How to File a Utility Model in China (CNIPA)

A Chinese utility model (实用新型, shíyòng xīnxíng) is one of the most strategically important IP tools available to any inventor manufacturing in or selling to China. It registers in 6–12 months without substantive examination and provides 10 years of enforceable protection. For inventors working with Chinese manufacturers, a utility model should be filed before sharing any design files.

How to File

1. Instruct a registered Chinese patent agent (foreign applicants cannot file directly)
2. Provide a specification, claims, drawings, and abstract (Chinese translation required)
3. The agent files at CNIPA
4. Government fees: approximately RMB 500 (USD $70)
5. CNIPA conducts formal examination only (no prior art search, no inventive step assessment)
6. Registration typically in 6–12 months

What It Costs

Government filing fees are minimal — roughly RMB 500 (about $70). The real cost is professional services. A local Chinese agent handling a straightforward translation-and-file job may charge $1,500–$3,000 total. However, a full-service patent attorney who drafts the specification and claims from scratch, manages the Chinese translation, advises on claim strategy, and handles CNIPA correspondence typically charges $5,000–$8,000. If you are using the dual-filing strategy (utility model + invention patent from the same specification), expect the combined cost to sit at the higher end of that range or above. Budget realistically — the $1,500 figure you may see quoted online reflects a bare-minimum scenario that rarely matches what a foreign inventor actually pays.

What It Covers

Products and devices only — NOT processes or methods. The claims must describe a physical structure (shape, construction, or combination). Software-only inventions and chemical compositions are not eligible for utility model protection.

The Dual-Filing Strategy

File both a Chinese invention patent (full examination, 20 years) and a utility model (registration, 10 years) from the same specification. The utility model registers first, providing immediate enforceable rights — while the invention patent undergoes 2–4 years of substantive examination. Under China's dual-filing system, if both are granted, the applicant must abandon one when the invention patent grants (choose to keep the invention patent for its longer term and examined status).

Enforcement Value

Chinese utility models are enforceable in Chinese courts and through platform mechanisms (Alibaba AIPP, JD.com). A CNIPA evaluation report (patentability assessment obtained after registration) significantly strengthens enforcement — request one before initiating enforcement actions.
