<As my EE contact has stated to me on numerous occasions, using a ring oscillator to clock a chip and have it "track" is the key to the 336. Just because a ring oscillator was around before the invention doesn't mean it was not an inventive step to use it to clock a chip in a variable manner.>

IMHO, your EE friend is right on target with that statement. That varing together statement is all important. The key that makes the rest of the 336 possible. A ring oscillator clock and cpu could not vary together unless both were constructed of the same materials and placed on the same substrate. That is the point at which all prior art fails.

I suggest a reading the current reexam request and just look for how the requester tries to deal with that huge missing piece of the puzzel in presenting Mostek, Dozier and Ricter.
