Patent Drawing in The Hague.

No other city in Europe concentrates this much intellectual-property machinery inside a few kilometres. Octrooicentrum Nederland, the Dutch patent office, sits at Prinses Beatrixlaan 2 in The Hague, and the District Court of The Hague holds exclusive first-instance jurisdiction over every Dutch patent dispute. That concentration is why patent drawing The Hague work has to satisfy several different sets of form requirements at once, and why a figure set built only to US standards will be rejected on arrival. This page sets out what the Dutch rules actually demand, which filing routes remain open, and the drawing traps that cost Hague applicants the most.

Why patent drawing The Hague work answers to four institutions at once

Most city pages about drawings have one office to describe. The Hague has four bodies that can each reject or reinterpret your figures, and they do not apply the same rules. The Benelux Office for Intellectual Property, which registers every Benelux design and trademark, is at Bordewijklaan 15 in the same city, the European Patent Office’s largest Netherlands site is immediately south in Rijswijk, and a UPC local division sits alongside the Dutch court. Scoping patent drawing The Hague work therefore starts with deciding which of them your figures actually have to satisfy.

Octrooicentrum Nederland (OCNL), part of the Netherlands Enterprise Agency under the Ministry of Economic Affairs, grants Dutch national patents and publishes the formal requirements your sheets must meet. The European Patent Office’s The Hague branch, at Patentlaan 2 in Rijswijk, is the EPO’s biggest investment in its history in the Netherlands, with working space for around 1,950 staff in premises inaugurated in 2018. It matters to a Dutch applicant for a reason most people miss: OCNL does not produce its own search reports, so the search on your Dutch national application is prepared by the EPO under a cooperation arrangement. The examiner reading your figures is very likely sitting in Rijswijk.

The Benelux Office for Intellectual Property (BOIP) handles designs and trademarks, because the Dutch patent office registers neither. And the District Court of The Hague is where the figures are finally construed, under Article 80 of the Rijksoctrooiwet 1995.

A figure set prepared for one of these and filed at another is the most common avoidable failure in Dutch practice. The requirements overlap but do not coincide, so the working method is to build one master set that clears all of them rather than adapting late.

The Dutch sheet: A4, one dark colour, and margins that are not the US margins

OCNL publishes its form requirements for Dutch patent documents directly, and they are specific. Drawings must be on A4, 21 by 29.7 cm, used on one side only, on paper that is flexible, strong, white, smooth, non-glossy and durable, and that arrives uncreased, untorn and unfolded.

The margins are where US-trained teams come unstuck. The Dutch requirement is a top margin of 2 cm, a left margin of 2.5 cm, a right margin of 2 cm and a bottom margin of 2 cm. Compare that with 37 CFR 1.84(g) in the United States, which requires 2.5 cm top, 2.5 cm left, 1.5 cm right and 1.0 cm bottom. Neither specification contains the other. A sheet built to US margins fails the Dutch right and bottom minimums; a sheet built to Dutch margins fails the US top minimum.

The fix is simple once you see it, and it is the single most useful thing on this page: build to 2.5 cm top, 2.5 cm left, 2 cm right and 2 cm bottom. That envelope satisfies both regimes simultaneously, so one master sheet travels in either direction without redrawing.

Three further Dutch constraints are absolute:

• One dark colour only. OCNL requires strong, evenly drawn lines in a single dark colour. Colour drawings are not accepted, and unlike the United States there is no petition route to get them in. Where 37 CFR 1.84(a)(2) lets a US utility applicant petition for colour with the fee under 37 CFR 1.17(h), the Dutch answer is simply no.
• No photographs. Again with no petition mechanism behind it.
• Figures clearly separated and numbered consecutively across the whole set, not restarted per sheet.

The text-matter rule that CAD exports break every week

This is the trap that generates the most formalities correspondence for Hague applicants, and it is almost always an artefact of the software rather than a drafting decision.

Dutch practice limits the words allowed inside a drawing to a short list: indications such as water, steam, the cross-section marker “II-II”, open and closed, plus the designations genuinely needed to make an electrical block diagram or a manufacturing flow diagram intelligible. Everything else has to come out.

