Patent owners may amend their patents but cannot broaden claim scope or introduce new matter.

Amendments to the patent (one which has not expired) may be filed by the patent owner with the request under 35 U.S.C. 302. See MPEP § 2221. Such amendments, however, may not enlarge the scope of a claim of the patent or introduce new matter. Amended or new claims which broaden or enlarge the scope of a claim of the patent should be rejected under 35 U.S.C. 305. The test for when an amended or “new claim enlarges the scope of an original claim under 35 U.S.C. 305 is the same as that under the 2-year limitation for reissue applications adding enlarging claims under 35 U.S.C. 251, last paragraph.” In re Freeman, 30 F.3d 1459, 1464, 31 USPQ2d 1444, 1447 (Fed. Cir. 1994). See MPEP § 2258 for a discussion of enlargement of claim scope. For handling of new matter, see MPEP § 2270. Amendments proposed in a reexamination will normally be entered and be considered to be entered for purposes of prosecution before the Office (if they are timely and comply with the rules); however, the amendments do not become effective in the patent until the reexamination certificate under 35 U.S.C. 307 is issued and published.

Amendments Must Follow Initial Request Date
Note:
All amendments to the patent during reexamination must be based on the specification as of when the reexamination request was filed.

When a reexamination certificate is printed, all underlined matter is printed in italics and all brackets are printed as they were inserted in the proceeding in order to thereby show exactly which additions and deletions have been made in the patent via the reexamination proceeding. In accordance with 37 CFR 1.530(i), all amendments to the patent being reexamined must be made relative to the patent specification in effect as of the date of the filing of the request for reexamination. The patent specification includes the claims and drawings. If there was a prior change to the patent (made via a concluded post-patent proceeding, e.g., prior reexamination certificate, reissue of the patent, certificate of correction, PTAB trial certificate, etc.), the first amendment must be made relative to the patent specification as changed by the prior proceeding or other mechanism for changing the patent. All amendments subsequent to the first amendment must also be made relative to the patent specification in effect as of the date of the filing of the request for reexamination, and not relative to the prior amendment. In those rare instances where a concluded post-patent proceeding changes the patent while the reexamination proceeding is pending, amendments will be made relative to the patent, as revised by the concluded proceeding, and 37 CFR 1.530(i) is waived to that extent.

Second Claim Amendment Must Include Previous Changes and New Additions
Note:
The second amendment must include all changes from previous amendments as well as new additions, without showing deletions or unchanged text.
(F) Amendment of Original Patent Claims More Than Once. The following example illustrates proper claim amendment of original patent claims in reexamination proceedings, where more than one amendment to a claim is made: Note that the second amendment must include (1) the changes previously presented in the first amendment; i.e., [cutting means] knife, as well as (2) the new changes presented in the second amendment; i.e., serrated. The word bone was presented in the first amendment and is now to be deleted in the second amendment. Thus, “bone” is NOT to be shown in brackets in the second amendment. Rather, the word “bone” is simply omitted from the claim, since “bone” never appeared in the patent. The word notched which was presented in the first amendment is replaced by the word serrated in the second amendment. The word notched is being deleted in the second amendment and did not appear in the patent; accordingly, “notched” is not shown in any form in the claim. The word serrated is being added in the second amendment, and accordingly, “serrated” is added to the claim and is underlined. It should be understood that in the second amendment, the deletions of “notched” and “bone” are not changes from the original patent claim text and therefore, are not shown in the second amendment. In both the first and the second amendments, the entire claim is presented only with the changes from the original patent text. If the patent expires during an ex parte or inter partes reexamination proceeding and the patent claims have been amended in that reexamination proceeding, the Office will hold the amendments as being improper, and all subsequent reexamination will be on the basis of the unamended patent claims. This procedure is necessary since no amendments will be incorporated into the patent by certificate after the expiration of the patent.
  • (1) Patent claim. Claim 1. A cutting means having a handle portion and a blade portion.
  • (2) Proper first amendment format. Claim 1. (amended), A [cutting means] knife having a bone handle portion and a notched blade portion.

