What is the process for expunging assignment records at the USPTO?

The process for expunging assignment records at the USPTO involves:

  • Submitting a petition under 37 CFR 1.59 to expunge the assignment record
  • Providing clear evidence that the document was submitted by mistake or is of improper character
  • Paying the required petition fee

As stated in MPEP 323.01(d): ‘The USPTO will not expunge any assignment records that have been recorded absent a petition pursuant to 37 CFR 1.59.’ This emphasizes the necessity of following the proper petition process for expungement.
