It's similar to French wines and cheese. News to me that we have this in the US but it totally makes sense. We have a few of these in the PNW, like Hermiston melons and Walla Walla onions.

It's a broader EU thing (named AOP - protected designation of origin) rather than French only, though you are right that France has plenty of those for wines and cheese. But it's also protecting Greek Feta, Italian Parma ham, Scottish Shetland Wool, etc