Status Identifier Requirement for Proposed Amendments
Note:
Examiners may accept proposed amendments even if the status identifier used does not match those recommended by 37 CFR 1.530(d)(2) or 1.121(c).
A substantial number of problems arise in the Office because of improper submission of proposed amendments in reexamination proceedings. The following examples are provided to assist in the preparation of proper proposed amendments in reexamination proceedings. In regard to status identifiers, examiners may accept an amendment even if the status identifier used is not a status identifier recommended by 37 CFR 1.530(d)(2) or 1.121(c).
  • (A) Original Patent Description or Patent Claim Amended.
    • (1) Specification – submit a copy of the entire paragraph (of the specification of the patent) being amended with underlining and bracketing. Thus, the amendment would be presented as follows: Replace the paragraph beginning at column 4, line 23 with the following: Scanning [is] are controlled by clocks which are, in turn, controlled from the display tube line synchronization. The signals resulting from scanning the scope of the character are delivered in parallel, then converted into serial mode through a shift register, wherein the shift signal frequency is controlled by a clock that is controlled from the display tube line synchronization.
    • (2) Claims – for changes to the patent claims, one must submit a copy of the entire patent claim with the amendments shown by underlining and single bracketing. Thus, the amendment would be presented as follows: Amend claim 6 as follows: Claim 6. (amended), The apparatus of claim [5] 1 wherein the [first] second piezoelectric element is parallel to the [second] third piezoelectric element. If the dependency of any original patent claim is to be changed by amendment, it is proper to make that original patent claim dependent upon a later filed higher numbered claim.
  • (B) Cancellation of Entire Claim(s).
    • (1) Original patent claim canceled – in writing, direct cancellation of the entire patent claim. Cancel claim 6.
    • (2) Proposed new claim (previously added in the reexamination) canceled – in writing, direct cancellation of the entire claim. Cancel claim 15.
  • (C) Re-presentation of Original Patent Claims (no underlining or bracketing). Amend claim 4 to read as original patent claim 4: Claim 4. The apparatus of claim 1 wherein the first piezoelectric element is perpendicular to the second piezoelectric element.
  • (D) Presentation of New Claims. Each proposed new claim (i.e., a claim not found in the patent, that is newly presented in the reexamination proceeding) should be presented with underlining throughout the claim, including the claim number. The status identifier “(new)” may or may not be underlined. Examiners may accept an amendment even if the claim number is not underlined or the status identifier(s) used is not a status identifier recommended by 37 CFR 1.530(d)(2) or 1.121(c). The following is an example of a presentation of a new claim: Insert new claim 7 as follows: Claim 7 (New). The apparatus of claim 5 further comprising electrodes attaching to said opposite faces of the second and third piezoelectric elements. Even though an original claim may have been canceled, the numbering of the original claims does not change. Accordingly, any added claims are numbered beginning with the next higher number than the number of claims in the original patent. If new claims have been added to the reexamination proceeding which are later canceled prior to the issuance of the reexamination certificate, the examiner will renumber, at the time of preparing the NIRC for subsequent issuance of the certificate, any remaining new claims in numerical order to follow the highest number of the claims in the original patent. A claim number previously assigned to a new claim that has been canceled should not be reassigned to a different new claim during the reexamination proceeding. For example, if new claim 5 added in a prior amendment is canceled in a later amendment, a different new claim added in a later amendment during the reexamination proceeding would be claim 6. Of course, at the time of preparing the NIRC, claim 6 would be renumbered for issue of the reexamination certificate as claim 5.
  • (E) Amendment of New Claims. An amendment of a new claim (i.e., a claim not found in the patent, that was previously presented in the reexamination proceeding) must present the entire text of the new claim containing the amendatory material, and it must be underlined throughout the claim, including the claim number. The status identifier(s) may or may not be underlined. Examiners may accept an amendment even if the claim number is not underlined or the status identifier(s) used is not a status identifier recommended by 37 CFR 1.530(d)(2) or 1.121(c). The presentation cannot contain any bracketing or other indication of what was in the previous version of the claim. This is because all changes in the reexamination are made vis-a-vis the original patent, and not in comparison with any prior amendment. Although the presentation of the amended claim does not contain any indication of what is changed from a previous version of the claim, patent owner must point out what is changed, in the “Remarks” portion of the amendment. Also, as per 37 CFR 1.530(e), each change made in the claim must be accompanied by an explanation of the support in the disclosure of the patent (i.e., the reexamination specification) for the change. The following is one example to