For me this is the key quote: > Hoff never even considered patenting the microprocessor. To him the invention seemed to be obvious. I agree with him. The microprocessor wasn’t really an invention - it was a ‘technical milestone’. Once other techniques had been mastered then it was obvious it would happen. Credit to Hoff for spotting that a single chip CPU would work in this case but that was really about being in the right place at the right time. On the other hand Faggin did contribute some real inventions that made the 4004 possible and actually built the thing!
