Received a Decision of Refusal from the JPO? Your Three Options — Appeal (3 Months + 60 Days for Overseas Applicants), Pre-Appeal Reexamination, Divisional

A Decision of Refusal (拒絶査定) from the Japan Patent Office is not the end of the case, but it starts the shortest clocks in Japanese prosecution. Three routes are open: appeal, appeal with amendment leading to reexamination by the examiner, and a divisional application. This guide sets out the deadlines — including the ex officio extension overseas applicants receive — what each route allows you to change, and how they are combined in practice.

1. The Clock: 3 Months From Service, Plus 60 Days for Overseas Applicants

ActionPeriodBasis
Appeal against the decision3 months from service of the certified copyArt. 121(1)
— overseas applicantsEx officio extension of 60 daysArt. 4; Formality Examination Manual 04.10
— relief where the period was missed for reasons not attributable to the appellant14 days (overseas: 2 months) from the reason ceasing, within 6 months of expiryArt. 121(2)
Divisional application3 months from service of the first Decision of Refusal — deemed extended by the same period as any Art. 4 extension of the appeal period (overseas applicants: +60 days)Art. 44(1)(iii), 44(6)

Two clocks, not one

The appeal period (Art. 121(1)) and the divisional period (Art. 44(1)(iii)) are separate 3-month periods that start on the same day. When the JPO extends the appeal period for an overseas applicant under Art. 4, the divisional period is deemed extended by the same length (Art. 44(6)) — so both normally expire 3 months + 60 days from service. They are still two filings with two fees: diary both, and instruct Japanese counsel well before the date, because a divisional needs a Japanese-language specification and claims prepared in time.

2. Option 1: Appeal to the Trial and Appeal Department (Art. 121)

The appeal is heard by a panel of administrative judges, which reviews the decision anew. It is the route where the applicant maintains that the refused claims are allowable as they stand, or with an argument the examiner did not accept. If the panel finds a ground of refusal different from the examiner’s, it must issue a Notice of Reasons for Refusal and allow a response (Art. 159(2) applying Art. 50). Amendments at this stage are limited (Section 5).

3. Option 2: Appeal With Amendment → Pre-Appeal Reexamination (Arts. 162, 163)

If the appeal is filed together with an amendment of the description, claims or drawings, the JPO Commissioner must have an examiner reexamine the application before the panel is involved (Art. 162). The examiner applies the ordinary examination provisions (Art. 163) and may grant the patent outright. For the many refusals that turn on claim scope, this is the fastest route to allowance: the amendment answers the ground, the examiner allows, and the appeal never reaches a hearing. If the examiner maintains the refusal, the case goes to the panel.

4. Option 3: Divisional Application Within 3 Months (Art. 44(1)(iii))

A divisional filed within 3 months of service of the first Decision of Refusal is deemed filed on the parent’s filing date (Art. 44(2)). It is examined on its own claims and is not bound by the final-stage amendment limits that constrain the parent — but it may not add new matter relative to the parent’s original disclosure, and the parent’s refusal stands unless appealed. Divisionals are also available at any time an amendment could be made (Art. 44(1)(i)) and within 30 days after a decision to grant (Art. 44(1)(ii)). For overseas applicants, the 3-month period after a Decision of Refusal is deemed extended in step with the ex officio extension of the appeal period (Art. 44(6)).

5. What You May Amend at This Stage

An amendment filed with the appeal is confined to the four purposes of Art. 17-2(5) — deletion of a claim, limited restriction (same field, same problem), correction of clerical errors, and clarification of matters indicated in the Notice — and a restricted claim must be independently patentable (Art. 17-2(6)). A non-compliant amendment is dismissed (Art. 53 as applied by Art. 159(1)), and the appeal proceeds on the previous claims. The mechanics are explained in our new matter and final Office Action guide.

6. Choosing and Combining the Routes

SituationUsual route
A narrowing amendment within the four categories would answer the groundAppeal with amendment → reexamination (Option 2)
The examiner is simply wrong on the claims as they standAppeal on argument (Option 1), often with a fallback amendment
A different claim scope is wanted that would not qualify as limited restrictionDivisional (Option 3), frequently in parallel with an appeal
Japan is no longer worth the costLet the decision become final — but check the divisional window first if any scope has value

Before a Decision of Refusal is even issued, most of these outcomes can be shaped in the response to the Office Action — start with the Office Action hub and the inventive step guide.

Frequently Asked Questions

How long do I have to appeal a Decision of Refusal?
Three months from the date the certified copy of the decision was served (Art. 121(1)). For overseas applicants the JPO extends this period ex officio by 60 days under Art. 4 (Formality Examination Manual 04.10). If the period is missed for reasons not attributable to the appellant, the appeal may still be filed within 14 days — 2 months for overseas residents — from the date the reason ceased, and within 6 months after the period expired (Art. 121(2)).
What is pre-appeal reexamination?
If the appeal is filed together with an amendment of the description, claims or drawings, the JPO Commissioner must have the examiner reexamine the application (Art. 162). The examiner may then grant the patent without the case ever reaching a board — a fast and common outcome where the amendment answers the ground of refusal.
What can I amend when appealing?
Amendments filed with the appeal are subject to the same limits as after a final Notice: deletion of claims, limited restriction, correction of errors, clarification (Art. 17-2(5)), plus independent patentability of the restricted claim (17-2(6)). A non-compliant amendment is dismissed (Art. 53 as applied by Art. 159).
When can I file a divisional after refusal?
Within 3 months from service of the first Decision of Refusal (Art. 44(1)(iii)). The divisional is deemed filed on the parent’s filing date but may not contain new matter relative to the parent as originally filed. Where the appeal period is extended for an overseas applicant under Art. 4 (ex officio, 60 days), the 3-month divisional period is deemed extended by the same period (Art. 44(6)) — so in practice both clocks run 3 months + 60 days from service. If the period is missed for reasons not attributable to the applicant, a divisional may still be filed within 14 days (overseas: 2 months) of the reason ceasing, and within 6 months of expiry (Art. 44(7)).
Can I appeal and file a divisional at the same time?
Yes, and it is common: the appeal pursues the claims the applicant believes are allowable, while the divisional preserves a different claim scope — for example one that would not qualify as a limited restriction in the appeal.
