FOR FOREIGN PATENT COUNSEL & IN-HOUSE IP TEAMS
Japan Patent Office Action Response
& PCT National Phase Entry
Fixed-fee handling of Japanese national phase entries, Notices of Reasons for Refusal, Decisions of Refusal and missed-deadline restorations — reported in English by JPA-registered patent attorneys (benrishi).
Which situation are you in?
Japanese patent prosecution has short, non-extendable-looking deadlines that are in fact extendable — and generous-looking periods with hidden traps. Pick the situation that matches your file; each card links to our detailed guide.
🗓️
Entering the Japanese national phase
- 30 months from the priority date; national form plus Japanese translation
- Translation special period of 2 months if the national form is filed within the last 2 months
- Multi-multi claims must be restructured for international filing dates on or after April 1, 2022
- Examination request within 3 years of the international filing date
📨
Received a Notice of Reasons for Refusal
- 3 months from dispatch for overseas applicants (60 days domestic)
- Extensions before and after expiry (see table below)
- Response by ground: inventive step, new matter, Art. 36, eligibility, multi-multi
- After a "final" notice, amendments are limited to four categories
⚖️
Received a Decision of Refusal
- Appeal within 3 months + 60 days ex officio for overseas applicants
- Appeal with amendment → pre-appeal reexamination by the examiner
- Divisional within the same period (extended in step, Art. 44(6))
🚨
Missed a deadline / no Japanese representative
- Restoration under the "unintentional" standard since April 2023: 2 months from discovery, within 1 year, JPY 212,100
- Patent administrator must be appointed within 3 months after the national processing standard time
- JPO notice → 2 months → deemed withdrawal if still unappointed

Two clocks after a Decision of Refusal
The appeal and the divisional are separate filings with separate fees, even though the periods coincide. Send us the notice and we will compute both dates from the service date and confirm them in writing before you docket.
How we work with foreign counsel
What to send us
You can upload the notice directly in the form below. The more of the following we receive, the more precise the first reply:
- The JPO notice (PDF) — Notice of Reasons for Refusal, Decision of Refusal, or the notice to appoint a patent administrator
- Application number or PCT number, and the date on the notice
- The claims currently on file in Japan and the original-language claims
- Cited documents, if you already have them, and any response filed in another jurisdiction on the same family
- Your preferred outcome (broad claims vs. quick allowance) and any budget limit
What you receive within one business day
The deadline as we compute it (including extension routes), the grounds in plain English, our recommended option and alternatives, and a fixed-fee quote. No charge for the assessment.
Fees
Attorney fees are quoted as a fixed amount per response, appeal or entry after we have read the notice and the claims on file. JPO official fees are charged at cost; the amounts most often relevant to overseas applicants are the extension fees (JPY 2,100 before expiry; JPY 51,000 after expiry) and the restoration fee (JPY 212,100). For national phase entry, our cost breakdown is published in the national phase entry cost guide; for examination-fee reductions available to foreign SMEs and universities, see the power of attorney, official fees and fee reductions guide.
