You need to be very sure exactly what IP you are referring to. Most IP has been done open source core IMO so they are packaging and applying it but they are not scratch developers IMO? Stuff that was impossible 10 years ago and was taking 100 s of hours for aircraft drones and calibration is now off the shelf open source and is just being amended with different parameters . Applying combinations of positioning GPS underwater relative to each other , object avoidance etc is interesting.

I guess what I am saying is what is the specific IP they have developed from scratch?
