The patent in your previous post relates to QRR not fumed silica.
The one in you second post relates to a technology using silane gas. And is not related to HPQ or it's technology.
This
link here patent application is owned by HPQ and it relates to plasma arc process and apparatus for the production of fumed silica
That is a Canadian/International application and publication number, which does not show up under the USPTO at this time -- at least with my limited skills. At least it connects HPQ/PYR to their own patent as opposed to the German one but the German one is on the USPTO so when the second one goes there the examiner will be all over there being conflicts, possibly, i.e. delays.
I guess they don't need the USPTO initially but it will help along the way.
From the USPTO site:
The data for this international application is not available.
