Damn, that's a big law firm you work for. I found only three Aarons, in Massachusetts, Illinois, and California, but I can't seem to find a docket in any of those states that seems to have anything to do with a patent that might be predated by the empeg. (Unless there's some sort of medical or biotech IP in there. I never realized how much of our court system dealt with that stuff.)

I'm sure confidentiality precludes you from telling us which case it is, but some sort of further information would certainly be helpful.
