This edition addresses internal competence under Art. 33.1(b) UPCA, the territorial preconditions for unitary effect, the limits of enforcing UPC decisions beyond UPC territory, and the consequences of limiting a Unitary Patent while pursuing infringement claims concerning non-UPC states.
Local Division Paris (UPC_CFI_1963/2025, Order of 17 February 2026)
In Valeo v Bosch, the Paris Local Division rejected a preliminary objection under Rule 19 RoP and clarified the meaning of “same alleged infringement” in Art. 33.1(b) UPCA. Several Bosch entities had argued that the Paris Local Division lacked internal competence because different defendants were allegedly involved in different product variants and distribution channels, such that the action did not concern the “same alleged infringement”. The Court rejected that interpretation as adding an unwritten requirement to the provision. It held that the decisive point is that all defendants are alleged to infringe the same patent; Art. 33.1(b) does not require identity of accused products, identical commercial roles, or identical territorial conduct. Different embodiments, different positions in the supply chain, and the fact that not every defendant is implicated in relation to every product do not preclude application of the provision.

Court of Appeal (UPC_CoA_8/2026, Decision of 9 February 2026)
In Papst Licensing v EPO, the Court of Appeal dismissed an appeal against the rejection of a request for unitary effect for EP 3 327 608 and clarified an important eligibility requirement for unitary patents. The patent originated from a Euro-PCT application filed in 2005, when Malta had not yet joined the EPC and therefore could not be designated. By the time of grant in 2025, however, Malta had become both a participating Member State in the unitary patent system and a UPCA contracting state. Because the granted patent did not cover Malta, the EPO refused registration of unitary effect. The Court of Appeal confirmed that this refusal followed directly from Art. 3(1) of Regulation 1257/2012, which requires a European patent to be granted with the same set of claims in respect of all participating Member States.

Local Division Mannheim (UPC_CFI_365/2023, Order of 30 January 2026)
The Court drew a clear distinction between the UPC’s jurisdiction to decide on foreign infringement and the separate question whether such decisions can be coercively enforced abroad. Within UPC territory, UPC decisions are immediately enforceable. Outside the UPC system, however, coercive enforcement of UPC orders – particularly penalties for non-compliance with an injunction concerning foreign territory – requires prior recognition by the courts of the state concerned, unless an applicable recognition regime provides otherwise. At the same time, the Court accepted that disclosure obligations may still extend to foreign sales where that information is needed to quantify damages for infringing acts committed within UPC territory.

Local Division Paris (UPC_CFI_702/2024; UPC_CFI_369/2025, Decision of 16 January 2026)
In IMC Créations v Mul-T-Lock France, the Paris Local Division dealt with infringement of a European patent with unitary effect together with additional national validations, including Switzerland. The patent had been unconditionally limited during the UPC proceedings. The Court held that the limitation of the Unitary Patent took effect retroactively from the date of grant, with the result that the limited claim set governed the infringement analysis within UPC territory for the entire period since grant. For the Swiss national part, however, it drew a strict distinction: infringement had to be assessed on the patent as granted, because the limitation affected only the Unitary Patent and did not alter the Swiss validation. The Court nevertheless declined to rule on Swiss infringement. It reasoned that the proprietor’s decision to limit the Unitary Patent created a non-negligible risk that the broader granted Swiss claims would be revoked by the competent Swiss authorities, while the UPC itself had no jurisdiction to decide validity for the Swiss part. Although it indicated that, in principle, a serious validity risk for a non-UPC designation could justify staying infringement proceedings pending a decision by the courts of the relevant state, no revocation action was pending in Switzerland. In those circumstances, the Court did not stay the Swiss part but dismissed it outright.

January’s decisions and orders further refine the UPC’s practice. The Paris Local Division addressed urgency, added matter and the evidentiary threshold for software infringement at PI stage. The Munich Local Division clarified the limits of “possible infringing use” for medical devices and dealt with the cost consequences of conditional counterclaims. The Paris Central Division issued detailed guidance on how auxiliary requests must be drafted under Rule 30 RoP. Finally, the Düsseldorf Local Division demonstrated a pragmatic approach to stalled service abroad in PI proceedings against a China-based seller.
Paris Local Division (UPC_CFI_808/2025, Order of 23 January 2026)
In Guardant Health v Sophia Genetics, the Paris Local Division refused provisional measures concerning three liquid biopsy and bioinformatics patents. The Court dealt, first, with urgency under Rule 211.4 RoP and held that a three-month preparation period may be acceptable in a technically complex multi-patent case. It distinguished between general market awareness and sufficiently specific technical knowledge enabling a substantiated infringement analysis, accepting as the relevant starting point the date on which the applicant first had concrete product information allowing a meaningful technical assessment. On validity, the Court found that two patents were more likely than not invalid for added matter, rejecting any “reservoir” approach that seeks to assemble claim combinations from scattered passages without a clear pointer in the parent disclosure. It considered multiple unprompted selections from lists – such as selecting specific cancers and a particular gene-panel structure – as strongly indicative of added matter. As to the third patent, the application failed on infringement: the Court held that press releases and high-level marketing materials were insufficient to establish software-based infringement with the “sufficient degree of certainty” required by Rule 211.2 RoP, stressing the need for deeper technical insight into how the accused platform actually processes data.

