirts’ or ‘pants’.”
2. Cost-Effective Registration Approach
China allows registration for up to 10 items per application without additional fees. Strategic selection within this limit can maximize protection while minimizing costs:
| Strategy | Benefit | Example |
|---|---|---|
| Prioritize core business items | Ensures essential protection | Software company prioritizing “computer software” |
| Include complementary goods/services | Extends protection to related areas | Restaurant registering both food services and packaged foods |
| Select broadly worded items | Maximizes coverage within similarity groups | Choosing “clothing” instead of specific garments |
Special Considerations for Segmented Groups
Some similarity groups are segmented into distinct parts. These require special attention as items in different segments are NOT considered similar.
Critical Segmentation Alert
Segmented groups are identified by (一), (二), (三) etc. in the Classification Guide. You must select at least one item from EACH segment to receive comprehensive protection within that group.
Example: Class 29 – Processed Fruits and Vegetables
- Segment (一): Canned fruits, jams, preserved fruits
- Segment (二): Dried fruits, nuts, seeds
If you only register in “canned fruits” (segment 一), you receive NO protection for “dried fruits” (segment 二). Competitors could register similar marks for dried fruits in the same class.
Segmented Group Strategy
For segmented groups:
1. Identify all segments relevant to your business
2. Select at least one item from each relevant segment
3. Choose broadly worded items where possible
4. Verify coverage with the latest China Classification Guide
Defensive Registration and Related Classes
Beyond core business classes, strategic registration in related classes provides important defensive protection against trademark squatters and brand dilution.
Defensive Registration Strategies
Core Business Classes
Register in classes directly covering your current products/services. This is your essential protection foundation.
Related Product Classes
Register in classes covering complementary products. Example: A smartphone manufacturer registering in Class 9 (electronics) and Class 14 (watches) for smartwatches.
Service Classes
Even product-based businesses should consider service classes. Example: A furniture manufacturer registering in Class 37 (furniture repair) and Class 35 (retail services).
Successful Defense Strategy: Xiaomi Corporation
Chinese electronics giant Xiaomi has registered its trademark in all 45 classes as a defensive measure. This comprehensive approach:
- Prevents trademark squatting in unrelated classes
- Protects against brand dilution
- Provides flexibility for future business expansion
- Creates a strong legal position against infringers
While full-class registration may not be practical for all businesses, it demonstrates the value of strategic defensive registration.
Leveraging Cross-Reference Rules
China’s trademark system includes specific cross-reference rules that designate certain goods/services across different classes as similar. Understanding these relationships is essential for comprehensive protection.
Key Cross-Reference Relationships
| Goods/Services | Related Classes | Strategic Importance |
|---|---|---|
| Pharmaceuticals | Class 5 (pharmaceuticals) and Class 44 (medical services) | Essential for healthcare providers and pharma companies |
| Alcoholic beverages | Class 32 (beers) and Class 33 (wines and spirits) | Beverage companies must register in both classes |
| Retail services | Class 35 (retail) and relevant product classes | Retailers need both service and product protection |
| Software and hardware | Class 9 (software) and Class 42 (IT services) | Tech companies require comprehensive coverage |
Cross-Reference Strategy
1. Identify all cross-referenced classes relevant to your business
2. Register in both the core class and cross-referenced classes
3. Select appropriate sub-classes in each related class
4. Consult the latest CNIPA cross-reference guidelines
Balancing Cost and Protection
While comprehensive protection is ideal, budget constraints require strategic decisions. Here’s how to maximize protection while controlling costs:
Priority-Based Selection
Rank sub-classes by business importance. Focus budget on:
– Core products/services
– High-revenue areas
– Critical defensive positions
Phased Registration
Implement protection in stages:
Phase 1: Core business classes
Phase 2: Critical defensive classes
Phase 3: Expansion classes
Efficient Sub-Class Coverage
Maximize coverage within similarity groups by selecting broadly worded items. This reduces the number of items needed while maintaining protection.
Avoid False Economies
While cost management is important, under-protection can lead to:
– Costly opposition proceedings
– Rebranding expenses
– Lost market opportunities
– Legal disputes over infringement
The long-term costs of inadequate protection often far exceed registration expenses.
Common Mistakes to Avoid
1. Underestimating Sub-Class Complexity
Assuming that registering in a class provides comprehensive protection. In China, sub-class selection is critical.
2. Ignoring Segmented Groups
Failing to register in all segments of a segmented group, leaving significant protection gaps.
3. Overlooking Cross-Reference Relationships
Neglecting to register in classes that are cross-referenced with your core business classes.
4. Literal Translation Errors
Translating product descriptions directly without considering China’s specific classification terminology.
5. Neglecting Defensive Registration
Focusing only on current products/services without considering future expansion or defensive positions.
“The most costly trademark mistakes in China stem from incomplete sub-class selection. I’ve seen companies save $500 on registration only to spend $50,000 fighting infringement in an unprotected sub-class.”
Ongoing Maintenance and Updates
Trademark protection requires continuous attention. China’s classification system evolves, and your business needs change.
Key Maintenance Activities
- Annual Classification Review: CNIPA updates classifications annually – monitor for changes affecting your marks
- Business Expansion Monitoring: Register in new sub-classes when expanding product lines
- Competitor Watch: Monitor competitor registrations in related sub-classes
- Renewal StrategyChina trademarks are valid for 10 years – plan renewals well in advance
Monitoring Tools and Services
Consider implementing:
– Automated trademark watching services
– Regular IP audits (at least biennially)
– Engagement with local trademark attorneys
– Subscription to CNIPA classification updates
