I guess we have to explain to yb_1 the difference between opinion and fact:

There is no problem if someone is guessing that certain military applications of poet could possibly be blocked by the US government. But without evidence this is just an idea, not a fact.

And this is my personal opinin: Foreign forces can - already with the facts published in the POET patents - do their own projects to copy such applications, as they do not care too much about NDA. So if there would be additional ground breaking IP with the POET technology, this IP would not have been published at all in such patents.

The expectations we have in the future of POET is based on published patents, and sooner or later this IP will turn into money - my personal opinion :-)
