Circle Buys ~1,000 IBM Blockchain Patents for USDC, Arc

Circle has acquired nearly 1,000 IBM blockchain patents covering more than 680 patent families across banking, financial services, insurance, supply-chain verification and secure cloud operations, the company said in a July 27 statement. Circle called the deal the foundation of its push to connect stablecoins with banks and payment networks, and said it now holds the largest blockchain patent portfolio in the United States. The patents will feed USDC, Circle Payments Network, the Arc blockchain and a growing suite of onchain and agentic financial tools, while the two firms also plan to explore additional commercial work together.

Why it matters

The portfolio lands as stablecoins move past crypto trading into settlement, treasury operations and mainstream payments, where IBM spent years patenting ways to connect blockchain systems with conventional financial networks. Specific IBM filings now in the public domain give a sense of the surface area. US11599858B2, "Blockchain settlement network," covers moving digital value over a blockchain alongside an off-chain payment and monitoring the transaction until the external transfer settles, and runs through 2041. US11676117B2, "Blockchain compliance verification network," addresses AML, KYC, sanctions compliance and ISO 20022 payment messaging. A pending US application, US20220172198A1, goes further into card-style payments, describing a conventional payment network operating in parallel with a blockchain settlement network, including a token service provider that can trigger blockchain settlement while the underlying payment is being processed.

Market impact

Circle General Counsel Sarah Wilson said "intellectual property is critical to advancing our mission and expanding adoption of onchain infrastructure." Clear Street told CryptoSlate the portfolio strengthens Circle's defensive position in cross-licensing and partnership negotiations, and could provide ammunition in patent litigation as the GENIUS Act draws established financial companies with substantial patent portfolios into stablecoins. The brokerage framed the broader IBM relationship as "strategic optionality," with potential exposure for Circle Payments Network, Arc and tokenization products to IBM's bank and enterprise client base.

USDC is already taking a larger share of economically meaningful stablecoin activity. USDC accounted for roughly 70% of adjusted stablecoin transaction volume in the first half of 2026, against about 25% for Tether's USDT, according to Visa's Onchain Analytics data.
