Patent Drawings in Poland: 7 Critical UPRP Sheet Rules

Most formal drawing standards across the major offices have quietly converged. Poland is the exception that still catches people out. The rules governing patent drawings in Poland live in an annex to a twenty-five-year-old ordinance, and one of them sets a left margin on drawing sheets that is a full centimetre wider than the figure the USPTO and the PCT both accept. Reuse an American sheet in Warsaw and the geometry is wrong before anyone looks at the invention. The Patent Office of the Republic of Poland (UPRP) treats that as a formal defect, not a stylistic preference.

Which Rulebook Governs Patent Drawings in Poland

Poland splits its drawing law across two instruments, and the one that matters is the less obvious of the pair. The Industrial Property Law (Prawo własności przemysłowej, the Act of 30 June 2000) does the high-level work. Article 31(2) says a patent application should contain drawings if they are necessary to understand the invention. That is the whole of the statutory requirement for patents.

Everything about how a figure must look sits in the Ordinance of the Prime Minister of 17 September 2001 on the filing and examination of applications for inventions and utility models (Dz.U. 2001 No. 102, item 1119). It has been amended several times — most recently with effect from 30 November 2016 — and it remains in force. The UPRP’s own filing-documentation guidance still cites it to applicants as the governing text, and asks for the drawings in one copy.

Within that ordinance, § 10 deals with drawings as a matter of substance: the figures must show the subject of the invention in as many views as its complexity requires for the invention to be understood alongside the description and claims. Individual figures may carry sections and specific parts of the subject matter.

The formal requirements — paper, sheet size, margins, line quality, lettering, numbering — are collected in Annex 1 to the ordinance, a list of thirty-one numbered points. Annex 1 is short, and it is where nearly every avoidable objection originates. The seven rules below are the points that most often diverge from what a non-Polish drafting team will already have on file.

• National UPRP filing — the ordinance and Annex 1 apply in full.
• PCT national phase at the UPRP — the national route is open, and Annex 1 governs the Polish phase.
• European patent validated in Poland — the figures were assessed under EPO practice; Annex 1 does not apply retrospectively.
• Utility model (wzór użytkowy) — § 16 applies § 10 and Annex 1, with one extra requirement of its own.

Rule 1: The 35 mm Left Margin That Breaks Imported Sheets

This is the single most useful thing to know about Polish drawing practice, and it is buried in point 10 of Annex 1. The minimum margins on sheets containing drawings are:

• Top margin: 25 mm
• Left margin: 35 mm
• Right margin: 15 mm
• Bottom margin: 10 mm

Three of those four match the figures an American or PCT drafter already works to. Under 37 CFR 1.84(g), the USPTO requires a top margin of at least 2.5 cm, a left margin of at least 2.5 cm, a right margin of at least 1.5 cm and a bottom margin of at least 1.0 cm. PCT Rule 11.6 sets the same numbers for A4 sheets.

The left margin is the outlier. Poland asks for 35 mm where the USPTO and WIPO ask for 25 mm. A sheet drawn to the American minimum is non-compliant in Poland by one centimetre, and nothing on the face of the drawing reveals the problem. This is the defect we see most often in sets arriving from US counsel.

Annex 1 adds two constraints that interact with the margins. Point 11 forbids frames and any single line separating a margin from the rest of the sheet — so the common practice of boxing a drawing is not available. Point 12 requires the margins to be clean, which rules out the drafting-office habit of parking sheet numbers, file references or firm names in the white space.

Sheets are A4 (297 mm by 210 mm) under point 8, used in portrait orientation with the shorter sides at top and bottom under point 4, and only one side of each sheet may be used under point 3. Point 5 calls for flexible, strong, white, smooth, opaque and durable paper, and expressly permits drawings on tracing paper.

Rule 2: Black Lines Only, and No Colour

Point 23 of Annex 1 requires drawings to be executed in durable, black, intense and sharply defined lines. There is no petition procedure attached to it and no exception for figures that are hard to render in line work.

