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

En una disputa de derechos de autor, el resultado depende de quién puede probar la fecha de creación. Aquí está exactamente lo que aceptan los tribunales de la UE y Suiza — y cómo construir pruebas admisibles antes de que surja una disputa.

En febrero de 2026, un estudio de diseno de marca con sede en Ginebra entrego una identidad visual completa a una startup de SaaS tres dias antes de que se contrafirmara el contrato de servicios. La startup entro en liquidacion cuatro meses despues. Los liquidadores transfirieron todos los derechos de propiedad intelectual desarrollados por la empresa a un comprador, incluido el sistema de logotipo del estudio. El estudio tenia archivos de versiones, hilos de Slack y una factura en PDF. Los abogados del comprador tenian una sola pregunta: demuestren que el estudio creo este trabajo antes de la fecha del contrato. El estudio no pudo hacerlo. La disputa costo CHF 210.000 para resolverse.

Si necesita probar la titularidad de la propiedad intelectual en una disputa de derechos de autor, la respuesta depende de una sola pregunta: puede demostrar cuando creo la obra y que contenia exactamente en ese momento? Esta guia explica que pruebas aceptan los tribunales de la UE y Suiza, por que los sellos de tiempo digitales son determinantes y la forma mas rapida de crear una prueba de creacion juridicamente admisible.
