Case Timeline

II. Technology and Patent(s)-in-Suit Analysis

U.S. Patent No. 6,963,866 - "Method of Obtaining an Electronically Stored Financial Document," issued November 8, 2005.

The Invention Explained

• Problem Addressed: The patent describes the process of storing and retrieving electronic financial documents as "resource intensive, time consuming, and expensive," particularly when a client requests older documents that "require more resources and time to locate and retrieve" (Compl. ¶10; ’866 Patent, col. 1:54-63). Conventional systems were allegedly deficient because they lacked a direct interface inter-linked with off-site storage systems, preventing the efficient outsourcing of this "back office production" (Compl. ¶11; ’866 Patent, col. 2:8-18).
• The Patented Solution: The invention provides a method where financial documents are stored in one of two systems—an on-site system or a remote, off-site system—based on a "specific document parameter," such as the document's record date, relative to a predetermined threshold ('866 Patent, col. 4:40-52). When a user requests a document, a processing unit compares the document's parameter to the threshold and automatically accesses the correct storage system for retrieval, as illustrated in the patent's flowcharts ('866 Patent, col. 2:55-3:9; FIG. 2). This structure is intended to reduce the financial institution's back-office burden by enabling the outsourcing of retrieval for older documents ('866 Patent, col. 2:21-34).
• Technical Importance: The method provided a technical framework for financial institutions to implement a hierarchical storage management (HSM) system tailored to financial document retrieval, aiming to lower operational costs. (Compl. ¶11).

Key Claims at a Glance

• The complaint asserts independent claim 1. (Compl. ¶22).
• The essential elements of independent claim 1 include:
  • Storing a plurality of financial documents in a first fixed medium at a first storage system (remotely-located from a second) when a specific document parameter is greater than a predetermined parameter.
  • Storing a plurality of financial documents in a second fixed medium at the second storage system when the parameter is less than or equal to the predetermined parameter.
  • Utilizing a computer terminal connected to both storage systems through a processing unit.
  • Receiving and inputting a request for a document.
  • Comparing the requested document's parameter to the predetermined parameter.
  • Automatically accessing the first storage system if the parameter is greater than the threshold.
  • Automatically accessing the second storage system if the parameter is less than or equal to the threshold.
  • Retrieving the requested document from the appropriate fixed medium.
• The complaint does not explicitly reserve the right to assert dependent claims.

U.S. Patent No. 7,552,118 - "Method of Obtaining an Electronically Stored Financial Document," issued June 23, 2009.

The Invention Explained

• Problem Addressed: As a continuation of the '866 Patent, the '118 Patent addresses the same problem: the high cost and inefficiency for financial institutions in retrieving electronically stored documents, especially from separate on-site and off-site systems. ('118 Patent, col. 2:1-20).
• The Patented Solution: The '118 Patent describes a nearly identical solution involving a method to obtain documents from a first (remote) and second (on-site) storage system. The system stores documents in a tiered fashion based on a "specific document parameter" (e.g., age) relative to a "predetermined parameter" and uses a processing unit to compare the parameters and access the correct system upon receiving a request. ('118 Patent, Abstract; col. 2:38-3:15).
• Technical Importance: This patent continues the same technical theme of creating an efficient, automated, and partially-outsourceable document retrieval architecture for financial institutions. (Compl. ¶14).

Key Claims at a Glance

• The complaint asserts independent claim 1. (Compl. ¶31).
• The essential elements of independent claim 1 are substantively identical to claim 1 of the '866 Patent, including the steps of storing documents in different systems based on a parameter comparison (> or ≤ a threshold), utilizing a terminal and processing unit, comparing the parameter, automatically accessing the correct system, and retrieving the document.
• The complaint does not explicitly reserve the right to assert dependent claims.

U.S. Patent No. 7,836,067 - "Method of Obtaining Electronically-Stored Financial Documents," issued November 16, 2010.

• Patent Identification: U.S. Patent No. 7,836,067, "Method of Obtaining Electronically-Stored Financial Documents," issued November 16, 2010. (Compl. ¶15).
• Technology Synopsis: The patent discloses a method for obtaining financial documents from one of two different storage systems where documents are stored as electronic images. The storage logic is based on whether a document's specific parameter is less than a predetermined parameter (stored in the first system) or greater than or equal to it (stored in the second system). (Compl. ¶41, ¶42; ’067 Patent, Abstract). This logic is inverted relative to the '866 and '118 patents.
• Asserted Claims: The complaint asserts independent claim 53. (Compl. ¶40).
• Accused Features: The accused features are part of Guaranty's Online Banking system, which allegedly stores recent documents (e.g., less than 24 months old) in one system and older documents in a separate archival system, retrieving them based on a date comparison. (Compl. ¶41-¶45).

U.S. Patent No. 9,141,612 - "Method of Obtaining an Electronically Stored Financial Document," issued September 22, 2015.

• Patent Identification: U.S. Patent No. 9,141,612, "Method of Obtaining an Electronically Stored Financial Document," issued September 22, 2015. (Compl. ¶18).
• Technology Synopsis: This patent describes a method for accessing images of financial documents from one of two different storage systems. Documents are stored based on a specific document parameter (defined as a numerical sequence including a record date) being greater than, or less than or equal to, a predetermined parameter that includes a pre-selected numerical record date. (Compl. ¶51, ¶52, ¶54; ’612 Patent, Abstract).
• Asserted Claims: The complaint asserts independent claim 1. (Compl. ¶50).
• Accused Features: The infringement allegations target Guaranty's Online Banking system, which is accused of storing images of online statements and check images in separate systems based on date and using a processor to compare a requested date to a predetermined date to retrieve the corresponding image. (Compl. ¶51-¶55).

