A collective trademark is a trademark owned by several different owners and is called a collective trademark. 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. Collective trademarks are generally not allowed to be transferred. China, the United States, most western civil law countries, some eastern European countries and some developing countries all have provisions to give collective trademark registration protection.
