II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 7,519,551 - Systems and methods for administering return sweep accounts
The Invention Explained
- Problem Addressed: The patent addresses the technical and logistical challenges of implementing large-scale deposit sweep programs designed to offer enhanced FDIC insurance (Compl. ¶26, 28). Such systems must efficiently manage thousands of individual client accounts, distribute funds to aggregated deposit accounts across multiple banks, and handle high volumes of daily transactions without burdensome processing loads (Compl. ¶26).
- The Patented Solution: The invention is a computer-implemented method that uses an electronic database to manage a plurality of FDIC-insured, interest-bearing aggregated deposit accounts held at different banking institutions (Compl. ¶30). The system administers transfers from client accounts to these aggregated accounts, with a specific rule for transferring funds for high-balance clients to accounts at different banks to maintain FDIC coverage (Compl. ¶30(c); ’551 Patent, col. 6:1-12). Critically, it describes a method for effecting more than six withdrawals from an aggregated account in a month while "preserving an insured and interest-bearing status" of that account, circumventing regulatory limitations on savings-type accounts (Compl. ¶30(d)).
- Technical Importance: The claimed method provided a technological solution that reduced computer processing time and increased the efficiency of fund transfers, making large-scale enhanced insured deposit programs technically feasible and efficient (Compl. ¶29).
Key Claims at a Glance
- The complaint asserts at least independent Claim 1 (Compl. ¶146).
- Essential elements of Claim 1 include:
- Maintaining a plurality of FDIC-insured and interest-bearing aggregated deposit accounts, each held in a different bank.
- Maintaining an electronic database with information on funds held by each client in the aggregated accounts.
- Administering the aggregated accounts to transfer client funds, with a specific provision to move funds of clients exceeding a balance threshold to an aggregated account in a different one of the banking institutions.
- Withdrawing client funds from an aggregated deposit account more than six times a month while preserving the account's insured and interest-bearing status.
- Updating the electronic database based on these transfers and withdrawals.
U.S. Patent No. 7,933,821 - Systems and methods for administering return sweep accounts
The Invention Explained
- Problem Addressed: The patent addresses the inefficiency of prior art systems in managing large databases to allocate substantial funds among multiple banks while correctly calculating capacity, insurance coverage, and interest for individual client funds held within aggregated accounts (Compl. ¶33).
- The Patented Solution: The invention is a computer-implemented method that improves upon earlier systems by explicitly claiming the step of "allocating" client funds among more than one aggregated deposit account to ensure funds are maintained across different institutions (Compl. ¶32(c)). The method uses electronic databases containing both client account information and aggregated deposit account information to perform this allocation, determine when withdrawals exceed the six-per-month regulatory limit, and update the database accordingly (Compl. ¶32; ’821 Patent, col. 5:49-6:21). The complaint also highlights asserted dependent claims that add functionality for distributing interest and accessing data from various electronic payment systems like ACH and debit cards (Compl. ¶¶34-37).
- Technical Importance: This method's use of inventive database structures and an explicit allocation step allegedly made the distribution of client funds faster and more efficient, improving the overall function of computerized deposit sweep systems (Compl. ¶33).
Key Claims at a Glance
- The complaint asserts independent Claim 19 and dependent Claims 21, 24, and 25 (Compl. ¶176).
- Essential elements of Claim 19 include:
- Maintaining or accessing an electronic database with client account information.
- Maintaining or accessing a database with aggregated deposit account information for accounts held in a plurality of banks.
- Allocating, by computer, client funds among more than one aggregated deposit account so that portions are maintained in different banking institutions.
- Determining, by computer, client funds to be withdrawn from an aggregated account more than six times a month while preserving the account's insured and interest-bearing status.
- Updating the database based on the allocation of funds.
