Agreed. That is where it gets "maddening" to use Greg Bailey's term. Once you think it relies on the external crystal, you think about how it oscillates on its own via PV(supply voltage, not control)T, and then say it does oscillate on its own and that is the driver. But does the system work without the control? Does that matter based on the AB Dick precedent from 1982 (from the 30s originally but new challenge in 82) that Jim Otteson uses stating if you patent a, b, and c, and the big companies add d (occasional reference signal control), the big companies infringe. IMO, it is a good argument and IMO will probably come down to the expert testimony and how the Big Companies extracted infor vs how Jim O extracted info. The judge has to buy what we are selling.
