It's a bit more convoluted than that.
The patent for the implantable microchip (for both animal and human applications) is owned by Digital Angel Corp. which in turn is owned by Applied Digital Solutions, who also are about to IPO the Verichip Corp. Applied Digital licenses the rights to the human applications from Digital Angel and will spin off that license to the Verichip Corp.
The chips themselves are manufactured by Raytheon (article cite).
Thanks for the clarification. I was trying to keep it simple enough for our FRiend forrestroche.
A wasted effort, I suppose, but I did try.
