How to Litigate Standard‑essential Patents (seps) in Italy 2026: FRAND Defences, Injunction Risk and Practical Steps

SEP litigation Italy is entering a decisive phase in 2026, as procedural reforms, cross‑border enforcement pressure and evolving FRAND jurisprudence reshape how standard‑essential patents are enforced and defended before Italian courts. Whether you are a rightsholder weighing an injunction or an implementer preparing a FRAND defence, the practical calculus now turns on evidence quality, timing and coordination with parallel proceedings before the Unified Patent Court and in Asia. This guide sets out a step‑by‑step playbook for pursuing or resisting SEP injunctions in Italy, with an evidence checklist, model procedural timeline, costs table and a comparison of injunction risk across Italy, the UPC and China.

It is written for in‑house counsel, licensing teams and outside counsel who must decide, this year, whether to enforce, license or litigate.

Overview: What SEP Litigation in Italy Involves

Standard‑essential patents in Italy are patents that a rightsholder has declared essential to a technical standard (typically through an ETSI declaration) and has undertaken to license on fair, reasonable and non‑discriminatory (FRAND) terms. Because implementers cannot make standard‑compliant products without practising those patents, the tension between the patent holder’s right to an injunction and the implementer’s right to a FRAND licence sits at the heart of every dispute. Italian courts approach this tension through the framework established by the Court of Justice of the European Union in Huawei v ZTE (Case C‑170/13), which conditions the availability of injunctive relief on both parties having engaged in a good‑faith licensing negotiation.

The remedies available, including preliminary and final injunctions, damages and recall, flow from the Italian Industrial Property Code (Legislative Decree No. 30/2005), while procedural mechanics are governed by the Code of Civil Procedure. Milan is the dominant forum for complex patent disputes, with a specialised business court section (sezione specializzata in materia di impresa) experienced in technical and economic evidence. In 2026, SEP litigation Italy cannot be planned in isolation: parallel actions before the UPC and in China frequently run alongside Italian proceedings, and coordination of forum, timing and evidence is now a strategic necessity rather than an afterthought.

When This Guide Applies

This guide applies where a declared SEP is being asserted or challenged in Italy, whether through a full infringement action, a request for interim relief, a declaratory FRAND action, or a defensive posture raising competition‑law arguments. It assumes a standard‑setting context (telecommunications, video codecs, connectivity) and a licensing dispute rather than a pure validity contest.

Quick Decision Checklist

• Confirm essentiality. Do you hold (or face) a genuinely essential claim, supported by a robust claim chart?
• Assess the FRAND record. Has a compliant offer and counter‑offer sequence been documented under Huawei v ZTE?
• Test injunction exposure. Is the implementer a willing licensee, or is there evidence of hold‑out?
• Map parallel proceedings. Are there live UPC or Chinese actions affecting forum strategy?
• Budget the experts. Have you provisioned for both essentiality and FRAND economic reports?

Eligibility: Who May Sue and Who May Raise a FRAND Defence

Standing and posture determine everything that follows. Before drafting a single pleading, both sides should confirm who holds enforceable rights, who is properly an implementer, and whether the FRAND defence is genuinely available on the facts.

Who Is a Rightsholder?

A rightsholder is the proprietor or exclusive licensee of a patent effective in Italy (via a European patent designating Italy, an Italian national patent, or a European patent with unitary effect covering Italy) that has been declared essential to a standard. Standing to seek an injunction generally requires clear title, a current entry in the patent register, and, where an exclusive licensee sues, evidence of the licence and any contractual authority to enforce. Portfolio owners asserting a family of SEPs should be prepared to demonstrate essentiality for each asserted claim, not merely the declared status of the family.

Who Is an Implementer?

An implementer is a party that manufactures, imports, offers or sells products that practise the standard in Italy. Distributors and importers can be defendants for enforcement and customs purposes, but the substantive FRAND negotiation typically runs with the manufacturer or the entity controlling licensing decisions.

When Is a FRAND Defence Available?

