Geographical indications and trademarks: between conflict and coexistence
Geographical indications (GIs) protect the name of a product originating from a specific geographical area and which owes its qualities or reputation to its origin. It is common for trademarks to include terms that are identical or evocative of a GI or, conversely, for a GI to include terms found in earlier trademarks, which can give rise to conflicts.
