In order for either one of the PA's I work with to answer this question, they would have to fully understand our patents, and the extent of the claim modifications made during the reexam process...which they do not. This is why I only ask them questions about process, and in this case, I think we know what will happen if the claims are as TPL states "substantially unaltered", or as the opposition states, "substantially modified". This IMO would be more of a question for an EE who works in the industry.

Good luck everyone!
