A collective trademark refers to a sign registered in the name of a group, association or other organization for members of the organization to use in business activities to show the membership of users in the organization. A collective trademark is not a trademark of a single enterprise, but a trademark owned and used by members of an organization composed of multiple enterprises or individuals. Collective trademarks are used by members of the organization, and non-members of the organization may not use or transfer them. In order to adapt to the characteristics of "* * * possession" and "* * * use" of collective trademarks, unified rules should be formulated for their registration, use and management, and announced to the public, and collective members should abide by them under the supervision of the public.
