Patent Drawing in Hamburg.

A patent drawing Hamburg inventors can actually file is shaped by two facts about this city. Its signature industry is aviation — Hamburg is the third-largest civil aviation location in the world, and cabin and MRO inventions are assemblies inside assemblies that need exploded, sectional and in-situ views on a 26.2 × 17 cm sheet. And unlike most German cities, Hamburg has somewhere to file: the Handelskammer’s Innovations- und Patent-Centrum accepts documents on behalf of the DPMA. Neither of those changes the standard your figures are measured against, which is Annex 2 to the Patentverordnung — nine clauses, no photographs, no colour, and no petition route.

Where a patent drawing Hamburg filers submit actually goes

Unlike most German cities, Hamburg has a counter. The Innovations- und Patent-Centrum (IPC) at the Handelskammer Hamburg, Adolphsplatz 1, 20457 Hamburg is Hamburg’s Patentinformationszentrum, and it accepts documents relating to industrial property rights on behalf of the DPMA — which makes it a receiving office for a German patent application, not merely an advice desk. It also runs a first-consultation slot for inventors on Thursday afternoons.

What it does not do is review your figures. The German Patent and Trade Mark Office itself sits in Munich, with further locations in Jena and a Technical Information Centre in Berlin. There is no DPMA examining presence in Hamburg. Whether you hand your set across the counter at Adolphsplatz or upload it through DPMAdirektPro, the sheets you submit are the drawings of record, and the first substantive look at them comes from an examiner 600 kilometres away.

So a patent drawing Hamburg applicants commission is a pre-filing deliverable. Once the application is on file, a defective figure is no longer a formatting question — it is an official communication with a response deadline, and in the worst case a re-dated filing.

Annex 2 PatV: the nine clauses your Hamburg figures are measured against

German drawing law is remarkably compact. Section 12 of the Patentverordnung (PatV) says only that submitted drawings must comply with the standards contained in Annex 2, and Annex 2 is nine numbered clauses. There is no German equivalent of the MPEP. That brevity is the trap: the DPMA reads each clause broadly, and an imported US set can satisfy rules Germany never wrote while breaching ones it did.

• Sheets and margins. DIN A4 (21 × 29.7 cm), one side only. Minimum margins of 2.5 cm at the top, 2.5 cm at the left, 1.5 cm at the right and 1 cm at the bottom. The area actually used for drawings may not exceed 26.2 × 17 cm.
• Line work. “Durable, black, sufficiently dense and dark, uniformly thick and clearly delineated lines and strokes, without colourings.” There is no petition route and no fee that buys an exception — contrast 37 CFR 1.84(a)(2), under which a US utility applicant can petition for colour.
• Permitted forms. Views, sectional views, perspectives and exploded views. Cross-sections by hatching that should not impede the clear reading of the reference signs. Photographs are not among the permitted forms — a direct divergence from 37 CFR 1.84(b), which admits a photograph where it is the only practicable medium.
• Reproduction. Everything must remain legible after electronic capture at a linear reduction to two-thirds.
• Lettering. Drafting instruments, not freehand. Numerals and letters at least 0.32 cm high, in the Latin and (where customary) Greek alphabets.
• Figure numbering. Several figures per sheet, arranged without wasting space, clearly separated, preferably portrait, numbered consecutively in Arabic numerals. Uniform scale across split figures. Prior-art drawings are admissible only if marked “Stand der Technik”.
• Reference signs. Signs that do not appear in the description or claims must not appear in the drawings — and the reverse also holds.
• Text matter. None, except indispensable words such as “water”, “steam”, “open”, “closed” or “section on AB”, plus a few short catchwords for electric circuits, block schematics and flow sheets.
• File formats. The electronic-format table admits 1-bit TIFF, 8-bit greyscale TIFF and 24-bit JPEG at 300 × 300 dpi. Those are containers, not permissions: clause 2 still governs the content, so the table does not license colour.

Our full treatment of the German rules sits in patent drawings in Germany.

Aviation: Hamburg’s hardest drawing problem

Hamburg is the third-largest civil aviation location in the world. The cluster employs over 40,000 skilled professionals: Airbus at Finkenwerder — A320-family final assembly plus the cabin and cabin-systems work that makes Hamburg the group’s centre of gravity for interiors, with up to 18,000 people across Finkenwerder, Stade and Buxtehude — and Lufthansa Technik, headquartered in the city with more than 8,000 employees on site and the world market leader in MRO.

Cabin and MRO inventions are the most demanding figure work we see out of Germany, for three structural reasons.

• Everything is an assembly inside an assembly. A galley insert, a seat-mounted power module or a lavatory monument has to be shown in situ, exploded, and in section. Annex 2 clause 3 permits exploded views and perspectives explicitly, which is the clause to lean on — but clause 6 then demands a uniform scale across split figures, and a monument drawn at one scale with its interface bracket at another will be objected to.
• Retrofit inventions sit on existing airframes. If the figure shows the host structure as it already exists, that part of the drawing is prior art. Annex 2 clause 6 admits prior-art drawings only if marked “Stand der Technik”. Unmarked, the sheet reads as though you are claiming the airframe.
• Composites and surface finishes tempt photography. They cannot be photographed into a German application. Clause 3 has no photograph exception. A layup, a bondline or a fatigue surface has to be redrawn as hatched line art.

