Trademark Opposition in China: How to Protect Your Brand Rights

The Opposition Window: 3 Months to Act

Once CNIPA approves a trademark application, it is published in the Trademark Gazette. For the next 3 months, any interested party can file an opposition. This is a critical window — once it closes and the mark is registered, removing it becomes much harder and more expensive.

Filing an Opposition: Step by Step

  1. Monitor the Gazette: Regularly check the Trademark Gazette or use a monitoring service. CNIPA publishes weekly.
  2. Gather evidence: This is the most important step. Collect proof of your prior rights (registration certificates), evidence of use in China (sales, advertising, media coverage), and documentation of the applicant's bad faith (if applicable).
  3. Prepare the opposition brief: A detailed legal argument addressing each ground, supported by evidence.
  4. Submit to CNIPA: File within the 3-month window. Late filings are rejected.
  5. Wait for CNIPA decision: CNIPA typically decides within 12 months.
  6. Evidence That Works

    • Prior trademark registration certificates (Chinese or foreign)
    • Notarized evidence of use: sales contracts, invoices, shipping documents
    • Advertising materials, brochures, catalogues
    • Media coverage, industry awards, rankings
    • Consumer survey data (professionally conducted)
    • Evidence of the applicant's bad faith (pattern of squatting, demand letters)

    After the Decision

    If you win, the opposed mark is rejected. If you lose, you can appeal to TRAB within 30 days. An unsuccessful opposition does not prevent you from filing subsequent invalidation proceedings.
