Service
Protect your inventions, designs, and innovations in the world's largest patent-filing jurisdiction. China receives more patent applications annually than any other country.
China's patent system offers three levels of protection. Design patents protect the appearance of a product — shape, pattern, color, or combination. They are the fastest to obtain (approximately 6 months) and most affordable ($500). Utility model patents protect the structure or functional design of a product, offering 10 years of protection with examination in about 12 months ($1,500). Invention patents provide the strongest protection, covering new technical solutions and processes, with a 20-year term, but require full substantive examination taking 2-3 years ($3,000 and up). We help you choose the right type based on what you're protecting and your budget.
If you have filed an international patent application under the Patent Cooperation Treaty (PCT), you must enter the national phase in China within 30 months of your priority date. We handle this process end to end: translating your application, adapting claims to meet CNIPA formatting requirements, and filing within the deadline. Missing the 30-month window means losing your priority rights in China permanently, so early engagement is critical.
Chinese patents require annual fee payments to remain in force. Missing a payment results in the patent lapsing. Our IP Guardian service includes automatic annual fee tracking and payment, so your patents remain active without you having to monitor deadlines.
