Jerome Lemelson, holder of more than 600 patents

As one of the most prolific inventors of all time, Jerome Lemelson (on the right, above) devised technology that was used in products ranging from cordless phones to warehouse robots to camcorders. But the inventor is perhaps best known for the fact that he filed and was awarded more than 600 patents--more than any other American except for Thomas Edison. And like Edison, Lemelson wasn't afraid to pursue infringement claims. Though he lost some major lawsuits, Lemelson eventually won an estimated $500 million in various settlements. He died in 1997, and left part of his fortune to a foundation that now presents a half-million dollar prize each year to great inventors for their work.
