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.

In short

知识产权证书不是版权登记——它是创作在先的密码学证明。了解Swiss Trust Layer颁发的内容、其在法庭上证明的事项，以及为何风险投资人在尽职调查中提出这一要求。

2026年2月，一家苏黎世医疗科技初创公司的A轮融资领投方发来了一份知识产权尽职调查清单。第七条写道：提供所有核心算法的知识产权证书。首席技术官拥有Git提交记录、Slack讨论串和一个记录了18个月开发历程的共享Notion看板。这些材料都无法回答投资方的问题。投资方律师需要来自独立第三方的证明，证明创始团队在竞争对手优先权日期之前，以当前形式创建了这些算法。创始团队无法给出答案。

"知识产权证书"这一术语在初创公司对话和投资者条款清单中广泛流传，却鲜少被精确定义。创始人在不清楚它究竟是什么的情况下便提出申请。知识产权律师根据执业司法管辖区给出不同的定义。投资者在尽职调查清单中提及它，却不说明期望的标准。本指南定义了知识产权证书的本质，解释了Swiss Trust Layer的合格电子印章所认证的内容，并阐述了法院和机构投资者将某些证书视为有意义证据的具体原因。
