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.
In Luxembourg, the Directive has been transposed with Art. 147 of the Law on Public Procurement.

Art. 62 of the Law on Public Procurement states that the contracting authorities shall grant public procurement participants of countries with which Luxembourg or the EU has international commitments (through the Government Procurement Agreement and other international conventions) treatment no less favourable than that accorded to participants from the European Union. Thus, equal treatment is not granted to operators from other countries.

It is reported that there are no specific restrictions on foreign ownership or control and no sectoral limitations. The country conducts a general review of foreign investments, similar to that applied to domestic investments.

The Luxembourg Act of 14 July 2023, which establishes a new foreign direct investment (FDI) regime, applies to investments in critical sectors such as telecommunications, data processing/storage, and media (Art. 2) by investors from outside the European Economic Area (foreign investors). These investments allow foreign investors to exercise direct or indirect control over entities established under Luxembourg law. According to Art. 3, any investment subject to this FDI regime must be notified to the Ministry of the Economy and receive authorisation before implementation.
Control is considered acquired when a foreign investor meets any of the following thresholds: holding 25% of the voting rights in the Luxembourg entity; holding a majority of the voting rights of shareholders or partners, with multiple notifications required for multi-stage acquisitions; having the right to appoint or remove the majority of board members while being a shareholder or partner; or controlling a majority of voting rights through agreements with other shareholders or partners.
The FDI Law also classifies as critical any research, production, or supplementary activities that could provide access to sensitive information or locations directly related to these sectors.

Art. 83 of the Law of July 20, 1992, on the Changes in the System for Patents for Invention (so-called Patent Act), establishes a local representation requirement for applicants without domicile or headquarters in the territory of the European Union.

Luxembourg 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.
The Law on Copyright, Related Rights and Databases implements the EU copyright directive. Section 2 provides for a closed list of exceptions to the author’s copyrights under certain conditions. These exceptions include education purposes, private use, caching, press information and parody.

The European Union and Luxembourg 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.

According to Art. 27 of the Rules on the Registration of VAT payers, foreign persons established outside the territory of the European Union must register for VAT through a branch in Lithuania or, if they have several branches, through one of them.

The EU Directive on Audiovisual Media Services (AVMS) covers traditional broadcasting services as well as audiovisual media services provided on-demand, including via the Internet. Art. 13.1 provides for Member States to secure a minimum 30% share of European works in the catalogues as well as "ensuring prominence" of those works. "Prominence" involves promoting European works by facilitating access to such works using any appropriate means to ensure their prominence. The Directive has been implemented by Member States in different ways, ranging from very extensive and detailed measures to a mere reference to the general obligation to promote European works.
In Lithuania, the EU Directive was transposed into domestic law through the amendment of the Law on the Provision of Information to the Public of the Republic of Lithuania of January 2021 (Law No. 2021-01352). According to Art. 37.6 of the Law, suppliers of on-demand audiovisual media services shall ensure that not less than 30% of programmes in the on-demand audiovisual media services listing are European works. This requirement shall not apply to on-demand audiovisual media service providers whose total annual turnover, including their own turnover and that of their affiliated undertakings, is low (less than 1% of total revenue from the Lithuanian audiovisual services market) or whose audience is small (the proportion of the audience of the on-demand audiovisual media service in Lithuania is less than 1%). Additionally, Lithuania has not implemented financial contribution obligations for VOD service providers.
