Graphical User Interface (GUI) is a way of displaying function keys and functional components of equipment, facilitating interaction between humans and the equipment. Since GUI was first introduced in 2014 into the China legal framework as an eligible subject matter for design patents, notable changes have occurred, offering IP owners more possibilities and options for enhanced GUI design protection in China. In this article, we will explore regulatory changes, filing trends, and the practice of GUI design patents.
Regulatory changes
The rules for GUI design patents in China were marked by the following key milestones on the regulatory timeline. Essentially, the regulatory restrictions on GUI design patents in China have been loosened over time.
Filing trend
In parallel with the loosening regulations, the filings of GUI design patents are growing strongly in China (see below chart).

Remarkably, GUI design patents filed under the category of “screen displays and icons” (Locarno design classification 14-04) increased fourfold from 2014 to 2022. A large portion of these design patents has been filed by Chinese applicants, although remain underutilized by international applicants. According to our research, less than 3% of Chinese GUI patents published in 2021 to 2023 were filed by international applicants.
Despite this trend, we anticipate that international companies may increasingly recognize the value of protecting their innovative GUI designs in China.
What GUIs can be protected by design patents in China?
We’ve analysed the subjects of registered GUI designs in China filed from 2014 to 2023 and observed a shift from GUIs bonded with hardware to GUIs independent of hardware. The chart below illustrates how the top subjects for GUI designs change over time.

We’ve also observed that Chinese GUI design patents are extended from traditional GUIs on computer or mobile phone screens to non-traditional GUIs such as automotive HUD (Head-Up Displays), VR/AR/XR displays, and GUIs related to virtual characters.
Moreover, Chinese design patents on parts or components of GUIs in the form of partial designs have become possible since 2021. Typical subjects for GUI design patents in China include the following:
GUIs independent of hardware
GUIs bonded with hardware
Parts or components of GUIs
What GUI/GUI elements cannot be protected by design patents in China
There are also limitations to the patent eligible subjects of GUI design patents. The Guidelines for Patent Examination (Section 7.4, Chapter 3 of Part I) explicitly excluded the following subjects from design protection in China:
It is worth nothing that for an icon in a GUI, if it is just a pattern displayed by a display device unrelated to human-machine interaction, the icon may not be protectable by a Chinese design patent. However, if it is an icon for user-interaction, e.g., launching an APP on an electronic device, it may be considered to be relevant to human-machine interaction and protectable.
Patent Practice
GUI designs will follow the general requirements for a design patent from filing to grant.
Priority
A Chinese design patent may be filed based on a foreign or domestic priority within 6 months from the application date of the first filing. The first filing may be design, patent, or utility model application(s).
Formality requirement
Partial Design
Examination
A design patent will be subject to formal examination before granting. Examination of obvious differences over prior designs has been introduced as a part of formal examination in the Guidelines for Patent Examination in 2024. This means there is a higher bar for the granting and validity of design patents in China.
Grant
On average, a Chinese design patent may be granted within 3–4 months under the current practice. The examination of GUI design patents may take longer. According to our research, the average pendency from filing to granting is around 7-8 months for GUI design patents filed in 2021 to 2023.
General Recommendations
In summary, as the rules of the game have been changed significantly, we would advise IP owners to explore and utilize the possibilities of improved GUI design patent protection in China.