Munich Local Division (UPC_CFI_628/2024; UPC_CFI_125/2025, Decision of 13 January 2026)
In Emboline v AorticLab, the Munich Local Division dismissed an infringement action relating to an embolic protection device. The dispute turned on whether the accused device implemented a “graspable structure … engageable by a hook” for retrieval within a catheter. While the Court reaffirmed that infringement is not necessarily excluded merely because a product is typically used in a non-infringing way, it introduced an important limitation for medical devices: a merely hypothetical claim-compliant use does not suffice where the alleged implementation would arise only in an abnormal, unsafe, or non-standard emergency scenario. The Court also dealt with a revocation counterclaim that the defendant converted at the oral hearing into a request conditional upon a finding of infringement. It treated this change as a limitation within the meaning of Rule 263.3 RoP and held that conditional counterclaims are not excluded as a matter of principle. However, because infringement was denied, the condition did not occur and no validity decision could be rendered under Art. 76.1 UPCA. The Court nevertheless ordered the counterclaimant to bear the costs generated by the counterclaim under Art. 69.3 UPCA, treating them as unnecessary costs caused by the defendant’s procedural structuring; overall, given the mirrored values, each party bore its own costs.

Paris Central Division (UPC_CFI_433/2024, Decision of 7 January 2026)
In Microsoft v Suinno Mobile & AI Technologies Licensing, the Paris seat of the Central Division revoked EP 2 671 173 in its entirety and provided extensive guidance on the admissibility and presentation of auxiliary requests under Rule 30 RoP. The Court distinguished between objective admissibility requirements – such as compliance with the Rule 30 deadline, inclusion of at least one amendment, and formulation in the language of the patent – and discretionary requirements relating to intelligibility, adequate explanation (including on Art. 84 EPC and Art. 123(2)/(3) EPC), and whether requests are reasonable in number. The Court’s central message was that amendments must be immediately intelligible without the Court reconstructing what the proprietor “must have meant”, consistent with the front-loaded structure of the RoP and the practical need for register-ready claim sets. It held that mere deletion may not require a consolidated document, but substantive amendments generally require filing a complete amended claim set within the Rule 30 deadline.

Düsseldorf Local Division (UPC_CFI_515/2025, Order of 19 December 2025; follow-up to 17 October 2025)
In Hewlett-Packard Development Company v Shenzhen Moan Technology, the Düsseldorf Local Division issued a follow-up order completing the provisional-measures package against a China-based defendant selling printer cartridges via Amazon. With service in China stalled, the Court relied on “good service” under Rule 275.2 RoP, deeming the steps taken to bring the application to the defendant’s attention sufficient and treating service as effective as of the date set in its earlier order. The Court proceeded by way of a regular PI order notwithstanding the defendant’s non-participation, rejecting the notion that a non-participating defendant should trigger default-judgment mechanics under Rule 355 RoP and emphasising that the PI regime under Rules 205 et seq. RoP follows its own structure. On urgency (Rule 211.4 RoP), the Court accepted HP’s tight evidence-gathering timeline—rapid test purchases, laboratory testing, and compilation of the infringement record—finding no unreasonable delay where the application was filed promptly once the evidentiary record was complete. The Court also declined to order enforcement security under Rule 211.5 RoP, exercising discretion in light of the defendant’s lack of engagement and the absence of apparent grounds necessitating a bond.

