DKPTO conducts formality examination and substantive examination of invention patent applications. Danish patent applications can be filed and examined in English, but when the patent is granted the Claim need to be translated into Danish. The substantive examination starts automatically, and there is no need for the applicant to submit a request for substantive examination. DKPOT will conduct novelty search and patentability examination, and the applicant will receive the first search report within 6 to 7 months from the date of application. The patent application will be granted in about 1-3 years after the grant conditions are met.
