Patent License vs Know-How License: Which Licensing Approach?
In China, over 250,000 technology licensing agreements are registered annually with the Ministry of Commerce, but choosing between a patent license (专利许可, zhuānlì xǔkě) and a know-how license (技术诀窍许可, jìshù juéqiào xǔkě) can make or break your market entry strategy. The decision affects royalty rates, tax treatment, registration timelines, and enforcement options in a country where IP theft costs foreign firms an estimated $50 billion annually. This comparison breaks down the critical differences so you can align your licensing approach with your business goals.
To put the scale in context, patent licenses in China typically carry royalty rates of 2–5% of net sales, while know-how licenses command 3–8% due to their secrecy value. However, know-how licensing requires strict confidentiality controls, often raising legal costs by 15–25% compared to patent-only agreements. The table below provides a head-to-head comparison across eight key decision factors.
Defining Patent and Know-How Licenses in China
A patent license (专利许可, zhuānlì xǔkě) grants rights to a registered invention, utility model, or design that is publicly disclosed and legally protected by the China National Intellectual Property Administration (CNIPA). Patent terms in China are 20 years for inventions and 10 years for utility models and designs, after which the technology enters the public domain. Because the invention is published in the patent gazette, enforcement relies on the claims recorded in the patent document.
A know-how license (技术诀窍许可, jìshù juéqiào xǔkě) covers proprietary technical information—such as formulas, processes, or algorithms—that is kept secret and not protected by any patent. Know-how protection hinges on confidentiality agreements and trade secret laws under China’s Anti-Unfair Competition Law. Unlike patents, know-how has no fixed term; it lasts as long as the information remains secret. This creates both opportunity (no expiry) and risk (loss of secrecy can destroy value overnight).
In practice, many foreign execs choose a hybrid approach: they license both a patent portfolio and associated know-how to maximize IP protection while ensuring the licensee can effectively implement the technology. However, hybrid agreements must be carefully structured to avoid conflicting registration and tax treatments.
Key Comparison: Legal Protection, Registration, and Tax Treatment
| Dimension | Patent License | Know-How License |
|---|---|---|
| Legal basis | Patent Law of China (CNIPA registration required) | Anti-Unfair Competition Law + contract law |
| Registration with MOFCOM | Mandatory within 30 days of signing | Mandatory within 60 days (if cross-border) |
| Royalty rate range | 2–5% of net sales | 3–8% of net sales |
| Withholding tax (WHT) | 10% on outbound royalties (treaty relief possible) | 10% on outbound royalties (treaty relief possible, but stricter scrutiny) |
| Cost of registration | RMB 3,000–8,000 per agreement | RMB 5,000–15,000 per agreement (due to confidentiality review) |
| Duration of protection | 20 years (invention) / 10 years (utility model) | Indefinite, while secrecy is maintained |
| Enforcement speed | 6–12 months via CNIPA administrative action | 12–24 months via court injunction |
| Scope of exclusivity | Territorial (China only, unless PCT extension) | Contractual (defined by agreement terms) |
The table reveals that patent licenses offer faster enforcement and clearer legal protection, while know-how licenses provide longer potential duration but higher upfront costs and slower remedies. Tax treatment is similar at standard rates, but know-how royalties face deeper scrutiny from the State Administration of Taxation due to valuation difficulty.
Decision Framework: Which Licensing Approach for Your China Strategy?
Choosing between patent and know-how licenses depends on your technology’s maturity, registration status in China, and the level of control you need. Use the following framework to match your situation with the optimal approach.
If your technology is already patented in China (or you are filing within 12 months), choose a patent license. This gives you immediate enforcement rights through CNIPA administrative actions, which can stop infringement within 6 months at a cost of RMB 10,000–50,000. It also simplifies tax filings because the royalty rate is benchmarked against comparable patents.
If your technology is not patented, or the patent has expired, but the know-how remains valuable, choose a know-how license. This is ideal for process innovations, confidential formulas, or trade secrets that are difficult to reverse-engineer. However, you must invest in a robust confidentiality agreement (NDA) with penalties of at least RMB 500,000 per breach to ensure enforceability in Chinese courts.
If you have both patents and know-how covering the same product, choose a hybrid license with separate royalty streams. For example, a 3% royalty on the patent component and a 4% royalty on the know-how component, each registered independently with MOFCOM. This allows you to maintain patent protection while leveraging know-how secrecy for the core process.
If your licensee is a state-owned enterprise (SOE) or large Chinese manufacturer, prefer a patent license because SOEs often have internal policies against binding trade secret agreements. Patents provide a transparent, court-backed mechanism that aligns with their compliance frameworks.
3 Common Pitfalls in China Licensing
Real-World Case: Automotive Components Joint Venture
A German auto parts supplier entered a joint venture with a Chinese manufacturer to license its patented braking system and associated know-how for production. Initially, the German firm proposed a pure patent license with a 4% royalty. However, the Chinese partner insisted on the know-how to replicate the manufacturing process. The resulting hybrid agreement included a 2.5% patent royalty plus a 4% know-how royalty, registered separately with MOFCOM.
The patent component was registered in 28 days, while the know-how registration took 55 days due to confidentiality review by the technology import authorities. Over the first 12 months, the JV generated RMB 120 million in sales, resulting in royalty payments of RMB 7.8 million. The German firm encountered two issues: the Chinese licensee attempted to sublicense the know-how without consent, triggering the liquidated damages clause (RMB 500,000 penalty), and the tax bureau challenged the know-how royalty valuation, leading to a delayed remittance of RMB 1.2 million until documentation was provided. The lesson: hybrid licenses maximize revenue but require airtight contractual safeguards and meticulous compliance.
Timeline and Registration Requirements
The registration timeline for a patent license is typically 30–60 days from submission to MOFCOM, while a know-how license takes 60–90 days due to additional technology import review. For both types, you need the following documents: signed license agreement (Chinese and English), patent certificate or know-how description, business license of both parties, and a technology import contract application form. The cost ranges from RMB 3,000 to RMB 15,000 per agreement, depending on the complexity and need for a Chinese translator.
Since 2020, China has streamlined the registration process through the “single window” system, reducing processing times by 20–30%. However, failure to register can result in fines of RMB 50,000–300,000 and the inability to remit royalties abroad. In 2023, over 15% of foreign firms surveyed reported delays in royalty payments due to incomplete registration documentation.
NEXT STEPS
- Review your existing IP portfolio — Conduct a China-specific IP audit to identify which technologies are patented (or patentable) and which should remain as know-how. Use this to create a map of licensing options. Read our China IP Audit Checklist Guide
- Draft a compliance-ready license agreement — Include MOFCOM registration timelines, confidentiality clauses with liquidated damages, and tax treaty provisions. Work with a China-qualified attorney who specializes in technology import/export. View our China License Agreement Template
- File for tax treaty benefits before first royalty payment — Obtain a tax resident certificate from your home country and submit it to the Chinese tax bureau to lower withholding tax from 20% to 10% (or lower under applicable treaties). Learn about China Royalty Remittance Procedures
