NX series patents are pre-July 1836 patents that do not have numbers and are not listed in the X patent series. They have been arbitrarily assigned NX numbers, which consists of the issue date in ISO format followed by a single number to separate multiple patents issued on the same date. This is to allow them to be entered into the Datamp file. These patents are listed in A Digest of Patents, Issued by the United States, from 1790 to January 1, 1839, published in 1840. They are entered here for reference and further research only.
