A utility model in China is a type of IP right that protects technical solutions related to the shape, structure, or combination of a product. For foreign applicants and associates unfamiliar with this system, utility models are often misunderstood. This post aims to clarify when a utility model is the right strategic choice—and when it’s not.
1. Differences Between Utility Models and Invention Patents
1.1 Subject Matter
- Invention Patent: Covers new technical solutions for products, methods, or their improvements (e.g., drug preparation processes or manufacturing methods).
- Utility Model: Limited to physical innovations, such as the shape or structure of a product (e.g., improved mechanical joints, new housing designs).
1.2 Inventive Step
- Inventions require prominent substantive features and significant technical progress.
- Utility models require a lower threshold—just substantive features and some progress over prior art. They focus more on practicality and applicability.
1.3 Examination Process
- Inventions undergo both preliminary and substantive examination.
- Utility models undergo only preliminary examination, making the process faster and simpler.
1.4 Examination Time
- Invention: Typically 15–18.5 months.
- Utility Model: Around 6–10 months.
1.5 Protection Term
- Invention: 20 years from the filing date.
- Utility Model: 10 years from the filing date.
2. Benefits of Utility Models
- Shorter Grant Time: Protection can be obtained in less than a year.
- Lower Costs: Both application and maintenance fees are significantly lower.
- Higher Grant Rate: Due to the absence of a full inventiveness examination.
- Stronger Stability in Some Cases: Narrower prior art search reduces invalidation risks.
- Confidentiality: Unlike invention patents, utility models are not published before grant.
- Dual Filing Strategy: File both invention and utility model for the same subject to gain immediate protection and long-term rights.
3. When to Choose a Utility Model
- The subject matter must be structural—not software logic or material compositions.
- FMCG and fast-moving tech sectors benefit from quick grant times.
- Startups or SMEs can leverage lower costs for broader protection.
- Use utility models for defensive purposes, especially for improvements not core to the product but valuable in the market.
- Delay examination of the invention patent through same-day filings, allowing strategic flexibility.
4. Other Considerations
- Preliminary Examination Is Not Just a Formality: The CNIPA still checks clarity, support, and technical substance.
- Inventiveness Standard: Utility models require “substantive features and progress,” a lower bar than invention patents.
- Enforceability: While damages for utility model infringement may be lower when losses are unquantifiable, Chinese courts do uphold them. Case in point: Gree v. Aux (2018) resulted in ~¥46 million awarded for utility model infringement.
Final Thought
Utility models in China are a practical, cost-effective solution for protecting structural innovations quickly. They work best for products with physical improvements and are a great tool for portfolio diversification, market entry, or budget-conscious IP strategies.
If you're unsure whether a utility model fits your case, it's always worth speaking with a Chinese patent professional to make an informed decision.
