tZERO Sends Cease-and-Desist Letter to Securitize, Targets Additional Firms in Patent Enforcement Push - citybuzz -

tZERO Group, Inc. has initiated a strategic enforcement of its intellectual property portfolio by issuing a cease-and-desist letter to Securitize, Inc. regarding alleged patent infringement. The dispute centers on U.S. Patent Nos. 11,216,802 and 11,394,560, which cover foundational technologies for security token compliance, smart-contract-based registries, and crypto integration. tZERO, which holds 105 patents across 23 families, claims these technologies are utilized in Securitize’s DS protocol and Vault Registrar. Beyond this specific action, tZERO has identified at least six other market participants across sectors like regulated RWA platforms and decentralized exchanges that may be infringing on its broader IP portfolio. This portfolio includes patents related to consolidated order books, decentralized trade ordering, and privacy-preserving transaction techniques. By aggressively protecting its intellectual property, tZERO aims to solidify its market position as the tokenized securities industry matures. The outcome of these enforcement efforts could force competitors into licensing agreements or trigger legal disputes that fundamentally reshape the competitive landscape for digital asset infrastructure. This development highlights the increasing importance of proprietary technology in the regulated RWA sector as firms move to defend their market share.
