Patent Drawing in Dublin.

A patent drawing Dublin filing is prepared in one city and examined in another. The Intellectual Property Office of Ireland sits in Kilkenny; the attorneys, the in-house teams and the court that will eventually read your figures are in Dublin. Between them sits a filing profile that is unusual in Europe — a heavily multinational applicant base running Irish national applications, European applications and PCT filings in parallel, plus a short-term patent that is granted without substantive examination and capped at five claims. Each of those routes reads the drawings differently, and one of them relies on them almost entirely.

Why patent drawing Dublin filings answer to Kilkenny, Munich and Geneva

Start with the geography, because it catches people out. The Intellectual Property Office of Ireland — the IPOI, formerly the Patents Office — operates from Government Offices on Hebron Road in Kilkenny, not from the capital. Dublin is where the profession, the multinational IP functions and the courts are. In practice that means Irish filing work is coordinated in Dublin and formalities are answered to Kilkenny, and it is worth knowing which correspondence goes where before a deadline is running.

Ireland has been a European Patent Convention state since 1 August 1992, and for most commercially significant inventions the European route does the heavy lifting: a European application prosecuted at the EPO and validated back into Ireland on grant. Alongside it sit the Irish national application, the PCT route for the United States and Asia, and — for shorter-cycle products — the Irish short-term patent. One invention routinely carries a single set of figures through three or four formalities regimes.

Those regimes agree on most things. Sheet size, margins, line weight, view numbering and reference-character height are broadly harmonised across the IPOI, the EPO and the PCT. The divergences are narrow and specific — text on the sheet, colour, greyscale and photographs — and they are exactly the ones that surface after the filing date, when the only remaining option is a replacement sheet. Our practice for Dublin clients is to build one master figure set to the strictest common denominator and derive the office-specific variants from it, rather than reconciling divergent sets years later in a divisional.

Where an Irish patent dispute is actually heard

Ireland is not in the Unified Patent Court, and this is the single most important jurisdictional fact for an Irish patentee. Ireland signed the UPC Agreement but has not ratified it. Ratification transfers patent jurisdiction from the Irish courts, which requires a constitutional amendment and therefore a referendum. That referendum was announced for June 2024, pulled from the ballot before it was held, and the enabling Bill subsequently lapsed on the dissolution of the Dáil. There is no Irish local division of the UPC, and Irish patent disputes stay in the Irish courts.

Those courts are in Dublin, and they are better set up for patents than their size suggests. Substantial patent litigation goes to the Commercial Court, a division of the High Court running since January 2004, which case-manages commercial proceedings on a fast track before a limited pool of judges. Since 2021 there has been a dedicated Intellectual Property and Technology List within it, case-managed by a designated IP judge, covering registered and unregistered rights, passing off, confidential information and proceedings involving technological complexity.

The consequence for drawing work is direct. A bench that reads patents regularly will interrogate a figure against the description rather than treat it as decoration, and it will do so in English, in the language the figures were drafted in. Ambiguity in a figure stops being a formalities problem at that point and becomes a claim-construction problem. Figures prepared for an Irish or European filing are potential trial exhibits in a courtroom a short walk from most Dublin practices.

The Irish short-term patent: five claims, no examination, and figures that carry the load

Ireland’s short-term patent is where drawing quality stops being a formality and becomes the substance of the right, and it deserves more attention than it usually gets from applicants who arrive from other jurisdictions.

A short-term patent runs for a maximum of ten years rather than twenty. Its specification must not include more than five claims. Its inventive-step threshold is lower than the standard test: the invention need only be not clearly lacking an inventive step. And, critically, it is not substantively examined — neither a search report nor evidence of novelty in the form of a foreign patent specification is required for grant. Filing, grant and renewal fees run at half the full-term rate, which is what makes it attractive to individual inventors, spin-outs and SMEs.

