1490 Disclaimers [R-7] - 1400 Correction of Patents

1490 Disclaimers [R-7]

35 U.S.C. 253 Disclaimer.

Whenever, without any deceptive intention, a claim of a patent is invalid the remaining claims shall not thereby be rendered invalid. A patentee, whether of the whole or any sectional interest therein, may, on payment of the fee required by law, make disclaimer of any complete claim, stating therein the extent of his interest in such patent. Such disclaimer shall be in writing, and recorded in the Patent and Trademark Office; and it shall thereafter be considered as part of the original patent to the extent of the interest possessed by the disclaimant and by those claiming under him.

In like manner any patentee or applicant may disclaim or dedicate to the public the entire term, or any terminal part of the term, of the patent granted or to be granted.


37 CFR 1.321 Statutory disclaimers, including terminal disclaimers.

(a) A patentee owning the whole or any sectional interest in a patent may disclaim any complete claim or claims in a patent. In like manner any patentee may disclaim or dedicate to the public the entire term, or any terminal part of the term, of the patent granted. Such disclaimer is binding upon the grantee and its successors or assigns. A notice of the disclaimer is published in the Official Gazette and attached to the printed copies of the specification. The disclaimer, to be recorded in the Patent and Trademark Office, must:

(1) be signed by the patentee, or an attorney or agent of record;

(2) identify the patent and complete claim or claims, or term being disclaimed. A disclaimer which is not a disclaimer of a complete claim or claims, or term, will be refused recordation;

(3) state the present extent of patentee's ownership interest in the patent; and

(4) be accompanied by the fee set forth in § 1.20(d).

(b) An applicant or assignee may disclaim or dedicate to the public the entire term, or any terminal part of the term, of a patent to be granted. Such terminal disclaimer is binding upon the grantee and its successors or assigns. The terminal disclaimer, to be recorded in the Patent and Trademark Office, must:

(1) be signed:

(i) by the applicant, or

(ii) if there is an assignee of record of an undivided part interest, by the applicant and such assignee, or

(iii) if there is an assignee of record of the entire interest, by such assignee, or

(iv) by an attorney or agent of record;

(2) specify the portion of the term of the patent being disclaimed;

(3) state the present extent of applicant's or assignee's ownership interest in the patent to be granted; and

(4) be accompanied by the fee set forth in § 1.20(d).

(c) A terminal disclaimer, when filed to obviate judicially created double patenting in a patent application or in a reexamination proceeding except as provided for in paragraph (d) of this section, must:

(1) Comply with the provisions of paragraphs (b)(2) through (b)(4) of this section;

(2) Be signed in accordance with paragraph (b)(1) of this section if filed in a patent application or in accordance with paragraph (a)(1) of this section if filed in a reexamination proceeding; and

(3) Include a provision that any patent granted on that application or any patent subject to the reexamination proceeding shall be enforceable only for and during such period that said patent is commonly owned with the application or patent which formed the basis for the judicially created double patenting.

(d) A terminal disclaimer, when filed in a patent application or in a reexamination proceeding to obviate double patenting based upon a patent or application that is not commonly owned but was disqualified under 35 U.S.C. 103(c) as resulting from activities undertaken within the scope of a joint research agreement, must:

(1) Comply with the provisions of paragraphs (b)(2) through (b)(4) of this section;

(2) Be signed in accordance with paragraph (b)(1) of this section if filed in a patent application or be signed in accordance with paragraph (a)(1) of this section if filed in a reexamination proceeding;

(3) Include a provision waiving the right to separately enforce any patent granted on that application or any patent subject to the reexamination proceeding and the patent or any patent granted on the application which formed the basis for the double patenting, and that any patent granted on that application or any patent subject to the reexamination proceeding shall be enforceable only for and during such period that said patent and the patent, or any patent granted on the application, which formed the basis for the double patenting are not separately enforced.


A disclaimer is a statement filed by an owner (in part or in entirety) of a patent or of a patent to be granted (i.e., an application), in which said owner relinquishes certain legal rights to the patent. There are two types of disclaimers: a statutory disclaimer and a terminal disclaimer. The owner of a patent or an application is the original inventor(s) or the assignee of the original inventor(s). The patent or application is assigned by one assignment or by multiple assignments which establish a chain of title from the inventor(s) to the assignee(s). The owner of the patent or application can sign a disclaimer, and a person empowered by the owner to sign the disclaimer can also sign it. Per 37 CFR 1.321(b)(1)(iv), an attorney or agent of record is permitted to sign the disclaimer. A registered practitioner acting in a representative capacity under 37 CFR 1.34 is not permitted to sign the disclaimer. For a disclaimer to be accepted, it must be signed by the proper party as follows:

(A) A disclaimer filed in an application must be signed by

(1) the applicant where the application has not been assigned,

(2) the applicant and the assignee where each owns a part interest in the application,

(3) the assignee where assignee owns the entire interest in the application, or

(4) an attorney or agent of record.

(B) A disclaimer filed in a patent or a reexamination proceeding must be signed by either

(1) the patentee (the assignee, the inventor(s) if the patent is not assigned, or the assignee and the inventors if the patent is assigned-in-part), or

(2) an attorney or agent of record.

