Wow, getting a drone to survive the massive electromagnetic fields (and plasma!) around lightning strikes is quite an accomplishment. Prior art in the area used rockets trailing a similar light wire to trigger lightning - used by Dr Uman's team at University of Florida (https://ufdc.ufl.edu/UFE0047331/00001).
Aren’t lighting strikes on aircraft a pretty common occurrence and even without that the charge on the skin of an aircraft flying through the air is quite substantial.
And the prior art before that involved a kite and a key
Rockets triggering lighting with wire has been since the late 50's (M. M. Newman), what's cool about the drone is you can send back data before the strike. Obviously a kite or aerostat would work as well.
I'm sure someone in the 90's was using rockets without wires, the exhaust from the rocket made the trail. I cannot source it.
These guys charging cars shows they are not really serious, but a lot of forest fires are lightning, it's a worthy thing to control if possible.