Now put those three facts together. A right that is capped at five claims, granted without examination, and never tested until somebody attacks it, is a right whose disclosure has never been read by an examiner. If the figures are thin, nobody tells you at grant. You find out in the Commercial Court, or when a competitor requests that the patent be tested, by which point the filing date is long past and the prohibition on new matter is absolute.

With only five claims available, the drawings also have to do work the claims cannot. Detail that would sit in a dependent claim in a twenty-claim full-term specification has to live in the figures and the description instead, or it is simply not disclosed. We treat Irish short-term patent figure sets with the same rigour as a granted full-term patent’s, because functionally that is what they are being asked to be.

The contrast with the full-term route is worth stating. Irish full-term applications filed on or after 19 May 2017 are substantively examined for novelty, inventive step and industrial applicability, and the applicant must provide evidence of novelty through a search report. There, the drawings are read as part of a disclosure that somebody is actually checking.

Validating a European patent in Ireland: the London Agreement’s most generous case

Ireland became the twentieth contracting state to the London Agreement with effect from 1 March 2014, and because English is an official language of the State, Ireland sits in the most generous category the Agreement creates. No translation of the description is required, and no translation of the claims either — a granted European patent takes effect in Ireland without the translation exercise that a validation in a non-English state demands.

That is a genuine cost saving and a quiet trap. Because nothing is translated on an Irish validation, an English legend on a drawing sheet raises no issue here at all. The same figure set entering a non-English validation state is a different matter: drawings are not translated anywhere, so English text embedded in a figure stays English while the claims that reference it are rendered into another language. You end up with a translated claim set pointing at untranslated words on a sheet.

Irish applicants are therefore the ones most likely to build the habit that hurts them abroad, because their home validation never punishes it. The discipline is the one European practice already prefers: carry meaning in numbered reference signs, keep text in the figures to the minimum genuinely indispensable for comprehension, and let the description do the naming. It costs nothing at the drafting stage and removes an argument from an opponent’s hands a decade later.

What Dublin’s industries actually need drawn

Dublin’s filing profile is dominated by multinational R&D and by the spin-out ecosystem around Trinity College Dublin, UCD and the IDA-supported campuses, and it drives a specific mix of illustration work.

Pharmaceutical and biopharma filings come first. Ireland hosts a dense concentration of pharmaceutical manufacturing and process development, and the figures that come with it are rarely conventional line drawings — they are formulation schematics, process flow diagrams, assay outputs, dissolution and stability plots, and device cross-sections where a drug is paired with a delivery mechanism. Much of this work needs greyscale or colour handled deliberately rather than by default.

Software, data infrastructure and payments come second, and they are the largest single source of weak figure sets we see in this city. The European engineering functions of the major platform and cloud companies are here, along with a substantial fintech and payments sector, and the output is architecture diagrams, method flowcharts, state machines and message-sequence figures. The failure mode is always the same — a four-box flowchart that is formally compliant and discloses nothing.

Medical devices are third, with the honest caveat that Ireland’s medtech cluster is centred on Galway rather than Dublin. What lands in Dublin is the corporate and portfolio side of that industry, plus the diagnostics and connected-health work that sits between devices and software, which frequently pairs a utility filing with a design registration covering the same product — one project, two very different figure sets from the same CAD.

Typical Dublin deliverables:

• Process and formulation schematics for pharmaceutical and biopharma applications
• Architecture, flowchart and data-structure figures with enough granularity to support a later claim amendment
• Design registration figure sets with broken-line disclaimers, run alongside a utility filing
• Greyscale gels, blots and micrographs prepared to EPO reproduction standards
• Short-term patent figure sets built to full-term standard, because nothing else will test them
• Replacement sheets responding to IPOI or EPO formalities communications

Colour, greyscale and photographs: the European changes that matter here

Two European developments bear directly on the pharma and diagnostics work that dominates Irish filings.

