Before You File in China: What a Trademark Clearance Search Covers and What It Misses
Most refused trademark applications in China could have been predicted. A clearance search before filing tells you whether an earlier mark is likely to block yours, but it has blind spots that foreign applicants often do not know about. This guide explains what a search in China covers, what it misses, and what to do with the result.
What the search covers
A clearance search looks for earlier applications and registrations in the CNIPA database that are identical or similar to your mark, in the same or similar goods. In China "similar goods" is decided largely by sub-class, so a proper search is run sub-class by sub-class, not just class by class. Similarity is assessed on appearance, pronunciation and meaning, which in China means checking the Latin mark, its likely Chinese transliterations and its Chinese translation.
Three tiers of search
- Knock-out search: identical marks in the target sub-classes. Fast and cheap; finds the obvious blocks.
- Full search: similar word marks, Chinese-character variants and figurative elements, with a written risk opinion. This is the level worth paying for before a launch.
- Watch: after filing, a periodic check of new publications so that conflicting applications can be opposed within the 3-month window.
What a search can miss
- Recent filings: new applications appear in the public database only after a delay, typically a few weeks. A clean search is a snapshot, so file soon after it.
- Figurative marks: logos are searched by figurative element codes, which is less precise than word searching. A logo with a distinctive word element should be searched both ways.
- Unregistered rights: earlier unregistered marks with a certain influence, well-known marks, company names, copyright in a logo and names of famous people can all be used to oppose or invalidate a registration, yet none of them sits in the trademark register.
- Bad-faith squatters: if your brand already has visibility in China, assume someone may file it once you start trading, and file before you announce.
Reading the result
A conflicting earlier mark does not always mean giving up. Options include narrowing the specification to sub-classes outside the conflict, adapting the mark, checking whether the earlier mark has been unused for three years and can be cancelled, or approaching the owner for an assignment or consent. Each has a different cost and timeline, and the choice should be made before filing rather than after a refusal.
Practical checklist
- Decide the Chinese-character version of the brand before searching, and search it too.
- List the sub-classes that matter to the business, not only the main class.
- Search word and logo separately.
- File within days of a clean search.
- Set up a watch once the application is filed.
