Abstract
The first American patents issued by the United States Patent and Trademark Office (USPTO) were designed as X-Patents. About ten thousand were issued, from July 1790 to July 1836, by almost 7000 inventors, following the Patent Acts of 1790 and 1793. Patents had come of age. Unfortunately, most documents (around 75%), that were just named and dated, were burned in a fire, which occurred on December 15, 1836. Such documents received this specific identification (X-Patent) because they were retrospectively renumbered. We applied new procedures such as data mining to arrive at new correlations and results. For example, it was possible to find first, middle and last names of inventors, assignees, witnesses and manufacturers in most patents. The objective is to describe the earliest United States patents and present some landmarks that cover almost half a century and constitute the dawn of innovation and the rise of the Industrial Revolution in America.
