The firm’s Switzerland-based operations said it had taken joint action with Star Refrigeration Glasgow, UK, over non-ozone depleting R-422D - a trademarked refrigerant which is marketed to DuPont as ISCLEON MO29.
DuPont said it is the sole licensee under a Star Refrigeration patent covering the products used to retrofit and service commercial refrigeration and building air conditioning equipment.
“DuPont is committed to protect intellectual property for refrigerants such as DuPont ISCEON MO29,” said Diane Iuliano Picho, global business refrigerant manager. “The protection of intellectual property is critical to ensuring our continued investment in new technologies and products for the cooling marketplace.”
The company told FoodProductionDaily.com it was unable to give any further details under the terms of the legal deal reached with the reseller in Italy.
