-IMO-
All the claims require, with slight language variations, an "entire ring oscillator variable speed system clock." So there's no getting around the fact that we will need to prove a variable speed clock that changes speed with temperature, voltage, or processing.

If the accused circuits just have a ring oscillator that is part of a phase-locked loop (PLL) that is locked onto a (non-variable) quartz crystal, that won't do it. That's the part I'm not sure about. The dedicated micros, like Intel Pentiums, etc., are locked to a crystal frequency (or maybe some other type of non-crystal, but fixed, frequency source). I'm not sure about the smaller micros the bad guys' products use.
-IMO-
Good luck to all.
