Real-world asset tokenization platform Securitize has filed a federal lawsuit against digital securities infrastructure firm tZERO, seeking a declaratory judgment that its products do not infringe on two patents held by tZERO. The complaint, lodged in the U.S. District Court for the District of Delaware, follows allegations that Securitize's DS Protocol and Vault Registrar products violate tZERO's patents related to self-enforcing security tokens and crypto integration infrastructure.
Securitize asserts that tZERO's claims are meritless and represents an attempt to pressure companies that have achieved commercial traction in tokenized securities. The company claims tZERO sent a cease-and-desist letter demanding that Securitize stop commercializing the products by June 18, threatening injunctive relief and monetary damages. Securitize rejected the allegations, arguing that its products lack critical elements such as trade execution and transaction-signing functions that are central to the patent claims.
The lawsuit arrives amid growing attention on real-world asset tokenization, with asset managers, broker-dealers, funds, and blockchain infrastructure providers increasingly exploring on-chain securities. Securitize is asking the court for a declaratory judgment of non-infringement and to block tZERO from asserting the patents against it. The public statement from Securitize described tZERO's allegations as "without merit and run counter to the spirit of fair play that defines our industry at its best."
The case could have broader implications for the digital securities sector. With tokenization infrastructure becoming commercially valuable, intellectual property disputes may become a more common part of the competitive landscape. The court's decision may help define how aggressively digital securities firms can use patents to challenge rivals as the market matures.
