Use a China Trademark Availability Checker Before Filing
| Key Fact | Figure | Source Period |
|---|---|---|
| Trademark applications filed nationwide | 6.97 million | Full year 2024 |
| Valid registered trademarks in China | 49.88 million | As of end of 2025 |
| Long-term rejection / partial-rejection rate | 40%+ | CNIPA public data |
If you are planning to register a brand name in China, a trademark availability checker is your starting point, not your finish line. It tells you whether an identical or similar mark already exists in the same class. It does not tell you whether your mark will survive examination. This article explains what these tools actually check, why skipping this step is risky, how to run a search yourself on the official government portal, and what additional legal analysis a checker cannot replace.
1. What Is a China Trademark Availability Checker?
A China trademark availability checker is a search tool — usually the official government portal, sometimes an authorized third-party platform — that lets you look for identical or similar marks already filed on the same or similar goods and services. In China, this function sits with the China National Intellectual Property Administration (CNIPA) and its Trademark Office. Our complete guide to China trademark search covers the broader search landscape if you want more background before diving into a single tool.
Two Official CNIPA Search Portals
| System | Access | Core Function |
|---|---|---|
| Trademark Online Search System | wcjs.sbj.cnipa.gov.cn | Similarity search, comprehensive search, status search, gazette search, goods/services classification search |
| Trademark Open Data System | sbj.cnipa.gov.cn | Bulk download of the full historical and incremental trademark dataset |
China’s official trademark database dates back to the first issue of 1980 and is maintained directly by the Trademark Office [1]. That depth of coverage is one reason foreign applicants are advised to check the government portal directly rather than rely solely on third-party aggregators — a point we expand on in our China trademark database search guide.
What Each Search Module Does
The system is organized into five functional modules:
- Similarity search — checks whether an identical or similar mark already exists on the same or similar goods, searched by graphic elements, text, or both
- Comprehensive search — looks up a specific mark by application number, mark name, or applicant name
- Status search — tracks where an application sits in the examination process, by application or registration number
- Gazette search — retrieves the electronic trademark gazette listings
- Goods and services classification search — searches by international class or similar group code
For applicants running their own preliminary screening, our step-by-step CNIPA search walkthrough demonstrates how these five modules work together in practice.
Account Registration Requirement
Since October 22, 2023, several sections of the online system — including trademark gazette, registration certificate verification, public document access, and online search — require account registration before use [2]. This is a procedural detail that trips up many first-time foreign applicants, so budget a few extra minutes for account setup before you start searching.
2. Why Availability Search Is Non-Negotiable Before Filing
China’s Trademark Filing Volume
China’s trademark system processes an enormous volume of activity every year. In 2024 alone, applicants nationwide filed approximately 6.97 million trademark applications, while roughly 4.78 million marks were registered [3]. As of the end of 2025, the total stock of valid registered trademarks in China reached approximately 49.88 million [1], and that number has continued climbing through 2026. Roughly one in every four market entities in China now holds at least one registered trademark [3]. Put simply: the pool of short, memorable, industry-appropriate names is shrinking fast.
The Rejection Rate Reality
Against that backdrop, the overall pass rate for trademark applications has been declining — from around 82% in 2022 to roughly 68.6% in 2024 [3]. Multiple industry analyses citing official CNIPA data place the long-term rejection and partial-rejection rate at 40% or higher [4]. In competitive sectors such as food service and apparel, pass rates can fall below 45% [3]. Even after a rejection, the odds of winning on reconsideration are limited — around 23.3% by one industry estimate based on CNIPA figures [3].
What This Means for Your Application
A 40%+ rejection rate is not evenly distributed — it concentrates on applicants who filed without adequate prior search. Running an availability check before you file does not guarantee approval, since absolute grounds like distinctiveness are a separate risk category, but it directly reduces your exposure to the single largest cause of rejection: conflict with a prior mark. If you’re weighing whether your business name specifically clears this bar, see is your brand name available in China for a more scenario-based walkthrough, and our registration guide for foreign companies for how this fits into the full filing timeline.
3. How to Use the Official CNIPA Search System
Step-by-Step Instructions
- Access the official system. Go directly to wcjs.sbj.cnipa.gov.cn, or navigate there through the National Intellectual Property Public Service Platform under “Information Services” → “Trademark.”
- Register and log in. Since October 22, 2023, you need a registered account through the platform’s unified identity authentication system before you can search.
- Choose your search mode. Pick similarity search, comprehensive search, status search, or gazette search based on what you need to know.
