In Re STANLEY A. SANSONE,
Petitioner
2026-124
On Petition for Writ of Mandamus to the United States Patent and Trademark Office in Nos. 16/255,511 and 17/490,525.
ON PETITION AND MOTION
Before DYK, REYNA, and HUGHES, Circuit Judges.
O R D E R
Stanley A. Sansone petitions for a writ of mandamus related to the United States Patent and Trademark Office’s (“PTO”) handling of his patent applications: U.S. Patent Application Nos. 16/255,511 and 17/490,525. He also moves to proceed in forma pauperis.
A writ of mandamus is an extraordinary remedy and may only issue if a petitioner has shown a clear and indisputable right to relief and there are no other adequate means to attain the relief desired. See Cheney v. U.S. Dist.2 Ct. for D.C., 542 U.S. 367, 380–81 (2004)). Mr. Sansone has not met this demanding standard.
As to U.S. Patent Application No. 16/255,511: Mr. Sansone has not shown entitlement to a writ regarding the PTO’s denial of his petition to withdraw its notice of abandonment, see In re Makari, 708 F.2d 709, 711 (1983) (“We do not have jurisdiction to review decisions” of the Director “on petitions”), or that he has no available alternative means to obtain relief on his challenge.1
As to U.S. Patent Application No. 17/490,525: it appears the PTO, on October 21, 2025, issued a Notice Requiring Extension of Time Fee predicated on Mr. Sansone’s failure to file a timely reply to an October 3, 2025 Office Action, Appx 61–62. While he appears to contend that the examiner afforded his response an incorrect date of receipt, he has not shown inadequacy of the PTO’s process to accord a different filing date, see MPEP § 503.IV, or otherwise shown a clear and indisputable right to relief.
Accordingly,
IT IS ORDERED THAT:
(1) The petition is denied.
3(2) The motion to proceed in forma pauperis is granted.
