How to Use CNIPA Trademark Search Online Like a Professional
Key Facts
| Fact | Detail |
|---|---|
| Official search system | Free public tool run by CNIPA’s Trademark Office at sbj.cnipa.gov.cn; account registration required |
| Governing principle | China follows “first-to-file,” so search results guide risk assessment before filing, not a legal precondition to it |
| 2026 update | AI-powered “search by image” function launched officially on May 22, 2026 |
If you’re preparing to file a trademark in China, the CNIPA trademark search system is the first tool you should open — not the last. China operates on a strict first-to-file basis, so this guide covers how to access the official portal, which search mode to use, how to read results, and the mistakes that trip up even experienced filers — plus the 2026 AI image search feature and the legal provisions behind it.
1. What Is CNIPA Trademark Search and Why It Matters
A Free, Official Public Database
The CNIPA trademark search system is China’s only official, government-operated platform for checking trademark application and registration records, maintained by CNIPA’s Trademark Office and open to the public at no charge [1]. Every trademark filed in China — pending, registered, opposed, or cancelled — eventually surfaces here, making it the most authoritative source before you commit to a filing strategy.
Why First-to-File Makes Search Non-Negotiable
Unlike jurisdictions that recognize trademark rights based on first use, China’s Trademark Law grants rights to whoever files first. This means a brand with years of use and reputation abroad can still lose the China market to a local party that files a nearly identical mark ahead of them. YCIP has covered this dynamic in depth in its guide to why China’s first-to-file system matters for foreign brands. Search is the practical countermeasure: it lets you see who has already staked a claim to a name, logo, or slogan before you spend money developing packaging, marketing, or a full application around it.
What Search Can — and Cannot — Tell You
It’s important to set expectations correctly. Running a search is not a legally mandated step before filing — an applicant can submit an application without ever searching first. But skipping this step is expensive. Even when a search turns up no identical or similar prior mark, an examiner can still reject an application later for reasons a basic search won’t catch, such as lack of distinctiveness or conflict with prohibited terms. A clean result lowers your risk; it doesn’t guarantee approval. Treat it as a cost-reduction filter, not a certification of registrability. See YCIP’s complete guide to China trademark search for more.
2. Where to Access It: Official Portals
The Three Legitimate Entry Points
Because so many third-party websites claim to offer “China trademark lookup,” it’s worth knowing exactly where the real data originates. All legitimate search tools — including paid monitoring platforms — ultimately pull their records from CNIPA’s own systems. There are three official access routes:
| Access Point | URL | Notes |
|---|---|---|
| China Trademark Website (main entry) | sbj.cnipa.gov.cn/sbj/sbcx/ | Click “Trademark Search” to proceed |
| Trademark Online Search System (direct) | wcjs.sbj.cnipa.gov.cn | Requires account registration and login |
| National IP Public Service Platform | ggfw.cnipa.gov.cn | Navigate via “Information Services” → “Trademark” |
Registration Is Required, But Search Is Free
To use the Trademark Similarity Search function specifically, users must register an account, which typically requires identity verification for individuals or business credentials for companies [2]. This registration step does not carry any fee — CNIPA does not charge for search access. It exists mainly to prevent automated scraping and support account-based features like saved searches.
Why the Official Channel Matters
The system’s own disclaimer notes that its data is not updated in real time and carries a lag, so results are for reference only and are not legally binding [3]. That caveat applies equally to any third-party tool, since none of them can be more current than the source database they scrape. Some paid monitoring platforms add convenience features — alerts, dashboards, or bulk exports — but the underlying records are identical to what you’d find by searching CNIPA directly. For foreign applicants without a China-based entity, note also that under Article 10 of the Trademark Law, an applicant may handle trademark matters directly or through an authorized trademark agency — a distinction covered further in the legal section below. If you’d rather have a licensed agency run and interpret the search on your behalf, YCIP’s trademark and copyright services team handles this as part of standard filing preparation, and can also flag ambiguous results that a first-time user might read too optimistically.
