Securitize Files Delaware Lawsuit Against tZERO in Patent Dispute

The conflict centers on Securitize’s DS Protocol and Vault Registrar, which tZERO alleges infringe upon its intellectual property portfolio. tZERO, which has operated in the digital asset space since 2014, claims to hold 105 patents across 23 families related to tokenized capital markets. Following a cease-and-desist letter, Securitize publicly rejected the allegations, characterizing them as meritless and contrary to fair competition.

This legal friction arrives at a critical juncture for Securitize, which is currently preparing for a June 29 shareholder vote regarding its merger with Cantor Equity Partners II. Should the deal proceed, the firm intends to list on the New York Stock Exchange under the ticker SECZ. Securitize currently manages over $4 billion in assets and maintains significant partnerships, including its role as the transfer agent for BlackRock’s BUIDL fund. As the market for onchain securities continues to expand—with tokenized equities reaching a $5.5 billion market capitalization—the outcome of this case may establish a significant precedent for how infrastructure providers defend their technical property in the burgeoning regulated finance sector.
