Searching for trademark images and logos in China’s CNIPA database is fundamentally different from word mark searches. Device marks — including logos, figurative elements, and combined marks — require a specialized approach that many foreign applicants overlook. This guide explains how to conduct effective image-based trademark searches in China.
Understanding Device Marks in China
In Chinese trademark law, device marks are classified under the Vienna Classification system, an international standard for categorizing figurative elements of trademarks. CNIPA uses this system to index and search logo elements across all 45 Nice classes.
Key facts about device marks in China:
- Separate Registration: A logo with text is typically registered as a “combined mark.” The word elements and device elements are protected together, not separately.
- Color Claims: If you file in black and white, your mark is protected in all colors. If you claim specific colors, protection is limited to those colors.
- Strict Examination: CNIPA examiners compare device marks using the Vienna Classification codes, visual similarity, and overall commercial impression.
Step-by-Step: CNIPA Image Search
Step 1: Access the CNIPA Image Search Interface
Navigate to sbj.cnipa.gov.cn and select the Figure Search option. This is different from the text search interface and requires a different approach.
Step 2: Identify Vienna Classification Codes
Before searching, you need to identify the Vienna Classification codes that describe your logo elements. The Vienna system categorizes figurative elements into 29 broad categories, each with subcategories. For example:
- Category 1: Celestial bodies, natural phenomena, geographical maps
- Category 2: Human beings
- Category 3: Animals
- Category 5: Plants
- Category 26: Geometrical figures and solids
- Category 27: Forms of writing, numerals
You can browse the full Vienna Classification on the WIPO website or use the CNIPA’s built-in code browser.
Step 3: Enter Vienna Codes and Search
Enter the Vienna codes that correspond to your logo elements. For example, a logo featuring a stylized eagle would use codes from Category 3 (Animals) + Category 3.7 (Birds). You can combine multiple codes to narrow the search.
Step 4: Refine by Class and Status
After entering the Vienna codes, add additional filters:
- International Class: Limit to the classes relevant to your goods/services
- Application Date: Focus on recent filings or a specific time period
- Status: Filter for active registrations only
Alternative: Visual Similarity Search
CNIPA has introduced an AI-powered visual similarity search feature. You can upload an image of your logo, and the system identifies visually similar registered marks. This is particularly useful for:
- Complex logos with multiple figurative elements
- Marks where Vienna Classification alone is insufficient
- Quick preliminary screening before a detailed search
Limitation: The AI search is a helpful tool but should not replace a comprehensive professional search. It may miss conceptually similar marks that use different visual elements.
Common Pitfalls in Image Search
Pitfall 1: Relying Only on Vienna Codes
Vienna Classification is a starting point, not a complete solution. Two logos with the same Vienna codes can be visually very different. Conversely, two logos with different codes can be confusingly similar. Always review the actual images in the search results.
Pitfall 2: Ignoring Stylized Text
In China, stylized text is treated as a device element. A logo that consists primarily of stylized Chinese characters or English letters may be classified under Vienna Category 27 (Forms of writing) rather than as a word mark. Search both ways.
Pitfall 3: Overlooking Color Variations
If your search target is in black and white, it could conflict with a registered mark in specific colors — and vice versa. CNIPA considers the overall commercial impression, not just the registration format.
