My understanding is DM/EDIG jointly agree on which firms to go after, such as tier 1 being 774, DM alone decides the timing and the quantity for each round, DM along with input from EDIG determine the "level" of infringement 1 by 1 and come up with a settlement demand with desired terms, such as whether or not a XLA will be included or used to help facilitate a settlement, add value, yet accepting less cash, DM negotiates the best deal they can get, EDIG alone decides whether to accept, reject and/or counter offer, then EDIG makes the final decision, and DM takes it from there.

I offer this understanding on my part from comments, Q&A at 2 SHM's, a few things I learned from my personal visit last Sept, plus various phone calls and e-mails to RP in which that info is posted here.

A summary understanding that may not be entirely accurate, but IMO close enough for engineering puposes as the phrase goes.
