"Negotiate the price" also takes the Apple position (though you probably think this is legit because of a recent Posner comment).
If you said "compel the license" or "enforce the patents" you would be better describing the purpose of the first veto.
These are FRAND patents - there really isn't much room for negotiation.
Huh? Did you read the case behind the first veto? Apple offered to license SEPs but Samsung said they're not SEPs, so they then went to ITC to claim patent infringements instead because Apple refuses to pay the much higher rate that Samsung has demanded. FRANDs explicitly said you cannot do this if your patents are declared SEPs, it must be the same price to be fair to everybody who licenses these SEPs, regardless of what Samsung said.
You're right that there is no room for negotiation for FRANDs, but Samsung says they're not FRANDs and therefore there's room.
