How to Perform a China Trademark Search Online Before Filing

Key Facts

If you are planning to sell products, open a factory, or license a brand in China, a trademark search is the single most important step before you file. China runs on a strict first-to-file system, which means the person or company who registers a mark first generally wins the rights to it, regardless of who used it first anywhere else in the world. Skip the search, and you risk months of wasted time, a rejected application, or worse: discovering that someone else already owns your brand name in China.

This guide walks foreign businesses through exactly how to search China’s trademark database online, what the results actually mean, and where the process still leaves gaps that only a professional review can close. We’ll also cover new tools the China National Intellectual Property Administration (CNIPA) rolled out in 2026, including an AI-powered image search for logos.

Why a Trademark Search Is Legally Necessary in China

China’s trademark system does not reward the first company to use a brand. It rewards the first company to file. As of June 15, 2026, China had 51,971,435 active registered trademarks on record^[1], and the total pool keeps growing every quarter. In the second quarter of 2026 alone (December 16, 2025 to June 15, 2026), CNIPA recorded 3,407,464 new applications and approved 2,004,489 registrations^[1]. With a database this large, the odds of an unintentional collision between your proposed mark and an existing one are no longer small — they are a routine part of filing in China.

China’s First-to-File System

Under first-to-file, ownership goes to whoever submits a complete, compliant application first — not whoever built the brand, launched the product, or has used the name for years overseas. Many foreign companies discover too late that a domestic party has already registered their exact brand name, sometimes in bad faith, a practice known as trademark squatting. Our guide on China’s first-to-file system and why it matters for foreign brands covers this risk in more depth, and our article on trademark squatting in China walks through what to do if someone has already claimed your name.

The Legal Basis for Trademark Searches

The requirement to search before filing is not just best practice — it is built into the law itself.

Trademark Law of the People’s Republic of China, Article 9: A trademark for which registration is applied must be distinctive and easily identifiable, and must not conflict with any prior legitimate right acquired by another party.

Trademark Law of the People’s Republic of China, Article 30: Where a trademark applied for registration does not conform to the relevant provisions of this Law, or is identical with or similar to a trademark already registered or preliminarily approved by another party on the same or similar goods, the Trademark Office shall reject the application and shall not publish it for opposition.

Article 30 is the provision that catches the majority of applications. Industry data indicates that more than 70% of failed trademark applications in China fail specifically because of similarity to an existing mark^[2] — which is precisely the risk a proper search is designed to catch before you pay filing fees and wait months for a rejection.

Trademark Law of the People’s Republic of China, Article 31: Where two or more applicants apply for registration of identical or similar trademarks on the same or similar goods, the Trademark Office shall approve and publish the application filed first.

Trademark Law of the People’s Republic of China, Article 4: Any malicious application for trademark registration that is not intended for use shall be rejected.

Article 4 has become more consequential in 2026. Since 2023, CNIPA has rejected approximately 1.273 million trademark applications and invalidated 3,351 registered marks for bad-faith or non-use filings^[8]. In late 2025, a draft amendment to the Trademark Law passed its first reading before the Standing Committee of the National People’s Congress, with the revision pushing further toward requiring genuine intent to use a mark before it can be registered^[3]. If passed, this will raise the bar even higher for applicants who cannot show real business need for the classes they file in. For a full walkthrough of the registration process under current law, see our China trademark registration process guide.

Rejection Rate Trends (2024–2026)

In practical terms, roughly one in three applications filed in China is rejected^[2]. Popular classes fare even worse: Class 35 (advertising, business management, and e-commerce) has reported approval rates below 20% in some datasets, and led all 45 classes with 186,700 new applications in the first quarter of 2026 alone^[6]. If your business touches e-commerce, retail, or marketing services, this class deserves particular attention during your search. Our guide to trademark rejection reasons and solutions breaks down how to respond if a rejection happens despite your search.

Official Channels for Searching Trademarks Online in China

Before comparing tools, it helps to know exactly who runs China’s trademark system and where the authoritative data actually lives.

