Patent Drawing in Graz.

A patent drawing Graz engineer files is judged against Section 15 PAV and the Austrian Patent Office’s own applicant leaflet, and the Austrian standard is not the German one — the margins differ, the line rule is expressed as a 300 dpi reproduction test rather than a character-height floor, and Austria requires something Germany does not: the applicant’s name or file number on the drawing sheet itself. That matters more in Graz than anywhere else in Austria: Styria filed 435 inventions in 2025, second only to Upper Austria, and the country’s single largest patent applicant is headquartered here.

Which rules govern a patent drawing Graz applicant files

Austrian substantive patent law sits in the Patentgesetz 1970. The formal requirements that decide whether your sheets are accepted are much narrower and much less well known: Section 15 PAV (the Patent- und Gebrauchsmusterverordnung), as set out in the Austrian Patent Office’s applicant leaflet PA/GM 144. There is no Austrian equivalent of the MPEP and no standalone drawing manual — Section 15 PAV plus that leaflet is the whole code.

The document rules come first. White paper, free of folds and holes, not stapled or rolled, preferably 80 g/m², A4 portrait at 210 mm × 297 mm, printed on one side only, single column, left-aligned rather than justified. Landscape pages — a graphic or table that will not fit portrait — are rotated 90 degrees anticlockwise, and each page may carry only one text orientation.

Then the margins, which are the first thing an imported template gets wrong. Every sheet must keep a margin of at least 2 cm at the top, bottom and right, and at least 2.5 cm on the left. Page numbers go centred in Arabic numerals without delimiting characters, in the top or bottom margin. The applicant’s or representative’s internal file reference may be placed in the top margin. Line numbering is to be avoided.

• Black and white only — drawings are executed in black and white with clear lines thick enough to reproduce well at a resolution of 300 dpi
• Colour tints and photographs are inadmissible — the leaflet says so in terms, and with an exclamation mark: “Farbtönungen, Fotos etc. sind unzulässig!”
• Sections by hatching — cross-sections in drawings must be made recognisable by hatching
• Reference signs that reconcile — the parts of the figures carry consecutive reference signs of digits or letters; the same part must carry the same sign in every figure, and the signs must correspond with those in the description
• Figures clearly separated and numbered — where a drawing contains several figures they must be clearly separated and numbered consecutively, Fig. 1, Fig. 2 and so on
• Identification on the sheet — the drawings must carry the applicant’s name or, if known, the file number, placed in the page margin or on the reverse
• Line thickness judged by reproduction — the test is legibility at 300 dpi, not a stated minimum character height

The last two are the ones that catch firms filing into Austria from abroad. A US or German master set carries no applicant identification on the drawing sheet, because neither office asks for it. An Austrian set must.

The Graz industries that actually drive local filings

Graz is not a general-purpose filing centre. Its filings are powertrain, sensor, machinery and embedded-systems cases, which means sectional views, hatching and dense reference-sign apparatus — exactly the areas where the Austrian formal rules bite hardest. Each sector fails formalities in a characteristic way.

• Powertrain and vehicle testing engineering. AVL List, headquartered in Graz, was named the leading patent applicant in Austria in the Austrian Patent Office’s 2025 annual report with 179 patent applications — the fifteenth consecutive year it has topped the national ranking. These are instrumentation, simulation and test-bed cases, heavy on schematic block diagrams and sectional views.
• Contract vehicle manufacturing. Magna Steyr assembles complete vehicles in Graz for multiple marques. Body, chassis and assembly-process inventions generate exploded views and multi-sheet assemblies — the figures most likely to breach the “clearly separated” and consistent-scale requirements.
• Industrial machinery. Andritz AG is headquartered in Graz with roughly 1,800 employees locally, in hydropower, pulp and paper and separation plant. Those filings live on process and plant flow diagrams.
• Optical sensors and semiconductors. ams-OSRAM operates from Premstätten just outside Graz. Sensor and package cases need cross-sections at a scale where hatching and reference signs compete for the same few millimetres.
• Embedded systems and software. The Silicon Alps cluster links electronics and embedded-systems firms across Styria and Carinthia, and Green Tech Valley concentrates climate and clean technology around Graz. The figures here are flowcharts and state diagrams.

The regional numbers back this up. Styria recorded 435 inventions in 2025, making it the second most inventive Austrian federal state after Upper Austria, against a national total of 2,272 patent and utility model applications — up 4.4 per cent on 2024. For a city of its size, Graz is heavily over-represented in that figure.

