323.01(d) Expungement of Assignment Records [R-3]
Petitions to correct, modify or "expunge" assignment records are rarely granted. Such petitions are granted only if the petitioner can prove that:
(A) the normal corrective procedures outlined in MPEP § 323.01(a) through § 323.01(c) will not provide the petitioner with adequate relief; and
(B) the integrity of the assignment records will not be affected by granting the petition.
Even if a petition to "expunge" a document is granted with respect to a particular application or patent, the image of the recorded document will remain in the records of the Assignment Services Division at the same reel and frame number, and the image will appear when someone views that reel and frame number. The Office will, however, delete the links to the application or patent that was the subject of the petition, so that no information about the recorded document will appear when someone searches for that application or patent number in the Assignment Historical Database.<