(C) Where the assignee (of an application or of a patent being reexamined or to be reissued) signs the disclaimer, there is a requirement to comply with 37 CFR 3.73(b) in order to satisfy 37 CFR 1.321, unless an attorney or agent of record signs the disclaimer. In order to comply with 37 CFR 3.73(b), the assignee's ownership interest must be established by:

(1) filing in the application or patent evidence of a chain of title from the original owner to the assignee and a statement affirming that the documentary evidence of the chain of title from the original owner to the assignee was, or concurrently is being, submitted for recordation pursuant to 37 CFR 3.11, or

(2) specifying in the record of the application or patent where such evidence is recorded in the Office (e.g., reel and frame number, etc.). The submission with respect to 37 CFR 3.73(b) to establish ownership must be signed by a party authorized to act on behalf of the assignee. See also MPEP § 324 as to compliance with 37 CFR 3.73(b). A copy of the "Statement Under 37 CFR 3.73 (b)," which is reproduced in MPEP § 324, may be sent by the examiner to applicant to provide an acceptable way to comply with the requirements of 37 CFR 3.73 (b).

(D) Where the attorney or agent of record signs the disclaimer, there is no need to comply with 37 CFR 3.73(b).

(E) The signature on the disclaimer need not be an original signature. Pursuant to 37 CFR 1.4(d)(1)(ii), the submitted disclaimer can be a copy, such as a photocopy or facsimile transmission of an original disclaimer.

I.    STATUTORY DISCLAIMERS

Under 37 CFR 1.321(a) the owner of a patent may disclaim a complete claim or claims of his or her patent. This may result from a lawsuit or because he or she has reason to believe that the claim or claims are too broad or otherwise invalid. If the patent is involved in an interference, see 37 CFR 41.121(a).

As noted above, a statutory disclaimer is a statement in which a patent owner relinquishes legal rights to one or more claims of a patent. A statutory disclaimer is not, however, a vehicle for adding or amending claims, *>because< there is no provision for such in the statute (35 U.S.C. 253) nor the rules (37 CFR 1.321). Thus, claims of a patent cannot be disclaimed in favor of new claims to be added to the patent or an amendment to existing claims.

II.    TERMINAL DISCLAIMERS

37 CFR 1.321(a) also provides for the filing by an applicant or patentee of a terminal disclaimer which disclaims or dedicates to the public the entire term or any portion of the term of a patent or patent to be granted.

37 CFR 1.321(c) specifically provides for the filing of a terminal disclaimer in an application or a reexamination proceeding for the purpose of overcoming a nonstatutory double patenting rejection. See MPEP § 804.02.

37 CFR 1.321(d) specifically provides for the filing of a terminal disclaimer in an application or a reexamination proceeding for the purpose of overcoming a nonstatutory double patenting rejection based on a U.S. patent or application that is not commonly owned but was disqualified under 35 U.S.C. 103(c).

III.    PROCESSING

Certificate of Correction Branch

The Certificate of Correction Branch is responsible for the handling of all statutory disclaimers filed under the first paragraph of 35 U.S.C. 253, whether the case is pending or patented, and all terminal disclaimers (filed under the second paragraph of 35 U.S.C. 253) except for those filed in an application or reexamination proceeding pending in a Technology Center (TC). This involves:

(A) Determining the compliance of the disclaimer with 35 U.S.C. 253 and 37 CFR 1.321 and 3.73;

(B) Notifying applicant or patentee when the disclaimer is informal and thus not acceptable;

(C) Recording the disclaimers in the record of the application file; and

(D) Providing the disclaimer data for printing in the Official Gazette.

IV.    TERMINAL DISCLAIMER IN PENDING APPLICATION PRACTICE IN THE TECHNOLOGY CENTERS

Where a terminal disclaimer is filed in an application pending in a TC, it will be processed by the paralegal of the Office of the Special Program Examiner >or appropriate Quality Assurance Specialist (QAS)< of the TC having responsibility for the application. The paralegal will:

(A) Determine compliance with 35 U.S.C. 253 and 37 CFR 1.321 and 3.73, and ensure that the appropriate terminal disclaimer fee set forth in 37 CFR 1.20(d) is/was applied;

(B) Notify the examiner having charge of the application whether the terminal disclaimer is acceptable or not;

(C) Where the terminal disclaimer is not acceptable, indicate the nature of the informalities so that the examiner can inform applicant in the next Office action. For an IFW application, complete the IFW terminal disclaimer form by checking the "Disapproved" box and have the form scanned into IFW;

(D) Where the terminal disclaimer is acceptable, record the terminal disclaimer in the record of the application as set forth below.

The paralegal will record an acceptable terminal disclaimer as being present in an application by:

For IFW applications:

(A) Completing the IFW terminal disclaimer form by checking the "Approved" box and having the form scanned into IFW; and

(B) Entering the terminal disclaimer into PALM for the application.

**

The paralegal completes a Terminal Disclaimer Informal Memo to notify the examiner of the nature of any informalities in the terminal disclaimer. The examiner should notify the applicant of the informalities in the next Office action, or by interview with applicant if such will expedite prosecution of the application. Further, the examiner should initial and date the Terminal Disclaimer Informal Memo and return it to the paralegal to indicate that the examiner has appropriately notified applicant about the terminal disclaimer. The paralegal will then discard the Terminal Disclaimer Informal Memo.

V.    OTHER MATTERS DIRECTED TO TERMINAL DISCLAIMERS

A.    Requirements of Terminal Disclaimers

A proper terminal disclaimer must disclaim the terminal part of the statutory term of any patent granted on the application being examined which would extend beyond the expiration date of the full statutory term, shortened by any terminal disclaimer, of the patent (or of any patent granted on the application) to which the disclaimer is directed. Note the exculpatory language in the second paragraph of the sample terminal disclaimer forms, PTO/SB/25 and PTO/SB/26, provided at the end of this Chapter. That language ("In making the above disclaimer, the owner does not disclaim...") is permissible in a terminal disclaimer.

