SEP Litigation and FRAND Disputes in Romania (2026): Injunctions, Licensing Strategies and When to Litigate

SEP litigation Romania has become a live strategic question in 2026 as the Unified Patent Court (UPC) matures and reshapes how standard-essential patents are enforced across Europe. Holders of standard-essential patents and the implementers who use those technologies now face a genuine fork in the road: sue for an injunction, negotiate a FRAND licence, or run both tracks in parallel. This guide takes a clear position on when each route makes sense, grounded in the CJEU framework from Huawei v ZTE, Romanian procedural reality, and the cross-border reach of the UPC.

The recommendation, in short: litigate only from a position of documented essentiality and validity against a demonstrably unwilling licensee, otherwise negotiate, but always negotiate with a credible litigation timeline in hand.

Note that Romania is a Contracting Member State of the UPC Agreement, but the UPC’s territorial effect in Romania is subject to Romania’s completion of ratification and entry into force. Counsel should confirm the current status of Romania’s participation before relying on UPC injunctions taking effect in Romanian territory.

Quick answers, a short decision map for SEP litigation Romania

• Can you get an injunction? Yes. Romanian courts grant patent injunctions and provisional measures, and the UPC can grant injunctions with effect across participating member states. But injunctive relief against an SEP is conditioned on compliance with the FRAND negotiation duties set out in Huawei v ZTE.
• When to negotiate. When the implementer is willing, credible benchmark evidence exists, and you value predictable royalty revenue and market penetration over an exclusionary threat.
• When to litigate in the UPC. When you need cross-border injunctive scope, the implementer is stalling, and you can shoulder the antitrust exposure and expert-heavy evidentiary burden.
• The default posture. Prepare litigation, threaten credibly, and keep FRAND terms ready, the hybrid approach usually delivers the strongest settlement leverage. See the full decision framework below.

Can an SEP holder obtain an injunction? Romania courts vs UPC

Injunctive relief is the sharpest weapon in any SEP litigation Romania strategy, but it is also the most heavily conditioned. For standard essential patents in Romania and across the EU, the governing principle is the CJEU’s judgment in Huawei v ZTE: a dominant SEP holder that has committed to license on fair, reasonable and non-discriminatory terms cannot simply seek to prohibit an implementer without first following a structured negotiation protocol. The holder must notify the implementer of the infringement, make a written FRAND offer, and give the implementer a fair opportunity to respond. Where the holder skips these steps, seeking an injunction can itself constitute an abuse of dominance.

Both Romanian courts and the UPC apply this framework, so the threshold question in any injunction analysis is not merely “is the patent infringed? ” but “did the holder behave as a willing licensor?

Romanian courts, procedural route and standards

Romanian patent enforcement proceeds through the national civil courts, with the Bucharest Tribunal (Tribunalul București) handling much of the patent litigation caseload. A claimant must prove ownership, essentiality to the relevant standard, validity, and infringement. Provisional measures are available under Romanian procedural law and can move relatively quickly, allowing a holder to secure interim relief before a full trial concludes. Registration and status data underpinning ownership claims flow from the Romanian State Office for Inventions and Trademarks (OSIM). The evidentiary bar for essentiality and rate justification is high, and courts will expect detailed technical and economic material. Enforcement of a granted Romanian injunction is territorial, it stops infringing activity within Romania.

UPC, cross-border injunctive power and strategic effects

The UPC changes the calculus by offering injunctions that can extend across participating member states in a single action. For UPC SEP enforcement, the court’s decisions and case law database shows a developing body of practice on jurisdiction, provisional measures and injunctive scope. A UPC injunction can exclude an implementer from a substantial share of the European market at once, a far more powerful lever than a purely national order. That reach cuts both ways: the broader the injunction, the greater the disruption, and the greater the scrutiny of whether the SEP holder complied with FRAND duties before seeking to shut the implementer out.