WIPO’s PCT Applicant’s Guide national chapter for Poland confirms the position in terms for anyone entering the national phase. Against the question of whether the Office accepts colour drawings under its national law, the entry for Poland reads: No. The same chapter records that Poland’s receiving Office will not accept colour drawings on an informal basis for transmittal to the International Bureau either.

The ordinance also makes no provision for photographs. Annex 1 prescribes how lines are to be drawn and says nothing that would admit a photographic print, which is a meaningful divergence from US practice. 37 CFR 1.84(b) lets the USPTO take photographs in utility and design cases where photographs are the only practicable medium — gels, blots, crystalline structures, in vivo imaging — and 37 CFR 1.84(a)(2) allows colour drawings on a granted petition. Neither escape hatch has a Polish counterpart.

Where colour was carrying meaning, that meaning has to move into line work: hatching, stippling, varied line weights and reference signs. Point 24 expressly contemplates hatching for sections, provided it is done according to technical-drawing convention and does not make the lead lines and main lines harder to read. Our note on patent drawing shading requirements covers how far shading can be pushed before it starts obscuring detail.

Keep industrial designs in a separate mental compartment. A Polish industrial design (wzór przemysłowy) is a different right with its own representation rules, and Annex 1 is not the standard for it; registered Community designs go to the EUIPO and the Hague system offers a further route. The US analogue is also distinct: under 37 CFR 1.152, a design must be represented by a drawing complying with 37 CFR 1.84 and must contain a sufficient number of views to constitute a complete disclosure of the appearance of the design. Reasoning from design practice to Polish patent figures, or the reverse, is how avoidable objections get generated.

One overarching test governs all of this. Point 1 of Annex 1 requires every part of the application — description, claims, drawings and abstract — to be fully legible in all details after reproduction at two-thirds linear reduction. A figure that survives at full size but closes up when shrunk fails the rule even if every individual line is black.

Rule 3: Almost No Text on the Sheet

Point 22 is strict about lettering in a way that catches diagram-heavy filings. Drawings should not contain text, with an exception for single words where they are genuinely necessary. The ordinance gives its own examples — woda (water), para (steam), otwarte (open), zamknięte (closed), przekrój AB (section AB).

There is a narrow concession for schematics: a few words may be placed in process-flow diagrams and block diagrams where they are indispensable to understanding the schematic. That concession is what makes software, chemical-process and control-system cases workable at all, but it is not a licence to label every block with a sentence.

The practical consequence is that labels have to become numbered reference signs carried in the description. For a flowchart-led software application this can mean redrawing rather than relabelling, which is worth scoping before a deadline rather than during one.

Whatever words do survive on the sheet become a translation obligation. The PCT Applicant’s Guide chapter for Poland requires the Polish translation furnished on national phase entry to cover any text matter of drawings, alongside the description, claims and abstract. Fewer words on the sheet is therefore also the cheaper option.

Rules 4 and 5: Lettering Height and Figure Numbering

Point 27 sets a floor on lettering: digits and letters on drawings must not be less than 3.2 mm high. This is one place where Poland and the United States agree exactly — 37 CFR 1.84(p)(3) sets the same 0.32 cm minimum. It is a physical height on the sheet rather than a point size, so it moves whenever the figure is rescaled. Shrink a crowded figure to fit the margins and the numerals can drop below the threshold while the drawing still looks fine on screen.

Point 25 governs how those characters are presented. All digits, letters and lead lines must be clear, and digits and letters must not be enclosed in brackets, circles or quotation marks. Circled reference numerals are a common house style in European engineering drawings, and they are not available here.

Point 28 covers layout. More than one figure may sit on a sheet provided the figures are clearly separated from one another, vertical orientation is recommended, and figures must be numbered consecutively in Arabic numerals. Point 13 then requires the sheets themselves to be numbered consecutively in Arabic numerals, centred at the top of each sheet below the top margin — a separate numbering series from the figures, and easy to conflate.

Point 26 adds a proportionality requirement: all elements of a given figure must be in correct proportion to the other elements of that figure, unless a different proportion is indispensable to the figure’s legibility. That last clause is the authority for an enlarged detail view, and it is worth knowing it exists before an examiner queries a deliberately exaggerated feature.

