Advertising language has obvious characteristics, which have two requirements. First, it is easy to understand that words or expressions commonly used in business activities cannot be used. Second, advertising language is not easy to be too long, and it is easy to be identified as lacking in distinctive features. The more words, the easier it is to be recognized as a common advertising language. Simplicity itself is one of the basic characteristics of symbols. In addition, when an advertising language has been associated with a specific commodity or service for a long time and has undergone a lot of advertising activities, and the advertising language has established a unique corresponding relationship with its commodity or service among consumers, it can be registered.
