"does it make any sense for Edigital to join the race for improving its technology along the new lines?"

Only in mentioning that they are not totally pointed at "flash memory"

And they kind of do just that in their refined 445 patent.

They now have to take what they have and patent processes of......application.

A data security process is in the works....they can then live off that or any other application devised and patented.

They have a number of years to get the best ideas in line and patent them. If others are already fashioning patents around what e.Digitals basics are.....IMO, they can be challenged when ever....or now if they feel they can handle it.....lol

We don't need to sell widgets....just tech to make them function easier. But that's me.