Port logistics and cargo handling: very large machines on a 26.2 cm sheet

The Port of Hamburg is Germany’s largest seaport, and the terminal-automation, container-handling, crane and intermodal technology built around it generates a steady filing load. These inventions share one awkward property: the machine is enormous and the sheet is 26.2 × 17 cm.

Annex 2 gives you the tools, but they have to be used deliberately. A gantry crane or an automated stacking system is drawn as an overall view at a scale where nothing is legible, then as a sequence of detail figures at a usable scale — and clause 6’s uniform-scale requirement applies within each split figure, not across the set, so the detail figures may differ in scale from the overview provided each one is internally consistent.

Control logic is the other half of the problem. Terminal automation is largely software and sensing, and Annex 2 clause 8 allows “a few short catchwords” for block schematics and flow sheets — genuinely a few. A flowchart carrying full sentences in each box is irregular, and the fix is to move the prose into the description and leave numerals in the boxes. We work through that pattern in patent diagrams.

Wind energy and metals: the greyscale trap

Hamburg is the headquarters city for Nordex SE in onshore wind, and for Aurubis AG, Europe’s largest copper producer and recycler. Both file heavily, and both run into the same clause.

Annex 2 clause 9 admits 8-bit greyscale TIFF and 24-bit JPEG at 300 dpi as electronic file formats. Draftspeople read that as permission to shade, and it is not. Clause 2 still requires black lines without colourings; clause 9 only describes the containers the DPMA will accept. A greyscale-rendered blade cross-section or a tonally shaded nacelle assembly is irregular even though the file format is on the list.

For metallurgy the constraint bites harder. A micrograph showing grain structure in a copper alloy is a photograph, and photographs are not a permitted form under clause 3. The microstructure has to be redrawn as line art with hatching, which means deciding in advance which features are claim-relevant. That is a drafting decision, not a drawing decision, and it belongs in the conversation before anyone opens a CAD file.

Hamburg’s research base keeps that pipeline full: DESY in Bahrenfeld, the Technische Universität Hamburg in Harburg, and the University Medical Center Hamburg-Eppendorf on the life-sciences side, where the same no-photograph rule governs device figures. See patent drawings for medical devices.

Where a Hamburg patent dispute is actually heard

Hamburg is one of the few German cities where both patent court systems sit, and the distinction decides which figure set gets read.

• German national patents and unopted-out European patents. Section 143(2) of the Patentgesetz lets the Länder concentrate patent disputes, and twelve Landgerichte carry patent chambers. The Landgericht Hamburg is one of them, and it is among the four most regularly seised in Germany alongside Düsseldorf, Mannheim and Munich I. Appeals go to the Hanseatisches Oberlandesgericht in Hamburg, then to the Bundesgerichtshof in Karlsruhe.
• Bifurcation. German infringement courts do not decide validity. A nullity action goes to the Bundespatentgericht in Munich, on a separate timetable. Your drawings are therefore read twice, by two benches, for two different purposes — support and disclosure in Munich, scope in Hamburg.
• Unitary patents and non-opted-out European patents. Germany has four UPC local divisions, and one of them is here: the Local Division Hamburg at Sievekingplatz 1, 20355 Hamburg, with two legally qualified judges. The UPC’s central division is seated in Paris with a Munich section for IPC class F.

One correction worth making in your templates before any of that: Rule 46 EPC, “Form of the drawings”, was deleted with effect from 1 February 2023. The form of drawings in European applications is now set by a Decision of the President of the EPO, which is how the EPO was able to begin accepting colour and greyscale drawings on 1 October 2025 without amending the Implementing Regulations. See EPO drawing requirements.

Patent drawing Hamburg: how we prepare a figure set

We work from whatever you have — CATIA or SolidWorks assemblies, a Lufthansa Technik-style retrofit sketch, a terminal-automation block diagram on a whiteboard, lab micrographs, or a draft specification with no figures at all.

1. Route first. DPMA national, Gebrauchsmuster, EP via the EPO, or a 31-month PCT national phase at the DPMA? Each has a different drawing standard, and the German PCT national phase additionally requires a German translation of any text matter in the drawings.
2. Numeral reconciliation. Every reference sign in the description checked against the sheets, and every sign on a sheet checked back against the description — Annex 2 clause 7 runs in both directions, and this is the single most common objection we clear.
3. Annex 2 formatting. Margins at 2.5 / 2.5 / 1.5 / 1 cm, used area inside 26.2 × 17 cm, lettering at 0.32 cm or above, black line work with no greyscale, hatching that leaves the reference signs readable.
4. Prior-art marking. Anything showing the existing host structure marked “Stand der Technik”.
5. Two-thirds test. Every sheet reduced to two-thirds linear and re-read before delivery.
6. Cross-office variant. Where the same invention is going to the USPTO or the EPO, we deliver a second set built to the strictest value on each edge so one master drawing clears both offices.

Figures come back as print-ready PDF plus editable source, with a formalities note on anything that needed a drafting decision rather than a drawing one.
