What is Swiss IP Protection?

Intellectual property covers all creations of the human mind: literature, art, music, architecture, software, inventions, and trade secrets. In Switzerland, this protection is governed by the Copyright Act (URG, SR 231.1) and specific laws for patents, trademarks, and designs.

The problem in the digital world: files can be copied, modified and distributed without clearly proving when they were originally created or who created them. Cryptographic sealing solves this.

Swiss Trust Layer uses the Federal Act on Certification Services in the Area of Electronic Signatures (ZertES, SR 943.03) to give your documents an immutable, legally binding timestamp. This digital timestamp serves as court-admissible proof of ownership: it proves who was the creator of a work at what point in time.

Unlike simply storing in the cloud or emailing yourself, both legally contestable, a ZertES seal is cryptographically bound and certified by an accredited Swiss Trust Service Provider. It cannot be backdated or falsified.

Who needs Swiss IP Protection?

Legally secure IP protection is not only relevant for large corporations. Every person who creates intellectual property benefits from cryptographic sealing.

Architects & Engineers

Protect BIM models, blueprints, and design concepts from unauthorised use. A cryptographic timestamp proves your design existed at a specific moment, essential in copyright disputes.

Musicians & Composers

Seal compositions, lyrics, and production files before sharing with labels or collaborators. The seal serves as irrefutable proof of ownership.

Startups & Founders

Secure pitch decks, algorithms, and business concepts during development. Show investors that your IP is legally documented.

Lawyers & Legal Professionals

Sign contracts, mandate agreements, and briefs with a qualified electronic signature under ZertES SR 943.03, court-admissible and evidentially valid.

Healthcare & Medical

Seal patient records, research data, and clinical protocols in a GDPR-compliant and audit-proof manner. Cryptographic proof prevents subsequent tampering.

How does sealing work?

Three simple steps to a legally secure document, no technical knowledge, no software installation.

Upload your document

Upload your file to the Swiss Trust Layer platform. Supports PDF, DOCX, ZIP, CAD, Audio, Video, and all common formats, up to 500 MB per file.

Cryptographic sealing

The platform applies a qualified electronic signature under ZertES SR 943.03 within seconds. An immutable cryptographic timestamp is linked to your document.

Receive your certificate

You receive a sealing certificate with timestamp, hash value, and signature proof. This certificate can be publicly verified at any time, no login required.

Sealing in under 2 minutes

From file upload to finished certificate, the entire process takes under 2 minutes. Cryptographic computation and signing is done entirely on secure Swiss infrastructure.

Legal basis: what protects your seal?

The legal basis of the protection rests on three complementary legal frameworks that together provide comprehensive and internationally recognised protection.

ZertES SR 943.03: Swiss Federal Act

The Federal Act on Certification Services (ZertES, SR 943.03) governs the issuance and recognition of qualified electronic signatures in Switzerland. Under ZertES Art. 2, a qualified electronic signature is legally equivalent to a handwritten signature. Swiss Trust Layer uses Swisscom Trust Services as an accredited QTSP. ZertES →

eIDAS (EU Regulation No 910/2014): European framework

For business relationships within the EU, eIDAS applies as a parallel legal framework. Swisscom Trust Services holds both a ZertES accreditation and an eIDAS QTSP certification, meaning a Swiss Trust Layer seal is legally recognised in Switzerland and all 27 EU member states. eIDAS →

Berne Convention: International reach

The Berne Convention for the Protection of Literary and Artistic Works (1886) obliges all 181 signatory states to recognise each other's copyrights. A cryptographically sealed document with timestamp is accepted as proof of ownership in any of these countries, without separate registration.

Important note: Swiss Trust Layer provides technical sealing services. This page offers general information on legal frameworks but does not replace individual legal advice. For specific legal questions, we recommend consulting a specialist in Swiss intellectual property law.

Frequently asked questions

Answers to the most important questions about Swiss IP protection and cryptographic sealing.

What is a ZertES seal?
A ZertES seal is a qualified electronic signature under Swiss Federal Act SR 943.03. It has the same legal standing as a handwritten signature before Swiss courts and is issued by an accredited Qualified Trust Service Provider (QTSP) such as Swisscom Trust Services.

Yes. Under ZertES Art. 2, a qualified electronic signature from an accredited Swiss QTSP is legally equivalent to a handwritten signature. Sealed documents are accepted by Swiss courts, notaries, and authorities as legally valid documents.
How long does sealing take?
Sealing takes less than 2 minutes. You upload your document, and the platform immediately applies a cryptographic timestamp. The sealed document with certificate is then available for download.
Which file formats are supported?
Swiss Trust Layer supports all common digital formats: PDF, DOCX, ZIP, CAD files, audio, video, and others. Any digital file can be sealed and given a cryptographic timestamp.
