tZERO Group, Inc., a blockchain-based financial infrastructure provider since 2014, provided an update on its intellectual property enforcement actions and highlighted additional patent families supporting tokenized capital markets. On April 30, 2026, tZERO disclosed details of its 105-patent portfolio, including 10 patents across 5 families. Now, the company has determined that certain products and services of Securitize, Inc., including its DS protocol and Vault Registrar, infringe tZERO’s patents.
tZERO sent a cease-and-desist letter to Securitize regarding U.S. Patent Nos. 11,216,802 and 11,394,560, titled “Self-enforcing Security Token Implementing Smart-contract-based Compliance Rules Consulting Smart-contract-based Global Registry of Investors” and “Crypto integration platform,” respectively. The company is also investigating further infringement of patents such as U.S. Patent Nos. 11,704,733 (“Crypto multiple security asset creation and redemption platform”), 11,410,159 (“Upgradeable Security Token”), 11,436,673 (“Consolidated Order Book from Multiple Asset Exchanges”), 12,051,078 (“Account Owner Funding of Know Your Customer and Accredited Investor Verification Renewal and Monitoring Charges Through Coin Payment”), and 12,099,996 (“Verifying Transaction Address Is Whitelisted Before Allowing Transfer to Transaction Address of Self-Regulating Token”).
Beyond Securitize, tZERO’s investigation identified products from 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 that likely infringe on its patents. tZERO is analyzing its patent claims against those products and expects to send demand letters after completing its investigation.
tZERO emphasized its substantial investment in developing its intellectual property portfolio, which now consists of 23 patent families encompassing 105 patents worldwide. The portfolio focuses on enabling compliant, scalable, and interoperable tokenized capital markets infrastructure. As the industry scales, tZERO intends to protect its intellectual property, market position, and shareholders’ investment.
In addition to enforcement, tZERO highlighted new patent families covering core infrastructure technologies. These include the Crypto Multiple Security Asset Creation and Redemption Platform (US11,704,733B2; US12,469,079B2), with 7 patents issued worldwide, relating to blockchain-based creation and redemption of tokenized funds and multi-asset digital securities.
