Article 8 of China's current Trademark Law stipulates: "Any sign that can distinguish the goods of natural persons, legal persons or other organizations from the goods of others, including words, graphics, letters, numbers, three-dimensional signs, color combinations and sounds, and the combination of the above elements, can apply for registration as a trademark." The type and scope of protection of non-traditional trademarks in this article are not clear enough, which is controversial. From the legislative point of view. From a judicial point of view. From a management point of view.
