What is an intellectual property certificate?

An intellectual property (IP) certificate is a formal document evidencing a rights-holder's claim over a specific piece of intellectual property at a specific date. Unlike patent or trademark registration certificates (issued by government IP offices), Swiss Trust Layer's IP certificates are qualified electronic timestamp certificates. They prove that specific creative work, invention description, or IP documentation existed in its exact form at a recorded date. Each certificate is backed by a qualified electronic timestamp from a QTSP on the EU Trusted List, carrying a legal presumption under eIDAS Art. 41(2) in all EU member states and Switzerland. IP certificates are used by creators, startups, law firms, and enterprises to establish IP creation timelines without the cost and complexity of patent filing.

Is an IP certificate from Swiss Trust Layer legally recognised?

Swiss Trust Layer's IP certificate is a qualified electronic timestamp certificate issued through a QTSP on the EU Trusted List. The certificate itself, a sealed PDF containing the timestamp data and cryptographic hash, is legally valid evidence in all 27 EU member states and Switzerland. The underlying qualified electronic timestamp carries a legal presumption under eIDAS Art. 41(2) that the document existed in its exact form at the recorded date. This presumption applies in civil and commercial court proceedings. The certificate is not a registered patent or copyright registration. It proves creation date, not a registered monopoly right. For copyright (where no registration is required under Berne), an IP certificate is often the most appropriate and cost-effective form of IP protection.

What can I seal to get an IP certificate?

Any digital file can be sealed to obtain an IP certificate: creative works (manuscripts, screenplays, musical compositions, source code, design files), invention disclosures and technical specifications, business plans and pitch decks, trade secret documentation, scientific research and datasets, contracts and legal agreements, architecture and engineering drawings. The platform computes a cryptographic hash of the uploaded file. The hash, not the file, is sent to the QTSP for timestamping. Your file remains entirely private. You receive an IP certificate containing the timestamp, the file hash, your identifier, and the QTSP's digital seal. Anyone can verify the certificate against the original file using Swiss Trust Layer's public verification page.

How is an IP certificate different from a copyright registration?

A copyright registration (available in some countries like the US through the Copyright Office) is an administrative filing creating a public record of your copyright claim, required to sue for statutory damages in the US but not in the EU or Switzerland. An IP certificate (qualified electronic timestamp) proves creation date with a legal presumption. It establishes when your work was created. Copyright arises automatically in all Berne Convention countries (175+ member states) without registration; the IP certificate documents the date of creation. For EU and Swiss disputes: the IP certificate is typically more legally powerful than a simple self-declaration because it carries a legal presumption. For US disputes: an IP certificate complements Copyright Office registration by proving exact creation date, which affects damages calculations and priority.

How long is an IP certificate valid?

An IP certificate's cryptographic proof is permanent. The hash and timestamp embed together cryptographically, creating permanent record of the document's state at the timestamp date. The certificate's legal validity under eIDAS is not time-limited. Art. 41's legal presumption applies whenever the certificate is presented as evidence. To protect against future changes in cryptographic standards, Swiss Trust Layer applies PAdES long-term validation (LTV) profiles (ETSI EN 319 132), embedding all verification material at the time of issuance so the certificate can be verified even decades later. The content you sealed is copyrighted for the life of the author plus 70 years (Berne Convention); the IP certificate serves as evidence for the full copyright term.

Geistiges Eigentum Zertifikat: Was es beweist und warum Investoren und Gerichte es verlangen

Ein IP-Zertifikat ist keine Urheberrechtsregistrierung — es ist ein kryptografischer Beweis für vorheriges Schaffen. Hier erfahren Sie, was Swiss Trust Layer ausstellt, was es vor Gericht beweist und warum VCs es bei der Due Diligence fordern.

Im Februar 2026 schickte der Series-A-Investor eines Zuercher Medtech-Startups eine IP-Due-Diligence-Checkliste. Punkt sieben lautete: IP-Zertifikate fuer alle Kernalgorithmen vorlegen. Der CTO hatte Git-Commits, Slack-Threads und ein gemeinsames Notion-Board, das 18 Monate Entwicklung dokumentierte. Keine dieser Unterlagen beantwortete die Frage des Investors. Der Anwalt des Investors wollte den Nachweis von einem unabhaengigen Dritten, dass das Gruenderteam diese Algorithmen in dieser Form vor dem Prioritaetsdatum des Wettbewerbers entwickelt hatte. Das Team hatte keine Antwort.

Der Begriff "geistiges Eigentumszeugnis" kursiert haeufig in Startup-Gespraechen und Investitions-Term-Sheets, wird aber selten praezise definiert. Gruender fragen danach, ohne genau zu wissen, was es ist. IP-Anwaelte geben unterschiedliche Definitionen, je nach ihrer Rechtsordnung. Investoren erwaehnen es in Due-Diligence-Checklisten, ohne den erwarteten Standard anzugeben. Dieser Leitfaden definiert, was ein IP-Zertifikat ist und was nicht, erklaert, was Swiss Trust Layers World Court Proof e-Seal zertifiziert, und legt die konkreten Gruende dar, warum Gerichte und institutionelle Investoren bestimmte Zertifikate als bedeutsame Beweise behandeln.
