1. A collective trademark refers to a sign registered in the name of a group, association or other organization for the exclusive use of members of the organization in commercial activities, so as to show the membership of users in the organization. In some countries, federations of some enterprises can also be registered as representatives, and sometimes government agencies leading these enterprises register on their behalf. The function of a collective trademark is to show users that the enterprises that use the trademark have the same characteristics. Enterprises that use collective trademarks have the right to use other special trademarks at the same time. 2. Characteristics of collective trademarks (1) Collective trademarks do not belong to a single natural person, legal person or other organization, that is, they belong to a community organization composed of multiple natural persons, legal persons or other organizations, which means that goods or services come from a collective organization, which can be a specific industrial and commercial organization such as a guild or a chamber of commerce or other collective organizations, and the providers of specific goods or services retreat behind the collective as members. It embodies the characteristics of "* *" and "* * *"; (2) A collective trademark is a collective right that is applied for registration in the name of a collective and owned by all its members, which is reflected in the application for registration of a collective trademark, that is, only a collective organization with legal personality can apply, because only a collective organization with legal personality can own the trademark right in the name of its collective independence; (3) Collective trademarks are reflected in the use of trademarks, that is, collective organizations usually do not use collective trademarks, but are used by members of the organization. Non-members of the organization cannot use it; Every member has equal right to use, and there is no subordinate relationship between members; At the same time, it is necessary to supervise the use of its collective members and deal with members who violate the rules of use; (4) Uniform rules should be formulated for the registration, use and management of collective trademarks, specifying in detail the rights, obligations and responsibilities of members, as well as the amount and use of management fees, and making them public. Collective members should abide by each other and accept public supervision; (5) When a collective trademark is infringed, it shall include the losses suffered by the members of the collective organization; (6) When a member withdraws from the collective, he can no longer use the collective trademark. When new members join, they can use collective trademarks because they have obtained membership. This membership relationship is non-transferable, and so is the right to use a trademark based on this identity relationship. (7) Geographical indications can be registered as collective trademarks. At the press conference on the registration of collective trademarks with geographical indications as collective trademarks, natural persons, legal persons or other organizations whose commodities meet the conditions for the use of geographical indications may request to join a group, association or other organization registered with geographical indications as collective trademarks, and the group, association or other organization will be accepted as a member according to its articles of association; Those who do not require to join the group, association or other organization that uses the geographical indication as a collective trademark may also use the geographical indication properly, and the group, association or other organization has no right to prohibit it.
