What is Form Paragraph 4.03 used for in USPTO Office actions?

Form Paragraph 4.03 is used by USPTO examiners in Office actions to notify relevant parties about the death of a patent practitioner. The paragraph reads:

Notice of the death of the attorney or agent of record has come to the attention of this Office. Since the power of attorney is therefore terminated, this action is being mailed to the office of the patent practitioner and to the party who originally appointed the deceased patent practitioner. A new registered attorney or agent may be appointed.

This paragraph informs recipients that the power of attorney has been terminated and that a new attorney or agent can be appointed.