A terminal disclaimer filed to obviate a nonstatutory double patenting rejection based on a commonly owned patent or application must comply with the requirements of 37 CFR 1.321(c). The terminal disclaimer must state that any patent granted on the application being examined will be enforceable only for and during the period that it and the patent to which the disclaimer is directed or the patent granted on the application to which the disclaimer is directed are commonly owned. See MPEP § 706.02(1)(2) for examples of common ownership, or lack thereof.

A terminal disclaimer filed to obviate a nonstatutory double patenting rejection based on a non-commonly owned patent or application disqualified under 35 U.S.C. 103(c) as a result of activities undertaken within the scope of a joint research agreement under 35 U.S.C. 103(c)(2) and (3) must comply with 37 CFR 1.321(d), which sets forth signature, waiver rights and enforceability requirements.

The terminal disclaimer must include a provision:

(1) waiving the right to separately enforce (a) any patent granted on that application or the patent being reexamined and (b) the reference patent, or any patent granted on the reference application which formed the basis for the double patenting; and

(2) agreeing that any patent granted on that application or patent being reexamined shall be enforceable only for and during such period that said patent and the reference patent, or any patent granted on the reference application, which formed the basis for the double patenting are not separately enforced.

A terminal disclaimer must state that the agreement is to run with any patent granted on the application being examined and is to be binding upon the grantee, its successors, or assigns.

A statement of assignee interest in a terminal disclaimer that "A and B are the owners of 100% of the instant application..." is sufficient to satisfy the 37 CFR 1.321(b)(3) requirement that a terminal disclaimer "state the present extent of applicant's or assignee's ownership interest in the patent to be granted." Although the quoted statement does not identify what specific percentage is owned by A and what specific percentage is owned by B, the statement does provide consent to the terminal disclaimer by the entirety of the ownership of the application (A and B own all of the invention, regardless of the individual percentages they own).

The appropriate one of form paragraphs 14.27.04 to 14.27.08 (reproduced below) may be used to provide applicant or patent owner with an example of acceptable terminal disclaimer language. Additionally, copies of forms PTO/SB/25 and PTO/SB/26 (provided at the end of this Chapter) may be attached to the Office action to provide sample terminal disclaimers.

Pursuant to the last sentence of 35 U.S.C. 253, "any patentee or applicant may disclaim or dedicate to the public... any terminal part of the term, of the patent granted or to be granted". Accordingly, the disclaimer must be of a terminal portion of the term of the entire patent to be granted. A disclaimer of a terminal portion of the term of an individual claim, or individual claims will not be accepted. **>A< disclaimer of the term of individual claims would not be appropriate *>because< the claims of a pending application or proceeding are subject to *>cancellation<, amendment, or renumbering. *>It is further noted that the< statute does not provide for conditional disclaimers >(whether they are terminal disclaimers or statutory disclaimers)< and accordingly, a proposed disclaimer *>that< is made contingent on the allowance of certain claims >or the granting of a petition, is improper and< cannot be accepted. The disclaimer should identify the disclaimant and his or her interest in the application and should specify the date when the disclaimer is to become effective.

B.    Effect of Disclaimers in Continuing Applications and in Reissues

A terminal disclaimer filed to obviate a *>nonstatutory< double patenting rejection is effective only with respect to the application identified in the disclaimer unless by its terms it extends to continuing applications. For example, a terminal disclaimer filed in a parent application normally has no effect on a continuing application claiming filing date benefits of the parent application under 35 U.S.C. 120. A terminal disclaimer filed in a parent application to obviate a >nonstatutory< double patenting rejection does, however, carry over to a continued prosecution application (CPA) filed under 37 CFR 1.53(d) (effective July 14, 2003, CPAs are only available in design applications). The terminal disclaimer filed in the parent application carries over because the CPA retains the same application number as the parent application, i.e., the application number to which the previously filed terminal disclaimer is directed. If applicant does not want the terminal disclaimer to carry over to the CPA, applicant must file a petition under 37 CFR 1.182, along with the required petition fee, requesting the terminal disclaimer filed in the parent application not be carried over to the CPA; see below "Withdrawing a Terminal Disclaimer" (paragraph "A. Before Issuance of Patent"). If applicant files a Request for Continued Examination (RCE) of an application under 37 CFR 1.114 (which can be filed on or after May 29, 2000 for an application filed on or after June 8, 1995), any terminal disclaimer present will continue to operate, *>because< a new application has not been filed, but rather prosecution has been continued in the existing application. A petition under 37 CFR 1.182, along with the required petition fee, may be filed, if withdrawal of the terminal disclaimer is to be requested.

Reissue applications: Where a terminal disclaimer was filed in an original application, a copy of that terminal disclaimer is not required be filed by applicant in the reissue.

**

For IFW reissue applications:

The "Final SPRE Review" form will be filled in to indicate that a terminal disclaimer has been filed for the patent (and will be effective for the patent as it will be reissued). Further, a copy of the terminal disclaimer should be scanned into the reissue application file history by the Technology Center.

C.    Disclaimer Identifies the Wrong Target Application or Patent

In some instances a terminal disclaimer filed to obviate **>a nonstatutory< double patenting rejection will identify the wrong target application or patent (i.e., an application or patent which is not the basis for the double patenting rejection). In these instances, a replacement terminal disclaimer identifying the correct target application or patent would be required by the examiner. Once a correct replacement terminal disclaimer is received, the next Office action should make it clear that "the second terminal disclaimer replaces the first terminal disclaimer, and the first terminal disclaimer is thus void." A second terminal disclaimer fee should not be assessed/charged, *>because< the first fee is applied to the second terminal disclaimer.