The FRAND defence is available where the asserted patent is genuinely standard‑essential and subject to a FRAND undertaking, and where the implementer has behaved as a willing licensee. Under Huawei v ZTE, an implementer who declines to engage, delays, or refuses to provide security for past use risks losing the shield and exposing itself to an injunction. The defence is not automatic, it must be earned through documented, timely conduct.

Step‑by‑Step SEP Litigation Italy: The Procedural Playbook

The following eight steps form the core procedural sequence for SEP litigation Italy, from pre‑litigation audit through post‑judgment enforcement. Each step identifies the lead actor, indicative timing, the evidence required and tactical guidance. Timings are estimates drawn from typical practice before the Milan specialised business court and will vary with court backlog and case complexity.

Step 1, Pre‑litigation Audit and Essentiality Check

Who: rightsholder or implementer. Duration: 2–6 weeks. Begin by confirming the substantive foundation of the case. For the rightsholder, this means preparing claim charts that map each asserted SEP claim to the relevant clause of the standard and to the accused product, collecting the ETSI or standard‑setting declarations, and commissioning an essentiality opinion. Select the asserted claims deliberately to minimise the attack surface: fewer, strongly essential and valid claims are more persuasive than a scattergun assertion of a whole family. For the implementer, the mirror exercise is a rebuttal essentiality analysis and a prior‑art scan to prepare validity challenges. This audit shapes forum choice, budget and settlement leverage before any pleading is drafted.

Step 2, FRAND Offer and Hold‑Out Risk Assessment

Who: both parties. Duration: 1–8 weeks, sometimes continuing. The Huawei v ZTE sequence begins here. The rightsholder should notify the implementer of the infringement, identifying the SEP and the manner of use, and then present a written FRAND offer specifying the royalty and the method of calculation. The implementer must respond diligently, and if it rejects the offer, present a written FRAND counter‑offer; if that counter‑offer is rejected, it must provide appropriate security for past use and account for its acts. Every communication, offer and rejection should be dated and retained, the negotiation record is often decisive on injunction risk.

Rightsholders should assess whether the implementer is genuinely negotiating or engaging in delay (hold‑out); implementers should be alert to premature injunction threats that pre‑empt genuine talks.

Step 3, Filing Suit: Forum, Claims and Provisional Measures

Who: rightsholder. Duration: filing in one day, service within roughly four weeks. Choose the competent court, usually the Milan specialised business court for complex SEP matters. The complaint should plead infringement of the identified SEP claims, attach the claim charts, and, where interim relief is sought, set out the grounds for a preliminary injunction, including urgency (periculum in mora) and a prima facie case (fumus boni iuris). Tactically, a rightsholder that has scrupulously followed the FRAND steps strengthens the case for interim relief; a rightsholder that has not risks the court declining an injunction on Huawei v ZTE grounds.

Consider whether to seek a preliminary injunction at the outset or to reserve it, depending on the strength of the FRAND record.

Step 4, Defendant Response: FRAND and Abuse‑of‑Dominance Defences

Who: implementer. Duration: 4–12 weeks. The implementer files its defence, which in FRAND cases typically combines: a formal demonstration of willing‑licensee conduct under Huawei v ZTE; a documented FRAND counter‑offer; a request that the court fix FRAND terms or award damages rather than an injunction; and, where appropriate, a competition‑law argument that seeking an injunction against a willing licensee amounts to an abuse of a dominant position. The implementer may also seek a stay pending parallel proceedings or a determination of FRAND terms. Validity and essentiality challenges are usually mounted here in parallel.

Step 5, Evidence and Expert Exchange

Who: both parties. Duration: 8–16 weeks. SEP disputes turn on two categories of expert evidence: technical experts addressing essentiality, infringement and interoperability; and economic experts addressing FRAND royalty benchmarking, comparable licences and valuation methodology. Italian courts frequently appoint a court‑expert (consulente tecnico d’ufficio) whose report carries significant weight, with the parties’ own experts (consulenti tecnici di parte) contributing. Prepare disclosure requests early, comparable licence agreements and negotiation records are often the most contested documents. The party with the more coherent, well‑evidenced economic model tends to control the FRAND narrative. Note that Italian civil procedure does not provide for broad common‑law‑style discovery; document production is more limited and generally requires a specific, targeted request to the court.

