The agreement didn't just expire, Samsung terminated it with the express purpose of counter-suing Apple. Note that Samsung to date has not gone after any other Qualcomm customers for increased patent license fees they can hardly claim they are being non-discriminatory. Not sticking to the FRAND terms it agreed to is a pretty bad move on Samsung's part. I believe the EU not happy about this development and is already looking into this so the move could blow up in Samsung's face.
