U.S. terminates patent application proceedings for fraudulent use of signature
By Ferraiuoli LLC

The United States Patent and Trademark Office (USPTO) issued a final order terminating proceedings in roughly 3,100 patent applications for the fraudulent entry of the S-signature of a registered practitioner by someone other than the practitioner.
Under the patent rules (37 CFR 1.4), signatures on papers submitted to the USPTO must be personally inserted by the named signatory, and the USPTO may require evidence of the authenticity of a signature. Submission of papers for any improper purpose, such as to deceive the USPTO or evade the rules, may result in sanctions (37 CFR 11.18).
In October 2022, the USPTO contacted a practitioner whose signature appeared on a large number of micro entity certification forms received by the agency. Upon further investigation, with the cooperation of the practitioner, it was discovered that the signature of the practitioner was being used by another person.
Due to the improper use of a practitioner’s signature, the submission of papers for improper purposes, and the violation of the duty of candor and good faith, the USPTO has issued a final order terminating proceedings in the applications in which this conduct occurred.
