For foreign IP counsel protecting product designs in Japan, the Japanese design patent system...
Managing annuities (maintenance fees) for Japanese patents requires precise tracking of due dates, claim-count-based fee tiers, and surcharge rules. For foreign IP counsel and corporate IP teams, missed annuity deadlines can mean permanent patent loss. This guide covers the JPO annuity schedule, fee structure, payment options, surcharge windows, and Evorix's managed annuity service for foreign clients.
Key Takeaways
- Annuities start from year 4; years 1–3 are paid as a lump sum at grant
- JPO fees scale with claim count and year tier (4–6, 7–10, 11–15, 16–20)
- Annuity due date: anniversary of grant each year
- Grace period: 6 months with surcharge (up to 2x normal fee)
- Restoration after lapse: 1-year window under "due care" standard
- License-of-Right (Article 23) declaration halves annuity fees
- Evorix offers managed annuity service: $120–280 per year per patent with deadline guarantee
Table of Contents
1. Japan Annuity System Overview
Japanese patents require annual maintenance fees (annuities) starting from year 4 onwards. Failure to pay results in patent lapse (forfeiture of rights). Foreign patent owners must designate a Japanese patent attorney (benrishi) as the official representative for annuity payments and JPO communications.
Key principles:
1. Years 1–3 are paid as a single lump sum at grant registration
2. Years 4–20 are paid annually, with due date on the anniversary of the patent registration date
3. Annuity fees increase substantially in later years to encourage release of unused patents
2. JPO Annuity Fee Schedule
JPO publishes the fee schedule in the Patent Act and Rules. Annuity fees consist of a base fee plus a per-claim fee, varying by year tier:
| Year Tier | Base Fee (JPY) | Per-Claim Fee (JPY) | Annual fee (15 claims) |
|---|---|---|---|
| Years 1–3 (lump sum at grant) | 2,100 × 3 | 200 × 3 per claim | JPY 15,300 |
| Years 4–6 | 8,400 per year | 800 per claim per year | JPY 20,400 per year |
| Years 7–10 | 21,800 per year | 2,100 per claim per year | JPY 53,300 per year |
| Years 11–15 | 60,800 per year | 5,900 per claim per year | JPY 149,300 per year |
| Years 16–20 | 173,300 per year | 17,200 per claim per year | JPY 431,300 per year |
| Total 20 years (15 claims) | — | — | JPY 3,478,000 (~$23,200) |
3. Claim-Count-Based Calculation
The per-claim fee structure means claim count materially affects long-term cost. A 30-claim patent costs nearly 2x the annuities of a 15-claim patent over 20 years.
Example comparison:
10-claim patent: ~JPY 2,478,000 (~$16,500) over 20 years
15-claim patent: ~JPY 3,478,000 (~$23,200) over 20 years
20-claim patent: ~JPY 4,478,000 (~$29,900) over 20 years
30-claim patent: ~JPY 6,478,000 (~$43,200) over 20 years
Strategic implication: Reducing claims at examination request stage (under Japanese multi-multi claim rules and through targeted amendments) directly reduces 20-year maintenance cost. Consider claim consolidation strategies during prosecution.
4. Payment Timing & Anniversary Rule
Annuity payment is due on the anniversary of the patent registration date. Example: a patent registered on March 15 has annuity due on March 15 each year.
Payment can be made up to 12 months before the due date — meaning you can pre-pay early without penalty (though prepayment forfeits flexibility if you later abandon).
5. Grace Period & Surcharge
If you miss the due date, JPO provides a 6-month grace period with surcharge:
| Days Past Due | Surcharge | Fee Multiplier |
|---|---|---|
| Day 1–30 (within 1 month) | 0% | 1.0x normal fee (no surcharge but late filing required) |
| Day 31–180 (within 6 months) | 100% surcharge | 2.0x normal fee |
| Day 181+ (lapsed) | Patent forfeited | Restoration only by "due care" standard |
Critical deadline awareness: After 6 months past due, the patent is permanently lapsed. Restoration requires proving "due care" was taken — a very high standard. JPO has been strict in recent years on restoration applications.
6. Lapse and Restoration
If a patent lapses due to non-payment, restoration is possible within 1 year from the original due date under Article 112 of the Patent Act, but only under the strict "due care" standard.
Restoration requirements:
1. Petition filed within 1 year of original due date
2. Detailed evidence that "due care" was exercised
3. Reasonable explanation for the missed payment
4. JPO discretion
Restoration is granted in ~30% of petitions — meaning 70% of lapses become permanent.
7. License-of-Right (Half Fee Option)
Article 23 of the Patent Act allows the patentee to declare a "license of right" — agreeing to license the patent to anyone on reasonable terms. In exchange, annuity fees are reduced by 50%.
Strategic considerations:
- License-of-right declaration is irrevocable (cannot be withdrawn easily)
- The declaration applies to the entire patent (cannot be selective)
- Suitable for: long-tail patents being kept alive for defensive use
- Not suitable for: actively licensed patents, strategic SEPs
8. Multi-Year Prepayment
You can prepay multiple years' annuities in a single payment. This is administratively convenient and immune to short-term tax/finance issues, but:
Pros:
- Reduces processing fees and administrative overhead
- Eliminates risk of missed deadlines
- Simplifies budgeting
Cons:
- Forfeits flexibility if you decide to abandon
- Cash flow impact (large upfront payment)
- JPO does not refund prepaid annuities upon abandonment

10. Total 20-Year Annuity Cost
Combined JPO + attorney costs for a typical 15-claim patent over 20 years:
| Item | 20-Year Cost (USD) |
|---|---|
| JPO annuity fees (15 claims) | ~$23,200 |
| Attorney service (Evorix Standard) | ~$3,400 ($170 × 20 years) |
| Total maintenance cost | ~$26,600 |
| Cost reduction with License-of-Right | −$11,600 (50% off annuities) |
| Cost reduction by claim reduction (10 claims) | −$6,700 (smaller annuities) |
Frequently Asked Questions
Q. When is the first annuity due in Japan?
A. Years 1–3 are paid as a lump sum at patent grant. The first annual payment is for year 4, due on the 4th anniversary of the patent registration date.
Q. What happens if I miss a Japan annuity deadline?
A. JPO provides a 6-month grace period with 100% surcharge. After 6 months, the patent is permanently lapsed. Restoration is possible within 1 year under "due care" standard but is granted in only ~30% of cases.
Q. Can I pay annuities in advance for multiple years?
A. Yes. You can prepay multiple years of annuities in a single payment. This simplifies administration but forfeits flexibility if you later decide to abandon the patent.
Q. How does claim count affect annuity cost?
A. JPO annuities have a per-claim component that scales significantly in later years. A 30-claim patent costs nearly 2x a 15-claim patent over 20 years. Claim reduction during prosecution is a cost-control strategy.
Q. What is a license-of-right declaration?
A. Under Article 23, the patentee can declare willingness to license to anyone on reasonable terms, in exchange for 50% annuity fee reduction. This is irrevocable and applies to the entire patent.
Q. Can Evorix handle annuities for patents originally filed by other firms?
A. Yes. We routinely take over annuity management from other firms. Transfer requires updating the address for service and Power of Attorney filings, which we handle.
