- This article discusses the structure of a geographical indication (GI), that is the model behind the rules, ie European Union (EU) rules. In fact, this industrial property right is complex, but some options were taken under EU law—a model that corresponds to the legal functions of this right as well as to its legal nature. However, the structure has some flexibility.
