A thorough trademark search is the single most important step before filing in China. The China National Intellectual Property Administration (CNIPA) runs the world's largest trademark register, and every registered, pending, refused, and canceled trademark on it is searchable online.
Given China's first-to-file system, finding a conflicting trademark before filing saves both the government fee and the months you would otherwise spend waiting on an application that cannot succeed.

Accessing the CNIPA Trademark Database
The trademark search system is run by the China Trademark Office arm of CNIPA at sbj.cnipa.gov.cn. The English-language CNIPA portal describes the office and its rules, but it is not the search tool. The search system offers several options:
Search Types Available
| Search Type | What It Finds | Best For |
|---|---|---|
| Exact match | Identical trademarks | Confirming specific conflicts |
| Fuzzy/similar | Similar trademarks | Broad clearance searches |
| Phonetic | Trademarks that sound similar | Chinese transliterations |
| Image search | Visually similar designs | Logo and device marks |
| Applicant search | All trademarks by one owner | Competitive intelligence |
Language Considerations
The CNIPA database is primarily in Chinese (Simplified). Search results and trademark details are displayed in Chinese. This creates challenges for foreign owners:
- Trademark names are recorded in Chinese characters
- Goods/services descriptions use CNIPA's Chinese terminology
- Examiner notes and status updates are in Chinese
- Sub-class codes follow CNIPA's own numbering
If a term in this guide is new to you, our trademark glossary explains it in plain English.
Chinese-Character Searches: The Critical Step
For foreign brands, searching only for your English trademark is insufficient. You must also search for Chinese-character equivalents, which may include:
1. Transliteration (音译, Yīnyì)
Phonetic approximation of your brand name in Chinese characters. For example:
- Google → 谷歌 (Gǔgē)
- Nike → 耐克 (Nàikè)
- Walmart → 沃尔玛 (Wò'ěrmǎ)
Search for common transliterations of your trademark, as Chinese consumers or squatters may have already created and registered a phonetic version.
2. Translation (意译, Yìyì)
Meaning-based translation of your brand name. For example:
- Apple → 苹果 (Píngguǒ, literal translation)
- Volkswagen → 大众 (Dàzhòng, "people's" or "public")
- General Motors → 通用 (Tōngyòng, "general use")
3. Phonetic + Meaning Hybrid
Combining sound and meaning for a culturally resonant name. For example:
- Coca-Cola → 可口可乐 (Kěkǒu kělè, "delicious happiness")
- BMW → 宝马 (Bǎomǎ, "precious horse")
- Subway → 赛百味 (Sài bǎi wèi, "surpassing a hundred flavors")
Search for all three types of Chinese equivalents for full clearance.
Understanding China's Sub-Class System
China's classification system divides the 45 Nice classes into sub-classes (also called "similar groups"). This is unique to China and critical for search strategy.
Why Sub-Classes Matter for Searches
- CNIPA examiners assess similarity primarily within sub-classes, not across entire Nice classes
- Two trademarks can coexist in the same Nice class if they are in different sub-classes
- Your search must identify which specific sub-classes cover your goods/services
Example: Class 9 Sub-Classes
| Sub-Class | Description |
|---|---|
| 0901 | Computers and peripherals |
| 0907 | Communication equipment |
| 0908 | Audio/video equipment |
| 0909 | Cameras and optical devices |
| 0913 | Electrical components |
| 0920 | Alarm devices |
| 0921 | Eyeglasses |
| 0922 | Batteries |
A software company would focus on sub-class 0901, not the entire Class 9. But full protection may require filing across multiple sub-classes. Not sure which Nice class your product sits in to begin with? Class Assist walks you from a plain description of what you sell to the right class numbers, and we map those to CNIPA sub-classes when we file.
