What is the process for expunging assignment records?

Expungement of assignment records is a rare and complex process. According to MPEP 323.01(d), petitions to expunge assignment records are granted only under specific conditions:

  • Normal corrective procedures (outlined in MPEP § 323.01(a) through § 323.01(c)) are inadequate for providing relief.
  • The integrity of the assignment records will not be affected by granting the petition.

It’s important to note that expungement does not result in the complete removal of a document from assignment records. Instead, a redacted version of the ‘expunged’ document is recorded and replaces the original in the assignment records.
