They demoed prototypes of NUNCHI 9-1-11 @ the SHM.

Obviously demoing to prospective licensees whould have seen same and then some with signed NDA's, after the patents went live.

A prototype of a chip with microSignet inside is an entirely different animal.

The HINT is, they would not further develope working models of their tech if there was zero interst...why make the effort, why spend the money?
