After Candler had gained a better foothold on Coca-Cola in April 1888, he nevertheless was forced to sell the beverage he produced with the recipe he had under the names "Yum Yum" and "Koke". This was while Charley Pemberton was selling the elixir, although a cruder mixture, under the name "Coca-Cola", all with his father's blessing. After both names failed to catch on for Candler, by the middle of 1888, the Atlanta pharmacist was quite anxious to establish a firmer legal claim to Coca-Cola, and hoped he could force his two competitors, Walker and Dozier, completely out of the business, as well.[1]
