1:17-cv-09174
Mantissa Corp v. First Financial Corp
I. Executive Summary and Procedural Information
- Parties & Counsel:
- Plaintiff: Mantissa Corporation (Alabama)
- Defendant: First Financial Corporation and First Financial Bank, N.A. (Indiana)
- Plaintiff’s Counsel: Young Basile Hanlon & MacFarlane, P.C.; Hunter Taubman Fischer LLC
- Case Identification: 1:17-cv-09174, N.D. Ill., 12/20/2017
- Venue Allegations: Venue is alleged to be proper because Defendants have a regular and established place of business in the district, have conducted business in the district, and have committed the alleged acts of infringement in the district.
- Core Dispute: Plaintiff alleges that Defendants’ CardGuard mobile application and associated banking services, which allow customers to set controls on their debit cards, infringe a patent related to methods for controlling the use of a financial account.
- Technical Context: The technology at issue involves systems that give financial account holders direct, real-time control over how, when, and where their accounts can be used, primarily for preventing fraud and managing spending.
- Key Procedural History: The complaint highlights the prosecution history of the patent-in-suit, noting that the U.S. Patent and Trademark Office (USPTO) allowed the claims after the Supreme Court’s decision in Alice Corp. v. CLS Bank. The complaint states the USPTO found the applicant's arguments about improving conventional credit card technology to be "persuasive," an assertion seemingly intended to preemptively counter a patent-eligibility challenge under 35 U.S.C. § 101. The complaint also alleges Defendants had notice of the patent via a letter dated November 6, 2017, prior to the filing of the suit.

II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,361,658 - "System and Method for Enhanced Protection and Control Over the Use of Identity"
- Issued: June 7, 2016
The Invention Explained
- Problem Addressed: The patent’s background section describes traditional fraud protection methods as reactive, typically involving monitoring and after-the-fact notification, which fails to prevent the initial harm of identity misuse (’658 Patent, col. 1:51-63). It notes a need for a system that allows an identity owner to "proactively" control their identity information at a "fundamental level" (’658 Patent, col. 2:7-12).
- The Patented Solution: The invention is a method where a service provider controls transactions for a financial account based on rules set by the account owner via a network. The owner can define a "scope of use" including setting the account to ON or OFF, authorizing or unauthorizing transactions based on categories of transaction partners, and setting a geographical area for permitted use (’658 Patent, Abstract; col. 15:20-31). When a transaction is attempted, the system receives an inquiry, determines if it complies with the owner's rules, and responds to the source to permit or deny it (’658 Patent, col. 15:32-53).
- Technical Importance: The claimed method shifts control over transaction authorization from the financial institution to the end-user, enabling granular, real-time fraud prevention rather than relying on delayed detection (’658 Patent, col. 2:7-12; Compl. ¶15).
Key Claims at a Glance
- The complaint asserts claims 1-16, with independent claim 1 being a method claim (’658 Patent, col. 15:20-53; Compl. ¶31).
- The essential elements of independent claim 1 include:
- "setting scope of use, defined by the entity via a network, for the financial account, including at least:"
- "(a) the financial account to either OFF or ON;"
- "(b) for a plurality of individual categories, whether each category is authorized or unauthorized for transactions using the financial account, each category representing a different type of transaction partner; and"
- "(c) a geographical scope reflecting a geographic area in which transactions are authorized;"
- "receiving, via a network from a source other than the entity, an inquiry regarding a proposed transaction that would use the financial account;"
- "determining, relative to the scope of use, whether the financial account may or may not be used for the proposed transaction...; and"
- "responding to the inquiry by providing, via a network to the source, first information based on the result of the determining."
- "setting scope of use, defined by the entity via a network, for the financial account, including at least:"
- The complaint alleges infringement of dependent claims 2-16 but does not specify a separate infringement theory for them (Compl. ¶31).
III. The Accused Instrumentality
Product Identification
- Defendants’ "CardGuard" app and associated "products, systems, and services for debit and/or credit card control, monitoring, and management" (Compl. ¶23).
Functionality and Market Context
- The complaint alleges that the CardGuard app provides users with "Complete control" over their debit cards (Compl. ¶24). The specifically accused features, drawn from Defendants' marketing materials, include:
- An "instant ON/OFF Switch for your card" (Compl. ¶24, p. 7).