The first is welcome. Since 1 October 2025 the EPO accepts and publishes greyscale and colour drawings, and drawings filed electronically in colour are published in colour. The old practice of scanning everything down to black and white — which quietly destroyed the information content of a stained section, a gel or a heat map — has ended. For applicants filing formulation and assay data as figures, this is the most useful drawing development in years.

The second is a citation trap. Rule 46 EPC, ‘Form of the drawings’, was deleted with effect from 1 February 2023, together with Rule 49(3) to (12) EPC, as part of the Administrative Council’s digital-transformation amendments. Those presentation requirements now sit in a Decision of the President rather than in the Implementing Regulations. A response to a formalities communication that cites Rule 46 EPC is citing a provision that no longer exists — and we still see it done.

Photographs remain the exception rather than an alternative. The EPC makes no express provision for them; the EPO Guidelines allow photographs where it is impossible to present in a drawing what is to be shown, provided they are directly reproducible and meet the applicable drawing requirements. Gels, blots, histological sections and crystalline structures qualify. A moulded housing does not, however good the product photography is — if it can be drawn, it must be.

One further point for Irish filers specifically: colour permitted at the EPO is not colour permitted everywhere. A set that will also enter a PCT phase in a jurisdiction that will not accept colour has to remain legible in greyscale. Designing for that constraint from the outset is far cheaper than re-plating a figure set halfway through a family.

How we work with Dublin attorneys and in-house teams

Most of our Irish work arrives in one of two states: CAD exports and inventor sketches at the drafting stage, or a formalities communication with a deadline attached. Both are routine. We work from STEP, DWG, SolidWorks and Creo exports, from raw assay and microscopy output, from architecture whiteboards, and from photographs where the figure has to become a line drawing rather than remain a photograph.

Deliverables come back as filing-ready PDF and TIFF sheets in the format the receiving office expects, with the editable source retained. That matters more in Ireland than most places, because a Dublin portfolio frequently produces a divisional, a continuation in the United States and a design registration years apart — and each of those should start from the same reference-character scheme rather than a fresh interpretation of it.

Dublin sits in the European working day and five hours ahead of the US East Coast, so a set queried by a Dublin attorney in the afternoon is generally answered before the next Irish working morning, and work coordinated with US counsel lands inside a single business cycle. Where a deadline is tight — an IPOI or EPO formalities response, or a hearing date in the Commercial Court’s IP and Technology List — we prioritise the sheets needed to meet the date and follow with the remainder.

A patent drawing Dublin checklist before the figures leave your desk

Most formalities objections on Irish files are avoidable, and they cluster around the same seven points. Running a set against this list before filing costs a few minutes and routinely saves a replacement-sheet cycle at the IPOI or the EPO.

• Every feature recited in the claims appears in a figure. List the claim elements and tick them off against the reference signs. On a five-claim short-term patent this is quick; on a full-term specification it is where amended claims and unamended drawings drift apart.
• Reference characters are consistent across every view. The same part carries the same numeral wherever it appears. Families drawn by different hands over several years break this silently.
• Every numeral in the figures appears in the description, and vice versa. An orphaned numeral is the most common formalities objection there is.
• Text inside the figures is minimal. Labels that could be numerals should be numerals. Ireland will never punish you for this; the next validation state will.
• Line weight survives reduction. Figures are reproduced and read below filing size. Hairlines and fine hatching that look correct on screen close up on the page.
• Views are numbered consecutively and prefixed correctly, and the numbering still matches the description after any late figure was added.
• The colour decision is made deliberately. The EPO will publish colour since October 2025, but the same set may need a greyscale variant for a PCT phase that will not accept it.

The short-term patent deserves one final word, because it is the route where this checklist earns the most. A right granted without examination, capped at five claims and never read by an examiner is a right whose entire technical disclosure rests on the description and the figures you filed on day one. What a patent drawing Dublin client does not need is to discover that in a courtroom on Inns Quay.

Where a set fails several of these points at once — typically an older family being extended into a new jurisdiction — it is usually faster to rebuild the master figures than to patch them. That is a judgement we will give you before quoting.
