SEALSQ Corp said the European Patent Office granted a divisional patent covering the core “Back-to-Physical” claims of the company’s NFT invention. The patent centers on provisioning Non-Fungible Tokens into semiconductors, aiming to create a tamper-proof, hardware-rooted link between digital assets and physical chips.

The company tied the granted claims to establishing an immutable chain of provenance, authenticity, ownership, and lifecycle management for semiconductor components deployed in critical infrastructure and high-value industries. SEALSQ also stated that the divisional grant aligns with its post-quantum security approach and expands its intellectual property portfolio in post-quantum cryptography, Root-of-Trust semiconductors, and authenticated digital assets.

In the “Back-to-Physical” approach, SEALSQ said the claims are designed for provisioning NFTs directly into semiconductors to connect digital assets with physical chips. The company described the result as a hardware-rooted authentication mechanism intended to anchor NFTs to secure silicon and support verification through an immutable chain of information.

Jean Pierre Enguent, CTO of SEALSQ, said, “I am pleased to announce that the EPO has granted this divisional patent relating to the ‘Back-to-Physical’ claims of our NFT patent.” He added, “These claims are particularly applicable to NFTs being provisioned into semiconductors and represent a significant milestone in our strategy to fuse digital and physical trust at the silicon level.” SEALSQ also stated that a corresponding USPTO application remained pending and that another EPO divisional application was under examination. It said an overview of the “Back-to-Physical” aspects of the patent was available upon request, and that it would provide updates as additional patents were granted.
