The list includes an amazing array of corporations: old-economy stalwarts like Alcoa, Boeing, Dow Chemical, Eli Lilly, and GE; manufacturing behemoths like Ford, GM, and U.S. Steel; technology titans like IBM, Hewlett-Packard, and Cisco. The portfolio of products covered over the years by Lemelson's patents is equally staggering: They include components in such everyday consumer products as the Walkman, the VCR, the fax machine, and the camcorder. At one time or another his patents have covered Velcro darts and industrial robots, crying dolls and semiconductors. He even holds patents--perhaps his most important ones, as we'll see--on the ubiquitous bar-code scanner.
