Open source software (OSS) has long been the backbone of modern software development and digital infrastructure. Companies, start-ups and public authorities naturally build on frameworks, libraries and system components whose source code is publicly accessible. However, this technical freedom is accompanied by a legal responsibility that is often underestimated. Anyone who uses open source – whether for internal development or in commercial products – enters a complex field of copyright, licensing law and contract design.

The following is an overview of the most important legal aspects of open source software in Germany – with the aim of giving decision-makers and developers guidance and avoiding typical risks. I have been writing on this topic myself for decades.

The vision of using 3D printers on the Moon has gained significant momentum in recent years. What seemed like a chapter from a science fiction novel not long ago is now coming within reach. Advances in additive manufacturing and successful tests of this technology in space reveal the immense potential that 3D printing holds for space exploration. However, where there are opportunities, there are also threats—especially in the realm of cybersecurity. Protecting sensitive print data and ensuring the integrity of the printing processes are crucial to realizing the vision of an autonomous Moon base supported by 3D printing.

Freedom of expression is a cornerstone of democracy and is enshrined in Article 5 of the German Basic Law. It guarantees everyone the right to freely express and disseminate their opinions in speech, writing and images. At the same time, it includes freedom of information, freedom of the press and freedom of reporting through radio and film. However, this fundamental right is not absolute – it is limited by general laws, the protection of minors and the protection of personal honor. The balance between freedom and protection is essential for social coexistence and the rule of law.

As a lawyer, I would like to explain to interested foreign readers what freedom of expression in Germany is all about, especially after the shocking and in some cases embarrassing speech by the US Vice President JD Vance in Munich 2025.

Loot boxes, virtual loot boxes in video games, have attracted considerable attention in recent years. They offer players randomly generated virtual items that can range from purely cosmetic changes to game-changing advantages. The legal assessment of loot boxes is complex and concerns both gambling law and the protection of minors and consumers. This article provides a brief overview for providers and users.

A ruling by the Higher Regional Court of Frankfurt (case reference: 10 U 201/22) on December 19, 2024 dealt with a central conflict in IT services: the distinction between a contract for work and a contract for services. It concerned the development of interfaces within a larger software project and the question of whether the provider is liable for a specific success or merely for diligent action. This decision is of considerable relevance for companies as it provides guidelines for the drafting of contracts and legal protection for software projects.
