GENEVA, SWITZERLAND, June 16, 2026 (GLOBE NEWSWIRE) — SEALSQ has obtained a European patent for “back-to-physical” NFT technology that enables trusted semiconductor authentication.
SEALSQ Corp. (NASDAQ: LAES) (“SEALSQ” or the “Company”), a leading semiconductor, public key infrastructure, post-quantum technology, and secure digital identity solutions, today announced that the European Patent Office (EPO) has granted a split patent covering the essential “return to physical” claims of its NFT core invention.
The newly granted claims are specifically designed to deliver non-fungible tokens (NFTs) directly into semiconductors, creating a tamper-resistant, hardware-integrated connection between digital assets and physical chips. This breakthrough enables NFTs to be permanently and verifiably pinned to secure silicon, creating an immutable chain of origin, authenticity, ownership and lifecycle management for semiconductor components deployed in critical infrastructure and high-value industries.
“I am pleased to announce that the EPO has granted this divisional patent with respect to the ‘return to physical’ claims of our NFT patent
“,”
said Jean-Pierre Inguent, CTO at SEALSQ. “These claims apply particularly to NFTs made available in semiconductors and represent an important milestone in our strategy to integrate digital and physical trust at the silicon level. By embedding digital identities directly into chips, we are enabling a new generation of trusted devices capable of proving their authenticity, provenance, ownership and operational integrity throughout their entire lifecycle.”
Bridging the digital and physical worlds
While NFTs are traditionally associated with digital art and virtual assets, SEALSQ’s patented innovation expands the concept into the physical world by enabling each semiconductor to carry a unique, cryptographically secured NFT tied to its manufacturing, certification, ownership and operational history.