This month’s edition highlights significant developments across multiple UPC divisions, including key rulings on added matter, language of proceedings, proportionality of remedies, and the evolving approach to inventive step further departing from the EPO’s problem‑solution framework.
Local Division Munich – GXD-Bio v Myriad
19 December 2025 – UPC_CFI_437/2024; UPC_CFI_681/2024
The Munich Local Division revoked EP 3 346 403 in its entirety for added matter and, independently thereof, dismissed the infringement action. The Court held that the disclosure of breast cancer samples in experimental data did not amount to a disclosure of an invention limited to breast cancer. Nor was the exclusive use of OAZ1 as a sole reference gene directly and unambiguously disclosed. All auxiliary requests failed for the same reasons. Infringement was also denied because the attacked embodiment normalised gene expression to an average of multiple reference genes rather than to OAZ1 alone.

Court of Appeal – UERAN Technology v Xiaomi
19 December 2025 – UPC_CoA_902/2025
The Court of Appeal dismissed an appeal against an order of the President of the Court of First Instance changing the language of proceedings from German to English under Art. 49.5 UPCA. The Court confirmed the broad discretion of the President and emphasised that the assessment is based on fairness, taking into account all circumstances of the parties. If the balance is neutral, the defendant’s position prevails. Neither the seat of the Local Division nor the availability of machine translation is decisive. Appellate review is limited.

Local Division Düsseldorf – M-A-S v Altech
10 December 2025 – UPC_CFI_316/2024; UPC_CFI_547/2024
The Düsseldorf Local Division clarified important limits on remedies and pleading standards. In cases of indirect infringement, recall, removal and destruction will generally be disproportionate. Interim damages under Rule 119 RoP require a plausible, fact-based estimate; abstract lump sums were rejected. The Court further held that merely naming prior-art documents is insufficient for an inventive-step attack, which must be reasoned in substance. A revocation counterclaim against a third party was held procedurally admissible, but failed on the merits.
>> to the decision
Court of Appeal – Barco v Yealink
28 November 2025 – UPC_CoA_317/2025; UPC_CoA_376/2025
The Court of Appeal confirmed that Art. 33 UPCA governs only the internal allocation of competence within the UPC and is independent of Brussels I Recast. There is no hierarchy between competence based on the place of infringement and the defendant’s domicile, and no need for defendant-specific connecting factors at the competence stage. The Court also upheld the dismissal of provisional measures for lack of urgency, holding that an unreasonable delay occurred between knowledge of the alleged infringement and filing.

Court of Appeal – Meril v Edwards
25 November 2025 – UPC_CoA_464/2024 et al.
In Meril v Edwards, the Court of Appeal articulated a holistic approach to inventive step, explicitly departing from the EPO’s problem-solution approach. The Court first defined the objective problem based on the technical teaching of the patent and only then identified “realistic starting points” in the prior art. Obviousness was assessed by asking whether the skilled person would have taken the next step, not merely whether they could. The Court clarified that inventive step may also lie in a non-obvious alternative, even without technical improvement.

Court of Appeal – Amgen v Sanofi/Regeneron
25 November 2025 – UPC_CoA_528/2024; UPC_CoA_529/2024
In a parallel decision, the Court of Appeal confirmed the same holistic inventive-step framework and further elaborated the role of reasonable expectation of success. The likelihood of success, predictability of outcomes, and technical uncertainties were assessed globally, taking into account the maturity of the field and the strength of any pointer in the prior art. The decision reinforces the UPC’s clear divergence from the EPO’s problem-solution-approach.

This edition covers important rulings from the Court of Appeal, the Central Division Milan, and the Local Division in The Hague. Key themes include the rejection of claim construction, equivalence and limits regarding the number of validity attacks inrevocation proceedings.
The Hague Local Division (UPC_CFI_187/2024; UPC_CFI_507/2024, Decision of 18 November 2025)
In Advanced Cell Diagnostics v Molecular Instruments, the Hague Local Division ruled on two patents concerning RNA probe technologies. While both patents survived validity challenges, the panel found no infringement – neither literal nor by equivalence. It interpreted “non-overlapping” probe sequences as requiring an absolute absence of overlap and rejected the UK High Court’s more lenient approach in related litigation. The court also found that the accused overlap in MI’s HCR probes served a distinct technical function and could not be treated as an equivalent workaround. On novelty, the panel rejected a combination of Collins and Kern, holding that a generic reference to a second document was insufficient to constitute a direct and unambiguous incorporation for novelty purposes.

Court of Appeal (UPC_CoA_579/2025; APL_30654/2025, Decision of
7 November 2025)
The Court of Appeal overturned a preliminary injunction granted by the Hamburg LD in OTEC v STEROS and clarified that experimental data not disclosed in the patent specification are generally not relevant to claim interpretation. The ruling concerned an electrolytic polishing medium, where the decisive term was a “non-conductive fluid”. The court held that emulsions must be assessed as a whole and fixed the threshold for “not significantly conducting” at ≤ 10 µS/cm. Post-filed test data submitted by STEROS were disregarded, as were conductivity measurements that did not reflect the finished product as claimed.

