Patent annuity management is the work of paying every renewal fee, in every office, on time, and deciding each year which patents are still worth paying for. Across 25 countries that means different due dates, grace periods, surcharges, currencies and local agents, and one missed payment can put an invention into the public domain. This guide is for companies with patent families spread across Europe, Latin America and Africa that want to centralise payments without losing control of the decisions.
Key takeaways
- The Paris Convention guarantees at least six months of grace for late maintenance fees, usually with a surcharge, but each country sets its own rules on what happens next.
- Due dates are not uniform: the EPO, Spain and the Andean Community tie them to the month of the filing anniversary, while Brazil gives a three-month payment window at the start of each patent year.
- Annuities often fall due before grant: European applications pay from the third year, and Spanish and Brazilian applications accumulate fees that must be settled on grant or national entry.
- Restoration after a lapse exists in some countries (Spain, Brazil, Mexico) but is limited in time and, in Spain, cannot be used against third parties who started using the invention in good faith in the meantime.
- Centralising payments works only if one team also owns the renew-or-abandon decision for each patent and each country.
What is patent annuity management and why do patents lapse?
Almost every patent office charges an annual fee (an “annuity” or “renewal fee”) to keep an application or patent alive. The obligation runs for the life of the right, normally 20 years from filing, and the amounts rise over time. Patent annuity management covers the calendar, the instructions to pay, the payment itself, the receipt and the yearly review of whether each patent still earns its cost.
The international floor is set by Article 5bis of the Paris Convention: member countries must allow a grace period of not less than six months to pay maintenance fees, subject to a surcharge if national law provides for one, and they may (but need not) allow the restoration of patents that lapsed for non-payment. Everything beyond that minimum is national law, which is why a portfolio across Europe, Latin America and Africa cannot be run on a single rule of thumb.
In practice, patents rarely lapse because nobody wanted to pay. They lapse because the reminder went to an old address, the local agent was waiting for instructions, the owner changed after a restructuring or the budget holder assumed someone else had paid.
How do annuity rules differ across the corridor?
The table summarises the rules we work with most often, taken from the legal texts listed in the sources.
| Office | When annuities fall due | Late payment | After the grace period |
|---|---|---|---|
| EPO, European patent application | From the 3rd year; last day of the month of the filing anniversary. The 3rd-year fee can be paid up to six months early, the others up to three months (Rule 51(1) EPC) | Six months with an additional fee of 50% of the late fee (Rule 51(2) EPC; Rules relating to Fees) | Application deemed withdrawn (Article 86 EPC); only re-establishment of rights under Article 122 EPC remains |
| EPO, Unitary Patent | Years after the mention of grant; last day of the month of the filing anniversary; up to three months early (Rule 13 UPR) | Six months with an additional fee | Patent lapses in all participating states at once |
| Spain (OEPM) | Accrual on the last day of the month of the filing anniversary; payment within three months of accrual. Fees accrued before grant are paid within three months of the grant publication (Article 184, Patents Act 24/2015) | 25% surcharge in the first three months, 50% in the next three (Article 185) | Lapse (Article 108); restoration request within 12 months of the end of the surcharge period, showing all due care (Article 53) |
| Brazil (INPI) | From the start of the 3rd year from filing; payment in the first three months of each patent year (Article 84, Law 9.279/1996) | Six further months with an additional fee | Application archived or patent extinguished; restoration within three months of the notice, with a specific fee (Articles 86 and 87) |
| Mexico (IMPI) | Annual fees throughout the 20-year term (Article 53, LFPPI); grant requires paying the title fee and that year’s annuity within two months (Article 110) | Six-month grace period (Article 160) | Lapse without any declaration; rehabilitation within the following six months, paying the fee plus surcharges (Article 161) |
| Argentina (INPI) | Annual maintenance fees on the dates set by the office | 180 days to pay the updated fee (Article 62(c), Law 24.481) | Lapse, unless non-payment was due to force majeure |
| Andean Community (Colombia, Peru, Ecuador, Bolivia) | Paid in advance; due on the last day of the month of filing; several years can be paid early (Article 80, Decision 486) | Six months with a surcharge; the right stays fully in force meanwhile | Lapse by operation of law |
In Africa, the regional systems (ARIPO and OAPI) and each national office apply their own renewal regimes, and validations of European patents in Morocco and Tunisia follow local rules. Brazil adds a structural requirement: under Article 217 of Law 9.279, a foreign holder must appoint and keep a qualified attorney domiciled in Brazil, and failing to do so is itself a ground for extinction (Article 78).
