Rev and Last: I don't have the best archive, but I asked myself the same question. My recollection is that Sam originally claimed in their arb announcemnt that "their license" with IDCC contained 2g and 3g terms." (We have nothing to confirm this). If what they claim is true they would be arguing 2g and 3g. However, if the license had no 3g provisions, I can't see how they can try to claim MFL for 3g based upon NOK's 3g license. You have to have a contract to claim MFL.
I recall that Loop (could be wrong) posted that he believed Sam dropped the 3g contention from the arb.
IMO Ghors
