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 former business partner filed your brand in China, confirm the applicant's identity and preserve evidence of the prior relationship before confronting them. The procedural route still depends on the CNIPA status, but this page focuses on what the commercial relationship, earlier disclosure, and supplier-control structure add to the analysis.

First, confirm what actually happened

Verify the official CNIPA record, then test whether the applicant name connects to the supplier relationship you know. For the general filed-versus-registered status analysis and short explanations of opposition, invalidation, non-use cancellation, parallel filing, and negotiation, use the core China trademark conflict answer.

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, match the relationship evidence to the procedural stage

The stage determines the procedure; the supplier relationship may affect the evidence and grounds. The points below are issue-spotting directions, not automatic remedies.

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

Confirm any publication deadline promptly, then assess whether the prior supplier relationship and preserved evidence support relevant opposition grounds.

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

Review whether the relationship evidence supports an invalidation ground. If the registration has reached the applicable three-year threshold, genuine use for the blocking goods may also need investigation; cancellation is not automatic.

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

Check whether your own word mark, logo, Chinese-character mark, classes, or subclasses remain open. A parallel filing may build position but does not by itself resolve the supplier-filed record.

If Chinese-character marks are involved — check those separately

Check the English mark, logo, and any Chinese-character name separately, including whether the supplier encountered or helped create that name through the relationship.

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?

Confirm the CNIPA record and whether the applicant is actually connected to your supplier, factory, distributor, sourcing agent, or former partner. The general procedural route still depends on the filing date, class, subclass, and current status; this page focuses on the relationship and evidence layer.

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.
