Things that sound very similar to those without background may be very different. From what I can see, it appears that Vecoy is using chemistry that Dr. Diwan (Theracour/NNVC) did not include in his patent claims because it was inherently toxic and he didn't see it as worth bothering to cover.
Let Vecoy do what it can with the "dregs" and leftovers. It won't be any competition for NNVC, IMHO. Dr Diwan was many years ahead of Vecoy and if there is any infringement it will be by Vecoy, not NNVC
But again, it appears that Vecoy is working with the "leftovers".
