Two Patent Suits in Five Days Put JPMorgan's Tokenisation Stack Under Legal Pressure

JP Morgan has been named as defendant in two separate patent infringement actions filed within five days of each other, both targeting core components of its digital asset infrastructure. Nueces Blockchain LLC filed its complaint on 22 July, asserting three patents against Kinexys, JPMorgan’s permissioned Ethereum-based blockchain unit that processes billions of dollars in tokenised transactions daily. Anonos Innovations LLC followed with a second action targeting the bank’s merchant payment tokenisation infrastructure, a claim that also touches on distributed ledger technology applications beyond card payments.

The Nueces complaint is the broader of the two in potential reach. The patents are framed as covering foundational blockchain operations, and the complaint explicitly extends the alleged infringement beyond Kinexys to Coinbase‘s Base network, arguing that JPMorgan triggers liability each time a JPM Coin deposit token transaction it initiates is executed on Base. That framing, if it survives scrutiny, would implicate most blockchain architectures rather than Kinexys alone.

For institutions scaling tokenisation platforms, the week’s filings are a signal that patent assertion entities are now actively targeting enterprise blockchain infrastructure rather than treating it as an edge case. The Anonos action’s overlap with DLT applications means payment tokenisation programmes cannot be assessed in isolation from broader digital asset legal exposure. Both complaints are at the earliest stage of litigation and no findings have been made, but the dual filing pattern suggests coordinated pressure rather than opportunistic one-offs.