D.    Two or More Copending Applications

If two (or more) pending applications are filed, in each of which a rejection of one claimed invention over the other on the ground of provisional **>nonstatutory< double patenting (ODP) is proper, the >provisional< ODP rejection will be made in each application. If the >provisional< ODP rejection is the only rejection remaining in the earlier-filed of the two pending applications, (but the later-filed application is rejectable on other grounds), the examiner should then withdraw *>the provisional ODP< rejection and permit the earlier-filed application to issue as a patent without a terminal disclaimer. If the >provisional< ODP rejection is the only rejection remaining in the later-filed application, (while the earlier-filed application is rejectable on other grounds), a terminal disclaimer must be required in the later-filed application, before the >provisional< ODP rejection can be withdrawn.

If the >provisional< ODP rejections in both applications are the only rejections remaining in those applications, the examiner should then withdraw the >provisional< ODP rejection in the earlier-filed application thereby permitting that application to issue without need of a terminal disclaimer. A terminal disclaimer must be required in the later-filed application before the >provisional< ODP rejection can be withdrawn and the application be permitted to issue.

>The phrase "earlier-filed" is to be interpreted as follows:

(A) Where there is no benefit claim in the two applications, the "earlier-filed" application is the one having the earlier actual filing date;

(B) Where at least one of the two applications is entitled to the benefit of a U.S. nonprovisional application under 35 U.S.C. 120, 121, or 365(c), the "earlier-filed" application is the one having the earlier effective U.S. filing date, when taking into account each of the benefit claims under 35 U.S.C. 120, 121, and 365(c). Entitlement to the benefit claims under 35 U.S.C. 120, 121 and 365(c) assumes appropriate support in the relied-upon earlier-filed application's disclosure (and any intermediate application(s)) for the conflicting claims of the two (or more) applications;

(C) A 35 U.S.C. 119(e) benefit is NOT taken into account in determining which is the "earlier-filed" application;

(D) A foreign priority claim under 35 U.S.C. 119(a) is NOT taken into account in determining which is the "earlier-filed" application.<

If both applications are filed on the same day, **>the provisional ODP rejection made in each of the applications should be maintained until applicant overcomes the rejections by either filing a reply showing that the claims subject to the provisional ODP rejections are patentably distinct or filing a terminal disclaimer in each of the pending applications.<

Where there are three applications containing claims that conflict such that *>a provisional< ODP rejection is made in each application based upon the other two, it is not sufficient to file a terminal disclaimer in only one of the applications addressing the other two applications. Rather, an appropriate terminal disclaimer must be filed in at least two of the applications to link all three together. This is because a terminal disclaimer filed to obviate a *>nonstatutory< double patenting rejection is effective only with respect to the application in which the terminal disclaimer is filed; it is not effective to link the other two applications to each other.

¶ 14.27.03 Fails To Disclaim Terminal Portion of Subject Patent

It fails to disclaim the terminal portion of the subject patent.

Examiner Note:

1. This form paragraph MUST be preceded by form paragraph 14.24 or 14.25 AND 14.26.

2. Use this form paragraph in a reissue application or reexamination proceeding when the period disclaimed is not the correct period or when no period is specified at all.

¶ 14.27.04 Examples of Acceptable Terminal Disclaimer Language in Patent To Be Granted

Examples of acceptable language for making the disclaimer of the terminal portion of any patent granted on the subject application follow:

I. If a Provisional Obviousness-Type Double Patenting Rejection Over A Pending Application was made, use:

The owner, _________________________________, of ____________ percent interest in the instant application hereby disclaims the terminal part of the statutory term of any patent granted on the instant application which would extend beyond the expiration date of the full statutory term of any patent granted on pending reference Application Number ________________, filed on _____________, as such term is defined in 35 U.S.C. 154 and 173, and as the term of any patent granted on said reference application may be shortened by any terminal disclaimer filed prior to the grant of any patent on the pending reference application. The owner hereby agrees that any patent so granted on the instant application shall be enforceable only for and during such period that it and any patent granted on the reference application are commonly owned. This agreement runs with any patent granted on the instant application and is binding upon the grantee, its successors or assigns.

II. If an Obviousness-Type Double Patenting Rejection Over A Prior Patent was made, use:

The owner, _________________________________, of ____________ percent interest in the instant application hereby disclaims the terminal part of the statutory term of any patent granted on the instant application which would extend beyond the expiration date of the full statutory term of reference patent No. ________________ as the term of said prior patent is defined in 35 U.S.C. 154 and 173 , and as the term of said reference patent is presently shortened by any terminal disclaimer. The owner hereby agrees that any patent so granted on the instant application shall be enforceable only for and during such period that it and the reference patent are commonly owned. This agreement runs with any patent granted on the instant application and is binding upon the grantee, its successors or assigns.

Alternatively, Form PTO/SB/25 may be used for situation I, and Form PTO/SB/26 may be used for situation II; a copy of each form may be found at the end of MPEP § 1490.

Examiner Note:

1. To provide examples of acceptable terminal disclaimer language in a patent (e.g., for a reexamination situation), other than for a terminal disclaimer based on activities undertaken within the scope of a joint research agreement, use form paragraph 14.27.06.

