I don't think I can comment on this due to the Cloudy nights terms of service and disclosure we all signed up for when becoming a member. I have contacted the Mods and explained that I should be listed as a vendor. If the Mods want to move my comments to the vendor forum, then I'm all for it.
The legal stuff is being handled by a patent attorney. So I can't comment on any of those issues.
Now back to the original idea of the thread that Dennis started. Everyone is welcome to make their own mask based off of the design that Dennis has described.
