Infringement Analysis in Delft.

A patent infringement analysis Delft companies can act on has one rare advantage: the court that will decide the case sits barely ten kilometres up the road. Delft, the historic canal city in South Holland between The Hague and Rotterdam, is home to TU Delft — one of Europe’s leading engineering universities — and to a dense cluster of robotics, high-tech engineering, photonics and cleantech spin-outs. When one of those inventions is copied, the dispute is heard by the specialist patent judges of the District Court of The Hague, the only court in the country that hears patent cases. PerspireIP builds the element-by-element claim charts and evidence-of-use that prove — or defeat — that an accused product practises the claim, scoped to the Dutch national court or the Unified Patent Court where the matter will actually be decided.

Where a patent infringement analysis Delft case is heard

The Netherlands runs its patent litigation through a single, highly specialised forum. The District Court of The Hague (Rechtbank Den Haag) holds exclusive nationwide jurisdiction over patent-infringement and validity disputes, and appeals go exclusively to the Hague Court of Appeal (Gerechtshof Den Haag). Both courts run a dedicated patent division staffed by experienced judges, several of them technically trained, who do little else. For a Delft rights-holder this is an unusually convenient geography: the plateau of TU Delft spin-outs sits roughly ten kilometres from a courthouse built specifically for technically dense patent cases — a bench that rewards a rigorous, limitation-by-limitation reading over rhetoric.

That concentration shapes how a case is argued. Because the same small group of judges hears every Dutch patent dispute, they are fluent in claim construction, prosecution history and the technical detail of the accused product, and they expect the file put in front of them to be equally disciplined. A conclusory “the product clearly infringes” assertion does not survive; a claim chart that maps each element of the asserted claim to a documented feature of the real product does. The Hague also reviews first-instance judgments in full on appeal, so the technical record built at trial carries straight through to the Court of Appeal.

• District Court of The Hague — the sole first-instance court for Dutch national patents, with a specialist patent division that hears every infringement and validity action in the country
• Hague Court of Appeal — the single appellate forum for Dutch patent judgments, reviewing the case in full
• Technically trained bench — a compact group of judges, some with engineering backgrounds, who read the claim chart element by element
• Proximity — a Delft dispute is litigated barely ten kilometres away, an unusually convenient home forum for the region’s inventors

The kort geding and the Dutch cross-border injunction tradition

The Netherlands is famous in patent circles for speed. Its kort geding — summary or preliminary-injunction proceedings before the District Court of The Hague — lets a patentee obtain a provisional decision within weeks rather than years, and, crucially, it is a standalone action: no full trial on the merits needs to be pending. For a Delft start-up watching a competitor launch a copy at a trade fair, a kort geding is an efficient, cost-effective way to force a fast injunction against ongoing or threatened infringement. The compressed timetable also raises the bar on the evidence: the whole case for infringement has to be ready and persuasive on day one.

The Dutch courts are also the historic home of the cross-border injunction. Since the Supreme Court’s 1989 Lincoln v Interlas ruling — that a defendant’s obligation to stop infringing need not halt at the national border — The Hague has repeatedly granted injunctions reaching beyond the Netherlands, in both summary proceedings and proceedings on the merits. That tradition makes the forum attractive for a patentee whose accused product ships across Europe, and it raises the stakes of the underlying technical read: a cross-border order is only as defensible as the claim chart that supports it.

• Kort geding — fast preliminary-injunction proceedings that deliver relief in weeks and do not require a pending action on the merits
• Standalone speed — the entire infringement case must be evidenced up front, which puts a premium on a complete claim chart
• Cross-border reach — a Dutch tradition, rooted in Lincoln v Interlas (1989), of injunctions that extend past the national border
• Proceedings on the merits — a fuller track for damages and a final injunction when the dispute cannot be resolved on the provisional read

The Unified Patent Court local division in The Hague

Since 1 June 2023 a second route runs in parallel with the national court. The Unified Patent Court (UPC) operates a local division in The Hague that hears infringement and revocation of European patents that have not been opted out, and of unitary patents. Proceedings can be conducted in Dutch or English, and the division’s registry operations are run in cooperation with the Netherlands Patent Office. A UPC judgment reaches across every participating member state at once, so a Delft patentee can choose a pan-European injunction over a purely Dutch one — a powerful option for hardware and software that sells across the single market.

The choice of track is a genuine strategic decision, and it turns on the underlying patent. A classic Dutch national patent, granted by Octrooicentrum Nederland without substantive examination, is enforced in the District Court of The Hague. A European patent may be litigated nationally, opted out of the UPC, or asserted before the UPC for pan-European effect. The technically qualified UPC panels expect the same discipline as the Dutch bench, with the added feature that a revocation counterclaim regularly travels alongside the infringement action. Whichever forum is chosen, the deciding question is identical: does the accused product fall within the claim?