Court of Appeal (UPC_CoA_762/2024; UPC_CoA_773/2024, Decision of 5 November 2025)
In Seoul Viosys v expert klein, the Court of Appeal confirmed the revocation of EP 3 223 320 for added matter. The decision contains important clarifications on how translations of international applications are treated for the purpose of Art. 123(2) EPC. The court held that where the original PCT application is not in an EPO official language, the applicant’s translation filed on Euro-PCT entry is presumed to be accurate and is binding unless the proprietor can prove otherwise. It also confirmed that “comprising” and the singular “a mesa” are not restrictive and, in the absence of clear limitations, cover multiple elements.

Central Division Milan (UPC_CFI_497/2024; UPC_CFI_571/2024, Decision of 23 October 2025)
In bioMérieux v Labrador Diagnostics, the Milan Central Division confirmed the validity of EP 3 756 767 B1 and upheld the patent in the form of Auxiliary Request 3. The panel criticised the claimant’s attempt to raise more than 50 separate invalidity attacks, calling it incompatible with judicial resources and indicative of poor strategy. It limited the claimant to a few selected prior art documents under Rules 262 and 263 RoP. The court declined to apply the EPO’s problem–solution approach and instead used a broad obviousness assessment based on whether the skilled person would have a motivation to combine known systems.

This month’s UPC decisions span critical developments in claim construction, inventive step, remedies, director liability, and jurisdictional authority. Notably, the Central Division Paris distances itself from the EPO’s problem-solution approach, while the Court of Appeal clarifies the UPC’s institutional legitimacy and solidifies pan-European enforcement tools under Art. 64 UPCA.
Central Division Paris (UPC_CFI_189/2024 & UPC_CFI_434/2024, Decision of 20 October 2025) – Holistic Inventive Step and Tailored Injunction in Valve Litigation
In Meril v. Edwards, the Paris Central Division ruled on EP 4 151 181 B1 (heart valves), notably rejecting the EPO’s feature-by-feature problem-solution approach in favour of a holistic inventive-step examination. The Court emphasised that the invention must be considered as a whole and criticised hindsight-biased formulations of the objective technical problem. The Court also upheld 17 auxiliary requests as admissible, confirming that complexity and multiple attacks justify their number. On added matter, the Court found an intermediate generalisation (removal of “heart” from “heart valve”) to violate Art. 76(1) EPC. Importantly, the injunction granted under Art. 63 UPCA was narrowed: XL-sized valves were exempted to preserve treatment options for certain patients, recognising a legitimate public-health interest. The Court rejected routing such exemptions through the patentee’s “Medical Request Portal”, holding that access must remain independent of competitor consent.

Local Division Düsseldorf (UPC_CFI_115/2024 & UPC_CFI_377/2024, Decision of 15 October 2025) – “Same Invention” and Material Selection in Line with EPO
In Hartmann Packaging v. Omni-Pac, the Düsseldorf Local Division addressed priority entitlement under Art. 87 EPC and inventive step in material selection. It reaffirmed that a valid priority claim requires direct and unambiguous disclosure of the claimed subject-matter, consistent with Art. 123(2) EPC standards. On inventive step, the Court held that selecting a material from a limited, known group of options – here, pulp compositions for moulded packaging – did not involve an inventive step.

Court of Appeal (UPC_CoA_288/2025, UPC_CoA_290/2025 & UPC_CoA_291/2025, Decision of 6 October 2025) – Milan Validly Replaces London; Rule 19.1 RoP Is Exhaustive
In Roku v. Dolby and Sun Patent Trust, Roku had challenged the UPC’s international jurisdiction and the legality of Milan replacing London as branch of the Central Division. The Court held that Milan’s designation by the Administrative Committee was valid under Art. 87.2 UPCA by analogy. The UPC’s framework was confirmed to be fully compatible with EU law, including Arts. 19 TEU and 267 TFEU. Additionally, the CoA confirmed that appeal fees apply per appeal, even for substantively identical cases.

