How to Sign Patent Assignment and License Contracts in China: Two CNIPA Templates Explained

Don’t Write Your Patent Contract From Scratch

Many Chinese innovators and companies, when assigning or licensing a patent, grab a random “template” online or patch one together themselves. The result is often missing clauses or clauses that conflict with the Patent Law—problems surfaced only after a dispute. In fact, China’s IP authority has long published two official models—the “Patent (Application) Right Assignment Contract Template and Signing Guide” and the “Patent License Contract Template and Signing Guide”—explaining exactly how to sign properly.

Why These Two Models Were Revised

The original templates, issued years ago, no longer fit the new environment: the Civil Code was enacted, the Patent Law and the Science and Technology Progress Law were amended, and the “Outline for Building a Powerful Intellectual Property Nation (2021–2035)” set new requirements. Meanwhile patent assignment and licensing activity keeps growing, raising enterprises’ expectations for standardized contracts. The revision aims to help parties prevent legal risks, protect their rights, and promote patent commercialization.

What Changed in the Contract Templates

Standardized essential clauses: Essential clauses are fixed as standards, with options for common situations for the parties to choose.

Refined key clauses: For “license mode and scope” in license contracts, details such as term, territory, mode and scope of exploitation are enumerated, with notes on sub-licensing.

Optional extended content: Technology services, training and technology import/export are made optional clauses, used as needed.

What Changed in the Signing Guides

The old guides read like the contract text itself, without explaining clauses. The new versions add notes to every clause: citing relevant legal provisions, flagging points parties should watch, and guiding how to choose the template’s options—essentially an annotated signing manual.

Are They Mandatory?

No. The two models are public-service products from China’s IP authority; they are neither binding regulations nor specific legal advice. Parties may adopt parts, modify them into a customized contract, or draft with professional help.

Formalities After Signing

Assignment requires a recordal of change (registration); a license contract requires filing. Don’t just file it away—without the formality, effect against third parties is weakened. Also keep granted patents alive: use our free patent annuity monitoring to avoid missed payments, and check the China trademark classification lookup before filing trademarks.

Frequently Asked Questions

Are these two contract templates mandatory?

No. They are official public-service products without binding force and do not constitute legal advice; parties may adopt, modify or use them with professional help.

What is the difference between assignment and license?

Assignment transfers ownership (whole or partial) to the other party and requires a recordal of change; a license permits exploitation within agreed scope while ownership stays with the licensor and requires contract filing. Their legal effects and follow-up formalities differ.

What formalities are needed after signing?

Assignment needs a recordal of change; a license needs contract filing. Also monitor annuity payments to avoid termination for non-payment.
