IMO, they did know about it because it was part of the original financing package that allowed them to purchase the Atmel patents.  Also, IMO, there is some financial monkey business going on that has absolutely nothing to do with the company. Per SEC rules the stock cannot go below 35 cents which is an attempt to prevent the kind of engineering that may be happening to Unxl.  If you will recall the all time low is, drum roll please, yes you guessed it 35 cents.  Hopefully the right people will soon realize exactly what is going on and be able to do something about it.  Everything the company is fundamentally doing is heading in the right direction, the tech is excellent and in demand and they are the only "pure play" in a space that has only two other participants.  Very frustrating for now, I still believe.
