Points of Focus

• Circle acquired nearly 1,000 IBM blockchain patents across 680 patent families.
• The deal makes Circle the largest blockchain patent holder in the United States.
• IBM and Circle also plan to explore additional commercial partnerships.

Circle has acquired IBM’s blockchain patent portfolio, giving the USDC (USDC) issuer control of nearly 1,000 issued patents and making it the largest blockchain patent holder in the United States. Financial terms of the transaction were not disclosed.

The portfolio spans more than 680 patent families covering blockchain infrastructure, banking, financial services, enterprise systems, supply chain verification, and secure cloud operations. Circle said the intellectual property will support products including USDC, Circle Payments Network (CPN), Arc, and its growing suite of AI-powered financial services.

“Intellectual property is critical to advancing our mission and expanding adoption of onchain infrastructure,” said Sarah Wilson, general counsel and corporate secretary at Circle.

IBM exits, while Circle doubles down

The acquisition marks a shift for two companies that have taken different paths in blockchain.

IBM spent much of the last decade developing enterprise blockchain technology, filing hundreds of patents and working with banks, logistics companies, and supply-chain operators through initiatives such as IBM Blockchain and Hyperledger. As enterprise blockchain demand cooled, IBM gradually reduced its direct blockchain business while keeping one of the industry’s deepest patent portfolios.

Circle, by contrast, has expanded beyond stablecoins. Since going public, the company has broadened its focus to institutional payments, tokenized assets, and blockchain infrastructure, receiving final approval earlier this month to establish a US national trust bank. The IBM portfolio gives Circle years of accumulated research without having to build the patents internally.

More than a defensive move

Patent acquisitions rarely affect crypto prices directly, but they can influence competition over the longer term.

The patents could strengthen Circle’s position if disputes emerge over blockchain infrastructure or enterprise financial technology. They also create opportunities for licensing agreements and joint commercial projects, with Circle and IBM confirming they intend to explore additional partnerships beyond the sale.

The timing is also significant. Circle has spent recent months building out products beyond USDC, including Circle Payments Network and Arc, while facing fresh competition in the stablecoin market.

Notably, IBM is also a partner in Open Standard, the consortium behind Open USD — a stablecoin initiative that aims to compete with USDC. That means IBM has sold its blockchain intellectual property to Circle while remaining involved in a competing payments project.

Circle’s shares rose after the announcement, suggesting investors viewed the acquisition as another step in the company’s push to become a broader blockchain infrastructure provider rather than solely a stablecoin issuer.