Practical takeaways, timing and enforcement risk

Romanian provisional measures can be obtained faster than a full UPC merits decision, making national relief attractive where speed and a domestic market matter most. The UPC’s advantage is breadth. In every case, the enforcement risk is that an injunction is stayed or refused because the holder failed the Huawei v ZTE conduct test or because a proportionality or antitrust defence lands. Plan the negotiation record before you plan the injunction; the two are inseparable in modern SEP litigation Romania.

How FRAND licence terms and rates are determined, evidence and methodology

Whether you litigate or negotiate, the FRAND rate is the battleground. Determining a defensible FRAND licence royalty is an evidentiary exercise, and courts, Romanian and UPC alike, increasingly demand rigorous economic proof rather than assertion. The ETSI framework matters here: declared SEPs and the FRAND undertaking derive from the ETSI IPR policy, which sets the baseline expectation that declared essential patents will be licensed on fair, reasonable and non-discriminatory terms. That undertaking is the anchor for every rate argument. The non-discrimination limb, in particular, means a holder cannot offer materially different terms to similarly situated licensees without objective justification.

Key evidence to build your FRAND case

The strongest FRAND cases are built on comparable licences, real agreements the holder or others have concluded for the same or adjacent portfolios. Comparables often carry significant persuasive weight. Beyond comparables, a well-prepared party should assemble:

• Essentiality evidence. Claim charts mapping asserted patents to specific provisions of the standard, ideally supported by third-party essentiality checks.
• Portfolio scope. A clear account of how many truly essential patents the holder controls, to place any per-patent rate in context of the wider standard.
• Royalty base and rate structure. Whether the rate applies to the end device or a component, and the justification for the chosen base.
• Non-discrimination benchmarks. Records showing what similarly situated licensees pay, to defend against discriminatory-treatment challenges.
• Negotiation correspondence. The full paper trail demonstrating willing-licensor or willing-licensee conduct under Huawei v ZTE.

Expert economics: common methodologies and pitfalls

Economic experts typically triangulate a FRAND rate using comparable-licence analysis, top-down apportionment against an aggregate royalty burden for the standard, and, where relevant, factor-based reasoning analogous to the Georgia-Pacific approach familiar from other jurisdictions. Each has pitfalls. Comparables can be attacked as non-comparable in scope, term or bargaining context. Top-down analysis depends on contested assumptions about the total number of essential patents and the appropriate aggregate rate. A common failure is royalty-stacking blindness, pricing a single portfolio without regard to the cumulative burden of every SEP reading on the same standard, which can produce commercially impossible rates.

Distinguish carefully between retrospective rates (for past use) and prospective rates (going forward), and consider whether a component-level rate is appropriate where suppliers rather than device makers are the natural licensees.

Documentation and procedural tactics for FRAND disclosure

FRAND disputes are document-heavy and confidentiality-sensitive. Comparable licences are usually confidential, so parties must be ready to deploy protective orders and confidentiality clubs to place sensitive agreements before the court without wider disclosure. Sequence disclosure deliberately: a holder should be prepared to justify its offer with benchmarks, while an implementer should demand the technical and rate evidence needed to assess the offer before accepting or counter-offering. Poorly managed disclosure is a frequent cause of delay and of adverse conduct findings in SEP litigation Romania.

Implementer defences: FRAND offers, non-infringement, abuse of dominance and proportionality

Implementers are not passive targets. The Huawei v ZTE framework gives a well-advised implementer several routes to resist an injunction, provided it plays its own role as a willing licensee. An effective implementer defence strategy combines FRAND conduct arguments, competition law, and traditional patent challenges.

FRAND negotiation defence and “willing licensee” vs “willing licensor”

The central defence is to show that the holder failed its Huawei v ZTE obligations, that it sought an injunction without a proper notification, without a genuine FRAND offer, or without giving the implementer a fair chance to respond. To rely on this defence, the implementer must itself behave as a willing licensee: respond promptly, make a serious counter-offer, and, where required, provide security for past use. The willing-licensee posture is the price of admission for the FRAND defence; an implementer that stalls may forfeit it and hand the holder a cleaner path to injunctive relief.

