    Some potentially relevant light reading...

    https://patents.google.com/patent/US20100300777A1/en

    https://patents.google.com/patent/US9775755B2/en

    So, are each of those the same? I dunno how patents work.

    Here is the category:

    Each of those talk about lifting the rear wheels off the ground. Otherwise the new device is completely up the creek. The question might be is the purpose and function the same as what is described in the patent? I know nothing about patents, Pat does, they need to take heed.

I'm all for new ideas but this one lacks common sense and simple physics.

    Omnidirectional drive wheels look cool but they'd only be useful when the motors are off and they are in freewheel mode, assuming they have brakes, and you want to turn your chair manually. I see no other reason. There are so many other problems but I guess they'll find out during testing.
    Pat, you patent is a work of art.

    I think the omni wheels will work if they can control them for all speeds, but they might not be spaced far enough apart for control. I've never figured out how their brake claim works especially now after reading the complete unit only weighs 11 lbs. That suggests motors smaller than standard bicycle hub motors, (my hacked smartdrive, one motor, no battery is 10 lbs).
