a visual trademark consisting of three-dimensional elements, also known as a shape trademark. The protection of three-dimensional trademarks has been controversial until the signing of TRIPS Agreement. As a three-dimensional mark, a three-dimensional trademark often has stronger visual impact than a flat trademark and can identify the source of goods or services better. However, because some countries are worried that the protection of a three-dimensional trademark may conflict with the protection of copyright, patents, especially design patents, it will not be protected for a long time. At present, countries that protect three-dimensional trademarks generally attach strict restrictions when registering three-dimensional trademarks. For example, the three-dimensional mark must not be determined by the nature of the goods, must not be necessary to achieve a certain technical effect, and must not be given substantial value to the goods.

Materials to be submitted in the application for a three-dimensional trademark:

An Application for Trademark Registration, signed or sealed by the applicant;

a power of attorney for trademark, signed or sealed by the applicant;