- The ability to "Control purchase types" by defining the "types of merchants where your card can be used" (Compl. ¶24, p. 7).
- The ability to "Set geographic limits for your card," which allows users to "restrict purchases to merchants within a certain range of your location" or by "city, state or zip code" (Compl. ¶24, p. 7).
- The ability to set spending limits and monitor family or employee card usage (Compl. ¶24, p. 7).
- The service is offered as a free, exclusive app for First Financial Bank customers with Apple or Android phones (Compl. ¶24).

Identified Points of Contention
- Scope Questions: The infringement analysis may raise the question of whether the term "transaction partner" in the patent can be construed to read on the "merchant types" feature of the accused product. Similarly, the relationship between the claimed "geographical scope" and the accused product's feature of setting a "range of your location" could be disputed.
- Technical Questions: The complaint's allegations are based on the user-facing features described in marketing materials. A key factual question will be how Defendants' backend systems technically implement these controls—specifically, how they receive, process, and respond to transaction inquiries from third-party sources and whether this process aligns with the steps recited in the method claim. The complaint's allegation of infringement "based on the actions of other entities attributable to Defendants" suggests that divided infringement may become an issue (Compl. ¶31).
V. Key Claim Terms for Construction
The Term: "transaction partner"
- Context and Importance: This term is critical for defining the scope of the "category" limitation in claim 1(b). The infringement allegation hinges on equating the accused product's "merchant types" (e.g., "grocery stores, gas stations") with the claimed "categories" of "transaction partner[s]." The breadth of this term will determine whether setting rules based on merchant category codes falls within the claim.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification provides an example of an identity owner setting rules to "deny requests from that store or type of store," which supports reading the term to include merchant categories (’658 Patent, col. 6:49-50).
- Evidence for a Narrower Interpretation: A defendant could argue that other examples in the patent, such as "pre-authorized for health services (e.g., doctors, hospitals, pharmacies)," imply a more specific, pre-vetted relationship than a generic merchant category (’658 Patent, col. 5:44-48).
The Term: "geographical scope"
- Context and Importance: This term from claim 1(c) is central to the geographic control feature. The accused product allegedly allows restricting purchases "within a certain range of your location," which is a dynamic, user-centered area, as well as by fixed areas like "city, state or zip code" (Compl. ¶24, p. 7). The construction will determine if a dynamic, mobile-based radius is equivalent to a more static, predefined "geographic area."
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim language is general, referring to "a geographic area in which transactions are authorized" without further limitation, which may support encompassing various ways of defining that area (’658 Patent, col. 15:33-34).
- Evidence for a Narrower Interpretation: The specification gives an example of "USA Only" as a geographic limit, suggesting the inventors may have contemplated fixed, predefined boundaries rather than a dynamic radius centered on a user's current location (’658 Patent, col. 13:1).
VI. Other Allegations
- Indirect Infringement: The complaint alleges inducement by Defendants instructing customers to download and use the CardGuard app to perform the allegedly infringing functions (Compl. ¶32). It also alleges contributory infringement, asserting that the accused products and their components are "especially made or adapted for use in an infringement of the claims" and are not staple articles of commerce suitable for substantial non-infringing use (Compl. ¶33-34).
- Willful Infringement: The willfulness allegation is based on Defendants’ alleged knowledge of the ’658 Patent from at least the date of a pre-suit notice letter sent on November 6, 2017, and their continued infringement after receiving that notice (Compl. ¶27, ¶29).
VII. Analyst’s Conclusion: Key Questions for the Case
- A primary issue will be one of patent eligibility: despite the favorable prosecution history cited by the Plaintiff, the court will have to determine whether the claims are directed to the abstract idea of managing financial risk, and if so, whether the specific combination of user-configurable rules (ON/OFF, category, geography) amounts to an inventive concept that transforms the idea into a patent-eligible technological improvement.
- A second core issue will be one of definitional scope: the infringement case will turn on whether the features of the accused CardGuard service, such as setting rules by "merchant type" and a dynamic "range of your location," fall within a proper construction of the patent's terms "transaction partner" and "geographical scope."
- A key evidentiary question will be one of system architecture: establishing infringement will require moving beyond the user-facing app features to show that Defendants' backend systems, potentially in concert with other entities in the payment processing chain, perform the specific "receiving", "determining", and "responding" steps as recited in the asserted method claims.
