How to Search Registered Trademarks in China Easily
Key Facts
| Fact | Detail |
|---|---|
| Registration principle | China follows “first-to-file,” so search rights depend on filing date, not first use[1] |
| Official search portal | China Trademark Office Online Search, sbj.cnipa.gov.cn/sbj/sbcx/[2] |
| Active registered trademarks in China | 53.032 million as of end of 2025, up 6.5% year over year[3] |
If you plan to sell products or license a brand in China, searching the trademark register is the single most important step before you file. China’s trademark system rewards the first applicant, not the first user, so a five-minute search can save months of delay and thousands of dollars in wasted application fees. This guide walks through why trademark search matters, which official CNIPA tools to use, how to run a search step by step, and what the results can and cannot tell you.
1. Why Trademark Search Matters in China
China applies a strict “first-to-file” principle. Ownership of a trademark right depends on who files the application first, not who used the mark first in commerce[1]. That single rule makes trademark search a critical risk-control step before any brand enters the Chinese market.
Avoiding Direct Conflicts
Under Article 28 of the Trademark Law, CNIPA will reject an application if the mark is identical or similar to a trademark already registered, or given preliminary approval, on the same or similar goods[4]. A search before filing lets you catch this conflict early, rather than losing months of examination time and the official filing fee. Our related guide on common trademark rejection reasons in China walks through the most frequent grounds examiners cite.
Identifying Hidden Risks
A complete search needs to cover more than just live registrations. It should also check:
- Trademarks with preliminary approval awaiting publication
- Pending applications still under examination
- Marks currently in opposition, cancellation, or invalidation proceedings
- Well-known trademarks, which receive cross-class protection regardless of the goods or services listed
Well-known mark status is the trickiest risk to spot, because these marks are protected outside their registered classes. A name that looks available in your specific class can still be blocked if a well-known mark exists in an unrelated category. This is one reason trademark squatting remains a persistent problem for foreign brands entering China; see our breakdown of trademark squatting in China for real examples.
Saving Time and Cost
Search is not a mandatory legal prerequisite for filing, but skipping it is a false economy. Rejected applications still cost the official fee, delay your filing date, and can force a rebrand mid-launch. For context on what a rejection actually costs, see our complete cost guide to China trademark registration fees.
The Scale of China’s Trademark Register
The size of the register is exactly why search matters so much. In 2025 alone, CNIPA registered 4.206 million new trademarks and closed 384,000 trademark review cases and 112,000 opposition cases, with average examination time around four months and a pass rate above 97%[3][5]. By the end of 2025, China’s active registered trademark total reached 53.032 million, of which 49.877 million were domestic registrations excluding Hong Kong, Macao, and Taiwan[3]. Chinese applicants also filed 6,718 Madrid Protocol international applications that year[3]. Searching against a register this large is not optional diligence — it is basic risk management.
2. Official Trademark Search Systems in China
CNIPA, China’s National Intellectual Property Administration, operates the official channels for trademark search. Using unofficial or third-party databases can produce outdated or incomplete results, so start with these government sources.
China Trademark Office Website
The China Trademark Office maintains the primary portal at sbj.cnipa.gov.cn[2]. This is the authoritative source for trademark status, classification, and examination records.
Trademark Online Search System
The dedicated search tool sits at sbj.cnipa.gov.cn/sbj/sbcx/[2] and offers three main search modes:
- Similarity search — the most commonly used mode for word marks
- Comprehensive search — search by trademark name, applicant, or registration number
- Image search — launched May 22, 2026, for logo and design marks[6]
You can also reach the search tools through the CNIPA Public Service Platform at ggfw.cnipa.gov.cn[2], which links out to most CNIPA online services in one place.
Unified Identity Authentication System
Since 2026, the Trademark Online Search System and other CNIPA tools require login through the Public Service Platform’s unified identity authentication system, registered at sso.cnipa.gov.cn[2]. You need a verified account before you can run a search, so registering early saves time when you are working against a launch deadline. For a broader walkthrough of these tools, our earlier post on the complete guide to China trademark search and the guide to mastering CNIPA trademark search cover additional search scenarios.
3. Step-by-Step: How to Search a Trademark in China
Once your account is ready, the search process itself takes only a few steps. Here is the practical workflow.
Step 1: Register an Account
Go to the CNIPA Public Service Platform’s unified identity authentication system and complete registration[2]. Enter accurate personal or company information, since mismatched details can delay verification.
Step 2: Log In to the Search System
Sign in to the China Trademark Office website and open the “Trademark Online Search” section from the main menu.
