Ok, it was not clear to me from other emails in the thread.

That's a pity.

To get an insight into their experience in this area. From other emails
in the thread it looked like there is a prior art in this case and IIUC
the orgs in the list above are dealing with a lot of it. I think they
could also provide advice on the further actions like "don't
read/discuss the patents" (to minimize potential for willful
infringement) or "continue as if there are no these patents" (on the
premise that enforcement of these patents is unlikely due to potential
bad PR or to possibility to loose the patent completely in case of
litigation because of the prior art).
I have never interacted with these orgs regarding such matters so this
is pure speculation.
