This manual summarizes how deadlines are calculated for Saudi Arabian (SA) patent annuities and the key management points. In Saudi Arabia, annuities fall due each year based on the calendar year rather than on the filing anniversary, and once the grace period ends there is no restoration system. Managing these cases with the same instincts used for other countries can therefore throw the entire deadline schedule off, so this manual explains the anchor date, payment window, grace period and lapse item by item.

2. Anchor Date and Deadline Calculation
Saudi annuities are not counted from the filing anniversary. The reference is the calendar year. The annuity for that year falls due on January 1 each year, and March 31 is the regular payment deadline. Prepayment before January 1 is refused.
In other words, whatever the month and day of filing, the deadline itself is the same March 31 every year for all cases. There is no concept such as corresponding-date adjustment or end-of-month adjustment; instead, cases are managed with a fixed "1/1–3/31" window.
Here is a calculation example. For a case with a filing date of 2020-06-15 and a registration date of 2023-03-10, the deadlines are calculated as follows.
| Annuity year | Deadline |
|---|---|
| For year 2021 | 2021-03-31 |
| For year 2022 | 2022-03-31 |
| For year 2023 | 2023-03-31 |
| For year 2024 | 2024-03-31 |
| For year 2025 | 2025-03-31 |
| For year 2026 | 2026-03-31 |
| For year 2027 | 2027-03-31 |
| For year 2028 | 2028-03-31 |
Since this case was filed in 2020, payment starts with the annuity for the following year, 2021, and continues thereafter with a March 31 deadline each year for a total of 20 payments. The registration date (2023-03-10) is not used in the deadline calculation.
3. Start of Payment
- Payment starts from the year following filing.
- Regardless of whether the patent has been granted, payment is due every year even while the application is pending.
- Even if grant is delayed, the structure does not provide a separate retroactive lump-sum settlement procedure; the 1/1–3/31 window simply continues to roll around every year from the year after filing.
- The term is the filing date + 20 years, and there are 20 annuities in total.
Therefore, an in-house default flow of "start annuity management after grant" must not be applied as is. For Saudi cases, it is correct to set up the annuity schedule at the time of filing.
4. Grace Period and Surcharge
| Segment | Period | Amount payable |
|---|---|---|
| Regular payment window | 1/1 – 3/31 | Full amount of the relevant annuity |
| Grace period | 4/1 – 6/30 (3 months) | Double payment |
| After 6/30 | — | Automatic lapse |
The surcharge formula is not a progressive monthly scale but a flat doubling. The amount is the same whether you pay on April 1 or on June 30. The grace period is only three months — not the six-month grace period common in other countries.
5. Lapse and Restoration
This is why this manual is kept separate. In countries with restoration, missing the grace period ends as a cost issue, but in Saudi Arabia the right itself ends. Reminder lead times and urgency ratings must be set at the highest level.
6. Reductions
| Category | Rate |
|---|---|
| Corporate | Standard rate |
| Individual | 50% of the corporate rate |
| SMEs/universities | Separate reduction unconfirmed ⚠️ |
Reductions follow a two-tier structure, with individuals paying half the corporate rate. Separate reductions for SMEs or universities are an unconfirmed item, so it is safer not to base quotations on such eligibility and to use the corporate rate as the default.
Whether the right holder is an individual or a legal entity changes the rate to be billed, so verify before payment that the right holder classification in the case master matches reality. Billing at the wrong rate can disrupt payment processing, and because Saudi Arabia offers no means of restoration once a deadline is missed, the knock-on effect of misbilling is large.
7. Prepayment and Bulk Payment
- Prepayment before 1/1 is refused. Paying in advance in December of the preceding year does not work.
- Multi-year bulk payment is not possible. Payment can only be made one year at a time.
- Consequently, a payment cycle must be run once every year without fail between January and March.
A management approach of "bundling several years in advance to reduce reminders" cannot be applied to Saudi Arabia. Build the schedule on the premise that the same window will be handled every year for 20 years.
8. Official Fees
| Category | Amount (SAR) | Notes |
|---|---|---|
| Corporate, 1st year | 500 | Increases linearly each year thereafter |
| Corporate, 20th year | 10,000 | — |
| Individual | 50% of the corporate rate | Two-tier reduction |
9. Management Checklist
Items to check in the case docket
- Filing date: if this value is missing, the year in which the first annuity begins cannot be determined and the entire deadline schedule goes wrong. For Saudi cases, manage the filing date as a mandatory value.
- Whether the filing was in December: separately flag cases whose first annuity falls due immediately after filing.
- Whether pending applications are included: check that pre-grant cases have not been left out of the annuity schedule.
- Right holder classification (individual/corporate): this value determines the rate.
- Status of the appointed paying agent: for applications filed after 2023-12, only an agent of record with a POA can make payment, so confirm before the deadline that the power of attorney is valid.
- Right type classification: old GCC patents predating 2021-01-05 are managed separately on the GCCPO track, so keep them separate from the Saudi national patent schedule.
Annual payment cycle
- November–December of the preceding year: list the cases due for payment in the following year. Check whether new filings, particularly December filings, include a first annuity.
- December of the preceding year: check right holder classification and the status of the agent's power of attorney. Prepayment is not possible at this point, so only complete the preparations.
- Early January: annuities fall due. Issue bulk instructions to the agent and confirm the amounts.
- January–February: complete payment. Since the Eid holidays may overlap with the window at the end of March, make it standard practice not to defer to March.
- Mid-March: carry out a final check of any remaining unpaid cases. 3/31 is the last deadline in practice.
- 4/1–6/30: grace segment. Payment is doubled, and cases that enter this segment are managed and reported separately as incidents.
- After 6/30: there is no means of restoration. Treat unpaid cases as lapsed and record the cause.
In iphere's overseas annuity and renewal management, the appropriate approach is to create deadlines for Saudi cases as a fixed 3/31 window each year and to manage entry into the grace period as a separate alert. The key is to set generous reminder lead times on the premise that there are no office notifications.
Sources, cut-off date and disclaimer
This manual is based on iphere's August 2026 survey of country-by-country overseas maintenance rules, together with values produced by the deadline engine that runs on those same rules. Official fees and deadline rules change by office notice, so please confirm against the official source and your local agent before any actual payment or filing.
