Can assignment records be expunged after they have been recorded by the USPTO?
Yes, assignment records can be expunged after they have been recorded by the USPTO, but only through a specific petition process. According to 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 means that once an assignment record has been officially recorded, it cannot be simply removed or deleted. A formal petition must be filed, demonstrating that the document was submitted by mistake or is of improper character. The USPTO will then review the petition and make a determination on whether to expunge the record.
