(a) the composition of the trademark.

The laws of different countries have different provisions on the composition of trademarks. For example, in CIS countries, the elements of a trademark can be words, graphics, three-dimensional, combination or other forms. According to the American trademark law, any words, symbols or signs, or a combination of these things, can be used as elements of a trademark. Due to the increasingly fierce trademark competition, some foreign manufacturers try their best to be unconventional in trademark design in order to attract customers, and have launched odor trademarks and audio trademarks one after another. Electronic data trademark, transmission trademark, etc. In some countries, such as Romania, the trademark law stipulates this, such as color, product shape or its packaging, sound, etc. Can be used as an integral part of a legal trademark. However, most countries have not yet implemented legal protection for the above-mentioned forms of trademarks. China's Trademark Law stipulates that trademarks should be composed of words, graphics or their combinations, and other forms cannot be used as the constituent elements of Chinese trademarks.

(2) the distinctive features of the trademark.

The uniqueness or identifiability of a trademark is a remarkable feature. Whether it is words, graphics, or the combination of words and graphics, it must be novel in concept and unique in style, which is enough to distinguish it from other similar trademarks.

(3) the color of the trademark.

The color of a trademark is of great significance to a trademark. Color is not a legal constituent element of a trademark, and generally cannot be used as a constituent element of a trademark alone. However, color is a part of the whole trademark, and it is one of the important signs that distinguish a trademark from other businesses. If the color of a trademark needs to be changed after registration, it is regarded as a change of the trademark graphic and must be registered again. Because trademark color is of great significance to improve advertising efficiency, many well-known trademarks have specified colors when registering.

(4) Characters and graphics of trademarks. Some characters and graphics are prohibited from being used as trademarks. Different countries have different regulations on prohibiting trademarks, so we should pay attention to the differences.

Due to the different customs, social and cultural backgrounds of different countries, some trademarks that are commonly used in one country or deeply loved by consumers may not be suitable for use in other countries. In trademark design, it seems that an international norm has been formed, that is, in the choice of trademark words and graphics.
