How do you prove you created something first?

The most reliable method is a qualified electronic timestamp from a QTSP listed on the EU Trusted List. Under eIDAS Art. 41(2), a qualified timestamp carries a legal presumption of accurate time and data integrity. It is generated by an independent trusted authority and cannot be altered without invalidating the timestamp. Self-generated evidence such as file metadata, email timestamps, and social media posts does not carry this presumption.

Is a file timestamp enough to prove creation date?

No. File system timestamps can be changed by anyone with filesystem access. Courts treat file metadata as unreliable standalone evidence of creation date. An email to yourself or a social media post creates a platform timestamp, but these are secondary evidence. A qualified electronic timestamp from an accredited QTSP is the legally reliable standard.

What is a qualified electronic timestamp?

A qualified electronic timestamp is a trust service from a QTSP listed on the EU Trusted List. Under eIDAS Art. 41(2), it carries a legal presumption that the date and time indicated are accurate and that the data has not been altered. The timestamp is generated using a trusted time source (RFC 3161) and cryptographically bound to a hash of the document. Swiss Trust Layer applies a qualified timestamp at sealing, starting at CHF 5 per document.

Does copyright registration prove creation date?

Switzerland and most EU countries do not have copyright registration systems, as copyright arises automatically under the Berne Convention. Where registration exists (such as in the US), a registration certificate provides evidence of the registration date, not necessarily the creation date. A qualified electronic timestamp is a more direct method of proving creation date.

What level of evidence do courts require for creation date?

In Swiss and EU civil proceedings, courts require independent evidence from a source that cannot have been manipulated by the claimant. A qualified electronic timestamp from an EUTL-listed QTSP satisfies this requirement: the QTSP is an accredited authority, and the timestamp is cryptographically bound to the document content, making retroactive alteration detectable.

How to Prove You Created Something First

Copyright arises at creation. But in a dispute, the burden is on you to prove when you created it. Here are the methods that hold up in court under Swiss and EU law, and the ones that don't.

Under the Berne Convention, copyright arises automatically at the moment of creation. No registration, no formality required. But this automatic right creates a practical problem: there is no public record of when you created something. When a dispute arises, the burden falls on you to prove creation date, and the methods you used to document that date determine whether your claim holds up in court.

Methods That Do Not Hold Up

File system timestamps: The "created" and "modified" dates on your hard drive can be changed by anyone with filesystem access. Courts routinely discount file metadata as standalone evidence.
Email to yourself: Email headers can be spoofed and content is not independently verified by any trusted third party. Secondary evidence at best.
Social media posting: Platform timestamps are controlled by the platform, can be altered through platform errors, and provide circumstantial evidence, not proof.

Methods That Hold Up in Court

1. Qualified Electronic Timestamp (eIDAS Art. 41)

Under eIDAS Art. 41(2), a qualified electronic timestamp has a legal presumption of the accuracy of the date and time it indicates and the integrity of the data to which it is bound. The timestamp is generated by a QTSP listed on the EU Trusted List, synchronized to a trusted time source under RFC 3161, and cryptographically bound to a hash of the document. No one can alter the document content without invalidating the timestamp.

Swiss Trust Layer applies a qualified electronic timestamp at the moment of sealing, anchored by a QTSP under RFC 3161. The signed document carries the timestamp in its PDF metadata and can be verified at validate.swisstrustlayer.com. Pricing starts at CHF 5 per document.

2. Notarial Certification

A notary can certify the date of creation by witnessing the signing of a document that includes a hash or description of the work. This is legally reliable but expensive and geographically constrained.

3. Depositing With a Collecting Society

Organizations such as SUISA (music) or ProLitteris (text and image authors) in Switzerland accept deposits of creative works with date evidence. These provide independent third-party confirmation of creation date for specific creative categories.

The Practical Standard for IP Disputes

In Swiss and EU IP disputes, courts look for independent evidence from a trusted third party that cannot have been manipulated by the claimant. A qualified electronic timestamp from an EUTL-listed QTSP satisfies this standard. Self-generated evidence does not.

Step-by-Step: How to Create Verifiable Proof

Upload your document to Swiss Trust Layer at swisstrustlayer.com.
Apply a qualified electronic seal. The platform generates a SHA-256 hash and binds it to a trusted timestamp from an accredited QTSP under RFC 3161.
Download the sealed PDF containing the certificate chain, timestamp, and document hash.
Store the sealed document. If your creation is disputed, provide the sealed PDF and the verification URL. Any party can verify at validate.swisstrustlayer.com without an account.