Court of Appeal (UPC_CoA_534/2024 & UPC_CoA_683/2024, Decision of 3 October 2025) – “Offering”, Director Liability, and Art. 64 UPCA Remedies
In Philips v. Belkin, the CoA clarified the scope of “offering” under Art. 25 UPCA, confirming it has an autonomous economic meaning: even non-binding product presentations (e.g., via local-language websites) may amount to infringing offers. The Court upheld injunctions and damages against Belkin’s corporate entities but reversed the injunctions against managing directors, stressing that director liability requires intentional or knowing misconduct – mere management is insufficient. Importantly, the CoA reinstated recall, removal, and destruction as default remedies under Art. 64 UPCA, subject only to disproportionality defences. Requests for electronic disclosure must be timely; new forms of relief raised only on appeal will be inadmissible.

This month’s decisions and orders include a trade-fair inspection order, strict diligence under Rule 263 RoP (case amendments), clarifications on direct infringement by component supply, and the non-extendability of deadlines for unitary effect requests.
Local Division Düsseldorf (UPC_CFI_885/2025, Order of 22 September 2025) – Ex Parte Inspection Granted at EMO Trade Fair
The Düsseldorf Local Division authorised an ex parte inspection and evidence preservation under Art. 60 UPCA and Rules 192 et seq. RoP. The Court found a plausible case for infringement of EP 2 983 864 B1 by the PRO500 polishing unit exhibited at EMO Hannover 2025. The inspection order permitted a court-appointed expert, assisted by a bailiff, to operate the machine, record data, and if needed, seize one unit. The Court emphasised urgency and evanescence of evidence, rejecting a “test buy” as impractical. The expert’s report is initially confidential; OTEC will only receive it after redaction of any trade secrets. No security was ordered, as the inspection posed limited risk.

Court of Appeal (UPC_CoA_807/2025, Decision of 2 September 2025) – Strict Diligence Required for Amending Revocation Case (Rule 263 RoP)
In CeraCon v. Sunstar, the Court of Appeal dismissed an attempt to introduce a new novelty attack based on EP 3 868 480 months after the original revocation counterclaim. The Mannheim Local Division had denied the amendment, and the CoA affirmed, holding that Rule 263.2 RoP imposes a high bar: parties must show that the amendment could not have been made earlier with reasonable diligence. Here, the new prior art had been easily found with the same search strategy earlier. The CoA found no manifest error in the LD’s refusal and declined to override the panel’s discretion. This ruling reinforces the UPC’s front-loaded character and its intolerance of tactical delay in prior art submissions.

Local Division Mannheim (UPC_CFI_425/2024, Decision of 16 September 2025) – Infringement by Supply of Components only
In a dispute between GESTRA AG and Babcock Wanson regarding EP 3 057 932 B1, the Mannheim Division addressed whether infringement may arise when allegedly infringing components (valve body, actuator, adapter) are supplied in combination but not yet assembled. The Court confirmed infringement under Art. 25 UPCA (direct infringement), finding that the delivery of the parts in functional coordination sufficed, even if final assembly occurred only after delivery. The Court found no exhaustion under Art. 29 UPCA, as there was no authorised first sale. It also reaffirmed that technical function and interdependence of the parts was sufficient to show that they were “specially adapted means” under Art. 26 UPCA. The decision provides welcome clarity on infringement in modular or component-based delivery scenarios.
>> to the decision
Court of Appeal (UPC_CoA_601/2025, Decision of 12 September 2025) – Strict Deadline for Unitary Effect Requests Confirmed
The Court of Appeal confirmed the decision of the Central Divisoin (reported in our August edition) and dismissed a challenge against the EPO’s rejection of a late-filed request for unitary effect, filed more than one month after publication of the grant. The patentee invoked IT problems and confusion about the deadline but failed to demonstrate a procedural error or exceptional justification. The CoA held that the one-month deadline under Rule 6(1) UPR is strict and cannot be extended by analogy to Rule 134 EPC or by discretionary review under the UPCA. The decision further confirms the UPC’s deferential approach to EPO decisions on unitary effect and leaves no room for post-deadline rescue attempts, reinforcing legal certainty in the post-grant phase.
>> to the decision
This month’s decisions further clarify key aspects of UPC litigation, including indirect infringement, claim construction, service formalities, and cost allocation in revocation proceedings. The rulings from the Local Divisions in Munich and Düsseldorf and the Central Division Branches in Milan and Paris offer important guidance for both procedural and substantive strategy.
Local Division Munich (UPC_CFI_248/2024, Decision of 22 August 2025) – BRITA v. AQUASHIELD: Claim Construction, Exhaustion, and Indirect Infringement
In a landmark ruling, the Munich Local Division upheld EP 2 301 873 B1 in amended form and found infringement by AQUASHIELD. The Court clarified that a purpose-limited feature – a filter being suitable to interact with a “control valve” – does not require that function to be performed, only that the structure allows for it. The Court dismissed novelty objections and confirmed that exhaustion does not apply to inventive parts that are replaced beyond mere maintenance. On indirect infringement, the Court granted a limited remedy: rather than broad injunctive relief under Art. 64 UPCA, it imposed a duty to warn customers and required contractual undertakings from the infringer to prevent further use. The patent was upheld on Auxiliary Request 16.

