How to Search Registered Trademarks in China Easily
Key Facts
| Key Fact | Detail |
|---|---|
| China’s trademark system rule | First-to-file, not first-to-use, under Trademark Law Article 28[3] |
| Active registered trademarks in China | 53.032 million as of end-2025, up 6.5% year-on-year[5] |
| Official search cost | Free, via the China Trademark Office’s online query system[1] |
If you’re planning to enter the Chinese market, a trademark search is one of the first things worth doing. China now has over 53 million active registered trademarks[5], and the country runs on a first-to-file principle rather than first-to-use. That combination makes it entirely possible for another party to already hold rights to a name, logo, or slogan you assumed was yours to claim. This guide walks through why the search matters, which official tools to use, how to run a search step by step, and what to do once you have your results.
Why Trademark Search Matters in China
The First-to-File Principle
China operates under a first-to-file rule. Ownership of a trademark generally goes to whoever files the application first, not whoever used the mark first in commerce. This is a fundamentally different approach from first-to-use jurisdictions, and it catches many foreign brands off guard. A company might have used a name for years elsewhere, only to discover a local party has already registered it in China. Under this framework, searching before you file isn’t just good practice — it’s the only way to know where you actually stand before committing resources to a brand name.
What the Law Says About Conflicting Marks
According to Article 28 of the PRC Trademark Law, an application will be rejected if the mark is identical or similar to a trademark already registered, or preliminarily approved, by another party for the same or similar goods[7]. That single clause is the reason search exists as a practice at all — it defines exactly what a search needs to rule out.
“Where a trademark applied for registration is identical with or similar to another person’s trademark already registered or preliminarily approved for use on the same or similar goods, the application shall be rejected.” — PRC Trademark Law, Article 28[7]
Hidden Risks a Search Uncovers
A complete search needs to go beyond a simple name check. It should screen for:
- Currently valid registered marks
- Marks under preliminary approval publication
- Pending applications still under examination
- Marks caught up in opposition, cancellation, or invalidation proceedings
- Well-known marks, which receive cross-class protection regardless of the goods or services listed
That last category matters more than most applicants expect. A well-known mark isn’t limited to its registered class — a name recognized as well-known in one industry can block a similar mark in an entirely unrelated one. Missing this step is one of the most common reasons a seemingly “clear” search still ends in rejection.
2025 Trademark Filing Snapshot
The scale of China’s trademark system explains why due diligence has become non-negotiable. In 2025 alone, China recorded 4.206 million new trademark registrations, closed 384,000 trademark review cases, and resolved 112,000 opposition cases, with an average examination cycle of four months and an approval rate above 97%[5]. For context on how to interpret these figures in your own filing strategy, see our complete guide to China trademark search.
Official Trademark Search Systems in China
The China Trademark Office Portal
The primary, authoritative source for trademark data in China is the China Trademark Office (CTMO), the division of the China National Intellectual Property Administration (CNIPA) responsible for trademark examination and registration. Its official portal, accessible at sbj.cnipa.gov.cn, is the starting point for any legitimate search[1]. This is the only source that reflects the government’s own examination records, so third-party tools should always be cross-checked against it. Our guide to mastering CNIPA trademark search walks through how to navigate the portal in more detail.
The Trademark Online Search System
Within the CTMO portal sits the Trademark Online Search System, the actual query tool applicants use[2]. It offers several distinct search modes:
| Search Mode | Best Used For |
|---|---|
| Trademark Similarity Search | The most common method — checking word marks against existing registrations by class and keyword |
| Comprehensive Search | Searching by trademark name, applicant name, or other bibliographic details |
| Image-Based Search | Uploading a logo file to check figurative mark similarity (launched May 22, 2026) |
For a closer walkthrough of each mode, see our trademark search tool guide and database search guide.
The Unified Login Requirement
As of 2026, the Trademark Online Search System and related tools connect to the National Intellectual Property Public Service Platform’s unified identity authentication system[3][4]. In practice, this means you can no longer search anonymously — you need to register an account through the unified login portal before running a query. Applicants and agencies alike must complete this registration step, entering accurate personal or organizational details, before the search functions become accessible.
Why Using Official Channels Matters
Third-party search tools and databases exist, and some are genuinely useful for preliminary screening. But because registration status, opposition periods, and ownership records change constantly, only the official CNIPA systems reflect real-time examination data. If you’re checking whether your brand name is available in China, always confirm any third-party result against the official portal before making a filing decision.
How to Search a Registered Trademark in China (Step-by-Step)
Step 1: Register an Account
Visit the National Intellectual Property Public Service Platform’s unified identity authentication system and complete registration[4]. You’ll need to provide accurate personal or business information — errors here can delay your access to the search tools, so double-check details like your legal entity name and contact information before submitting.
