Answer A three-dimensional trademark is also called a three-dimensional trademark. It is different from the trademark pattern that we usually see on a flat surface. Instead, it appears in a three-dimensional material form with three dimensions: length, width, and height. This form may appear on the appearance of the product, or on the container or other places of the product. The addition of regulations for the registration and protection of three-dimensional trademarks is a new addition to the newly revised Trademark Law in 2001, which will make my country's trademark protection system more complete. Not all three-dimensional marks can be registered as trademarks. Article 12 of the Trademark Law stipulates: “When applying for a registered trademark with a three-dimensional mark, a shape that is solely caused by the nature of the goods themselves, a shape of the goods that is necessary to obtain technical effects, or a shape that makes the goods of substantial value shall not be used. "Registered as a trademark." It can be concluded that the following three-dimensional mark shapes cannot be registered as trademarks: 1. Shapes generated only by the nature of the goods themselves, such as book shapes, general light bulb shapes, etc.; 2. For obtaining The shape of the product necessary for technical effects or the shape that makes the product have substantial value, such as the shape of a razor, the shape of a kitchen knife, etc.; 3. The shape that makes the product have substantial value, such as the shape of a tire, etc.
