Securitize filed a lawsuit in the U.S. District Court in Delaware on June 22 seeking a declaratory judgment that it does not infringe patents owned by tZERO. The filing came one week after tZERO sent Securitize a cease-and-desist letter accusing the firm of violating patents related to blockchain-based securities infrastructure.
The patents at issue cover self-enforcing compliance controls for security tokens and crypto integration systems. tZERO said its investigation concluded that Securitize's DS Protocol and Vault Registrar infringe those patents. The company stated it is also investigating potential infringement by at least six other firms across tokenization, institutional crypto infrastructure and decentralized finance.
Securitize rejected the claims. "tZERO's allegations are without merit and run counter to the spirit of fair play that defines our industry at its best," the company said in a statement. tZERO launched in 2014 and holds 105 patents globally across 23 patent families related to tokenized capital markets.
NYSE parent Intercontinental Exchange made a strategic investment in tZERO in 2022, and the firm unveiled plans to go public in 2025. Securitize was founded in 2017 and works with BlackRock, Apollo, KKR, Hamilton Lane and VanEck on tokenized funds. Earlier in 2026 Securitize announced a deal with the New York Stock Exchange to develop infrastructure for tokenized equities trading and aims to go public later this year through a merger with a Cantor-backed entity.
Citi has estimated tokenized assets could reach a $5 trillion market capitalization by 2030. A report from Boston Consulting Group and Ripple projected a market worth $18.9 trillion by 2033. Global banks, exchanges and asset managers including BlackRock, JPMorgan, Nasdaq and NYSE have embraced tokenization.