Local Division Düsseldorf (UPC_CFI_346/2024, Decision of 22 July 2025) – Service at a Trade Fair Booth Is Valid
The Düsseldorf Local Division confirmed that personal service at an international trade fair booth (here: the defendant’s stand in Cologne) constitutes valid service under Rule 271 RoP. The Court reasoned that the booth personnel were acting as commercial agents capable of receiving legal documents. After no defence was filed, the Court granted a default judgment under Rule 355 RoP, including a permanent injunction, recall, and costs. The ruling has broad implications for international defendants who participate in trade fairs within the UPC territory – it confirms that such presence may suffice for initiating and continuing legal proceedings under UPC service rules.

Central Division Milan (UPC_CFI_612/2024, Decision of 26 July 2025) – Unitary Effect Refusal by EPO Upheld by UPC
The Milan seat of the Central Division dismissed a request to annul the EPO’s rejection of a request for unitary effect filed too late under Art. 9(1)(g) Regulation (EU) 1257/2012. The patentee argued that ambiguous EPO communications and technical issues had led to the delay. The Court disagreed, finding that the one-month deadline is strict and must be adhered to. It confirmed that the EPO’s administrative rejection did not involve a procedural defect under Rule 97 RoP and that the UPC has no discretion to reopen or review such rejections on equitable grounds. Note: With order of 16 September 2025, the Court of Appeal confirmed.

Central Division Paris (UPC_CFI_239/2024, Decision of 28 July 2025) – Narrowing Amendment Saves Patent; Costs Split 70/30
In revocation proceedings against EP 2 875 923 B1, the patentee Essetre Holding filed an immediate, unconditional main request limiting the claim to a machine with a single working surface shared between two frames. The Court construed the phrase “a working surface” to mean “one” surface, supported by the description’s emphasis on eliminating dual-table setups. This narrowed claim overcame the prior art, and the revocation action was dismissed insofar. However, the Court held that the challenger was partially successful – since the granted patent would likely not have survived – and awarded 70% of costs against the challenger, 30% against the patentee. The decision confirms that even proactive narrowing by the patentee cannot shield them from cost consequences.

June and July saw key decisions from the Court of Appeal and the Mannheim Local Division on representative qualifications, rehearing thresholds, territorial scope of UPC jurisdiction post-BSH, and confidential information access.
Court of Appeal (APL_32076/2025; UPC_CoA_614/2025, Order of 24 July 2025) – No Extensions Beyond Rule 12.1 Transitional Period for EPLC Eligibility
In a decisive order, the President of the Court of Appeal rejected a European Patent Attorney’s petition to be entered on the list of UPC representatives based on a non-accredited Italian course completed prior to 2020. The request was filed after the one-year transitional period under Rule 12.1(a) of the EPLC Rules, which expired on 3 June 2024. The Court held that this transitional pathway was time-limited and could not be revived by equity, legal certainty, or IT-related difficulties. Outside the window, only accredited EPLC certificates (Rule 2) or legal diplomas (Rule 11) confer eligibility. Arguments analogising to re-establishment under Rule 320 RoP were also dismissed. The ruling confirms that transitional access to the UPC list closed definitively and will not be reopened under equitable considerations or procedural leniency.

Mannheim Local Division (UPC_CFI_359/2023, Decision of 18 July 2025) – UPC Jurisdiction over UK Infringement Confirmed Post-BSH
The Mannheim Local Division applied the CJEU’s guidance in BSH Hausgeräte to confirm jurisdiction over UK-territorial infringement of EP 3 476 616. The defendant, Kodak, is EU-domiciled, and the court found that Art. 71b Brussels Ia – interpreted in light of BSH – permits the UPC to adjudicate UK acts on an inter partes basis. However, the court reiterated that it lacks power to issue erga omnes UK validity rulings or amend the UK register. Kodak’s defensive invalidity plea succeeded, with the court finding the UK claims obvious in light of previously submitted prior art. FUJIFILM’s auxiliary requests failed for lack of clarity and procedural compliance. The ruling underscores that while the UPC can assess UK infringement and validity defensively, formal relief affecting non-UPCA validations must remain territorially limited.

