Who holds patents awarded in the 1950s for automatic video scanning and inspection methods, which led to bar code technology?

Actually no one holds the patents award in 1950s automatic video scanning and inspection methods, because in 2005, the United States Court of Appeals for the Federal Circuit has sided with a federal judge in Nevada that concluding barcode scanning patents claimed by the estate of late inventor named Jerome Lemelson and held by Lemelson Medical, Education and Research Foundation LP in January 2004 were absolutely invalid and unenforceable.
