I'll take it as a no then, that no one here knows of a good reliable way to check on the
most current status of a patent application.

I certainly don't know that.

There are several people here who are referring to the high voltage pulse that occurs
after the driving pulse to a coil is switched off, as 'BEMF'.  BEMF, AKA back EMF or counter
EMF only occurs while a driving EMF is applied to a coil. Back EMF is oriented polarity wise in
such a way that it acts counter to the driving EMF. This is why it is also referred to as counter EMF.
When the driving voltage pulse is switched off, the magnetic field around the coil collapses and creates
the high voltage pulse. This is not back EMF or counter EMF, since the driving EMF is already switched off at this point,
so there is no driving EMF to counter.

You are correct...and the current through the coil does not reverse when that "switch-off" voltage pulse occurs.
This is why I do not use these terms myself and I always put them in quotation marks when talking to someone who uses them.

Thanks Verpies. It would appear that the patent office doesn't always keep the published status
on patent applications very current, but maybe there is some other way to get the current status such as
contacting the patent office directly.

Right. I only mentioned it because it could at least potentially lead to misunderstanding of
what is actually going on in the circuitry. Maybe not a super critical distinction for the matter
being discussed however.

Oh, that will suppress all HV spikes but will limit the bandwidth of this circuit and increase the reactive input power.
It's like putting a capacitor across an alternating voltage source.  No real power, but all reactive power.

P.S.
In ideal transformers, windings are not inductors but alternating voltage sources. A capacitor across such winding does not form an LC circuit, despite that it looks that way on a schematic.
It is as if the transformer's mutual inductance consumes the inductance of a lone winding.

That's correct, we are dealing also with series resonance which is reactive power anyway
So the balance need to be in place for the both yoke halves. And about the frequency bandwidth - the LC resonant frequency still need to be adjusted to the range of grenade coil resonance, so I do not see any problem there.

   All the HV spikes?  What will it do to the one centimeter long (10kV) spikes that are being pulsed from the HV circuit, or Kacher.
  Those KV spikes are going all throughout the induction circuits, as well, and although those spikes are of much higher voltage, they are of much lower amperage. Aren't they also the cause of some of the problems with burnt out induction driver components?  Will the 1500v TVS diodes have any effect on the fets, there? 
  Yes, the 10.000V HV or so is pulsed, I know.

That's not the same circuit.
