I haven't heard that they have used that tech for quite some time. It is referred to as "previous" work in the July 20 2015 Spider Sense. Nothing current, so it is hard to know.
Now I don't know that they want to be forthright with any information to protect their IP.

For KBLB, technical textiles target is 130B, Medical, apparel, filters, etc.....who knows how big the markets are. The market cap disparity doesn't surprise me, and I think KBLB's eventual market cap will blow away many folks, once we know how Kim structures deals....if we ever know.