Two practical risks follow from that mix. First, test-bed and plant diagrams exported from engineering software arrive covered in equipment tags, stream labels and unit captions; the reference-sign apparatus has to absorb that content instead. Second, sensor and semiconductor cross-sections are usually drawn at a scale where hatching swallows the numerals. The Austrian rule is explicit that hatching marks the section, and equally explicit that the same part must carry the same reference sign in every figure and match the description — so we open the hatching around each numeral rather than shrinking the type.

Why a Graz patent dispute is heard in Vienna

There is no patent venue in Graz, and there is no regional branch of the patent office either. The Austrian Patent Office sits in Vienna and serves the whole country, and patent infringement proceedings are concentrated there too.

The Vienna Commercial Court (Handelsgericht Wien) holds exclusive first-instance jurisdiction over patent infringement for all of Austria. Appeals go to the Higher Regional Court of Vienna (Oberlandesgericht Wien) and then, on points of law, to the Supreme Court (Oberster Gerichtshof). A Styrian manufacturer asserting or defending an Austrian patent is litigating in Vienna regardless of where the factory is.

Austria is also bifurcated, like Germany. Validity is not decided by the infringement court: a nullity action goes to the Nullity Department (Nichtigkeitsabteilung) of the Austrian Patent Office, with appeal to the Higher Regional Court of Vienna and then the Supreme Court. The Commercial Court tests whether a nullity defence is seriously arguable and, if it is credible, stays the infringement case pending that ruling.

Since June 2023 the Unified Patent Court runs alongside this. Austria ratified, and there is a Vienna local division of the UPC, so a classical European patent that has not been opted out, or a Unitary Patent, can be litigated there instead of at the Handelsgericht.

All of which makes the figures evidence rather than formality. A reference sign that appears in Figure 4 but was dropped from the description during prosecution, or a cross-section whose hatching obscures the numeral on the feature actually in dispute, becomes an argument about disclosure in front of a judge and a technical expert. Our Patent Invalidation in Graz and Prior Art Litigation Search in Graz teams work from the same sheets, which is why we build them to be read twice.

Austria’s drawing rules are not Germany’s

Firms running a DACH portfolio often assume one German-language master set covers Munich and Vienna. It does not, and the differences are small enough to slip through a review and large enough to draw an objection.

• Margins. Austria requires at least 2 cm top, bottom and right and 2.5 cm left. Germany’s Annex 2 PatV requires 2.5 cm top, 2.5 cm left, 1.5 cm right and 1 cm bottom. Neither set satisfies the other at the right and bottom edges.
• Usable area. Germany caps the area used for drawings at 26.2 cm × 17 cm. The Austrian leaflet sets no equivalent cap, working instead from the margins.
• Line and lettering standard. Germany fixes a floor of 0.32 cm for numerals and letters and tests legibility at a two-thirds reduction. Austria expresses the same idea as a reproduction test: lines thick enough to show well at 300 dpi.
• Identification. Austria requires the applicant’s name or file number on the drawings, in the margin or on the back. Germany does not.
• Figure labelling. The Austrian leaflet numbers figures in the form Fig. 1, Fig. 2. Germany requires consecutive Arabic numerals without prescribing that form.

What the two jurisdictions agree on is the hard part: black line work, no colour, no photographs, hatching for sections, and reference signs reconciled against the description in both directions. Our guide to patent drawings in Germany sets out the seven German rules in full, and the EPO drawing requirements guide covers the European layer.

The working rule for a patent drawing Graz filer is one black-line master plus route-matched derivatives, not one sheet set hopefully filed everywhere.

The utility model route Graz engineers overlook

Austria offers a utility model (Gebrauchsmuster) with a maximum term of ten years from the date of filing. It is the most under-used right in the Styrian toolkit, and for two reasons it fits the Graz filing profile unusually well.

First, there is no substantive examination. The Austrian Patent Office carries out a search and issues a report listing publications relevant to novelty and inventive step, and registration then proceeds regardless of what the search found. That turns the utility model into a fast route to an enforceable Austrian right for a process improvement or a piece of production tooling whose commercial life is well inside twenty years.

