Circle has pulled off one of the largest blockchain patent transfers on record. By scooping up IBM’s portfolio — more than 680 patent families and nearly 1,000 issued titles worldwide — the USDC issuer has become the top US holder and locked down its infrastructure against a wave of lawsuits sweeping the crypto industry.
🔑 Key takeaways
- Acquisition of roughly 1,000 blockchain patents from IBM for an undisclosed sum
- Circle leapfrogs Bank of America to claim the top US spot
- Patents will support USDC, the Circle Payments Network, Arc and AI-agent financial tooling
- According to COPA, 58% of US crypto patent suits are filed by non-practicing entities (NPEs)
- CRCL shares closed +3.7% on July 27, 2026
A strategic portfolio at the core of onchain finance
Announced on July 27, 2026, the deal covers over 680 patent families and roughly 1,000 issued titles worldwide. The portfolio spans core blockchain technology, banking, financial services, insurance, enterprise infrastructure, supply chain verification and secure cloud operations, according to a press release from Circle Internet Group, Inc. (NYSE: CRCL).
In its own words, Circle is now the top holder of blockchain patents in the United States. The patents will feed four priorities: the USDC stablecoin, the Circle Payments Network, the Arc blockchain, and financial tools built for autonomous AI agents. Circle and IBM also plan to explore future commercial opportunities together.
« Intellectual property is essential to advancing our mission and expanding the adoption of onchain infrastructure. IBM has been a pioneer of technological innovation, and this acquisition expands Circle’s ability to advance the infrastructure powering the internet-native global financial system. »
Sarah Wilson, Chief Legal Officer and General Secretary of Circle
IBM, the enterprise blockchain pioneer, exits the commercial game
The portfolio traces back to IBM’s heyday in « enterprise blockchain. » According to a December 2025 PatSnap analysis, IBM held 790 issued US blockchain patents, ranking first ahead of Bank of America and its roughly 200 titles. Big Blue was the top filer in the US between 2016 and 2019.
IBM seeded the ecosystem with several flagship platforms: contributing the Hyperledger Fabric codebase to the Linux Foundation, launching Food Trust to trace food at Walmart and Carrefour, and TradeLens with shipping giant Maersk to digitize ocean freight — 94 organizations onboard from day one. TradeLens was wound down in early 2023, and Food Trust followed the same trajectory. IBM nonetheless kept its IP titles even after abandoning these products.
| Player | Issued US blockchain patents | Status |
|---|---|---|
| Advanced New Technologies (Ant Group) | 1,300+ | Global leader, non-US based |
| IBM (pre-deal) | 790 | Transferred to Circle |
| Circle (post-acquisition) | n/a (≥790) | US #1 |
| Bank of America | ~200 | US #2 |
Circle does not unseat the global record, which still belongs to Advanced New Technologies, the IP vehicle tied to Ant Group, with more than 1,300 patents. But the firm secures pole position on US soil.
A defensive shield against patent trolls
Beyond operational use, the deal serves a defensive purpose. According to the Crypto Open Patent Alliance (COPA), nearly 58% of US crypto patent litigation originates from NPEs — shells that run no product and live off licensing and litigation. Owning a large portfolio of prior art provides bargaining power against such attacks.
Circle had already taken precautions: its first patent — covering parallel blockchain data processing — dates to December 2023, and the firm joined the LOT Network, a coalition that protects members from patent assertion entities (PAEs). Circle did not disclose whether the IBM portfolio will join that defensive framework, nor how many US-issued titles were exactly included. IBM likewise did not state whether it retained licensing rights on any patents.
Arc, USDC and Circle National Trust: Circle’s full-stack offensive
The timing is deliberate. The Arc blockchain, designed for stablecoin finance, opened its testnet in fall 2025 with BlackRock, Visa and Goldman Sachs on board. The ARC token presale raised $222 million, including $75 million from a16z, at a fully diluted valuation of $3 billion. The Arc mainnet beta is slated for summer 2026.
On the payments side, USDC continues to dominate. In June 2026, the stablecoin processed $1,210 billion in adjusted volumes — roughly two-thirds of total stablecoin activity and more than double Tether’s USDT at $573 billion. USDC’s circulating supply sits around $74 billion.
Circle also secured OCC approval in July 2026 to establish Circle National Trust, a national digital trust bank that will provide digital asset custody services for Circle, its affiliates and institutional clients.
Market reaction and outlook
Markets read the announcement as constructive. CRCL shares closed +3.7% on Monday July 27, after already gaining +2.5% in pre-market trading earlier in the week. Over the medium term, the deal lets Circle align three assets — intellectual property, bank-grade infrastructure and a stablecoin stack — at a moment when competition in onchain payments is intensifying.
Conclusion
By buying nearly 1,000 patents from IBM, Circle is doing more than bolstering its product roadmap: it is building a legal fortress around the US stablecoin ecosystem just as NPEs increasingly target crypto firms. Combined with the OCC charter and the imminent launch of Arc, the acquisition sets an aggressive trajectory for the next twelve months — provided Arc’s beta mainnet delivers and the technical integration of the IBM portfolio goes smoothly.
