SEALSQ CorpSEALSQ secured a European patent for Back-to-Physical NFT technology, a key technological milestone.
WISeKey's subsidiary WISe.ART has become the world's first hardware-authenticated art platform while its other subsidiary SEALSQ Corp. has been granted a landmark divisional patent by the European Patent Office for its Back-to-Physical NFT technology. The patent covers the method of provisioning NFTs directly into tamper-proof semiconductors, creating an immutable, hardware-rooted link between a digital asset and a physical object. This enables WISe.ART to offer silicon-sealed provenance, ownership history, and authenticity certification that is independently verifiable and secured with post-quantum cryptography. The patent portfolio now spans a Swiss priority filing, the granted European divisional patent, a pending US application, and a further EPO divisional under examination. WISe.ART operates within WISeKey's global trust infrastructure, which secures over 2.6 billion devices, and targets the approximately $65 billion annual global art market.
