Although only the original is signed, the word "Examiner" and the name of the signer should appear on the original and copies.
All Office actions and other correspondence should be signed promptly.
The original, signed by the authorized examiner, is the copy which is placed in the file wrapper. The character of the action, its paper number and the date of mailing are entered in black ink on the outside of the file wrapper under "Contents."
The mailing date should not be typed when the Office action is written, but should be stamped or printed on all copies of the action after it has been signed by the authorized signatory examiner and the copies are about to be mailed.