2. To provide examples of acceptable terminal disclaimer language for a terminal disclaimer based on activities undertaken within the scope of a joint research agreement, (a) use form paragraph 14.27.07 for making the disclaimer of the terminal portion of a patent to be granted on an application (generally, an application being examined), and (b) use form paragraph 14.27.08 for making the disclaimer of the terminal portion of an existing patent (e.g., for a reexamination situation).

¶ 14.27.06 Examples of Acceptable Terminal Disclaimer Language in Patent (Reexamination Situation)

Examples of acceptable language for making the disclaimer of the terminal portion of the patent being reexamined (or otherwise for an existing patent) follow:

I. If a Provisional Obviousness-Type Double Patenting Rejection Over A Pending Application was made, or is otherwise believed to be applicable to the patent, use:

The patent owner hereby disclaims the terminal part of the instant patent, which would extend beyond the expiration date of the full statutory term of any patent granted on pending Application Number ______________, filed on ______________, as such term is defined in 35 U.S.C. 154 and 173, and as the term of any patent granted on said application may be shortened by any terminal disclaimer filed prior to the grant of any patent on the pending application.

Examiner Note:

1. To provide examples of acceptable terminal disclaimer language in a patent to be granted on an application (generally, an application being examined) for a terminal disclaimer based on activities undertaken within the scope of a joint research agreement, use form paragraph 14.27.07.

2. To provide examples of acceptable terminal disclaimer language for a terminal disclaimer in a situation other than one based on activities undertaken within the scope of a joint research agreement, (a) use form paragraph 14.27.04 for making the disclaimer of the terminal portion of a patent to be granted on an application (generally, an application being examined), and (b) use form paragraph 14.27.06 for making the disclaimer of the terminal portion of an existing patent (e.g., for a reexamination situation).

¶ 14.28 Failure To State Capacity To Sign

The person who signed the terminal disclaimer has failed to state his/her capacity to sign for the corporation, or other business entity or organization, and he/she has not been established as being authorized to act on behalf of the assignee.

Examiner Note:

1. This form paragraph MUST be preceded by form paragraph 14.24 or 14.25 AND 14.26.

¶ 14.29 Not Recognized as Officer of Assignee - "Sub-Heading" Only

The person who signed the terminal disclaimer is not recognized as an officer of the assignee, and he/she has not been established as being authorized to act on behalf of the assignee. See MPEP § 324.

Examiner Note:

1. This form paragraph is to be used when the person signing the terminal disclaimer is not an authorized officer as defined in MPEP § 324.

2. This form paragraph MUST be preceded by form paragraphs 14.24 or 14.25 and followed by form paragraphs 14.29.01 and/or 14.29.02 when appropriate. An attorney or agent of record is always authorized to sign the terminal disclaimer, even though there is no indication that he or she is an officer of the assignee.

3. Use form paragraph 14.29.02 to explain how an official, other than a recognized officer, may properly sign a terminal disclaimer.

¶ 14.29.01 Attorney/Agent Not of Record

An attorney or agent, not of record, is not authorized to sign a terminal disclaimer in the capacity as an attorney or agent acting in a representative capacity as provided by 37 CFR 1.34 (a). See 37 CFR 1.321(b) and/or (c).

Examiner Note:

1. This form paragraph MUST be preceded by form paragraphs 14.24 or 14.25 AND 14.29.

2. An attorney or agent, however, may sign a terminal disclaimer provided he/she is an attorney or agent of record or is established as an appropriate official of the assignee. To suggest to the attorney or agent, not of record, how he/she may establish status as an appropriate official of the assignee to sign a terminal disclaimer, use form paragraph 14.29.02.

¶ 14.29.02 Criteria To Accept Terminal Disclaimer When Signed by a Non-Recognized Officer

It would be acceptable for a person, other than a recognized officer, to sign a terminal disclaimer, provided the record for the application includes a statement that the person is empowered to sign terminal disclaimers and/or act on behalf of the assignee.

Accordingly, a new terminal disclaimer which includes the above empowerment statement will be considered to be signed by an appropriate official of the assignee. A separately filed paper referencing the previously filed terminal disclaimer and containing a proper empowerment statement would also be acceptable.

Examiner Note:

1. This form paragraph MUST be preceded by form paragraphs 14.24 or 14.25 AND 14.29.

2. When form paragraph 14.29 is used to indicate that a terminal disclaimer is denied because it was not signed by a recognized officer nor by an attorney or agent of record, this form paragraph should be used to point out one way to correct the problem.

3. While an indication of the person's title is desirable, its inclusion is not mandatory when this option is employed.

4. A sample terminal disclaimer should be sent with the Office action.

¶ 14.30 No Evidence of Chain of Title to Assignee - Application

The assignee has not established its ownership interest in the application, in order to support the terminal disclaimer. There is no submission in the record establishing the ownership interest by either (a) providing documentary evidence of a chain of title from the original inventor(s) to the assignee and a statement affirming that the documentary evidence of the chain of title form the original owner to the assignee was, or concurrently is being, submitted for recordation pursuant to 37 CFR 3.11, or (b) specifying (by reel and frame number) where such documentary evidence is recorded in the Office ( 37 CFR 3.73(b)).

Examiner Note:

1. This form paragraph MUST be preceded by form paragraph 14.24 or 14.25.

2. Where an attorney or agent of record signs a terminal disclaimer, there is no need to provide a statement under 37 CFR 3.73(b). Thus, this form paragraph should not be used.

3. It should be noted that the documentary evidence or the specifying of reel and frame number may be found in the terminal disclaimer itself or in a separate paper.

