Manufacturing & Supplier Risk
How to protect your IP before and during factory engagement.
Chinese manufacturing creates IP exposure that is structurally different from sourcing in other markets. The density of supply chain networks, the first-to-file IP system, and the limitations of standard Western agreements combine to create a specific risk profile — one that most foreign companies underestimate until they encounter a problem.
Guides in this section cover the practical layer: how to structure disclosure, what agreements to use and why, when to act, and what the key risks are at each stage of factory engagement.
Key issues at the manufacturing stage
- NNN agreements — not NDAs — are the right instrument for Chinese manufacturing
- File patents before sharing product drawings or technical specs
- Tooling and mold ownership must be explicitly addressed in your agreement
- OEM buyers face specific IP risks that standard agreements don't cover
- Supplier non-circumvention protects your supply chain relationships
- Agreement timing: protection must come before disclosure, not after
Why Manufacturing IP Risk in China Is Structurally Different
IP loss in Chinese manufacturing is rarely dramatic. It is usually gradual and structural: a supplier producing your product for a lower-cost competitor, tooling used across multiple customers without your knowledge, or a factory registering your product design before you do.
These outcomes are not prevented by goodwill or commercial relationships. They are prevented by agreements that create explicit, China-enforceable obligations before any sensitive information changes hands.
The guides in this section focus on pre-manufacturing action: the agreements, registrations, and disclosures controls that need to be in place before factory conversations begin — not after a problem has surfaced.

Read GuideFrequently Asked Questions
Common questions about IP protection during Chinese manufacturing engagement.
Why is a standard NDA often insufficient when working with Chinese manufacturers?
Standard NDAs drafted for Western jurisdictions typically cover only non-disclosure. They often lack specific restrictions on non-use (using your IP to produce for others) and non-circumvention (going around you to access your clients or suppliers directly). They may also include jurisdiction or governing law clauses that are difficult or expensive to enforce in China. An NNN agreement addresses all three dimensions explicitly.
What should an NNN agreement cover that a standard NDA does not?
A well-structured NNN agreement should explicitly prohibit: disclosing your confidential information; using your IP, tooling, or production knowledge to manufacture for others; and circumventing you to work directly with your customers or upstream suppliers. It should be governed by Chinese law, specify a Chinese venue for disputes, and include deterrent-level liquidated damages that make breach economically irrational.
Who owns the tooling and molds made for my product in a Chinese factory?
By default, the rules are often ambiguous unless explicitly addressed in your manufacturing agreement. Without a clear written agreement, a factory may claim ownership of tooling it made, even if you paid for it. Your agreement should explicitly state that all tooling, molds, dies, and matrices produced using your funds or specifications are your property, and that they may not be used for other customers.
When is the right time to put agreements in place — before or after selecting a supplier?
Before. IP protection conversations and documentation should happen at or before initial disclosure — not after you have narrowed to a preferred supplier. This is when you are most likely to be disclosing meaningful technical or design information. Waiting until the supplier is selected often means you have already disclosed the most sensitive content without protection.
