Is the design and manufacturing processes for the most power efficient ASICs otherwise patent unencumbered? If not, why do we care so much about this one patent over all the others that stand on the road between pen and paper computation and thermodynamically ideal computation?

Taking that a step further, the old POW could continue to be accepted
but with a 20% target penalty. (or vice versa, with the new POW having
a 20% target boost.)
