How to File a Patent in China (and Why You Should): A Guide for Foreign Businesses

Updated April 2026 · By Jing — bilingual, based in Guangdong, China

If you manufacture or sell products in China, or plan to in the future, filing a Chinese patent is not optional — it’s a critical step to protect your intellectual property (IP) and prevent competitors from copying your product. China operates under a first-to-file patent system, which means whoever files the patent first owns the rights to the invention, even if you invented it first.

This guide breaks down everything you need to know about filing a patent in China: the different types of patents, costs, timelines, how to find a reliable attorney, and what happens if you don’t file.

Why File a Patent in China First?

Many foreign founders make the mistake of only filing patents in their home country, only to find out a Chinese competitor has copied their product and filed a patent in China first — leaving them with no legal recourse. Here’s why you need to file in China first:

• First-to-file system: As mentioned above, China grants patents to the first person who files, not the first person who invents. If a competitor files your patent before you do, they own the rights to it in China, even if you can prove you invented it first.
• Manufacturing protection: 90% of consumer electronics, 70% of household goods, and 60% of industrial products are manufactured in China. If you don’t have a Chinese patent, a factory can copy your design and sell it to other customers, or even sell counterfeit versions of your product directly on global marketplaces like Amazon and Alibaba.
• China market access: If you want to sell your product in China, you need a Chinese patent to stop counterfeiters from selling copies on Taobao, JD, and Douyin. Chinese e-commerce platforms will only take down counterfeit listings if you have a valid Chinese patent.
• Global enforcement: Chinese patents are recognized in 178 countries under the Paris Convention for the Protection of Industrial Property. You can use your Chinese patent filing date as a priority date when filing patents in other countries.
• Lower costs: Filing a patent in China is 50-70% cheaper than filing in the US or EU, and the process is faster for utility model and design patents.

3 Types of Chinese Patents: Which One Do You Need?

China has three types of patents, each designed for different kinds of inventions:

1. Utility Model Patent

This is the most popular patent for hardware products, as it is cheap, fast to approve, and provides strong protection for product structures and functions.

• What it covers: New technical solutions relating to the shape, structure, or combination of a product. It does not cover manufacturing processes, formulas, or software algorithms.
• Best for: Consumer electronics, IoT devices, mechanical products, tools, and any product with a unique physical structure.
• Approval rate: ~70% (much higher than invention patents)
• Protection term: 10 years from the filing date

2. Invention Patent

This is the highest level of patent protection in China, for groundbreaking inventions and new technologies.

• What it covers: New technical solutions for products, processes, or improvements thereof. It covers everything a utility model covers, plus manufacturing processes, formulas, software algorithms, and chemical compositions.
• Best for: New materials, pharmaceutical products, manufacturing processes, AI algorithms, and any invention that is a significant improvement over existing technology.
• Approval rate: ~40% (much stricter examination process)
• Protection term: 20 years from the filing date

3. Design Patent

This protects the visual appearance of a product, not its function.

• What it covers: The shape, pattern, color, or combination thereof of a product that is aesthetically pleasing and suitable for industrial application.
• Best for: Product packaging, furniture, clothing, toy designs, consumer electronics casings, and any product with a unique visual design.
• Approval rate: ~80%
• Protection term: 15 years from the filing date

Cost Breakdown: USD vs CNY Comparison Table

All costs below include official government fees + attorney fees for a standard patent application. Prices are for foreign applicants, with English-language support.

Additional optional costs:

• Patent search: $300-$1,000 USD (¥2,160-¥7,200 CNY) to check if your invention is already patented in China. Highly recommended before filing.
• Priority claim fee: $100 USD (¥720 CNY) if you want to use your home country patent filing date as the priority date for your Chinese application.
• Annual maintenance fees: $50-$500 USD (¥360-¥3,600 CNY) per year, depending on the patent type and how many years it has been in force.

Timelines: How Long Does Each Patent Take to Approve?

Expedited Examination Options

If you need your patent approved faster, you can apply for expedited examination for an extra fee:

• Utility model/design: Can be approved in as little as 2 months for an extra $500-$1,000 USD fee.
• Invention: Can be approved in as little as 6 months for an extra $1,500-$3,000 USD fee, if your invention is in a high-tech field (semiconductors, AI, clean energy, medical devices).

China's First-to-File System: What It Means for You

Unlike the US, which operates under a first-to-invent system, China grants patents to the first person who files the application, regardless of who invented the product first. This has a number of critical implications for foreign founders:

1. File before you show your product to anyone: Never share your product design with factories, suppliers, or potential customers before you have filed a patent application in China. Even a single post on social media or a demo at a trade show can give a competitor enough information to file your patent before you do.
2. File as early as possible: You don’t need a perfect, mass-production-ready design to file a patent. You only need a clear description of the invention and how it works. File a provisional application first if you are still refining your design — this will lock in your priority date for 12 months, giving you time to finalize your product.
3. Don’t rely on your home country patent: A US or EU patent does not protect you in China. You must file a separate patent application in China to get protection here.
4. Monitor for patent squatting: Regularly search the Chinese patent database (CNIPA) to make sure no one is filing patents on your invention. If you find someone has filed your patent before you, you can file an opposition within 3 months of the patent being published.

