What Stops a Chinese Supplier From Registering My Brand or Design?

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

In short

A dedicated 'no unauthorized IP filing' clause in your China NNN. Many founders focus only on non-disclosure, non-use, and non-circumvention, and forget to explicitly forbid the supplier and its related parties from filing trademarks, designs, patents, copyrights, domains, or platform store names based on your project. Without this clause, a supplier may legally register rights derived from your disclosure.

The Three N's Are Not Always Enough

Founders usually focus on non-disclosure, non-use, and non-circumvention. But there is a fourth protection that is often missing: an explicit ban on the supplier filing IP rights based on your project.

Without this fourth layer, a supplier can argue that it never disclosed, never used in a traditional sense, and never circumvented — but still file a trademark or design in China and claim it legitimately.

What Can Be Filed Against You

Without a no-filing clause, a supplier or related party may file your trademark, your design, a related patent, copyrights in your artwork, domains, or platform store names — and then hold leverage over your own brand.

China's first-to-file system means that the act of filing itself creates rights. Even a bad-faith filing by a supplier can take time and money to undo, and may block your brand position in key channels until resolved.

Make the Clause Explicit and Broad

The clause should cover the supplier and its related parties, and should extend to trademarks, designs, patents, copyrights, domains, and store/account names connected to your project.

Trademarks — including Chinese-character versions of your brand name

Designs — covering your product shape, packaging, and related appearance rights

Patents — including improvements to your disclosed technology

Copyrights — in artwork, labels, packaging, and product imagery you share

Domains and platform store names — any online presence connected to your brand

Peter Lin Insight

The 'no unauthorized IP filing' clause is often the gap between an NNN that looks complete and one that actually protects your brand position in China.

Frequently Asked Questions

Isn't 'non-use' enough to stop IP filing?

Not always. A supplier may argue that filing an application is not 'use' of your confidential information. An explicit no-filing clause closes that gap.

What rights should the clause cover?

Trademarks, designs, patents, copyrights, domains, and platform store or account names — for the supplier and its related parties.
