Early Microprocessor Revisionist History: Gilbert Hyatt
In the confusing hustle and bustle that led to the first microprocessors, a few players were mistaken for pioneers, but in retrospect turned out to be up to something else. For example, an engineer named Gilbert Hyatt in 1990 fought for and won patent for a 1968 invention of a “single chip microprocessor.” That date put Hyatt’s patent ahead of both TI and Intel. TI quickly challenged the patent office’s ruling by asserting that Hyatt’s invention was never implemented nor was it possible to implement it in 1968 with then-available technology. Gilbert Hyatt’s patent was invalidated.
