Patent Laws in Denmark
1. Governing Law
The main law regulating patents in Denmark is the Danish Patent Act (Patentloven).
Patents are administered by the Danish Patent and Trademark Office (DKPTO) — Patent- og Varemærkestyrelsen.
2. Patentability Requirements
To be patentable in Denmark, an invention must be:
Novel: Not publicly disclosed anywhere in the world before the filing date.
Inventive Step (Non-obvious): Must not be obvious to a skilled person.
Industrial Applicability: Capable of being made or used in any kind of industry.
3. Patentable Subject Matter
Patents can protect inventions such as products, processes, machines, and compositions.
Software as such is excluded but inventions with a technical effect involving software may be patentable.
Medical treatments and diagnostic methods are generally excluded.
Biological material and biotechnology inventions are patentable under certain conditions.
4. Application Process
Applications are filed with the Danish Patent and Trademark Office (DKPTO).
Required documentation includes a detailed description, claims, abstract, and drawings (if applicable).
The patent application undergoes formal and substantive examination.
Denmark operates a first-to-file system.
5. Patent Duration and Renewal
Patent protection lasts 20 years from the filing date.
Annual fees must be paid to maintain the patent, usually starting after the third year.
Failure to pay maintenance fees results in lapse of patent rights.
6. European Patent and International Treaties
Denmark is a member of the European Patent Organisation (EPO).
European patents can be validated in Denmark and have the same legal effect as national patents.
Denmark is a member of the Patent Cooperation Treaty (PCT), enabling international patent applications.
It also adheres to the Paris Convention for priority rights.

Patent holders have exclusive rights to prevent unauthorized use, manufacture, or sale of the patented invention.
Enforcement is through Danish courts.
Remedies include injunctions, damages, and destruction of infringing products.
