1402 Grounds for Filing [R-2] - 1400 Correction of Patents


1402 Grounds for Filing [R-2]

A reissue application is filed to correct an error in the patent which was made without any deceptive intention, where, as a result of the error, the patent is deemed wholly or partly inoperative or invalid. An error in the patent arises out of an error in conduct which was made in the preparation and/or prosecution of the application which became the patent.

There must be at least one error in the patent to provide grounds for reissue of the patent. If there is no error in the patent, the patent will not be reissued. The present section provides a discussion of what may be considered an error in the patent upon which to base a reissue application.

In accordance with 35 U.S.C. 251, the error upon which a reissue is based must be one which causes the patent to be "deemed wholly or partly inoperative or invalid, by reason of a defective specification or drawing, or by reason of the patentee claiming more or less than he had a right to claim in the patent." Thus, an error under 35 U.S.C. 251 has not been presented where the correction to the patent is one of spelling, or grammar, or a typographical, editorial or clerical error which does not cause the patent to be deemed wholly or partly inoperative or invalid for the reasons specified in 35 U.S.C. 251. These corrections to a patent do not provide a basis for reissue (although these corrections may also be included in a reissue application, where a 35 U.S.C. 251 error is already present).

These corrections may be made via a certificate of correction; see MPEP § 1481.

The most common bases for filing a reissue application are:

(A) the claims are too narrow or too broad;

(B) the disclosure contains inaccuracies;

(C) applicant failed to or incorrectly claimed foreign priority; and

(D) applicant failed to make reference to or incorrectly made reference to prior copending applications.

An attorney's failure to appreciate the full scope of the invention was held to be an error correctable through reissue in >the decision of< In re Wilder, 736 F.2d 1516, 222 USPQ 369 (Fed. Cir. 1984). The correction of misjoinder of inventors in divisional reissues has been held to be a ground for reissue. See Ex parte Scudder, 169 USPQ 814 (Bd. App. 1971).The Board of Appeals held in Ex parte Scudder, 169 USPQ at 815, that 35 U.S.C. 251 authorizes reissue application to correct misjoinder of inventors where 35 U.S.C. 256 is inadequate.

Reissue may no longer be necessary under the facts in Ex parte Scudder, supra, in view of 35 U.S.C. 116 which provides, inter alia, that:

"Inventors may apply for a patent jointly even though . . . (3) each did not make a contribution to the subject matter of every claim in the patent."

See also 37 CFR 1.45(b)(3).

If the only change being made in the patent is correction of the inventorship, this can be accomplished by filing a request for a certificate of correction under the provisions of 35 U.S.C. 256 and 37 CFR 1.324. See MPEP §  1412.04 and § 1481. A Certificate of Correction will be issued if all parties are in agreement and the inventorship issue is not contested.

A reissue was granted in Brenner v. State of Israel, 400 F.2d 789, 158 USPQ 584 (D.C. Cir. 1968), where the only ground urged was failure to file a certified copy of the original foreign application to obtain the right of foreign priority under 35 U.S.C. 119(a)-(d) before the patent was granted.

In Brenner, the claim for priority had been made in the prosecution of the original patent, and it was only necessary to submit a certified copy of the priority document in the reissue application to perfect priority. >Reissue is also available to convert the "error" in failing to take any steps to obtain the right of foreign priority under 35 U.S.C. 119(a)-(d) before the patent was granted.< In a situation where it is necessary to submit for the first time both the claim for priority and the certified copy of the priority document in the reissue application, ** >and the patent to be reissued resulted from a< utility or plant application which became the patent to be reissued was filed on or after November 29, 2000, the reissue applicant ** >must (where it is necessary to submit for the first time the claim for priority) also< file a petition for an unintentionally delayed priority claim under 37 CFR 1.55(c) in addition to filing a reissue application. See MPEP § 201.14(a).

The courts have not addressed the question of correction of the failure to adequately claim * >benefit< under 35 U.S.C. 119(e) in the application (which became the patent to be reissued) via reissue. If the application which became the patent to be reissued was filed prior to November 29, 2000, correction as to * >benefit< under 35 U.S.C. 119(e) would be permitted in a manner somewhat analogous to that of the priority correction discussed above. Under no circumstances, however, can a reissue be employed to correct an applicant's mistake by adding or correcting a * >benefit< claim under 35 U.S.C. 119(e) where the application, which became the patent to be reissued, was filed on or after November 29, 2000.

Section 4503 of the American Inventors Protection Act of 1999 (AIPA) amended 35 U.S.C. 119(e)(1) to state that:

No application shall be entitled to the benefit of an earlier filed provisional application under this subsection unless an amendment containing the specific reference to the earlier filed provisional application is submitted at such time during the pendency of the application as required by the Director. The Director may consider the failure to submit such an amendment within that time period as a waiver of any benefit under this subsection. The Director may establish procedures, including the payment of a surcharge, to accept an unintentionally delayed submission of an amendment under this section during the pendency of the application.

35 U.S.C. 119(e)(1), as amended by the AIPA, clearly prohibits the addition or correction of * >benefit< claims under 35 U.S.C. 119(e) when the application is no longer pending, e.g., an issued patent. Therefore, a reissue is not a valid mechanism for adding or correcting a * >benefit< claim under 35 U.S.C. 119(e) after a patent has been granted.

>Correction of failure to adequately claim priority under 35 U.S.C. 120 in an earlier filed copending U.S. Patent application was held a proper ground for reissue. Sampson v. Comm'r Pat., 195 USPQ 136, 137 (D.D.C. 1976). If the utility or plant application which became the patent to be reissued was filed on or after November 29, 2000, the reissue applicant must file a petition for an unintentionally delayed priority claim under 37 CFR 1.78(a)(3) and (a)(6) in addition to filing a reissue application. See MPEP § 201.11. For treatment of an error involving disclaimer of a priority claim under 35 U.S.C. 120, see MPEP 1405.<

A reissue applicant's failure to timely file a divisional application >covering the non-elected invention(s) following a restriction requirement< is not considered to be error causing a patent granted on elected claims to be partially inoperative by reason of claiming less than the applicant had a right to claim. Thus, such applicant's error is not correctable by reissue of the original patent under 35 U.S.C. 251. ** >See MPEP § 1412.01.

A reissue may be based on a drawing correction that is substantive in nature, because such a correction qualifies as correcting an "error" under 35 U.S.C. 251 that may properly be deemed to render the patent wholly or partly inoperative. A reissue application cannot be based on a non-substantive drawing change, such as a reference numeral correction or addition, the addition of shading, or even the addition of an additional figure merely to "clarify" the disclosure. Non-substantive drawing changes may, however, be included in a reissue application that corrects at least one substantive "error " under 35 U.S.C. 251.<
