HFC-32 has many advantages that can help reduce the environmental impact of air-conditioning and heat pump equipment. HFC-32 is a non-ozone depleting refrigerant with a global warming potential (GWP) one-third of that of current R-410A refrigerant. It also provides excellent system performance and is readily available. As a single-component refrigerant, it is easy to recover, recycle, and reclaim, which helps reduce the need for additional production of refrigerant. Therefore, Daikin believes HFC-32 is suitable refrigerant to reduce environmental impact in many regions.
By providing free access to the pledged patents, all of which have been filed after 2011, Daikin looks to further facilitate the adoption of HFC-32 equipment. Free access to the pledged patents is provided without requiring pre-approval from Daikin. It requires no contracts, as are typically required for patent licensing programs. This eliminates complicated processes and provides quick and easy access to the pledged patents.
Once listed, a pledged patent will not be removed, and the Pledge will not be withdrawn against a party unless that party triggers Daikin’s right of defensive termination by, for example, filing a lawsuit or other legal proceeding alleging patent infringement against single-component HFC-32 equipment provided by Daikin or one of its group companies.