Court of Appeal (UPC_CoA_405/2024, Decision of 19 June 2025) – High Threshold for Rehearing; Familiarity with EPO Case Law Expected
The Court of Appeal rejected Alexion’s application for rehearing under Art. 81(1)(b) UPCA, following dismissal of its prior appeal against a refusal of provisional measures. The Court found no “fundamental procedural defect”, reaffirming that this extraordinary remedy requires a defect so severe it undermines the legitimacy of the process. Disagreement with the Court’s claim interpretation or evidentiary assessment does not suffice. Importantly, the CoA confirmed that representatives before the UPC must be familiar with relevant EPO jurisprudence – especially decisions from the Boards of Appeal and the Enlarged Board. These, while not binding, form part of the applicable legal context and must be anticipated and addressed in party submissions. The decision reinforces the UPC’s expectations regarding representative competence and procedural awareness.

Court of Appeal (UPC_CoA_221/2025, 222/2025, 223/2025, Order of 3 July 2025) – Strict Limits on Confidentiality Access Under Rule 262A
In a standard-essential patent (SEP) dispute between NST and Qualcomm, the Court of Appeal upheld the Munich Local Division’s decision to permit only one US-based attorney access to Qualcomm’s confidential documents. NST had requested access for multiple members of its US litigation team, arguing their deep involvement and technical expertise. The Court found that Rule 262A must be narrowly interpreted and that access must be strictly necessary. It declined to admit further US counsel, particularly as a technical expert with access was already in place and NST failed to identify specific, additional need. Qualcomm’s cross-appeal seeking to exclude even Mr. Stringfield was also rejected. The ruling highlights the UPC’s commitment to confidentiality protections, especially where documents may have strategic value in parallel US litigation.

This month, the UPC and the EPO Enlarged Board addressed important questions on jurisdiction, selective revocation, claim construction, and procedural fairness. From pre-June 2023 acts to fee payment timing, these decisions further consolidate the UPC’s interpretive autonomy while fostering convergence with EPO practice.
Central Division Paris (UPC_CFI_198/2024, Decision of 28 May 2025) – Selective Revocation Permissible; EP Revoked for Germany Only
In a revocation action brought by Aylo Premium against DISH concerning EP 3 822 805 B1, the Central Division Paris confirmed that a claimant may limit the territorial scope of revocation to selected Contracting Member States. Relying on Art. 76(1) UPCA and the ne ultra petita principle, the Court found no procedural bar to revoking only the German part of the patent. Art. 34 UPCA governs the effect of decisions, not the relief parties may request. Despite a pending EPO opposition hearing, the UPC proceeded, citing its one-year timetable and procedural maturity. The patent was ultimately revoked for added matter under Art. 123(2) EPC: the term “highest quality streamlet” was found to generalise beyond the disclosure of step-wise bitrate upgrades in the application. The ruling affirms both the UPC’s jurisdictional flexibility and its strict stance on intermediate generalisations.

Court of Appeal (UPC_CoA_156/2025, Order of 2 June 2025) – UPC Jurisdiction Confirmed over Pre-UPCA Acts and Opt-Out Gap
In a widely anticipated decision, the Court of Appeal confirmed the UPC’s jurisdiction over infringement acts predating 1 June 2023 and over acts committed during a prior opt-out. The appeal stemmed from an action filed by Esko-Graphics against XSYS relating to EP 3 742 231. XSYS had argued that the UPC lacked competence due to the timing of the alleged acts and a previously effective opt-out. The Court, however, found that jurisdiction under Art. 32 UPCA depends on the filing date of the action, not the timing of the infringing acts. A withdrawal of the opt-out re-subjects the patent to UPC jurisdiction in full, with no carve-out for interim periods. The CoA invoked international treaty principles (Vienna Convention) and the harmonisation goals of the UPCA. While the Court reserved judgment on whether substantive UPCA law applies to pre-2023 acts, its findings on competence provide welcome clarity for litigants navigating the transition period.

EPO Enlarged Board of Appeal (G 1/24, Decision of 18 June 2025) – Description Must Always Inform Claim Construction
In a landmark ruling, the Enlarged Board of Appeal of the EPO abandoned the “only-if-unclear” approach to claim construction, holding that claims must always be interpreted in light of the description and drawings – regardless of linguistic ambiguity. The decision brings EPO practice into alignment with the UPC Court of Appeal’s NanoString order (UPC_CoA_335/2023) and the inventive step analysis recently adopted by the Munich Local Division. The Board expressly cited the UPC’s jurisprudence as persuasive, emphasising the need for consistency across Europe. G 1/24 reaffirms that Art. 84 EPC and Art. 69 EPC (and its Protocol) are complementary: clarity is assessed at the drafting stage, but for patentability, the entire disclosure must be considered.

