Enigio has been granted a second patent in Singapore covering technology behind trace:original, further strengthening the intellectual property protection for its solution for creating and managing digital original documents.
The patent,“Method and system for registering digital documents”, was granted to Enigio AB on 24 July 2026.
The new patent covers methods and systems for registering and updating versioned digital documents in formats that can include binary-coded information and non-textual content. The patent specifically covers page-oriented document formats such as PDF and includes provisions for working with embedded metadata and attachments.
This is particularly relevant in trade, transport, finance and other document-intensive processes, where established document formats such as PDFs are already deeply embedded in everyday workflows. The patented technology enables these types of documents to be used as verifiable digital originals while retaining their familiar format and appearance.
It also covers the secure management of digital documents throughout their lifecycle, including versioning, changes of ownership, verification and cancellation. The document itself does not need to be stored in the digital document register, allowing its contents to remain with the parties using it.
Göran Almgren, Director, New Markets at Enigio, said:
“This patent further strengthens the protection around trace:original and the approach we have taken to digital originals. An important part of that approach is making it possible to work with familiar document formats, rather than asking businesses to replace established documents and processes simply because they are moving from paper to digital.”
The Singapore patent adds to Enigio’s existing patent protection for the technology behind trace:original.
