I see misdirection in that thread. As I already pointed out, having at least 1 claim meet all 3 criteria is actually favorable and seems somewhat hard to do based on it qualifying for fast tracking. The ISR gives no indication the patent has a slim chance.to be awarded and seems favorable.
Antiviral maybe intrinsic in Si3N4, however, they developed a powder that lets them infuse the material into various other materials. This could be seen as proprietary.
Still the way patents work, if you are first to have the idea to use a material for a specific application, then you can have the patent awarded.
I see nothing indicating, based on the information provided, that suggests they will not be awarded a patent or even that's there's a slim chance.
FYI the 2 accounts talking are the same person.
