1. What Are the Types of Patents in China?
Understanding Patent Categories
China’s patent system, managed by the China National Intellectual Property Administration (CNIPA), offers three types of patents, each suited for different innovations. First, invention patents protect new technical solutions, like a groundbreaking AI algorithm, for 20 years from the filing date. They undergo strict checks for novelty and utility, making them ideal for major innovations. Next, utility model patents cover smaller improvements, such as a new tool design, and last 10 years. They’re easier and cheaper to get but offer narrower protection. Finally, design patents safeguard a product’s look, like a unique phone shape, for 15 years, extended in 2020.
Choosing the Right Patent for Your Business
Selecting the right patent depends on your goals. For example, a tech company might buy an invention patent for a new software feature, while a fashion brand might choose a design patent for a unique bag style. According to the ChinaPower Project, CNIPA processed 1.59 million patent applications in 2021, with invention patents being highly valued for their strategic impact. Therefore, align your purchase with your product’s market needs.
Legal Clause:
Article 2 of the Patent Law of the People’s Republic of China defines invention, utility model, and design patents, outlining their eligibility criteria.
By understanding these categories, you can make a smart choice. For tailored advice, explore our patent and design services at YCIP.
2. Why Is Due Diligence So Important?
The Risks of Skipping Due Diligence
Due diligence is like checking a car before buying it—you need to know it works. When buying a patent in China, you must verify it’s valid and free from issues. Without this step, you might purchase a patent that’s already in a legal dispute or even invalid. For instance, a U.S. company once bought a Chinese patent without checking prior art, only to find it was based on existing technology, wasting their investment.
Key Steps in Due Diligence
To avoid problems, follow these steps:
- Verify Ownership: Check CNIPA records to confirm the seller owns the patent and it’s free from liens, as noted by Lexology.
- Search for Disputes: Look for any lawsuits or invalidation claims against the patent.
- Review Contracts: Examine licenses or employee agreements tied to the patent.
- Prior Art Search: Use CNIPA’s Patent Search and Analysis System and global databases like WIPO to ensure the patent is unique.
Legal Requirement:
Article 18 A of the Patent Law mandates that foreigners without a China-based office must use a Chinese patent agency for due diligence and other patent matters.
Working with a trusted agency, like those listed by the YCIP team, ensures thorough checks and compliance.
3. How Do China’s Patent Laws Work?
Key Legal Provisions
China’s patent system is governed by the Patent Law of the People’s Republic of China, updated in 2020 and effective June 1, 2021. This law sets rules for buying and transferring patents. For example, Article 10 requires a written contract for patent transfers, which must be registered with CNIPA to be valid. Additionally, Article 18 A states that foreign buyers without a local presence must use a Chinese patent agency, like Tingfei Wang at YCIP, for all patent matters.
Stronger Protections Since 2020
The 2020 amendment also boosted protections. For instance, Article 71 allows courts to award damages from RMB 30,000 to RMB 5 million (about $4,200 to $700,000) for patent infringement, with up to five times more for intentional violations. Moreover, transfers to foreign entities may need approval under China’s export control laws, especially for sensitive tech, as noted in China IP Law Update. These rules make your patent purchase safer but require careful compliance.
Why It Matters: Registering your transfer with CNIPA ensures your ownership is legally recognized. For help navigating these laws, check our consultation and litigation support services.
4. How Much Is a Patent Worth in China?
Factors Affecting Patent Value
Valuing a patent in China depends on several factors. First, China’s massive 1.4 billion population and growing middle class make patents in consumer goods, tech, and biotech highly valuable, according to Harris Sliwoski LLP. Second, patents in trending fields like AI or pharmaceuticals fetch higher prices due to demand. Third, enforcement potential matters—since 2020, courts like Beijing’s IP Court have increased average damages from $80,000 in 2018 to $450,000 in 2022, per Panitch Schwarze.
Market Trends and Valuation
China’s IP market is booming. In 2019, China filed 1.4 million patents, 43.4% of the global total, as reported by CIGI. Additionally, China’s IP financing market reached 486.9 billion Chinese yuan in 2022, growing 28.4% yearly, according to IAM. These trends show Chinese patents are now often valued as highly as U.S. patents, especially in tech. For example, a patent for a new app feature might cost more due to its market potential.
Why It Matters: Understanding value helps you budget and negotiate. For expert valuation, contact our licensing and transaction specialists at YCIP.
5. What Mistakes Should You Avoid?
Common Pitfalls in Patent Purchases
Buying a patent in China can be tricky, and mistakes can cost you money or even the patent itself. First, skipping due diligence is a big error. Without checking, you might buy a patent that’s invalid or tied up in lawsuits. For example, a foreign company once bought a utility model patent but didn’t check its status, only to find it had expired due to unpaid fees. Next, missing maintenance fees is another trap. Patents in China require annual payments, and forgetting them means losing your rights. Additionally, misunderstanding legal rules, like not registering the transfer with CNIPA, can void the deal. Finally, language barriers can lead to misreading contracts, causing disputes.
