How to Protect Your Intellectual Property When Manufacturing in China

Identify the Intellectual Property You Need to Protect

Manufacturing in China offers important opportunities for international businesses. However, working with a Chinese manufacturer often requires sharing valuable commercial information, including trademarks, product designs, technical drawings, packaging artwork, and manufacturing specifications.

Before signing a manufacturing agreement, identify the intellectual property involved in your project. This may include: brand names and logos; product designs and technical drawings; patents and patentable inventions; packaging artwork and copyrighted materials; confidential manufacturing information; and customer information and proprietary specifications.

Different types of intellectual property are protected under different legal rules. For example, trademark ownership, patent rights, copyright ownership, and trade secret protection should not be treated as identical legal issues.

Clarify Ownership of Existing and Newly Developed IP

One of the most important issues in a China manufacturing agreement is ownership of intellectual property.

A contract should distinguish between: Background IP — intellectual property owned by either party before the manufacturing project or developed independently of it; and Project IP — intellectual property created specifically for the project.

This distinction matters because paying a manufacturer to develop a product does not necessarily mean that the buyer automatically owns every resulting intellectual property right. Depending on the type of work and applicable Chinese law, ownership may be governed by statutory default rules unless the parties agree otherwise.

A well-drafted contract should identify relevant deliverables, ownership arrangements, permitted uses, and any required assignment or registration procedures.

Protect Your Trademarks Before Sharing Your Brand

A foreign trademark registration does not automatically provide registered trademark protection in China.

Before sending branded packaging or product specifications to a Chinese manufacturer, consider conducting a Chinese trademark search and evaluating whether registration is appropriate.

Your manufacturing agreement should also address the manufacturer's permitted use of your brand. For example, it may prohibit the manufacturer from applying to register the buyer's trademarks or confusingly similar marks without authorization.

Include Appropriate Confidentiality and Use Restrictions

Foreign buyers often provide manufacturers with information that may have significant commercial value. This could include product specifications, technical drawings, sourcing information, and confidential production processes.

A confidentiality agreement can help, but effective protection requires more than a general promise not to disclose information.

Consider addressing: what information is confidential; who may access the information; whether subcontractors may receive it; what uses are permitted; how information must be stored and protected; and what happens when the manufacturing relationship ends.

Under Chinese law, trade secret protection depends on statutory requirements, including appropriate confidentiality measures.

Prohibit Unauthorized Production and Sales

Some businesses are concerned that a manufacturer may produce additional units without authorization or sell branded products to third parties.

A manufacturing agreement should clearly define authorized production quantities and permitted distribution channels. Where appropriate, it should also prohibit unauthorized use of the buyer's trademarks, protected designs, confidential information, and tooling.

Production records, inventory controls, and reasonable audit rights can help support these contractual obligations.

Address Tooling, Molds, and Product Files

Manufacturing projects often involve molds, tooling, prototypes, and electronic design files. Disputes can arise when the business relationship ends and the buyer wants to move production to another factory.

The agreement should clarify: who owns the tooling and molds; who pays for their development and maintenance; whether the manufacturer may use them for other customers; when they must be returned or transferred; and how electronic files and confidential information will be handled.

Ownership of physical tooling and ownership of intellectual property rights are separate questions and should be addressed accordingly.

Plan for Disputes Before They Occur

A manufacturing agreement should also address governing law, dispute resolution, evidence preservation, and available remedies.

The appropriate dispute resolution mechanism depends on the parties, location of assets, type of dispute, and enforcement considerations.

A clause that appears favorable on paper may be less useful if it is difficult to enforce in practice.

How Can a China-Qualified Lawyer Help?

A China-qualified lawyer can help foreign businesses identify legal risks in manufacturing agreements and assess whether the contract adequately addresses intellectual property ownership, confidentiality, authorized production, and dispute resolution.

Services may include: reviewing existing supplier agreements; drafting or revising intellectual property provisions; assessing trademark and design ownership risks; reviewing confidentiality and non-use obligations; and advising on contractual remedies and dispute prevention.

The appropriate scope depends on the products, commercial arrangements, and intellectual property involved.
