🇩🇰 Denmark · Trademark & IP
Trademark registration, patents, copyright, official IP offices, and filing costs.
Quick answer
Danish trademarks are registered with the Danish Patent and Trademark Office (DKPTO). You search the register, file under Nice classes, and after examination the mark registers and is published with a two-month opposition period. A Danish trademark lasts 10 years and is renewable; an EU-wide alternative is the EU trademark via EUIPO, and copyright arises automatically.
Trademarks, patents and designs are registered with the Danish Patent and Trademark Office (DKPTO); EU-wide protection is available through the EUIPO.
- Danish trademarks, patents and designs are filed with the DKPTO.
- An EU trademark (EUTM) at the EUIPO protects the mark across all EU member states.
- International protection can be extended via WIPO's Madrid (trademarks) and PCT (patents) systems.
