U.S. Patent Issue Years and Patent Number Ranges
Trying to figure out the year in which a patent number was granted? This handy chart from the U.S. Patent and Trademark is helpful. Remember, even though patents have been issued since 1790, numbered patents only started in 1836.
- This chart is particularly useful to collectors and those interested in antiques and collectibles. Patent numbers are sometimes available on an item of interest, or included in accompanying instructions or other materials about the item.

| (*) 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 they still may 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 (***)The last Statutory Invention Registration (SIR) granted in 2012 is dated December 4, 2012 (H002273). As of March 15, 2013, no SIR has been granted in 2013 See the U.S. Patent and Trademark Office for more detailed information about this table. |
