Key Takeaway

Before you invest in registering a trademark in China, you need to know if your brand name is already taken. CNIPA's database is free to search and publicly accessible — but it's entirely in Chinese. This guide walks you through how to search yourself, what to look for, and when to bring in a professional. A free search today can save you thousands in failed applications tomorrow.

Why Search Before Filing

The Cost of Not Searching

China's first-to-file system means the first applicant owns the mark. If you file without searching and the mark is already taken, your application will be rejected — and you lose the CNIPA filing fee (RMB 300 per class).

More importantly, a rejection reveals your brand interest to the existing mark holder, who may use this information strategically. And if you've already entered the Chinese market before discovering the conflict, the costs multiply.

What a Search Reveals

A trademark search tells you:

  • Exact matches: Is your exact brand name already registered?
  • Similar marks: Are there phonetically, visually, or conceptually similar marks?
  • Class conflicts: Is the mark registered in your target product class?
  • Pending applications: Is someone else trying to register the same name right now?
  • Filing trends: Are squatters actively targeting your brand or similar names?

How to Search CNIPA's Database

Step 1: Access the Database

The official CNIPA trademark database is available at sbj.cnipa.gov.cn (China National Intellectual Property Administration). Look for the trademark search function (商标查询).

Step 2: Search in Chinese

The database primarily accepts Chinese input. You'll need:

  • Your brand name in Chinese characters (if you have one)
  • Your brand name in pinyin (romanized Chinese)
  • Your brand name in English

Pro tip: Search all three versions. A mark that doesn't conflict in English may conflict in Chinese, and vice versa. This is especially important given the importance of Chinese names.

Step 3: Select the Right Classes

China uses the Nice Classification system with 45 trademark classes. Search in:

  • Your primary product/service class
  • Adjacent classes where confusion is likely
  • Classes where squatters commonly target your industry

Step 4: Review the Results

For each result, check:

  • Status: Is it registered, pending, or expired?
  • Owner: Who filed it? Is it a known squatter?
  • Class: Does it conflict with your target class?
  • Date: When was it filed? Is it within the 5-year challenge window?
  • Goods/services: Are the specific items similar to yours?

Step 5: Evaluate Similar Marks

Don't just look for exact matches. China's trademark law also prohibits marks that are:

  • Phonetically similar: Sound alike when spoken
  • Visually similar: Look alike in writing
  • Conceptually similar: Carry similar meanings

This is where professional search becomes valuable — automated searches often miss conceptual similarities that a human expert would catch.

What Free Search Can't Do

  1. Comprehensive similarity analysis. The database shows exact matches but doesn't analyze phonetic, visual, or conceptual similarity for you.
  1. Cross-class conflicts. Squatters often register in adjacent classes. You need to know which classes to search beyond your primary class.
  1. Pending application alerts. The database is a snapshot, not a monitoring tool. New filings that conflict with your brand won't trigger any notification.
  1. Legal interpretation. Knowing a mark exists is different from knowing whether it blocks your application. An experienced agent can assess the real-world impact.
  1. Chinese language nuance. If your brand has a Chinese name, understanding whether it's distinctive, descriptive, or potentially offensive requires native-level expertise.

When to Use Professional Search

Consider professional search when:

  • You're serious about entering the Chinese market
  • Your brand name is generic or descriptive (higher conflict risk)
  • You operate in a crowded industry (fashion, tech, food)
  • You need results within 24-48 hours
  • You want monitoring, not just a one-time check

What to Do After Searching

Scenario 1: No Conflicts Found

Great — but don't celebrate yet. "No exact matches" doesn't mean "safe to file." Consider:

  • Are there similar marks that could cause confusion?
  • Is your mark distinctive enough to pass CNIPA examination?
  • Have you searched all relevant classes?

Recommendation: File immediately. In China's first-to-file system, every day you wait is a risk.

Scenario 2: Conflicts Found

Don't panic. Options include:

  • Modify your Chinese name to avoid the conflict
  • File in different classes where the conflict doesn't exist
  • Challenge the existing mark if it was filed in bad faith (within 5 years)
  • Negotiate with the existing mark holder

See our guide on what to do when someone has your trademark for detailed recovery strategies.

Scenario 3: Similar but Not Identical Marks

This is the most common and most complex scenario. Similar marks may or may not block your application depending on:

  • How similar they are (phonetic, visual, conceptual)
  • Whether they're in the same or related classes
  • Whether the existing mark holder would likely oppose
  • CNIPA examiner's assessment of confusion likelihood

This is where professional guidance is most valuable.