Rule 6: Reference Signs Must Reconcile in Both Directions

Point 29 states the obligation symmetrically, and this is where otherwise clean sets fail. Reference signs that do not appear in the description must not appear on the drawings — and conversely, the description must not use reference signs that are absent from the drawings. Signs denoting the same element must be identical throughout the whole application.

That two-way reconciliation is unforgiving in practice. Amend a claim set, drop a figure, or cut a paragraph from the description late in the day, and the orphaned numeral on the other side of the file is a formal defect. The same discipline we describe for patent drawing reference numerals applies, with the difference that in Poland both directions are expressly covered.

Point 31 offers a sensible mitigation: where the drawings carry many reference signs, the ordinance recommends attaching a separate sheet listing every reference sign against the name of the element it denotes — a wykaz oznaczeń. It is a recommendation rather than a requirement, but it makes the reconciliation auditable and is cheap to produce.

Two related provisions sit outside the annex. Under § 11, the abstract must state the number of the figure that best illustrates the invention, and reference signs in parentheses should follow each main technical feature mentioned in the abstract. The claims, meanwhile, should not refer to the description or drawings by phrases such as "as in the figure", except where such a reference is indispensable, although reference signs in parentheses after the recited features are provided for.

One classification point is easy to miss. Under § 10(3), chemical structural formulae presented on separate sheets count as drawings, and where later provisions speak of figures they include those formulae — which are labelled as a formula (wzór) rather than as a figure. A chemistry case can therefore acquire drawing sheets, and drawing-sheet margins, without anyone having drawn an apparatus.

Rule 7: Utility Models Must Have Drawings; Patents Need Not

The patent and utility model regimes diverge here, and the difference is statutory rather than procedural. Article 31(2) makes drawings conditional for patents — required only where necessary to understand the invention. Section 10(2) of the ordinance adds that where the nature of the invention permits illustration but drawings are not indispensable to understanding it, the applicant may include them anyway.

For utility models the position is the opposite. Article 97(2) provides that a utility model application contains drawings presenting the essential technical features of the model. There is no necessity test to argue about: a Polish utility model application without drawings is incomplete.

Section 16 then carries the drawing machinery across, applying §§ 5 to 8, § 9 point 1 and §§ 10 to 14 to utility model applications, so Annex 1 governs the sheets in the same way. It adds one requirement with no patent equivalent: under § 16(4), utility model drawings should, where needed, show a general view of the subject matter on the figure numbered 1. Figure 1 is not a free choice.

Poland’s utility model is a live option rather than a legacy one, which is worth saying because several jurisdictions have withdrawn theirs — Australia phased out the innovation patent from August 2021. A Polish utility model application may contain only one independent claim and covers only a single solution, so the drawing set tends to be tighter and the general view carries more of the disclosure.

Routes into Poland and What Each Does to Your Figures

Which rulebook applies depends entirely on how you arrive, and the three routes treat drawings differently.

A national filing at the UPRP is assessed against the ordinance and Annex 1 in full. A PCT national phase entry is too, and the deadline is the point to diary carefully: WIPO’s national chapter for Poland gives 30 months from the priority date under both PCT Article 22(1) and Article 39(1)(a). That is 30, not the 31 months several neighbouring offices allow, and assuming the longer period is an expensive mistake. The Polish translation must cover any text matter of the drawings.

A European patent validated in Poland is the different case. Those figures were examined under EPC practice, so Annex 1 never applies to them. Poland has been an EPC contracting state since 1 March 2004. It is not a party to the London Agreement, so validation requires a full Polish translation of the specification rather than the claims alone — and the words left on the drawings fall within it. The deadline is three months from publication of the mention of grant in the European Patent Bulletin, and it is both non-extendable and non-restorable. Our guide to validating a European patent in Poland sets out the mechanics.

