Patents
His notes held the seeds for more than 60 patents, most notably U.S. patent number 3,138, 743, filed by TI on May 6, 1959, for miniaturized electronic circuits. We know it today as the integrated circuit.
Many of Kilby’s patents focused on improvements in integrated circuit design and manufacturing, including those the U.S. Air Force used in 1961 in the first integrated circuit-powered experimental computer. In 1965, Kilby and researchers in his TI lab invented the semiconductor-based thermal printer, which printed on heat-sensitive paper.
Two years later, he and two colleagues built the first handheld calculator, based on a set of integrated circuits capable of performing addition, subtraction and multiplication. It had a small keyboard with 18 keys and a visual output that displayed up to 12 decimal digits. TI’s patent for that calculator lies at the heart of all of today’s pocket calculators.
Kilby received his final patent in 1997, eight years before his death, for a method that improved the interconnections among integrated circuits.
