Lee Boysel is an American engineer, and entrepreneur. While at Fairchild Semiconductor, he developed four-phase logic and built the first integrated circuit with over 100 logic gates and one of the earliest microprocessors, the Four Phase Systems AL1. He founded Four-Phase Systems to commercialize the technology, and sold the company to Motorola in 1981. Boysel is a graduate of the University of Michigan.
Patent litigation with Texas Instrument
Texas Instruments claimed to have patented the microprocessor, and Lee Boysel in response assembled a system in which a single 8-bit AL1 was used as part of a courtroom demonstration computer system, together with ROM, RAM and an input-output device.
