The race for blockchain patents has intensified over the past decade, with major financial institutions positioning themselves at the forefront of innovation. Among them, Bank of America (BofA) stands out—not for launching blockchain-powered products, but for amassing one of the largest portfolios of blockchain and cryptocurrency-related patents in the world.
As of late 2018, BofA had filed over 50 patent applications tied to blockchain technology and digital currencies. This aggressive intellectual property strategy raises a critical question: Are these patents a sign of future adoption, or merely strategic positioning in a rapidly evolving financial landscape?
The Evolution of Bank of America’s Blockchain Patent Strategy
Bank of America's journey into blockchain innovation began in March 2014, when it filed its first patent related to cryptocurrency transactions. Though the term "blockchain" wasn't used in the initial application, the system described—a method for transferring funds between accounts using cryptographic currency—clearly relied on blockchain’s foundational principles.
By September 2015, the U.S. Patent and Trademark Office (USPTO) published this patent, titled "System for Using Cryptocurrency in Wire Transfers." This marked a milestone: possibly the first cryptocurrency-related patent held by a major retail bank globally.
That same month, BofA joined R3, a global consortium of banks and fintech firms collaborating on distributed ledger solutions. This move signaled early institutional interest in blockchain, even as public skepticism toward cryptocurrencies like Bitcoin persisted.

Between 2014 and 2015, BofA filed additional patents covering systems such as:
- Offline cryptocurrency storage
- Online custodial wallets
- Secure transaction validation
By January 2016, the bank announced plans to file more than 20 additional blockchain-related patents. Catherine Bessant, then Chief Operating Officer for Technology and Operations, stated in a CNBC interview:
“As a technologist, I find this technology fascinating. We’ve been trying to stay ahead of the curve… We already have around 15 patents, and I think most people would be surprised by how much we’ve done in blockchain and crypto.”
A Leader in Patent Volume—But Not Necessarily Implementation
Research by Marc Kaufman, chairman of the Blockchain Intellectual Property Committee at the U.S. Chamber of Commerce’s Global Innovation Policy Center, revealed that by mid-2018, Bank of America held approximately 45 active blockchain-related patents—more than tech giants like IBM and Alibaba, and far ahead of banking peers like Royal Bank of Canada (RBC), which held just eight.
Yet, despite this volume, no major blockchain-based product has launched under BofA’s brand.
This disconnect leads to an important distinction: filing patents is not the same as deploying technology.
Strategic Positioning vs. Real-World Adoption
While BofA invests heavily in blockchain R&D on paper, its public stance on cryptocurrencies remains cautious—if not outright skeptical.
In internal reports from early 2018, the bank acknowledged that digital assets pose a strategic risk to traditional banking models:
“Customers may choose to conduct business with other market participants or offer products in areas we view as speculative or risky—such as cryptocurrency.”
Moreover, BofA banned credit card purchases of cryptocurrencies, citing volatility and fraud concerns. Former employees have also questioned the practical value of the bank’s patent portfolio.
Michael Wuehler, a blockchain expert who worked at BofA for over 11 years (per his LinkedIn profile), tweeted in August 2018 that many of the bank’s blockchain patents—eight of which listed him as an inventor—were “meaningless” from a technical standpoint. He suggested they were filed more for public relations and brand perception than genuine innovation.
This aligns with a broader industry trend: patents as defensive tools. Companies file them to:
- Block competitors from entering certain technological spaces
- Attract investors by showcasing innovation capacity
- Monetize intellectual property through licensing
- Secure a first-mover image without committing to costly deployments
Key Areas Covered by Bank of America’s Blockchain Patents
Despite limited implementation, BofA’s patent filings reveal deep technical exploration across several critical domains:
🔐 Secure Private Key Storage
On October 30, 2018, USPTO confirmed a new patent focused on securing private cryptographic keys—the most vulnerable component in cryptocurrency ownership.
Current methods often store keys on internet-connected devices, making them susceptible to hacking. BofA’s proposed solution involves isolated storage mechanisms that detect tampering and prevent unauthorized access in real time.
🔄 Multi-Signature Digital Authentication
A September 2018 patent outlines a system for managing multi-party digital signatures within distributed networks. Designed with IoT (Internet of Things) environments in mind, it enables users to control which data gets shared with third parties—blocking or limiting transmission dynamically.
This could be applied beyond finance—for example, in supply chain tracking or smart home security.
✅ External Data Verification via Blockchain
Another patent explores using blockchain to verify external data sources, improving accuracy in assessing user financial health. By recording historical resource transfers on-chain, the system creates an immutable audit trail that enhances trust in automated lending or credit scoring systems.
🗃️ Blockchain-Based Data Storage with Access Control
Filed in April 2018 (originally submitted in October 2016), this patent describes a private blockchain system where individuals can securely store sensitive records—medical, financial, legal—and grant selective access to service providers.
For instance:
- A hospital accesses only medical history
- A lender sees only verified income data
- An insurer receives claims records without exposure to unrelated personal details
This model addresses key flaws in traditional data sharing (e.g., email attachments), where authenticity and integrity are hard to verify.
💱 Automated Cryptocurrency Exchange System
In December 2017, BofA secured a patent for a digital currency conversion platform that automatically exchanges one cryptocurrency for another based on real-time exchange rates pulled from external sources.
Such a system could streamline cross-border payments or enable dynamic treasury management—if ever deployed commercially.

Frequently Asked Questions (FAQ)
Q: Has Bank of America launched any blockchain products for customers?
A: As of 2025, Bank of America has not publicly launched any consumer-facing blockchain or cryptocurrency services, despite holding dozens of related patents.
Q: Why file so many patents if they’re not being used?
A: Patents serve strategic purposes beyond product development—they protect future options, deter competition, enhance corporate image, and may generate revenue through licensing.
Q: Does Bank of America support Bitcoin?
A: No. The bank has repeatedly criticized Bitcoin as speculative and volatile. It prohibits credit card purchases of crypto and does not offer direct crypto trading or custody services.
Q: Can patents expire?
A: Yes. Most utility patents last 20 years from filing. If maintenance fees aren’t paid or innovations aren’t commercialized, patents lapse and enter the public domain.
Q: Who benefits from unused patents?
A: Even unused patents can give companies leverage in legal disputes, partnerships, or mergers. They may also be sold or licensed later.
Q: Is Bank of America alone in this approach?
A: No. Many large banks and tech firms use similar strategies—filing broad patents to secure future options while waiting for regulation and market conditions to mature.
Conclusion: Innovation Theater or Long-Term Vision?
Bank of America's blockchain patent portfolio reflects a dual identity: technological ambition paired with institutional caution.
While it leads in patent volume, its reluctance to deploy real-world applications suggests that many of these inventions serve symbolic rather than functional roles—securing intellectual territory while waiting for regulatory clarity and market demand.
Nonetheless, should conditions shift—such as wider crypto adoption, clearer U.S. regulations, or competitive pressure from fintech disruptors—BofA’s patent arsenal could become a powerful launchpad for innovation.
For now, the message is clear: They’re not betting on blockchain yet—but they’re making sure they can when the time comes.
