It is reported that the Danish government actively encourages foreign investment based on the principle of national treatment and that there are no limits on foreign ownership.

The Investment Screening Act covers foreign direct investments in Denmark. According to Art. 5 of the Act, foreign investors must apply for authorisation from the Danish Business Authority if they intend to directly or indirectly acquire at least 10% of the shareholdings or voting rights in a company or entity domiciled in Denmark, and the Danish company or entity belongs to particularly sensitive sectors in relation to national security or public order. Under Art. 6 of the Act, particularly sensitive sectors and activities in relation to national security or public order include companies involved in IT security functions, publicly accessible electronic communications networks and services, central data storage, satellite, radio and television transmission, central public digital identification, common public master data, including geodata, personal registration and central business registration, as well as critical technology, such as artificial intelligence for autonomous vessels and machine learning for biometric identification.
Pursuant to Art. 14, the Danish Business Authority may carry out further investigation if an investment has been made without authorisation in violation of the Act. The Authority can then either order the violation to be brought to an end, i.e. authorisation must be applied for within a specified period, or the investment must be stopped by a given date. Notification is voluntary for investments in other sectors that will achieve at least 25% of the shareholding or voting rights or equivalent controls by other means and where the investment may pose a threat to national security or public order (Art. 10).

Pursuant to Art. 11 of the Consolidate Patents Act (2019), the Patent and Trademark Office may invite the applicant to appoint a patent agent residing in the European Economic Area (EEA) to represent the applicant in all matters relating to the application. Moreover, it is reported that it is strongly recommended that foreign applicants prosecute the patent in Denmark through a local agent, a Danish registered patent attorney.

Denmark is a party to the Patent Cooperation Treaty (PCT).

There is no general principle for the use of copyright-protected material comparable to the fair use/fair dealing principles. Directive 2001/29/EC defines an optional but exhaustive set of limitations from the author´s exclusive rights under the control of the “three-step test” in line with the Berne Convention that establishes three cumulative conditions to the limitations and exceptions of a copyright holder’s rights. The Directive has been transposed by Member States with significant freedom.
In general, the Danish copyright regulation corresponds to the scope of exceptions and limitations set out in the Copyright Directive. Accordingly, the three-step test originating in the Berne Convention applies to all the provided exceptions and limitations. Chapter 2 of the Danish Consolidate Act on Copyright contains a comprehensive list of copyright exceptions.

The European Union and Denmark have adopted the World Intellectual Property Organization (WIPO) Copyright Treaty. The treaty was ratified on 14 December 2009 and came into effect on 14 March 2010.

The Danish Public Procurement Act (part 1, section 3) states that a contracting authority shall treat economic operators or services from member states of the European Union or the European Economic Area equally to Danish economic operators and services. Economic operators and services from other countries shall also be treated equally to Danish operators, to the extent that this follows from international obligations incumbent on Denmark or the European Union.

Art. 85 of the Utilities Directive (2014/25/EU) contains provisions allowing contracting public entities to reject foreign goods not covered by any EU international commitments from its tender procedures. In these cases, a tender submitted for the award of a supply contract may be rejected where the proportion of the products originating in third countries exceeds 50% of the total value of the products constituting the tender (Art. 85.2). Additionally, in cases of equivalent offers, the provisions provide for a preference for European tenders and tenders covered by EU's international obligations. In practice, this possibility has rarely been used.
Although the Danish Public Procurement Act has not directly included Art. 85 of the Utilities Directive (2014/25/EU), it states that contracting entities shall comply with the provisions of the Utilities Directive.

The Consumer Rights Directive 2011/83/EU provides an updated framework aimed at encouraging online sales. The Directive has been implemented through an amendment of the Consumer Protection Act.

The Directive 2000/31/EC (E-Commerce Directive) is the legal basis governing the liability of Internet Services Providers (ISPs) in the EU Member States and includes a conditional safe harbour. Not all Member States have transposed the relevant articles consistently, leading to divergent national case law that could cause legal insecurity on an EU level.
The Act on Some Services of Information implements the e-Commerce Directive into Czech law incorporating mere conduit (§ 3), caching (§ 4) and hosting safe harbours (§ 5), and prohibition of general monitoring obligation (§ 6).
