(*) The current patent numbering system began with a patent issued on July
13, 1836. Prior to that date, 9,957 patents had been issued. The user
should note that the data in this table have been checked but that it may
still not be completely devoid of errors.

Numbers, as displayed in the table, are 7 characters with the numeric
portion padded with leading zeroes where necessary.

Note that 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.

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

(***) Defensive Publications and Improvement (AI) patents are not included
in this table.

Dates and Patent Numbers Since 1836, may also be of interest. However, this
report requires the Adobe Acrobat Reader for viewing and printing.
