MPEP § 713.04
A complete written statement as to the substance of any interview (including any electronic communication that discussed the merits of an application) must be made of record in the application, whether or not an agreement with the examiner was reached at the interview. The requirement may be satisfied by submitting a transcript generated during an electronic communication exchange. See 37 CFR 1.133(b) and MPEP §§ 502.03 and 713.01.

All business with the Patent and Trademark Office should be transacted in writing. The personal attendance of applicants or their attorneys or agents at the Patent and Trademark Office is unnecessary. The action of the Patent and Trademark Office will be based exclusively on the written record in the Office. No attention will be paid to any alleged oral promise, stipulation, or understanding in relation to which there is disagreement or doubt.
The action of the U.S. Patent and Trademark Office cannot be based exclusively on the written record in the Office if that record is itself incomplete through the failure to record the substance of interviews. Accordingly, examiners must complete an Interview Summary form for each interview where a matter of substance has been discussed during the interview. For an applicant-initiated interview, a complete written statement as to the substance of the interview must be made of record in the application file in the reply to an outstanding action or within the set period if no reply is outstanding. It is the responsibility of the applicant to make the substance of the interview of record in the application file, and it is the examiner’s responsibility to see that such a record is made and to correct material inaccuracies which bear directly on the question of patentability. For an examiner-initiated interview, it is the responsibility of the examiner to make the substance of the interview of record either on an Interview Summary form or, when the interview results in allowance of the application, by incorporating a complete record of the interview in an examiner’s amendment. The examiner should be sure to indicate whether it is necessary for the applicant to submit a substance of the interview.
An examiner may use form PTOL-413/413b to record the substance of an interview. A sample Interview Summary form (PTOL-413/413b) for an applicant-initiated interview is reproduced below.

A sample Interview Summary form (PTOL-413/413b) for an examiner-initiated interview is reproduced below.

See subsection I below for a list of the items to be included for complete and proper recordation of an interview. Discussions regarding only procedural matters, directed solely to restriction requirements for which interview recordation is otherwise provided for in MPEP § 812.01, or pointing out typographical errors in Office actions or the like, are excluded from the interview recordation procedures.
For both applicant-initiated and examiner-initiated interviews, it is recommended the examiner begin completing an Interview Summary form in advance of the interview by identifying the rejections, claims and prior art documents to be discussed. The examiner should complete the "Issues Discussed" portion of the Interview Summary form at the conclusion of the interview. Upon completion of the interview, a copy of the Interview Summary form (PTOL-413/413b) should be given or mailed to the applicant (or applicant’s patent practitioner) along with any attachments.
The Interview Summary form shall include the date the interview was held and the substance of the interview shall be properly recorded. The applicant or the applicant’s patent practitioner, as appropriate, should be provided with a copy of the Interview Summary form either at the end of the interview or by mailing it to the applicant’s correspondence address either with or prior to the next official communication. A copy of the form may be faxed or, if the Office has appropriate authorization to conduct communications via the Internet, a copy of the form may be emailed to applicant (or applicant’s attorney or agent) at the conclusion of the interview. If additional correspondence from the examiner is not likely before an allowance or if other circumstances dictate, the Interview Summary form should be mailed promptly after the interview rather than with the next official communication.
The Interview Summary form provides for recordation of the following information:
In the case of an applicant-initiated interview, the Interview Summary form will include a reminder indicating it is the applicant’s responsibility to record the substance of the interview in the reply to an outstanding action or within the set period if no reply is outstanding. It is desirable that the examiner also orally remind the applicant of the applicant’s obligation to record the substance of the interview in each case where the interview was not initiated by the examiner. Where an interview initiated by the applicant results in the allowance of the application, the applicant is advised to file a written record of the substance of the interview as soon as possible making of record the items listed below to prevent any possible delays in the issuance of a patent.
The complete and proper recordation of the substance of any interview should include or be supplemented to include at least the following applicable items:
Examiners are expected to carefully review the applicant’s record of the substance of an interview. If the record is not complete or accurate, the examiner may give the applicant a 2-month time period to complete the reply under 37 CFR 1.135(c) where the record of the substance of the interview is in a reply to a non-final Office action.
The reply filed on [1] is not fully responsive to the prior Office action because it fails to include a complete or accurate record of the substance of the [2] interview. [3] Since the above-mentioned reply appears to be bona fide, applicant is given a shortened statutory period of TWO (2) MONTHS from the mailing date of this notice within which to supply the omission or correction in order to avoid abandonment. EXTENSIONS OF THIS TIME PERIOD MAY BE GRANTED UNDER 37 CFR 1.136(a) but in no case can any extension carry the date for reply to this letter beyond the maximum period of SIX MONTHS set by statute (35 U.S.C. 133 ).
1. In bracket 2, insert the date of the interview.
2. In bracket 3, explain the deficiencies.
Applicant’s summary of what took place at the interview should be carefully checked to ensure the accuracy of any argument or statement attributed to the examiner during the interview. If there is an inaccuracy and it bears directly on the question of patentability, it should be pointed out in the next Office communication from the examiner (e.g., rejection, interview summary, or notice of allowability), wherein the examiner should set forth an accurate version of the examiner's argument or statement.
If the record is complete and accurate, the examiner should electronically annotate the record with the indication "Interview record OK" on the paper recording the substance of the interview.
