"In closing: One of our engineers examined your ‘Isolation Springs’ and noted there is a “shear component” as well as a “compression component” with a single metal conduit providing a “primary mechanical grounding conductor” which is very similar to our technical approach.

Strange he should ask since just about everyone and his brother knows that mass on spring isolation devices work by attenuating the transmission of seismic vibrations according to a simple mathematical formula. Obviously the isolation effectiveness is a function of the resonant frequency of the iso system and technique in setting up the iso device as I’ve already alluded to. Thus, even advanced iso devices allow some vibration up into the component. Duh! Nobody ever claimed these iso devices are perfect, or that there is perfect isolation. However, by minimizing resonant frequency of the device, maximizing the degrees of freedom one can obtain very good results. Spring based systems are well documented and are a proven technology for vibration isolation. One need look no further than the LIGO project to detect gravity waves to see just how well (talk about understatement) springs do in real science experiments. And by employing tricks of the trade, you know, tricks like cryogenically treating the springs, one can do very well. That’s why my spring based systems have been and are in some of best systems extant. In closing let me turn your opening snarky comment around and ask you, don’t you think you and your engineer could use a little research into vibration isolation?