illustrate a proper amendment of a new claim: First Amendment (wherein claim 11 was first presented): Claim 11 (New). A knife comprising a handle portion and a notched blade portion. In the Remarks (supplied on a separate page): Status: The present application includes pending claims 1-11, with claims 1 and 11 being independent. With this amendment, applicant has added new independent claim 11. Support for this new claim is found in column 4, lines 26-41, column 5, lines 3-18, and column 6, lines 5-15. Second Amendment (wherein claim 11 is amended): Claim 11 (New, amended). A fishing knife comprising a bone handle portion and a notched blade portion. In the Remarks (supplied on a separate page): Status: The present application includes pending claims 1-11, with claims 1 and 11 being independent. With this amendment, applicant has amended new independent claim 11 as described below. Claim 11: Claim 11 is amended to add “fishing” before “knife” and “bone” before “handle.” Support for these changes is found in column 4, lines 34-41 and column 6, lines 5-8, respectively.
  • (F) Amendment of Original Patent Claims More Than Once. The following example illustrates proper claim amendment of original patent claims in reexamination proceedings, where more than one amendment to a claim is made: Note that the second amendment must include (1) the changes previously presented in the first amendment; i.e., [cutting means] knife, as well as (2) the new changes presented in the second amendment; i.e., serrated. The word bone was presented in the first amendment and is now to be deleted in the second amendment. Thus, “bone” is NOT to be shown in brackets in the second amendment. Rather, the word “bone” is simply omitted from the claim, since “bone” never appeared in the patent. The word notched which was presented in the first amendment is replaced by the word serrated in the second amendment. The word notched is being deleted in the second amendment and did not appear in the patent; accordingly, “notched” is not shown in any form in the claim. The word serrated is being added in the second amendment, and accordingly, “serrated” is added to the claim and is underlined. It should be understood that in the second amendment, the deletions of “notched” and “bone” are not changes from the original patent claim text and therefore, are not shown in the second amendment. In both the first and the second amendments, the entire claim is presented only with the changes from the original patent text. If the patent expires during an ex parte or inter partes reexamination proceeding and the patent claims have been amended in that reexamination proceeding, the Office will hold the amendments as being improper, and all subsequent reexamination will be on the basis of the unamended patent claims. This procedure is necessary since no amendments will be incorporated into the patent by certificate after the expiration of the patent.
    • (1) Patent claim. Claim 1. A cutting means having a handle portion and a blade portion.
    • (2) Proper first amendment format. Claim 1. (amended), A [cutting means] knife having a bone handle portion and a notched blade portion.
    • (3) Proper second amendment format. Claim 1. (twice amended), A [cutting means] knife having a handle portion and a serrated blade portion.
  • (A) For clerical handling of amendments, see MPEP § 2270 for ex parte reexamination proceedings, and see MPEP § 2670 for inter partes reexamination proceedings.
  • (B) As to amendments in a merged proceeding, see MPEP § 2283 for an ex parte reexamination merged with another ex parte reexamination and MPEP § 2285 for an ex parte reexamination merged with a reissue application. If an inter partes reexamination proceeding is included in the merger, see MPEP § 2686.01 and § 2686.03.
  • (C) As to amendments in a pending reexamination proceeding where a reexamination certificate has issued for the patent based on a prior concluded reexamination, pursuant to MPEP § 2295, any amendment made in the pending reexamination proceeding must be presented as if the changes made to the patent text via the reexamination certificate (for the prior concluded reexamination) are a part of the original patent. All italicized text of the certificate is considered as if the text was present without italics in the original patent. Further, any text of the reexamination certificate found in brackets is considered as if it were never present in the patent at all. Thus, for making an amendment in the pending reexamination, all italicized text of the reexamination certificate is presented in the amendment without italics. Further, any text found in brackets in the reexamination certificate is omitted in the amendment.
  • (D) As to amendments in a pending reexamination proceeding where a reissue patent has been granted, pursuant to MPEP § 2285, subsection II.A., an amendment in a reexamination of a reissued patent is made the same way as in a reexamination of a reexamined patent (i.e., as per MPEP § 2295). Thus, all italicized text of the reissue patent is presented in the amendment (made in the pending reexamination proceeding) without italics. Further, any text found in brackets in the reissue patent is omitted in the amendment (made in the pending reexamination proceeding).
  • (E) As to amendments in a pending reexamination proceeding where a PTAB trial certificate has issued for the patent under reexamination, an amendment must be presented as if the changes made to the patent via the PTAB trial certificate are a part of the original patent.