III. The Accused Instrumentality

Product Identification

The accused instrumentality is Defendant Guaranty's "Online Banking system." (Compl. ¶22).

Functionality and Market Context

The complaint alleges that the Online Banking system performs a method of tiered document storage and retrieval. It allegedly stores online statements and check images in "remotely located, separate storage systems based on the date associated with that document" (Compl. ¶22). Specifically, online statements for up to 24 months are stored in one system, while statements older than 24 months are transferred to a separate "storage system for archival and retrieval purposes" (Compl. ¶23). When a user requests a statement, the system allegedly compares the requested date range to the 24-month threshold and its "processing unit automatically accesses, and then retrieves, online statements from one storage system" or the other based on this comparison (Compl. ¶26). The complaint provides no specific allegations regarding the product's market share or commercial importance, other than that it is part of Guaranty's "full range of banking services." (Compl. ¶5). No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

'866 Patent Infringement Allegations

'118 Patent Infringement Allegations

Identified Points of Contention

• Scope Questions: A central question will be whether the Defendant's "retrievable" and "archival" storage systems meet the claim limitation of being "remotely-located" from one another. The complaint makes this allegation conclusorily (Compl. ¶22), and its factual basis (e.g., geographic separation vs. mere logical separation) will be a primary focus of discovery and argument.
• Technical Questions: A significant potential dispute arises from the complaint's own allegations. The claims require "automatically accessing" the appropriate storage system and "retrieving" the document. However, the complaint alleges that for statements older than 24 months, the "requester receives notification that customer service must be contacted" (Compl. ¶25, ¶34). This suggests a manual intervention step that may contradict the "automatically accessing" and "retrieving" limitations for the first/archival storage system, raising a key factual and technical question about how the accused system actually operates for older documents.

V. Key Claim Terms for Construction

The Term: "automatically accessing"

• Context and Importance: This term is critical because the complaint alleges both automatic access (Compl. ¶26) and a requirement to contact customer service for older documents (Compl. ¶25), creating an apparent contradiction. The definition of "automatically" will determine whether a process that may require human intervention at the user's end can still infringe.
• Intrinsic Evidence for a Broader Interpretation: A party could argue that "automatically" refers to the action of the "processing unit" itself after it receives a valid, processed request, not the entire end-to-end user experience. The patent states the "processing unit is utilized to automatically access one of the storage systems" ('866 Patent, col. 2:62-64), which could be interpreted to mean the machine-level action is automatic, regardless of preceding manual steps.
• Intrinsic Evidence for a Narrower Interpretation: A party could argue that the term, in the context of the patent's stated goal to reduce "back office production" and create an "efficient" system ('866 Patent, col. 2:21-23), implies a seamless process without intervention. The flowcharts (e.g., '866 Patent, FIG. 4) depict a machine-driven workflow after the request is entered, which could support an interpretation that a required call to customer service breaks the claimed automation.

The Term: "remotely-located"

• Context and Importance: This term is fundamental to the claimed two-system architecture. The infringement case depends on proving the Defendant's two alleged storage systems are "remotely-located."
• Intrinsic Evidence for a Broader Interpretation: The specification discusses outsourcing responsibility for document retrieval to a "third party entity" ('866 Patent, col. 3:17-18). A party might argue that "remotely-located" can therefore mean logically or administratively separate (i.e., controlled by another entity), not necessarily geographically distant.
• Intrinsic Evidence for a Narrower Interpretation: The patent consistently uses the "on-site" and "off-site" dichotomy throughout the specification and figures ('866 Patent, Abstract; col. 4:40-44; FIG. 1). Practitioners may focus on this language to argue that "remotely-located" was intended to mean physically and geographically separate from the financial institution's primary premises, which is the ordinary meaning of "off-site."

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement for all four patents. The allegations are based on the defendant providing customers with its Online Banking system and the "access to, support for, training and instructions" that allegedly "enable them to infringe" (e.g., Compl. ¶27, ¶36, ¶46, ¶56).
• Willful Infringement: The complaint's Prayer for Relief seeks trebled damages for willful infringement (Prayer for Relief, D). However, the body of the complaint does not set forth specific factual allegations to support willfulness, such as pre-suit knowledge of the patents-in-suit. The allegations of intent are made only "upon information and belief" in the context of inducement.

VII. Analyst’s Conclusion: Key Questions for the Case

• A central evidentiary question will be one of operational reality vs. claim language: Does the accused system's alleged requirement for customer service intervention to retrieve documents older than 24 months create a fatal mismatch with the claim requirement of "automatically accessing" and "retrieving" from the archival storage system?
• The case will also turn on a question of definitional scope: Can Plaintiff prove that the accused "retrievable" and "archival" systems are "remotely-located" as that term is construed in light of the patent's consistent "on-site" versus "off-site" framing? The factual evidence regarding the physical and logical architecture of Defendant's systems will be dispositive.
• A further point of analysis will be the variation in claim logic: For the '067 patent, which recites an inverted storage logic compared to the other patents, a key question will be whether the accused system's architecture can be mapped to this specific claim structure or if the allegations for this patent represent an instance of inconsistent pleading.
