Issued: November 1991 Prosecuted by: Chicago’s Lisa & Lisa [now defunct] Licensed by: Gerald Hosier Litigated by: Steven Lisa, Louis Hoffman, Peter Warner and Richard Listingler of Scottsdale, Ariz.’s Patent It. The late inventor Jerome Lemelson received more than 500 patents during his lifetime, but his cluster of 15 “machine vision” patents have brought in the most money and created the most controversy. These patents cover bar code technology used in supermarkets and throughout most industries to track inventory. The cornerstone patent is No. 5,067,012. These patents have generated hundreds of millions of dollars in licensing fees — and made Las Vegas, Nev.’s Gerald Hosier, an electrical engineer-turned-lawyer, a very wealthy man. Hosier, who strikes Lemelson’s licensing deals, has said in Forbes that he’s “not cheap.” Lemelson was a master at working the inefficiencies of the patent system. Critics say that he didn’t patent inventions but that he invented patents, watching where an industry was moving and then amending his patent applications to cover those developments. The original applications on the bar code patents, for example, go back to the mid-1950s. A stable of Scottsdale, Ariz. IP lawyers have formed an alliance, “Patent It,” through which they do nothing but handle Lemelson IP matters, including litigation. The machine-vision patents are being tested in a federal court in Reno, Nev. in a case brought by Cognex Corporation, a manufacturer of bar code�reading technologies located in Natick, Mass. They filed suit in 1998, seeking to invalidate Lemelson’s patents. Trial is expected this fall. The Lemelson Foundation announced that it would not be offering licenses after August 1 “until pending litigations are resolved.” Not a bad move if the patents are invalidated.
