Patent Value

• Patents are less central to payments competitive moat than network effects (merchant acceptance + cardholder base)
• But patent portfolios deter new entrants and support cross-licensing negotiations
• Significant patent battles between PayPal and banks over digital wallet implementations.

The Fundamental Challenge

• Alice Corp. v. CLS Bank (S.Ct. 2014): intermediated settlement = abstract idea
• Adding generic computer implementation adds nothing

Financial Calculations

• Risk scoring
• Interest calculation
• Currency conversion
• Fraud detection by rule — all potentially abstract ideas

Bad

• 'a method comprising receiving payment data
• Replacing with token
• Transmitting token to merchant'
• Alice killed this

Better

• 'a method comprising: receiving, via a hardware security module (HSM), a primary account number (PAN) encrypted with a first key
• Generating a cryptographically distinct token by applying a format-preserving encryption algorithm (AES-FF3-1) using a second key isolated to the HSM
• The token indistinguishable from a valid PAN without access to the second key
• Binding the token to a specific device fingerprint derived from [specific hardware attestation]
• Such that the token is invalid if device fingerprint mismatches by more than X bits'

Network Architecture Specificity

• Describe specific network topology
• Protocol
• Message format interactions

Measurable Improvement

• Claims that specify a measurable technical improvement — specific percentage reduction in fraud
• Specific latency improvement
• Specific reduction in false positives — are stronger

Recent Favorable Decisions

• Enfish (2016): database software that improved computer functionality = patent eligible
• McRO (2016): specific rules producing specific output from animation data = patent eligible
• CardioNet (Fed. Cir. 2019): ECG monitoring with specific detection algorithm = patent eligible

What is Still at Risk

• Generic fraud detection algorithms without specific hardware/architecture tie
• Pure algorithmic trading without specific order management system integration
• Abstract yield optimization without specific parameter constraints

Alice Step Two — Inventive Concept

• If abstract, survives if there is an inventive concept beyond generic computing
• A specific ML architecture (gradient boosted trees with specific feature engineering pipeline) + a specific inference latency requirement (sub-50ms for real-time auth) = potentially inventive concept.

• Block (formerly Square; Bitcoin Lightning patent applications; Cash App Bitcoin on-ramp)
• IBM (enterprise blockchain; Hyperledger Fabric contributions + related patents)
• MasterCard (500+ cryptocurrency-related applications including CBDC transaction processing)

Key Management

• Plaid (1,000+ applications; bank connection; account verification; transaction categorization)
• Yodlee/Envestnet
• MX Technologies
• Finicity (acquired by Mastercard)
• Akoya (bank-owned competitor)

Blockchain Patent Eligibility

• Anchor claims in specific consensus protocol steps
• Specific cryptographic hash chain structure
• Specific smart contract execution environment

Favor Patents When

• Specific novel user interaction flow that can be observed by reverse engineering
• Specific cryptographic protocol for transaction security
• Specific hardware integration for biometric payment authorization

When to File Provisionals

• Before launching beta products (public use bar)
• Before fundraising if you will publicly present novel technology
• Before any banking/partnership pilots that involve technical disclosure

Method Claims

• Specific transaction processing steps
• Specific data aggregation methods

Design Patents

• UI design patents protect novel payment interfaces faster (14 months) + at lower cost ($2,000-4,000)
• Protect the visual checkout flow
• Biometric authorization UI

Payment Network Patents

• Visa + Mastercard have extensive patent estates on token management

• Any new payment product should FTO against their published patent portfolios

Regulatory Patent Strategy

• BANKING-AS-A-SERVICE (BaaS): Bancorp
• Synapse
• Green Dot
• Cross River Bank have patents on the bank API middleware stack

Offensive Strategy

• Build patent portfolio to enable cross-licensing conversations with banks when they threaten
• Having patents gives you something to trade
• Defensive publication is also useful (prevent competitors from patenting broad categories before you can file).