Then there is the requirement that catches people who thought they had complied: any text matter that does remain must be in the same language as the description. File a Dutch-language description with English labels still sitting in the figures and the set is inconsistent on its face.

In practice the offenders are rarely deliberate labels. They are CAD title blocks, drawing-number stamps, revision tables, layer names printed in the plot, scale bars, company watermarks and the software’s own footer. A clean-looking PDF export from a mechanical CAD package routinely carries three or four of these. Stripping them is part of preparing the figures, not an afterthought, and it is work a drafter has to do deliberately because the exporting engineer cannot see the problem.

A registration patent means the formalities exam is the only exam

The Netherlands grants what is called a registration patent, and understanding this changes how much the drawings matter.

OCNL does not examine novelty or inventive step. A search report is prepared, by the EPO under the cooperation arrangement described above, and published with the application. The patent is then granted regardless of what that search report found. The term is twenty years from the filing date.

The consequence is a genuine inversion of the usual risk model. In a substantively examined system, a weak drawing tends to surface during prosecution, because an examiner arguing about scope reads the figures closely and raises objections you can answer. In the Dutch system there is no such conversation. The formalities examination is the only examination the application receives, so it is also the only point at which anyone from the office looks hard at your figures before grant.

Under Article 76 of the Rijksoctrooiwet 1995 an interested party can ask OCNL for a non-binding advisory opinion on validity or scope. That is typically the first occasion on which the file is read rigorously, and by then the file is closed and the patent is granted. A figure that fails to show a claimed feature is therefore a defect you discover in a dispute, not in prosecution. Dutch registration patents reward drawing discipline more than examined systems do, not less.

Only two routes into the Netherlands, because the PCT national route is closed

A good deal of published advice on Dutch filing is simply out of date on this point, so it is worth being blunt. There are two routes to patent protection in the Netherlands, not three.

1. A direct Dutch national filing at OCNL, including via the Paris Convention priority route within twelve months of a first filing elsewhere.
2. A European patent at the EPO, designating the Netherlands and then validated after grant.

The PCT national route is closed. WIPO’s PCT Applicant’s Guide states flatly for the Netherlands that the Office closed the national route, so there is no national-phase entry at OCNL from an international application. A PCT applicant who wants Dutch coverage reaches it through the regional European phase at the EPO instead. Reform proposals under the Nieuwe Rijksoctrooiwet would reopen the national route, but that is not law, and planning a filing programme on it would be a mistake.

This has a direct drawing consequence. Because Dutch coverage from an international application runs through the EPO, your figures need to satisfy current European presentation standards rather than Dutch national ones for that pathway, and PCT Rule 11 for the international phase that precedes it. Two of the three regimes a Hague applicant deals with are therefore not the Dutch regime at all.

One more structural rule: Article 77 of the Rijksoctrooiwet 1995 prohibits double protection, so you cannot hold a Dutch national patent and a validated European patent covering the same invention in the Netherlands. Choose the route deliberately.

Validating a European patent, and the three-month Dutch claim trap

Where the route is a European patent, Dutch effect depends on a post-grant step with a hard deadline. The claims must be translated into Dutch and filed within three months of grant, together with a fee of EUR 25, or the European patent has no effect in the Netherlands at all. Under the London Agreement an English description is sufficient; a patent granted in German or French needs its description in English or Dutch.

The drawing exposure here is subtle and almost always missed, because it looks like a translation task rather than a drawing task. Under Rule 43(7) EPC, reference signs taken from the drawings are included in the claims in parentheses, where they increase clarity, and they are not construed as limiting. Those reference signs are claim text. When the claims are translated into Dutch, the signs travel with them.

So if anyone has renumbered the figures at any point between the original filing and grant, or regenerated them from a later CAD revision with different callouts, the Dutch claims now carry reference signs that no longer match the published drawings. Nobody catches it, because the translator is checking language and the attorney is checking the deadline. The check that needs to happen is a mechanical reconciliation of every reference sign in the claims against the figures as published, before the Dutch translation is filed.

Designs and trademarks go to BOIP, so 37 CFR 1.152 does not travel

There is no Dutch national design right. OCNL does not register designs at all. A design is protected in the Netherlands as a Benelux design registered at BOIP here in The Hague, as a registered Community design at the EUIPO, or through the Hague System at WIPO.