Step 3: Choose the Right Search Method
Your search method depends on the type of mark:
- Word marks: select “Similarity Search,” enter the correct Nice Classification, then type in your keyword or brand name
- Image marks: select “Image Search” and upload the logo file directly
Step 4: Filter and Analyze the Results
Cross-check your results against the Classification Table for Similar Goods and Services to confirm you are searching the correct class and subclass. CNIPA examiners judge similarity based on the likelihood of confusion among the relevant public, applying three core principles: isolated observation, overall comparison, and dominant-part comparison[7]. Reading results the same way examiners do will give you a far more realistic risk assessment than a simple keyword match. If your search turns up conflicts you don’t understand, our guide on proving trademark distinctiveness in China explains how examiners weigh similarity against distinctiveness.
4. New in 2026: Image-to-Image Search for Logo Trademarks
What Changed
CNIPA launched an image-to-image search function on May 22, 2026[6]. Before this update, searching for logo and design trademarks meant relying on manual Vienna Classification design codes, a slow and error-prone process for anyone unfamiliar with the coding system.
How the Feature Works
The path is: China Trademark Office → Trademark Online Search System → Similarity Search → select “Search Method – Image Search”[6]. Upload your logo file, and the system compares it against registered and pending image marks to flag visually similar results.
Why It Matters
This upgrade meaningfully speeds up the pre-filing process for logo-heavy brands, since design-code lookup was historically one of the biggest bottlenecks in DIY trademark search. It is especially useful for consumer brands, packaging designers, and e-commerce sellers whose trademarks are primarily visual rather than text-based.
An Important Limitation
CNIPA is explicit that image search results are for reference only and carry no legal binding effect[6]. A visual match, or the absence of one, does not predict how an examiner will rule. Treat the tool as a screening aid, not a final answer — particularly for marks that will anchor a significant product launch or licensing deal, where our team can run a deeper comparison; see our trademark and copyright services for what a professional review covers.
5. Legal Basis for Trademark Search
Trademark search in China is not an isolated administrative habit — it is grounded directly in the Trademark Law. The law was revised on June 26, 2026 by the Standing Committee of the 14th National People’s Congress and takes effect January 1, 2027[8]. The table below maps the provisions most relevant to search practice.
| Article | Content Summary | Relevance to Search |
|---|---|---|
| Article 13 | CNIPA must strengthen digital and intelligent trademark public service infrastructure and publish trademark information completely, accurately, and promptly[8] | This is the legal basis for the official search systems themselves |
| Article 10 | An applicant may handle a trademark registration application directly or through an entrusted agency[9] | Confirms both self-search and agency-assisted search are legitimate paths |
| Article 28 | An application will be rejected if it is identical or similar to a trademark already registered or given preliminary approval on the same or similar goods[4] | The core substantive rule that search is designed to help you avoid triggering |
| Article 56 | The exclusive right to use a registered trademark is limited to the approved mark and the approved goods or services[9] | Explains why class-by-class and subclass search accuracy matters |
Two supporting documents round out the legal and practical framework: the Trademark Examination and Adjudication Guidelines, which set out how examiners apply the similarity test, and the Classification Table for Similar Goods and Services, which determines whether two marks are considered to compete in the same commercial space[7]. Reading a search result without reference to these two documents is like reading a legal ruling without the statute it applies. For a deeper look at how examiners weigh these standards, see our post on the China trademark registration process.
6. Limitations of Trademark Search Results
Search Is Not a Legal Prerequisite
It’s worth repeating: trademark search is not a mandatory step before filing in China. A business can submit an application directly without ever running a search. The Trademark Law does not condition filing eligibility on prior search.
Search Is Not a Guarantee
More importantly, a clean search result carries no legal binding force and cannot guarantee that CNIPA will approve your application. Even when a search turns up no conflicting prior rights, an examiner can still reject the mark for reasons a search cannot fully predict, including:
- Lack of distinctiveness — marks seen as descriptive, generic, or purely decorative
- Prohibited content — names, symbols, or terms restricted under Articles 15 and similar provisions
- Hidden well-known mark conflicts — cross-class protection that isn’t always visible through a standard class-based search
This is why experienced counsel treat search as a risk-reduction tool rather than a pass/fail predictor. If your search comes back clean but you’re still unsure about distinctiveness or wording, it’s worth a second look before you file — see our guide on what to check before filing a China trademark.
What Search Actually Achieves
Framed correctly, search reduces — but does not eliminate — filing risk. It catches the most common and most costly conflict: an identical or highly similar mark already sitting on the register in your class. That single function alone justifies the time it takes, even though it cannot cover every possible ground for refusal.
