"Shuji Nakamura was just another rebellious inventor who had succeeded by trusting his instincts and ignoring the guys in suits. When his superiors at Japan's Nichia Corporation told him to stop wasting time on blue light-emitting diodes (LEDs), he pressed on anyway. As a result, blue LEDs are now used in everything from optical scanners to traffic lights, earning Nichia a tidy sum."
[A tidy sum, indeed. In January 2004, a judge agreed that Nakamura should share in profits arising from the patent and awarded him ?20 billion ($190m).]
