Not manufacturable, but state of the art
Departing from the approach established in G 1/92 for assessing whether a publicly available product is state of the art, the Enlarged Board of Appeal holds in ist decision G 1/23 that the requirement of reproducibility is met if a product is commercially available. Public availability alone suffices, irrespective of whether the skilled person is able to manufacture the product. This article analyses the legal reasoning of G 1/23 and ist implications for novelty and inventive step. Lessons are drawn for inventors seeking patent protection for newly developed products and their competitors relying on commercially available products as prior art.

G 1/24 has been one of the most eagerly awaited decisions in 2025, considering that a large number of different Technical Boards of Appeal at the EPO generated a bunch of diverging case law over decades when it came to the question whether the description and drawings of a patent must be considered for assessing the subject matter of the claims. With its decision G 1/24 (GRUR-RS 2025, 13433 – Heated Aerosol Generating Article; Hütt GRUR Patent 2025, 336), the Enlarged Board of Appeal aimed at ensuring a uniform application of the EPC and decided that the description and drawings are always referred to when interpreting the claims, and not just in the case of unclarity or ambiguity of the claims. As after every major decision the question arises whether everything has been clarified now. The short answer to this question is “No”. It is the subsequent case law after a landmark decision which refines, interprets and adapts the precedent to different technical contexts and legal scenarios. About half a year after decision G 1/24, the principles of this decision have already been put into practice by dozens of Technical Board of Appeal decisions. Thus, it is time for an interim assessment.

Artificial intelligence in patent law – revolution or evolution?
The use of artificial intelligence (AI) in patent attorney firms promises significant efficiency gains and quality improvements – from research and patent applications to opposition and infringement proceedings. This article provides a practice-oriented examination of concrete AI applications in patent attorney work, discussing the professional and economic benefits, the legal framework, and the technical limitations of AI language models. Finally, the question is discussed: Does AI represent an evolutionary development for the patent attorney profession or even a revolution?

The Editors’ Choice – UPC (CoA.), 3.10.2025 - Belkin/Philips
In its second ever appeal decision in main infringement actions, the Court of Appeal tackled, among other matters, a popular instrument of patent proprietors to exert pressure on infringers: the personal liability of company directors. The Court of Appeal held that it is not sufficient for a director to have general knowledge of the circumstances which lead to the infringement. Rather, a director must be aware of the unlawfulness of the act. This marks a departure from what practitioners know from certain national jurisdictions, where personal liability of directors is more easily established.

No “interpretative somersaults” at the EPO – another step towards a uniform European interpretation practice
A claim should not be interpreted, based on features set out in embodiments of an invention, as having a meaning narrower than the wording of the claim as understood by the person skilled in the art. In cases of discrepancy between the claim language and the description, it falls upon the patentee to remedy this incongruence by amending the claim. It is not the task of the Boards of Appeal to reach such alignment by way of interpretative somersaults.

The Unified Patent Court – a case law overview VII
2025 is coming to an end, and 2026 marks the start of the third year of the Unified Patent Court (“UPC”), which, with around 1,500 published decisions and orders, has established itself as one of the preferred courts for patent litigation. Applying the Rules of Procedure (“RoP”) and the UPC Agreement (“UPCA”), the UPC strives to find practical solutions to procedural and substantive legal challenges, making it of paramount importance for the development of new uniform patent law and harmonizing procedural law across Europe. It therefore continues to be useful to provide an overview in order to facilitate access to the Court's case law on the RoP and the UPCA.

The Editors‘ Choice – UPC (LD Düsseldorf), 10.4.2025
The decision of the LD Dusseldorf addresses several key issues: The focus is on the interpretation of product-by-process claims. The court also examines jurisdiction over actions that took place before June 1, 2023, and prior to an opt-out and determines that the UPCA applies also to ongoing acts that began before its entry into force while national law applies to compensation claims arising from the patent application. Lastly, the LD comments on the commencement of the limitation period.

