Poland and the European Union have adopted the World Intellectual Property Organization (WIPO) Performances and Phonograms Treaty. Poland acceded to the Treaty on 21 July 2003, with its provisions coming into force on 21 October 2003. Subsequently, the European Union ratified the Treaty on 14 December 2009, and it entered into effect on 14 March 2010.

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. Poland transposed the Directive with the Act of 5 July 2018, amending the Unfair Competition Act and certain other acts in 2018.

It is reported that passive sharing is mandated in Poland, and it is practised in the mobile and fixed sectors based on commercial agreements. In addition, Directive 2014/61/EU (Art. 3.2) 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 the government fully owns NASK (Naukowa i Akademicka Sieć Komputerowa), a Polish institution dedicated to developing and maintaining the country’s scientific and academic network infrastructure. NASK’s primary role is to provide secure and advanced network services, such as internet connectivity, high-speed networks, and cybersecurity, to research institutions, universities, and other educational organisations. It also manages domain registration and web hosting services, supporting the Polish academic and scientific community's technological needs.

Under Art. 47 of the Electronic Communications Law of 2024, telecommunications providers are required to store certain types of user data for 12 months, including user identity, date and time and the type of connection, in the territory of Poland. The Electronic Communications Act entered into force on 10 November 2024, thereby superseding the Telecommunications Act of 2004. Under Arts. 180a-180c of the repealed Telecommunications Act, telecommunications providers were required to store certain types of user data for 12 months, including user identity, date and time and the type of connection, in the territory of Poland.

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 Poland, the Directive has been transposed with the publication of the consolidated text of the Act - Public Procurement Law.

Poland promotes the establishment and ownership of business enterprises by both domestic and international entities, encouraging participation across diverse economic sectors. This framework is governed by the Entrepreneurship Act, effective since April 2018, which outlines legal provisions for business activities under the Commercial Companies Code. However, the government imposes restrictions on foreign ownership and equity investments in certain strategic sectors, including air transport, radio and television broadcasting, and airport and seaport operations. These restrictions do not apply to sectors relevant to digital trade.

Under the Act on the Control of Certain Investments, any investor from outside the European Economic Area (EEA) or the OECD intending to acquire a 20% or higher stake in a strategic Polish company requires prior approval from the President of the Office of Competition and Consumer Protection (UOKiK). The rules apply to companies with a registered seat in Poland that generate more than EUR 10 million in turnover in at least one of the two preceding financial years and that are either publicly listed, control assets classified as "critical infrastructure", develop or maintain software essential to vital processes (such as energy supply, cloud computing, healthcare, financial services, or transport and logistics), or operate in one of 21 designated strategic sectors, including telecommunications.
The regime was introduced in 2020 through Anti-Crisis Shield 4.0 (Dz.U. 2020 poz. 1086) in response to the COVID-19 pandemic. Although originally intended as a temporary measure for two years, it was subsequently extended by the Polish Parliament in mid-2022 for an additional three years, remaining in force until July 2025. In addition to the 20% acquisition threshold, filing obligations also arise when an investor’s shareholding increases beyond 40%, or in cases involving the acquisition of control or the purchase of assets constituting an enterprise or an organised part thereof. Transactions completed without the required approval are considered null and void, and violations may give rise to criminal liability, including substantial fines and possible imprisonment.
