This doesn't necessarily mean JPEG XL is patent-encumbered (the patent is still annoying, but not necessarily this way). It is recommended for ISO standards that relevant patents should be disclosed and available on a non-discriminatory basis [1], and while patent holders can ignore this recommendation they generally have no reason to do so. In the case of JPEG XL only Google [2] and Cloudinary [3] filed patent declarations, so Microsoft is reasonably thought to have no patents relevant to JPEG XL.
