China is a prime market, and a prime target for trademark squatters. The good news is that the China National Intellectual Property Administration (CNIPA) has sharpened its tools against bad-faith filings. The work for brand owners is to detect the problem early and put the right evidence in front of CNIPA at the right time.
This guide explains how to spot bad-faith activity, how to oppose during publication, how to invalidate after registration, and how to use CNIPA's penalties and its own-initiative powers.
What Counts as Bad Faith in China
Four provisions of the Trademark Law carry most of the weight:
- Article 4: CNIPA must reject an application filed in bad faith with no intent to use.
- Article 33: any interested party can oppose a published application on bad-faith grounds during the opposition period, including on the basis of Article 4.
- Article 44: CNIPA, or any party, can seek invalidation of a registered trademark that was filed in bad faith.
- Article 19: trademark agents must not represent applications they know, or should know, are made in bad faith.
Those four anchor almost every practical strategy. Article 33 stops a trademark before it registers. Article 44 unwinds one that slipped through. Article 19 gives you leverage over the agencies that enable serial filers.
A revised Trademark Law was adopted on 26 June 2026 and takes effect on 1 January 2027. It shortens the opposition window from three months to two, lets CNIPA cancel an unused trademark on its own initiative, and raises the fines for agencies. The article numbers in this guide are those of the law in force until 31 December 2026, so ask our experienced attorneys which text applies to your matter.
CNIPA's examination guidance also addresses misuse in the market, including deceptive use of the registration symbol and agencies that assist bad-faith filings. The direction of travel is consistent: more proactive review, broader grounds to reject, and harsher consequences for filers and facilitators alike.
Detecting Bad-Faith Filings Early
Early detection saves money. Once a squatter's trademark registers, the effort to unwind it goes up and your settlement leverage goes down. Build a watch program that matches how squatters behave in China.
A Monitoring Workflow That Works
- Search the CNIPA database weekly for exact matches, phonetic equivalents, Chinese-character transliterations, and common misspellings, across your core and adjacent classes. Trademark monitoring automates that sweep.
- Track filer names across filings. Mass filers use multiple shells, so normalize by address and by agent to connect them.
- Monitor marketplaces (Tmall, JD, Pinduoduo), cross-border platforms, and customs detentions for signs of use or offers for sale.
- Set alerts for your brand in English and in Chinese. Lock in a consistent Chinese name early, because that shrinks the attack surface.
Red Flags
- Large portfolios disconnected from any genuine business: dozens or hundreds of trademarks across unrelated goods and services.
- Pre-emptive filings for your brand, or close variants, right after a product launch, a trade fair, or a PR push.
- Offers to sell the trademark, or extortionate licensing proposals, soon after filing.
- Copying of logos or trade dress, sometimes spread across several classes to force a settlement.
The Evidence Package to Assemble Now
Bad-faith claims depend on proof. Collect and curate:
- Prior use and reputation: dated marketing materials, press coverage, awards, sales data, channel listings, timestamped screenshots, trade fair brochures.
- The filer's awareness of you: emails, distributor negotiations, NDAs, WeChat threads, RFPs, or supplier conversations showing they knew your brand.
- Lack of intent to use: no products, no listings, no operations, a mass-filing pattern, prior sales of trademarks, or known squatter behavior.
- Agent knowledge: repeat representations by the same agency for famous trademarks, or evidence that an agent facilitated filings it should have flagged, which is what Article 19 addresses.
CNIPA examiners can and do reject on their own initiative under Article 4 where the record shows no intent to use or a mass-filing pattern. Your evidence can prime that result at examination, at opposition, or at invalidation.
Opposing During Publication (Article 33)
When and Why to Oppose
Opposition is the fastest way to block a bad-faith application before it hardens into a registration. During the publication period, any interested party can oppose on Article 4 grounds and others. Oppose where the filer is a known squatter, where your brand is already in use in China, or where your evidence of their awareness is strong.
What to File
- Grounds: cite Article 4 (bad faith, no intent to use) and any conflict with your prior rights. Address well-known mark considerations if they apply.
- Proof: attach the evidence above, organized, translated, and paginated. Avoid a data dump. Tie each exhibit to a specific assertion.
- Agency issues: where the filer's agent knew or should have known, flag Article 19 and ask CNIPA to refer the matter for administrative action.
What to Expect
CNIPA can reject the application, allow it, or ask for clarification. Where an earlier blocking trademark is itself under attack, related proceedings can be suspended pending the outcome of a non-use or invalidation action, which lets you sequence several tools to break a squatter's leverage.
After Registration: Invalidation and Non-Use Cancellation
Invalidation Under Article 44
If the bad-faith trademark registers, target it for invalidation on Article 4 grounds through Article 44. The same evidence applies: no genuine intent to use, awareness of your brand, or mass-filing behavior inconsistent with an operating business.
Non-Use Cancellation After Three Years
Non-use cancellation stays essential. After three consecutive years of non-use, you can petition to cancel. Combining a bad-faith narrative with non-use proof strengthens the outcome and discourages tactical refiling.
