Key Rules
Assignment and Ownership (MPEP Chapter 300)
See 37 CFR 3.34. The party requesting correction should also submit a copy of the original cover sheet, to facilitate comparison of the corrected cover sheet with the originally recorded document.
The party filing the corrected cover sheet should check the box titled "Other" in the area of the sheet requesting "Nature of Conveyance," and indicate that the submission is to correct an error in a cover sheet previously recorded. The party should also identify the reel and frame numbers (if known), and the nature of the correction (e.g., "correction to the spelling of assignor’s name" or "correction of application number or patent number"). The Office will then compare the corrected cover sheet with the original cover sheet and the originally recorded assignment document (or other document affecting title) to determine whether the correction is typographical in nature. If the error is typographical in nature, the Assignment Recordation Branch will record the corrected cover sheet and correct the Assignment Historical Database.
A party who wishes to correct a typographical error on a recorded cover sheet must submit the following to the Assignment Recordation Branch:

Official MPEP § 323.01(a) — Typographical Errors in Cover Sheet
Source: USPTO323.01(a) Typographical Errors in Cover Sheet [R-01.2024]
A party who wishes to correct a typographical error on a recorded cover sheet must submit the following to the Assignment Recordation Branch:
- (A) a copy of the originally recorded assignment document (or other document affecting title);
- (B) a corrected cover sheet; and
- (C) the required fee for each application or patent to be corrected (37 CFR 3.41).
See 37 CFR 3.34. The party requesting correction should also submit a copy of the original cover sheet, to facilitate comparison of the corrected cover sheet with the originally recorded document.
The party filing the corrected cover sheet should check the box titled “Other” in the area of the sheet requesting “Nature of Conveyance,” and indicate that the submission is to correct an error in a cover sheet previously recorded. The party should also identify the reel and frame numbers (if known), and the nature of the correction (e.g., “correction to the spelling of assignor’s name” or “correction of application number or patent number” ). The Office will then compare the corrected cover sheet with the original cover sheet and the originally recorded assignment document (or other document affecting title) to determine whether the correction is typographical in nature. If the error is typographical in nature, the Assignment Recordation Branch will record the corrected cover sheet and correct the Assignment Historical Database.
I. TYPOGRAPHICAL ERRORS IN COVER SHEET THAT DO NOT AFFECT TITLE TO APPLICATION OR PATENTIf the original cover sheet contains a typographical error that does not affect title to the application or patent against which the original assignment or name change is recorded, the Assignment Recordation Branch will correct the Assignment Historical Database and permit the recording party to keep the original date of recordation.
II. TYPOGRAPHICAL ERRORS IN COVER SHEET THAT DO AFFECT TITLE TO APPLICATION OR PATENTIf the original cover sheet contains a typographical error that affects title to the application or patent against which the assignment or name change is recorded, the recording party will not be entitled to keep the original date of recordation. Rather, the Assignment Recordation Branch will correct its automated records and change the date of recordation to the date the corrected cover sheet was received in the Office.
