China Trademark Opposition: How to Block Squatters

28 7 月, 2026 | By ctms

Trademark opposition is a powerful tool to prevent bad-faith filings from being registered. In China, any interested party can oppose a published trademark within the 3-month opposition period.

Grounds for Opposition

  • Conflict with prior registered trademarks
  • Infringement of prior rights (copyright, trade name, design rights)
  • Bad-faith filing of a well-known mark
  • Unauthorized filing by agents or representatives

Opposition Procedure

1. Identify conflicting applications during the publication period
2. Prepare and file opposition with CNIPA
3. CNIPA notifies the applicant, who may respond within 30 days
4. CNIPA issues a decision (typically 6-12 months)
5. Dissatisfied parties may appeal to the court

Monitoring is Key

The 3-month publication window requires active monitoring. Our monitoring service alerts you within 48 hours of conflicting publications.
