Geographical indications (GI) are signs used on goods - frequently food, wine, or spirits - that have a specific geographical origin and are said to possess qualities, reputation or characteristics that are essentially attributable to that place of origin. Given the quality associated with the product, proponents of GI protection argue that it is needed to avoid consumer confusion as well as to protect legitimate producers. Europe has the most extensive geographical indication protections in the world. These include Protected Designation of Origin (PDO), which covers agricultural products produced, processed and prepared in a given geographical area using recognized know-how; Protected Geographical Indication (PGI), which covers agricultural products linked to the geographical area; and Traditional Speciality Guaranteed (TSG), which highlights traditional character, either in the composition or means of production. 

The net effect of the European system is that hundreds of items enjoy special legal protection. What does this have to do with the TPP?
