More particularly, the present invention relates to biasing a dielectric with an electrical or electrostatic potential to reduce undesirable electrical properties of the material such that signal quality between the electrical devices is enhanced.It doesn't say or mention what is biasing the dielectric.
As for reducing undesirable electrical properties of the material, that can be another way of saying that it's making it (the dielectric) resistant to RFI without the need to spell it out, rendering the patent moot so others can't copy it.
And, in that link you provided, AQ states that they finally found a way to use DC as a shield to reject RFI and EMI, so where did I misunderstand things, and just where did the reviewer get it wrong as well?
How you can read into it that I am being contrary is just plain silly.
All the best,
