In Brief
- Circle acquired IBM’s blockchain patent portfolio — more than 680 patent families and nearly 1,000 issued patents worldwide — for an undisclosed sum
- Circle says the deal makes it the largest blockchain patent holder in the United States, with IP spanning banking, insurance, supply-chain verification and secure cloud operations
- The portfolio will back USDC, the Circle Payments Network, the Arc blockchain and financial tools for AI agents, with CRCL shares rising as much as 5% on the news
Stablecoin issuer Circle has acquired IBM’s blockchain patent portfolio — more than 680 patent families and nearly 1,000 issued patents worldwide — in a deal the company says makes it the largest blockchain patent holder in the United States, according to The Block. Financial terms were not disclosed.
The portfolio spans foundational blockchain technology alongside applications in banking, financial services, insurance, enterprise infrastructure, supply-chain verification and secure cloud operations. Circle said the intellectual property directly supports USDC, the Circle Payments Network, its Arc blockchain and financial tools for AI agents, and that it plans to explore further commercial opportunities with IBM.
“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,” Circle general counsel and corporate secretary Sarah Wilson said, per Cointelegraph, adding that intellectual property is critical to advancing the company’s mission and expanding adoption of onchain infrastructure.
Why Circle wants IBM’s blockchain patents
IBM was one of enterprise blockchain’s earliest and biggest bettors, leaning heavily into supply-chain applications during the Hyperledger era. Its filing pace peaked in 2018-2019, when the company filed more than 500 blockchain patents, according to patent analytics firm GreyB figures cited by Cointelegraph, before slowing as enterprise blockchain cooled. A December 2025 PatSnap analysis credited IBM with 790 blockchain patents, placing it among the world’s top holders alongside Advanced New Technologies and Bank of America, CoinDesk notes.
For Circle, the acquisition is part defensive moat, part expansion toolkit. The company received its first patent — covering parallel blockchain data processing — only in December 2023 and joined the LOT Network, a nonprofit shielding members from patent trolls. Buying two decades of IBM R&D in one transaction instantly transforms its IP position as it builds out Arc, its own layer-1 blockchain, and payment rails increasingly aimed at AI-agent commerce.
CoinDesk adds a caveat worth noting: Circle did not disclose how many of the acquired patents were issued in the U.S., nor whether IBM retained licensing rights — so the “largest U.S. blockchain patent holder” title rests on Circle’s own characterization.
A patent land grab as stablecoins go mainstream
Investors liked the move: CRCL shares rose as much as 5% following the announcement, per The Block, after earlier premarket gains of around 2-2.5% reported by CoinDesk and Cointelegraph. USDC supply exceeded $74 billion as of Monday, and Circle’s post-IPO strategy has centered on owning more of its stack — from the Arc chain to payments infrastructure.
The deal also lands amid an intensifying scramble for crypto-financial infrastructure, the same week Fanatics bought a federally regulated exchange to enter prediction markets and tokenization firms continued stacking regulatory licenses. In a maturing industry, the moats are increasingly legal, not just technical.
For IBM, the sale closes a chapter on one of its most-hyped initiatives of the 2010s. The company that once pitched blockchain for everything from shipping manifests to food safety is handing its accumulated IP to a stablecoin issuer — a fairly clean summary of where enterprise blockchain’s center of gravity ended up.
