Thanks for your invitation, ease; however my opinion is irrelevant. There is a technical definition of a ring oscillator, and there are practical considerations in building and using them, but those are not necessarily the definitions lawyers and judges would be using. This discipline (IP litigation) does not seem to be about practical engineering or logic, but rather about semantics that would drive anyone but a barrister mad. Under those conditions, public comments by *any* engineer might have unintended consequences!
I work you well... Greg