How Reexamination Certificate Shows Additions and Deletions
Note:
The reexamination certificate must show additions and deletions by printing underlined matter in italics and retaining original brackets.

When a reexamination certificate is printed, all underlined matter is printed in italics and all brackets are printed as they were inserted in the proceeding in order to thereby show exactly which additions and deletions have been made in the patent via the reexamination proceeding. In accordance with 37 CFR 1.530(i), all amendments to the patent being reexamined must be made relative to the patent specification in effect as of the date of the filing of the request for reexamination. The patent specification includes the claims and drawings. If there was a prior change to the patent (made via a concluded post-patent proceeding, e.g., prior reexamination certificate, reissue of the patent, certificate of correction, PTAB trial certificate, etc.), the first amendment must be made relative to the patent specification as changed by the prior proceeding or other mechanism for changing the patent. All amendments subsequent to the first amendment must also be made relative to the patent specification in effect as of the date of the filing of the request for reexamination, and not relative to the prior amendment. In those rare instances where a concluded post-patent proceeding changes the patent while the reexamination proceeding is pending, amendments will be made relative to the patent, as revised by the concluded proceeding, and 37 CFR 1.530(i) is waived to that extent.

No Amendments After Patent Expiration During Reexamination
Note:
This rule requires that no amendments be incorporated into a patent by a certificate after the patent has expired, especially during reexamination proceedings.

Pursuant to 37 CFR 1.530(j), “[n]o amendment may be proposed for entry in an expired patent.” Thus, if a patent expires during the pendency of a reexamination proceeding for a patent, all amendments to the patent claims and all claims added during the proceeding are withdrawn. The patent owner should be notified of this in the next Office action. The Office action will hold the amendments to be improper, and state that all subsequent reexamination will be on the basis of the unamended patent claims. This procedure is necessary since no amendments will be incorporated into the patent by a certificate after the expiration of the patent.

The word bone was presented in the first amendment and is now to be deleted in the second amendment. Thus, “bone” is NOT to be shown in brackets in the second amendment. Rather, the word “bone” is simply omitted from the claim, since “bone” never appeared in the patent. The word notched which was presented in the first amendment is replaced by the word serrated in the second amendment. The word notched is being deleted in the second amendment and did not appear in the patent; accordingly, “notched” is not shown in any form in the claim. The word serrated is being added in the second amendment, and accordingly, “serrated” is added to the claim and is underlined. It should be understood that in the second amendment, the deletions of “notched” and “bone” are not changes from the original patent claim text and therefore, are not shown in the second amendment. In both the first and the second amendments, the entire claim is presented only with the changes from the original patent text. If the patent expires during an ex parte or inter partes reexamination proceeding and the patent claims have been amended in that reexamination proceeding, the Office will hold the amendments as being improper, and all subsequent reexamination will be on the basis of the unamended patent claims.

Proper Claim Amendment Format for Patent Reexamination
Note:
The rule outlines how to properly amend original patent claims in reexamination proceedings, requiring the inclusion of all previous changes and new additions while omitting deleted terms that never appeared in the original patent.

A substantial number of problems arise in the Office because of improper submission of proposed amendments in reexamination proceedings. The following examples are provided to assist in the preparation of proper proposed amendments in reexamination proceedings. In regard to status identifiers, examiners may accept an amendment even if the status identifier used is not a status identifier recommended by 37 CFR 1.530(d)(2) or 1.121(c).
(F) Amendment of Original Patent Claims More Than Once. The following example illustrates proper claim amendment of original patent claims in reexamination proceedings, where more than one amendment to a claim is made: Note that the second amendment must include (1) the changes previously presented in the first amendment; i.e., [cutting means] knife, as well as (2) the new changes presented in the second amendment; i.e., serrated. The word bone was presented in the first amendment and is now to be deleted in the second amendment. Thus, “bone” is NOT to be shown in brackets in the second amendment. Rather, the word “bone” is simply omitted from the claim, since “bone” never appeared in the patent. The word notched which was presented in the first amendment is replaced by the word serrated in the second amendment. The word notched is being deleted in the second amendment and did not appear in the patent; accordingly, “notched” is not shown in any form in the claim. The word serrated is being added in the second amendment, and accordingly, “serrated” is added to the claim and is underlined. It should be understood that in the second amendment, the deletions of “notched” and “bone” are not changes from the original patent claim text and therefore, are not shown in the second amendment. In both the first and the second amendments, the entire claim is presented only with the changes from the original patent text. If the patent expires during an ex parte or inter partes reexamination proceeding and the patent claims have been amended in that reexamination proceeding, the Office will hold the amendments as being improper, and all subsequent reexamination will be on the basis of the unamended patent claims. This procedure is necessary since no amendments will be incorporated into the patent by certificate after the expiration of the patent.

(2) Proper first amendment format.

Amended Claim Must Not Enlarge Original Scope
Note:
An amended claim must not broaden the scope of an original claim under 35 U.S.C. 305, aligning with the 2-year limitation for reissue applications adding enlarging claims under 35 U.S.C. 251.