Regional Court Munich I – Anti-Interim License Injunction (AILI)
On 26 September 2025, the Regional Court Munich I, 21st Civil Chamber issued a landmark decision in the InterDigital/Amazon video licensing dispute: It handed down the first ever Anti-Interim License Injunction (“AILI”). The injunction was issued ex parte. Apparently, there was the concern that hearing the defendant could lead to ex parte counter-measures from the UK torpedoing the Munich case. Only four days later, the UPC Local Division Mannheim issued a similar AILI (docket number UPC CFI 936/2025, GRUR-RS 2025, 31129). Amazon requested in both cases a re-hearing. The Mannheim rehearing took place on 14 November 2025, but the decision has not yet been handed down. In Munich, the rehearing took place on 26 November 2025, and the judgment was handed down same day. The AILI was confirmed, and the court made remarkably distinct statements on international private law and jurisdiction for license rate determination.

Territorial scope of decisions on the infringement of European bundle patents under Article 34 UPCA
According to Art. 34 UPCA, in the case of a European patent, the decisions of the UPC cover the territory of those contracting member states for which the European patent has effect. This article examines the question of whether it is sufficient for this cross-border effect to be proven in only one country of protection that there is an imminent or actual infringement. A decision of the Local Division of Mannheim dated March 11, 2025 raises doubts about this.

The Editors' Choice – UPC (LD Hamburg), August 14, 2025 – UPC CFI 387/2025, GRUR-RS 2025, 25175
The Hamburg Local Division confirms the broad international jurisdiction claimed by the UPC. It specifies the conditions for the inclusion of defendants based outside the EU and cross border injunctions. Therefore, the LD specifies the scope of application of Art. 8 (1 Regulation (EU) No 1215/2012 (“BR”) and the conditions under which a company can be considered an intermediary according to Art. 63 (1) 2nd sentence UPCA. It is a clear signal that the UPC is willing to grant far-reaching injunctions.

The Editors’ Choice – UPC CoA 228/2025, GRUR-RS 2025, 26146 – Roku International/Sun Patent Trust
The defendants had disputed the jurisdiction of the UPC with arguments under EU law and, in the alternative, requested a referral to the ECJ. They had also objected to the replacement of London by Milan as a division of the Central Division as incompatible with the UPCA and had derived from this an argument of the lawful judge at the UPC Local Division seized. The latter and the court of appeal rejected both arguments and rejected the application for a referral.

Aggregate Royalty for Cellular SEPs in Recent Court Decisions
Standards organizations developing cellular communication standards typically require participants to disclose standard essential patents (SEPs) and agree to license such patents on fair, reasonable, and non-discriminatory (FRAND) terms. When courts are asked to adjudicate license disputes involving SEPs, they often calculate the implied aggregate royalty for all SEPs in the relevant standard associated with a potential license. We review five recently litigated FRAND cases and report the aggregate royalties for the 4G and 5G cellular standards that can be derived from these cases. We find that the aggregate royalty per mobile device in most of these decisions falls in a range from $3 to $16, with an average of $9.25. The aggregate royalty by the UK Court of Appeal in Optis/Apple is an outlier at $39.47.
(Nadia Soboleva and John Hayes, GRUR Patent 2025, page 546)
The first two and a half years of UPC Court of Appeal (CoA) jurisprudence on substantive patent law and patent validity are characterised by cautious initial guidance and selective alignment with the established practice of the European Patent Office (EPO). While the Court largely follows EPO principles, especially regarding the assessment of novelty and disclosure, it refrains from explicit references to EPO case law and maintains a reserved approach to formulating guiding principles. A notable exception is the assessment of inventive step, where the Court neither adopts the EPO’s formal problem-solution approach nor defines its own method. This strategy preserves the UPC’s judicial independence and flexibility for future divergence but also delays early legal certainty for users. For practitioners, EPO case law remains a practical reference, although the potential for deviation must always be considered.

