Even so, it's very similar to how the old RX-7 turbo setup worked (if I remember correctly), so there has to be some new innovation involved here for a patent to be valid.
An alternative interpretation of the schematic is that each different-sized turbo is powered simultaneously, with one cylinder 'group' supplying input to one turbo each and output directed to the plenum. An actuated diverter would be used to siphon output from one turbo into the other, larger turbo. That might provide a smoother power band? Not sure - the leaders and flow-annotations aren't very clear to me (A/C hydraulics and air flow are apparently not treated similarly in schematics).
