I heard from a Xango booth this weekend and the guy with whom I spoke said that Xango a patent, so that no other place in the world with a mangosteen beverage manufacture of the shell may have. The fact that only the inner fruit is legally for sale in other brands. That does not sound right. How can something that the patent is, of course? It is as if one has a patent on banana peels. No one can banana skins or be sued!
