Seems questionable
“The method for finding a lost device would not exist today if I hadn’t invented it, and, Passbook relies fundamentally on my previous invention for redeeming electronic tickets with a barcode,”
I'm pretty sure that's not how patents work. If you invent something once, you don't then get credit for every future invention that makes use of it somehow. If Apple are screwing this guy out of credit for work he actually did that's one thing, but his own claims make it sound as though he's trying to claim credit for other people's work just because they happened to base some of it on something he'd done in the past. Which is also consistent with Apple's claim that it was an unrelated group who happened to read the work he'd already published.
