(1) If the symbolic elements that constitute a trademark are self-created words or phrases without meaning, or are in the form of animal cartoons or expressed through special techniques, they are strong trademarks, such as when used in "refrigerator" "Haier" trademark on "Color Film" and "KODAK" on "Color Film". The inherent distinctiveness of a trademark is not only reflected in the content of its symbolic elements, but also in the form of expression of its symbolic elements. Taking a word trademark as an example, its inherent distinctiveness is not only reflected in the combination of words, but also in its form of expression, that is, fonts or combinations that contain certain design elements, such as special fonts, handwriting (including signatures), etc. Generally speaking, the stronger the inherent distinctiveness of a trademark, the greater the possibility of obtaining special protection.

(2) If the symbolic elements that constitute a trademark are ordinary words or phrases with meaning, or are common graphics on certain types of goods, or are common forms of animals in nature, it is a weak trademark. For example, if it is used on The "Great Wall" trademark is used on "wine" and the "Grassland" trademark is used on "wine".

(3) If a trademark consists of symbols that are not distinctive, it is not considered a trademark, but is just a symbol.
