Types of Patents in China
China offers three types of patents: invention patents, utility model patents, and design patents. Each type serves a different purpose and offers varying levels of protection.
Invention patents provide the most comprehensive protection, covering new technical solutions or improvements to products and processes. These patents undergo substantive examination to assess novelty, inventiveness, and industrial applicability.
Utility model patents are similar to invention patents but are granted for new technical solutions related to the shape or structure of a product. They offer a quicker and less expensive route to protection, as they do not require substantive examination. However, they provide a shorter protection term compared to invention patents.
Design patents protect new designs of the shape, pattern, or combination thereof, which are aesthetically appealing and fit for industrial application. These patents focus on the visual aspects of a product and do not undergo substantive examination.
Understanding the differences between these patent types is crucial for selecting the appropriate protection for your innovation. For instance, if you have developed a novel manufacturing process, an invention patent would be suitable. If your innovation involves a new product design, a design patent would be more appropriate.

For example, a global tech company with an innovative software solution might opt for the PCT route to secure international protection and later enter the national phase in China based on commercial priorities and market potential.
Submitting the Application
Once you have chosen the appropriate filing route, the next step is to submit the application to the CNIPA. The application should include the patent specification, claims, abstract, and any necessary drawings. Additionally, you need to submit a request for substantive examination for invention patents or a request for formality examination for utility model and design patents.
The CNIPA requires that all documents be submitted in Chinese. If your original documents are in another language, you must provide accurate translations. It is advisable to work with a professional translation service to ensure that the technical and legal nuances of your application are accurately conveyed.
Upon submission, the CNIPA will issue a filing receipt, confirming the filing date and application number. This filing date is crucial as it establishes the priority date for your patent application, determining the timeline for subsequent procedures and deadlines.
Examination and Prosecution
Substantive Examination
For invention patents, the CNIPA conducts a substantive examination to assess the patentability of the invention. This examination involves evaluating the novelty, inventiveness, and industrial applicability of the invention based on the prior art identified during the search phase.
During substantive examination, the CNIPA may issue office actions, requesting additional information, amendments, or clarifications. It is essential to respond promptly and thoroughly to these office actions to address any concerns and advance the prosecution of your application.
For example, if the CNIPA raises objections regarding the inventiveness of your invention, you can provide detailed arguments and evidence to demonstrate why your invention is not obvious in light of the prior art. Engaging with experienced patent attorneys can help you navigate this process effectively and increase the chances of obtaining a granted patent.
Accelerated Examination Options
The CNIPA offers accelerated examination options for applicants seeking expedited processing of their patent applications. The Patent Prosecution Highway (PPH) program, for instance, allows applicants to leverage favorable examination results from other participating patent offices to expedite the examination process in China.
By participating in the PPH program, you can benefit from faster examination and potentially reduce the time and costs associated with patent prosecution. This option is particularly useful for applicants who have already secured patents for the same invention in other jurisdictions and wish to streamline the process in China.
For example, if you have obtained a granted patent for your invention in the United States, you can request accelerated examination in China through the PPH program, using the U.S. patent as a basis for fast-tracking the examination process.