¶ 14.30.01 No Evidence of Chain of Title to Assignee - Patent

The assignee has not established its ownership interest in the patent, in order to support the terminal disclaimer. There is no submission in the record establishing the ownership interest by either (a) providing documentary evidence of a chain of title from the original inventor(s) to the assignee and a statement affirming that the documentary evidence of the chain of title form the original owner to the assignee was, or concurrently is being, submitted for recordation pursuant to 37 CFR 3.11, or (b) specifying (by reel and frame number) where such documentary evidence is recorded in the Office ( 37 CFR 3.73(b)).

Examiner Note:

1. This form paragraph MUST be preceded by form paragraph 14.24 or 14.25.

2. Where an attorney or agent of record signs a terminal disclaimer, there is no need to provide a statement under 37 CFR 3.73(b). Thus, this form paragraph should not be used.

3. It should be noted that the documentary evidence or the specifying of reel and frame number may be found in the terminal disclaimer itself or in a separate paper in the application.

¶ 14.30.02 Evidence of Chain of Title to Assignee - Submission Not Signed by Appropriate Party - Terminal Disclaimer Is Thus Not Entered

The submission establishing the ownership interest of the assignee is informal. There is no indication of record that the party who signed the submission establishing the ownership interest is authorized to sign the submission ( 37 CFR 3.73(b)).

Examiner Note:

1. This form paragraph MUST be preceded by form paragraph 14.24 or 14.25.

2. Where an attorney or agent of record signs a terminal disclaimer, there is no need to provide any statement under 37 CFR 3.73(b). Thus, this form paragraph should not be used.

3. This form paragraph should be followed by one of form paragraphs 14.16.02 or 14.16.03. In rare situations where BOTH form paragraphs 14.16.02 and 14.16.03 do not apply and thus cannot be used, the examiner should instead follow this form paragraph with a detailed statement of why the there is no authorization to sign.

4. Use form paragraph 14.16.06 to point out one way to correct the problem.

¶ 14.32 Application/Patent Which Forms Basis for Rejection Not Identified

The application/patent which forms the basis for the double patenting rejection is not identified in the terminal disclaimer.

Examiner Note:

1. This form paragraph MUST be preceded by form paragraph 14.24 or 14.25.

2. Use this form paragraph when no information is presented. If incorrect information is contained in the terminal disclaimer, use form paragraphs 14.26 and 14.26.05.

¶ 14.33 37 CFR 3.73 - Establishing Right of Assignee To Take Action

The following is a statement of 37 CFR 3.73:

37 CFR 3.73 Establishing right of assignee to take action.

(a) The inventor is presumed to be the owner of a patent application, and any patent that may issue therefrom, unless there is an assignment. The original applicant is presumed to be the owner of a trademark application or registration, unless there is an assignment.

(b)(1) In order to request or take action in a patent or trademark matter, the assignee must establish its ownership of the patent or trademark property of paragraph (a) of this section to the satisfaction of the Director. The establishment of ownership by the assignee may be combined with the paper that requests or takes the action. Ownership is established by submitting to the Office a signed statement identifying the assignee, accompanied by either:

(i) Documentary evidence of a chain of title from the original owner to the assignee (e.g., copy of an executed assignment). For trademark matters only, the documents submitted to establish ownership may be required to be recorded pursuant to § 3.11 in the assignment records of the Office as a condition to permitting the assignee to take action in a matter pending before the Office. For patent matters only, the submission of the documentary evidence must be accompanied by a statement affirming that the documentary evidence of the chain of title from the original owner to the assignee was, or concurrently is being, submitted for recordation pursuant to § 3.11; or

(ii) A statement specifying where documentary evidence of a chain of title from the original owner to the assignee is recorded in the assignment records of the Office (e.g., reel and frame number).

(2) The submission establishing ownership must show that the person signing the submission is a person authorized to act on behalf of the assignee by:

(i) Including a statement that the person signing the submission is authorized to act on behalf of the assignee; or

(ii) Being signed by a person having apparent authority to sign on behalf of the assignee, e.g., an officer of the assignee.

(c) For patent matters only:

(1) Establishment of ownership by the assignee must be submitted prior to, or at the same time as, the paper requesting or taking action is submitted.

(2) If the submission under this section is by an assignee of less than the entire right, title and interest, such assignee must indicate the extent (by percentage) of its ownership interest, or the Office may refuse to accept the submission as an establishment of ownership.

¶ 14.34 Requirement for Statement To Record Assignment Submitted With Terminal Disclaimer

The assignment document filed on [1] is not acceptable as the documentary evidence required by 37 CFR 3.73. The submission of the documentary evidence was not accompanied by a statement affirming that the documentary evidence of the chain of title from the original owner to the assignee was, or concurrently is being, submitted for recordation pursuant to 37 CFR 3.11. See 37 CFR 3.11 and MPEP § 302.

Examiner Note:

1. In bracket 1, insert the date the assignment document was filed.

2. This form paragraph should be used when an assignment document (an original, facsimile, or copy) is submitted to satisfy 37 CFR 3.73(b) was not accompanied by a statement affirming that the documentary evidence of the chain of title from the original owner to the assignee was, or concurrently is being, submitted for recordation, and the documentary evidence has not been recorded among the assignment records of the Office.

¶ 14.35 Disclaimer Fee Not Required Twice - Applicant

It should be noted that applicant is not required to pay another disclaimer fee as set forth in 37 CFR 1.20(d) when submitting a replacement or supplemental terminal disclaimer.

