## Trademark Similarity Search in China Before Filing: A Practical Guide For foreign brand owners planning to enter the Chinese market, conducting a similarity search before filing a trademark application is both the most critical and the most easily overlooked step. China follows a "first-to-file" principle — whoever files first owns the trademark rights, regardless of whether the mark has been used in the marketplace. This means that if your mark is deemed similar to a prior-filed trademark, CNIPA will directly reject your application, and any official fees and agency costs already paid will not be refunded. This article provides a systematic overview of the rules, operational methods, and risk mitigation strategies for conducting trademark similarity searches in China. ## I. Core Rules for Determining Trademark Similarity in China During substantive examination, CNIPA applies the "Trademark Examination and Adjudication Guidelines," under which the determination of "similar trademarks" follows the core logic outlined below. ### 1.1 Basic Definition of Similarity Trademark similarity means that two marks are similar in terms of the shape, pronunciation, or meaning of their characters, or the composition, coloring, or appearance of their designs, or in the overall structure of combined text and design elements, when used on identical or similar goods/services, such that the relevant public may be confused as to the source of the goods or services. China's examination of similar trademarks is extremely strict — far more so than in many common law countries. Even if two marks are visually quite different, they may still be rejected if their pronunciation or meaning is similar. ### 1.2 The Three Elements of Examination When examining similarity, CNIPA considers three dimensions simultaneously: | Examination Dimension | Standard of Assessment | Common Example | |----------|----------|----------| | Similarity of the mark itself | Degree of similarity in shape, pronunciation, meaning, and overall appearance | "Starbucks" (星巴克) vs. "Xingbake" (星巴客) — similar pronunciation, deemed similar | | Similarity of goods/services | Whether they fall within the same similar group | In Class 25, "clothing" and "shoes" belong to different similar groups and are not considered similar goods | | Likelihood of confusion | Whether the relevant public, applying ordinary attention, would likely be misled | Well-known marks enjoy cross-class protection under different standards, which is beyond the scope of this article | It is important to note that China uses the "Classification of Similar Goods and Services" (based on the Nice Classification but with certain adjustments), which divides goods and services into 45 classes, with each class further subdivided into "similar groups." Two marks can only be deemed similar if they are used on **identical or similar goods/services**. A common misconception is that filing in one class provides protection for all goods within that class. In fact, CNIPA examines on a per-similar-group basis, and goods in different similar groups within the same class may not be considered similar goods. ## II. How to Conduct a Pre-Filing Trademark Search ### 2.1 CNIPA Official Search System CNIPA's subordinate China Trademark Office website provides a free trademark search system, which is the most direct official data source. The search steps are outlined below: 1. Visit the China Trademark Office website and enter the "Trademark Search" section 2. Select "Comprehensive Trademark Search" or "Trademark Similarity Search" 3. Enter the trademark name to be searched (in Chinese, English, or pinyin) 4. Select the international class number to limit the search scope 5. Review the search results and analyze prior right obstacles The official system's data is updated weekly, with a data gap of approximately 1-3 weeks — applications that have been recently filed but not yet entered into the database cannot be retrieved. This means that even if your search results show no prior similar marks, there may still be "pending applications" that are not yet visible. ### 2.2 Practical Recommendations for Search Strategies Based on Chinese examination practice, the following multi-dimensional search strategy is recommended: - **Exact Match Search**: Search for the identical trademark name directly to identify any direct conflicts - **Phonetic Search**: Search for marks with similar pronunciation using pinyin or homophones. For example, when searching "Coca-Cola" (可口可乐), you should also search for variations such as "Keke Kele" (可可可乐) or "Kouke Kele" (口渴可乐) - **Character Shape Search**: In Chinese trademarks, characters with similar shapes (e.g., "日" vs. "曰", "已" vs. "巳") may be deemed similar - **Meaning Search**: Chinese translations of foreign trademarks may also constitute prior rights. For example, if you wish to register the Chinese translation of "Apple," you should first confirm whether "Pingguo" (苹果) has already been registered by another party - **Figurative Element Search**: For figurative/design marks, CNIPA uses the Vienna Classification system, and you may search using the corresponding figurative element codes ### 2.3 Whether to Engage a Professional Firm for Searching For foreign brands with only one or two trademark applications in China, using the CNIPA official free system for basic searching is a sufficient starting point. However, in the following situations, a deeper search through a professional firm (such as WeRights) is strongly recommended: - Planning to apply for a Chinese word mark (Chinese similarity standards are complex and difficult for non-native speakers to assess accurately) - Applications involving combined text and figurative element marks - Marks containing generic industry terms or descriptive words (examiners are more likely to reject on grounds of "lack of distinctiveness" or "similarity to prior trademarks") - A high volume of prior applications within the same class (requiring manual screening and item-by-item analysis) A professional search report typically includes: a list of prior conflicting trademarks, the registration status of each conflicting mark (valid/invalid/under opposition), a similarity rating (high/medium/low) between each conflicting mark and the applied mark, and specific recommendations for action. ## III. Avoiding Common Fatal Mistakes According to CNIPA refusal data, approximately 60% of formality examination refusals can be avoided through proper pre-filing searching. The following are the most common search and filing errors: 1. **Ignoring "Similar Group" Boundaries**: As discussed earlier, a single class does not equate to full protection across all goods within that class. Filing in Class 25 for "clothing" (similar group 2501) does not automatically cover "shoes" (similar group 2507). If you plan to use the same mark on goods across multiple similar groups, you must designate each group at the time of filing and search for obstacles in each group individually. 