Response Deadlines and Extensions for Design Office Actions in Japan — A Guide for Foreign Applicants
2026.07.31
Tatsuyuki TSUBO
When the Japan Patent Office (JPO) issues a design Office Action (Notice of Reasons for Refusal), the applicant must respond by a set deadline. Foreign applicants — that is, applicants who are not resident in Japan — are given an initial response period of three months.
This period can be extended. At the examination stage, an extension is available without any specific reason. Even if the original deadline is missed, a late-filing extension of two months may still be possible. The two types of extension cannot be combined, so the maximum response period is five months.
At the appeal stage, only one extra month is available. Once that deadline has passed, no extension is possible.
One deadline cannot be extended at all: the period for filing an appeal against a decision of refusal. For designs this period is three months, even for foreign applicants. Patent practice is different here, so this point needs care.
This guide explains the current rules on response periods and extensions for foreign applicants filing design applications in Japan.
- Initial response period:
3 months at both the examination stage and the appeal stage - Examination stage:
Extension before the deadline: 2 months, no reason required, JPY 2,100
Extension after the deadline: 2 months, no reason required, JPY 7,200
The two extensions cannot be combined → maximum response period of 5 months - Appeal stage:
Extension before the deadline: 1 month only, no reason required, JPY 2,100
→ maximum response period of 4 months
No extension after the deadline - The period for filing an appeal against a decision of refusal is 3 months and cannot be extended, even for foreign applicants
1. Quick reference
The table below summarizes the rules on response period extensions for foreign applicants.
| Examination stage | Appeal stage | |
|---|---|---|
| Initial response period | 3 months | 3 months |
| Extension before the deadline | 2 months (1 request only) | 1 month (1 request only) |
| Valid reason | Not required | Not required |
| Extension after the deadline | Yes (2 months) | No |
| Can the two be combined? | No | — |
| Fee (before the deadline) | JPY 2,100 | JPY 2,100 |
| Fee (after the deadline) | JPY 7,200 | — |
| Maximum response period | 5 months | 4 months |

2. Response period for a design Office Action
When the JPO issues an Office Action, the applicant must respond within the period set by the examiner. For foreign applicants, the initial period is three months in each of the cases below.
| Type of notice | Initial response period |
|---|---|
| Office Action at the examination stage (national design application) |
3 months* |
| Notification of refusal (international design registration under Hague system) |
3 months |
| Office Action at the appeal stage (after appeal against decision of refusal has been filed) |
3 months* |
Initial response periods for foreign applicants
Under Formality Examination Manual 04.10 (section 2(2)), the three-month period is shortened to 40 days where the JPO considers that the local representative can prepare the document alone, without input from the applicant.
This shortening applies only to an Office Action on a national design application. It can apply at the examination stage and at the appeal stage alike. For a notification of refusal in a Hague application, the period is three months in every case and is not shortened on this ground.
In practice, a written opinion (arguments) normally needs instructions from the applicant, so three months is the usual period. Even so, always check the length of the period stated on the notice rather than assuming three months.
3. Extension at the examination stage
+
2 months
(1 request only)
+
2 months
Extension before the deadline
At the examination stage, no reason has to be given for an extension. The extension structure is as follows:
- Extension given: 2 months
- Number of requests: one only
- Valid reason: Not required
- Fee: JPY 2,100
- Maximum response period: 5 months
Note one difference from patent practice. For a patent, you can file a second request and gain one further month. For a design, only one request is allowed, and two months is the limit.
Extension after the deadline (Late-filing extension)
If the response deadline has been missed, a late-filing extension may still be available at the examination stage.
- Filing window: within 2 months from the day after the original deadline
- Extension given: 2 months from the day after the original deadline
- Valid reason: Not required
- Fee: JPY 7,200
- Number of requests: one only
When a late-filing extension is not available
The extension after the deadline is not available in the following cases.
- An extension was already given before the deadline. The two types of extension cannot be combined.
- A written opinion (arguments) was already filed within the initial period.
The rule refers only to a written opinion. An amendment does not have the same effect: if the applicant filed only an amendment within the initial period, and no written opinion, an extension after the deadline is still available. This treatment has been confirmed with the JPO.
Comparing the two extension patterns
Because the two types of extension cannot be combined, you have to choose one of them.
Both patterns result in five months in total. The fee is different, and Pattern B costs more than three times as much. For most cases, the safer approach is to plan around the initial three months, or around a period extended by a request filed before the initial deadline (Pattern A). Pattern B is best kept as a fallback for when more time proves unavoidable.
| Pattern A Before only |
Pattern B After only |
|
|---|---|---|
| Initial period | 3 months | 3 months |
| Before deadline | +2 months | — |
| After deadline | — | +2 months |
| Maximum response period | 5 months | 5 months |
| Fee | JPY 2,100 | JPY 7,200 |
| Condition | — | No extension request and no written opinion within the initial period |
The two extension patterns give the same total period
4. Extension at the appeal stage
+
1 month
(1 request only)
Where an Office Action is issued after an appeal against a decision of refusal has been filed, the rules are stricter than at the examination stage.
- Extension given: 1 month (maximum)
- Valid reason: Not required
- Fee: JPY 2,100
- Extension after the deadline: Not available
- Maximum response period: 4 months
Because no extension is available once the deadline has passed, deadline management at the appeal stage needs to be considerably tighter than at the examination stage. The practical maximum is four months, and there is no safety net beyond it.
(Reference) The period for filing an appeal against a decision of refusal cannot be extended
→
No extension
An appeal against a decision of refusal must be filed within three months from the day after the certified copy of the decision is served. This period is set by law and cannot be extended. The JPO will not extend it on its own initiative either.
A relief provision does exist under Article 46(2) of the Design Act for cases where the deadline was missed for reasons beyond the applicant’s control. However, the requirements are strict, and it is not a substitute for ordinary deadline management.
