Please provide me the Procedures for Correcting Errors in Recorded Assignment Document for the United States Patent & Trademark office as I need it for making some correction?

An error in a recorded assignment document will be corrected only by Assignment Division provided a “corrective document” is submitted. The “corrective document” should include the following:

(A) A duplicate of the original assignment document with the corrections made therein. The corrections must be initialled and dated by the party conveying the interest; and
(B) A new Recordation Form Cover Sheet along with form PTO-1595.

The new recordation outline cover sheet must identify the submission as a “corrective document” submission and indicate the reel and frame number where the incorrectly recorded assignment document appears. The original cover sheet must be submitted with the corrective document. The corrective document will be recorded and set a new reel and frame number and recording date. The recording fee set forth in 37 CFR 1.21(h) which is required for each patent application and patent against which the corrective document is being recorded.

Corrections may be prepared on the original assignment document, for example, by lining out an incorrect patent or application number in a merger or change of name

Office policy concerning recordation of assignment documents is directed toward maintaining a complete history of claimed interests in property and, therefore, recorded assignment papers will not be expunged even if subsequently found to be invalid.

Once a manuscript is recorded with the Assignment Services Division, the Assignment Services Division will not remove the papers from the record relating to that application or patent.
