Chemours Files Second Lawsuit Against AGC, Inc. for Infringement of HFO-1234yf Patent

WILMINGTON,Del.,Nov. 22,2021 -- On November 12,2021,The Chemours Company (Chemours) (NYSE: CC),a global chemistry company with leading market positions in Titanium Technologies,Thermal & Specialized Solutions,Advanced Performance Materials and Chemical Solutions,announced that it files a second patent infringement lawsuit in Japan against AGC,Inc.This action reaffirms Chemours' commitment to vigorously defend its intellectual property and investment in Opteon™ low global warming potential (GWP) refrigerants and builds on its on-going efforts to stop the unlicensed manufacture,marketing,and sales of Opteon™ HFO-1234yf (R-1234yf) refrigerant by all legal means wherever that activity occurs around the world.

The second lawsuit was filed on November 12,2021 with the Tokyo District Court Civil Divisio (case number 2021(Wa)29388). It alleges infringement of Chemours' patents covering HFO-1234yf product compositions. This is a great example of Chemours' using its international patent estate in order to protect its investment in the development and commercialization of HFO-1234yf and to ensure that customers obtain authentic refrigerant.

Chemours offers a full portfolio of low GWP HFO solutions under the Opteon™ brand that delivers the optimal balance of performance,safety,sustainability and total cost of ownership to meet the long-term needs of the commercial refrigeration,air conditioning,heat pump,and chiller markets. They have been developed to help meet increasingly stringent global regulations while maintaining or improving performance compared to the products they replace,as well as encouraging more sustainable refrigerant choices and equipment designs to reduce the carbon footprint of the HVACR industry.