Step 2: Access the Query System
Once logged in, navigate to the China Trademark Office website and open the “Trademark Online Search” section from the main menu[2]. This is the gateway to all the search modes described above.
Step 3: Choose Your Search Method
Your choice here depends on what kind of mark you’re checking:
- Word marks: Select “Trademark Similarity Search,” enter the relevant Nice Classification (International Classification of Goods and Services) number, and input your keyword or proposed name.
- Figurative marks: Select the image-search option and upload your logo file directly.
Step 4: Filter and Interpret the Results
Before drawing conclusions, check the Classification Table of Similar Goods and Services to confirm you’re searching under the correct class — a surprising number of applications get filed under the wrong subclass entirely. When reviewing results, similarity determinations in China follow three core examination principles: isolated observation, overall comparison, and dominant-feature comparison, all centered on whether the relevant public is likely to be confused[7]. If you’d like a second opinion on borderline results, our team can help you check a trademark before filing to avoid an avoidable rejection.
New in 2026: Image-Based Trademark Search
What Changed
On May 22, 2026, the China Trademark Office officially launched an image-based search function within the Trademark Online Search System[6]. Before this update, checking a figurative or logo-based mark for conflicts required navigating complex graphic element coding — a process that was slow and difficult for anyone without specialized training.
How the Feature Works
The path is straightforward: from the China Trademark Office website, go to “Trademark Online Search System — Trademark Similarity Search,” then select “Search Method — Image-Based Search,” and upload your trademark’s image file[6]. The system accepts standard image formats and returns visually similar registered and pending marks for comparison.
What It Means for Applicants
This update meaningfully lowers the barrier to screening logo-based trademarks, which historically were among the hardest to search independently. That said, one caveat applies consistently across every official search tool: results are for reference only and carry no legal binding force[6]. A clear result from the image search doesn’t guarantee that a human examiner at CNIPA will reach the same conclusion during formal review — visual similarity assessment ultimately involves judgment calls that automated tools can only approximate.
When to Get a Professional Read
Figurative marks are particularly prone to disputes over “dominant feature” comparison — two logos can look quite different overall while still sharing an element that an examiner considers the visually dominant, and therefore legally significant, part of the design. If your search turns up marks that are close but not identical, that’s exactly the scenario where a professional second opinion earns its cost. Our comparison of trademark search engines in China covers additional tools worth cross-referencing alongside the official portal.
Legal Basis for Trademark Search in China
The Governing Statute
The core legal framework is the Trademark Law of the People’s Republic of China, most recently revised on June 26, 2026[7]. Several provisions directly shape why and how search is conducted.
| Article | What It Covers | Relevance to Search |
|---|---|---|
| Article 13 | Requires the State Council’s trademark administration department to strengthen informatized, intelligent trademark public services and release trademark information completely, accurately, and promptly[7] | Legal basis for the official search systems existing at all |
| Article 11 | Foreign individuals or enterprises without a domicile or place of business in China must appoint a licensed trademark agency to handle registration and related matters[7] | Distinguishes who may search independently versus who needs agency support for filing |
| Article 28 | Applications identical or similar to marks already registered or preliminarily approved for the same or similar goods will be rejected[7] | The direct legal basis for what a search is trying to rule out |
| Article 56 | The exclusive right to use a registered trademark is limited to the approved mark as used on the approved goods[7] | Underscores why class-by-class searching matters |
“The State Council’s trademark administration department shall strengthen the development of an informatized and intelligent public service system for trademarks, and shall release trademark information completely, accurately, and promptly.” — PRC Trademark Law, Article 13[7]
Supporting Guidance Documents
Beyond the statute itself, two supporting documents shape how examiners apply these rules in practice: the Trademark Examination and Adjudication Guidelines, and the Classification Table of Similar Goods and Services. Neither carries the force of law on its own, but both directly determine how a similarity assessment plays out during examination, so they’re worth reviewing alongside the primary statute — particularly if you’re weighing whether to register a trademark in China across multiple classes.
Limitations of Trademark Search Results
Search Is Not a Legal Prerequisite
It’s worth being direct about this: trademark search is not a legally mandated step before filing in China. An applicant can submit directly without ever running a search. The reason search is still standard practice is risk management, not legal obligation.
No Search Result Is Binding
Every official search tool carries the same disclaimer for a reason — results have no legal binding force and cannot guarantee that an application will be approved. Even when a search turns up no conflicting prior mark, rejection is still possible for reasons a database search simply cannot detect, including:
- Lack of distinctiveness in the proposed mark
- Conflicts with prohibited content under the Trademark Law
- An undisclosed conflict with a well-known mark that isn’t obvious from a standard database entry
Setting the Right Expectations
The practical takeaway is to treat search as a risk-reduction tool, not a registration guarantee. It substantially narrows your exposure and helps you avoid the most common and most costly rejection scenario — direct conflict with an existing mark — but it cannot eliminate every path to rejection. If your search results look promising but you’re weighing several possible class combinations, it may help to review common trademark rejection reasons and solutions before you file, so you know what a search alone won’t catch.
