Prior Art Litigation Search in Turin.

A prior art search Turin litigation counsel can rely on has to match where the fights actually start — and in the Piedmontese capital that means automotive engineering, powertrains, industrial design and aerospace. Turin is the historic home of the Italian car industry, from Stellantis and Fiat at Mirafiori and Lingotto to FPT Industrial, Italdesign and Pininfarina, and it has become one of Europe’s densest aerospace clusters around Avio Aero, Thales Alenia Space and Leonardo. When those portfolios are asserted, the validity fight is heard by the specialised business court in Turin, or — for European patents with unitary effect — before the Unified Patent Court in Milan. PerspireIP builds invalidity-grade searches for the parties challenging those patents before the Italian courts, the UPC and the EPO.

Where a prior art search Turin case is actually heard

Italian patent litigation is concentrated before a small number of specialised business courts, the sezioni specializzate in materia di impresa — often called the tribunale delle imprese — and Turin operates one of them. The Sezione Specializzata in materia di Impresa of the Tribunale di Torino hears patent infringement and nullity actions, and its territorial reach covers the Piedmont region and Valle d’Aosta. Where the accused party is based in the industrial belt around Turin, this is the forum in which validity is decided.

Venue in Italy follows the defendant. Under the ordinary rule of forum rei, an action is brought where the defendant is resident or domiciled, so a claim against a Turin-based carmaker, supplier or engineering firm lands in Turin. If the defendant has no seat in Italy the case can proceed where the plaintiff sits, and if neither party is domiciled in Italy the Court of Rome takes jurisdiction. That structure means an accused party’s home base largely dictates the venue, and Turin’s docket is shaped by the companies clustered around it.

Two features of Italian procedure matter for how prior art is used. Unlike the German model, the Italian court does not bifurcate: validity and infringement are decided together in a single proceeding, so the invalidity attack has to be trial-ready from the outset. And the court almost always appoints a consulente tecnico d’ufficio (CTU), an independent technical expert whose report on novelty and inventive step heavily influences the outcome. Prior art that is charted, dated and ready to put in front of that expert is what moves an Italian nullity case.

• Tribunale di Torino, Sezione Specializzata in materia di Impresa — the specialised business court for patent infringement and nullity across Piedmont and Valle d’Aosta
• Single, unbifurcated proceeding — validity and infringement decided together, so invalidity art must be trial-ready from day one
• Court-appointed technical expert (CTU) — an independent expert whose novelty and inventive-step findings drive the decision
• Unified Patent Court, Milan — the route for unitary patents and non-opted-out European patents, sitting in Milan rather than Turin

Turin’s UPC choice sits in Milan, not Turin

Italy is a founding member of the Unified Patent Court, and that changes the map for a Turin dispute — but the UPC does not sit in Turin. Italy’s UPC presence is entirely in Milan, which hosts both a Local Division (open since the court’s June 2023 launch) and, since June 2024, a section of the Central Division. For a patent asserted against a Turin company, that means the choice is between the national Impresa court in Turin and the UPC in Milan, depending on the patent’s status.

What the Milan Central Division hears is defined by technology. When the UK dropped out of the UPC, the competences of the former London section were reallocated, and Milan took IPC section A (human necessities), excluding Supplementary Protection Certificates. Revocation actions against SPCs and their basic patents go to the Paris seat, while chemistry and mechanical-engineering revocations sit in Munich. A Turin accused party weighing a central revocation therefore has to map the asserted patent to the right seat before filing.

The national route has not disappeared. A classic European patent can be opted out of the UPC, in which case it is litigated only before the Italian courts, and Italian national patents granted by the UIBM never fall under UPC jurisdiction at all. So a Turin dispute can run in three different forums — the Tribunale di Torino, the Milan Local Division, or the Milan Central Division — and each applies the same core validity grounds of novelty and inventive step. Prior art scoped to the forum that will actually decide the case is what wins it, whichever venue the parties end up in.

Automotive engineering: where Turin’s patent fights start

Turin is the cradle of the Italian automobile. Stellantis runs its historic Italian operations here, from the Mirafiori complex to the Lingotto landmark, and the wider ecosystem includes FPT Industrial’s powertrains, the design and engineering houses Italdesign and Pininfarina, and a deep tier of component and tooling suppliers. That concentration produces a steady stream of mechanical, powertrain, electronics and design patents — and, when they are asserted, a steady stream of accused suppliers who need to knock the claim out.

The subject-matter has shifted with the industry. Alongside classic engine, transmission, chassis and body-in-white patents, the Turin docket now turns on electrification — battery packs, thermal management, power electronics and charging — and on driver-assistance, connectivity and human-machine-interface inventions. These are exactly the fields where a component maker or a rival OEM, sued in Turin over a widely implemented feature, has to show that the asserted claim was already old at its priority date.

For an accused automotive supplier the invalidity search has to reach beyond the patent literature. Much of the decisive art in this sector sits in engineering standards, SAE and ISO papers, supplier technical bulletins, trade-show disclosures, and older vehicle and component documentation that never surfaced during examination. A prior art search Turin defendants can build a nullity case on is one that mines that grey-literature and dates every reference to the day, so the CTU and the court see a disclosure the patentee’s examiner never did.

