And then another yogurt company decided to market a new brand of yogurt... by naming it... (drum roll please...) "Bulgaria"!
Of course the first company sued the second company. And then the Bulgarian embassy weighed in, supporting the second company, because it turned out that the first company was using yogurt-making germs imported from Germany!
And then the court decided for the first company, essentially declaring that the nation of Bulgaria, sadly, does not own the name "Bulgaria" (or "Bulgaris", or Bulga-whatever) in Korean trademark system. (But don't quote me on that. IANAL.) The whole affair was very entertaining.
