Indeed we do have a patent on this, and if the patent was issued inadvertently, it is a problem that will be solved on a case-by case basis. My question is about the "loosely" and "strongly" coupled differential pairs, and if their nature will interact with the device under discussion...and how? Basically we have two capacitors in the same body with controlled coupling between them and we try to figure out what characteristic impedance fits better the needs, or what other things may matter.
