¶1Before MARKEY, Chief Judge, and MILLER and SMITH, Circuit Judges.
¶2ORDER
¶4Petitioner Jack G. Makari (Makari) seeks reconsideration of this court’s May 5, 1983 denial of his April 28, 1983 petition for a *710writ of mandamus directing the Commissioner: (1) to change the filing date of abandoned application Serial No. 75,454 from August 26,1959, to August 4,1959; or (2) to consider the merits of his petition filed July 27, 1982 in Application Serial No. 06/370,517. On reconsideration we dismiss the petition.
¶5I.
¶6On August 4, 1959, the Patent Office received Makari’s application Serial No. 75,-454 (’454), accompanied by an oath taken before a postmaster. On August 12, 1959, the Application Branch of the Patent Office issued a “Notice of Incomplete Application”, advising that the oath was defective.
¶7Makari signed a new oath before a notary public, returned it to the Patent Office on August 26, 1959, and petitioned the Commissioner to grant his application a filing date of August 4, 1959. In an affidavit accompanying the petition, Makari stated that the Postmaster in Plainfield, New Jersey advised him that because the patent application was to be filed in an Office of the United States Government, the Postmaster was authorized to take his Oath and that it was not necessary for him to execute the papers before a Notary Public.
¶8On February 2, 1960, Assistant Commissioner Crocker denied the petition because the original oath was not made before a “person within the United States authorized by law to administer oaths” under 35 U.S.C. § 115 and, therefore, the application received on August 4, 1959, was incomplete under 35 U.S.C. § 111. Makari twice requested reconsideration without success. Pursuant to Crocker’s decision, adhered to on reconsideration, the Office treated the ’454 application as filed on August 26, 1959.
¶9On December 11, 1964, Makari again petitioned the Commissioner to grant the ’454 application a filing date of August 4, 1959, relying on 35 U.S.C. § 26.1 Assistant Commissioner Reynolds denied that petition on March 22, 1965, stating that “Section 26 of Title 35 of the United States Code enacted March 26, 1964 was not retroactive and did not apply to papers filed during 1959."
¶10Makari filed application Serial No. 925,-469 (’469) on July 9, 1978, the seventh application in a chain beginning with the ’454 application. All six preceding applications are now abandoned.
¶11The claims of the ’469 application were rejected under 35 U.S.C. § 103 as unpatentable over an article authored by Makari and published in the British Medical Journal on August 9, 1958. According to Makari, that publication would not be available as a reference if the ’454 application were granted a filing date of August 4, 1959.2
¶12On August 31, 1981, Makari again petitioned the Commissioner to change the filing date of the ’454 application.3 On January 29, 1982, R. Franklin Burnett, Special Assistant to the Assistant Commissioner, dismissed the petition on two procedural grounds: (1) the petition was untimely under 37 C.F.R. § 1.181(f), providing that any petition “not filed within 2 months from the action complained of, may be dismissed as untimely”; and (2) under 37 C.F.R. § 1.184,4 the issue of the correct filing date, *711previously decided by two Assistant Commissioners, would not be reconsidered.
¶13Makari petitioned the CCPA on August 31, 1982, for a writ of mandamus. While the petition was under consideration, Maka-ri filed Application Serial No. 06/370,517 (’517) and abandoned the ’469 application. The ’517 application is a continuation-in-part of the ’469 application. The CCPA dismissed the petition as moot.
¶14Makari refiled the petition to the Commissioner in the ’517 application on July 27, 1982. That petition is substantively identical with the August 31, 1981 petition.
¶15On February 1, 1983, all claims of the ’517 application were rejected under 35 U.S.C. § 103 in view of the Makari August 9,1959 publication.
¶16On March 23, 1983, Assistant Commissioner Tegtmeyer denied Makari’s July 27, 1982 petition, observing that the 1982 Petition was identical to the 1981 Petition and saying “the decision on . . . [the 1981 Petition] dated January 29,1982 remains appropriate and is incorporated herein by reference.”
¶17II.
¶18Our jurisdiction in relation to the Patent and Trademark Office is limited to review of decisions of boards established in that Office. We do not have jurisdiction to review decisions of the Commissioner on petitions. In re Wiechert, 54 CCPA 957, 969-70, 370 F.2d 927, 938, 152 USPQ 247, 255 (1967).
¶19Under 28 U.S.C. § 1651(a),5 the All Writs Act, this court may issue a writ to rectify an action that would otherwise frustrate our prospective jurisdiction. Margolis v. Banner, 599 F.2d 435, 440-41, 202 USPQ 365, 371 (Cust. & Pat.App.1979). Makari’s reliance on Margolis is misplaced.
¶20In Margolis, the examiner alleged that petitioners’ application and another, commonly-assigned application of different in-ventorship contained conflicting claims, and required that the assignee: (1) name the prior inventor; and (2) limit the claims of the other application. On petition, the Deputy Assistant Commissioner ruled that petitioners’ application was abandoned for failure to comply with the examiner’s requirement.
¶21On petition for a writ of mandamus, the court issued a writ to preserve its prospective appellate jurisdiction:
The examiner’s demands, under threat of abandonment, that petitioners do more than they did amounted to a de facto rejection of petitioners’ claims. The subsequent ruling of abandonment by the Deputy Assistant Commissioner, precluding petitioners from an appeal to the Board of Appeals from the de facto rejection, clearly had the effect of frustrating this court’s prospective appellate jurisdiction over an appeal from a decision of the Board of Appeals [Footnote and citations omitted]. Id. at 443, 202 USPQ at 372-73.
¶22Here, issuance of the requested writ is not necessary or appropriate to aid or preserve our prospective appellate jurisdiction over an appeal from a decision of the board on the ’517 application. All of the claims of that application stand rejected under 35 U.S.C. § 103. If the board affirms the rejection in whole or in part, Makari may appeal that decision to this court under 35 U.S.C. § 141.
¶23Focusing on subject matter common to his 1958 publication and the ’517 application, Makari argues:
If petitioner here is denied the August 4, 1959 filing date, his own publication becomes a statutory bar which will prevent the Board of Appeals (and the CAFC) from considering the patentability of those claims which “read on” his publication.
¶24*712If it were otherwise appropriate (a question we need not decide), the argument is here inapt. There are no claims in the ’517 application rejected because they “read on” the 1958 publication. The basis of the rejection is 35 U.S.C. § 103, not § 102.
¶25The petition is dismissed for lack of jurisdiction over the Commissioner’s decisions on petitions and on the absence of a basis for application of the All Writs Act.6