3. Step-by-Step: How to Run a Search
Step 1 — Access and Log In
Go to the China Trademark Website at sbj.cnipa.gov.cn and click “Trademark Search.” You’ll be prompted to accept the terms of use, which redirects to a login/registration screen. First-time users must register an account, a process that includes identity verification, before search functions unlock.
Step 2 — Choose a Search Type
Once logged in, you’ll see five distinct search functions, each suited to a different question. We break these down in detail in the next section, but at this stage you simply select the one matching your goal — most commonly, Trademark Similarity Search for pre-filing conflict checks.
Step 3 — Enter Your Search Criteria
You’ll need to supply:
- International class number (mandatory) — a number from 1 to 45, based on China’s Classification Table of Similar Goods and Services
- Search method — choose from Chinese characters, Pinyin, English, numerals, initial characters, graphic code, or image-based search
- The mark itself — the wordmark, name, or graphic elements you intend to file
Step 4 — Read and Interpret the Results
The system returns a list of registered marks and marks under preliminary examination announcement that match or resemble your input. For each result, review:
- The trademark name or graphic design
- Its current status — pending, registered, or expired
- The rights holder
- The specific goods or services covered
- The class and similar subgroup it falls under
Don’t stop at a surface read of the list. A result showing “registered” in your exact class is an obvious red flag, but marks in adjacent similar subgroups, or marks currently under opposition, deserve equally close attention — a point we return to in the mistakes section below. For applicants who want a second set of eyes on ambiguous results, YCIP’s team routinely reviews raw CNIPA search output as part of its consultation and litigation support services.
4. The Five Search Modes and When to Use Each
| Search Mode | What It Does | Best Used For |
|---|---|---|
| Trademark Similarity Search | Finds registered or preliminarily approved marks identical or similar to your proposed mark | Pre-filing conflict checks (most common use) |
| Comprehensive Search | Multi-field search by trademark name, applicant, or registration number | Researching a specific mark or a competitor’s full portfolio |
| Status Search | Shows the current legal status of a specific application or registration | Monitoring the progress of your own pending applications |
| Trademark Gazette Search | Searches preliminary approval announcements and registration announcements | Watching the opposition window, tracking competitor filings |
| Goods/Services Item Search | Looks up standardized names for goods and services | Preparing accurate application documents |
Classes Alone Aren’t Enough
China applies the 45-class Nice Classification system, but layers a China-specific “similar subgroup” structure on top of it. Two marks can sit in the same Nice class yet belong to different subgroups — or, more dangerously, sit in different classes while occupying subgroups considered similar enough to conflict. Searching only at the broad Nice-class level routinely misses these subgroup-level conflicts, which are often where real rejection risk hides.
A Practical Search Pattern
For a thorough pre-filing check, run the Trademark Similarity Search against your target class and its neighboring subgroups separately, rather than relying on a single query. Combine this with a Comprehensive Search on the exact wordmark to catch any applicant-specific patterns, such as a competitor systematically filing variations of your brand name. It also pays to repeat the same query in each script or format you intend to use — English, Pinyin, and Chinese characters can each surface different prior marks. YCIP’s guide to mastering CNIPA trademark search walks through this layered approach with worked examples, and the team’s database search guide covers how to interpret subgroup codes specifically.
5. New in 2026: AI-Powered “Search by Image” Function
What Launched and When
On May 22, 2026, CNIPA’s Trademark Office officially launched an AI-powered “search by image” (以图搜图) function inside the Trademark Online Search System, announced via its official notice on the rollout [4]. This is the most significant functional upgrade to the search platform in recent memory, and it directly addresses a long-standing pain point: searching for graphic or logo-based marks used to rely almost entirely on manually assigned image classification codes, which are inconsistent and easy to miss.
How to Use It
- Open the Trademark Online Search System on the China Trademark Website
- Click “Trademark Similarity Search”
- Under the search-method options, select “Image Retrieval” (以图搜图)
- Upload your proposed logo or graphic mark in the search-image field
- Enter the relevant international class number
- The system runs an AI-driven similarity comparison and returns matching or near-matching results
Supported file formats are PNG, JPEG, and JPG, with a maximum file size of 2MB per upload [4].
