Answer: unluckily or not, almost everything. If the name is not registered somewhere, the use of name is legal in whatever country. If the contents are known and not registered somewhere, then its reproduction is legal there where there is no contestation. Even if it would be impossible to sell a counterfeit of Chanel under Chanel in France, for example, it is perfectly possible to conceive some chanel 5 be sold under the name of ‘Pompadour’ without further claim inside of France, as contents not necessarily duely registered. To say: in order to avoid a counterfeit you register a Chanel 5 with contents that are not exactly corresponding to reality. If someone does register another perfume with the real contents and another name, he’s legally selling real Chanel 5 … in France.
