By 1888, three versions of Coca-Cola – sold by three separate businesses – were on the market. A co-partnership had been formed on January 14, 1888, between Pemberton and four Atlanta businessmen: J.C. Mayfield, A.O. Murphey, C.O. Mullahy, and E.H. Bloodworth. Not codified by any signed document, a verbal statement given by Asa Candler years later asserted under testimony that he had acquired a stake in Pemberton's company as early as 1887.[20] John Pemberton declared that the name "Coca-Cola" belonged to his son, Charley, but the other two manufacturers could continue to use the formula.[21]
