2304.02   Applicant Suggestion [R-4]

37 C.F.R. 41.202   Suggesting an interference.

  • (a) Applicant. An applicant, including a reissue applicant, may suggest an interference with another application or a patent. The suggestion must:
    • (1) Provide sufficient information to identify the application or patent with which the applicant seeks an interference,
    • (2) Identify all claims the applicant believes interfere, propose one or more counts, and show how the claims correspond to one or more counts,
    • (3) For each count, provide a claim chart comparing at least one claim of each party corresponding to the count and show why the claims interfere within the meaning of § 41.203 (a),
    • (4) Explain in detail why the applicant will prevail on priority,
    • (5) If a claim has been added or amended to provoke an interference, provide a claim chart showing the written description for each claim in the applicant’s specification, and
    • (6) For each constructive reduction to practice for which the applicant wishes to be accorded benefit, provide a chart showing where the disclosure provides a constructive reduction to practice within the scope of the interfering subject matter.

*****

  • (d) Requirement to show priority under 35 U.S.C. 102(g). (1) When an applicant has an earliest constructive reduction to practice that is later than the apparent earliest constructive reduction to practice for a patent or published application claiming interfering subject matter, the applicant must show why it would prevail on priority.
    • (2) If an applicant fails to show priority under paragraph (d)(1) of this section, an administrative patent judge may nevertheless declare an interference to place the applicant under an order to show cause why judgment should not be entered against the applicant on priority. New evidence in support of priority will not be admitted except on a showing of good cause. The Board may authorize the filing of motions to redefine the interfering subject matter or to change the benefit accorded to the parties.

*****

When an applicant suggests an interference under 37 CFR 41.202 (a), an examiner must review the suggestion for formal sufficiency. As explained in MPEP § 2304.02(c), the examiner is generally not responsible for determining the substantive adequacy of any priority showing. The examiner may, however, offer pertinent observations on any showing when the suggested interference is referred to the Board of Patent Appeals and Interferences. The observations may be included as an attachment to the Form PTO-850.

Form paragraphs 23.06 to 23.06.06 may be used to acknowledge applicant’s suggestion for interference under 37 CFR 41.202 (a) that failed to comply with one or more of paragraphs (a)(1) to (a)(6) of 37 CFR 41.202.

¶ 23.06    Applicant Suggesting an Interference

Applicant has suggested an interference pursuant to 37 CFR 41.202(a)  in a communication filed [1].

Examiner Note:

1. Use this form paragraph if applicant has suggested an interference under 37 CFR 41.202(a)  and applicant has failed to comply with one or more of paragraphs (a)(1) to (a)(6) of 37 CFR 41.202.

2. In bracket 1, insert the date of applicant’s communication.

3. This form paragraph must be followed by one or more of form paragraphs 23.06.01 to 23.06.03 and end with form paragraph 23.06.04.

¶ 23.06.01    Failure to Identify the Other Application or Patent

Applicant failed to provide sufficient information to identify the application or patent with which the applicant seeks an interference. See 37 CFR 41.202(a)(1)  and MPEP § 2304.02(a).

¶ 23.06.02    Failure to Identify the Counts and Corresponding Claims

Applicant failed to (1) identify all claims the applicant believes interfere, and/or (2) propose one or more counts, and/or (3) show how the claims correspond to one or more counts. See 37 CFR 41.202(a)(2)  and MPEP § 2304.02(b).

¶ 23.06.03    Failure to Provide Claim Chart Comparing At Least One Claim

Applicant failed to provide a claim chart comparing at least one claim of each party corresponding to the count. See 37 CFR 41.202(a)(3)  and MPEP § 2304.02(c).

¶ 23.06.04    Failure to Explain in Detail Why Applicant Will Prevail on Priority

Applicant failed to provide a detailed explanation as to why applicant will prevail on priority. See 37 CFR 41.202(a)(4),  (a)(6), (d) and MPEP § 2304.02(c).

¶ 23.06.05    Claim Added/Amended; Failure to Provide Claim Chart Showing Written Description

Claim [1] has been added or amended in a communication filed on [2] to provoke an interference. Applicant failed to provide a claim chart showing the written description for each claim in the applicant’s specification. See 37 CFR 41.202(a)(5)  and MPEP § 2304.02(d).

¶ 23.06.06    Time Period for Reply

Applicant is given ONE MONTH or THIRTY DAYS, whichever is longer, from the mailing date of this communication to correct the deficiency(ies). THE PROVISIONS OF 37 CFR 1.136  DO NOT APPLY TO THE TIME SPECIFIED IN THIS ACTION.

