How do I correct a typographical error on a recorded cover sheet for a patent assignment?

To correct a typographical error on a recorded cover sheet for a patent assignment, you need to submit the following to the Assignment Services Division:

  • A copy of the originally recorded assignment document (or other document affecting title)
  • A corrected cover sheet
  • The required fee for each application or patent to be corrected

Additionally, it’s recommended to submit a copy of the original cover sheet to facilitate comparison. When filing the corrected cover sheet, you should:

  • Check the box titled “Other” in the “Nature of Conveyance” area
  • Indicate that the submission is to correct an error in a previously recorded cover sheet
  • Identify the reel and frame numbers (if known)
  • Specify the nature of the correction

As stated in MPEP 323.01(a): “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.”