• UPC local division, The Hague — hears infringement of non-opted-out European patents and unitary patents, in Dutch or English, live since 1 June 2023
• Pan-European injunction — a single UPC judgment covers every participating member state, an attractive option for cross-border products
• Opt-out choice — European patents can be kept in, or opted out of, the UPC, a decision that shapes the whole enforcement strategy
• Parallel revocation — a nullity or revocation counterclaim commonly runs with the infringement case, so the invalidity file must be built in step

Delft deep-tech: robotics, engineering and cleantech patents

Delft’s patent docket is written by its industry mix, and that mix is unusually deep-tech. TU Delft (Delft University of Technology) is one of Europe’s top engineering schools and a prolific spin-out engine; the YES!Delft incubator has seeded hundreds of high-tech start-ups, and the RoboHouse field lab and TU Delft’s robotics groups anchor a robotics cluster, with agri-robotics leaders such as Lely operating nearby. Layered on top are high-tech engineering and photonics, cleantech in hydrogen, solar and water technology — think the university’s Nuna solar-car heritage — and the QuTech quantum institute, whose spin-outs still sit within a few kilometres of campus.

Each of those sectors generates a different flavour of infringement question, and each demands a different kind of proof. A robotics patent typically blends mechatronics with control software, so the evidence has to reach both the physical mechanism and the algorithm that drives it. A high-tech engineering or precision-hardware patent turns on the device itself — a teardown, dimensional measurement and reverse-engineered CAD. A cleantech patent on an electrolyser, a solar cell architecture or a water-treatment module is proven from the built device, its materials and its measured performance. The common thread is that a datasheet is never enough; the analysis has to reach the physical or coded reality of the accused product.

• Robotics & mechatronics — TU Delft and RoboHouse spin-outs and agri-robotics neighbours, where control software and physical mechanism must both be charted
• High-tech engineering & photonics — precision hardware and optics proven by teardown, measurement and reverse-engineered CAD
• Cleantech — hydrogen, solar and water-technology devices proven from materials, structure and measured performance
• Quantum & deep-tech — QuTech-rooted hardware and control electronics, where the claimed invention lives in novel physics and instrumentation

Building the claim chart and evidence of use

The specialist Hague judges and the UPC’s technically qualified panels expect a disciplined evidentiary file, not assertion. Everything starts with claim construction fixed from the claims, the specification and the prosecution history, and then each element is mapped against the real accused product. The methodology is chosen to fit the technology: a hardware teardown with dimensional measurement and reverse-engineered CAD for engineering and cleantech devices; software behaviour, APIs, logs and, where available, source for the control layer of a robotics system; and materials or performance testing for an electrolyser or a photonic component.

• Element-by-element claim charts mapping every limitation of the asserted claim to a documented, dated feature of the accused product
• Evidence-of-use from teardowns, dimensional measurement, reverse-engineered CAD, control-software analysis, protocol traces and materials or performance testing
• Robotics matters charted across both the mechatronic mechanism and the control algorithm, so the software and the hardware are each pinned to a limitation
• Non-infringement and design-around positions for an accused implementer, with claim construction anchored to the specification and file history
• A coordinated invalidity file, because a nullity or revocation counterclaim commonly runs alongside the infringement case in The Hague and at the UPC

The deliverable is scoped to the forum. A Dutch kort geding demands a complete, self-contained read that stands up on day one; a proceeding on the merits allows a fuller damages and infringement file; a UPC action follows its own front-loaded, fast timetable to trial. What never changes is the core of a patent infringement analysis Delft litigants can rely on: a claim chart an independent expert and a specialist judge can adopt, built on evidence rather than conclusions.

How PerspireIP builds a Delft infringement-analysis file

Every engagement follows the same path. We fix the correct claim construction from the claims, the specification and the prosecution history, then map each element against the real accused product using the right method for the technology — teardown, measurement and CAD for engineering and cleantech hardware, control-software and behavioural analysis for robotics, materials and performance testing for photonics and energy devices — charting infringement literally and, where appropriate, under the doctrine of equivalents.

• Claim construction and element-by-element charting against a Dutch national patent, a European patent or a unitary patent
• Evidence-of-use assembly — teardowns, CAD reconstruction, control-software analysis, protocol traces and materials or performance data — dated and documented for a Hague judge or a UPC panel
• Infringement and non-infringement positions built for either side, coordinated with any parallel nullity or revocation challenge
• Deliverables scoped to the track: a kort geding file, a merits complaint, or a UPC statement of claim built to its front-loaded timetable

We work alongside your Dutch and international counsel as a specialist analysis partner, deliver to District Court of The Hague and UPC deadlines, and keep every engagement confidential. Whether you are a TU Delft spin-out enforcing a robotics or cleantech portfolio, an accused implementer clearing a path to market, or litigation counsel preparing a claim or a defence, we scale to fit — a single claim chart, a multi-patent matter, or ongoing portfolio support. Send us the patent number and the accused product, and we will scope the work within one business day.