This matters because design drawing practice is where US rules travel worst. The requirements of 37 CFR 1.152, the surface shading that shows contour, the broken lines limited to visible environmental structure, the bar on solid black except to show the colour black or colour contrast, are USPTO rules for a USPTO design patent. They have no application at BOIP, which works from reproductions rather than formal patent drawings and applies its own standards.

Two further corrections are worth stating plainly, because both appear constantly in checklists. European designs are not an EPC matter in any form, so no provision of the EPC governs design figures.

And Rule 46 EPC, the old “Form of the drawings” provision, no longer exists: it was deleted with effect from 1 February 2023, together with Rule 49(3) to (12) EPC, as part of the EPO’s digital-transformation package, with the form requirements moved into a Decision of the President of the EPO published in the Official Journal. That change is precisely what allowed the EPO to begin accepting drawings filed electronically in colour or greyscale from 1 October 2025 without amending the Implementing Regulations. Any supplier still promising “Rule 46 EPC compliant” figures is quoting a rule that has not been in force for years.

Note the asymmetry that follows for a Hague client filing in both directions: the EPO now takes colour electronically, while OCNL still requires one dark colour with no petition available. Colour figures that are perfectly acceptable at the EPO must be converted to black line work for the Dutch national filing.

What The Hague files, and where a drawing dispute is decided

The Hague’s filing profile is unlike that of an industrial city, and the figures reflect it. Government and public-sector technology is a major source, with the ministries and the Netherlands Enterprise Agency concentrated here. The city is the seat of international law and arbitration, and The Hague Security Delta has made cybersecurity and security technology a genuine local cluster, which in patent terms means a steady flow of applications whose inventions are architectures and protocols rather than mechanisms.

Energy, including offshore wind and the applied-research work of TNO, is the third pillar, and the Westland greenhouse-horticulture cluster immediately to the south-west generates a continuous stream of controlled-environment and horticultural-technology filings. TU Delft is a few kilometres away and feeds spin-outs into the same ecosystem.

That mix skews the drawing workload towards block diagrams, flowcharts, network and system architectures and data-flow figures, which are exactly the figure types the Dutch text-matter rule constrains hardest. A security or govtech application needs its boxes labelled to be intelligible, and the permitted designations for electrical block and manufacturing diagrams are the narrow opening that makes that possible. Getting that balance right, enough text to be enabling, little enough to be admissible, is the core of competent patent drawing The Hague work in these sectors.

As for where it ends up: Article 80 of the Rijksoctrooiwet 1995 gives the District Court of The Hague exclusive first-instance jurisdiction over Dutch patent matters, covering infringement, validity and declarations of non-infringement, with appeal to the Court of Appeal The Hague. The UPC’s local division for The Hague has been operating since 2023, and its registry operations moved to the Netherlands Patent Office in 2024. For an applicant, the practical point is that the court construing your figures is in the same city as the office that accepted them, and it will read them against the claims as filed.

A pre-filing drawing checklist for a Hague application

Run this before anything is filed at OCNL or validated from an EPO grant:

1. A4 sheets, one side only, on durable white non-glossy paper, arriving unfolded and uncreased.
2. Margins at 2.5 cm top, 2.5 cm left, 2 cm right, 2 cm bottom, so the same sheet clears both the Dutch requirement and 37 CFR 1.84(g).
3. Strong, evenly drawn lines in one dark colour. No colour, no greyscale fills, no photographs, and no expectation of a petition.
4. Figures clearly separated and numbered consecutively across the complete set.
5. All CAD artefacts removed: title blocks, drawing numbers, revision tables, layer names, scale bars, watermarks and software footers.
6. Remaining text matter limited to the permitted indications, and in the same language as the description.
7. Every feature recited in the claims actually visible in at least one figure. In a registration system this is the check nobody else will perform for you.
8. Every reference sign in the claims reconciled against the figures as published, before any Dutch claim translation is filed.
9. Route confirmed as direct national or EPO validation, with no assumption of a PCT national phase, and no overlap that Article 77 would prohibit.
