A patent drawing Stavanger filing almost always starts as a CAD model. Rogaland’s engineering base builds subsea trees, manifolds, drilling tools and now carbon-storage and offshore-wind hardware, and the first instinct is to export the shaded render straight into the application. That is the one move Norwegian practice punishes, because Patentstyret converts published documents to greyscale. A render that reads beautifully on a workstation turns into grey mush in the published specification. The figures that survive are black line work with proper sectioning, and the sooner that decision is made the cheaper it is.
Where a patent drawing Stavanger application is actually filed
There is no patent counter in Stavanger. Norway runs a single office — Patentstyret, the Norwegian Industrial Property Office — and it sits in Oslo. Filings and validations are submitted electronically through Altinn, the national digital submission portal, so the absence of a local desk costs a Rogaland applicant nothing in practice. What it does mean is that nobody in Stavanger will look at your sheets before they are formally on file.
The substantive drawing obligation is short. Section 10 of the Norwegian Patent Regulations states that “[d]rawings shall show the details that are necessary in order to understand the description.” That is a disclosure test, not a formatting schedule: the question an examiner asks is whether the description can be followed from the figures, not whether a line weight matches a table.
Language is the other early decision, and Norway is unusually relaxed about it. Section 5 of the Regulations provides that the description, patent claims and abstract shall be in Norwegian or English. A Stavanger engineering team can therefore prosecute its home filing in the working language of the project, which is very often English on the Norwegian shelf.
The Patentstyret drawing formalities that actually get enforced
Patentstyret’s published application guidance is brief, and each line of it corresponds to a real objection. Drawings “should be numbered and collected on separate pages, and not placed in the description.” Engineers who assemble their specification in a word processor routinely breach this by dropping figures inline beside the text that discusses them. The figures have to come out and live on their own sheets.
Text on the sheet is tightly limited: “There should be no text on the drawing, apart from brief indications such as ‘water’, ‘steam’ or ‘closed’, which may be allowed.” Those examples are telling for a process-heavy filing. A flow label on a hydraulic circuit is the kind of indication the office contemplates. A block of explanatory prose lifted from the description is not, and neither is the title block that your CAD package stamps on every sheet by default.
Colour is a recommendation rather than a prohibition, and the reason matters: “We recommend filing drawings in black and white, since the documents are converted to greyscale upon publishing.” Norway does not ban a colour sheet the way Canada does. It simply publishes in greyscale, which means a colour figure is not rejected — it is degraded, silently, at the moment it becomes a public document.
Greyscale publication is the trap for subsea CAD
This is the point that separates a Stavanger filing from a generic one. Subsea and drilling hardware is modelled in SolidWorks, Inventor or Creo, and the natural export is a shaded, rendered perspective view. Shading carries the geometry in those exports: you read the curvature of a wellhead housing or the seating of a metal-to-metal seal from the gradient, not from a line.
Convert that to greyscale and the gradient collapses. Adjacent components that were distinguished by colour become the same mid-grey, the seal face disappears into the body, and a figure that was self-explanatory now needs the description to carry it. Nothing has been rejected; the disclosure has simply been weakened at the moment it is published, and it is published for the life of the right.
The fix is old-fashioned and reliable. Convert the model to black line work before filing, section through anything pressure-containing rather than relying on a surface render, and use hatching at a consistent angle so that each material in a sectioned assembly is distinguishable without colour. Keep lead lines clear of the hatched regions. An exploded view does more for a multi-part subsea assembly than any shaded render, because it survives greyscale intact.
What Rogaland energy engineering demands from a figure set
Stavanger is the operational centre of the Norwegian shelf. Equinor is headquartered in the city, the operator and supplier engineering offices cluster around Forus, and the Norwegian Offshore Directorate — Sokkeldirektoratet, renamed from the Norwegian Petroleum Directorate on 1 January 2024 — has its offices here. That rename is not cosmetic for anyone filing patents: the directorate’s remit now covers CO2 storage, offshore wind and seabed minerals alongside petroleum, and the local invention base has broadened the same way.
What all of that hardware shares is that it is mechanical, assembled and pressure-bearing, which is the profile where drawings do the heaviest disclosure work. In practice a Rogaland figure set needs sectional views through housings, connectors and seal stacks; exploded views for running tools and modular manifolds; and schematic figures for hydraulic and control circuits where the physical layout is irrelevant to the claim.
Carbon-storage and offshore-wind filings add a second pattern. Those inventions are frequently defined by a process or a system topology rather than a single component, so the figure set has to carry both a system-level schematic and detail views of whatever component the claims actually narrow to. Deciding which detail earns a figure is a claim-scope decision, and it is the one worth spending drafting time on. The University of Stavanger and the region’s research institutes feed the same pipeline from the academic side.
Validating a European patent in Norway: three months, and drawing text is in scope
Most Norwegian rights arrive by way of the EPO rather than a national filing, and the validation window is short. Patentstyret must receive the validation request and the validation fee no later than three months after the EPO has announced the grant. The validation fee is NOK 7,150. Documents go in through Altinn as separate, page-numbered files.
Norway acceded to the London Agreement with effect from 1 January 2015, which is what keeps the translation bill manageable. If the European patent was granted in English, only a Norwegian translation of the claims is required; the English description stands as it is.
If the patent was granted in French or German, the position changes and the drawings are expressly caught. Patentstyret then requires a translation of the title and the description — including drawing text — into either English or Norwegian. Any wording you left on a sheet therefore has a translation cost attached to it on validation, which is a second, purely commercial reason to keep text off the figures in the first place. Sequence listings do not need translating.
