SEALSQ gets EPO divisional patent for Back-to-Physical NFT tech

SEALSQ Corp received an EPO divisional patent tied to its “Back-to-Physical” NFT technology, with WISe.ART described as using that foundation for hardware-rooted provenance. The change matters because it targets a way to connect digital tokens to physical objects through secure semiconductor chips, rather than relying on a software-only link.

The company said the patent covers core claims for provisioning non-fungible tokens directly into a tamper-proof semiconductor and embedding a unique cryptographically secured digital identity in the physical chip. WISe.ART is described as operating within a digital trust ecosystem built around WISeKey’s PKI and root-of-trust infrastructure, and SEALSQ’s post-quantum secure microcontrollers and certified semiconductors.

Within that structure, the “Back-to-Physical” approach ties authenticity to a secure microcontroller physically associated with artwork and treats the chip as the certificate. The digital product passport model is described as carrying creation details, ownership history, exhibition records, valuation events, and transfer documents, and as surviving changes associated with auction houses, estate transfers, and generations of collectors.

The EPO divisional patent grant formed part of a broader patent portfolio that included a Swiss priority filing and additional filings in Europe and the US, with further EPO divisional claims under examination. Carlos Moreira, CEO of SEALSQ, said, “WISe.ART was built on the conviction that trust in art cannot be a software promise, it must be a hardware guarantee. Today’s EPO patent grant transforms that conviction into protected intellectual property. For the first time, collectors, institutions, and artists have access to provenance that is not only blockchain-recorded but silicon-sealed, post-quantum secured, and independently verifiable without any centralized authority.”

Forward-looking statements in the communication covered expectations for strategy, financial performance, results of operations, market data, and future events, along with risk factors that could cause actual results to differ.
