Securitize and tZERO clash over tokenization patents as Wall Street moves onchain

Two of the biggest firms in tokenization are headed for a legal showdown after tZERO sent Securitize a cease-and-desist letter accusing the company of infringing patents tied to blockchain-based securities infrastructure. Securitize responded by filing a lawsuit in the U.S.

District Court in Delaware seeking a declaratory judgment that it does not infringe tZERO's patents. Tokenization — converting ownership rights in assets like stocks, bonds or real estate into blockchain tokens — has attracted growing interest from global banks, exchanges and asset managers.

Firms including BlackRock, JPMorgan, Nasdaq and the NYSE have been involved in projects that aim to streamline issuance, settlement and ownership tracking. Market forecasts range widely, with Citi estimating a $5 trillion market by 2030 and a separate report from Boston Consulting Group and Ripple projecting $18.9 trillion by 2033.
