Circle just bought the patent library IBM spent more than a decade assembling. The USDC issuer announced on July 27, 2026 that it has acquired IBM’s blockchain patent portfolio — more than 680 patent families and nearly 1,000 issued patents worldwide — in a deal whose financial terms were not disclosed. The purchase vaults Circle from a modest in-house IP position to, by Decrypt’s accounting, the largest blockchain patent holder in the United States.
From one patent to a thousand in three years
The scale of the jump is what makes this deal unusual. Circle received its first-ever patent in December 2023, covering parallel blockchain data processing — a technique for verifying multiple groups of transactions simultaneously. IBM, by contrast, had been accumulating blockchain IP since its mid-2010s enterprise blockchain push: Decrypt cites patent analytics firm PatSnap crediting IBM with 790 US blockchain patents as of December 2025, more than any other American company, with Bank of America a distant second at roughly 200.
In one transaction, Circle absorbed effectively all of that. “The portfolio comprises over 680 patent families and nearly 1,000 issued patents worldwide, spanning foundational blockchain technology, banking, financial services, insurance, enterprise infrastructure, supply chain verification, and secure cloud operations,” Circle said in its announcement.
Where Circle plans to point the portfolio
Circle is explicit that the patents are meant to underwrite its whole product stack, not sit in a drawer. The company says the expanded IP position “directly supports Circle’s foundation for building the internet financial system, including USDC, Circle Payments Network, Arc, and a growing suite of onchain products and agentic financial tools.” Arc is Circle’s own payments-focused blockchain built for institutional finance, and the agentic tools are AI-driven programs designed to execute financial transactions autonomously.
“Intellectual property is critical to advancing our mission and expanding adoption of onchain infrastructure,” said Sarah Wilson, Circle’s General Counsel and Corporate Secretary, in the announcement. “IBM has been a pioneer in technological innovation, and this acquisition expands Circle’s ability to advance the infrastructure that powers global, internet-native finance.”
Defense, offense, and the LOT Network question
Before this acquisition, Circle’s main IP posture was defensive: the company had joined the LOT Network, a cross-industry coalition whose members agree to shield one another from patent-assertion entities — firms that buy patents purely to extract settlement fees. That membership still matters, but the calculus changes when you hold nearly 1,000 issued patents instead of a handful. Circle now has enough IP to go on offense against competitors if it ever chooses to, and it has not said whether it plans to. For rivals building stablecoin settlement, enterprise blockchain rails, or supply-chain verification systems, the ownership of this portfolio just moved from a neutral party that had largely exited crypto to the most aggressive commercial operator in the stablecoin market.
The IBM twist: selling the IP while backing USDC’s rival
The strangest wrinkle in the deal is who the seller is aligned with. IBM is a confirmed partner in Open Standard, the consortium behind Open USD — a rival stablecoin that launched on June 30 with more than 140 backers including Visa, Mastercard, Google, BlackRock, Stripe, and Coinbase, per Decrypt’s reporting. Open USD’s model distributes reserve income to its partner distributors rather than retaining it, a structure aimed squarely at the revenue line Circle’s business depends on. In other words: IBM sold Circle its foundational blockchain IP while simultaneously backing the stablecoin engineered to erode USDC’s market share.
Markets read the deal as a net positive for Circle regardless — Decrypt notes CRCL shares rose 2.57% on Monday following the announcement.
The takeaway for anyone building on stablecoin rails: the patent map of US blockchain infrastructure was redrawn in a single afternoon. Circle didn’t just buy protection; it bought the deepest claim on the foundational techniques of enterprise blockchain at exactly the moment stablecoin settlement is going mainstream — and the company that sold it is hedging both sides of the fight.
