How to File a Patent in Italy: 3 Proven Routes (2026)

Italy is the European Union’s third-largest economy and a manufacturing powerhouse in machinery, fashion, automotive and pharmaceuticals, which makes it a jurisdiction few serious filing strategies can skip. Yet its patent system has quirks that catch foreign applicants off guard — not least a national PCT route that was closed for years and only reopened in 2020. If you are working out how to file a patent in Italy, you have three genuine routes: a national application at the UIBM, validation of a granted European patent, or entry into the Italian national phase of a PCT application. This guide walks through each route, the search report the EPO prepares for Italian filings, the deadlines you cannot miss, and how an Italian patent is enforced.

How to File a Patent in Italy: The Three Routes

There is no single door into the Italian system — there are three, and the right one depends on where else you want protection. The decision is best made before a single fee is paid, because switching routes later usually means starting over.

1. National route: file directly at the UIBM (Ufficio Italiano Brevetti e Marchi) for protection in Italy only.
2. European route: obtain a European patent from the EPO, then validate it in Italy.
3. PCT national phase: file an international application and enter the Italian national phase directly — an option only for PCT applications filed on or after 1 July 2020.

Whichever door you use, the substance is the same: an Italian patent runs for a maximum of 20 years from its filing date and is enforced in the Italian courts and, for European patents, potentially through the Unified Patent Court. Italy is a member of both the European Patent Convention and the UPC — a combination that shapes every route below.

Filing a National Patent at the UIBM

A national application is filed with the UIBM, either through the ministry’s online portal (a digital signature is required) or via a Chamber of Commerce, and must contain a request, a description, one or more claims, any drawings and an abstract. The official language is Italian; documents filed in another language must be followed by an Italian translation within two months.

Here is the point most foreign applicants miss. Since a long-standing arrangement between Italy and the EPO, the European Patent Office draws up the search report for Italian national applications — and it does so free of charge to the applicant. The report, with a written opinion on novelty, inventive step and industrial application, typically arrives within six to nine months of filing and gives an early, candid read on whether the invention is likely to survive.

Grant usually takes two to three years. Annual maintenance fees (annuities) fall due from the third year and rise over the life of the patent, ranging from roughly €60 in the early years to several hundred euros later on. Missing an annuity is one of the quietest ways an Italian patent lapses.

Validating a European Patent in Italy

Most foreign applicants reach Italy not through a national filing but by validating a European patent. Once the EPO grants, you designate Italy and complete the national validation: a full Italian translation of the granted patent must be filed with the UIBM, together with the prescribed fee, within three months of the date the grant is mentioned in the European Patent Bulletin.

Italy is not among the countries that waived translation under the London Agreement, so the translation cost is real and should be budgeted. If you are weighing this path, our guide to European patent validation explains the deadlines and translation rules country by country.

Since 1 June 2023 there is also the unitary patent: a single right covering the participating UPC states, including Italy, obtained by a request for unitary effect within one month of grant. It removes the per-country validation for those states but commits the patent to the UPC for its whole life, with no opt-out.

The PCT National Phase — Reopened in 2020

For years Italy had no direct PCT national phase at all: an international application could reach Italy only through the European regional phase, by entering the EPO and then validating the resulting European patent. That changed for PCT applications filed on or after 1 July 2020, which may now enter a direct Italian national phase as an alternative to the Euro-PCT route.

The deadline for the direct Italian national phase is 30 months from the earliest priority date — one month earlier than the 31-month deadline for the European regional phase, a difference worth diarising carefully. A full Italian translation of the specification must be filed on entry or within two months afterwards.

One caveat that still trips people up: the direct route applies only to PCT applications with a filing date on or after 1 July 2020. For any international application filed before that date, Italy can still be reached only through the Euro-PCT regional phase at the EPO. Check the international filing date before you assume the national route is open.

Costs, Deadlines and Common Mistakes

The cost of filing a patent in Italy depends almost entirely on the route. A national UIBM filing is comparatively inexpensive — the EPO search comes free — while the European and unitary routes carry EPO fees and, for classic validation, translation costs. Professional representation is required for applicants without a residence or place of business in Italy.

• Priority: claim Paris Convention priority within 12 months of your first filing.
• PCT direct national phase: 30 months from priority (post-1 July 2020 PCT filings only).
• European regional phase: 31 months from priority at the EPO.
• EP validation in Italy: Italian translation filed within 3 months of grant.
• Annuities: due from the third year and rising thereafter.

The mistakes we see most often are assuming a direct national phase exists for an older PCT application, forgetting that Italy still requires a full translation on EP validation, and letting the 30-versus-31-month deadline gap cause a missed entry. A short jurisdictional check at the outset avoids all three.

How an Italian Patent Is Enforced

National Italian patents are enforced before the specialised business divisions (sezioni specializzate in materia di impresa) in Milan, Turin and Rome, which handle infringement, validity and preliminary injunctions. Italian courts are experienced with cross-border disputes and can grant descriptions and seizures to secure evidence and stop infringing goods.

For European and unitary patents, the Unified Patent Court also reaches Italy. Milan hosts the third seat of the UPC’s central division, which opened in June 2024 and hears cases in IPC section A (human necessities, including much of pharma and life sciences), while patents covered by a supplementary protection certificate are handled in Paris. A UPC local division also sits in Milan. If you are litigating locally, see our specialists for patent invalidation in Milan and Turin, and the broader Italy services hub.

Filing strategy in Italy therefore cannot be separated from enforcement strategy: the unitary route buys breadth but locks you into the UPC, while classic national validation keeps disputes in the Italian courts and preserves the opt-out. Compare the approach with our guide to filing a patent in France, another core UPC jurisdiction.