CNIPA Similarity Assessment Standards
CNIPA applies specific criteria when assessing trademark similarity:
Visual Similarity
- Overall appearance comparison
- Individual character/letter comparison
- Design element comparison
- Color scheme (for color marks)
Phonetic Similarity
- Pronunciation in Mandarin Chinese (Putonghua)
- Tone patterns (Chinese has four tones plus neutral)
- Syllable structure comparison
- Regional pronunciation variations are generally not considered
Conceptual Similarity
- Meaning comparison in Chinese
- Associated imagery or concepts
- Well-known mark associations
- Cultural connotations
The "Comprehensive Judgment" Standard
CNIPA uses a comprehensive judgment approach, weighing all three factors together rather than any single factor in isolation. A trademark that is phonetically similar but visually and conceptually distinct may still be approved.
Interpreting Search Results
When reviewing CNIPA search results, pay attention to:
Trademark Status Indicators
| Status | Meaning |
|---|---|
| 已注册 (Registered) | Active registration, potential blocker |
| 申请中 (Pending) | Application under examination, potential blocker |
| 驳回 (Refused) | Application refused, usually not a blocker |
| 无效 (Invalid) | Registration invalidated. For one year after that date it can still block an identical or similar application (rule in force until 31 December 2026) |
| 撤销 (Canceled) | Registration canceled. For one year after that date it can still block an identical or similar application (rule in force until 31 December 2026) |
| 期满 (Expired) | Registration expired, check grace period |
Red Flags in Search Results
- Identical or near-identical trademarks in your target sub-classes
- Well-known mark registrations that may block even in different classes
- Pending applications with earlier filing dates
- Series filings by the same owner covering many sub-classes (possible squatter)
Limitations of Self-Service Searches
While the CNIPA database is publicly accessible, self-service searches have significant limitations:
- Language barrier: the interface and results are in Chinese
- Sub-class complexity: incorrect sub-class identification leads to incomplete searches
- Chinese-character coverage: most foreign owners miss transliteration and translation searches
- Interpretation expertise: deciding whether a found trademark conflicts requires legal judgment
- Database lag: recently filed applications may not appear for several weeks
- Unregistered use gives you little to stand on: China is first-to-file, so a trademark you have used but not registered gives you only a narrow prior-use defense. The register is what counts, which is why the search matters.
Professional Search Recommendations
For reliable clearance, a professional search should include:
- Full-spectrum language coverage: English, Chinese transliterations, translations, and hybrids
- All relevant sub-classes: the primary sub-class and the related ones
- Status analysis: distinguishing between active blockers and cleared paths
- Risk assessment: opinion on registrability with identified conflicts
- Strategic recommendations: filing strategy based on search findings

Frequently Asked Questions
Is the CNIPA trademark database free to use?
Yes. The CNIPA trademark search database is publicly accessible at no charge. However, the interface is in Chinese, and interpreting results requires knowledge of China's sub-class system and similarity standards.
How far back does the CNIPA database go?
The database covers the register's full history and includes all registered, pending, refused, and canceled trademarks. It is the largest trademark database in the world.
Should I search for Chinese-character versions of my trademark?
Yes. This is one of the most critical steps. You should search for transliterations (phonetic equivalents), translations (meaning-based equivalents), and hybrid versions that combine sound and meaning. Failing to search Chinese equivalents is the most common mistake foreign brands make.
How often is the CNIPA database updated?
The database is updated regularly, but there can be a lag of several weeks between filing and appearance in the search system. For this reason, professional searches often supplement database results with other intelligence sources.
Can I search by image or logo in the CNIPA database?
Yes. CNIPA offers an image search function that allows you to upload a logo or design mark and search for visually similar trademarks. This is particularly useful for device marks and combination marks containing design elements.
What if I find a conflicting trademark in my search?
A conflicting trademark does not necessarily mean you cannot file. Depending on the situation, you may be able to: (1) file in different sub-classes, (2) modify your trademark to create sufficient distinction, (3) challenge the conflicting trademark through non-use cancellation or invalidation proceedings, or (4) negotiate a coexistence agreement.
This guide reflects the CNIPA database system as of 2026. Search procedures and interface features are subject to change; consult a qualified trademark professional for the most current guidance.
