According to DuPont, the European manufacturer was engaged in inappropriate export of high-value HFC blend refrigerants into the Asia-Pacific market. The infringement allegation by DuPont was primarily focused on the manufacturer exceeding the scope of its authorization to market and sell DuPont™ Suva® HFC 404A.
“DuPont is committed to protecting its global patent for Suva 404A and other high-value HCFC and HFC blends, and will continue to investigate and take necessary actions to that end,” said Mark S. Baunchalk, global business manager — refrigerants, for DuPont Fluoroproducts.
In 2001, the company announced it had initiated a patent stewardship program within its distribution network in the United States, Europe, Asia-Pacific, and Latin America, and notified the network of possible unauthorized importation, marketing, and sales distribution of refrigerant blends, R-401A, -401B, -402A, -402B, -404A, -407C, -408A, -409A, and -410A.