Examiner Note:

1. This form paragraph can be used to notify an applicant that another disclaimer fee will not be required when a replacement or supplemental terminal disclaimer is submitted.

2. Use form paragraph 14.35.01 for providing notification to patent owner, rather than an applicant.

¶ 14.35.01 Disclaimer Fee Not Required Twice - Patent Owner

It should be noted that patent owner is not required to pay another disclaimer fee as set forth in 37 CFR 1.20(d) when submitting a replacement or supplemental terminal disclaimer.

Examiner Note:

This form paragraph can be used to notify a patent owner that another disclaimer fee will not be required when a replacement or supplemental terminal disclaimer is submitted.

¶ 14.36 Suggestion That "Applicant" Request a Refund

Since the required fee for the terminal disclaimer was previously paid, applicant's payment of an additional terminal disclaimer fee is not required. Applicant may request a refund of this additional terminal disclaimer fee by submitting a written request for a refund and a copy of this Office action to: Mail Stop 16, Director of the United States Patent and Trademark Office, P.O. Box 1450, Alexandria, Virginia 22313-1450.

Examiner Note:

1. This form paragraph should be used to notify applicant that a refund can be obtained if another terminal disclaimer fee was paid when a replacement or supplemental terminal disclaimer was submitted.

2. Note - If applicant has authorized or requested a fee refund to be credited to a specific Deposit Account or credit card, then an appropriate credit should be made to that Deposit Account or credit card and this paragraph should NOT be used.

3. Use form paragraph 14.36.01 for providing notification to patent owner, rather than an applicant.

¶ 14.36.01 Suggestion That "Patent Owner" Request a Refund

Since the required fee for the terminal disclaimer was previously paid, patent owner's payment of an additional terminal disclaimer fee is not required. Patent owner may request a refund of this additional terminal disclaimer fee by submitting a written request for a refund and a copy of this Office action to: Mail Stop 16, Director of the United States Patent and Trademark Office, P.O. Box 1450, Alexandria, Virginia 22313-1450.

¶ 14.37 Samples of a Terminal Disclaimer Over a Pending Application and Assignee Statement Enclosed

Enclosed with this Office action is a sample terminal disclaimer which is effective to overcome a provisional obviousness-type double patenting rejection over a pending application ( 37 CFR 1.321(b) and (c)).

Also enclosed is a sample Statement Under 37 CFR 3.73(b) (Form PTO/SB/96) which an assignee may use in order to ensure compliance with the rule. Part A of the Statement is used when there is a single assignment from the inventor(s). Part B of the Statement is used when there is a chain of title. The "Copies of assignments..." box should be checked when the assignment document(s) (set forth in part A or part B) is/are not recorded in the Office, and a copy of the assignment document(s) is/are attached. When the "Copies of assignments..." box is checked, either the part A box or the part B box, as appropriate, must be checked, and the "Reel_____, Frame_____" entries should be left blank. If the part B box is checked, and copies of assignments are not included, the "From:______ To:______" blank(s) must be filled in. This statement should be used the first time an assignee seeks to take action in an application under 37 CFR 3.73(b), e.g., when signing a terminal disclaimer or a power of attorney.

Examiner Note:

1. This form paragraph can be used to provide applicant samples of a terminal disclaimer which contains the necessary clauses to overcome a provisional obviousness-type double patenting rejection over a pending application and a Statement to be signed by an assignee to ensure compliance with 37 CFR 3.73(b).

2. Note that the requirements for compliance with 37 CFR 3.73 (b) have been made more liberal, such that certain specifics of the sample statement are no longer required. At present, in order to comply with 37 CFR 3.73(b), the assignee's ownership interest must be established by (a) filing in the application or patent evidence of a chain of title from the original owner to the assignee and a statement affirming that the documentary evidence of the chain of title from the original owner to the assignee was, or concurrently is being, submitted for recordation pursuant to 37 CFR 3.11, or (b) specifying in the record of the application or patent where such evidence is recorded in the Office (e.g., reel and frame number, etc.). The submission with respect to (a) and (b) to establish ownership must be signed by a party authorized to act on behalf of the assignee.

(See your Technology Center Paralegal or Special Program Examiner for copies of the sample terminal disclaimer and Statement Under 37 CFR 3.73(b) to enclose with the Office action. Alternatively, it is permissible to copy the sample terminal disclaimer found after MPEP § 1490 and the Sample Statement Under 37 CFR 3.73(b) found after MPEP § 324.)

At present, in order to comply with 37 CFR 3.73(b), the assignee's ownership interest must be established by (a) filing in the application or patent evidence of a chain of title from the original owner to the assignee and a statement affirming that the documentary evidence of the chain of title from the original owner to the assignee was, or concurrently is being, submitted for recordation pursuant to 37 CFR 3.11, or (b) specifying in the record of the application or patent where such evidence is recorded in the Office (e.g., reel and frame number, etc.). The submission with respect to (a) and (b) to establish ownership must be signed by a party authorized to act on behalf of the assignee.

(See your Technology Center Paralegal or Special Program Examiner for a copy of the sample Statement Under 37 CFR 3.73(b) to enclose with the Office action. Alternatively, it is permissible to copy the sample Statement Under 37 CFR 3.73(b) found after MPEP § 324.)

VII.    WITHDRAWING A RECORDED TER-MINAL DISCLAIMER

If timely requested, a recorded terminal disclaimer may be withdrawn before the application in which it is filed issues as a patent, or in a reexamination proceeding, before the reexamination certificate issues. After a patent or reexamination certificate issues, it is unlikely that a recorded terminal disclaimer will be nullified.