How to Avoid These Mistakes
To stay safe, always work with a Chinese patent agent, as required by Article 18 A of the Patent Law. They can verify ownership, check for disputes, and ensure fees are paid. Also, use CNIPA’s public databases to confirm the patent’s status. For instance, our patent and design services at YCIP include thorough checks to avoid these pitfalls. Moreover, hire experts like Peter H. Li, our IP specialist, to navigate language and cultural nuances. By taking these steps, you can protect your investment and avoid costly errors.
Legal Clause:
Article 10 of the Patent Law mandates that patent transfers must be registered with CNIPA to be effective, ensuring legal ownership.

6. Why Do You Need a Patent Agent?
The Role of Patent Agents
A patent agent is like a guide who helps you navigate China’s patent system. For foreign buyers, they’re essential because the law requires them. They handle legal tasks, like filing transfer papers with CNIPA, and check if the patent is valid. Additionally, they bridge language gaps, explaining complex Chinese terms clearly. For example, our team at Tony Xu specializes in litigation and can ensure your patent purchase is legally sound. Without an agent, you risk missing critical steps, like registering your transfer.
Benefits of Working with YCIP
Partnering with a trusted agency, like those listed by the All-China Patent Agents Association (ACPAA), saves time and reduces risks. At YCIP, our core professional team conducts due diligence, verifies ownership, and prepares contracts. This ensures compliance with laws and protects your investment.

Therefore, choosing YCIP means peace of mind and a smoother process.
Legal Requirement:
Article 18 A of the Patent Law requires foreign entities without a China-based office to use a legally established patent agency for all patent matters.
7. How Can You Protect Your Patent?
Enforcement Options in China
Once you own a patent, protecting it from copycats is crucial. China offers three main ways to enforce your patent. First, you can file a lawsuit in specialized IP courts in Beijing, Shanghai, or Guangzhou. These courts are tough on infringers, with Beijing’s IP Court awarding an average of $450,000 per case in 2022, up from $80,000 in 2018, according to Panitch Schwarze. Second, register your patent with the General Administration of Customs (GAC) to block fake products at borders, valid for 10 years. Third, CNIPA can order infringers to stop, offering a faster, cheaper option.
Practical Steps for Protection
To maximize protection, register your patent with GAC and monitor the market using tools like Red Points’ IP Software, as noted by Red Points. Also, work with our litigation support team to build a strong case. The 2020 amendment strengthened enforcement, with Article 71 allowing damages up to RMB 5 million (about $700,000) and punitive damages for intentional infringement. For example, Shanghai’s IP Court handled 119 cases in 2022 with damages over $1.4 million, showing robust protection options.
Legal Clause:
Article 71 of the Patent Law outlines remedies, including compensation, injunctions, and reasonable expenses to stop infringement.
8. What’s New in China’s Patent Laws?
Key Changes from 2020
The 2020 amendment to China’s Patent Law, effective June 1, 2021, brought big changes for patent buyers. First, design patents now last 15 years instead of 10, per Article 42(1). Second, an open license system lets patent owners offer their patents for public use with set fees, reducing annuity costs, as outlined in Articles 50–52. Third, patent term compensation covers delays in examination or drug approvals, up to 5 years, per Article 42(2–3). Finally, Article 71 increased damages for infringement, ranging from RMB 30,000 to RMB 5 million, with punitive damages for intentional violations.
Impact on Buyers
These changes make patents more valuable. For instance, longer design patent terms benefit industries like fashion, while stronger damages deter copycats. In 2021, China filed 1.4 million patents, over half the global total, per Our World in Data. Additionally, a 6-month novelty grace period for public disclosures during emergencies, per Article 24(1), adds flexibility. Learn more about these updates in our CNIPA guide.
Legal Clause:
Article 42(1) of the Patent Law extends design patent protection to 15 years, enhancing their value for buyers.
9. Should You Buy or License a Patent?
Buying vs. Licensing: Key Differences
Deciding whether to buy or license a patent depends on your goals. Buying gives you full ownership, letting you use, enforce, or sublicense the patent. It’s great for long-term plans but comes with high upfront costs and maintenance fees. Licensing, on the other hand, lets you use the patent without owning it, paying royalties instead. It’s cheaper initially but offers less control. For example, a startup might license a patent to test a product, while a big tech firm might buy one for exclusive control.
Which Option Suits You?
In 2019, Chinese enterprises had a 6.1% patent licensing rate, compared to 2.9% for universities, per CIGI. Licensing agreements must follow CNIPA rules, and foreign licensors face antitrust scrutiny, as noted by International Technology Law Blog. If you want flexibility, licensing is better; for exclusivity, buying is the way to go. Our licensing and transaction services can help you decide.
Legal Consideration:
Article 10 of the Patent Law requires licensing agreements to be registered with CNIPA for legal effect.
