I'm not sure of the exact wording of their agreement but I'd imagine that any lawyer involved would have told them that putting their name on a product includes putting ANY name they already have and own, make up or buy from another company, as a matter of technicality. I'm just guessing that, though, but it's typical of lawyers to think that way in writing. Still, I'm sure it might be totally legit for them to invest in something to PREPARE for a 2016 release of a product they can manufacture (for example Jolla, if Nokia was smart enough to plan ahead).