Aerospace and space: Turin’s second patent frontier

Turin is also one of Europe’s leading aerospace and space hubs, and it generates a second, very different body of patent disputes. Avio Aero, a GE Aerospace company, designs and builds aero-engine components at Rivalta di Torino; Thales Alenia Space engineers spacecraft and pressurised modules here, having supplied a large share of the pressurised volume on the International Space Station; and Leonardo anchors the region’s defence and aeronautics base. The Aerospace City project taking shape in Turin is drawing these players, research centres and the Politecnico di Torino into a single cluster.

The patents that get asserted in this world are dense and highly technical — turbine and combustion architectures, additive-manufacturing methods, advanced alloys and composites, satellite payloads, avionics and thermal-protection systems. Many of them are granted as European patents and, unless opted out, are exactly the assertions that can now be litigated at the UPC. Section A aside, aerospace subject-matter frequently falls into the mechanical and chemistry classes routed to the Munich and Paris central seats, so scoping matters as much as searching.

Invalidity work in aerospace leans heavily on non-patent literature: conference proceedings, defence and space-agency technical reports, academic theses from the Politecnico and its peers, and materials-science journals. Public availability and exact dating are frequently the hardest-fought issues, because the strongest reference is often a conference paper or technical report whose publication date decides whether it is prior art at all. That evidentiary discipline is the core of how we build an aerospace invalidity case for a Turin forum.

Italian nullity actions: the Article 76 grounds

In Italy a patent is revoked through a nullità (nullity) action, and the grounds are codified in Article 76 of the Italian Industrial Property Code (the Codice della Proprietà Industriale, Legislative Decree No. 30 of 2005). Any party with a legitimate interest can bring a standalone nullity action, and an accused infringer can also raise invalidity as a counterclaim inside the infringement suit — which, because the Italian court does not bifurcate, is decided in the same proceeding.

The grounds track the classic patentability requirements. A patent is null where the invention lacks the requirements of patentability — novelty, inventive step, industrial applicability or lawfulness; where the specification does not describe the invention clearly and completely enough for a skilled person to carry it out; where the subject-matter extends beyond the application as filed or protection has been impermissibly extended; or where the proprietor was not entitled to the patent. Italian case law treats this list as exhaustive.

• Lack of novelty — a single earlier disclosure that anticipates every element of the claim
• Lack of inventive step — the claim is obvious over the prior art, often a combination of references
• Insufficiency — the specification does not enable a skilled person to work the invention
• Added matter — the granted claims reach beyond the application as originally filed
• Lack of entitlement — the proprietor was not the person entitled to the patent

Novelty and inventive step are the grounds that turn on prior art, and they are where an invalidity search earns its keep. Because the court-appointed CTU weighs the references technically, the quality of the art — how closely it maps to the claim elements and how firmly its date is proven — often decides the case before the parties reach final argument.

EPO opposition: the nine-month central attack

Most of the valuable patents asserted in Turin arrive as European patents granted by the EPO and validated in Italy, and that opens a route the Italian courts cannot match. Within nine months of grant, anyone can file an opposition at the European Patent Office. A successful opposition revokes the patent centrally — in every state where it was validated, Italy included — in one proceeding, on the same novelty, inventive-step, added-matter and sufficiency grounds an Italian court applies.

The trade-off is timing. The nine-month window closes hard, and once it has passed an accused party is left with national nullity before the Tribunale di Torino or a revocation action at the UPC in Milan. Where the window is still open, EPO opposition and a national or UPC attack are not rivals but partners: one rigorous, claim-charted prior art search can feed an opposition, an Italian nullity action and a UPC revocation at once, so the same references do double or triple duty.

That is why we treat the grant date of any European patent asserted in Turin as a hard diary entry from the moment we are instructed, and scope opposition-grade art to the standard a national nullity action or a UPC revocation would demand. Getting the search done inside the window preserves every forum at once.

How PerspireIP builds a Turin invalidity search

Every engagement follows the same disciplined path. We map the asserted claims element by element, fix the priority date that actually governs each one, and search against that date rather than the filing date printed on the cover. For automotive and aerospace assertions we run patent searching alongside deep non-patent retrieval — engineering standards, SAE, ISO and space-agency technical reports, conference proceedings, supplier documentation, theses and archived product literature — and we date every reference to the day so its status as prior art cannot be disputed.

• Claim charting mapped to novelty and inventive step under Article 76 of the Italian Industrial Property Code and the EPC
• Deep non-patent retrieval across engineering, standards, aerospace and academic sources, in multiple languages
• Public-availability dating for every reference, evidenced for journals, conference papers and online disclosures alike
• Prior art scoped to your forum — a Tribunale di Torino nullity action, a UPC revocation in Milan, or the nine-month EPO opposition window
• A written invalidity analysis and reference packages ready for the court-appointed CTU, the UPC panel or the EPO

We work alongside your Italian and European counsel as a specialist search partner, deliver to Impresa-court, UPC and EPO deadlines, and keep every engagement confidential. Whether you are an automotive supplier facing an OEM’s assertion, an aerospace or defence contractor challenging a competitor’s patent, or litigation counsel preparing a nullity defence, we scale to fit — a single search, a multi-patent campaign or ongoing portfolio support. Send us the patent number and your key dates, and we will scope a prior art search Turin project within one business day.
