DuPont and Star Refrigeration Glasgow, UK, announced that they have filed legal action in Italy alleging R-422D patent infringement against a major refrigerant reseller.

Star Refrigeration owns patents in Italy covering R-422D, a non-ozone-depleting refrigerant 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 our allegation of patent infringement in Italy regarding the R-422D refrigerant,” said Diane Iuliano Picho, global business manager – DuPont Refrigerants.  “We are pursuing strong action to stop illegal trade of R-422D in the European market. Enforcement of refrigerant intellectual property rights provides customers the assurance of continued access to high quality and lawfully sourced refrigerant from reliable and reputable suppliers.”

“DuPont is committed to protection of intellectual property for refrigerants – these efforts are critical to ensuring our continued investment in new technologies and products for the cooling marketplace,” Picho added.

DuPont Refrigerants is a leading global supplier of products and technologies with more than 80 years of leadership and commitment to developing more sustainable products for the air conditioning and refrigeration industry. Using science and technology, market knowledge and global reach, DuPont provides sustainable materials and solutions that enhance personal comfort, enable food preservation, improve industrial processing and reduce environmental footprints.
