Circle has bought nearly 1,000 blockchain patents from IBM, covering 680 patent families. The purchase includes most of IBM's blockchain patent business. The acquisition vaults Circle into the ranks of the top patent holders in the U.S. and internationally. The company says the intellectual property is critical for expanding onchain infrastructure adoption.
What Circle bought
The portfolio spans 680 patent families — roughly 1,000 individual patents. IBM had been building its blockchain patent library for years, filing on everything from distributed ledger consensus to smart contract execution. Circle now owns the bulk of that work. The exact terms weren't disclosed, but the deal closed this month.
Why the patents matter
Circle has been pushing to make onchain infrastructure more accessible. The company runs USDC, the second-largest stablecoin, and operates payment and settlement rails built on blockchain. Owning a deep patent library gives Circle legal cover to build without fear of infringement suits. It also lets the company license technology to others. Circle's leadership has said the IP is essential for the next phase of adoption — moving beyond crypto trading into real-world finance.
Circle's new patent position
Before the deal, Circle held a modest number of blockchain patents. Now it's one of the largest holders in the U.S. and globally. That puts it alongside other major patent accumulators like Alibaba and nChain. The move signals that Circle intends to be a long-term infrastructure player, not just a stablecoin issuer. It also gives the company leverage in any future patent disputes — a growing risk as blockchain tech moves into banking, supply chains, and government systems.
IBM has been scaling back its blockchain push for a while. The company still holds some patents, but selling the bulk of its portfolio to Circle effectively ends IBM's run as a major blockchain patent holder. For Circle, the next step is integrating the patents into its development roadmap. The company hasn't said whether it will license the IP broadly or keep it mostly for internal use. Either way, the deal reshapes the patent landscape in a market that's still sorting out who owns what.
