The most representative ones are: the definition of trademarks made by the International Association for the Protection of Industrial Property (AIPPI) at the Berlin Congress: Trademarks are used to distinguish A mark of goods and services provided by an individual or a collective. The World Intellectual Property Organization has defined the following in its Model Law on Trademarks: A trademark is a mark that distinguishes the products or services of one enterprise from those of another enterprise. The French government stated in its Trademark Law that any tangible mark used to identify the products, articles or services of any enterprise may be regarded as a trademark. It can be seen from the above definition that the user of a trademark is the producer, manufacturer, processor, selector or operator of the goods or services designated by the trademark, not the consumer. The use of trademarks on goods is different from the decoration on product packaging. The former is used to distinguish the source of the goods and is exclusive; while the latter is used to beautify, decorate, explain and promote the goods.

It is not only a kind of intellectual property rights, a kind of mental work result, but also a part of industrial property rights. It is an intangible property of the enterprise.