Amendments to the patent (one which has not expired) may be filed by the patent owner with the request under 35 U.S.C. 302. See MPEP § 2221. Such amendments, however, may not enlarge the scope of a claim of the patent or introduce new matter. Amended or new claims which broaden or enlarge the scope of a claim of the patent should be rejected under 35 U.S.C. 305. The test for when an amended or “new claim enlarges the scope of an original claim under 35 U.S.C. 305 is the same as that under the 2-year limitation for reissue applications adding enlarging claims under 35 U.S.C. 251, last paragraph.” In re Freeman, 30 F.3d 1459, 1464, 31 USPQ2d 1444, 1447 (Fed. Cir. 1994). See MPEP § 2258 for a discussion of enlargement of claim scope. For handling of new matter, see MPEP § 2270. Amendments proposed in a reexamination will normally be entered and be considered to be entered for purposes of prosecution before the Office (if they are timely and comply with the rules); however, the amendments do not become effective in the patent until the reexamination certificate under 35 U.S.C. 307 is issued and published.

Determining Patent Expiration Date
Note:

No amendment will be permitted where the certificate issues after expiration of the patent. See 37 CFR 1.530(d)(3). The patent expiration date for a utility patent, for example, is determined by taking into account the term of the patent, whether maintenance fees have been paid for the patent, whether any disclaimer was filed as to the patent to shorten its term, any patent term extensions or adjustments for delays within the USPTO under 35 U.S.C. 154 (see MPEP § 2710 et seq.), and any patent term extensions under 35 U.S.C. 156 for premarket regulatory review (see MPEP § 2750 et seq.).

(A) Original Patent Description or Patent Claim Amended. (1) Specification – submit a copy of the entire paragraph (of the specification of the patent) being amended with underlining and bracketing. Thus, the amendment would be presented as follows: Replace the paragraph beginning at column 4, line 23 with the following: Scanning [is] are controlled by clocks which are, in turn, controlled from the display tube line synchronization. The signals resulting from scanning the scope of the character are delivered in parallel, then converted into serial mode through a shift register, wherein the shift signal frequency is controlled by a clock that is controlled from the display tube line synchronization.

Amendments Prohibited After Patent Expires
Note:
No changes can be made to a patent after its expiration date.

No amendment will be permitted where the certificate issues after expiration of the patent. See 37 CFR 1.530(d)(3). The patent expiration date for a utility patent, for example, is determined by taking into account the term of the patent, whether maintenance fees have been paid for the patent, whether any disclaimer was filed as to the patent to shorten its term, any patent term extensions or adjustments for delays within the USPTO under 35 U.S.C. 154 (see MPEP § 2710 et seq.), and any patent term extensions under 35 U.S.C. 156 for premarket regulatory review (see MPEP § 2750 et seq.).

Amendments Withdrawn After Patent Expiration During Reexamination
Note:
If a patent expires during reexamination, all amendments and added claims are withdrawn. The Office action will notify the patent owner and proceed based on unamended claims.

Pursuant to 37 CFR 1.530(j), “[n]o amendment may be proposed for entry in an expired patent.” Thus, if a patent expires during the pendency of a reexamination proceeding for a patent, all amendments to the patent claims and all claims added during the proceeding are withdrawn. The patent owner should be notified of this in the next Office action. The Office action will hold the amendments to be improper, and state that all subsequent reexamination will be on the basis of the unamended patent claims. This procedure is necessary since no amendments will be incorporated into the patent by a certificate after the expiration of the patent.

Examiner Form Paragraphs

Examiner form paragraphs are standard language that you might see in an Office Action or communication from the USPTO. Examiners have latitude to change the form paragraphs, but you will often see this exact language.

¶ 22.12 ¶ 22.12 Amendments Proposed in a Reexamination – 37 CFR 1.530(d)-(j)

Patent owner is notified that any proposed amendment to the specification and/or claims in this reexamination proceeding must comply with 37 CFR 1.530(d)-(j) , must be formally presented pursuant to 37 CFR 1.52(a) and (b) , and must contain any fees required by 37 CFR 1.20(c) .

Examiner Note

This paragraph may be used in the order granting reexamination and/or in the first Office action to advise patent owner of the proper manner of making amendments in a reexamination proceeding.

¶ 22.13 ¶ 22.13 Improper Amendment in an Ex Parte Reexamination – 37 CFR 1.530(d)-(j)

The amendment filed [1] proposes amendments to [2] that do not comply with 37 CFR 1.530(d)-(j) , which sets forth the manner of making amendments in reexamination proceedings. A supplemental paper correctly proposing amendments in the present ex parte reexamination proceeding is required.

A shortened statutory period for response to this letter is set to expire [3] from the mailing date of this letter. If patent owner fails to timely correct this informality, the amendment will be held not to be an appropriate response, prosecution of the present ex parte reexamination proceeding will be terminated, and a reexamination certificate will issue. 37 CFR 1.550(d) .
