A spokesman for Minute Maid, the Coca-Cola-owned fruit juice brand, has refuted claims made by consumer goods group, Procter & Gamble (P&G), that it is using a process for fortifying its orange juice for which P&G owns the patent. P&G alleged in a lawsuit, filed in May, that Minute Maid is infringing on P&G's FruitCal technology, a method of adding calcium to juice, in the production of at least two types of orange juice. P&G registered its patent for this technology in 1988.
