Define 'Fair and Reasonable'
If Samsung have already licensed their patents to other firms who have agreed their price is indeed fair and then offered them to Apple at the same rate that seems fair. If Apple have refused the same terms offered to other manufacturers then it is Apple being unreasonable. As far as I understand it from various reports this is the case and Apple are the ones who have thrown their toys out of the pram because Samsung wouldn't give into their unreasonable demands to get a lower rate than other companies. Samsung quite rightly have stood their ground and said they don't care how big Apple are, they pay the same rates as everyone else.
If that isn't the case and Samsung are trying to charge Apple more than other companies then of course they are in the wrong, although given Apples attitude towards them recently I don't blame them for trying it on.
