However, if you want to apply for a three-dimensional trademark, you must register the non-note clause of the three-dimensional trademark: it must not be determined by the nature of the commodity, it must not be necessary to achieve a certain technical effect, and it must not be given substantial value.
In the past, there were no three-dimensional trademarks in China for fear of conflicts with other rights, especially appearance patents, so there were such strict restrictions.
If you have any other questions, you can leave a message at any time.
