How can software startups in Switzerland protect their IP?

Swiss software startups have multiple IP protection strategies: (1) Copyright: source code is automatically protected from creation under Swiss URG and the Berne Convention; apply qualified electronic timestamps to each major release to document creation dates; (2) Trade secrets: proprietary algorithms, data processing methods, and business logic kept confidential under Swiss UWG (Unfair Competition Act) and Criminal Code Art. 162; (3) Patents: the European Patent Office (EPO) covers Switzerland; software patents face strict requirements (must have 'technical character') but system and method patents are often viable for software-implemented innovations; (4) Trademarks: register brand names and logos with IGE/IPI (Switzerland) for domestic protection; (5) Contractual protection: NDAs, IP assignment agreements, and licence agreements. Qualified electronic timestamps are the lowest-cost, most immediate protection for code.

Does Switzerland allow software patents?

Switzerland follows European Patent Office (EPO) practice via the European Patent Convention (EPC). The EPO does not grant patents for software 'as such' (EPC Art. 52(2)(c)), but software-implemented inventions with 'technical character', producing a technical effect beyond the normal physical interactions between software and hardware, can be patented. In practice, this means algorithm patents are difficult, but system-level innovations (network protocols, hardware-software integration, performance improvements measured in technical terms) can be patentable. For pure business method software, patents are typically unavailable in Europe. Swiss startups should consult a European Patent Attorney (EPA) to assess patentability; copyright and trade secret protection cover the code itself regardless of patentability.

How do qualified electronic timestamps protect startup source code?

A qualified electronic timestamp on a source code repository snapshot or release archive creates a legal presumption under eIDAS Art. 41(2) that the code existed in its exact form at the recorded date. This establishes: (1) Priority of creation: if a competitor claims to have created the same functionality first, your earlier qualified timestamp proves your code existed first; (2) Copyright creation date: copyright protection exists from creation; the timestamp documents when specific code was written; (3) Trade secret existence: if your algorithm is challenged as not being a trade secret, the timestamp proves when the confidential code existed and was subject to secrecy measures; (4) Employee departure disputes: timestamps on code versions before an employee's departure date prevent claims that they contributed code after leaving. Integration with CI/CD pipelines allows automatic timestamping on every release.

What IP assignments must Swiss startups execute before raising investment?

Before raising investment, Swiss startups must execute: (1) Founder IP assignments: formal written assignments from each founder transferring all IP created before and during their work for the company to the company entity; (2) Employee IP assignment clauses: included in employment contracts, ensuring all work-for-hire IP is automatically assigned to the company; (3) Contractor IP assignments: specific written agreements with any freelancers, consultants, or development firms who contributed to the product; (4) IP transfer from predecessor entities: if any IP was developed in a previous company or structure. Each assignment must be dated, signed (qualified electronic signatures are legally binding in Switzerland under ZertES), and ideally timestamped. Gaps in this chain are the most common IP due diligence failure point for Swiss startups.

How should Swiss software startups document trade secrets?

Documenting trade secrets in Switzerland requires: (1) Identify and list trade secrets: create a confidential trade secret register listing each proprietary algorithm, method, dataset, or know-how; (2) Implement access controls: restrict access to trade secrets to need-to-know personnel, log access; (3) Execute NDAs: with all employees, contractors, and partners who have access; (4) Mark documents as confidential: use explicit confidentiality labels; (5) Apply qualified electronic timestamps to the trade secret register and key technical documentation, proving when specific trade secrets were created and in what form, under ZertES SR 943.03 standards; (6) Conduct regular audits. The Swiss UWG (Unfair Competition Act) and Criminal Code Art. 162 protect trade secrets only if reasonable steps were taken to maintain secrecy. Documentation and timestamping are the evidence that these steps existed.

En avril 2024, les deux cofondateurs d'une société B2B SaaS genevoise se sont séparés à la suite d'une rupture de leur relation de travail. En moins de trois semaines, le cofondateur partant a revendiqué la propriété du module d'authentification qu'il avait développé lors de la première année de la société. Le fondateur restant disposait d'un historique de commits git. Le cofondateur partant disposait du même historique avec son nom sur les mêmes commits. Aucun horodatage externe n'existait sur le code central. Le différend a été soumis à la médiation. Les frais juridiques ont dépassé 180 000 CHF avant qu'un accord soit conclu.

Ce résultat n'est pas exceptionnel. Les startups suisses dans le domaine des logiciels évoluent dans l'un des environnements commerciaux les plus sensibles en matière de propriété intellectuelle au monde. La solide tradition juridique de la Suisse, sa proximité avec les marchés européens et son secteur actif de capital-risque font que la qualité de la documentation de la PI influe directement sur les valorisations lors des levées de fonds, les négociations de partenariats et les multiples de sortie.