U.S. Patent No. 8,311,916 - Systems and methods for administering return sweep accounts
- Technology Synopsis: This patent discloses a method for managing funds in a multi-bank sweep program, enabled by an inventive database structure comprising both aggregated account information and client account information (Compl. ¶42). A key step is "allocating" customer funds to enough banks to provide enhanced FDIC insurance coverage, and then generating instructions to transfer funds to or from the aggregated accounts, including instructions for making more than six withdrawals a month while maintaining the accounts' insured status (Compl. ¶40).
- Asserted Claims: At least Claim 1 (Compl. ¶205).
- Accused Features: The complaint alleges that TD Ameritrade’s FDIC Insured Deposit Account program practices the claimed method by accessing databases to allocate client funds among multiple depository institutions (Compl. ¶¶213, 219).
U.S. Patent No. 7,509,286 - Systems and methods for money fund banking with flexible interest allocation
- Technology Synopsis: This patent addresses the technical challenge of providing flexible, tiered interest rates to clients whose funds are commingled in aggregated deposit accounts across multiple institutions (Compl. ¶43). The invention is a method for calculating a respective interest rate for each client's funds "independent from the respective client account pro rata share in earnings posted" to the aggregated account, allowing interest to be based on factors like the client's total balance (Compl. ¶¶44, 46).
- Asserted Claims: At least Claim 1 (Compl. ¶234).
- Accused Features: The complaint alleges infringement by TD Ameritrade’s FDIC Insured Deposit Account program, which offered clients tiered interest rates determined by TD Ameritrade based on the client's balance of funds (Compl. ¶¶110, 116).
U.S. Patent No. 7,680,734 - Money fund banking system
- Technology Synopsis: This patent addresses the technical challenge of facilitating client control over funds while minimizing electronic transfer activity (Compl. ¶51). The solution is a computerized method that involves "netting" a client's daily deposits and withdrawals to determine a single net transaction, and then determining whether to deposit or withdraw that net amount from the aggregated deposit account (Compl. ¶¶53, 55). This method is claimed in combination with features for handling debit card withdrawals and making more than six withdrawals a month via an intermediate bank (Compl. ¶53).
- Asserted Claims: At least Claims 1, 5, 8, 12, 15, and 16 (Compl. ¶265).
- Accused Features: The complaint alleges that TD Ameritrade’s program determined net transactions from client deposits and withdrawals to determine fund movements to and from aggregated accounts (Compl. ¶¶137, 281), and also administered withdrawals made by debit card (Compl. ¶136).
III. The Accused Instrumentality
Product Identification
- TD Ameritrade's FDIC Insured Deposit Account program ("the Program"), identified as a cash sweep program for brokerage account clients (Compl. ¶¶75, 77).
Functionality and Market Context
- The Program is alleged to be the primary and default cash sweep vehicle for TD Ameritrade brokerage accounts (Compl. ¶¶77, 103). Functionally, it is alleged to automatically sweep uninvested cash from a client's brokerage account into one or more FDIC-insured, interest-bearing "Master Accounts" established at a network of affiliated and third-party "Program Banks" (Compl. ¶¶79, 87, 96). This structure allegedly allows the Program to offer clients enhanced FDIC insurance by distributing their funds across multiple institutions, with deposits up to $247,500 per depositor in each Program Bank (Compl. ¶¶87, 93, 111). TD Ameritrade allegedly offers tiered interest rates on these accounts, with rates varying based on the client's asset level (Compl. ¶116). A screenshot from TD Ameritrade's website displays a table of 'FDIC Insured Deposit Account Rates-Core' effective October 5, 2018, showing different interest rates for different dollar ranges of assets (Compl. p. 41). The complaint alleges the Program generated over $3 billion in fee revenue from 2016 to 2018 (Compl. ¶76).

Identified Points of Contention:
- Scope Questions: A potential issue for the ’821 patent is the scope of the term "allocating." The analysis may question whether the Defendant's alleged system of transferring funds to third-party banks only when a threshold is met (Compl. ¶193) constitutes an "allocation...among more than one" account as required by the claim, or if it is merely a sequential overflow system that falls outside the claim's scope.
