Default Amplifier Utilizing Two-Stage-Included Local Negative

I came across this today, Low Cost High Performance Power Amplifier Utilizing Two-Stage-Included Local Negative Feedback with Feedback-Shifting Technology and I am wondering whether I should quickly forget about it or whether it would be worth implemeting in a simple class A circuit.
Any comments positive or negative are welcome.

Fig. 10 shows (if my eyes aren't playing tricks on me) N-JFETs where I suspect he meant P-JFETs.

the block diagram in the patent made me think about the old nested feedback loop designs.
