SEALSQ, a subsidiary of WISeKey International, has secured a divisional patent from the European Patent Office for its “Back-to-Physical” technology, marking a major step in linking digital assets with physical products.
The patented innovation allows non-fungible tokens (NFTs) to be directly embedded into secure semiconductor chips, creating a permanent and tamper-proof connection between digital assets and their real-world counterparts. The company said the technology could significantly improve the security, authenticity, and traceability of NFTs, addressing growing concerns over fraud and asset verification in digital ownership markets.
SEALSQ, traded under the ticker LAES, specialises in secure microcontrollers and post-quantum cryptography solutions. Its technology is widely used in applications such as multi-factor authentication, industrial automation, and digital identity protection.
The patent strengthens SEALSQ’s position in the fast-evolving semiconductor and blockchain sectors, as businesses increasingly explore ways to connect physical products with tokenised digital ownership.
The company currently holds a market capitalisation of approximately $675 million and generates much of its revenue from North America, alongside operations across Europe, the Middle East, Africa, Asia-Pacific, and Latin America.
While the patent win highlights strong innovation potential, investors remain cautious. SEALSQ’s GF Score stands at 42 out of 100, indicating below-average long-term growth potential. The company’s financial strength remains solid, though profitability and growth metrics have been weaker.
Adding to market concerns, company insiders sold nearly $900,000 worth of shares over the past three months, with no reported insider buying activity.
The new patent could help SEALSQ expand its role in securing digital assets as NFT applications continue to grow across luxury goods, collectibles, and supply chain verification.
