Circle Becomes Top U.S. Blockchain Patent Holder Following Massive IBM IP Acquisition

Stablecoin issuer Circle has jumped to the top position in U.S. blockchain intellectual property holdings after acquiring IBM’s extensive global patent library, the company announced on July 27.

The acquisition transfers more than 680 patent families and roughly 1,000 issued patents to Circle. Although financial terms of the transaction were not made public, the agreement instantly reshapes the competitive landscape for cryptographic infrastructure patents in the United States.

Data from patent analytics firm PatSnap showed that IBM held 790 U.S. blockchain patents by December 2025, topping all other American corporate filers, with Bank of America trailing in second place at approximately 200 patents. Before this transaction, Circle’s proprietary portfolio was nearly non-existent, having secured its initial patent only in December 2023 for parallel blockchain data processing methods.

The newly acquired IP encompasses foundational ledger architecture, enterprise cloud operations, supply chain verification, banking systems, and automated financial transaction frameworks. Circle plans to integrate these patents across its flagship stablecoin USDC, the Circle Payments Network, and Arc—its purpose-built blockchain dedicated to institutional settlement.

The portfolio will also support Circle’s development of agentic financial tools, which deploy autonomous software agents capable of executing complex financial tasks without manual oversight.

Sarah Wilson, General Counsel and Corporate Secretary at Circle, stated that intellectual property remains essential for accelerating the adoption of onchain infrastructure, noting that IBM’s long-standing research enhances Circle’s capability to build global, internet-native financial networks.

Prior to absorbing IBM’s intellectual property, Circle sought protection against predatory litigation through membership in the LOT Network, a corporate alliance structured to prevent patent assertion entities from suing member organizations. Acquiring IBM’s assets gives Circle significant defensive counter-weight and potential licensing leverage across the broader fintech industry.

The IP transfer comes amid evolving strategic dynamics between the two firms. IBM remains an active participant in Open Standard, the consortium behind Open USD—a yield-sharing stablecoin created to directly compete with USDC. Launched on June 30 with support from major institutions including BlackRock, Visa, Mastercard, and Coinbase, Open USD diverts reserve interest directly to network distributors rather than retaining interest income, directly challenging the yield capture model that supports Circle’s core revenue.

Following the announcement of the acquisition, shares of Circle (CRCL) gained 2.57% during Monday trading.
