yes, if the product can be confused and the name is close enough. For example, you can no longer sell german cheese called "Parmesan", because it can be confus

yes, if the product can be confused and the name is close enough. For example, you can no longer sell german cheese called "Parmesan", because it can be confused with Parmigiano. Likewise, the italian wine called Tocai is no longer produced under this name, because it could be confused with the hungarian Tokaji, even tho they're quite different. It is literally to fight the issue raised by OP. If the product is very different than yeah, it would make no sense, but I do not know what dutch Parmaham is supposed to be. If it's not trying to bank on the notoriety of Prosciutto di Parma, I do not understand why it's not called Amsterdham, which would be a really cool name.
