 In October 2018, Microsoft released 60,000 patents to the Open Invention Network members for Linux systems, but exFAT patents were not initially included at the time.There was, however, discussion within Microsoft of whether Microsoft should allow exFAT in Linux devices, which eventually resulted in Microsoft publishing the official specification for open usage and releasing the exFAT patents to the OIN in August 2019.A FUSE-based implementation named fuse-exfat, or exfat-fuse, with read/write support is available for FreeBSD, multiple Linux distributions, and older versions of Mac OS X.
