What documents are needed to correct a typographical error in a patent assignment?

To correct a typographical error in a patent assignment, you need to submit several documents. According to MPEP 323.01(b), the required documents include:

  • A copy of the originally recorded papers
  • A cover sheet
  • The required fee for each application or patent to be corrected

If the assignor is not available to make the correction, the assignee must also provide:

  • An affidavit or declaration identifying the error and requesting correction

The MPEP states:

If an assignor is not available to correct an original document or execute a new one, the assignee may submit an affidavit or declaration in which the assignee identifies the error and requests correction. The affidavit or declaration must be accompanied by a copy of the originally recorded papers, a cover sheet, and the required fee for each application or patent to be corrected (37 CFR 3.41).

Ensure all documents are properly prepared and submitted to avoid delays in processing.
