This is good and if able to be used as prior art then even better. The problem I have is patents in general, they are horrible, but they can sink you. So we patented a wide area so that not only is our code 100% free software (GPL3) but also beyond that is as well. I explained this a while back as you invent a very clever blockchian algorithm (for example) and somebody finds an arguably logical step forward (more efficient, safer etc.) and somebody then sees this patents it and effectively stops your code going there now.
It should not happen if the step that got patented is not "novel" but if you see what some patent jurisdictions consider "novel" like one click, rounded phone bevels and more than it's a rotten problem. So for us in a new area we patented things like "ability to log into a completely decentralised network". So if a clever dev makes our auth better then it's covered and protected by the horrible and should not be required, patents.
We could have said, who cares, were doing it anyway and ignore patents, or beat them at their own game, we chose (at great cost) the latter and now I feel no dev will be subject to patent trolls in regard to login to decentralised networks. So hopefully we all win.
Infuriating it is that way and we had to do this, but it is what it is and until humanity wakens up, we have done our bit to protect people taking our work and improving it.
