tZERO Group, Inc., a blockchain-based financial infrastructure provider, announced today that it has sent a cease-and-desist letter to Securitize, Inc., alleging infringement of two of its patents related to self-enforcing security token compliance and crypto integration. The move is part of a broader strategic review of tZERO’s intellectual property portfolio, which comprises 105 patents across 23 families worldwide, and signals an aggressive stance on protecting its innovations in the tokenized securities market.
According to the company, Securitize’s DS protocol and Vault Registrar infringe on U.S. Patent Nos. 11,216,802 and 11,394,560. tZERO is also investigating additional patents, including those covering crypto multiple security asset creation, upgradeable security tokens, consolidated order books, and whitelisted transaction address verification, for potential infringement by Securitize and other market participants.
Beyond Securitize, tZERO’s investigation has identified products from at least six other companies in sectors such as regulated real-world asset and digital asset securities platforms, institutional infrastructure, prime brokerage, decentralized sequencing, and decentralized exchanges. The company expects to send demand letters to these parties after completing its analysis of patent claims.
“tZERO and its investors have dedicated substantial time, research, and capital over the years to develop a leading intellectual property portfolio in the tokenization industry,” the company stated. “As this industry scales and matures, tZERO will remain vigilant in protecting its valuable intellectual property, market position and shareholders’ investment.”
The announcement follows an April 30 update in which tZERO highlighted 10 patents across five families, including self-enforcing compliance, upgradeable tokens, splittable tokens, federated PII services, and crypto integration. Today, the company also previewed additional patent families covering core infrastructure technologies: crypto multiple security asset creation and redemption (7 patents), consolidated order books (3 patents), decentralized trading systems for fair ordering (2 patents), and obfuscation of intent in transactions (9 patents).
These technologies address tokenized fund creation and redemption, cross-venue liquidity management, decentralized trade sequencing, and privacy-preserving transaction architectures. tZERO emphasized that its portfolio focuses on enabling compliant, scalable, and interoperable tokenized capital markets infrastructure.
The enforcement actions come as the tokenized securities market grows, with increasing competition and innovation. tZERO’s patent portfolio, built since 2014, positions it as a key player in the evolving landscape. The company expects to provide further updates on its patent strategy, enforcement, and licensing initiatives. Market participants interested in licensing may contact tZERO at sales@tzero.com.
