Practical Answer — China Trademark Conflict

What should I do if a Chinese supplier registered my trademark?

By Peter Lin, Founder, China IP Gateway · July 2026

This page is informational guidance, not formal legal advice. It is intended to help you understand the situation and identify practical next steps.

In short

If a Chinese supplier, factory, distributor, sourcing agent, or other party has filed your brand in China, first confirm the CNIPA record, applicant name, filing date, class, subclass, and current stage. Then review the supplier relationship and evidence before deciding whether opposition, invalidation, non-use cancellation, parallel filing, negotiation, or supplier-control action is realistic.

First, confirm what actually happened

Before taking any other step, verify the official CNIPA record. An alert email or third-party notification may be inaccurate, incomplete, or commercially motivated. The CNIPA record is the only authoritative source.

Is there a real CNIPA record?

Is the mark pending, published, registered, opposed, or invalidated?

Who is the applicant — name, company type, location?

What class and subclass does it cover?

Does it cover the English mark, Chinese-character mark, logo, or similar wording?

Second, identify who filed it

The analysis differs depending on who the applicant is. The strategy, evidence requirements, and available path may vary significantly based on the applicant's identity and their prior relationship with your brand.

Your factory

Manufacturing relationship may be key evidence

A sourcing agent

Access to brand materials through sourcing role

A distributor

Commercial relationship creates disclosure exposure

A trading company

May have seen the brand through intermediary role

An unrelated squatter

Bad-faith focus without prior relationship

Former employee or partner

Relationship history and brand exposure matter

Third, preserve evidence before arguing

Do not confront the supplier or make demands before securing and organizing your evidence. Evidence that shows the supplier's prior exposure to the brand is often central to a bad-faith challenge or prior-relationship argument.

Supplier chats and emails referencing the brand

Alibaba messages and contact records

Quotes, invoices, and purchase orders

Packaging files shared with the supplier

Sample records and approval communications

Factory introductions with brand context

Trademark monitoring alerts with dates

Earlier foreign trademark registrations

Product launch, crowdfunding, Amazon, or Shopify evidence

Documents showing the supplier learned the brand from you

Fourth, check the procedural stage

If still pending or published — opposition may be time-sensitive

The opposition window in China is typically three months from the publication date. If the mark is published and the window is still open, opposition may still be available — but timing is critical. Acting early matters more than acting perfectly.

If already registered — invalidation or non-use cancellation may need review

Registration does not make a challenge impossible, but the procedure shifts. Invalidation on bad-faith grounds and non-use cancellation (after three or more years of documented non-use) are the main post-registration routes. Both require case-specific evidence review.

If the class or subclass is different — parallel filing may still help

A supplier-filed mark may not cover all classes or subclasses relevant to your products. If gaps exist, parallel filing in your own name may still be possible. This does not resolve the conflict, but it may limit the damage and establish a new priority date.

If Chinese-character marks are involved — check those separately

A supplier may have filed the Chinese-character transliteration of your brand separately. Chinese-character marks are treated as independent filings in China. Both the English mark and any Chinese-character versions should be checked in the CNIPA database.

Do not assume there is only one option

Depending on the stage, evidence, and facts, several routes may be available — and they are not always mutually exclusive. A case-level review is usually the right starting point before committing to any one path.

Opposition

Pre-registration, time-limited window

Invalidation

Post-registration, bad-faith grounds

Non-use cancellation

After 3+ years of documented non-use

Parallel filing

Fill class or subclass gaps in your own name

Negotiation / coexistence

Commercial resolution with the filing party

Customs recordal

After your own registration is secured

NNN / OEM agreement review

Contract layer for ongoing supplier relationship

Supplier-control review

Factory relationship, payment path, access control

What not to do

Do not rely only on screenshots without saving dates and URLs

Do not threaten the supplier before preserving evidence

Do not assume foreign trademark ownership automatically controls China

Do not file randomly in one class without subclass review

Do not ignore Chinese-character versions of the brand

Frequently Asked Questions

Can a Chinese supplier legally register my trademark in China?

China is generally a first-to-file trademark system, so a supplier-side filing can create a real problem even if the brand originated overseas. Whether the filing can be challenged depends on the facts, evidence, filing stage, class, subclass, bad-faith indicators, and the relationship between the supplier and the brand owner.

What is the first thing I should check?

Check the CNIPA record. Confirm the applicant name, filing date, class, subclass, mark image or wording, and current status. The available options depend heavily on whether the mark is still pending, published for opposition, already registered, or vulnerable to non-use cancellation.

Does my US or EU trademark automatically protect me in China?

No. A US, EU, UK, or other foreign trademark does not automatically give trademark rights in China. It may still be useful evidence in some bad-faith or prior-relationship arguments, but China-side filing status and evidence are usually critical.

Can I still file my own China trademark?

Sometimes yes. Even when a supplier has filed something, there may be room for parallel filing in different classes, subclasses, Chinese-character marks, logos, or uncovered goods. A proper search is needed before deciding whether to file, oppose, invalidate, or combine several routes.

Can trademark opposition or invalidation solve the supplier-control problem?

Trademark procedures may address the trademark record, but they do not automatically solve supplier-control problems. If the issue came from a factory, sourcing agent, distributor, or OEM relationship, you may also need to review contracts, NNN terms, payment path, packaging control, product files, and future supplier access.

What evidence matters if the filing came from my supplier?

Evidence may include emails, Alibaba messages, quotes, invoices, sample records, packaging files, product drawings, factory introductions, prior trademark registrations, and documents showing that the supplier learned the brand from you. The goal is to connect the filing party, the brand, and the prior commercial relationship.

Can China IP Gateway help if my supplier filed my brand?

China IP Gateway can help overseas companies review the China trademark record, understand whether opposition or invalidation may be relevant, assess supplier-side evidence, and identify whether a China trademark conflict review, supplier-control review, or filing strategy is the right next step. Outcomes depend on the facts, timing, evidence, and CNIPA procedure.
