Global: Daikin Expands Patent Non-Assertion Pledge for Equipment Using Low GWP Refrigerant HFC-32

July 1st, 2021

Company to facilitate industry adoption of HFC-32 with pledge of free access to approximately 300 patents

Daikin Industries, Ltd. ("Daikin") has added 123 new patents to its Pledge which includes a grant of free access to its pledged patents in relation to certain HVAC-R (heating, ventilation, air conditioning, and refrigeration) equipment using the non-blended, single-component refrigerant HFC-32 (R-32). Approximately 300 patents are now free to use and do not require permission or a written contract with Daikin. As a result, the company will facilitate the further adoption of HFC-32, which has a lower global warming impact than many refrigerants commonly used today.
