Your China Trademark Agent May Be Filing Against You

Your agent knows the brand name before your own staff do. They know the classes, the goods, the launch date, and the markets. That is an informational advantage no outside squatter can match, and the law contains two specific provisions because some agents have used it.

The pattern is quiet. A brand asks an agency to check availability. The agency comes back with a report: the name is clear in two classes, blocked in a third, and here is a slightly different name that is available across all three.

The brand picks the alternative. Months later, someone searches the original name and finds it registered, filed a few weeks after that availability report, in the name of an entity with no obvious connection to the brand.

Sometimes the entity has no connection at all. Sometimes it is the agency's own filing arm.

Quick answer: Article 15 of the Trademark Law provides that where an agent or representative registers the principal's mark in its own name without authorization, the mark shall not be registered and its use shall be prohibited. Article 19(4) separately bars trademark agencies from filing marks other than for their own agency services, with a fine of CNY 10,000 to CNY 100,000 for breach. Both provisions exist because the conduct is common enough to need them, and both are only usable if you can see the register record.

The information problem, stated plainly

To file your mark, an agent needs your name, your logo files, your class list, your goods specification, and your priority date. To file against you, an agent needs exactly the same set of facts.

There is no asymmetry. The agent is not guessing. They have the specification you approved, and they know which classes you decided were too expensive.

That last point is the sharpest edge. Every brand makes a cost decision about how many classes to file. The agency sees the decision, sees the reasoning, and sees the gap that was left. A filing in the class the client declined is cheap, plausible, and positioned precisely where the client will need it in three years.

Article 15: the agency provision

Article 15 addresses exactly this relationship. Where an agent or representative files, in its own name and without the principal's authorization, a mark belonging to the principal, the mark shall not be registered, and where registered, its use shall be prohibited.

Two features make it strong.

It reaches registration, not just filing. The provision applies at examination and continues to apply after grant, which means it is available as an invalidation ground rather than only as an opposition ground.

It does not require proof of bad faith in the abstract. The relationship itself is the operative fact. Once agency is established and the mark is shown to belong to the principal, the analysis is largely mechanical.

The evidentiary load sits in two places: proving the agency relationship, and proving the mark belonged to the principal at the time of filing. The first is usually a contract or a chain of correspondence. The second is usually the brand's own materials predating the filing, which is why dated files matter more than polished ones.

Where the relationship is thin, the fallback is Article 44 improper means, which carries a heavier burden because it asks the decision maker to find that the registration was obtained by improper means rather than simply that an agent acted outside its mandate. The framework is in the bad-faith registration defense guide.

Article 19(4): the rule aimed at agencies as a class

Article 19(4) is narrower in scope and broader in effect. A trademark agency may not, beyond the marks it files for its own agency services, apply for trademark registration.

The purpose is structural. An agency that can hold marks has a conflict of interest in every availability opinion it gives. The provision removes the ability rather than policing the motive.

Breach carries an order to correct, a warning, and a fine of CNY 10,000 to CNY 100,000, roughly USD 1,500 to USD 15,000 at the October 2026 mid-rate. The fine is modest relative to the value of a blocking registration, which is why the provision is more useful as an invalidation argument than as a deterrent.

The fourth row is worth pausing on. Many agent-filed blocking marks are never used, because the point was never to trade under them. That makes them vulnerable to a non-use cancellation for CNY 450, about USD 67, which is often faster and cheaper than arguing Article 15. The procedure is in the non-use cancellation guide.

How to check whether this is happening to you

The check is short and it is the same check regardless of how the relationship ended.

1. Search the mark, all classes. Not the classes you filed. All of them. The filing you did not make is the one to look for.
2. Read the applicant name on any conflicting filing. Not the agent of record. The applicant. Then search that applicant name across the register.
3. Search the agency's legal entity name on the register. A legitimate agency files almost nothing in its own name. An agency with dozens of filings across unrelated classes is telling you something.
4. Compare filing dates to your correspondence. A filing dated within weeks of an availability report is the pattern that matters, and it is visible from dates alone.
5. Check the address. Filing addresses are published. An applicant address matching the agency's office is not conclusive, but it is a lead.
6. Confirm the agency is on the CNIPA filing register. Unregistered agencies cannot lawfully act, and the register is public.

Steps one through three take a single session. Step four requires you to still have the correspondence, which is why the practical advice is to keep it. The search method itself is in the CNIPA search guide.

What to do before you need any of this

Four practices, none of them exotic.

File before you ask for an opinion. An availability search is useful, but the filing is what protects you. Where the brand matters, file first and search in parallel, so that the search result cannot become someone else's filing.

Do not hand over the full class strategy. An agent needs the classes you are filing. They do not need the classes you considered and rejected. Share the instruction, not the deliberation.

Keep dated records of your own use. Packaging, listings, invoices, advertising. The Article 15 argument depends on showing the mark belonged to you before the filing, and undated design files do not show that.

Monitor the applicant entities, not just the mark. Monitoring the mark catches a conflicting filing. Monitoring the entities that have already filed against you catches the next one. The mechanics are in monitoring for squatters.

One honest caveat: most Chinese trademark agencies are compliant, and the overwhelming majority of filings are exactly what they appear to be. The provisions exist for the minority, and the point of this article is not suspicion of every agent. It is that the register is public, the check is cheap, and the information asymmetry runs the wrong way by default.

Questions that come up every time

Can my China trademark agent register my brand?

Article 15 prohibits it where an agency relationship exists and the mark belongs to the principal, and provides that such a mark shall not be registered and its use prohibited. Article 19(4) separately bars agencies from filing marks outside their own agency services.

What if my agent told me my mark was unavailable and it was not?

Search the register yourself and read the applicant name and address on the blocking application. If it traces to the agency or an affiliate, Article 15 or Article 19(4) may apply, and the register record is the evidence.

How do I check whether an agency is legitimate?

Confirm it appears on the CNIPA register of trademark agencies, confirm the contracting legal entity matches, and search that entity name on the trademark register to see what it has filed in its own name.

What penalty applies to an agency that files a client's mark?

Article 19(4) provides for an order to correct, a warning, and a fine of CNY 10,000 to CNY 100,000. The registration can be refused or invalidated under Article 15 or Article 44.

Can I switch agents mid-application?

Yes. A change requires a power of attorney and a recordal with CNIPA. The application number and filing date are unaffected, so priority is preserved.

How would I know my agent filed against me?

Only by searching. There is no notification to the brand. Monitoring the mark text and the applicant entity name is the only way the filing surfaces before it becomes a blocking registration.

Is it worth pursuing an agency legally?

Usually the objective is the registration, not the fine. Invalidation or cancellation removes the block; a regulatory complaint is a secondary lever and rarely the fastest one.

Does this risk exist with foreign agencies too?

The provisions are Chinese and apply to Chinese practice, but the information asymmetry exists in any jurisdiction. What differs is the remedy available, and in China the remedy is unusually specific.