Antitrust and abuse of dominance arguments in Romania and the EU

Seeking to injunct an implementer who is willing to take a FRAND licence can amount to an abuse of a dominant position under EU competition law (Article 102 TFEU), an area the European Commission has actively examined in the ICT sector. Domestically, the Romanian Competition Council (Consiliul Concurenței) enforces the national prohibition on abuse of dominance and can pursue exclusionary conduct. An implementer can plead abuse of dominance as a shield against an injunction and, in appropriate cases, pursue a stand-alone damages claim. The credibility of the antitrust argument rises sharply where the holder skipped the FRAND negotiation steps.

Non-infringement, invalidity and proportionality defence

Classic patent defences remain decisive. An implementer should test whether the asserted patents are genuinely essential and genuinely infringed, over-declaration of essentiality is common. Validity challenges, informed by European Patent Office case law and guidelines on claim interpretation and oppositions, can knock out the patents underpinning the injunction. Finally, proportionality is a distinct and growing consideration: even where infringement is made out, a court may weigh whether an injunction that stops an entire product line is proportionate to the value of one SEP among many reading on the standard.

Licensing strategy vs litigation, a dimension-by-dimension comparison

This is the centrepiece decision for any SEP litigation Romania program. The table below compares the two primary routes, enforcing through litigation to secure an injunction, versus negotiating a FRAND licence and avoiding injunctive proceedings, across the dimensions that actually drive outcomes. Read it as a positioning tool: it tells you which route tends to dominate on each axis so you can weight the axes that matter most to your commercial goal.

Decision framework, which route to choose

Choose “enforce / seek injunction” when:

• You hold strong essentiality and validity evidence and face a demonstrably unwilling licensee.
• Speed to stop sales in Romania, or across participating member states via the UPC, would protect market share or a supply chain.
• You can bear high litigation and antitrust risk and have the resources to fund technical and economic experts.
• The infringer is a direct competitor whose exclusion carries strategic value beyond the royalty itself.

Choose “negotiate / seek FRAND licence” when:

• You value continuous market access for the implementer and predictable royalty revenue over exclusion.
• The implementer demonstrates willingness to take a licence and credible benchmark evidence exists.
• You want to avoid antitrust scrutiny and the cost and uncertainty of cross-border litigation.
• Broad market penetration of the licensed technology serves your long-term commercial interest.

Choose the hybrid route, threaten but prepare to license, when:

• You can open negotiation with a credible litigation timeline and provisional measures ready to file, using the injunction threat as leverage while keeping compliant FRAND terms on the table.

Practical litigation tactics in Romania, pre-trial, provisional measures and experts

Winning SEP litigation Romania cases is as much about preparation and sequencing as about legal merit. The tactics below apply whether you ultimately go to trial or use litigation to force a settlement.

Seeking provisional measures and emergency relief

Provisional measures are the fastest lever in the Romanian toolkit. A holder seeking interim relief must present a persuasive case on infringement and validity while showing urgency and a risk of harm that would be difficult to remedy later. Because provisional measures can bite quickly, they are a powerful negotiation catalyst, but a holder that files them without a compliant FRAND record invites an abuse-of-dominance response. Implementers, conversely, should be ready to oppose provisional measures immediately, filing a serious FRAND counter-offer and marshalling non-infringement material to blunt the urgency argument. Ownership and status evidence should be confirmed against OSIM records before filing.

Choosing experts: technical vs economic

SEP cases require two distinct expert disciplines: technical experts to establish essentiality and infringement through claim mapping, and economic experts to justify or attack the FRAND rate. Engage both early. The credibility of your rate case rests on the economist’s ability to defend comparables and apportionment under cross-examination, while the technical expert must survive scrutiny on essentiality, the point where over-declared portfolios most often collapse.

