The PepsiCo owned juice maker Tropican has been dealt a blow by the US Patent Office after it moved to revoke a patent that gave Tropicana a significant competitive advantage. US Patent office ruled that technology used to blend several types of oranges is not exclusive to the company. The technology, in effect required growers of certain varieties of early-season juice to sell crops only to Tropicana, allowing Tropicana to produce Not From Concentrate (NFC) juice from fresh fruit about two months earlier than its competitors.
