If you read the post from sman998 from 2006 I think it was (?) this private company had estimated sales between 2.5 & 5 mln.

Lets take a wild guess and say today it's 5 mln, so what would the 1 time fee be? $100K, $500K? Who knows.

Royalty per yr of how much?

I'm guessing the realistic answer to your question is a small figure for both, thus little reaction. Put the likes of a Panasonic in that PR then lets talk.
