What to expect
This patent dispute matters because of the people and ideas involved, not because a visitor can walk into an exhibition at the map marker. It is an unusual strand of Las Vegas technology history rather than a conventional sightseeing stop.

The story
Gilbert Hyatt’s place in microprocessor history is complicated, which is precisely why Plot Luck treats it as a story rather than a simple “invented here” plaque. In 1990, after a patent process that stretched across roughly two decades, Hyatt received U.S. Patent No. 4,942,516 for a “Single Chip Integrated Circuit Computer Architecture.” The award triggered immediate debate over priority and the history of the microprocessor.
Hyatt argued that work he began in the late 1960s placed him ahead of better-known industry efforts. Texas Instruments and others disputed that conclusion. The U.S. Patent and Trademark Office later ruled in an interference proceeding in favor of TI engineer Gary Boone on the contested single-chip claim, and contemporary technology histories generally treat Hyatt’s claim as disputed rather than as a settled answer to “who invented the microprocessor?”
What makes the story specifically Las Vegas is what happened afterward. Hyatt moved to the area and continued inventing and fighting long-running patent battles from Southern Nevada. A 2014 Las Vegas Sun profile described him as a local inventor still pursuing recognition and patent applications decades after the original controversy.
Plot Luck deliberately avoids sending players to Hyatt’s private home or research space. The game uses the Lloyd D. George U.S. Courthouse in downtown Las Vegas as a public anchor for the broader Las Vegas patent story. The courthouse connection reflects later federal litigation involving Hyatt and the Patent Office while keeping the discovery on an appropriate public civic site.
Why it belongs in Plot Luck
This story expands “Las Vegas history” beyond casinos. It is about technology, invention, patent law and the difference between a famous claim and a settled historical conclusion.
Plot Luck’s public history pages are separate from the reward authority. Reading this page does not claim a reward. The live game decides physical-visit eligibility from its existing trusted location rules.