Norway is an EPC state outside the UPC, and Stavanger files are tried in Oslo
Norway has been a party to the European Patent Convention since 2008, so a European patent can be validated here. Norway is not an EU member, and that is the line that matters: the Unitary Patent has no effect on Norwegian territory and the Unified Patent Court has no jurisdiction here. A European patent validated in Norway becomes a Norwegian national right, enforced under Norwegian law, whatever happens to the same family before the UPC.
Venue is centralised in a way that surprises local engineers. Under section 63 of the Norwegian Patents Act, Oslo District Court (Oslo tingrett) is the mandatory first-instance venue for patent matters — infringement, revocation, entitlement and judicial review of Patentstyret decisions alike. A Stavanger operator suing a Stavanger supplier over a Stavanger-built tool still litigates in Oslo. From there the route runs to Borgarting Court of Appeal and then to the Supreme Court.
Administrative refusals take a different path first, through the Norwegian Board of Appeal for Industrial Property Rights (KFIR), with two months to bring a KFIR decision before the court. The practical consequence for drawings is the same in either forum: a concentrated bench of judges reads the figures as part of the specification, and a sectional view that unambiguously shows the feature you are asserting is worth more than argument about what a shaded render was meant to convey.
Rule 46 EPC is gone — cite the right European authority
Any Norwegian file that touches the EPO runs into a citation that is now wrong. Rule 46 EPC, which used to carry the form requirements for drawings, was deleted with effect from 1 February 2023, and its content moved into a Decision of the President of the EPO. Guidance that still points to “Rule 46 EPC” for the form of drawings is pointing at a provision that no longer exists. The working text is Part A, Chapter IX of the EPO Guidelines for Examination.
The substance also changed. Since 1 October 2025 the EPO accepts electronically filed drawings in colour or greyscale (Decision of the President, OJ EPO 2025, A49; Notice, OJ EPO 2025, A57), subject to adequate contrast and a minimum resolution of 300 dpi. The PCT did not follow: Rule 11.13 still calls for black, uniformly thick, well-defined lines without colourings.
For a Stavanger family that is a useful asymmetry to hold in mind, and it points one way. The EPO will now take your colour sheet, the PCT will not, and Patentstyret will publish it in greyscale regardless. One black-line master set satisfies all three; a colour master set satisfies exactly one of them and quietly degrades in the other two.
Seven checks before you file a patent drawing Stavanger application
Almost every objection and every avoidable cost on a Rogaland file traces back to something that was settled, or not settled, before the sheets were exported. This is the sequence we run on a patent drawing Stavanger package before it goes near Altinn.
- Export line work, not a render. Convert the CAD model to black outlines and then test it: desaturate the sheet to greyscale and ask whether you can still identify every component. If you cannot, neither can a reader of the published specification.
- Strip the CAD furniture. Title blocks, part numbers, revision stamps, drawing-office names and watermarks are added by default by every major package and none of them belong on a patent sheet. Removing them also removes an unnecessary translation liability.
- One figure per sheet, numbered consecutively. Pull every inline figure out of the description. Patentstyret’s guidance asks for drawings numbered and collected on separate pages, and this is the formality most often breached by word-processor assembly.
- Section anything that holds pressure. Wellhead housings, connectors, seal stacks and valve bodies need a cross-section, not a perspective view. Hatch at a consistent angle, vary it between adjacent materials, and keep the hatching clear of reference numerals and lead lines.
- Use an exploded view for assemblies. Running tools and modular manifolds disclose far more in an exploded view than in an assembled render, and the exploded view loses nothing in greyscale.
- Reduce on-sheet text to brief indications. Flow and state labels of the “water”, “steam”, “closed” variety are contemplated by the office. Anything longer is both a formalities risk and, if a European patent is later granted in French or German, a line item in the validation translation.
- Reconcile the numerals both ways. Every reference character on a sheet must be discussed in the description, and every numbered feature in the description must appear on a sheet. Late claim amendments are where this breaks.
None of these steps is expensive at the drafting stage. All of them are expensive once the application has published.

Frequently Asked Questions
Can I file a Norwegian patent application in English?
Yes. Section 5 of the Norwegian Patent Regulations provides that the description, patent claims and abstract shall be in Norwegian or English, so a Stavanger team can prosecute in the project’s working language. Note that validating a granted European patent is a separate exercise with its own translation rules.
Is there a patent filing desk in Stavanger?
No. Norway has a single industrial property office, Patentstyret, based in Oslo, and submissions are made electronically through the Altinn portal. There is no regional filing counter in Stavanger or anywhere else in Rogaland, so nothing about a Rogaland address changes the filing route.
Do patent drawings have to be black and white in Norway?
Not strictly, but they should be. Patentstyret recommends filing drawings in black and white because documents are converted to greyscale upon publishing. A colour or shaded render is not rejected; it is flattened at publication, which is why shaded subsea CAD exports lose the geometry they were relied on to show.
Does text inside a drawing need to be translated to validate in Norway?
It depends on the language of grant. If the European patent was granted in English, only a Norwegian translation of the claims is required. If it was granted in French or German, Patentstyret requires a translation of the title and description, expressly including drawing text, into English or Norwegian.
Does the Unified Patent Court cover Stavanger?
No. Norway is a party to the European Patent Convention but is not an EU member, so the Unitary Patent has no effect on Norwegian territory and the Unified Patent Court has no jurisdiction there. A European patent validated in Norway is enforced as a Norwegian national right.
Where are Stavanger patent disputes heard?
In Oslo. Section 63 of the Norwegian Patents Act makes Oslo District Court (Oslo tingrett) the mandatory first-instance venue for patent matters, including infringement and revocation, regardless of where the parties are based. Appeals run to Borgarting Court of Appeal and then to the Supreme Court.
