What have pebble and coin done to get this IP? Just had enough patent lawyers around to patent stuff they happen to be working on ("Method of having an e-ink watchface")?
To be fair, I don't think Pebble was aspiring to be acquired by Fitbit for their IP. They turned down a huge acquisition offer, presumably on the notion of getting bigger. This was just a fire sale which barely returned money to debt holders (and maybe some to investors).
Same thing with Coin. In fact, Fitbit only acquired a portion of that company.
