Securitize, the tokenized securities platform backed by BlackRock and Morgan Stanley, has asked a court to throw out patent infringement allegations from rival tZERO, according to a court filing reported on June 22. The company argues the dispute is driven by investor pressure rather than any legitimate IP concern. The case centers on foundational technology used to issue and manage regulated digital securities, and its outcome could shape how compliant tokenization infrastructure is built and licensed globally.

What tZERO Is Claiming

tZERO, an affiliate of retail company Beyond, Inc. (formerly Overstock.com), sent a cease-and-desist letter to Securitize asserting that two of its patents are being infringed. The first, U.S. Patent No. 11,216,802, covers "self-enforcing security token implementing smart-contract-based compliance rules." A smart contract is a self-executing program that runs on a blockchain and automatically enforces agreed-upon rules. The second, U.S. Patent No. 11,394,560, covers a "crypto integration platform." tZERO says Securitize's DS Protocol and Vault Registrar products, the core infrastructure Securitize uses to issue and track tokenized assets for institutional clients including BlackRock, fall within these claims.

tZERO holds a portfolio of 105 patents across 23 families and has signaled this enforcement campaign extends well beyond Securitize. The company says it has identified at least six other market participants it intends to contact with demand letters.

Securitize's Defence: This Is About Money, Not IP

In its court filing, Securitize challenged tZERO's motives, describing the action as "nothing more than the culmination of shareholder pressure to capitalize on the patents," according to reporting by The Block.

That framing maps directly onto tZERO's recent corporate history. In July 2025, Beyond, Inc. publicly demanded tZERO's board take "immediate action to create shareholder value," calling specifically for a public listing or SPAC deal. In April 2026, tZERO restructured its TZROP security tokens into preferred equity, with 84.6 percent of holders voting in favour of the conversion, and arranged up to $10 million in convertible note financing. Around the same time, tZERO CEO Alan Konevsky announced the company was "aggressively identifying other market opportunities where our intellectual property rights may be utilized, monetized or otherwise enforced."

The history between the two companies adds another layer of complexity. In May 2019, Securitize co-founder and CEO Carlos Domingo open-sourced the DS Protocol on GitHub, saying at the time that "it was important to us that developers had a viable venue to actually make a difference with their code, instead of developing on something that may never see actual use." At that same event, tZERO announced it would list security tokens built on that protocol, making the two firms formal partners. Notably, tZERO was the third secondary trading platform to support Securitize tokens, underscoring how broadly the protocol was being shared at the time. Securitize's current legal position may lean on that shared history.

A Fragile Moment for Securitize

The IP challenge lands at an uncomfortable time for Securitize. The company recently announced a SPAC merger with Cantor Equity Partners II that values it at $1.25 billion before the transaction closes. It is set to trade on Nasdaq under the ticker SECZ. Securitize reported Q1 2026 revenue of $19.5 million, up 39 percent year-on-year, with asset servicing fees growing 201 percent. It manages more than $4 billion in total assets under management, including its role as transfer agent for BlackRock's BUIDL fund, which holds roughly $2.5 billion and is widely used as collateral in decentralised finance. Legal analysts note that a patent cloud hanging over its core products could complicate or delay that public offering.

Legal Precedent Could Favour Securitize

Courts have recently made it harder to enforce blockchain-related patents. In February 2026, a New York federal court dismissed cryptocurrency exchange patents in BPROTOCOL Foundation v. Universal Navigation, ruling that "merely limiting the field of use of the abstract idea to a particular existing technological environment does not render the claims any less abstract." That decision applied the Alice doctrine, a two-step legal standard under Section 101 of U.S. patent law. The test asks first whether a claim is directed to an abstract idea, and second whether the claim contains an inventive concept sufficient to transform it into patent-eligible subject matter. Claims that amount to little more than generic compliance logic running on a blockchain face a meaningful challenge on those same grounds, and if tZERO's patents are characterised that way, they face a similar risk.

Why It Matters Beyond the US

The tokenized real-world asset market (securities, real estate, and commodities represented as blockchain tokens) reached approximately $31.76 billion in on-chain value in 2026, roughly 300 percent higher than the prior year. Forecasts project that figure could reach between $16 trillion and $30 trillion by 2030, a wide range reflecting the differing methodologies of various industry projections.

Emerging markets are expected to capture a significant share of that growth, according to Jesse Knutson, Head of Operations at BitFinex. Nigeria's Investments and Securities Act 2025 formally recognised digital assets as securities. Kenya enacted its VASP Bill in October 2025. South Africa has required licensing of crypto asset service providers since 2023.

These frameworks are creating real demand for the kind of compliant token infrastructure that Securitize and its competitors provide.

The DS Protocol was open-sourced in 2019 and has been available as a reference design for developers globally, including those in South Asia and Africa building regulated token systems. If tZERO prevails and the patents are upheld, any platform globally that uses technically similar token compliance architecture would need to consider licensing exposure. Developers in markets that have moved fastest on regulatory clarity would face new legal uncertainty over tools they have been building on for years.

What Comes Next

Securitize appears to have filed proactively, seeking to have tZERO's allegations rejected before any formal suit could be brought. That approach is consistent with a declaratory judgement action, though the specific procedural form has not been independently confirmed from court records. tZERO's stated intention to pursue at least six additional companies means the case is unlikely to remain a bilateral dispute. How courts weigh the open-source history of the DS Protocol and the February 2026 blockchain patent precedent will determine not just the outcome of this case, but how broadly US patent law reaches into the global infrastructure of tokenized finance.