Step 6, Interim Injunction Hearing and Enforcement

Who: court and both parties. Duration: hearing typically within 4–12 weeks of filing. Where interim relief is sought, the court weighs the prima facie case, urgency, and, critically in SEP matters, the parties’ conduct against the Huawei v ZTE framework and the proportionality of an injunction. The court may require the rightsholder to post security, and may tailor the scope of any injunction. Public‑interest considerations, particularly where the standard underpins widely used products, may inform the balancing exercise. An injunction against a genuinely willing licensee is unlikely; an injunction against a demonstrable hold‑out is far more attainable.

Step 7, Trial, Remedies and Appeals

Who: both parties. Duration: typically 1–2 years or more to first‑instance judgment in complex matters. At trial the court resolves infringement, validity, essentiality and, where the injunction is contested, the FRAND terms and the appropriateness of injunctive versus monetary relief. Outcomes range from an injunction and recall to a damages award or a court‑framed FRAND determination. Many SEP disputes settle once the court‑expert’s report crystallises the technical and economic positions. Judgments may be appealed to the Corte d’Appello and, on points of law, to the Corte di Cassazione, each of which adds months to years to the timeline.

Step 8, Post‑Judgment Enforcement and Cross‑Border Coordination

Who: both parties. Duration: 1 year to several years. Enforcement of an Italian judgment may involve customs measures against infringing imports, execution against assets, and coordination with parallel actions. Where a rightsholder holds or seeks relief before the UPC or in China, the sequencing of enforcement matters: a UPC judgment may ease enforcement across participating member states, while enforcement into China requires separate local proceedings. Cross‑border coordination, aligning claims, avoiding inconsistent positions on FRAND rates, and managing anti‑suit and anti‑anti‑suit injunction risk, should be planned from Step 1, not improvised at judgment.

Tactical Evidence Tips

• Commission independent essentiality analysis. A third‑party opinion is often more persuasive than an in‑house view.
• Build the economic model early. Comparable licences and a defensible royalty methodology anchor the FRAND case.
• Preserve the negotiation record. Signed, dated offers and counter‑offers are the backbone of any Huawei v ZTE argument.

Sample FRAND Offer Checklist

• Identification of the specific SEP and the manner of infringement.
• The royalty rate and the calculation method behind it.
• The scope (portfolio, territory, field of use) and duration.
• Comparable licences or benchmarks relied upon.
• A reasonable response deadline and a record of transmission.

Required Documents and Evidence

Both plaintiffs and defendants should assemble a documentary record before proceedings begin. The table below sets out the recommended materials in SEP litigation Italy and who should typically produce each.

Timeline and Deadlines

Italian procedure imposes concrete windows that shape strategy. Understanding the cadence helps both sides plan resourcing and settlement timing.

• Filing to first defence. Statutory time limits are set by the Code of Civil Procedure and depend on the mode and date of service; the defendant must appear and file its defence within the terms fixed in the summons and by the applicable rules.
• Interim injunction motion. Often heard within 4–12 weeks of filing, subject to court backlog and the complexity of the FRAND record.
• Expert phase. The court‑expert phase and party expert reports commonly run several months.
• Trial on merits. Frequently 1–2 years or more to first‑instance judgment in complex SEP disputes.
• Appeals. Proceedings before the Corte d’Appello and, on points of law, the Corte di Cassazione add several months to years.

Where accelerated procedural avenues are available for intellectual property matters, they can compress the interim phase, but the substantive FRAND and essentiality analysis still demands time for expert evidence. Parties should treat the interim injunction window as a decisive strategic pressure point and prepare their FRAND record accordingly. The timing of counter‑offers and security under the Huawei v ZTE sequence carries outsized consequences: delay by the implementer can convert a strong FRAND defence into injunction exposure.

