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 the List of Patents for Inventions and Designs, published in 1847. They are entered here for reference and further research only. |
