How to Protect Your Intellectual Property When Manufacturing in China
China is first-to-file for trademarks and patents. If you haven't registered before you share your design, you may have already lost it. Here's the playbook.
The most expensive IP mistake an overseas buyer makes is assuming that rights acquired at home protect them in China. For trademarks and patents, China operates on a first-to-file basis: whoever registers first generally owns the right — and a factory that registers your brand before you do can end up owning it, or holding it hostage.
Register first, share later
File your trademark (with the China National Intellectual Property Administration, CNIPA) and any relevant design or utility-model patents before you disclose your brand, logo, or design to a factory. Chinese registration protects you only in China — your home-country registration does not extend there.
- Trademark — protects your brand name and logo; register in the relevant classes.
- Design patent — protects the appearance of a product.
- Utility model / invention patent — protects function and technical solutions.
- Copyright — automatic in some respects but worth recording for enforcement.
Use the NNN agreement
The 'NNN' agreement (Non-disclosure, Non-use, Non-circumvention) is the standard confidentiality instrument in China manufacturing. Before sharing drawings, molds, or customer lists, have the factory sign an NNN that forbids it from disclosing, using, or selling around your IP. Combine it with an IP clause in your supply contract.
Control your molds and tooling
If you pay for molds, the contract should state that you own them, that the factory holds them only for your production, and that they must be returned or destroyed on termination. Mark molds and tooling with your identifiers and photograph them.
Monitor and enforce
- Watch for your brand or design appearing on marketplaces (Alibaba, 1688, Taobao) or at trade shows.
- Record your trademarks with China Customs so they can seize infringing exports at the border.
- Act promptly — enforcement is easier against early, small infringers than established ones.
If a factory has already registered your brand in China, don't despair — a 'bad-faith registration' can sometimes be challenged, and there are preemptive and defensive filings available. Act quickly with local counsel.
IP protection in China is real and improving — but it is proactive, not automatic. Registration, confidentiality agreements, and monitoring are the three pillars. The buyers who treat IP as a pre-deal step, not an afterthought, are the ones who keep their brands.
