(*) The current patent numbering system began with a patent issued on July 13, 1836. Prior to that date, an estimated 9,957 patents had been issued. Defensive Publications (T) and Improvement patents (AI) are not included in this table.

(**) Reissue patents were not separately numbered until 1838.

Some patent numbers, as displayed in the table, are 7 characters with the numeric portion padded with leading zeroes.

Some numbers within a series may be unused. Therefore, the number of patents granted during a year cannot be determined by simply subtracting the number of the first patent issued in one year from the number of the first patent issued in the next year. The user should note that while the data in this table have been checked, it still is possible that inadvertent errors remain.

A detailed Patent Technology Monitoring Team report, titled Issue Dates and Patent Numbers Since 1836, which contains first patent numbers and the day of issue for patents issued since 1963, also may be of interest.

In addition, the Patent and Trademark Office has a file that lists all patent numbers and their associated dates of grant. That file may be accessed from: . See the link labeled, "Click here to download the zipped Patent Grant Authority Files".
