Circle acquires IBM's blockchain patent portfolio, claiming US market leadership

Circle has acquired what it describes as the fundamental assets from IBM’s blockchain patent portfolio, a transaction covering 680 patent families and nearly 1,000 issued patents globally. The deal positions Circle as, by its own account, the leading blockchain patent holder in the United States.

The timing is not incidental. Tokenisation activity has accelerated to the point where patent litigation is becoming financially worthwhile, a dynamic the source traces back to the 2018/2019 period when blockchain patent registrations surged but offensive enforcement remained rare. That equilibrium appears to be shifting: JPMorgan faced two patent claims last week, one directly targeting blockchain and one touching it indirectly, suggesting incumbents are now viable targets.

Whether Circle intends to use the portfolio offensively or defensively remains genuinely open. The announcement contains no pledge to limit use to defensive purposes, a contrast with Blockstream’s public stance and with the Crypto Open Patent Alliance (COPA), whose members including Block, Blockstream, Coinbase, and Strategy have committed to non-offensive use. Circle is not a COPA member. The likelier read, though not stated explicitly, is that the rationale may extend beyond both offensive and defensive use in the conventional sense, perhaps as a strategic asset in licensing, partnership negotiations, or the ongoing push toward institutional legitimacy.