Common Search Mistakes to Avoid
| Common Mistake | Better Approach |
|---|---|
| Searching only in English, ignoring Chinese-language equivalents | Chinese examiners assess sound, appearance, and meaning together — search Chinese characters and pinyin transliterations too |
| Ignoring subclasses within a Nice class | Conflicts in related subclasses can still block registration, not just exact-class matches |
| Searching only fully registered marks | Also check marks under preliminary publication, pending applications, and marks in opposition, cancellation, or invalidation proceedings |
| Overlooking well-known mark status | Well-known marks receive cross-class protection and require a dedicated screening step |
| Treating a clear preliminary search as a registration guarantee | Remember that results are for reference only — build in a margin for examiner discretion |
Why the Chinese-Language Gap Trips Up Foreign Applicants
This deserves extra emphasis because it’s the mistake we see most often from foreign clients. A name that seems entirely unique in English can closely resemble an existing Chinese mark in sound (读音), appearance (字形), or meaning (含义) — any one of which can trigger a similarity finding. If you haven’t yet settled on a Chinese brand name, our guide on choosing a Chinese brand name is worth reading before you search, not after.
Why Pending and Disputed Marks Matter Just as Much
Applicants frequently search only for marks that show as “registered,” missing marks still working through the pipeline. A mark under preliminary publication or still pending examination can block your application just as effectively as one that’s already fully registered — and by the time it does register, your own application may already be caught in the conflict. For ongoing verification after you file, see how to check trademark status in China.
When to Use a Professional Trademark Agency
When Professional Help Is Legally Required
For some applicants, this isn’t optional. Under Article 11 of the Trademark Law, foreign individuals, foreign enterprises, or other foreign organizations without a domicile or place of business in China must appoint a licensed trademark agency to handle registration and related matters[7]. Self-filing simply isn’t available to this category of applicant — the search can be done independently, but the filing itself requires an agent.
When It’s Legally Optional but Practically Valuable
Beyond that legal requirement, professional support becomes valuable in several recurring scenarios:
- Complex figurative marks — where image-search results need expert interpretation of dominant-feature comparison
- Well-known mark screening — which requires specialized research beyond standard database queries
- Multi-class or international filing strategy — including coordinating a single mark across many Nice classes or through Madrid Protocol international registration

Frequently Asked Questions
Do I have to search before registering a trademark in China?
No, it is not a legal requirement. Applicants can file directly without a prior search. However, because China follows a first-to-file system, skipping the search significantly raises the risk of rejection, which wastes official fees and delays brand entry.
Do I need an account to search the China Trademark Office database?
Yes. The Trademark Similarity Search module requires a registered, logged-in account. Since 2026, the online query system connects to the National Intellectual Property Public Service Platform’s unified single sign-on system[4].
How do I search a figurative (logo) trademark in China?
Since May 22, 2026, applicants can use the image-based search tool on the China Trademark Office website. Under Trademark Similarity Search, select the image-search method and upload the logo file. Results are for reference only[6].
Does a clear trademark search guarantee registration success?
No. Search results carry no legal binding force. Even when no prior conflicting mark appears, an application can still be rejected for lack of distinctiveness, prohibited content, or an undisclosed well-known mark conflict.
Is trademark searching in China free?
The official China Trademark Office search tools are free for public use[1]. Professional, in-depth clearance searches, such as well-known mark screening or figurative mark analysis performed by a licensed agency, typically involve a service fee.
How can a foreign company search and register a trademark in China?
Foreign companies may use the official China Trademark Office website to search marks free of charge. For filing, foreign applicants without a domicile or business establishment in China must appoint a licensed trademark agency under Article 11[7]. China is also a Madrid Protocol member, allowing international registration designating China.
What should a complete trademark search in China cover?
A thorough search should review valid registered marks, marks under preliminary approval publication, pending applications, marks under opposition, cancellation, or invalidation, and well-known marks, which are screened separately since they are not limited to a single product class.
Conclusion
With more than 53 million active registered trademarks now on file in China[5], running a search before you commit to a brand name is no longer optional in any practical sense — even though it remains technically optional in law. The May 2026 image-search launch has made checking figurative marks meaningfully easier, but every official tool still comes with the same caveat: a clean search result is a risk indicator, not a registration guarantee. Combining the official CNIPA search systems with a professional clearance review — particularly for well-known mark screening, figurative marks, or foreign-entity filings — remains the most reliable way to protect your brand before you file.
