China Trademark Opposition: Challenging or Defending a Mark Before CNIPA

China Trademark Opposition: Challenging or Defending a Mark Before CNIPA

After a trademark application passes CNIPA's substantive examination, it is published in the Trademark Gazette for a 3-month opposition period. During this window, any interested party can file an opposition to prevent the mark from proceeding to registration.

Opposition proceedings are a critical enforcement tool in China — particularly for combating trademark squatting in this first-to-file jurisdiction.

Pro tip: Monitor published marks that could conflict with yours. Start with a free trademark check to understand your brand's exposure in China.

The Opposition Period

Timeline

Who Can File an Opposition?

Under the 2019 amendment to the Trademark Law, any interested party (在先权利人或利害关系人) can file an opposition. This includes:

• Owners of prior trademark registrations or applications
• Owners of prior rights (copyright, trade name, design patent)
• Parties with evidence of bad faith filing
• Authorized agents or representatives whose marks were filed without consent

Grounds for Opposition

Relative Grounds

Article 30/31 — Conflict with Prior Marks:

The opposed mark is identical or similar to the opponent's prior registered or pending mark for identical or similar goods/services. This is assessed within CNIPA's sub-class system.

Article 13 — Well-Known Mark Protection:

The opposed mark copies, imitates, or translates a well-known mark, and registration would mislead the public or damage the well-known mark owner's interests.

Article 15 — Agent/Representative Bad Faith:

The applicant is (or was) the opponent's agent or representative and filed the mark without authorization.

Article 32 — Prior Rights and Prior Use:

The opposed mark:

• Infringes the opponent's prior rights (copyright, trade name, etc.)
• Was filed in bad faith to register a mark that the opponent has already used and gained certain influence

Absolute Grounds

Article 10 — Prohibited Marks:

The mark falls within prohibited categories (national symbols, deceptive marks, marks against public interest).

Article 11 — Lack of Distinctiveness:

The mark is generic, descriptive, or otherwise lacks distinctiveness.

Article 4 — Bad Faith Filing (2019 Amendment):

The application was filed in bad faith without intent to use — a powerful new tool against trademark squatters who file hundreds of marks with no genuine business purpose.

Filing an Opposition

Required Documents

Evidence Requirements

Strong opposition cases require robust evidence:

For Prior Mark Conflicts:

• Prior trademark registration certificates
• Evidence of use and reputation in China
• Sales data, advertising spend, market presence
• Consumer surveys (if available)

For Bad Faith/Squatting:

• Evidence the applicant knew of the opponent's mark
• Business relationship between the parties
• Pattern of squatting behavior (applicant filing many unrelated marks)
• Evidence of the opponent's prior use and reputation

For Prior Rights (Copyright, Trade Name):

• Copyright registration certificates
• Creation dates and authorship evidence
• Business registration showing trade name
• Evidence of prior use and public recognition

CNIPA Opposition Decision

CNIPA will examine the opposition and issue a decision within 12 months (extendable to 18 months in complex cases).

Possible Outcomes

Important 2014 Amendment Change

Since the 2014 amendment, if CNIPA rejects the opposition (i.e., allows the mark to register), the opponent cannot appeal directly. Instead:

• The mark proceeds to registration
• The opponent must then file an invalidation request with TRAB
• This changed the dynamic significantly — opposition rejection is no longer the end

If CNIPA upholds the opposition (refuses the mark), the applicant can request TRAB review within 15 days.

TRAB Review of Opposition Decisions

The losing party in an opposition proceeding can seek TRAB review:

For the Applicant (Opposition Upheld)

• File review request within 15 days of the opposition decision
• TRAB reviews de novo — considers new evidence and arguments
• Decision within 12 months (extendable to 18 months)

For the Opponent (Opposition Rejected)

• Cannot directly appeal the opposition rejection
• Must wait for registration, then file an invalidation request with TRAB
• Invalidation can be filed within 5 years of registration (no time limit for well-known marks or bad faith)

Anti-Squatting Strategies

China's first-to-file system creates significant squatting risks. Effective anti-squatting strategies include:

Proactive Measures

1. File early and broadly — register your mark before entering the Chinese market
2. Register Chinese character versions — file transliterations, translations, and hybrid versions
3. Cover key sub-classes — don't leave gaps in your sub-class coverage
4. Monitor the Trademark Gazette — watch for conflicting applications during the 3-month window
5. Use trademark monitoring services — automated alerts for similar filings

Reactive Measures

1. Opposition during publication — the most cost-effective time to challenge
2. Invalidation after registration — within 5 years (unlimited for bad faith/well-known marks)
3. Non-use cancellation — after 3 years of non-use by the registrant
4. Article 4 bad faith — challenge marks filed without genuine intent to use (2019 amendment)
5. Customs recordation — register with Chinese customs to intercept infringing goods

Defending Against an Opposition

If your trademark application faces opposition, you have the right to file a defense (答辩):

Defense Strategy

• Respond within the deadline — typically 30 days from receiving the opposition notice
• Address each ground — respond to every argument raised by the opponent
• Provide evidence of legitimate use — show genuine business activity and intent
• Distinguish your mark — demonstrate visual, phonetic, and conceptual differences
• Challenge the opponent's standing — if they lack the required interest or prior rights

Common Defense Arguments

• Marks are sufficiently different to coexist
• Goods/services are in different sub-classes or trade channels
• Applicant has independent prior use and reputation
• Opponent's mark lacks distinctiveness or fame
• Opposition is filed for improper purposes (harassment, delay)
