tZERO Group, Inc., a pioneer in blockchain-based financial infrastructure, provided an update on June 15, 2026, regarding its intellectual property portfolio enforcement and highlighted additional patented inventions that underpin the evolution of tokenized capital markets. The company revealed that it has sent a cease-and-desist letter to Securitize, Inc., alleging infringement of two tZERO patents: U.S. Patent No. 11,216,802, titled “Self-enforcing Security Token Implementing Smart-contract-based Compliance Rules Consulting Smart-contract-based Global Registry of Investors,” and U.S. Patent No. 11,394,560, titled “Crypto integration platform.” tZERO stated that Securitize’s DS protocol and Vault Registrar infringe these patents.
This enforcement action follows tZERO’s April 30, 2026, update on its portfolio review, which highlighted 10 patents across five families, including Self-Enforcing Security Token Compliance System, Upgradable Security Token Architecture, and Crypto Integration Platform. tZERO’s broader portfolio comprises 23 patent families with 105 patents worldwide, focusing on compliant, scalable, and interoperable tokenized capital markets infrastructure. The company emphasized its commitment to protecting its intellectual property and shareholders’ investment as the industry scales.
In addition to the Securitize action, tZERO’s investigation identified products from at least six other market participants in sectors such as Regulated RWA & Digital Asset Securities Platforms, Institutional Infrastructure, and Decentralized Exchanges that likely infringe its patents. tZERO expects to send demand letters to these parties after completing its analysis. The patents under investigation include 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).
tZERO also highlighted additional patent families related to core infrastructure technologies. These include Crypto Multiple Security Asset Creation and Redemption Platform (US11,704,733B2; US12,469,079B2), with seven issued patents covering blockchain-based creation and redemption for tokenized funds and multi-asset digital securities. The Consolidated Order Book from Multiple Asset Exchanges family (US11,436,673B2) includes three patents for aggregating liquidity across trading venues. The Decentralized Trading System for Fair Ordering and Matching of Trades (US10,937,083B2) comprises two patents for distributed node consensus mechanisms. Finally, the Obfuscation of Intent in Transactions Using Cryptographic Techniques family (US10,552,829B2) includes nine patents for privacy-preserving transaction techniques.
These technologies reflect tZERO’s focus on regulated infrastructure for tokenized capital markets, spanning issuance, trading, liquidity aggregation, custody, settlement, and transaction privacy. tZERO stated it will continue evaluating its portfolio and expects to provide further updates on patent strategy, enforcement, and licensing activities.
