How can I request expungement of an assignment record?

To request expungement of an assignment record, you need to submit a petition to the USPTO. According to MPEP 323.01(d), the petition should:

  • Clearly identify the assignment record document to be expunged
  • State the reason for expungement
  • Include the fee set forth in 37 CFR 1.17(g)
  • Provide a copy of the original assignment record to be expunged (if available)

The petition should be mailed to the Mail Stop Assignment Recordation Services, Director of the USPTO.
