A Publication Number number includes a four-digit year, followed by a seven-digit sequence code followed by a two-character Kind Code that is assigned by the USPTO. The system displays the publication number with or without the "US" prefix and the Kind Code suffix (e.g., US YYYY-9999999 A9 or 9999-9999999).
The publication's two-character alphanumeric kind code (that is, kind-of-document code) will be determined by the < application-type > and the < publication-filing-type >. See the table below.
Each application's < application-type > field value will be either "utility" or "plant."
Each application's < publication-filing-type > field value will be one of the eight values shown in the leftmost column of the following table.
| "utility" Kind Code | "plant" Kind Code | |
|---|---|---|
| new | A1 | P1 |
| new-utility | A1 | P1 |
| voluntary | A1 | P1 |
| original-publication-amended | A1 | P1 |
| original-publication-redacted | A1 | P1 |
| republication-amended | A2 | P4 |
| republication-redacted | A2 | P4 |
| corrected | A9 | P9 |