Costs and Fees

Litigating a SEP dispute in Italy is expensive, driven principally by expert evidence. The table below gives practical, indicative ranges; actual figures depend on the number of asserted claims, the scale of the economic analysis and whether interim relief and cross‑border enforcement are pursued. Court fees (the contributo unificato) are set by law and scale with the value and type of proceedings; confirm the current tariff with the court or counsel.

What Changes in 2026 for SEP Litigation Italy

Several developments converge in 2026 to alter how SEP litigation Italy is conducted. On the domestic side, ongoing civil‑justice reform continues to push toward tighter case management and, in some tracks, procedural acceleration, which in practice can mean shorter windows to assemble evidence and a heavier front‑loading burden on both parties. Courts increasingly expect rigorous, independently supported essentiality evidence rather than reliance on declared status alone, raising the bar for rightsholders who have historically leaned on portfolio breadth.

At EU level, the maturing jurisprudence of the Unified Patent Court is influencing strategy for Italian actions. As UPC divisions develop their own approach to SEP injunctions and FRAND, rightsholders and implementers must decide how national Italian actions interact with centralised UPC proceedings, including the timing of opt‑out decisions for European patents and the risk of inconsistent FRAND determinations across forums. Italy hosts a UPC local division in Milan, which has become a significant venue for patent disputes. Readers should also note that a separate EU regulation on SEPs proposed by the European Commission remains subject to the ordinary EU legislative process; parties should verify its status before relying on it.

The practical effect is a gradual convergence of evidentiary expectations, with well‑documented FRAND negotiation records and robust economic reports becoming standard in both venues.

The recommended tactical adjustments for 2026 are concrete. Rightsholders should prepare the full economic FRAND model earlier in the lifecycle, register and timestamp every offer, and select asserted claims with discipline. Implementers should engage promptly and demonstrably as willing licensees, provide security where required without undue delay, and prepare their counter‑offer economics before litigation begins. Both sides should map UPC and Chinese exposure at the outset, because the sequencing of parallel actions, and the management of anti‑suit injunction risk, increasingly influences the outcome. Parties who invest in evidence quality up front, rather than reacting to court deadlines, tend to hold the strategic advantage.

Common Pitfalls and How to Avoid Them

• Relying on weak essentiality opinions. Commission an independent third‑party essentiality audit rather than resting on the declaration alone.
• Poorly documented FRAND offers. Use a standardised template and retain signed, dated records of every offer and counter‑offer.
• Rushing to seek an injunction without FRAND engagement. Follow the Huawei v ZTE steps in sequence; a premature injunction request can undermine the whole action.
• Under‑budgeting expert evidence. Plan costs and adopt a phased expert strategy so the economic and technical reports are ready when needed.
• Ignoring cross‑border implications. Coordinate customs measures and parallel suits early to avoid inconsistent FRAND positions and anti‑suit exposure.

Injunction Risk Compared: Italy, the UPC and China

Forum choice in cross‑border SEP enforcement turns substantially on how each venue approaches injunctions and FRAND. The table below compares the principal factors at a general level; approaches continue to evolve and specific outcomes are fact‑dependent.

Conclusion

SEP litigation Italy in 2026 rewards preparation over improvisation. The venues, remedies and FRAND framework are settled enough to be planned, but the outcome turns on the quality of the essentiality analysis, the discipline of the FRAND negotiation record, and the coordination of parallel proceedings before the UPC and in China. Rightsholders who follow the Huawei v ZTE steps and build their economic model early preserve their route to an injunction; implementers who engage promptly and document willing‑licensee conduct preserve their defence.

For any party weighing whether to enforce, license or defend a standard‑essential patent in Italy this year, the practical message is to invest in evidence and cross‑border strategy at the outset, because in SEP litigation Italy, the decisive advantages are often won long before the interim hearing.