Cancellation on CNIPA's Own Initiative
Where the abuse is wide enough to affect market order, ask CNIPA to use its own powers to order rectification or cancel unused or misleading trademarks. Failing to comply with a rectification order carries its own consequences.
Recovering Enforcement Costs
Where you can prove loss, keep a clean record of what stopping the infringement cost you. Administrative routes are faster, but documenting the spend preserves your options for recovery later.
Penalties and Deterrence
Chinese law penalizes both the bad-faith filer and the agency that helps them. Fines apply to agencies for illegal conduct in facilitating bad-faith trademarks or deceptive signs, and the revised law in force from 1 January 2027 raises the ceiling to ¥200,000 in serious cases. Where you uncover agency misconduct, file a report alongside your opposition or invalidation. That is what changes the economics for a serial filer.
Do not misuse the registration symbol. CNIPA's guidance singles out deceptive use of the registration symbol on unregistered trademarks. Misuse can attract a fine even where the underlying application is later refused. Train your marketing teams and your distributors on when the symbol can be used in China.
Common Pitfalls
- Missing the publication window. If you do not oppose during publication, you are into post-registration invalidation, which is slower and costlier.
- Thin evidence. Assertions without proof rarely carry. Curate exhibits that speak to awareness, to lack of intent to use, and to your prior presence.
- Over-defensive filing. Filing far beyond your needs invites scrutiny in its own right. Map classes to genuine or planned use.
- Ignoring administrative routes. Litigation alone is slow. CNIPA procedures deliver rejections, suspensions, and cancellations faster in most scenarios.
- Agent blind spots. Under Article 19, agents cannot look the other way. Work with compliant counsel and report the outliers.
- Careless use of the registration symbol, which attracts penalties even when it was inadvertent.
Three Playbooks You Can Use Tomorrow
Scenario 1: A Competitor Files Your Brand in Your Core Class
- Week 0: your watch flags a published application matching your brand.
- Action: prepare an opposition citing Articles 33 and 4, attach evidence of prior use and of the filer's knowledge, and raise agency liability where relevant.
- Follow-on: if the opposition fails, file for invalidation under Article 44, with non-use cancellation as the backstop once it becomes available.
Scenario 2: A Serial Squatter Blankets Your Brand Across Classes
- Week 0: monitoring shows multiple filings by the same filer across unrelated goods and services.
- Action: oppose each one during publication, and in parallel compile a dossier documenting the mass-filing pattern and the absence of any genuine business.
- Follow-on: seek coordinated handling where possible, and request administrative penalties against the agency.
Scenario 3: A Dormant Registration Blocks Your Launch
- Discovery: a trademark identical or close to yours registered years ago, with no sign of genuine use.
- Action: file a non-use cancellation after three years of inactivity, and if the facts support it, an invalidation for bad faith as well.
- Follow-on: ask CNIPA to suspend any related proceedings pending those outcomes.

Cost Planning
CNIPA's government fee is about ¥270 per class for an online application covering up to ten items of goods or services, and an opposition costs ¥450 per class when filed online (¥500 on paper). Translation and evidence preparation are usually the larger line in a contested matter, so budget for them separately. For the Total for filing or defending in China, see our China trademark service, and the China country guide for how the system fits together.
Two planning points:
- Defensive filings shrink the attack surface and cost far less than an opposition. File where you sell or plan to sell, and keep the class list tied to genuine business needs.
- An international application through WIPO's Madrid System (the Madrid Protocol) is efficient for a wide rollout, but include China early, and remember that it does not insulate you from a China-specific bad-faith challenge.
Evidence Checklist
Use this as a working list to assemble a file that persuades CNIPA:
- Your brand use timeline in China and abroad: dates, channels, sales volumes, media coverage.
- Proof the filer knew your brand: emails, distributor discussions, WeChat messages, trade fair contacts, shared suppliers.
- Proof of no intent to use: no operations, no listings, a mass-filing history, prior attempts to sell trademarks.
- Connections among shell filers: shared addresses, agents, contact details.
- Your Chinese name strategy, the chosen transliteration or translation, and evidence of its use.
- Any misuse of the registration symbol or other deceptive conduct by the filer in China.
- A request for agency penalties where the facts support one.
What Winning Looks Like
- At examination: the examiner rejects a mass-filing application for lack of intent to use under Article 4, and you never have to oppose.
- During publication: your opposition succeeds under Article 33, citing Article 4 and clear evidence of awareness and of no intent to use.
- After registration: you invalidate under Article 44, or cancel for non-use after three years, or both.
- Deterrence: CNIPA warns or fines the agency behind the serial abuse, and the squatter backs off or accepts a narrow coexistence that leaves your core untouched.
Each of those outcomes gets more likely when your monitoring is tight, your filings match genuine use, and your evidence file is curated rather than bloated.
Key Takeaways
- Move during the publication window. Do not rely on post-registration fixes.
- Build an evidence file that proves awareness, lack of intent to use, and your prior rights.
- Use the administrative tools first: rejection, opposition, invalidation, non-use cancellation, and suspension.
- Press for penalties against serial abusers and the agencies that serve them, because that is what changes behavior.
- File defensively where you sell, and keep it within normal business needs.