China Trademark Office (CNIPA) and the China Trademark Website

Trademark matters in China are administered by the Trademark Office of the China National Intellectual Property Administration (CNIPA). The official public search portal is the China Trademark Website, at sbj.cnipa.gov.cn^[4], with the direct search tool located at wcjs.sbj.cnipa.gov.cn. This is the only source of authoritative, government-verified trademark data in China. Any third-party tool you use should ultimately be checked against this system.

Four Official Search Modes

Most foreign applicants will rely primarily on similarity search during the pre-filing stage, then use status search to track an application after submission. Our China trademark database search guide and guide to mastering CNIPA trademark search go deeper into how to use each mode effectively.

The 2025 Unified Login System Change

This is a detail that trips up many overseas applicants who used the system before late 2025. As of December 19, 2025, at 8:00 AM, the online trademark query system was integrated into the National IP Public Service Platform’s Unified Identity Authentication System, and accounts registered under the old system stopped working^[4]. Anyone searching or filing today must first register a new account and complete real-name verification at sso.cnipa.gov.cn. Users who have not completed real-name verification cannot access the online trademark application system. Budget extra time for this step if you have not used the platform recently — verification for foreign applicants can take longer than for domestic ones, which is one reason many businesses choose to route filings through a local agent instead. See our overview on China trademark registration for foreigners for what that process involves.

Step-by-Step: How to Search on the Official CNIPA System

Once your account and verification are in place, the actual search process follows a consistent sequence.

Step 1: Access the Site and Log In

Open sbj.cnipa.gov.cn (the China Trademark Website) and click through to “Trademark Search” (商标查询) to reach the online query system. Log in using your Unified Identity Authentication System account.

Step 2: Choose Your Search Type

Select the mode that fits your need — similarity search for pre-filing checks, comprehensive search for precise lookups by registration number or applicant, or status search to check where an existing application stands.

Step 3: Enter Search Terms

In the similarity search interface, enter the proposed trademark name. For word marks, search every meaningful variant separately: the full Chinese name, an abbreviated form, the Pinyin romanization, and any phonetic or homophone equivalents a Chinese consumer might associate with your brand. For graphic marks, you can enter a design element code, or use the image search feature described in the next section.

Step 4: Select the Correct Nice Classification

China follows the international Nice Classification system, with 45 classes total — Classes 1 through 34 cover goods, and Classes 35 through 45 cover services. A search limited to only your core business class is not enough; related and defensive classes matter too, since squatters frequently target adjacent categories a legitimate brand owner hasn’t yet claimed.

Step 5: Review the Results List

The system returns a list of matching or similar marks, including the trademark name, registration number, class, applicant, and current legal status. This is the point where interpretation becomes critical — a topic covered in detail later in this guide.

Key limitations to keep in mind at every step:

• Official database updates lag by 1 to 3 business days.
• Applications filed in the most recent six months may not yet appear in the public database.
• Search results are for reference only and carry no legal binding effect.

New in 2026 — “Search by Image” for Logo and Design Trademarks

On May 22, 2026, CNIPA’s Trademark Office officially launched a “Search by Image” (以图搜图) function within the China Trademark Website’s online query system^[5]. This is one of the most useful updates for foreign brand owners in years, because graphic and logo trademarks have historically been the hardest category to search — text-based near-duplicates are relatively easy to catch, but visual similarity has always required a trained eye or expensive professional review.

How the Feature Works

1. Go to the China Trademark Website’s online query system and select “Trademark Similarity Search.”
2. Under “Search Method,” choose “Search by Image.”
3. Upload your logo file. The system accepts PNG, JPEG, and JPG formats, with a maximum file size of 2MB^[5].
4. The system runs an AI-driven visual similarity comparison against the existing trademark database.

Why It Matters for Foreign Brand Owners

According to CNIPA’s official notice, the tool was built on the Trademark Office’s data and large AI models specifically to solve the long-standing difficulty of searching graphic trademarks, and is intended to meaningfully lower the technical barrier to doing so^[5]. That said, CNIPA itself is explicit that results are for reference only — final determinations on visual similarity still require review by a trademark examiner, since factors like color, composition, and overall impression involve subjective judgment that current AI tools cannot fully replace^[5]. If your brand relies heavily on a logo, icon, or stylized wordmark, this tool is a strong starting point, but it should not be your only check. Our comparison of the best trademark search engines in China covers additional tools that can supplement this new feature.

