contrary to popular notion, U.S. Patent No. 4,344,142 to James Diehr was not the first attempt to patent the idea of performing a real-time simulation of the Arrhenius equation using periodic temperature measurements of a rubber mold in order to cure rubber. In fact, nearly two years prior to Diehr’s filing, Thomas Smith filed for a device that performed the very same algorithm using dedicated logic, which was granted as U.S. Patent No. 3,819,915. Smith was also granted U.S. Patent No. 4,022,555 for another rubber-curing device based on discrete logic. Similarly, William Claxton filed for patent protection in 1974 for an Arrhenius-based rubber-curing device using analog components, which issued as U.S. Patent No. 4,044,600.
