The Directive 2016/943 on the protection of undisclosed know-how and business information (trade secrets) is key in harmonising national laws concerning trade secrets. Slovenia implemented the Directive through an act amending the Civil Procedure Act in 2017 and the Professional Secrecy Act of 2019.

It is reported that passive sharing is mandated and is effective in both the mobile (based on commercial agreements) and fixed sectors. In addition, Art. 3.2 of the Directive 2014/61/EU establishes that Member States shall ensure that, upon written request of an undertaking providing or authorised to provide public communications networks, any network operator must meet all reasonable requests for access to its physical infrastructure under fair and reasonable terms and conditions, including price, with a view to deploying elements of high-speed electronic communications networks. Such written request shall specify the elements of the project for which the access is requested, including a specific time frame.

The government of Slovenia owns 62.54% of Telekom Slovenije, the major incumbent telecommunications operator. State-owned entities Kapitalska druzba (KAD) and Slovenian Sovereign Holding (SDH) respectively hold a further 5.59% and 4.25% in Telekom Slovenije.

It is reported that Slovenia does not mandate functional separation for operators with significant market power in the telecom sector. However, accounting separation is required in certain cases. According to Art. 25 of the Electronic Communications Act, the Agency may impose an obligation on a specific network operator with significant market power to keep accounting records in relation to specified activities relating to interconnection and/or operator access separate from accounting records for other activities.

It is reported that the Agency for Communication Networks and Services of the Republic of Slovenia (AKOS), the executive authority for the supervision and administration of services in the telecommunications sector, is independent from the government in the decision-making process.

Arts. 23.1 and 23.4 of the ZVOP-2 stipulate that personal data specified in legislation governing administrative internal affairs, financial administration, citizenship, the Slovenian Intelligence and Security Agency, defence, healthcare, compulsory health insurance, the exercise of rights arising from public funds, and criminal and misdemeanour records, must not be stored outside the territory of Slovenia.

The Investment Promotion Act, as amended by the Act on Amendments and Additions to the Investment Promotion Act (Slovenian FDI Control Rules), supersedes the temporary FDI framework previously established under the Act defining intervention measures to mitigate and address the impacts of the COVID-19 pandemic (Official Gazette of the Republic of Slovenia, No. 80/20). Under the revised Art. 31 of the Investment Promotion Act, foreign acquisitions in "critical sectors" that meet specific criteria are required to be notified to and reviewed by a Notification Commission established by the Ministry of the Economy, Tourism, and Sport. These criteria include: (i) direct or indirect acquisitions of at least 10% of the share capital or voting rights of a corporate entity registered in Slovenia, and (ii) investments in tangible or intangible assets for the establishment of a new corporate entity in Slovenia, where the foreign investor acquires, directly or indirectly, at least 10% of the share capital or voting rights of the newly established entity.
Art. 31.c of the law specifies that sectors and activities of special focus include: (i) critical physical or virtual infrastructure, such as communications, media, and data processing or storage; (ii) critical technologies and dual-use products, including artificial intelligence, semiconductors, and cybersecurity; and (iii) information and communications technology.d

Although there is no discrimination against foreign companies based on the principle of reciprocity, foreign patent applicants have to act before the Slovenian Intellectual Property Office through a patent agent, and the submission of information has to be carried out in Slovenian.

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 Slovenia, the Directive has been transposed with the Public Procurement Law (ZJN-3).

Art. 7 of the Slovenian Public Procurement Act provides that mutual recognition should be taken into account to grant equal treatment in public procurement procedures. Furthermore, Art. 11 stipulates that all economic operators from third countries shall be accorded the same treatment as economic operators from the EU only for the award of a contract which is covered by the WTO Government Procurement Agreement or by another binding agreement of the European Union or the Republic of Slovenia.