2304.02(a)   Identifying the Other Application or Patent [R-4]

37 C.F.R. 41.202   Suggesting an interference.

  • (a) Applicant. An applicant, including a reissue applicant, may suggest an interference with another application or a patent. The suggestion must:
    • (1) Provide sufficient information to identify the application or patent with which the applicant seeks an interference,

*****

Usually an applicant seeking an interference will know the application serial number or the patent number of the application or patent, respectively, with which it seeks an interference. If so, providing that number will fully meet the identification requirement of 37 CFR 41.202 (a)(1).

Occasionally, an applicant will believe another interfering application exists based only on indirect evidence, for instance through a journal article, a "patent pending" notice, or a foreign published application. In such cases, information about likely named inventors and likely assignees may lead to the right application. The applicant should be motivated to help the examiner identify the application since inadequate information may prevent the declaration of the suggested interference.

2304.02(b)   Counts and Corresponding Claims [R-4]

37 C.F.R. 41.202   Suggesting an interference.

  • (a) Applicant. An applicant, including a reissue applicant, may suggest an interference with another application or a patent. The suggestion must:

*****

  • (2) Identify all claims the applicant believes interfere, propose one or more counts, and show how the claims correspond to one or more counts,
  • (3) For each count, provide a claim chart comparing at least one claim of each party corresponding to the count and show why the claims interfere within the meaning of § 41.203 (a),

*****

The applicant must identify at least one patentable claim from every application or patent that interferes for each count. A count is just a description of the interfering subject matter, which the Board of Patent Appeals and Interferences uses to determine what evidence may be used to prove priority under 35 U.S.C. 102 (g)(1).

The examiner must confirm that the applicant has (A) identified at least one patentable count, (B) identified at least one patentable claim from each party for each count, and (C) has provided a claim chart comparing at least one set of claims for each count. The examiner need not agree with the applicant’s suggestion. The examiner’s role is to confirm that there are otherwise patentable interfering claims and that the formalities of 37 CFR 41.202  are met.

2304.02(c)   Explaining Priority [R-4]

37 C.F.R. 41.202   Suggesting an interference.

  • (a) Applicant. An applicant, including a reissue applicant, may suggest an interference with another application or a patent. The suggestion must:

*****

  • (4) Explain in detail why the applicant will prevail on priority,

*****

  • (6) For each constructive reduction to practice for which the applicant wishes to be accorded benefit, provide a chart showing where the disclosure provides a constructive reduction to practice within the scope of the interfering subject matter.

*****

  • (d) Requirement to show priority under 35 U.S.C. 102(g). (1) When an applicant has an earliest constructive reduction to practice that is later than the apparent earliest constructive reduction to practice for a patent or published application claiming interfering subject matter, the applicant must show why it would prevail on priority.
    • (2) If an applicant fails to show priority under paragraph (d)(1) of this section, an administrative patent judge may nevertheless declare an interference to place the applicant under an order to show cause why judgment should not be entered against the applicant on priority. New evidence in support of priority will not be admitted except on a showing of good cause. The Board may authorize the filing of motions to redefine the interfering subject matter or to change the benefit accorded to the parties.

*****

A description in an application that would have anticipated the subject matter of a count is called a constructive reduction-to-practice of the count. One disclosed embodiment is enough to have anticipated the subject matter of the count. If the application is relying on a chain of benefit disclosures under any of 35 U.S.C. 119, 120, 121  and 365, then the anticipating disclosure must be continuously disclosed through the entire benefit chain or no benefit may be accorded.

If the application has an earlier constructive reduction-to-practice than the apparent earliest constructive reduction-to-practice of the other application or patent, then the applicant may simply explain its entitlement to its earlier constructive reduction-to-practice. Otherwise, the applicant must (A) antedate the earliest constructive reduction-to-practice of the other application or patent, (B) demonstrate why the other application or patent is not entitled to its apparent earliest constructive reduction-to-practice, or (C) provide some other reason why the applicant should be considered the prior inventor.

The showing of priority may look similar to showings under 37 CFR 1.130 -1.132, although there are differences particularly in the scope of what must be shown. In any case, with the exception discussed below, the examiner is not responsible for examining the substantive sufficiency of the showing.

I.   REJECTION UNDER 35 U.S.C. 102 (a) or 102 (e)

If an application claim is subject to a rejection under 35 U.S.C. 102 (a) or 102 (e) and the applicant files a suggestion under 37 CFR 41.202 (a) rather than a declaration under 37 CFR 1.130 -1.132, then the examiner must review the suggestion to verify that the applicant’s showing, taken at face value, is sufficient to overcome the rejection. If the examiner determines that the showing is not sufficient, then the examination is not completed, 37 CFR 41.102, the rejection should be maintained and the suggestion should not be referred to the Board of Patent Appeals and Interferences (Board) for an interference.

