All Assignees Field (AN)
AN is a special field code for searching all of the assignee fields at once. This includes the original, guessed, current, and chain of custody variants, in their normalized and non-normalized states. While not precise (at all, really), it is often helpful for cleaning up lists, and for seeing if there are any outliers that our normalization team missed.
- AN:seimens --> Finds documents with this specific misspelling in any of the assignee fields.
Note: You can also use field codes, like the AN_ORIG field code, for a similar search. However, the AN_ORIG field code searches only for the original assignee name as written on the patent, including punctuation, misspellings, and creative names.
