Examiner Interviews: The Most Underused Step in Prosecution

What an Interview Actually Is

The request itself is administrative: a short form or letter naming the application, proposing two or three dates, and stating the matters to be discussed. Scheduling usually lands within two to four weeks. The examiner attends, and where the examiner is relatively junior a supervisor or a primary examiner attends as well, because the authority to agree an allowance sits with a signatory.

An agenda is submitted in advance — one page, three topics at most, with any proposed claim amendments attached in marked-up form. Examiners consistently report that the agenda is the single factor determining whether the half hour is useful, because it lets them re-read the relevant passages of the cited art before the call rather than during it.

Afterwards, a written record is mandatory. The examiner enters an interview summary on the file, and the applicant is normally required to file a statement of the substance of the discussion within a set period, typically one month. That record is public and permanent, which is the central discipline governing how the conversation should be conducted.

Duration

Commonly thirty minutes; longer sessions are granted where the agenda justifies them.

Cost

No official fee in most systems; the only expense is preparation and attendance.

Record

A written summary is entered on the public file by both sides; nothing said is off the record.

The Window Where It Is Worth Most

The highest-value moment is narrow: after the first action has issued and before the written reply is filed. At that point the examiner has articulated a position but has not yet defended it in writing, the applicant has not yet committed to an argument, and a single conversation can determine which of three possible replies is worth drafting. An interview held here regularly saves an entire round.

A first interview after the first action is granted essentially as a matter of course. Interviews before any action has issued are discretionary and less common, though some offices operate programmes allowing an early conversation about the search and the claim scope in exchange for the applicant accepting certain limits on claim numbers.

After a final rejection the position changes. An interview is then entirely at the examiner's discretion and is usually granted only where the applicant has something concrete to propose — specific amendment language, not a restatement of the argument already rejected. Where it is granted, it is often the cheapest available route out of a case that would otherwise go to appeal or to a request for continued examination, both of which cost real money.

Thirty minutes before the reply is drafted is worth more than three months of drafting after it.

On when to make the request

Why a Conversation Outperforms a Brief

Most disagreements in prosecution turn out to be one of two things, and written correspondence is bad at telling them apart. Either the examiner believes the cited document genuinely discloses the claimed element — a substantive dispute — or the examiner is reading the claim language differently from the way the drafter intended, which is a wording problem that can be fixed in a sentence. A brief addresses both identically. A single question — which passage of the reference do you read as teaching the biasing element of claim one? — separates them in under a minute.

The second thing an examiner interview does is let language be tested before it is committed. An applicant can propose a limitation verbally and hear whether it would overcome the rejection. Examiners frequently indicate that a particular addition would place the case in condition for allowance. Nothing said is binding until it appears in a written action, and the caveat is always stated, but the information is unavailable by any other means at any price.

The measurable effect is consistent: applications in which an interview takes place tend to resolve in fewer actions and reach allowance sooner after the following reply than comparable applications prosecuted purely on paper. Part of that is selection — applicants who request interviews are engaged applicants — but part of it is simply that the examiner is a person with a docket, a recorded time allowance per case and an interest in disposing of files cleanly. A well-run conversation serves that interest.

How to Run the Half Hour

Preparation is almost the whole of it. Choose one claim — normally the broadest independent claim — and one rejection. Identify the single element you believe the cited document does not disclose, and have the passage of the document in front of you in the examiner's own words. Draft two alternative amendments, one narrow enough that you expect it to be accepted and one you would prefer, and attach both to the agenda.

In the conversation, ask before arguing. Establish what the examiner's reading is, confirm it back, and only then explain why the claim requires something the document does not provide. Quote the reference rather than characterising it. Where the examiner concedes a point, say so aloud and note it, because you will be writing the summary.

Four things waste the time. Reading the written brief aloud, which the examiner has already read. Arguing commercial value, investment or market need, none of which correspond to any test being applied. Bringing five rejections to a thirty-minute call. And treating the examiner as an adversary, when the examiner's own performance is measured in part by clean, defensible dispositions rather than by refusals.

Close by summarising: what was agreed, what remains disputed, and what will be filed. Then file the summary promptly and accurately. An inaccurate summary is worse than none, because the examiner must correct it on the record, and the correction is the first thing anyone reading the file later will notice. The same discipline that produces a good written reply, described in the account of how an office action is answered, produces a good interview.

What the Record Does Later

Everything entered on the file becomes part of the prosecution history, and prosecution history is read years later by people looking for a reason the claims should be construed narrowly. A statement made in a room to move a case forward — that the invention is really about a particular configuration, that a term should be understood in a specific restrictive sense — can be quoted back with considerable force in a dispute over infringement.

The working rule follows directly: concede procedure freely and scope never. Agree to file an amendment; do not agree that the claim was always limited to what the amendment now says. Be precise about what a term means; avoid volunteering what it excludes. And accept that an examiner may raise a new ground during the conversation, which is not bad faith but a consequence of the file being reconsidered — it is better to hear it now than in a third action.

None of this argues against the step. It argues for preparing it as carefully as a written filing, because it carries the same permanence. Set against the alternative — two more rounds, six to twelve further months and the fees attached to them — a single well-prepared examiner interview is the best-value half hour available in the whole process. Seen from the other side of the desk, as the account of how an examiner reads an application sets out, it is also the only point at which the applicant stops being a document and becomes a person with a question.

That shift matters more than it sounds. What is being protected is a right to exclude others rather than a licence to sell, and its eventual breadth is decided in exchanges exactly like this one. Accounts of independent inventors making that passage — how speculative fiction shapes what people attempt to build, how an idea travels from sketchbook to finished object, and the inventors behind the MixAid device — all describe the same unremarkable turning point: the moment someone finally explained the invention to the person deciding its fate.

Concede procedure freely. Concede scope never. Everything said is on the file forever.

The rule that governs the conversation

An interview is not a favour granted to persistent applicants. It is a designed part of the process, sitting unused in most files, waiting on a one-page request.
