Looks like it might be a sharpshooter with screen imbedded rather than a clip on extra / controller. But I don't think it's sufficiently different to the Wii U concept to be actiunably patentable. But who knows? If some aftermarket company makes a very similar thing to the Sony version then Sony suing / charging licensing is likely to be ahead of Nintendo suing / licensing because the Sony patent is more similar than the Nintendo patent.
So If Nintendo wanted to sue / license they would first have to go to court to invalidate the Sony patent.
Anyway, As with a lot of thing mimicking the Wii U game pad, it won't go anywhere on PS4 for the simple reason that only a proportion of PS4 owners will have Move and only a proportion of Move owners will want to buy a sharp shooter. So 3rd parties will generally not want to support the functionality in games that could use the functionality well. Whereas every Wii U owner will have a game pad so 3rd parties can safely put in the effort of implementing such functionality knowing it will be somewhat of a selling point.
On Wii U motion controll WILL be the method for playing FPS. But on PS4 the majority of FPS gamers will continue to use the (inferior for FPS) controller.