How to Interpret Your Search Results

Getting a results list back from the China Trademark Website is only half the job. Reading it correctly is what actually protects you from a rejection.

What Each Status Means

Five Points Every Reader Should Understand

• Search for similar marks, not just identical ones. Marks that merely resemble yours can still trigger a rejection under Article 30.
• Always search by class. The same trademark name can be legitimately owned by different companies in different classes.
• Well-known marks are not limited by class. A trademark recognized as “well-known” (驰名商标) can receive cross-class protection beyond its registered categories.
• Cancelled or invalidated marks can still be obstacles if they fall within a statutory grace period.
• “No results found” does not mean “available.” It may simply reflect a data lag or the blind spot period described below.

The Six-Month Blind Spot

This is the single most misunderstood limitation of any China trademark search — official or third-party. Applications submitted within the most recent six months may not yet be visible in the public database^[4]. If someone filed a conflicting mark five months ago, your search may return “no results” today, but that earlier application will still take priority once it appears in the system, retroactive to its original filing date. No amount of careful searching on your end can eliminate this risk entirely — it is a structural gap in the public system itself, which is why many businesses pair a self-search with a professional risk assessment before filing. Our article on what to check before filing a China trademark expands on how to manage this exposure.

Common Mistakes Foreign Applicants Make

Even diligent applicants fall into predictable traps. Here are the five most common, based on patterns we see in failed applications.

Mistake 1: Searching Only the Exact Brand Name

The error: Entering only the full brand name and skipping abbreviations, Pinyin, homophones, and visually similar characters.

The fix: Search the full name, shortened form, Pinyin romanization, phonetic equivalents, the English counterpart, and any characters that look similar in stroke pattern.

Mistake 2: Ignoring or Under-Selecting Classification

The error: Searching with no class selected, or checking only the primary business class.

The fix: Cover every relevant class plus reasonable defensive classes. Remember China’s system spans all 45 international classes — 34 for goods and 11 for services.

Mistake 3: Treating Search Results as Legally Binding

The error: Assuming an official search result is the same as an examiner’s final ruling.

The fix: Remember that CNIPA’s own system states results are for reference only^[4]. Final similarity determinations are made by a human examiner during substantive review.

Mistake 4: Overlooking the Blind Spot Period

The error: Concluding a mark is available simply because the search returned nothing.

The fix: Understand that marks filed in the past six months may not yet be visible, and factor that uncertainty into your filing decision.

Mistake 5: Using Unofficial or Unverified Search Platforms

The error: Relying on unofficial or copycat websites for search results.

The fix: Use the official China Trademark Website (sbj.cnipa.gov.cn) as your primary source, and verify any third-party tool’s results against it. Our guide on how to check if your brand name is available in China outlines a safer verification workflow.

Official Search vs. Third-Party Tools vs. Professional IP Agents

Once you understand the mechanics, the next decision is which resource to rely on — and for most businesses, the honest answer is a combination of all three at different stages.

In practice, most experienced applicants use the official system or a reputable third-party tool for an initial self-check, then bring in a professional agency before the actual filing to get a registrability opinion that accounts for the blind spot and for nuanced similarity judgments a non-specialist could miss. If you’re weighing whether that step is worth it for your situation, our article on why hiring a China trademark lawyer is essential for your business lays out the trade-offs in more detail, and our trademark and copyright services page outlines exactly what a full search and filing engagement includes.

What to Do After Your Search — Next Steps

Your next move depends entirely on what the search turned up.

Scenario 1: No Identical or Similar Marks Found

• You can move forward with preparing your formal application.
• Remember that blind spot risk still exists even with a clean result.
• A formal registrability analysis from a professional agency before filing is still the safest next step.

Scenario 2: Identical or Highly Similar Marks Found

• The risk of rejection on a direct filing is very high.
• Consider modifying your design or wordmark to add distinctive elements.
• Consider adjusting your target classes to avoid the conflict.
• Evaluate whether a coexistence agreement or purchase of the prior mark is realistic. Our guide on the secondary market for IP transfers in China touches on how these negotiations typically work.