Second, and this is the genuinely unusual part, an Austrian utility model can protect program logic of a technical nature — though not microorganisms. For the embedded-systems and sensor firms in the Silicon Alps cluster that is a real option, and it has no equivalent in several neighbouring systems. The usual exclusions still apply: discoveries, scientific theories, mathematical methods, aesthetic creations, business schemes, games, computer programs as such, and perpetual motion machines.

The drawings get no relaxation. A utility model application carries the description, claims, abstract and any figures, and the Section 15 PAV standard applies exactly as it does to a patent. Because the office does not examine substance, formalities are a larger share of what actually gets scrutinised — and technical features cannot be added after filing without losing priority, so an incomplete figure set is not something you repair later.

Routes into Austria and what each does to your figures

The route decides the rulebook, so pick it before the sheets are finalised rather than after.

A direct national filing at the Austrian Patent Office puts you under Section 15 PAV in full. Austria does conduct substantive examination for patents — novelty, inventive step and industrial applicability — and the patent term is twenty years from filing, subject to annuities.

The PCT national phase at the Austrian Patent Office is open; Austria is not one of the EPC states that closed its national route. The deadline is 30 months from the priority date under both PCT Article 22 and Article 39 — not 31, which is the single most common docketing error on Austrian cases. A German translation is required within that period.

There is a fresh wrinkle if Austria is your receiving office. Since 1 April 2026 the Austrian Patent Office accepts colour and greyscale drawings in international applications on an informal basis — but the International Bureau converts them to black and white, so detail in the original can be lost. Filing colour there is permitted and still inadvisable; prepare the black-line version and keep control of what the published figure looks like.

Validating a European patent works on language. If the EP was granted in German, it takes effect in Austria automatically with no translation and no validation formalities. If it was granted in English or French, a full German translation is due within three months of the mention of grant in the European Patent Bulletin, and that deadline is not extendable and has no grace period. A foreign proprietor must act through a registered Austrian representative. Those drawings travel as granted by the EPO.

Note the divergence this creates. Since 1 October 2025 the EPO has accepted electronically filed colour and greyscale drawings under a Decision of its President. Austrian national practice did not move with it, so a colour figure set that is entirely proper at the EPO is not filable as-is in Vienna. Our PCT drawing requirements guide covers the international layer, where Rule 11.13(a) still demands black lines without colourings.

What a patent drawing Graz project includes

We work from whatever exists — CAD exports, test-bed schematics, process and plant flow diagrams, die or package cross-sections, photographs of a prototype, or a sketch on a whiteboard — and return filing-ready sheets for the route you are actually taking.

• A black-line master set built to Section 15 PAV, usable without modification for an Austrian patent or utility model filing
• Austrian margins applied correctly — 2 cm top, bottom and right, 2.5 cm left — rather than a German or US template reused
• The applicant’s name or file number placed in the margin or on the reverse of every sheet, as the Austrian leaflet requires
• Route-matched derivatives for the EPO, the PCT and the USPTO generated from the same master, so the family stays consistent
• One reference-sign table per family, reconciled against the description and claims in both directions, with identical parts carrying identical signs across every figure
• Cross-sections hatched so the section reads clearly while the numerals stay legible at 300 dpi
• Flowcharts and block schematics rebuilt so the labelling moves into reference signs instead of sentences on the sheet
• Figures separated and numbered Fig. 1, Fig. 2 in the Austrian form, with multi-sheet assemblies kept to a consistent scale

Clients normally come to us either before a first Austrian filing or after a formalities objection. The second is dearer, because by then the reference signs are embedded in the description and a renumber propagates through the text. See our full Patent Drawing services, or the companion team in Vienna.

Seven checks before a Graz filing goes out

• Every line is black on white, with no colour tint and no photograph anywhere on a sheet bound for the Austrian Patent Office
• Lines are thick enough to reproduce clearly at 300 dpi, and numerals inside hatched regions are still readable
• Margins are at least 2 cm top, bottom and right and 2.5 cm left on every sheet, with page numbers centred in plain Arabic numerals
• The applicant’s name or file number appears in the page margin or on the back of each drawing sheet
• Cross-sections are marked by hatching, and the hatching does not bury a reference sign or a leading line
• The same part carries the same reference sign in every figure, and every sign reconciles with the description
• Figures are clearly separated and numbered Fig. 1, Fig. 2, and the route is confirmed — national, utility model, PCT at 30 months, or EP validation — before the sheets are finalised

If any of the seven is unresolved, send the files before filing rather than after. A correction cycle in Vienna costs more time than getting the master right once.
