A Danish patent or patent application needs an accurate annual-fee record from the first payment point through the end of its available term. The amount rises with the fee year, the deadline is tied to the filing history and a validated European patent becomes its own Danish maintenance stream after grant. NordicIP manages that work for foreign owners and overseas IP firms.
Our service is built around verification. We do not copy an inherited spreadsheet into a new diary and assume it is correct. We reconcile the case number, owner, filing date, route, status and last known payment with the Danish record before the next instruction is issued.
Which Danish rights require annual fees?
Annual fees apply to Danish national patent applications and patents. A European patent validated in Denmark is maintained nationally after the relevant EPO stage, so the Danish part must also appear on a national annuity calendar. The payment stream is separate from renewals due in Finland, Norway, Sweden or other validated states.
The first question is therefore not only “what is the patent number?” It is whether the matter is a national application, a granted Danish patent or a validated European patent, and which fee year is next. NordicIP records both the national identifier and any EP family reference so the owner can see the relationship without confusing the deadlines.
How the Danish fee year affects the deadline
The renewal schedule is calculated from the filing history. The initial payment covers the first fee years together; later payments fall annually. Special timing can arise when an international application enters the Danish national phase, when a European patent is granted close to a national due point or when a register event changes the ordinary calculation.
NordicIP checks the Danish office record and current official fee table for every instruction. The reminder states the right, fee year, ordinary deadline, official amount, NordicIP handling scope and the date by which cleared instructions and funds are required.
Current official fee structure
DKPTO publishes a year-by-year schedule. The fee rises as the patent becomes older, so a portfolio forecast should use the individual fee year rather than one flat official amount. The current 2026 table also shows that a payment made after the normal due date is increased by 20% and can be accepted within the stated six-month late period.
Official tariffs can change. We therefore quote against the live DKPTO schedule at instruction, not against an old invoice or an undated third-party chart. The client receives the official fee and our service fee as separate, intelligible components.
The ordinary NordicIP payment workflow
- Verify the case. We match the patent number, owner, filing data, status and payment history to the Danish record.
- Calculate the next action. We identify the fee year, normal deadline, current official amount and internal instruction date.
- Request authority. The reminder gives the owner or instructing firm one clear decision and a complete cost.
- Make and record payment. After authority and funds are in place, NordicIP completes the national payment under the correct case reference.
- Report completion. We send the receipt or payment evidence and update the next Danish annual-fee date.
Validated European patents in Denmark
A European patent family can produce several national renewal streams after grant. Denmark should be loaded as a separate jurisdiction with its own national identifier, owner position and first post-grant payment analysis. Relying only on the EP publication number can obscure the national action.
When NordicIP receives a newly validated Danish case, we check the grant and validation details, identify the first national fee requiring action and place it beside the other Nordic validations. The client can then send one consolidated instruction while each payment is executed and reported nationally.
Late payments and approaching expiry
A missed ordinary deadline does not automatically mean that no action remains. DKPTO’s published rules provide the six-month late-payment route with the increased fee. However, the remaining time should be calculated from the official due date, not from the date an internal reminder was opened.
When a late case is sent to us, mark it urgent and provide the full payment history. We verify whether the late route remains open, confirm the increased official amount and set a cleared-funds deadline that leaves time for payment and evidence. Re-establishment after the available payment period is a different and fact-dependent procedure; it should never be treated as an ordinary renewal method.
Portfolio transfer checklist
- Danish application or patent number and any EP publication reference;
- owner name and current address;
- filing date, national-phase or validation information;
- next deadline and fee year shown on the outgoing docket;
- last receipt or proof of payment;
- any lapse, late-payment or ownership-change history; and
- the person authorised to give payment instructions.
Send the list through the NordicIP patent annuity enquiry. We will confirm the accepted Danish cases, discrepancies, upcoming dates and the scope for integrating them with the wider Nordic annuity service.