The EPO route also diverges on the substance of the figures, and recently. Rule 46 EPC no longer exists. Rule 46 and Rule 49(3) to (12) EPC were deleted with effect from 1 February 2023, and the form requirements for drawings moved into a Decision of the President of the EPO published in the Official Journal. Since 1 October 2025 the EPO has accepted drawings filed electronically in colour or greyscale, provided they are contrast-rich and clear at 300 dpi. Any source still describing Rule 46 EPC as the live standard for European drawings is out of date — we set the current position out in our note on EPO drawing requirements.

The PCT itself did not follow the EPO. PCT Rule 11.13(a) still requires drawings to be executed in durable, black, sufficiently dense and dark lines without colourings, which is why the international standard and the Polish standard remain aligned on colour while the EPO has moved. The comparison in PCT drawing requirements is the useful cross-check before a multi-office set is finalised.

On representation, the rule is narrower than it is often stated. An agent — a registered Polish patent attorney, rzecznik patentowy — must be appointed where the applicant has neither a residence nor a principal place of business in Poland or in another EU or EFTA member state. An applicant established elsewhere in the EU does not need Polish representation on that ground; a US or Japanese applicant does.

Where Drawing Defects Actually Cost You

Formal objections are the cheap failure mode. The UPRP issues a notice, replacement sheets go in, and the cost is a few weeks and a fee. The expensive failure mode is a drawing that is formally clean but substantively thin, because the figures are part of the disclosure and define what can later be amended to.

Poland has had specialised intellectual-property divisions in its regional courts since 1 July 2020. The Regional Court in Warsaw holds exclusive jurisdiction over technical cases — patents, supplementary protection certificates and computer programs — with appeal to the Court of Appeal. Because Poland is outside the Unified Patent Court, a European patent validated there is litigated nationally, and the UPC has no jurisdiction over the Polish part.

That matters for figures because a single national court, repeatedly seeing the same technology, develops settled expectations about what a drawing set should show. A view that was omitted to save a sheet at filing cannot be added later without adding matter, and an enlarged detail that was never provided is not available to support a narrowing amendment under pressure.

There is a drafting consequence worth stating plainly. The views you will want in an infringement or validity dispute — the sectional view through the feature that distinguishes the prior art, the exploded view that shows an assembly order — have to be in the application on the filing date. Section 10(1) gives you the authority to include as many views as the complexity of the subject matter requires. Using that allowance generously is cheaper than any later argument about it.

A Pre-Filing Checklist for Patent Drawings in Poland

Run a set through this before it goes to the UPRP. Each item maps to a numbered point of Annex 1 or a provision of the ordinance, so an objection can be traced back to its source.

1. A4 sheets, 297 mm by 210 mm, portrait, one side only (points 8, 4, 3).
2. Margins at least 25 mm top, 35 mm left, 15 mm right, 10 mm bottom — check the left margin specifically against any imported set (point 10).
3. No frame and no line separating any margin; margins clean of annotations (points 11, 12).
4. Lines durable, black, intense and sharp; no colour; no photographic prints (point 23).
5. Fully legible at two-thirds linear reduction (point 1).
6. No text beyond indispensable single words, with the narrow concession for process and block diagrams (point 22).
7. Digits and letters at least 3.2 mm high, not enclosed in brackets, circles or quotation marks (points 27, 25).
8. Figures numbered consecutively in Arabic numerals and clearly separated; sheets separately numbered centre-top below the margin (points 28, 13).
9. Reference signs reconciled in both directions against the description, and consistent throughout; attach a wykaz oznaczeń if there are many (points 29, 31).
10. Utility model only: figure 1 shows a general view of the subject matter (§ 16(4)).
11. Abstract names the figure that best illustrates the invention, with reference signs in parentheses after the main features (§ 11).

If one item earns the extra minute, it is the left margin. It is the only dimension where a sheet drafted to USPTO and PCT minimums is wrong in Poland, and it is invisible unless somebody measures it.

Need Poland-Compliant Figures Without a Redraw Cycle

We prepare and remediate figures for the UPRP national route, PCT national phase entry and Polish validation of European patents, and we check sheets against Annex 1 point by point before they are filed. If you have a set built for the USPTO that now has to work in Poland, the margin and lettering audit is quick and it is the cheapest point in the process to fix.
