What Can a China Design Patent Protect?
A China design patent protects the visual appearance of a product rather than its technical function.

Product Technologies
Equipment, components and their interaction may form the focus of an application. We help explain their technical features, operation and intended benefits.

Manufacturing Methods and Processes
We organize processing steps, production sequences and operating conditions to identify the technical details that the application needs to explain.

Systems and Control Technologies
For sensing, control or coordinated systems, we assess the actual technical solution and its supporting details to determine the application focus.

Technical Improvements
We examine changes to performance, operation or processing, using the technical record and initial search to describe the improvement in the application.

China Design Patent FAQs
A few practical things overseas applicants often want to know before filing.
Eligible products, methods and technical improvements may qualify, including equipment technologies, manufacturing processes and control methods. Suitability depends on the actual technical content.
The usual priority period is 12 months from a qualifying first foreign invention or utility model filing. PCT applications and missed deadlines require a separate review.
We need to review what was disclosed, when and how, including any applicable statutory exceptions. Please provide publication, sale or exhibition records.
Provide applicant and inventor details, technical descriptions, drawings, operating steps and differences from existing technology, together with earlier filing and disclosure records.
Yes. An initial search helps identify relevant prior art and informs application preparation. We agree the scope and fees before starting.
For non-PCT invention applications we handle, routine examination responses and necessary amendments are included in the agreed professional fee. Official fees are additional. PCT entry, translation and responses are quoted separately; additional work is agreed separately.
Timing depends on the technology, documents, examination schedule and response process. We explain the preparation plan and report actual progress as official actions arrive.
The standard invention patent term is 20 years from filing; any applicable term adjustment requires separate review. Annual fees are required after grant, with monitoring and payment services available by agreement.
