The "other" in trademarks refers to non-subject and supplementary identification information, which is usually used to distinguish goods or services from other brands. This identification information can be colors, patterns, text, etc. Its main function is to increase the attractiveness and recognition of the trademark and help consumers find the goods or services they need faster in the market.

In some specific trademark designs, "other" can become a representative element of the brand. For example, the trademark of the food and beverage company Coca-Cola has an "other" red wavy line, and this design has become part of the brand image. In addition, some fashion brands will also use "other" elements in their trademarks to highlight the fashion and personalization of the brand.

However, "other" can also cause confusion and illegal use of trademarks. For example, a beer brand called "Portuguese Fresh Beer" was misappropriated by other breweries. These manufacturers' trademarks added the word "other" after the brand name in order to become a brand similar to Portuguese Fresh Beer. This behavior not only misleads consumers, but also infringes upon the trademark rights of Portuguese fresh beer.