2. **Searching Only the Text, Ignoring the Design**: Many applicants, when filing combined text and design marks, search only for the text portion, overlooking the possibility that the design portion may be similar to a prior design mark. In CNIPA's overall examination of combined marks, if any element (text or design) is found similar to a prior mark, the entire application will be rejected. Recommended strategy: file the text and design elements separately to secure independent protection for each and reduce the overall risk of rejection. 3. **Overlooking Chinese Translations or Transliterations**: Foreign brands entering the Chinese market typically need a Chinese name. This Chinese name itself constitutes an independent trademark application and must be searched separately. A common real-world lesson: a foreign trademark may be successfully registered globally, but its corresponding Chinese transliteration may have already been squatted by another party in China. For example, a cosmetics brand from Europe or the Americas may discover upon entering China that its Chinese transliteration has already been registered by a Chinese company in Class 3 (cosmetics) — this scenario can only be resolved through opposition or invalidation procedures, which are time-consuming and costly. 4. **Not Considering the Customs Recordal Database**: Although trademarks recorded in the China Customs Intellectual Property Protection Recordal System overlap with the CNIPA trademark database, some enterprises have obtained factual rights based on prior use through customs recordal. It is recommended to also search the customs recordal database before filing a formal application. 5. **Ignoring the "Non-Use Cancellation" Risk**: A prior conflicting mark discovered during the search may be subject to cancellation for "non-use for three consecutive years" (i.e., the "non-use cancellation" procedure). For conflicting marks that have been registered for more than three years, if it is confirmed that they have never been used in the Chinese market, you may consider filing a cancellation action against them to clear the obstacle before submitting your own application. However, note that the non-use cancellation procedure requires 6-12 months and that a reasonable justification for the evidence search must be provided. ## IV. Decision Paths After the Search After completing the search and preliminary analysis, you will face several scenarios, each requiring a different strategy: ### Scenario One: No Prior Conflicting Marks This is the ideal scenario. It is recommended to file your trademark application as soon as possible. China is a first-to-file country — filing one day earlier gives you one day earlier priority. Note that you should not engage in large-scale use of the mark in the Chinese market before filing; if the application is later rejected, any marketing costs already incurred will be unrecoverable. ### Scenario Two: Highly Similar Prior Conflicting Marks Exist In this case, the status of each conflicting mark should be analyzed individually: - **Registered and in-use conflicting marks**: These pose the greatest risk. You should seriously consider changing the trademark name or adjusting the design to create a clear visual or phonetic distinction from the conflicting mark - **Registered but possibly unused for three consecutive years**: You may file a non-use cancellation action against this conflicting mark and submit your own application only after CNIPA issues a cancellation decision. This strategy is suitable when the conflicting mark has been registered for more than three years and investigation confirms it has not been used in the Chinese market - **Conflicting marks still under examination**: If the conflicting mark's filing date is earlier than your planned filing date, monitor its examination status. If it enters the publication period, you may consider filing an opposition during that period - **Conflicting marks that have lapsed**: No obstacle exists; proceed with a normal application ### Scenario Three: Obstacles Exist for Certain Goods/Services If obstacles exist only in certain similar groups, while the similar groups covering your core business are clear, you may adopt a "divisional application" strategy: file for the unobstructed portion as soon as possible, and separately assess the obstructed portion. ## V. Post-Filing Continuous Monitoring The search work does not end once the trademark application is filed. The Chinese trademark registration process includes a three-month publication period (preliminary approval announcement), during which any interested party may file an opposition. Therefore, continuous monitoring is recommended at the following stages: 1. **4-6 months after the filing date**: Monitor for the publication of the preliminary approval announcement, confirming whether your mark has passed substantive examination 2. **During the publication period**: Closely monitor whether any party files an opposition against your mark. If an opposition is filed, you must submit a defense within 30 days of receiving the notice 3. **After successful registration**: It is recommended to conduct market monitoring on a quarterly basis to check whether third parties have filed subsequent applications similar to your mark. For such subsequent applications, you may file oppositions during their publication periods to prevent market confusion 4. **At the three-year mark post-registration**: Assess the preservation of evidence of use. If your mark is actually used in the Chinese market, preserve evidence such as product packaging bearing the mark, sales contracts, invoices, and advertising materials, to prepare for potential non-use cancellation actions The average examination period for Chinese trademark registrations is approximately 4-7 months (from the filing date), plus the three-month publication period, meaning the entire process takes 7-10 months to complete successfully. Thorough preparation during the search phase can significantly reduce complications and additional costs during this period.
