Cycaltrust Inc. obtained Japanese patent No. 7910837 for its Appraisal Certification System, which generates Chain of Custody and Chain of Provenance trails for physical, digital, and hybrid assets across organizations and judges authenticity from the continuity, consistency, and mutual correspondence of the two. The patent covers implementation work built on ISO 26345, the blockchain provenance standard the company is drafting in ISO/TC307 (WG8).
Patent No. 7910837 covers a system for judging the strength of authenticity from how two evidence trails line up. Chain of Custody tracks who held an asset. Chain of Provenance tracks where it came from. The system applies across physical products, digital content, and hybrid categories such as real-world assets and digital twins, spanning multiple organizations.
The patent sits on top of ISO 26345, a blockchain standard Cycaltrust is drafting as original text lead in ISO/TC307 (WG8). Under the company's split, ISO 26345 opens a common verification framework between organizations while the patent portfolio, more than 40 patents, protects the implementation built on it.
