According to DuPont, the European manufacturer allegedly was engaged in inappropriate export of high-value HFC blend refrigerants into the Asia-Pacific market. The infringement alleged by DuPont was primarily focused on the manufacturer exceeding the scope of its authorization to manufacture, market, and sell DuPont™ Suva® HFC-404A.
This is the second out-of-court settlement that DuPont has reached this year over HFC refrigerant blend patent infringement. An earlier settlement, announced in February, also involved a major fluorochemicals manufacturer.
“DuPont is committed to protecting its global patent for high-value HFC Suva® refrigerant blends, and will continue to investigate and take necessary action,” said Mark S. Baunchalk, global business manager – refrigerants, DuPont Fluoroproducts.
