techwiz, I think you've hit upon the basic question...

What is the potential level of infringement (numbers of products and their value) covered by the claims which are currently being re-examined? Presumably these are the key claims that will be used in the next round of filings assuming the re-exam is successful.

One would think that they already have some idea regarding the scope of infringing products, else why pursue the re-exam in the way that they have? I certainly can't tell where they're headed with this strategy though. It was one thing to think of cell phones as effectively having flash voice-recorders contained within them. But I'm unable to imagine what nugget of gold could possibly be buried within these old patents that EDIG/DM also believes they can monetize... and that no one had noticed before.

Regardless, the company apparently believes the re-exam IS worthwhile since they're spending real money on it.
