Possibly to MS? I have not heard anything official about it. Some heavily Lumia linked patents switched hands to MS. Described being design patents. What we do know is that Tampere team, that has been behind all the major camera innovation on Nokia since N93 moved to MS. PureView was all result of the Tampere team.

As for N1. Industrial design was on Nokia and hardware was designed in partnership with Foxconn. Nokia has no sales channels anymore on consumer devices, so that's all on Foxconn. Why N1 is coming to China first and Europe who knows when.

Jolla already did its last device in a partnership with two Finnish companies. Nokia could indeed invest to a device and offer some design help, but I think robust sales channels are critical for Jolla. Something Nokia can't offer.
