The deadline for entering the PCT national stage in Denmark is 31 months from the priority date, and this period can be reinstated within two months from the discovery of an error, provided it is not later than one year from the expiration of the deadline.
The minimum filing requirements set by the Danish Patent Office include a Danish or English translation or a copy of the application if it is in Danish or English, along with the payment of the filing fee.
The official languages for Danish PCT national phase applications are Danish and English. While the application can be submitted and processed in English, a Danish translation of patent claims must be supplied before the patent grant.
No legalization or notarization is required for the Power of Attorney (POA), and a scanned copy of the signed POA is sufficient.
The request for substantive examination is initiated at the time of entering the PCT national phase in Denmark by paying the filing fee, and an acceleration procedure is available.
A six-month novelty grace period applies, particularly if the disclosure results from evident abuse in relation to the applicant or display at an exhibition falling under the Convention on International Exhibitions.
The official grant fee for a Danish patent must be paid within two months from the Notice of Allowance, and the 1st-3rd maintenance fees are due by the end of the 2nd year of the patent application.
Utility Models (UM) can also be protected in Denmark with a formal examination. Substantive examination is conducted only if explicitly requested before or after registration, with payment of the examination fee. The UM is valid for 3 years from the international filing date and can be extended for up to 10 years by paying maintenance fees.
For foreign applicants, it is advisable to enter the PCT national phase in Denmark through a local agent, or a registered Danish patent attorney.
