In 1993 the Kona Coffee Council, a regional coffee growers association, tried unsuccessfully to protect the name "Kona Coffee" by trademarking their logo with the United States Patent and Trademark Office. They were opposed by Kona Kai Farms, Inc, Captain Cook Coffee Co., Hawaiian Isles Enterprises, and Hawaii Coffee Company. In 2000 the Department of Agriculture of the State of Hawaii registered a "100% Kona Coffee" certification mark with the U.S. Patent and Trademark Office. Administration in regard to this certification mark was handed over by the State Department of Agriculture to the Hawaii Coffee Company, part of Topa Equities Ltd, based in Los Angeles.