- Technical Questions: A central technical question for both the ’551 and ’821 patents is how the accused system achieves more than six withdrawals per month while "preserving an insured and interest-bearing status" of the aggregated accounts (Compl. ¶¶95, 194). The complaint makes this conclusory allegation, but the specific mechanism used by the accused system to circumvent federal banking regulations (e.g., Regulation D) will be a critical factual issue for infringement.
V. Key Claim Terms for Construction
The Term: "preserving an insured and interest-bearing status"
(appearing in ’551 Patent, Claim 1 and ’821 Patent, Claim 19)
- Context and Importance: This term is critical because federal banking regulations (such as Regulation D) historically limited the number of convenient withdrawals from interest-bearing savings or money market accounts to six per month. Exceeding this limit could cause the account to be reclassified as a non-interest-bearing transaction account. The patents claim to solve this problem. The infringement dispute may turn on whether the accused system's method for handling more than six withdrawals performs the specific function of "preserving" the account status in the manner contemplated by the patent.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The plain language of the claims does not specify how the status is preserved, which may support a construction covering any technical method that achieves this result without reclassifying the account.
- Evidence for a Narrower Interpretation: The specifications of the patents-in-suit and their family members may disclose specific mechanisms for achieving this, such as using a paired demand deposit account (DDA) for withdrawals or routing them through an intermediate bank (Compl. ¶53). A party may argue the term should be construed as limited to the specific embodiments disclosed.
The Term: "allocating"
(appearing in ’821 Patent, Claim 19 and ’916 Patent, Claim 1)
- Context and Importance: This term distinguishes later patents like the ’821 from the earlier ’551 patent by introducing a more active fund management step. Practitioners may focus on this term because the infringement analysis will question whether the accused system's simple transfer of "excess" funds to third-party banks (Compl. ¶193) meets the definition of "allocating...among more than one" account, or if the term requires a more sophisticated, simultaneous, or rule-based distribution of funds.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim requires allocating "among more than one" of the aggregated accounts. This could be interpreted broadly to cover any process that results in funds being purposefully placed in at least two different aggregated accounts to manage FDIC exposure.
- Evidence for a Narrower Interpretation: The specification may describe a more complex allocation process, for example, one that optimizes fund placement based on bank capacity or other rules beyond a simple overflow trigger. A party could argue the term is limited to such an algorithmic distribution process.
VI. Other Allegations
- Indirect Infringement: The complaint alleges that parent entities TDA, TDHC, and Schwab induced infringement by their operating subsidiaries (TDAC, TDATC, and Scottrade) by, for example, "encouraging its broker-dealers to sell and/or offer to sell" the accused FDIC Insured Deposit Account products (Compl. ¶¶148-149, 178-179, 236-237, 267-269). These allegations are predicated on Defendants' alleged knowledge of the patents-in-suit.
- Willful Infringement: Willfulness is alleged based on Defendants' purported pre-suit knowledge of the patents and the underlying technology (Compl. ¶¶171, 200, 229, 260, 286). The complaint alleges this knowledge stems from business discussions with Plaintiff's affiliate beginning in 2004, and from a 2008 confidential bidding process where Defendants allegedly received detailed technical information about the patented systems and then launched a similar product without a license (Compl. ¶¶68, 72, 150).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of technical mechanism: Does TD Ameritrade's system for processing more than six withdrawals per month from its sweep accounts utilize the same or an equivalent method for "preserving an insured and interest-bearing status" as that which is disclosed and claimed in the patents, or is there a fundamental mismatch in technical operation?
- A key question of claim construction will be the scope of the term "allocating." Can the term, as used in the ’821 and ’916 patents, be construed to cover a system that transfers funds to secondary banks only after a balance threshold is exceeded, or is it limited to a more complex, multi-factor distribution algorithm?
- A significant evidentiary battle may center on willfulness and intent: What evidence will emerge from the alleged 2008 confidential bidding process, and will it support the narrative of deliberate copying, potentially exposing Defendants to enhanced damages, or will it show that the accused system was independently developed?
