Holy shit pure mechanical beauty 
very smart idea ,
there is also Pinion that makes nice gearbox , and Suntour .
I think it is similar , as concept , to the Honda bike presented some years ago RN01 .
will it withstand the torque that an electric motor has ?
I recently spoke with the engineer that designed the Pinion gearbox , and his product is NOT up to 2000-3000 W of power .
they are planning a more simple gearbox with just 6 speed , for DH use , maybe this can be .

The gearbox looks really cool. I wanna build one.

It's a little odd that the gearbox has quite a different layout to the one described in the patent. The one in the patent uses concentric shafts for the primary and tertiary drives (like the 18 speed pinion gearbox). Maybe they decided they prefer the higher suspension pivot? There doesn't seem to be anything particularly new in their shifting system, looks to be similar to the one described here - http://iris.lib.neu.edu/mech_eng_capstone/69 - only they patented it. It still won't shift to an easier gear well when under load
