The aim of this comparative study is to analyse and compare the systems in force in nine Latin American countries in terms of protection systems linked to the valorisation of origin, know-how, production processes and traditional knowledge applied to production processes, whether through the GI/DO system or other protection systems that distinguish and valorise locally produced products/services through collective distinctive signs. To this end, work has been carried out with national experts from the selected countries, based on questionnaires drawn up by the authors according to the needs of the research, and subsequent exchanges of information and specific consultations. The information provided by the national experts includes current regulations, jurisprudence and concrete cases that exemplify the functioning of the respective national systems.
