Divided from the way and scope of registered trademarks, there are mainly two types of joint trademarks and defensive trademarks:
Joint trademark
Union means that the owner of the same trademark applies for registration of two or more similar trademarks on the same or similar goods, one of which is designated as a main mark or a positive mark, and the rest is a joint mark.

The use of a joint trademark expands the scope of the exclusive right to use a registered trademark, which helps to prevent the trademark of another person from being similar to the trademark of one's own and is mistaken by consumers in the market. Such as: Hangzhou Wahaha Group Co., Ltd. not only applied for the "Wahaha" trademark, also applied for "doll", "hahava", "baby doll", but also one after another in the relevant product categories registered "Wahaha" and its siblings trademark.
