Alot of company should pay for this patent, to bring a whole new level of experience.
Microsoft Hololens should make use of this.
Honestly depth-sensing is such a heavily used tech now that Sony would really benefit from it in Playstation, its sensor business and also for making dedicated hardware for the professional market. Surprised that Sony's doing well enough to make acquisitions. The last big buy for Sony was Gaikai and that was some 3 years ago.
My guess is that if ever sony closes down or sells its mobile division, it will still continue its development of camera modules for phones and then cater to other OEMs. If I'm not mistaken, the sensor sales for sony modules are quite high.
