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.

Certificato di Proprietà Intellettuale: Cosa prova e perché investitori e tribunali lo richiedono

Un certificato di PI non è una registrazione del diritto d'autore — è una prova crittografica dell'anteriorità. Ecco cosa rilascia Swiss Trust Layer, cosa prova in tribunale e perché i VC lo richiedono in due diligence.

Nel febbraio 2026, il capofila del round di Serie A di una startup medtech zurighese ha inviato una lista di controllo per la due diligence sulla proprieta intellettuale. Il punto sette recitava: fornire certificati di proprieta intellettuale per tutti gli algoritmi principali. Il CTO disponeva di commit Git, thread Slack e una bacheca Notion condivisa che documentava 18 mesi di sviluppo. Nessuno di questi materiali rispondeva alla domanda dell'investitore. Il legale dell'investitore voleva una prova da un terzo indipendente che il team fondatore avesse creato quegli algoritmi, in quella forma, prima della data di priorita del concorrente. Il team non aveva risposta.

Il termine "certificato di proprieta intellettuale" circola ampiamente nelle conversazioni tra startup e nei term sheet degli investitori, ma raramente viene definito con precisione. I fondatori ne richiedono uno senza sapere esattamente di cosa si tratta. Gli avvocati specializzati in proprieta intellettuale danno definizioni diverse a seconda della giurisdizione in cui operano. Gli investitori lo menzionano nelle liste di controllo per la due diligence senza specificare lo standard atteso. Questa guida definisce cosa e e cosa non e un certificato di PI, spiega cosa certifica il World Court Proof e-Seal di Swiss Trust Layer e illustra i motivi specifici per cui tribunali e investitori istituzionali considerano certi certificati come prove significative.
