X-Patent: A Deep Dive into Its Legal Definition and History

Definition & Meaning

X-Patents refer to a specific category of patents issued by the United States Patent and Trademark Office (USPTO) between July 1790 and July 1836. This period is significant because the original patent records from this time were destroyed in a fire in 1836. Approximately 10,000 patents had been issued before the fire, and after the incident, Congress attempted to restore some records from private files. Patents that were successfully reconstructed were assigned numbers beginning with "X," ranging from X000001 to X011280. The first X-Patent, X000001, was issued to Samuel Hopkins in 1790.
