tZERO Group, Inc., a leader in blockchain-based financial infrastructure since 2014, today provided an update on enforcement actions taken as part of its ongoing strategic review of its intellectual property assets. The company highlighted additional patent families from its portfolio that support regulated digital asset securities and tokenized financial markets.
On April 30, 2026, tZERO updated its portfolio review, detailing 10 patents across 5 families, including Self-Enforcing Security Token Compliance System, Upgradable Security Token Architecture, Splittable Security Token Structure, Federated PII Service for Broker-Dealers, and Crypto Integration Platform. The company indicated it is identifying commercialization and enforcement opportunities.
As part of this work, tZERO determined that certain products of Securitize, Inc., including their DS protocol and Vault Registrar, infringe tZERO patents. Today, tZERO sent a cease and desist letter to Securitize relating to 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 is continuing to investigate further infringement of its patents, including but not limited to U.S. Patent Nos. 11,704,733, 11,410,159, 11,436,673, 12,051,078, and 12,099,996.
Additionally, tZERO’s investigation identified products from at least six other market participants in sectors like Regulated RWA & Digital Asset Securities Platforms, Institutional Infrastructure, and Decentralized Exchanges that likely infringe on its patents. The company expects to send demand letters after completing its analysis.
tZERO’s broader portfolio consists of 23 patent families encompassing 105 patents worldwide, focusing on compliant, scalable, and interoperable tokenized capital markets infrastructure. The company highlighted additional patent families relating to core infrastructure technologies, including Crypto Multiple Security Asset Creation and Redemption Platform (US11,704,733B2; US12,469,079B2) with 7 patents issued worldwide, covering blockchain-based creation and redemption for tokenized funds. The Consolidated Order Book from Multiple Asset Exchanges (US11,436,673B2) family includes 3 patents for aggregating liquidity across venues. The Decentralized Trading System for Fair Ordering and Matching of Trades (US10,937,083B2) family includes 2 patents for decentralized trade sequencing. The Obfuscation of Intent in Transactions Using Cryptographic Techniques (US10,552,829B2) family includes 9 patents for transaction privacy.
These technologies reflect tZERO’s focus on regulated infrastructure for tokenized capital markets, spanning issuance, trading, liquidity aggregation, custody, settlement, and transaction privacy. tZERO will continue evaluating its portfolio and expects further updates on patent strategy, enforcement, and licensing activities.