Managing evidentiary disclosure and confidentiality

Comparable licences and rate models are commercially sensitive. Establish protective arrangements, confidentiality clubs and protective orders, before exchanging documents, and plan a disclosure sequence that reveals only what is necessary at each stage. Mishandled confidentiality can stall proceedings and damage relationships that a licence would otherwise preserve.

UPC strategic considerations for SEP litigation Romania

The UPC is a significant variable in 2026 enforcement planning. Deciding between the UPC and Romanian courts is a genuine forum choice with lasting consequences, and counsel should confirm the current territorial reach of the UPC as regards Romania before relying on it.

When the UPC is preferable to Romanian courts

The UPC is preferable when cross-border injunctive scope is the objective, a single action that can restrain infringement across multiple participating member states. It suits portfolio holders whose commercial harm is European rather than purely Romanian, and who want one coordinated proceeding rather than a patchwork of national suits. The UPC decisions database is the primary reference for its developing approach to SEP injunctions, provisional measures and jurisdiction. Where the market to be protected is chiefly Romanian, or where local facts and speed favour national relief, the Romanian courts remain the sharper instrument.

Opt-out, forum shopping and coordination with parallel proceedings

Forum strategy must account for the opt-out mechanism for classic European patents and for the risk and opportunity of parallel proceedings. A holder may run national and UPC actions on different patents to spread risk and multiply pressure; an implementer may seek to concentrate disputes in a single, more favourable forum. Coordination is essential, inconsistent positions across forums are exploited by the other side. Map every asserted patent’s status, its opt-out position, and the interaction between any Romanian and UPC action before filing anything.

Post-judgment enforcement and customs

Securing an injunction is only half the battle; enforcing it is the other half. In Romania, a granted injunction is enforced through the national execution framework, and non-compliance can trigger further coercive measures. For products crossing borders, customs enforcement is a practical complement: EU customs procedures under Regulation (EU) No 608/2013 allow rights holders to apply for infringing goods to be detained at the border, potentially stopping infringing imports into Romania and the wider single market before they reach customers. Customs action is particularly valuable where the infringer sits outside the jurisdiction and physical goods are the vector of infringement.

The main enforcement challenges are identifying consignments accurately, keeping essentiality and validity findings current, and coordinating customs detention with the underlying court order so that the two reinforce rather than undermine each other.

Checklist for counsel: pre-suit and in-suit tasks

The following checklist consolidates the tactical steps either side should complete when preparing for SEP litigation Romania or a FRAND negotiation:

1. Essentiality audit. Map each asserted patent to specific standard provisions and stress-test declared essentiality.
2. Validity review. Assess exposure to invalidity and opposition, drawing on EPO case law and guidelines.
3. FRAND offer drafting. Prepare a compliant, benchmarked written offer that satisfies the Huawei v ZTE sequence.
4. Comparables assembly. Collect and analyse comparable licences and confirm non-discrimination positioning.
5. Provisional measures package. For holders, ready an interim-relief filing; for implementers, prepare rapid opposition and a serious counter-offer.
6. Antitrust defence prep. Evaluate abuse-of-dominance exposure or defences under EU and Romanian competition law.
7. Forum decision. Decide Romania vs UPC, checking opt-out status, the current territorial reach of the UPC, and parallel-proceeding risk.
8. Confidentiality regime. Establish protective orders and confidentiality clubs before any exchange of sensitive material.
9. Enforcement plan. Line up execution steps and customs detention in advance of any judgment.

Conclusion and recommended next steps

SEP litigation Romania in 2026 rewards preparation and punishes improvisation. The defensible position is clear: build the essentiality, validity and FRAND record first, then decide the forum. Litigate, in Romania for domestic speed or the UPC for European reach, only when you hold strong evidence against an unwilling counterparty and can absorb the antitrust and cost exposure. Otherwise negotiate a FRAND licence, but always with a credible litigation timeline behind it.