How to Find a Reliable Chinese Patent Attorney

Your patent attorney is the most important factor in a successful patent application. Here’s how to find a good one:

1. Look for a licensed patent attorney with experience working with foreign clients: All Chinese patent attorneys must be licensed by the China National Intellectual Property Administration (CNIPA). Check their license number on the CNIPA website before hiring them.
2. Avoid cheap, unlicensed agents: There are many unlicensed agents who offer patent filing services for very low prices, but they often draft low-quality applications that will be rejected by CNIPA, or don’t provide enough protection.
3. Ask for references from other foreign founders: Ask other hardware founders in your network for recommendations for patent attorneys who have experience in your industry.
4. Make sure they speak fluent English: You need to be able to communicate clearly with your attorney about the technical details of your invention.
5. Get a fixed fee quote upfront: Most reputable attorneys will give you a fixed fee quote for the entire application process, including drafting, filing, examination, and response to office actions. Avoid attorneys who charge by the hour, as costs can spiral out of control.

For Guangdong-based businesses, we recommend working with local attorneys who have experience with Guangdong’s high-tech industry — they will be more familiar with the specific needs of hardware and manufacturing companies.

What Happens If You Don't File and Someone Copies Your Product?

If you don’t have a Chinese patent and someone copies your product, you have almost no legal recourse in China:

1. You can’t stop factories from manufacturing copies: Chinese courts will only issue injunctions against factories if you have a valid Chinese patent. Without one, factories can legally copy your product and sell it to anyone they want.
2. You can’t take down counterfeit listings from Chinese e-commerce platforms: Taobao, JD, and Douyin will only remove counterfeit listings if you provide a valid Chinese patent certificate.
3. You can’t sue counterfeiters for damages: Chinese courts will only award damages for patent infringement if you have a valid Chinese patent. Without one, you can’t claim any compensation for lost sales.
4. You may be accused of patent infringement: If the counterfeiter filed a patent on your product before you did, they can sue you for patent infringement when you import your own product into China, or even when you export products manufactured in China to other countries.
5. You will lose market share: Counterfeit products are often sold for 50-80% less than the original product, and will quickly eat into your sales in both China and global markets.

We have seen many foreign founders lose millions of dollars in revenue because they didn’t file a Chinese patent, only to have their product copied and sold by competitors within months of launching.

Guangdong Insider Tips for Patent Filing

1. File both a utility model and an invention patent for hardware products: Utility model patents are approved quickly, giving you immediate protection, while invention patents provide longer-term, broader protection. You can file both at the same time, and abandon the utility model once the invention patent is approved.
2. File design patents for every part of your product: Even if you have a utility model or invention patent, filing a design patent for the casing, packaging, and user interface of your product will give you extra protection against counterfeiters.
3. Use Guangdong’s patent subsidy programs: The Guangdong provincial government and Shenzhen municipal government offer subsidies of up to ¥10,000 RMB ($1,380 USD) per patent for foreign companies that file patents in Guangdong. Your patent attorney can help you apply for these subsidies, which can cover up to 100% of your filing costs.
4. Register your patent with Chinese customs: Once your patent is approved, register it with China Customs. They will seize any counterfeit products that try to leave or enter China, preventing counterfeiters from selling your product in global markets.
5. Do a patent search before you start designing your product: Many foreign founders spend months designing a product, only to find out it is already patented in China. Doing a patent search early will save you time and money.

5 Frequently Asked Questions

Q1: Do I need to be based in China to file a patent?

No, foreign individuals and companies can file patents in China without being residents or having a business entity in China. You will need to work with a licensed Chinese patent attorney to file the application on your behalf.

Q2: Can I file a patent in China if I already filed one in my home country?

Yes, you can file a patent in China within 12 months of your home country filing date, and claim priority to your home country filing date. This means your Chinese patent will be treated as if it was filed on the same date as your home country patent.

Q3: How do I know if my invention is patentable in China?

Your invention must be novel (not disclosed publicly anywhere in the world before the filing date), inventive (not obvious to a person skilled in the relevant field), and practical (can be manufactured or used in industry). Your patent attorney can do a patent search to assess the patentability of your invention.

Q4: Can I enforce my Chinese patent in other countries?

No, a Chinese patent only provides protection in China. However, you can use your Chinese patent filing date as a priority date when filing patents in other countries under the Paris Convention.

Q5: What if my patent is rejected by CNIPA?

You can file a request for re-examination within 3 months of receiving the rejection notice. If the re-examination is also rejected, you can appeal to the Beijing Intellectual Property Court. Your attorney will advise you on the best course of action.

Common Mistakes to Avoid

1. Waiting too long to file: As mentioned earlier, China’s first-to-file system means you should file your patent application as soon as you have a clear description of your invention. Don’t wait until you have a perfect prototype.
2. Disclosing your invention before filing: Any public disclosure of your invention (trade show demo, social media post, crowdfunding campaign, even a private conversation with a potential supplier) can invalidate your patent application. File before you disclose anything to anyone.
3. Using a generic patent template: Many founders try to save money by using a generic patent template they found online, but this will almost always result in a low-quality application that provides little to no protection. A good patent attorney will draft a custom application that covers all aspects of your invention and maximizes your protection.
4. Forgetting to pay annual maintenance fees: If you don’t pay the annual maintenance fees for your patent, it will become invalid, and you will lose all protection. Set up automatic reminders to pay the fees every year.
5. Not monitoring for infringement: Once your patent is approved, you need to regularly monitor the market for counterfeit products. If you find counterfeits, you need to take action quickly to stop them, as waiting too long can weaken your legal position.
