DuPont and Star file court action

DuPont and Star Refrigeration are filing legal action over alleged patent infringement against a major manufacturer.

DuPont and Star Refrigeration have announced that they have filed legal action in Spain alleging patent infringement against a major refrigerant manufacturer and its distributor.

Star Refrigeration owns patents in Spain covering R-422D and other non-ozone-depleting refrigerants broadly used to retrofit and service commercial refrigeration and building air conditioning equipment.

DuPont is the sole licensee of Star Refrigeration for these patents, and markets R-422D as DuPont ISCEON MO29. ISCEON MO29 is part of the DuPont ISCEON family of non-ozone-depleting retrofit refrigerants.

These refrigerants have become the leading choice in Europe to enable equipment owners to continue to operate equipment designed for HCFC-22 refrigerant despite the ban of virgin HCFC-22 for service in the European Union.

“DuPont and Star Refrigeration have secured evidence that we believe will support their allegation of patent infringement regarding certain retrofit refrigerants put on the market in Spain,” said Greg Rubin, global business manager – DuPont Refrigerants.

“We are pursuing strong action to stop any infringement of our intellectual property in the Spanish market. Enforcement of refrigerant IP rights provides customers the assurance of continued access to safe, high quality and lawfully sourced refrigerants from reliable and reputable suppliers.”

“DuPont is committed to protecting intellectual property for refrigerants such as DuPont ISCEON MO29,” added Rubin.

“The protection of intellectual property is critical to ensuring our continued investment in new technologies and products for the cooling marketplace.”
