How are well-known trademarks protected in Vietnam?

As a contracting party of the Paris Convention, Vietnam is obligated to give special protection to well-known trademarks. A well-known trademark is a mark that has been continuously used for prestigious products/services so that it becomes widely known. Rights under a well-known trademark are established based on a decision on the recognition of a trademark as well-known to be issued by the Intellectual Property Office of Vietnam upon the owner’s request.
