That implies that Intel has the leverage. Intel's BATNA is to just let the modem IP rot. It's a sunk cost. They can just walk away from the negotiating table, and they'll be choosing to get $0 + ($small * potential of selling to anyone else = $ε) instead of $1B.

Apple's BATNA, meanwhile, is for Qualcomm to steamroll them and force them into expensive concessions across the board, and they're willing to pay through the nose to avoid that. Their choice is between $1B to intel and likely far more than $1B to Qualcomm.
