Introduction

Design patents play a crucial role in protecting the aesthetic aspects of products, providing innovators with exclusive rights to their visual creations. In China, design patents are a significant part of the intellectual property landscape, offering protection to the ornamental designs of products. This article explores the subject matter eligible for design patent protection in China, outlining the criteria and scope of what can be patented.

Definition and Scope of Design Patents in China

According to the Chinese Patent Law, a design patent protects the "shape, pattern, or combination thereof, or the combination of color with shape and pattern, of an overall or partial product which is rich in aesthetic appeal and is fit for industrial application." This definition encompasses several key elements:

1. Shape: The three-dimensional configuration of a product.
2. Pattern: The two-dimensional decoration or design on the surface of a product.
3. Color: The color scheme applied to the shape or pattern of a product.
4. Combination: Any combination of the above elements.

The design must be new, meaning it should not have been disclosed in publications in China or abroad, nor should it have been publicly used or known before the filing date of the patent application.

Criteria for Design Patent Protection

According to Article 23 of Chinese Patent Law, to qualify for design patent protection in China, a design must meet the following criteria:

Any design for which patent right may be granted shall not belong to a prior design, nor has any entity or individual previously filed before the date of filing with the Patent Administration Department under the State Council an application relating to an identical design that was presented in patent documents published after the said date of filing.

The design for which a patent right may be granted shall be substantially different from prior designs or a combination of the features of prior designs.

Any design for which a patent right may be granted must not be in conflict with any prior legal rights obtained by any other person before the date of filing.

Exclusions from Design Patent Protection

Certain subject matters are excluded from design patent protection in China. These include:

1. Designs that violate laws or social morality: Any design that contravenes Chinese laws or is considered detrimental to public order or good morals is not eligible for protection.
2. Two dimensional designs of images, colors or combinations of the two that mainly serve as indicators.
3. Designs that are identical or similar to the national flag, national emblem, or other state symbols: Such designs are excluded to maintain national dignity and respect.

Application Process for Design Patents in China

The application process for obtaining a design patent in China involves several steps:

1. Preparation of Application Documents: These include a request form, drawings or photographs of the design, a brief description of the design, and any necessary priority documents.
2. Submission to the China National Intellectual Property Administration (CNIPA): The application is submitted to the CNIPA, which conducts a preliminary examination to ensure all formal requirements are met.
3. Publication and Grant: If the application passes the preliminary examination, it will be published, and the design patent right will be granted.

Enforcement and Protection

Once granted, a design patent in China provides the patent holder with exclusive rights to use the design and prevent others from using it without permission. Enforcement can be pursued through administrative actions, civil litigation, or customs protection measures.
