Are attorney’s liens against patents or patent applications recordable at the USPTO?
No, attorney’s liens against patents or patent applications are not accepted for recording at the USPTO. This is explicitly stated in the MPEP:
“Documents that are not accepted for recording include attorney’s liens against patents or patent applications. See In re Refusal of Assignment Branch to Record Attorney’s Lien, 8 USPQ2d 1446 (Comm’r Pat. 1988).” (MPEP 313)
This decision reflects the USPTO’s policy on recordable documents and helps maintain clarity in the patent ownership records.
