Restrictive Open Source License Template for the Netherlands

A Restrictive Open Source License allows you to share your software code publicly while maintaining specific controls over how others can use, modify, and distribute it. Unlike permissive open source licenses that grant broad freedoms, this restrictive approach enables you to protect certain commercial interests or limit specific applications while still embracing open source principles. Under Netherlands law, this license type provides a balanced framework governed by the Dutch Civil Code and EU Software Directive.

When do you need this document?

You need a Restrictive Open Source License when standard open source licenses are too permissive for your business needs, but a fully proprietary license would limit beneficial community engagement. This is particularly relevant if you're developing software with commercial value that you want to share for educational, research, or non-commercial purposes while preventing competitors from freely using your work. Companies often use this approach for core technologies, specialized algorithms, or software tools where they want to encourage innovation and collaboration while maintaining competitive advantages. It's also suitable when you need to comply with specific industry regulations or want to restrict usage in certain geographic regions or market sectors.

Key legal considerations

The restrictions you include must comply with EU Competition Law to avoid anti-competitive practices under Articles 101 and 102 TFEU. Your license terms should clearly define what constitutes commercial use, derivative works, and permitted modifications to prevent disputes. Consider how your restrictions interact with the EU Software Directive's provisions on reverse engineering and interoperability, as overly broad restrictions might be unenforceable. If your software processes personal data, ensure your license terms align with GDPR requirements regarding data handling responsibilities. The grant of rights section must be specific enough to provide legal certainty while avoiding restrictions that could be deemed unreasonable under Dutch contract law principles.

Legal requirements in Netherlands

Under Dutch Civil Code provisions, your license must meet standard contract formation requirements, including clear offer, acceptance, and consideration terms. The Dutch Copyright Act (Auteurswet) governs the underlying intellectual property rights, so ensure your license doesn't contradict statutory copyright protections or mandatory author's rights. Your restrictions must be proportionate and justified by legitimate business interests to withstand legal challenge under Dutch contract interpretation principles. The Database Directive may apply if your software includes substantial database components, requiring additional consideration of database rights. All license terms must be drafted in clear, unambiguous language as required by Dutch consumer protection laws, even though this primarily applies to business-to-business licensing arrangements.
