Croatia 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.
Croatia has a clear copyright exception regime, as incorporating European Union Directives relating to copyright. Such limitations are contained in Part IV
(Content limitations on copyright and related rights) of the Copyright Act, which provides, inter alia, the following exceptions:
- Temporary acts of reproduction of the copyrighted work
- Reproduction for private use
- Ephemeral recordings
- Educational and scientific institutions and libraries
- Collections intended for teaching or scientific research
- Use of copyright works for disabled persons
- Use for judicial, administrative or other official proceedings
- Use for teaching
- Use of the copyrighted works to inform the public
- Quotations
- Parodies and caricatures.

Croatia and the European Union have adopted the World Intellectual Property Organization (WIPO) Copyright Treaty. Croatia ratified the Treaty on 3 July 2000, with its provisions coming into force on 6 March 2002. Subsequently, the European Union ratified the Treaty on 14 December 2009, and it entered into effect on 14 March 2010.

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 Croatia, the Directive has been transposed with the Public Procurement Act NN 120-16.

It is reported that the extensive use of state-owned companies limits the impact of ongoing procurement reforms to promote competition for public funds and increases the risk of conflicts of interest. Moreover, despite major progress in increasing transparency, corruption remains a significant concern, considering that, for instance, some stakeholders report the existence of discriminatory technical specifications in public procurement tenders.

Croatian law prohibits any discrimination between investments on the basis of nationality. Foreign investment rules follow a reciprocity principle.

Art. 17 of the Patent Act establishes that foreign companies must act through a representative in order to register a patent with the Croatian Intellectual Property Office. In addition, a translation of the patent shall be provided in Croatian at least two months after filing.

The Consumer Rights Directive 2011/83/EU provides an updated framework aimed at encouraging online sales. The Directive has been implemented by the Chapters VI.-XII on Market Practices and Consumer Protection of the Code of Economic Law.

Belgium has not signed the United Nations (UN) Convention on the Use of Electronic Communications in International Contracts.

Belgium has not adopted national legislation based on or influenced by the United Nations Commission on International Trade Law (UNCITRAL) Model Law on Electronic Signatures.

Providers of electronic communication services have the legal obligation to identify their customers, as regulated by the Electronic Communications Act.

Art. 17 of Directive 2019/790 on Copyright in the Digital Single Market (DSM Directive) mandates that providers of content-sharing services seek authorisation from rights holders and implement technical solutions to remove and prevent unauthorised uploads by their users (so-called upload filters), under penalty of losing their liability safe harbour. Further arrangements are envisaged for complaints and dispute resolution mechanisms. Such upload filters are reported to be a significant cost for online platforms. Graduated exemptions are expected to be put in place for new providers active in the EU for less than three years with a turnover under EUR 10 million and with fewer than five million users. The provision is subject to a challenge in the Court of Justice by Poland (C-401/19)
In 2022, the Chamber of Representatives adopted the Law Transposing Directive (EU) 2019/790, therefore making online content-sharing service providers partially liable for copyright violations on their platforms.
