How to Register a Patent in China: Invention, Utility Model, and Design Patents for Foreign Companies (2026)

For a foreign company doing business in China, patents are among the most valuable — and most commonly neglected — assets. China operates a strict first-to-file system, which means the party that files a valid application first generally holds the right, regardless of who invented the technology first. If you develop products, manufacturing processes, or industrial designs in or for the Chinese market, filing early is not optional; it is the single most important step you can take to protect your innovation. This guide explains the three types of Chinese patents, what they cost, how the application process works, and what foreign applicants must do to file correctly in 2026.

Key Facts

• Invention patent term: 20 years from the filing date.
• Utility model term: 10 years from the filing date.
• Design patent term: 15 years from the filing date.
• Invention grant timeline: roughly two to three years, including an 18-month publication window.
• Foreign filing rule: overseas applicants must file through a licensed Chinese patent agency.
• Official CNIPA invention filing fee: RMB 900, plus a RMB 2,500 substantive examination fee.

What Are the Three Types of Patents in China?

China recognizes three categories of patents, and choosing the right one shapes both your filing strategy and your protection. An invention patent covers new technical solutions to a product, process, or improvement and carries the strongest protection, with a 20-year term. A utility model patent protects the shape, structure, or combination of a product and is often described as a “mini-invention,” with a 10-year term and a faster, cheaper registration route. A design patent protects the external appearance, shape, pattern, or color of a product and now lasts 15 years following amendments to the Patent Law of the PRC.

The table below compares the three types side by side so you can see where each fits.

How Does the First-to-File Rule Affect Foreign Companies?

Under China’s first-to-file principle, patent rights go to the first applicant to file a valid application, not the first to invent. For a foreign company, the practical consequence is urgency: if a competitor, supplier, or even an employee files first, your claim to the technology can be lost or severely weakened. This is why experienced investors treat patent filings as part of their market-entry plan rather than an afterthought.

If you intend to manufacture through a Chinese partner or sell into the Chinese market, filing in China should be timed alongside your home-jurisdiction filing. A priority claim under the Paris Convention lets you file in China within 12 months of an earlier overseas filing while preserving the original priority date — a window that can make the difference between securing and forfeiting your rights.

Can a Foreign Company File a Patent Directly in China?

In most cases, no. A foreign applicant with no residence or business address in mainland China must appoint a licensed Chinese patent agency to act on its behalf before the China National Intellectual Property Administration (CNIPA). This is a statutory requirement, not a formality, and it applies to invention, utility model, and design applications alike.

The agency prepares and files the application, responds to office actions, and manages the procedural requirements on your behalf. Because filings must generally be in Chinese, accurate translation of the claims and specification is essential — a poorly translated claim can narrow your protection or invite rejection. Many foreign companies pair their patent filings with a broader intellectual property services in China strategy that also covers trademark registration in China and copyright.

How Much Does It Cost to Register a Patent in China?

The official CNIPA government fees are relatively low, especially for utility model and design patents. As of 2026, the official filing fee for an invention patent is RMB 900, with a further RMB 2,500 substantive examination fee; utility model and design applications carry a lower official fee of RMB 500. Annual maintenance fees apply after grant and rise over the life of the patent.

Official fees, however, are only one part of the picture. The total cost of a Chinese patent is driven by professional drafting, translation, and agency representation, which vary with the complexity of the technology and the number of claims. Fee reductions of up to 85% are available for qualifying applicants, including small entities and individuals, so it is worth confirming eligibility before you budget. Given the sums at stake in protecting a product line, most foreign companies treat patent costs as a strategic investment rather than an expense to minimize.

Step-by-Step: How to Register a Patent in China

The application process follows a consistent sequence, with invention patents requiring one additional stage: substantive examination.

First, conduct a prior-art search to confirm the technology is novel. Second, prepare the specification, claims, abstract, and drawings, and translate them into Chinese. Third, file the application through a licensed agency with CNIPA. For invention patents, CNIPA publishes the application after 18 months and the applicant then requests substantive examination, typically within three years of filing. The examiner issues office actions, the applicant responds, and if the objections are resolved, CNIPA grants the patent and issues a certificate.

Utility model and design applications skip substantive examination and proceed through preliminary examination only, which is why they are granted in a matter of months.

Patent Priority Examination for Faster Grants

China offers a priority examination channel that can dramatically shorten the timeline for qualifying inventions. Under the Measures for the Administration of Patent Priority Examination, applications in strategic and emerging industries, energy conservation, environmental protection, and other qualifying fields may request expedited handling, in some cases reducing an invention patent to well under a year.

Eligibility is not automatic; you must demonstrate that the technology falls within the listed categories and that priority examination is warranted. For foreign companies racing to secure protection before a product launch, this channel can be a decisive advantage, and it is one of several developments we track in our 2026 update on China IP cases and enforcement.

Enforcing Patents in Guangzhou, Shenzhen, and Across China

A granted patent is only as strong as your willingness to enforce it. China has expanded its specialized intellectual property courts and shifted many first-instance IP disputes to local courts, which has generally accelerated resolution. For companies operating in South China, this means a patent registered and enforced through the courts in Guangzhou or Shenzhen can now be litigated more quickly than in the past.

Enforcement options include civil litigation for damages and injunctions, administrative complaints to the local IP office, and, for imported infringing goods, customs recordal and seizure. Whichever route you choose, documentation matters: keep clear records of invention, filing, and use, and monitor the market for copies. A dedicated copyright registration in China can complement patents by protecting related works such as software and technical manuals. Building your patent portfolio in step with your company registration is the surest way to defend the technology that underpins your China business.
