A co-founder of 21Shares has cautioned that the current enthusiasm surrounding tokenization is outpacing the practical readiness and capabilities of Wall Street institutions. This sentiment comes as tZERO Group, a blockchain-based financial infrastructure provider, announced it is actively enforcing its intellectual property rights within the tokenization sector.
tZERO has determined that certain products and services offered by Securitize, Inc., specifically its DS protocol and Vault Registrar, infringe upon two of tZERO's 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.” Consequently, tZERO has issued a cease and desist letter to Securitize.
This action is part of a broader strategic review of tZERO's intellectual property, which encompasses 23 patent families and a total of 105 patents globally. The company is also investigating potential infringement by at least six other market participants across various sectors, including regulated digital asset securities platforms, institutional infrastructure, and decentralized exchanges. tZERO stated its intention to send demand letters to these entities following the conclusion of its analysis.
In a prior update on April 30, 2026, tZERO had highlighted 10 patents across five families, focusing on self-enforcing security token compliance, upgradable security token architecture, splittable security token structure, federated PII service for broker-dealers, and crypto integration platforms. The company is committed to protecting its innovations as the tokenized capital markets industry scales and matures.
