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. Lithuania transposed the Directive through a series of amendments to existing legislation in 2018, as well as with Law No XIII-1125 on the Legal Protection of Trade Secrets of the Republic of Lithuania.

It is reported that passive sharing is mandated in Lithuania, and it is practised in the mobile sector based on commercial agreements. In addition, Art. 3.2 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.

It is reported that AB Lietuvos radijo ir televizijos centras (Broadcasting of radio and television programs) is a wholly state-owned company.

It is reported that Lithuania does not mandate functional separation for operators with significant market power (SMP) in the telecom market. However, accounting separation is required by law.

It is reported that the Communications Regulatory Authority of the Republic of Lithuania (CRA), the executive authority for the supervision and administration of services in the telecommunications sector, is independent from the government in the decision-making process.

On 22 March 2022, the Lithuanian government approved a list of "hostile countries," which now face exclusion from public procurement opportunities in Lithuania. This list includes Russia, Belarus, Crimea, Transnistria, Abkhazia, and South Ossetia. As a result, companies from these countries will no longer be able to participate in public procurement processes, and existing contracts with suppliers from these regions will be terminated. The establishment of this list follows amendments to Lithuania's procurement laws, which allow national authorities to reject tenders from suppliers connected to countries deemed hostile to Lithuania, particularly in cases of mobilisation, war, or a state of emergency.

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 Lithuania, the Directive has been transposed through Appendix 2 and the Annex to Law No. I-1491 on Public Procurement and the insertion of Art. 18-1 in the Law.

It is reported that the lack of transparency is a challenge for public procurement procedures in Lithuania, especially for foreign bidders, including with respect to overly narrow definitions of tenders and implicit biases in favour of local vendors and state-owned enterprises. Moreover, foreign companies have expressed concern that large projects are often split into multiple smaller tenders, which favours local companies and reduces economies of scale for foreign bidders.

According to the Law on Investment, which establishes the terms and conditions of investment in the Republic of Lithuania, the rights of investors and investment protection measures for all types of investment (Art. 1), there are no prohibited sectors for investment and no limits of control by foreigners. In addition, foreign investors are reported to have the right to repatriate profits, income or dividends, in cash or otherwise, or to reinvest them without limitation upon payment of taxes. The law does not establish limits on foreign ownership or control. Foreign investors have free access to all sectors of the economy, with some limited exceptions in sectors related to the security and defence of the State.

Lithuania applies screening for foreign investments in certain economic sectors important to national security under Arts. 2.4 and 6 of the Law on Protection of Objects Important to Ensuring National Security of the Republic of Lithuania, No. IX-1132. Economic sectors deemed important to national security include information technologies, telecommunications, and other high-tech technologies. While screening in these sectors is not mandatory, the procedure may be started at any stage (including ex-post investment) at the initiative of the entities responsible for the protection of national security, such as the Government, Minister, Bank of Lithuania and other institutions laid down in the Law. When an investor acquires ownership of more than one-quarter of the entity of the strategic sector, this acquisition must be notified to the Commission on Coordination of Security for Objects of Importance for National Security. However, as of 2022, no cases of investment blocking in sectors relevant for digital trade are known to have occurred in Lithuania.

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