Court of Appeal (UPC_CoA_286/2025, Order of 23 June 2025) – Timely Fee Payment Requires Transfer Instruction, Not Receipt
In this order, the Court of Appeal addressed whether the court fee must be received or merely instructed at the time of filing. Referring to Art. 70(2) UPCA and Rule 371.1 RoP, the Court ruled that it is sufficient for the party to have given the order to transfer the fee at the time of lodging the pleading. Actual receipt may occur later. The Court reasoned that parties should not be penalised for banking delays, particularly in cross-border proceedings. It also rejected reliance on internal CMS metadata (such as PDF lodging timestamps) for determining timeliness. This clarification provides much-needed legal certainty for practitioners handling filings across multiple jurisdictions within the UPC.

This month’s decisions and orders highlight key developments in added matter, inventive step, second medical use claims, procedural timing for validity attacks, and preliminary injunctions with EU-wide reach. The UPC continues to refine its procedural and substantive standards.
Local Division Paris (UPC_CFI_163/2024, Decision of 23 May 2025) – Intermediate Generalisations and Territorial Scope under Art. 34 UPCA
In a decision dated 23 May 2025 concerning EP 3 155 936 B1 (juice squeezing module), the Paris Local Division allowed Hurom’s unconditional request to amend the claims but ultimately revoked the amended patent for lack of inventive step. The Court rejected objections under Art. 123(2) EPC, holding that the allegedly omitted features were not inextricably linked to the claimed subject-matter. It found the amended claims directly and unambiguously derivable from the application as filed. However, inventive step was denied over a combination of two prior art documents (CN202365584U and KR20130016748A). The Paris panel also clarified that objections under Art. 34 UPCA relate to the territorial effect of UPC decisions – not to jurisdiction – and may be raised outside the preliminary objection stage under Rule 19 RoP. The infringement claim concerning Poland failed for lack of factual substantiation, and the patent was revoked in all designated UPCA states.
Local Division Düsseldorf (UPC_CFI_505/2024, Decision of 13 May 2025) – Pleading Ignorance Rejected and No Infringement of Second Medical Use Claim
On 13 May 2025, the Düsseldorf Local Division dismissed an infringement action concerning EP 3 536 712 B1, a divisional claiming a second medical use of PCSK9 inhibitors for reducing Lp(a). The Court ruled that the evidence submitted did not establish that Repatha® was used for the claimed therapeutic indication. The decision is notable procedurally for its strong rejection of general denials or “pleading ignorance”, a practice permitted under § 138(4) ZPO in German civil litigation. The UPC held that under Rule 171.2 RoP, facts not specifically contested are deemed admitted and that evasive denials are insufficient. Substantively, the Court confirmed the claim’s validity under Art. 54(5) EPC and held that scientific uncertainty around Lp(a) metabolism justified an inventive step.
Local Division Düsseldorf (Procedural Order of 8 May 2025) – New Prior Art or New Lines of Attack in Revocation Replies Require Justification
In a procedural order issued on 8 May 2025, the Düsseldorf Local Division clarified the requirements for introducing new prior art or new arguments in reply to a revocation counterclaim under Rule 263 RoP. The Court held that such replies represent an amendment of the case and are only admissible if the defendant demonstrates due diligence and absence of procedural prejudice to the claimant. Even new attacks based on already-cited prior art must meet this threshold if introduced for the first time at the reply stage.
Court of Appeal (UPC_CoA_768/2024, Order of 30 April 2025) – Court Grants Cross-Border Preliminary Injunction and Clarifies Claim Construction
On 30 April 2025, the Court of Appeal overturned the Milan Central Division’s refusal and issued a preliminary injunction covering 17 UPCA member states (excluding Romania) in favour of Insulet Corporation against EOFlow. The dispute concerned patch pump devices and EP 4 201 327. The CoA clarified that claim construction is a question of law for the Court, not experts, and found that the prior art did not disclose the specific clutch mechanism required by the claim. Inventive step was confirmed, and infringement was deemed likely. The absence of a cease-and-desist declaration justified the assumption of risk of continuation. The Court granted broad relief, including pan-European injunctive relief, disclosure obligations under Art. 67 UPCA, penalty payments, and full cost reimbursement. The case confirms that the UPC may grant sweeping provisional measures even beyond countries where the patentee actively markets its product.