- Enter your search terms. The system accepts Chinese characters, pinyin, English, numbers, initial characters, and graphic elements — six input types in total, and it supports fuzzy matching, so searching “蓝天” can surface variants like “蓝天之韵” as well.
- Review and interpret the results. Check whether any returned marks are identical or similar, and whether they sit in the same or a similar goods/services class as your intended filing.

Choosing the Right Search Mode
| Search Mode | Best Used For |
|---|---|
| Similarity search | Checking whether your proposed mark conflicts with an existing mark on the same or similar goods |
| Comprehensive search | Pulling full details on a specific known mark |
| Status search | Tracking the examination progress of a mark already filed |
| Gazette search | Reviewing official gazette publications |
If you’re comparing the government portal against paid third-party tools, our comparison of trademark search engines in China breaks down where each option is strongest.
4. The Legal Basis Behind Availability Search
Availability search exists because China’s Trademark Law sets out specific, codified grounds for refusal. Understanding the underlying provisions helps you read your search results the way an examiner would, rather than just scanning for exact-name matches.
Absolute Grounds for Refusal
Trademark Law, Article 9: “The trademark for which registration is applied shall have distinctive features so as to facilitate identification, and shall not conflict with the lawful rights previously obtained by others.” [5]
Article 10 further bars specific categories of signs — such as national names, national flags, and similar restricted symbols — from ever functioning as a trademark, regardless of prior conflicts. These are called absolute grounds: defects in the mark itself, tied to distinctiveness, non-functionality, and public interest, rather than any conflict with a third party’s rights [5].
Relative Grounds: Conflicts With Prior Marks
Trademark Law, Article 30: An application that conflicts with, or is identical or similar to, an already registered or preliminarily approved trademark on the same or similar goods shall be rejected by the Trademark Office and not published. [5]
Article 31 adds the “first-to-file” rule: when two or more applicants file identical or similar marks on the same or similar goods, the mark filed earliest receives preliminary approval and publication [5]. These are relative grounds — refusals rooted in a conflict with someone else’s prior right, which is exactly what an availability search is designed to surface. For a deeper breakdown of how rejections under these articles play out and how to respond, see our guide to China trademark rejection reasons and solutions.
Why This Distinction Matters for Search Strategy
An availability checker is built to catch relative-ground conflicts — identical or similar prior marks. It is not built to evaluate absolute grounds like distinctiveness, deceptiveness, or restricted symbols, and it cannot flag China’s first-to-file dynamics, including bad-faith pre-registration by unrelated third parties. Our guide on why China’s first-to-file system matters for foreign brands explains why this filing-order rule makes early, well-informed search especially important for companies entering the China market for the first time.
5. How Examiners Judge Similarity
Once your search turns up a potential conflict, the next question is whether it counts as legally “similar” under China’s standards. CNIPA’s Trademark Examination and Adjudication Standards lay out the framework examiners use [6].
Identical vs. Similar Marks
A mark is considered identical when two marks are visually indistinguishable, or, for sound marks, aurally indistinguishable. A mark is considered similar when the characters’ form, pronunciation, or meaning — or a graphic mark’s composition, design, and overall presentation — resemble a prior mark closely enough that relevant consumers could mistake the source of the goods. This standard also extends to three-dimensional shapes and color combinations [6].
The Four-Factor Judgment Method
Examiners do not simply compare marks letter by letter. The Standards direct a structured comparison:
- Overall impression combined with dominant-element comparison — looking at the mark as a whole, then isolating its most distinctive part
- The average attention level of the relevant public — judged from an ordinary consumer’s perspective, not an expert’s
- Distinctiveness and fame of the marks involved — a well-known mark receives broader protection
- The degree of connection between the goods or services — closer product relationships increase confusion risk
Special Situations Worth Knowing
Two edge cases come up often for foreign applicants. First, a mark that fully incorporates or imitates a prior mark with high recognition or strong distinctiveness can be judged similar if consumers might assume it belongs to the same brand family — even without an exact match. Second, for composite marks, similarity is assessed component by component: if the Chinese-character portion, the foreign-language or numeric portion, or the graphic portion is separately similar to a prior mark, that alone can trigger a similarity finding [6]. If your proposed mark leans on an existing brand name or common phrase, our guide on how to prove trademark distinctiveness in China is a useful next read.
6. Limitations of the Free Official Tool
The official CNIPA search system is the right starting point, but it was built for basic public screening, not for a full legal opinion. Applicants who treat a clean search result as a green light are skipping several real gaps.
