"I'm guesstimating the T2's could have tied the ring oscillator circuit to voltage and heat sensors on the hard drive or other components and try to claim that it was different enough to circumvent our patent claim or claims. Therefore, they will claim there was no infringement."

People here that are smarter than me can correct me if I'm wrong, but if in fact the T2's did what you're saying, they would in fact NOT infringe. Nor would we be going after them in that case.