7. Common Search Mistakes to Avoid
Even diligent applicants make avoidable errors when searching CNIPA’s databases. The table below lists the most frequent mistakes alongside the correct approach.
| Mistake | Correct Practice |
|---|---|
| Only searching the English name, ignoring Chinese | Chinese examiners assess similarity by sound, form, and meaning — search Chinese-character and pinyin equivalents too |
| Ignoring subclasses | Conflicts in related subclasses can still block registration — always check the full subclass range |
| Searching only registered marks | Also check marks with preliminary approval, pending applications, and marks in opposition, cancellation, or invalidation proceedings |
| Overlooking well-known trademarks | Well-known marks receive cross-class protection and require a dedicated screening step |
| Assuming a clean search guarantees registration | Treat results as reference information, not a final approval prediction |
Why the Chinese-Language Gap Trips Up Foreign Applicants
The most common mistake we see from foreign clients is searching only the Latin-alphabet version of a brand name. Chinese trademark examination compares marks phonetically and semantically as well as visually, so a name that looks nothing alike in English can still be judged confusingly similar once translated or transliterated. Brands entering China typically need a Chinese name strategy alongside the English mark — our guide on how to come up with a Chinese brand name covers this in more depth, and our piece on checking whether your brand name is available in China walks through the practical checks.
8. When to Use a Professional Trademark Agency
When Agency Representation Is Mandatory
For most foreign applicants, this isn’t optional. Under the Trademark Law, a foreign natural person or foreign enterprise without habitual residence or a place of business in China must file through a legally established trademark agency[9]. Self-search is always permitted, but self-filing generally is not for entities in this category.
Complex Image Mark Interpretation
Image search results need professional reading. A visual similarity flagged by the system may or may not translate into a real legal conflict once you account for color, composition, and the dominant-part comparison standard examiners actually apply.
Well-Known Mark Screening
Cross-class well-known mark risk is difficult to identify through standard class-based search. A professional screening draws on case precedent and CNIPA’s recognition history to flag risks a keyword search will miss.
Registration Strategy Planning
Multi-class filing strategy, Madrid Protocol international registration, and portfolio sequencing all benefit from experienced planning. For a broader look at whether the Madrid route makes sense for your brand, see is the Madrid Protocol worth it for China trademarks. YCIP’s trademark and copyright services cover search, filing, and portfolio strategy from a single team, and our consultation and litigation support service is available if a conflict escalates beyond the filing stage.
Conclusion
With more than 53 million active registered trademarks on China’s register, search is no longer a nice-to-have — it is a baseline step for any brand entering the Chinese market. The May 2026 image-to-image search upgrade has made logo clearance faster than ever, but it doesn’t remove the legal limits on what a search result can promise. A clean search reduces risk; it does not guarantee approval.
The safest approach combines self-search for a first pass with professional review before you commit to filing, especially for image marks, well-known mark screening, or multi-jurisdiction strategy. Yucheng IP Law (YCIP) has guided foreign businesses through China’s trademark system for years, combining CNIPA search access with the legal judgment a search tool cannot replace.

Frequently Asked Questions
Do I have to search before registering a trademark in China?
No. Trademark search is not a legal prerequisite for filing — you can submit an application directly. That said, because China follows first-to-file, skipping search significantly raises your risk of rejection, wasted fees, and delayed market entry.
Do I need an account to use the China Trademark Office search tool?
Yes. Searching through the Similarity Search section requires a registered, logged-in account. Since 2026, the Trademark Online Search System connects to the CNIPA Public Service Platform’s unified identity authentication system at sso.cnipa.gov.cn, where you register once and use that login across CNIPA’s online services.
How do I search for an image or logo trademark in China?
Since May 22, 2026, you can use the “Image Search” function inside the Trademark Online Search System: China Trademark Office → Trademark Online Search System → Similarity Search → Search Method – Image Search. Upload your logo file directly; results are for reference only.
Does a clean trademark search guarantee registration will succeed?
No. Search results carry no legal binding force. Even with no conflicting prior rights found, CNIPA can still reject an application for lack of distinctiveness, prohibited content, or an undetected well-known mark conflict. Treat search as a risk-assessment tool, not a guarantee.
Is trademark search in China free?
Yes, the official CNIPA search tools are free for both individuals and companies. Professional search services — such as well-known mark screening, image mark interpretation, or a full registrability opinion — are offered by trademark agencies for a service fee.
How do foreign companies search and register trademarks in China?
Foreign companies can freely self-search through the China Trademark Office website. For filing, however, a foreign natural person or enterprise without a habitual residence or place of business in China must engage a legally established trademark agency to submit the application. China is also a member of the Madrid Protocol, so foreign applicants can alternatively pursue an international registration designating China.
What should a complete trademark search cover?
A thorough search should check: active registered trademarks, marks with preliminary approval pending publication, pending applications under examination, marks in opposition, cancellation, or invalidation proceedings, cancelled or expired marks that may still pose a residual conflict, and well-known trademarks, which require a dedicated cross-class search regardless of goods or services class.