Where the Free Tool Falls Short
| Limitation | What It Means in Practice |
|---|---|
| Data lag | A blind-search window of roughly six to eight months means recently filed applications may not yet appear |
| Mechanical matching only | The system matches text and graphics literally; it cannot apply the four-factor legal similarity test |
| Weak graphic-mark search | Classification coding for design elements limits accuracy and completeness for logo-based marks |
| No legal analysis | The tool does not assess distinctiveness, deceptiveness, or other absolute-ground risks |
| Language barrier | The primary interface is in Chinese, which is difficult for applicants without Chinese-language support |
| No bad-faith detection | The system cannot flag trademark squatting or hoarding patterns tied to a proposed mark |
The Blind Spot That Matters Most
The six-to-eight-month blind-search window is the limitation with the biggest practical consequence. Because China operates on a first-to-file basis under Article 31, a mark filed shortly before yours — but not yet visible in the database — can still defeat your application even though your own search came back clean. This is also the mechanism bad-faith filers exploit: pre-registering names they anticipate a foreign brand will want. See our guide on trademark squatting in China for how this risk plays out and what recourse exists if it happens to you.
Why This Isn’t a Reason to Skip the Free Search
None of this makes the free tool worthless — it remains the fastest way to catch the most obvious conflicts before you invest further time or fees. It simply means a clean result is a preliminary signal, not a legal clearance. Treat it as step one of a larger process, not the whole process.
7. A Fuller Evaluation Process — Beyond the Free Checker
YCIP recommends a four-step evaluation sequence for applicants who want more confidence before filing, particularly for foreign brands entering the China market for the first time.
Step 1: Run Your Own Preliminary Search
Start with the official CNIPA search system to screen out obvious conflicts and get familiar with what’s already registered in your class.
Step 2: Get a Professional Deep-Search Analysis
A licensed trademark agent can go further than the public interface: cross-checking classification data, factoring in the blind-search window, and running a more thorough graphic-element search than the free tool supports on its own.
Step 3: Complete a Legal Risk Assessment
This is where Articles 9, 30, and 31 get applied to your specific mark — evaluating similarity against prior marks, checking for absolute-ground issues, and assessing overall registrability before you commit to filing fees and examination timelines.
Step 4: Set a Filing Strategy
Based on the assessment, you decide whether to file as-is, adjust the design to increase distinctiveness, or prepare contingency plans — such as a reconsideration request or opposition response — in case of a partial rejection. Our complete guide to registering a trademark in China and cost guide are useful references once you’re ready to move from evaluation to filing. YCIP’s trademark and copyright services team, led by Peter H. Li, handles all four steps for clients directly.
Frequently Asked Questions
Is China trademark search free?
Yes. The China Trademark Office has offered free public search through the official China Trademark Website since December 26, 2005. Since October 22, 2023, you need to register an account to use the online search modules. Free search covers basic screening; a deeper legal analysis typically calls for a licensed trademark agency.
How do I check if a trademark name is already registered in China?
Log into the official China Trademark Website, open similarity search or comprehensive search, and enter the mark name, applicant name, or registration number. The system accepts Chinese characters, pinyin, English, numbers, initials, and graphic elements, with fuzzy-match support.
Does the China trademark search system have an English version?
The main search interface is Chinese-only. CNIPA’s English-language portal offers some statistics but not the full search function. Foreign applicants without Chinese-language support generally work through a licensed China trademark agency instead.
My search found a similar mark. Can I still register my trademark?
It depends on the closeness of the similarity, the classes involved, and how strong the prior mark is. An identical mark on identical or similar goods is very likely to be rejected under Article 30. A similar — but not identical — mark carries real risk but may still leave room for design adjustments, class changes, or a coexistence agreement. Get a professional risk assessment before deciding to proceed or walk away.
How high is the rejection rate for China trademark applications?
Industry analyses citing CNIPA public data put the long-term rejection and partial-rejection rate at 40% or higher, with the overall pass rate falling to roughly 68.6% in 2024. Competitive sectors such as food service and apparel see pass rates below 45%.
Conclusion
A China trademark availability checker is essential — and, on its own, incomplete. The official CNIPA system will catch the most obvious conflicts for free, but it can’t see recently filed applications during the blind-search window, can’t apply the legal similarity test examiners use, and can’t flag bad-faith filings aimed at your brand. With rejection rates running at 40% or higher and more than 49.88 million marks already registered, a preliminary self-search followed by a professional legal risk assessment is the difference between a smooth filing and a costly rejection.
