What if the assignor is not available to correct an assignment document?

If the assignor is not available to correct an original document or execute a new one, the assignee has an alternative option. According to MPEP 323.01(b):

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.

To complete this process, the assignee must provide:

  • An affidavit or declaration identifying the error and requesting correction
  • A copy of the originally recorded papers
  • A cover sheet
  • The required fee for each application or patent to be corrected (as per 37 CFR 3.41)