European bundle patents at the UPC and national courts - applicable infringement law
The law that the Unified Patent Court and national courts are to apply to infringements of European patents is highly controversial. This article attempts to take stock of the discussion and to present the authors’ position on this issue. It also discusses the differences between the UPCA and German infringement law.

The Editors’ Choice – UPC CoA 380/2025, GRUR-RS 2025, 21002 – expert/Viosys
The case concerns the relationship of the international law foundations of the UPCA and their intertwinement with Union law. In the context of a dispute over cost reimbursement, the Court of Appeal had the opportunity to make concise but fundamental statements, attempting to strike a balance between the UPCA’s autonomy under international law and the respect for the primacy of Union law.

On the future of patent jurisdiction in Germany and Europe: parallelism instead of competition!
For the past two years, the European patent litigation landscape has been changing with the creation of the Unified Patent Court (UPC), which now operates alongside national courts. After the initial excitement, it’s time to take a step back and consider how the two systems might develop in the long run. This was the focus of the 17th Mannheim IP Forum, organized by Prof. Dr. Lea Tochtermann and the Interdisciplinary Center for Intellectual Property (IZG e.V.) at the University of Mannheim on July 11, 2025. Much of the current discussion focusses on competition between the different court systems. In the future however, a more integrated structure of the systems could emerge, offering choices such as whether to seek national, European, or unitary protection—or even a combination of them. The conference aimed to explore differences and similarities between the systems and offer a perspective on what the next years might hold.

The eagerly awaited opinion of the Enlarged Board of Appeal of the EPO in case G 1/24 “Heated aerosol” (GRUR-RS 2025, 13433) is now available. The Enlarged Board of Appeal leaves open the legal basis for the interpretation of the claims. At the same time, it emphasizes that the description and drawings in the patent specification must always be used for interpretation. The Board of Appeal rejects the view that the description and drawings should only be consulted in cases of ambiguity or uncertainty regarding the claims. It gives the following succinct and accurate reasoning: The finding that a claim is clear and unambiguous is already the result of an interpretation of that claim and cannot precede it. This pointed statement by the Enlarged Board of Appeal gives reason to examine in detail why legal texts such as laws and patent claims must always be interpreted.

Life sciences at the UPC – highly effective right from the start!
When the UPC was launched, there was considerable speculation about how active the life sciences sector would be represented. It is now clear that decisions/orders from life sciences proceedings (also) shape the UPC – and given the outstanding economic importance of this sector, this is to be welcomed!
(Oliver Jan Jüngst and Moritz Schroeder, GRUR Patent 2025, page 494)
Rarely has there been such a major upheaval in European civil law as is currently the case in patent law. At the forefront of this legal revolution is the implementation and adoption of the Unified Patent system over the past two years, including patent litigation under a completely new set of procedural rules before the Unified Patent Court. As a further not yet implemented component of this transformation, Art. 35 UPCA provides for the establishment of a Patent Mediation and Arbitration Centre (“PMAC”). This center is expected to become fully operational in early 2026. Public consultations regarding its mediation and arbitration rules have recently taken place. In the first article of this three-part series, the authors provided an overview of arbitration’s past and present state. The second part examined the specific challenges that may arise when arbitrating patent disputes. This third part will focus on how the PMAC’s draft arbitration rules reflect these findings.

The Editors’ Choice – UPC (LD Mannheim), 11 March 2025 – UPC CFI 162/2024, GRUR-RS 2025, 3769
The decision discussed below primarily addresses, on the one hand, the relationship between Art. 26 Brussels Ia Regulation and R. 19.7 RoP UPC, clarifying the precedence of Art. 26 Brussels Ia Regulation. On the other hand, the court examines which substantive law applies to acts of infringement depending on the date of the entry into force of the UPCA. Accordingly, the substantive law of the UPCA applies to acts committed after its entry into force or to ongoing acts extending beyond that date, whereas national law applies to earlier acts completed before that point in time.
