FWIW, per the Google page [3] for the patent [4] this IBM patent is
set to expire on 2024-02-02 ... so in just a few days! ;)
With this said, I wonder what is the interplay between the
patent-related terms of the MPL in Hashicorp's code and the patent
from IBM who is not Hashicorp. And what is the impact on the MPL
licensing?
A well known example is FFmpeg with L/GPL-licensed but patented media
codecs. [5]
