The First Patent
X-Patent WIKI page on patent X1
|This is the first recorded United States patent.
The original document is in the collections of the Chicago Historical Society.
Listed in The American Journal of Improvements in the Useful Arts & Mirror of the Patent Office in the United States, V1, #1, 1828, pg. 13.
Only about 2000 of the almost 10000 X-patent documents were recovered.
Because of the Patent Office fire in Dec. 1836, little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.|