Why This Matters Beyond Convenience
The feature is built on large-model AI technology and represents part of CNIPA’s broader push to fuse trademark examination with artificial intelligence, including a new image-recognition framework that parses design elements, classifies mark types, extracts visual features, and locates the dominant portion of a logo [4]. For foreign brands whose primary asset is a logo or symbol rather than a wordmark, this closes a search gap that previously required either painstaking manual review or a paid third-party image-search tool.
A Professional Caveat
Treat AI image-search output as a starting point, not a legal conclusion. Determining whether two graphic marks are confusingly similar under Chinese trademark examination practice involves established legal tests — isolated observation, overall comparison, and comparison of the dominant portion of each mark. An AI similarity score does not replace that analysis. Where a search returns close visual matches, or where the result is ambiguous, pairing the tool with a professional review is the safer path — something YCIP regularly handles through its trademark and copyright services.
6. Legal Basis: What the Trademark Law Says About Search
The Framework Behind the System
Trademark search doesn’t exist in a legal vacuum — several provisions of China’s Trademark Law shape how the process works and who can use it. The table below summarizes the provisions most directly relevant to search and pre-filing preparation.
| Provision | Key Content | Relevance to Search |
|---|---|---|
| Article 10 | Applicants may handle trademark registration and related matters directly or through an authorized trademark agency | Confirms the option to self-file, though most foreign applicants use an agency in practice |
| Article 11 | Foreign individuals or enterprises are handled according to international treaties China has joined, the principle of reciprocity, or this Law | Sets the special framework governing cross-border and foreign-applicant search and filing |
| Article 13 | The trademark administration department under the State Council is directed to strengthen the informatization and intelligent development of its public trademark services and to release trademark information completely, accurately, and promptly | Forms the legal basis for the search system’s existence and its data-disclosure obligations |
| Article 28 | Sets out the examination and approval procedure for trademark registration applications | Explains why a clean search result doesn’t guarantee approval — full examination happens afterward |
| Article 33 | Allows opposition to be filed against marks published under preliminary examination announcement | Gives the Trademark Gazette Search function its legal significance |
Requirements Specific to Foreign Applicants
Under Article 11, foreign individuals or enterprises without a habitual residence or place of business in China must appoint a legally established trademark agency to handle their filing [5]. This doesn’t restrict who can run a search — the portal is open to anyone — but it does mean the actual filing for most foreign applicants routes through a licensed agency by law, not convenience.
Search Results Are Reference, Not Guarantee
None of these provisions make search a mandatory precondition to filing, and none make a favorable result legally binding on the examiner. The system’s authority comes from the completeness and accuracy obligations in Article 13, not from any guarantee of outcome — which is why YCIP consistently frames search as risk reduction rather than risk elimination, including in its China trademark registration guide for foreign companies.
7. Common Mistakes to Avoid When Using CNIPA Trademark Search
| Mistake | Consequence | Correct Approach |
|---|---|---|
| Searching only the English name, skipping the Chinese version | Misses Chinese-character or Pinyin conflicts entirely | Search English, Chinese-character, and Pinyin versions together |
| Searching only the broad Nice class, ignoring similar subgroups | Misses conflicts sitting in adjacent similar subgroups | Search the target class and its neighboring subgroups separately |
| Checking only “registered” marks | Misses marks under preliminary announcement or still in examination | Review valid registrations, gazette announcements, and pending applications together |
| Skipping a well-known mark check | Cross-class protection for well-known marks can still trigger rejection | Run a dedicated well-known trademark search |
| Ignoring recently cancelled or revoked marks | Marks within their post-cancellation grace period can still block a new filing | Check for marks in the cancellation/revocation grace period |
| Relying entirely on the free official search | The official tool is a first-pass filter and can miss phonetic or visual near-misses | Pair official search with professional review for nuanced similarity risk |
Why These Mistakes Are So Common
Most of these errors happen not from carelessness but from treating the search tool as a simple lookup rather than a multi-layered investigation. A single query on a single field will almost always return a result — the danger is mistaking a narrow result for a comprehensive one. Foreign applicants unfamiliar with the subgroup system or the Chinese-character dimension of their own brand name are especially exposed, since these are the layers a native English-language search instinct tends to skip.
