During CNIPA's 3-month publication window, file an opposition to block a conflicting trademark before it registers. Act fast — this window closes permanently.
File an OppositionCNIPA recognizes several valid grounds for opposing a trademark application.
You hold an earlier registration or well-known mark that is identical or confusingly similar to the published application.
The applicant filed with no intent to use, or preemptively registered your brand name knowing your reputation. Common with trademark squatters.
The mark misleads about the origin of goods, violating China's geographical indication protections.
The mark is generic, descriptive, or lacks distinctiveness and should not be registered by any party.
The mark is deceptive, contrary to socialist morality, or detrimental to public interest per Trademark Law Article 10.
The applicant is or was your agent or representative and filed your mark without authorization, violating Article 15.
The opposition process in China typically takes 12-18 months from filing to final decision.
Collect proof of prior use, registration certificates, brand reputation evidence, and market presence documentation.
Submit formal opposition with CNIPA within the 3-month publication period. Late filings are not accepted.

CNIPA issues a final ruling. Either party may appeal to the Beijing IP Court within 30 days of the decision.
