How do I prove I own IP in a copyright dispute?

To prove IP ownership in a copyright dispute: (1) Establish that the work is original and you created it: qualified electronic timestamps on your creative work establish creation date with a legal presumption under eIDAS Art. 41(2); (2) Show the chain from creator to current rights-holder: if the IP was assigned, show dated and signed IP assignment agreements (also timestamped for evidentiary value); (3) Demonstrate the defendant copied: show substantial similarity plus that the defendant had access to your work; (4) Quantify damages: registration (e.g., US Copyright Office for US claims) affects the damages available. The combination of a qualified timestamp, version history, and internal documentation creates a compelling evidential package.

What is the difference between copyright registration and a qualified electronic timestamp for IP protection?

Copyright registration (e.g., with the US Copyright Office) is a formal administrative step that creates a public record of your copyright claim and is required to sue for statutory damages in the US. However, most countries, including Switzerland and all EU member states, do not require registration; copyright arises automatically at creation under the Berne Convention Art. 5(2). A qualified electronic timestamp under eIDAS Art. 41 proves creation date without registration. It is legally presumed accurate in all EU and Swiss courts. For disputes in Europe: a qualified timestamp is legally more powerful than self-registration because it carries a rebuttable legal presumption. For US claims: US Copyright Office registration is required to sue for statutory damages; a qualified timestamp complements registration by proving the exact creation date.

Can I use email and messaging records to prove IP ownership?

Email and messaging records can support IP ownership claims as circumstantial evidence: they show the work was discussed, shared, or developed at a specific time. However, email timestamps are controlled by email servers that can be incorrect or manipulated; messaging records are stored by third-party platforms that may not preserve records indefinitely; and neither creates a legal presumption in EU or Swiss courts. A qualified electronic timestamp from an eIDAS QTSP creates a legal presumption of accuracy (Art. 41(2)). This is a different class of evidence. Best practice: keep emails and messaging records as contextual evidence, and apply qualified timestamps to the actual creative work at each milestone for the primary evidential foundation.

What should I do immediately if I discover my IP has been infringed?

Act immediately: (1) Document the infringement: screenshot the infringing content with timestamps, record the URL, note the date of discovery; (2) Apply a qualified electronic timestamp to your documentation of the infringement: proving when you became aware matters for notice periods and limitation periods; (3) Gather your ownership evidence: qualified timestamps on your original work, version history, IP assignment records; (4) Send a cease and desist letter: document this with a qualified timestamp and track delivery; (5) Contact an IP lawyer specialising in copyright: the strategy depends on jurisdiction, scale of infringement, and available remedies; (6) Do not alter or delete any records related to the dispute. In Switzerland, the 3-year limitation period (Art. 60 OR) runs from knowledge of infringement.

How do I prove IP ownership if my records are stored in cloud services?

Cloud service records (Google Drive version history, GitHub commit logs, Dropbox timestamps) are useful circumstantial evidence but are not qualified evidence: they are controlled by third-party platforms that could alter records, may not preserve them indefinitely, and do not carry a legal presumption under EU or Swiss law. To strengthen cloud-based evidence: (1) Export and apply qualified electronic timestamps to important document versions: this creates an independent, legally presumed record of the document at a specific date; (2) Maintain git commit logs with signed commits for code; (3) Keep a project diary with sequential entries, each timestamped; (4) Store a timestamped copy of your work outside the cloud platform you use for development. Cloud records corroborate; qualified timestamps establish the legal foundation.

In short

In einem Urheberrechtsstreit hängt das Ergebnis davon ab, wer das Erstellungsdatum beweisen kann. Hier erfahren Sie genau, was EU- und Schweizer Gerichte akzeptieren — und wie Sie gerichtsverwertbare Nachweise erstellen, bevor ein Streit entsteht.

Im Februar 2026 lieferte ein Genfer Branding-Studio eine vollstandige visuelle Identitat an ein SaaS-Startup ab, drei Tage bevor der Dienstleistungsvertrag gegengezeichnet wurde. Das Startup wurde vier Monate spater liquidiert. Die Liquidatoren ubertrugen alle unternehmensseitig entwickelten Schutzrechte an einen Kaufer, einschliesslich des Logodesigns des Studios. Das Studio besass Versionsdateien, Slack-Chats und eine PDF-Rechnung. Die Anwalte des Kaufers hatten eine einzige Frage: Beweisen Sie, dass das Studio die Arbeit vor dem Vertragsdatum erstellt hat. Das Studio konnte es nicht. Der Rechtsstreit kostete CHF 210.000 in einem Vergleich.

Wenn Sie in einem Urheberrechtsstreit den Nachweis des geistigen Eigentums erbringen mussen, hangt alles von einer Frage ab: Konnen Sie beweisen, wann Sie das Werk erstellt haben, und was es zu genau diesem Zeitpunkt enthielt? Dieser Leitfaden erklart, welche Beweise Gerichte in der EU und der Schweiz akzeptieren, warum digitale Zeitstempel entscheidend sind und wie Sie am schnellsten rechtlich verwertbare Schopfungsnachweise erstellen konnen.