A. Before Issuance Of Patent

While the filing and recordation of an unnecessary terminal disclaimer has been characterized as an "un­happy circumstance" in In re Jentoft, 392 F.2d 633, 157 USPQ 363 (CCPA 1968), there is no statutory prohibition against nullifying or otherwise canceling the effect of a recorded terminal disclaimer which was erroneously filed before the patent issues. *>Because< the terminal disclaimer would not take effect until the patent is granted, and the public has not had the opportunity to rely on the terminal disclaimer, relief from this unhappy circumstance may be available by way of petition or by refiling the application (other than by refiling it as a CPA).

Under appropriate circumstances, consistent with the orderly administration of the examination process, the nullification of a recorded terminal disclaimer may be addressed by filing a petition under 37 CFR 1.182 requesting withdrawal of the recorded terminal disclaimer. Petitions seeking to reopen the question of the propriety of the double patenting rejection that prompted the filing of the terminal disclaimer have not been favorably considered. The filing of a continuing application other than a CPA, while abandoning the application in which the terminal disclaimer has been filed, will typically nullify the effect of a terminal disclaimer. The filing of a Request for Continued Examination (RCE) of an application under 37 CFR 1.114 will not nullify the effect of a terminal disclaimer, *>because< a new application has not been filed, but rather prosecution has been continued in the existing application.

B. After Issuance Of Patent

The mechanisms to correct a patent - Certificate of Correction ( 35 U.S.C. 255), reissue ( 35 U.S.C. 251), and reexamination ( 35 U.S.C. 305) - are not available to withdraw or otherwise nullify the effect of a recorded terminal disclaimer. As a general principle, public policy does not favor the restoration to the patent owner of something that has been freely dedicated to the public, particularly where the public interest is not protected in some manner - e.g., intervening rights in the case of a reissue patent. See, e.g., Altoona Publix Theatres v. American Tri-Ergon Corp., 294 U.S. 477, 24 USPQ 308 (1935).

Certificates of Correction ( 35 U.S.C. 255) are available for the correction of an applicant's mistake. The scope of this remedial provision is limited in two ways - by the nature of the mistake for which correction is sought and the nature of the proposed correction. In re Arnott, 19 USPQ2d 1049 (Comm'r Pat. 1991). The nature of the mistake for which correction is sought is limited to those mistakes that are:

(A) of a clerical nature;

(B) of a typographical nature; or

(C) of a minor character.

The nature of the proposed correction is limited to those situations where the correction does not involve changes which would:

(A) constitute new matter, or

(B) require reexamination.

A mistake in filing a terminal disclaimer does not fall within any of the categories of mistake for which a certificate of correction of applicant's mistake is permissible, and any attempt to remove or nullify the effect of the terminal disclaimer would typically require reexamination of the circumstances under which it was filed.

Although the remedial nature of reissue ( 35 U.S.C. 251) is well recognized, reissue is not available to correct all errors. It has been the Office position that reissue is not available to withdraw or otherwise nullify the effect of a terminal disclaimer recorded in an issued patent. First, the reissue statute only authorizes the Director of the USPTO to reissue a patent "for the unexpired part of the term of the original patent." *>Because< the granting of a reissue patent without the effect of a recorded terminal disclaimer would result in extending the term of the original patent, reissue under these circumstances would be contrary to the statute. Second, the principle against recapturing something that has been intentionally dedicated to the public dates back to Leggett v. Avery, 101 U.S. 256 (1879). The attempt to restore that portion of the patent term that was dedicated to the public to secure the grant of the original patent would be contrary to this recapture principle. Finally, applicants have the opportunity to challenge the need for a terminal disclaimer during the prosecution of the application that issues as a patent. "Reissue is not a substitute for Patent Office appeal procedures." Ball Corp. v. United States, 729 F.2d 1429, 1435, 221 USPQ 289, 293 (Fed. Cir. 1984). Where applicants did not challenge the propriety of the examiner's **>nonstatutory< double patenting rejection, but filed a terminal disclaimer to avoid the rejection, the filing of the terminal disclaimer did not constitute error within the meaning of 35 U.S.C. 251. Ex parte Anthony, 230 USPQ 467 (Bd. App. 1982), aff'd, No. 84-1357 (Fed. Cir. June 14, 1985).

Finally, the nullification of a recorded terminal disclaimer would not be appropriate in a reexamination proceeding. There is a prohibition ( 35 U.S.C. 305) against enlarging the scope of a claim during a reexamination proceeding. As noted by the Board in Anthony, supra, if a terminal disclaimer was nullified, "claims would be able to be sued upon for a longer period than would the claims of the original patent. Therefore, the vertical scope, as opposed to the horizontal scope (where the subject matter is enlarged), would be enlarged."

>Where a terminal disclaimer was submitted to overcome a nonstatutory double patenting rejection (made during prosecution of an application which has now issued as a patent), and the numbers for the patent being disclaimed in the terminal disclaimer were inadvertently transposed (e.g., 6,444,316 written as 6,444,136), a petition under 37 CFR 1.182 may be filed to withdraw the terminal disclaimer with the incorrect (transposed) patent number (recorded in the issued patent), and replace it with a corrected terminal disclaimer having the correct patent number. In this instance, the inadvertency is clear from the record. If the transposing error resulted in an earlier patent term expiration date than provided by the corrected terminal disclaimer, a statement must be included in the corrected terminal disclaimer to retain that earlier expiration date. The absence of such a statement will result in the Office declining to exercise its discretion to grant relief.<
