TBILISI (AFP) - Georgia is trying to win back the trademark for Soviet leader Joseph Stalin's favourite brand of red wine in the United States, officials said on Friday. Georgia's patent office said that it was in negotiations with US-based company Dozortsev and Sons, which it said currently has the exclusive right to sell the semi-sweet Georgian wine called Khvanchkara in the United States. "A monopoly for Georgian wines' trademarks in one private company's hands may damage the interests of our winemakers," the head of the patent office, Irakli Gvaladze, told AFP.
