Possibly. They must be getting their idea out 99% from somewhere, and existing transmissions in other application domains are a likely candidate. But I really don't believe that it could work at bike-friendly torque/weight ratios, in a system open to the gritty environment, in a multi-gear setup where angles are not aligned (the inner part of the teeth moves slower than the outer part, permanent slippage, yay). As far as I understand it this is a mockup celebrating the intention of getting to 99, not a prototype that has achieved it. More artist's impression than product. What's still impressive though is that the concept does away with pretty much the only actual product the company has, the pulley wheel. That is bold in a strictly economic way.
