first of all, it depends on the existence of category trademarks. Sometimes, under the same name, different categories will have different effects, so no matter how good the name is, it must be supported by categories. For example, the "lasting" trademarks mentioned above, generally speaking, which categories are popular should be analyzed in combination with the current entrepreneurial environment, but food, clothing, housing and transportation will always be a mainstream choice. It is also favored in the transaction, and the price will naturally rise. Second, it depends on fame. Although the fit between name and category is very important, sometimes fame will also play a great role. Just looking at the name and category may not form any connection, nor do you see any commercial value. However, after the hit of the series, this word has become a well-known hot word, full of business opportunities. Some enterprises can also find inspiration and creativity from stars, hot words and so on, and trademarks can be very attractive. There is another situation, after long-term use to obtain a certain reputation of trademarks, which bear the reputation of the market and consumers, but also add a lot of value to trademarks. Third, it depends on whether the trademark is complete. According to the provisions of the Trademark Law, small categories can be selected in trademark registration, but in the application process, some small categories may be rejected. In the end, although the registration certificate was obtained, the scope of application was greatly reduced, and even the key small categories were not obtained. The value of such a trademark is greatly reduced. Therefore, the more categories of trademarks are covered, the higher the value is.