II.   COMPLIANCE WITH 35 U.S.C. 135 (b)

If an application claim interferes with a claim of a patent or published application, and the claim was added to the application by an amendment filed more than one year after issuance of the patent, or the application was not filed until more than one year after issuance of the patent (but the patent is not a statutory bar), then under the provisions of 35 U.S.C. 135 (b), an interference will not be declared unless at least one of the claims which were in the application, or in a parent application, prior to expiration of the one-year period was for "substantially the same subject matter" as at least one of the claims of the patent.

If the applicant does not appear to have had a claim for "substantially the same subject matter" as at least one of the patent claims prior to the expiration of the one-year period, the examiner may require, 35 U.S.C. 132, that the applicant explain how the requirements of 35 U.S.C. 135 (b) are met. Further, if the patent issued from an application which was published under 35 U.S.C. 122 (b), note the one year from publication date limitation found in 35 U.S.C. 135 (b)(2) with respect to applications filed after the date of publication.

The obviousness test is not the standard for determining whether the subject matter is the same or substantially the same. Rather the determination turns on the presence or absence of a different material limitation in the claim. These tests are distinctly different. The analysis focuses on the interfering claim to determine whether all material limitations of the interfering claim necessarily occur in a prior claim. In re Berger, 279 F.3d 975, 61 USPQ2d 1523 (Fed. Cir. 2002). If none of the claims which were present in the application, or in a parent application, prior to expiration of the one-year period meets the "substantially the same subject matter" test, the interfering claim should be rejected under 35 U.S.C. 135 (b). In re McGrew, 120 F.3d 1236, 43 USPQ2d 1632 (Fed. Cir. 1997). Note that the expression "prior to one year from the date on which the patent was granted" in 35 U.S.C. 135 (b) includes the one-year anniversary date of the issuance of a patent. Switzer v. Sockman, 333 F.2d 935, 142 USPQ 226 (CCPA 1964).

Form paragraph 23.14 may be used to reject a claim as not being made prior to one year of the patent issue date. Form paragraph 23.14.01 may be used to reject a claim as not being made prior to one year from the application publication date.

¶ 23.14    Claims Not Copied Within One Year of Patent Issue Date

Claim [l] rejected under 35 U.S.C. 135(b)(1)  as not being made prior to one year from the date on which U.S. Patent No. [2] was granted. See In re McGrew, 120 F.3d 1236, 1238, 43 USPQ2d 1632, 1635 (Fed. Cir. 1997) where the Court held that 35 U.S.C. 135(b)  may be used as a basis for ex parte rejections.

¶ 23.14.01    Claims Not Copied Within One Year Of Application Publication Date

Claim [l] rejected under 35 U.S.C. 135(b)(2)  as not being made prior to one year from the date on which [2] was published under 35 U.S.C. 122(b). See In re McGrew, 120 F.3d 1236, 1238, 43 USPQ2d 1632, 1635 (Fed. Cir. 1997) where the Court held that 35 U.S.C. 135(b)  may be used as a basis for ex parte rejections.

Examiner Note:

1. In bracket 2, insert the publication number of the published application.

2. This form paragraph should only be used if the application being examined was filed after the publication date of the published application.

2304.02(d)   Adequate Written Description [R-4]

37 C.F.R. 41.202   Suggesting an interference.

  • (a) Applicant. An applicant, including a reissue applicant, may suggest an interference with another application or a patent. The suggestion must:

*****

  • (5) If a claim has been added or amended to provoke an interference, provide a claim chart showing the written description for each claim in the applicant’s specification, and

*****

An applicant is not entitled to an interference simply because applicant wants one. The interfering claim must be allowable, particularly with respect to the written description supporting the interfering claim.

Historically, an applicant provoked an interference by copying a claim from its opponent. The problem this practice created was that differences in the underlying disclosures might leave the claim allowable to one party, but not to the other; or despite identical claim language differences in the disclosures might require that the claims be construed differently.

Rather than copy a claim literally, the better practice is to add (or amend to create) a fully supported claim and then explain why, despite any apparent differences, the claims define the same invention. 37 CFR 41.203 (a). The problem of inadequate written description in claims added or amended to provoke an interference is so great that the issue has been singled out for heightened scrutiny early in the course of an interference. 37 CFR 41.201, under "Threshold issue."
