As stipulated in Art. 24 of Law 2022:482 on Electronic Communications, as amended by the Swedish statute book (SFS) 2022:1086, any individual or entity offering an interpersonal communication service based on publicly available prepaid numbers or a prepaid Internet connection service is prohibited from providing access to the service without first registering the following details: (1) the name and postal address of the subscriber, (2) the subscriber's social security number, coordination number, organisation number, or other identification number, and (3) the number or other designation of the service. Additionally, the provider must record the time of registration, and this information must be retained and made available for up to one year after the cessation of service provision.

The Act on Responsibility for Electronic Bulletin Board requires internet sites, where users can post comments about a particular issue or topic and reply to other users' postings (i.e. bulletin boards), to monitor the service regularly and to an extent that may reasonably be required taking into account the scope and nature of the service. An intentional or grossly negligent violation of the obligation to remove illegal content is considered as a criminal offence. The Act includes an information duty (Section 3), a supervision duty (Section 4), and a duty to erase certain messages (Section 5).
This is despite Art. 15 of Directive 2000/31/EC (e-Commerce Directive) stating that Member States should not impose on providers a general obligation to monitor the information which they transmit or store, nor a general obligation actively to seek facts or circumstances indicating illegal activity.

The Protective Security Act, which was amended in 2019 to allow Swedish security and intelligence forces to recommend the revocation of operating licenses for firms in sectors important to national security if they are found to pose a security risk. The law was used in 2020 to ban Huawei and ZTE equipment from being used in the Swedish network. Specifically, the Swedish Post and Telecom Authority (PTS) has told telecommunications operators in Sweden vying for licensing rights at auction that bids including Huawei or ZTE equipment will not be considered, and pre-existing Huawei and ZTE infrastructure would need to be decommissioned by 2025. This effective ban on Huawei and ZTE equipment has been challenged in court, but so far, the decision has been upheld in the Swedish court.

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 Sweden, the EU Directive was transposed into domestic law through the amendment of the Radio and Television Act in November 2020 (SFS 2020:875). According to Chapter 5, Section 8 of the Act, providers of on-demand television must ensure that at least 30% of their catalogue consists of programmes of European origin and that these programmes are effectively promoted. Sweden has not introduced financial contribution obligations for VOD service providers.
Furthermore, under Chapter 5, Section 7, at least 10% of the annual transmission time or 10% of the programming budget must be allocated to European programmes produced by independent producers, with a significant portion of these programmes being completed within the past five years. The term "transmission time" refers to the period during which programmes are broadcast, excluding news, sports, games, announcements, teleshopping, and broadcasts consisting solely of text. Additionally, unless specific reasons prevent it, television broadcasts should include a substantial number of Swedish programmes featuring artists and creators active in Sweden.

The European Union General Data Protection Regulation (GDPR) provides a comprehensive framework for data protection that applies to all EU Member States. The GDPR was implemented in Sweden through a variety of pieces of legislation including the Act with supplementary provisions to the GDPR (SFS 2018:218) and the Ordinance with Supplementary Provisions to the GDPR (SFS 2018:219).

Under the EU Directive on Data Retention, operators were required to retain certain categories of traffic and location data (excluding the content of those communications) for a period between six months and two years and to make them available, on request, to law enforcement authorities for the purposes of investigating, detecting and prosecuting serious crime and terrorism. On 8 April 2014, the Court of Justice of the European Union declared the Directive invalid. However, not all national laws that implemented the Directive have been overturned.
In Sweden, Section 22 of Chapter 9 of the Electronic Communications Act (SFS 2022:482) stipulates minimum periods of retention for certain types of data in order to aid law enforcement. This requires, inter alia, that telecommunications operators retain internet access data for ten months, location information for two months, and call data for six months. These requirements were previously outlined in Section 16 d of Chapter 6 of the Act (2003:389) on Electronic Communication (as amended in 2019), which has been superseded by the 2022 Act.

In December 2023, the Act (2023:560) on the Screening of Foreign Direct Investments entered into force, introducing substantial changes to the regulatory framework governing foreign investments in Sweden. According to Art. 7 of the law, foreign investors engaging in sensitive sectors are mandated to secure authorisation from the reviewing authority before executing the investment. The authority holds the power to approve, conditionally approve, or prohibit the investment based on considerations related to public order or national security.
The FDI Act applies to investments in undertakings with a registered office in Sweden, including indirect transfers of shares and transfers of shares in listed companies. According to Art. 7, any prospective foreign investor in protected activities notify the inspection authority before investing if: (i) they would hold 10% or more of the votes in a relevant entity, (ii) acquire or form an entity engaging in protected activities, (iii) become a partner in a trading company conducting such activities, (iv) form a foundation engaging in these activities, or (v) gain direct or indirect influence over the management of entities or foundations involved in protected activities.
The Act covers various sectors, including essential services, security-sensitive activities (as defined in Art. 2 of the Protective Security Act), the processing of sensitive personal data or location data, the processing of sensitive personal data or location data, research or the supply of products or technology relating to emerging technologies and other strategically protected technologies.

It has been reported that patent filing fees for foreign applicants in Sweden are higher than those for domestic applicants. The Swedish Patent and Registration Office (PRV) suggests that non-residents may need to engage a local agent to file a patent. According to the Swedish Intellectual Property Office, fees for foreign patent applications range from 140 to 18,610 SEK (approximately 13 to 1,700 USD), while fees for domestic applicants range from 150 to 8,450 SEK (approximately 14 to 800 USD). Additionally, inventions made in Sweden that have implications for national security require authorisation from the Swedish patent office before they can be filed abroad.

Sweden 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 Swedish Act on Copyright in Literary and Artistic Works was amended to be consistent with the Directive, but Sweden applies copyright exceptions very narrowly, choosing not to employ the three-step test. The economic rights conferred by the Copyright Act are relaxed in cases of making physical copies for private or educational use or when an author has previously authorised the reproduction of the work in the EEA (the Consumption Principle). However, Section 12 of the Copyright Act explicitly excludes creating digital copies of copyrighted material or making copies of computer programs and software, and a 2016 ruling by the Swedish Supreme Court found that posting photos of public art online was not consistent with Swedish copyright law.

The European Union and Sweden 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 European Union and Sweden have adopted the World Intellectual Property Organization (WIPO) Performances and Phonograms Treaty. The treaty was ratified on 14 December 2009 and came 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. Sweden transposed the Directive through a series of amendments to existing legislation as well as the Trade Secrets Act of 2018.

In Sweden, the sharing of passive infrastructure is mandated to support the delivery of telecommunications services to end users. Pursuant to Sections 15 and 16 of Chapter 5 of the Electronic Communications Act, operators classified as undertakings with significant market power may be required to comply with reasonable requests for access to and use of infrastructure essential for the construction of electronic communications networks, as well as networks and associated facilities necessary for providing electronic communications services.

The Swedish government owns a 39.5% stake in Telia, one of Sweden's largest telecommunications firms. The government had full ownership of Telia up until 2006, when Telia merged with Sonera, and the Swedish government's stake fell to 46%. They have since divested further, bringing the current stake to 39.5%