Building a Search Checklist
A disciplined pre-filing search should touch all of the following before you file: the exact wordmark in every language and script you intend to use, the target class plus adjacent subgroups, the Trademark Gazette for recent announcements, and a well-known mark check where your brand has any public profile. If any of these turns up an ambiguous result, that’s the point to bring in a professional opinion rather than push forward. YCIP’s guide on checking whether your brand name is available in China walks through this checklist in more detail, and the firm’s quote request form is a fast way to get a professional read on ambiguous results.
8. CNIPA Trademark Search in 2026: Key Statistics & Trends
The Numbers at a Glance
| Metric | Figure | Period |
|---|---|---|
| National valid registered trademarks | 50.816 million | End of 2025 [6] |
| National valid registered trademarks | Over 51.52 million | As of March 2026 [7] |
| Valid registered trademarks | 53.108 million | End of January 2026 [8] |
| New trademark registrations approved | 2.055 million | H1 2026 [9] |
| Average trademark examination cycle | Approximately 4 months | 2025–2026 [6] |
| Examination/opposition/review spot-check pass rate | Over 97% | 2025–2026 [6] |
| Estimated overall rejection rate | Roughly one-third to over 40% (industry estimate, not an official CNIPA figure) | 2026 [10] |
What the Growth in Registered Marks Means for You
China’s pool of valid registered trademarks grew from roughly 50.8 million at the end of 2025 to over 51.5 million just three months later [6][7], and had already reached 53.1 million by the end of January 2026 alone according to CNIPA’s own monthly statistical release [8]. Read together, these figures point to a market where straightforward, easily-available brand names are becoming scarce, and where any given search is increasingly likely to surface at least one close prior mark. That trend alone justifies running a layered search rather than a single quick lookup.
Rejection Risk Is Real and Rising
Industry estimates place the overall rejection rate at roughly one-third to over 40% in 2026, with popular classes running higher [10]. This figure comes from industry commentary rather than an official CNIPA release, so treat it as directional — but even conservatively, a meaningful share of applications fail for reasons search alone won’t catch, like distinctiveness objections. It reinforces the point: search reduces risk, it doesn’t eliminate it.
Examination Speed Remains a Bright Spot
Despite rising filing volume, CNIPA has held its average examination cycle at roughly four months, with pass rates above 97% [6]. For applicants, rising competition paired with fast, stable examination means the search-and-file window matters more than ever — a name available today may not be available in four months if a competitor files first.
Frequently Asked Questions
Is CNIPA trademark search free?
Yes — free public use, with account registration required.
Do I need to register an account?
Yes, identity verification is required for Similarity Search, though searching carries no fee.
Can foreigners use CNIPA trademark search?
Yes, the portal is open to anyone. Filing an application requires foreign applicants without a China presence to appoint a licensed agency under Article 11.
How often is CNIPA trademark data updated?
Periodically, with a “current as of” date shown. Re-run your search shortly before filing.
Similarity Search vs. Comprehensive Search?
Similarity Search finds conflicting marks. Comprehensive Search looks up a specific mark, applicant, or registration number.
I found a conflicting trademark — now what?
Assess the conflict’s severity, weigh options like modifying the mark or adjusting the goods/services scope, and get a professional opinion before filing.
Do search results guarantee approval?
No. An application can still be rejected at examination even after a clean search result.
What’s new in 2026?
AI-powered “search by image,” launched May 22, 2026. From July 1, 2026, most agency filings also route through the online system electronically.
Conclusion: Make Search Your First Move, Not Your Last Check
CNIPA’s trademark search system is free, official, and increasingly capable — especially with the 2026 addition of AI image search — but it was never designed to replace professional judgment. With registered trademarks past 51 million and rejection risk near one in three applications by industry estimates, a single quick lookup is no longer a reliable safety check. Brands that protect themselves successfully search early, across every dimension of their mark, and bring in professional review before they file.
