In late September 2026, the China National Intellectual Property Administration (CNIPA) revoked the practice licenses of six Chinese patent agencies at once under the Patent Agency Regulations. The takeaway: an agency that looks perfectly "legitimate" on the surface can lose its license overnight — and drag your application and your enforcement rights into serious trouble.
Why choosing the right agency matters
China operates a "first-to-file" system with substantive examination, and the quality of the drafted application largely determines the grant rate, scope of protection, and stability in litigation. An inexperienced agency may omit key technical features, claim too narrow a scope, or mishandle office actions — leaving your patent easy to design around or invalidate after grant.
Equally important, holding a practice license issued by CNIPA is the basic threshold for lawful practice. Enforcement has visibly tightened in 2026, and problems such as unlicensed agencies, low-price baiting, and sub-contracted drafting are being cleaned up in waves.
Method 1: Verify the license on CNIPA's official website (most authoritative)
Step 1: Go to CNIPA's Patent Agency Management System at http://dlgl.cnipa.gov.cn (or the "National Patent & Trademark Agency Public Service Platform" mobile app).
Step 2: Enter the agency name and confirm it holds a patent agency practice license and is in "normal operation" status. This is the most authoritative and reliable verification.
Step 3: Check the number and registration status of the agency's registered patent agents, to make sure your case is actually drafted by a licensed agent — not taken in by a salesperson and sub-contracted out.
Step 4: In CNIPA's service hall, open the "Patent Agency Annual Report Query" to review the firm's annual report and workload figures.
Tip: CNIPA also continuously publishes lists of companies operating as "IP agencies" or "patent agencies" without a practice license (the latest batch was published in June 2026). Always check first — don't be swayed by names like "International IP Company" or "XX Patent Agency Group."
Method 2: Check the agency's annual filing volume
Step 1: Log in to CNIPA's Patent Business Processing System (https://cponline.cnipa.gov.cn) or the China and Multi-Country Patent Examination Information Inquiry (https://cpquery.cnipa.gov.cn).
Step 2: Search by "agency" and count that firm's patent filing volume and grant volume in China over the past 1–3 years.
Step 3: Cross-check with the Patent Agency Annual Report to verify the firm's scale, number of registered agents, and yearly volume against public data.
Filing volume is the most direct indicator of an agency's strength and experience. Top firms file thousands to tens of thousands of cases a year, which means their drafting templates, examination experience, and workflow management have been tested in practice. For invention patents, prioritize firms with deep experience, strong grant rates, and high volume in your field. For utility models and designs you can be more flexible, but stay wary of "low price + zero track record" offers.
Method 3: Follow what the big players use
Step 1: In a Chinese patent search system (e.g., CNIPA's patent search & analysis platform, sopac.cnipa.gov.cn), search by applicant for industry leaders such as Huawei, Tencent, Xiaomi, or Gree — or recognized companies in your own field.
Step 2: Look at the agency column on those patents and identify the firms that appear repeatedly and consistently.
Step 3: Agencies retained by big companies over the long term have typically passed strict vendor screening for drafting quality, workflow management, and confidentiality — a strong vote of confidence you can rely on.
But "what big companies use" isn't the whole story: big players usually have their own disclosure standards and stronger bargaining power. SMEs and individuals should weigh license + case volume + big-brand endorsements + field fit together.
Bonus: 4 red flags to avoid
Verify the agent's credentials: Confirm the drafter holds patent agent registration and is willing to be named. Be wary of agencies that "sell" the case and sub-contract the drafting.
Beware of unrealistically low prices: Quotes far below market rates (invention attorney fees of just a few thousand CNY or less) often come with poor drafting or hidden follow-up charges.
Check field fit: Mechanical, chemical, biopharma, and software/telecom cases require very different drafting logic. Choose a firm with expertise in your technology area.
Check for red flags: Use China's National Enterprise Credit Information Publicity System to check the firm and its shareholders for abnormal operations or serious dishonesty records.
China patent FAQ
Q1: How long does it take to get a patent granted in China?
Invention: generally about 2–3 years (CNIPA's official reply: inventions typically grant in around 3 years under qualifying conditions, and over 2 years in many cases). With prioritized examination you can speed this up — inventions must be concluded within 1 year from the prioritized examination notice. Some provinces/cities also offer a fast-track "preliminary examination" channel.
Utility model: generally 0.5–1.5 years to grant.
Design: generally about 0.5 years to grant.
Actual time depends on technical complexity and examination progress, and varies significantly by field.
Q2: How much does a Chinese patent application cost?
Official fees (current schedule):
| Type | Filing fee | Substantive exam fee | Annuity (years 1–3, per year) |
|---|---|---|---|
| Invention | CNY 900 + CNY 50 publication fee | CNY 2,500 | CNY 900 |
| Utility model | CNY 500 | — | CNY 600 |
| Design | CNY 500 | — | CNY 600 |
Eligible individuals and small companies can apply for a fee reduction of up to 85%.
Attorney service fees (market rates, vary by firm and complexity): invention from a few thousand to CNY 20,000–30,000; utility model roughly CNY 1,500–4,000; design roughly CNY 800–2,000.
Q3: How long does patent protection last in China?
Under Article 42 of the current Patent Law: invention patents 20 years, utility model patents 10 years, design patents 15 years, all counted from the filing date. In certain cases, invention patents may also receive patent term adjustment. Annuities must be paid on time during the term — late payment can cause the right to lapse.
Q4: How long does it take to get a grant after a PCT application enters China?
A PCT application must enter the Chinese national phase within 30 months from the priority date. After entry, it proceeds through substantive examination like a normal invention application, so the grant timeline is similar to a regular invention (generally 2–3 years). To accelerate, you can request prioritized examination after entry (inventions concluded within 1 year).
Important: This article is general information, not legal advice. Always confirm the latest official fee schedule with CNIPA, verify the agency's license through the Patent Agency Management System, and sign a formal agency agreement before proceeding.
