Can only speak for myself, but as there is no really objective way to measure that kind of equivalence, we as consumers are left with the rather blunt tools of traditions and establishing brands when it comes to food. Some of the product types which are protected are several hundred years old, predating all trademark laws which would otherwise have had a similar effect.

There are also some products in EU which are sold as '<something something> style <fooditem> because of the reason you state, but with that said: They rarely reach the quality of the 'real deal'. Apparently it is not very easy to create similar quality products?
