tZERO Group, Inc., a blockchain-based financial infrastructure provider since 2014, announced on June 15, 2026, that it has sent a cease and desist letter to Securitize, Inc. for alleged infringement of two tZERO patents related to self-enforcing security tokens and crypto integration platforms. The move is part of a broader strategic review and enforcement of tZERO's intellectual property portfolio, which comprises 105 patents across 23 families worldwide.
The patents in question are U.S. Patent Nos. 11,216,802 titled “Self-enforcing Security Token Implementing Smart-contract-based Compliance Rules Consulting Smart-contract-based Global Registry of Investors” and 11,394,560 titled “Crypto integration platform”. tZERO claims that Securitize's DS protocol and Vault Registrar infringe these patents. Additionally, tZERO is investigating potential infringement by at least six other market participants in sectors including Regulated RWA & Digital Asset Securities Platforms, Institutional Infrastructure, Prime Brokerage & Liquidity Aggregators, Decentralized Sequencing, Fair Ordering & Crypto Infrastructure, and Decentralized Exchanges & Specialized DeFi Dark Pools. The company expects to send demand letters after completing its analysis.
tZERO highlighted additional patent families from its portfolio that support regulated digital asset securities and tokenized financial markets. These include technologies for crypto multiple security asset creation and redemption (U.S. Patent Nos. 11,704,733 and 12,469,079), consolidated order book from multiple asset exchanges (U.S. Patent No. 11,436,673), decentralized trading system for fair ordering and matching (U.S. Patent No. 10,937,083), and obfuscation of intent in transactions using cryptographic techniques (U.S. Patent No. 10,552,829). These patents cover core infrastructure such as tokenized fund creation and redemption, cross-venue liquidity management, decentralized trade ordering, and privacy-preserving transactions.
The enforcement actions underscore tZERO's commitment to protecting its intellectual property as the tokenization industry scales.