Scenario 3: Partial Similarity, Outcome Unclear

• This calls for a professional similarity analysis from a qualified attorney.
• You may still choose to file while preparing a response strategy in case of an office action.
• Keep in mind the average examination cycle is roughly 4 months^[6], so build that timeline into your product launch or market entry plan. If a rejection does arrive, our guide to understanding a CNIPA rejection notice and trademark appeal timeline guide explain what happens next.

Frequently Asked Questions

Is a China trademark search free?

Yes. The official China Trademark Website, operated by CNIPA’s Trademark Office, offers similarity search, comprehensive search, status search, and gazette search completely free of charge^[4]. Some third-party platforms offer free basic lookups too, though in-depth analytical reports typically carry a fee.

How often is the CNIPA database updated? Is there really a blind spot?

Yes. Data on the China Trademark Website is not real-time — updates lag by 1 to 3 business days. More importantly, applications submitted within the most recent six months may not yet be entered into the public database. This gap, often called the “blind spot period,” is a structural limitation that no search — official or third-party — can fully eliminate. Once an application filed during this window is entered, its priority date still retroactively applies to the original submission date^[4].

How do I search a graphic trademark (logo) in China?

There are three main approaches: use the official Search by Image function launched May 22, 2026 (upload a PNG, JPEG, or JPG file under 2MB for an AI-driven similarity comparison); search using the internationally standardized Vienna Classification design element codes; or commission a professional agency to run a full graphic trademark search and analysis^[5].

My search shows “no results.” Does that guarantee my mark can be registered?

No. A blank result can mean several things: the mark falls within the six-month blind spot, the database has a 1–3 day update lag, your search terms were entered incorrectly, or — the best-case scenario — the mark genuinely has no prior claimant. Because of this ambiguity, a clean search result should be treated as a good sign, not a guarantee, and ideally followed by a professional registrability review before filing.

Can foreign companies or individuals use the official China trademark search system?

Yes. The China Trademark Website’s online query service is open to all users, including foreign companies and individuals, at no charge. The Unified Identity Authentication System also provides an English-language interface for overseas users completing registration^[4]. That said, keep two things in mind: China’s first-to-file principle differs fundamentally from the “first-to-use” approach common in countries like the United States, and the search interface itself is presented primarily in Chinese — which is why many foreign applicants engage a local agency to handle the process. See our guide on trademark registration in China for U.S. businesses for country-specific considerations.

What 2026 changes to Chinese trademark law should I know about before searching?

A draft amendment to the Trademark Law passed its first reading before the Standing Committee of the National People’s Congress in late 2025^[3]. The revision is expected to further strengthen the requirement that a registered mark reflect genuine intent to use it in business, building on Article 4’s existing bad-faith provisions. Since 2023, CNIPA has already rejected roughly 1.273 million applications and invalidated 3,351 registrations for bad-faith or non-use filings^[2]. Examination standards are expected to tighten further, which makes a thorough, professionally reviewed search more important than ever going into 2026 and beyond. Our trademark application trends report for overseas companies tracks how these shifts have played out for foreign filers.

Conclusion: Search First, File with Confidence

China’s trademark landscape now holds nearly 52 million active registrations, and roughly one in three new applications gets rejected^[1][2]. In that environment, filing without a proper search isn’t just risky — it’s close to guesswork. The official China Trademark Website gives you a strong, free starting point, and the new AI-powered “Search by Image” tool makes logo searches more accessible than ever. But every self-search — official or third-party — shares the same blind spots: a six-month visibility gap, data lag, and the fact that final similarity judgments are ultimately made by a human examiner, not an algorithm.

For businesses with real capital, timelines, and brand equity riding on a successful registration, pairing your own search with a professional registrability review is the difference between a smooth filing and months of delay. At Yucheng IP Law (YCIP), our team has guided foreign businesses through thousands of China trademark filings, combining official database access with the professional judgment a purely automated search cannot replicate.

Don’t file blind. Request a free trademark search and quote from our team, or contact YCIP directly to discuss your brand’s registrability before you submit a single application. You can also learn more about our full range of IP services, meet our team — including lead attorney Peter H. LI — or review our client track record and testimonials before reaching out.
