Patents

Protecting your innovations before manufacturing begins.

China offers three types of patent protection — utility models, invention patents, and design patents — each suited to different types of innovation and different business timelines. Understanding which instrument fits your situation, and when to file, are the two most consequential decisions for foreign innovators working with or entering China.

Guides in this section cover the full practical picture: filing routes, timing relative to manufacturing and supplier engagement, the interaction between patent and trademark protection, and what most foreign product companies get wrong on their first attempt.

Key patent decisions for foreign innovators

Utility model vs. invention patent — which fits your timeline and budget
Design patent — fast protection for product appearance and form
File before disclosing drawings to any supplier or partner
PCT vs. direct China filing — when each approach makes sense
Priority window: 12 months from home-country filing for utility/invention
Patent and trademark protection often need to work together

The Core Issue: Filing Timing Relative to Manufacturing

The most common patent-related mistake foreign companies make in China is not a filing error — it is a timing error. They share product designs with Chinese suppliers before they have filed any patent protection, leaving a window during which a third party can file on their innovation.

China's first-to-file patent system — like its trademark system — rewards those who file early. Your patent rights in China are anchored to your filing date, not to when you invented the product or when you first manufactured it.

The guides in this section are structured around this reality. They explain not just how to file, but when — and what the consequence of each timing decision typically is in practice.

Frequently Asked Questions

Common questions about China patent strategy for foreign innovators and product companies.

What is the difference between a utility model, invention patent, and design patent in China?

Utility models protect functional structures and configurations. They are granted faster (6–12 months) and at lower cost than invention patents, but have a shorter term (10 years) and cannot protect processes or software. Invention patents offer stronger, longer-term protection (20 years) but take 3–5 years to grant. Design patents protect the visual appearance of a product and are often the right instrument for product companies seeking fast, enforceable protection.

Should I file directly in China or use the PCT route?

The PCT route is useful if you want to delay the cost of national-phase filings while maintaining an early priority date across multiple countries. If China is your primary or immediate concern, direct filing may be faster and more cost-effective. If you already have a home-country application, you typically have 12 months (utility/invention) or 6 months (design) to claim priority in China.

Do I need to file a patent before sharing drawings with a Chinese manufacturer?

In most cases, yes. Your filing date — not the grant date — establishes your priority. If you share drawings before filing, a third party could potentially file on your innovation first. A China utility model patent application can be filed quickly and covers the period while the application is pending. File first, then disclose.

Can I rely on trade secrets instead of patents when working with Chinese manufacturers?

Trade secret protection is possible but requires careful structuring — specific agreement language, internal procedures, and documented handling of confidential materials. It is generally stronger as a complement to registered IP rather than a substitute. For product features with significant commercial value, registration is usually the more reliable path.