Why centralise patent annuity management?
A portfolio with a Unitary Patent, Spanish validations, and national patents in Brazil, Mexico and Colombia already runs on five legal regimes, several currencies and at least three local agents. Centralisation brings four concrete benefits:
- One calendar built on each office’s logic, not on a single anniversary date. Brazil’s three-month window, Mexico’s payment at grant and Spain’s deferred pre-grant fees all need their own rule.
- One decision point. Each payment is preceded by a question: does this patent, in this country, still protect revenue, block a competitor or support a licence?
- Consistent ownership records, so that renewals are paid for the right holder after mergers, assignments or internal restructurings.
- Comparable costs. Official fees can be budgeted family by family and country by country, which makes abandonment decisions rational rather than reactive.
How to set up centralised patent annuity management
- Inventory. List every family, country, application or patent number, filing date, owner of record and current agent.
- Verify legal status at each office. Do not rely only on internal records: check that every right is still in force and that no fee is already in its grace period.
- Map the rules per country: due date basis, early payment window, grace period, surcharge and restoration options.
- Set a decision calendar three to four months before each due date, so that abandonment is a choice, not an accident.
- Define payment channels (direct or through a local agent, depending on the country), give written instructions and keep the receipts.
- Review once a year against the business plan, and recover any reductions available, such as the 50% reduction on the third to fifth annuities for Spanish national patents filed by entrepreneurs and SMEs (Article 186, Patents Act 24/2015).
What this means for your business
- Treat annuities as decisions, not invoices. The cheapest renewal is the one you deliberately stop paying.
- Do not plan on grace periods. They are a safety net with surcharges, and some systems give no second chance afterwards.
- Budget for pre-grant fees in Europe and Brazil, and for the payment due at grant in Mexico and Spain.
If you want this handled for you, our team for international patent prosecution and annuity management can take over the calendar, the payment instructions and the local agents. For groups planning acquisitions or licences, it fits within a wider cross-border IP strategy and portfolio review.
Where companies lose patents over annuities
- Using the grace period as the real deadline. A payment made in the last week of the grace period leaves no room for a bank error or a wrong reference.
- Forgetting pre-grant fees. A European application that is deemed withdrawn for an unpaid third-year fee never reaches grant.
- Copying one country’s calendar to another. Brazil’s window opens at the start of each patent year; the EPO and Spain run from the month of the anniversary.
- Counting on restoration. In Spain, a restored patent cannot be enforced against a third party who began using the invention in good faith between the lapse and the publication of the restoration (Article 53(6)).
- Paying on autopilot. Annuity providers pay what they are told; without an annual review, the budget goes to patents that no longer protect anything.
Frequently asked questions
What happens if a patent annuity is paid late?
Most offices allow a grace period of at least six months, as required by the Paris Convention, usually with a surcharge. The EPO charges 50% of the late fee; Spain applies 25% in the first three months and 50% in the next three. If the grace period passes without payment, the patent or application lapses, and only some countries allow restoration.
Can a lapsed patent be restored?
Sometimes. Spain allows restoration within 12 months of the end of the six-month surcharge period if the owner shows all due care; Brazil within three months of the notice of extinction; Mexico within six months after the grace period. Restoration is not guaranteed, has its own fees and may be limited by rights acquired by third parties in good faith.
Do I pay annuities while the application is still pending?
In many systems, yes. A European application pays renewal fees to the EPO from the third year until the year the grant is published. Brazil charges annuities on applications from the third year, and Spain collects fees accrued before grant within three months of the grant publication. Budgets that start at grant are usually wrong.
