Abstract
Before patent examiners and rejection letters, before attorneys drafted claims in careful legalese, America invented freely. Between 1790 and 1836, nearly 10,000 patents were issued to inventors who simply submitted a description of their idea and paid a fee. Farmers, engineers, and industrial visionaries filed patents on everything from cotton gins to chain bridges, and a nation built itself around their ingenuity.
Then in 1836 a catastrophic Patent Office fire destroyed the records of what are now called the X patents.
Unfettered Invention recovers this vital chapter in U.S. innovation. Drawing on newly discovered archival materials, from auction catalogs to courthouse filings to the pages of the 19th century Franklin Journal, the authors provide an eye-opening account of the origins and impact of early American patents.
Part legal history, part technological archaeology, part detective story, Unfettered Invention is a unique, must-read book about the X patents, their inventors, and the raw, unfiltered burst of ingenuity that ignited and shaped America’s appetite for innovation.
