II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 10,846,729 - "Intelligent Clearing Network"
The Invention Explained
- Problem Addressed: The patent’s background section describes the legacy process for paper coupons as slow, labor-intensive, and prone to fraud and disputes, which delayed retailer reimbursement and prevented timely collection of market data (’729 Patent, col. 1:38-62).
- The Patented Solution: The invention proposes a real-time network connecting a retailer’s point-of-sale (POS) terminal to a remote Intelligent Clearing Network (ICN) server (’729 Patent, col. 2:1-11). When a coupon is scanned at the POS, its data is transmitted to the ICN server for immediate validation and redemption, eliminating the need for manual clearing and settlement processes (Compl. ¶¶ 21-22; ’729 Patent, col. 2:23-31).
- Technical Importance: This approach provided a "convenient, fast, auditable, and comprehensive financial settlement process" for coupons, a significant change from the manual, paper-based systems it aimed to replace (Compl. ¶22).
Key Claims at a Glance
- The complaint asserts independent claim 10 (Compl. ¶45).
- Essential elements of claim 10 include:
- An ICN server with a processor and memory.
- The server is configured to:
- Receive first coupon/incentive information (including a UPC) from a remote retail terminal.
- Validate that information by comparison.
- Transmit redemption codes back to the terminal.
- Receive information about the successful redemption from a retail server.
- Determine if the redemption was valid based on the received information.
- Store the redeemed coupon information in a database.
- The complaint does not explicitly reserve the right to assert dependent claims for this patent.
U.S. Patent No. 9,070,133 - "Intelligent Coupon Network"
The Invention Explained
- Problem Addressed: The patent identifies inefficiencies in coupon processing, including the labor of manual clipping for consumers and manual clearing for businesses, as well as significant delays for manufacturers in receiving "critical information" and market intelligence from redemption data (’133 Patent, col. 1:11-34).
- The Patented Solution: The invention describes a system linking a "coupon card," which contains a unique account identifier, to coupon information stored in a centralized database (’133 Patent, col. 5:4-8). When the card is used at a POS terminal, the system can automatically process associated coupons and enable the "speedy dissemination of coupon redemption data to interested advertisers and manufacturers" (Compl. ¶28). The patent also describes that the card can be updated with new offers (’133 Patent, col. 3:61-4:6).
- Technical Importance: The system aimed to improve the speed and accuracy of coupon clearing while simultaneously accelerating the delivery of vital market intelligence from redemption events (Compl. ¶26).
Key Claims at a Glance
- The complaint asserts independent claim 1 (Compl. ¶61).
- Essential elements of claim 1 include operations stored on a computer-readable medium for:
- Receiving a "unique account identifier" at a coupon processing server from a POS terminal at a remote retail store where it was "scanned."
- In response, determining if a valid coupon is associated with that identifier in a database.
- If a valid coupon exists, transmitting an indication of that coupon back to the POS terminal.
- In response to receiving an indication of a redeemed coupon from the POS, updating the database and transmitting a confirmation to the associated manufacturer.
- The complaint does not explicitly reserve the right to assert dependent claims for this patent.
U.S. Patent No. 9,098,855 - "Intelligent Clearing Network"
Technology Synopsis
The complaint describes the ’855 Patent as relating to methods for the electronic processing of coupons and incentives via an intelligent clearing network (Compl. ¶34). The system uses "trigger and target universal product codes" transmitted over the network from a POS terminal to a remote server to automatically validate or reject a promotion and to communicate the redemption success or failure back to the manufacturer, thereby providing rapid market intelligence (Compl. ¶37).
Asserted Claims
Independent claim 53 is asserted, along with claims 32, 34, and 49 (Compl. ¶80).
Accused Features
The accused features include Quotient's platforms that receive product code information and promotion requests from retailer POS terminals, validate these requests at remote ICN servers, and send response messages back to the POS to authorize discounts (Compl. ¶¶ 82-85).
III. The Accused Instrumentality
Product Identification
The "Accused Products" are a collection of Defendant Quotient's services, including the Quotient Promotions Platform, Quotient Digital Promotions, Quotient Promotions Network, Quotient Consumer Properties (including Shopmium and Coupons.com), Omnichannel Platform, Quotient Analytics, and Retailer iQ (Compl. ¶40).
Functionality and Market Context
- The complaint alleges the Accused Products form a digital promotions architecture that uses master databases across remote data centers to manage coupon processing (Compl. ¶¶ 46, 62). This architecture, depicted in a diagram within the complaint, is described as serving "several million API calls per hour" from retailers' POS terminals (Compl. p. 16; Compl. ¶¶ 48, 63).
- Functionally, users "clip" digital coupons in applications like Coupons.com. When the user checks out at a retail store, they can provide a loyalty card or phone number at the POS terminal. The retailer's system then uses Quotient's services to "look up the user and the coupons clipped and gives instant discounts redeeming the coupons directly at the POS" (Compl. ¶¶ 49, 66).
- The complaint alleges this system provides Quotient's manufacturer clients with on-demand access to track purchases and promotion validations, thereby delivering analytics and performance tracking (Compl. ¶72).
IV. Analysis of Infringement Allegations
U.S. Patent No. 10,846,729 - Infringement Allegations
| Claim Element (from Independent Claim 10) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| An ICN server comprising a processor; and a memory including computer program code... | Quotient's Digital Promotions architecture uses master databases across datacenters that perform coupon processing and validation. | ¶46 | col. 53:41-44 |
| to receive, at an ICN server, first coupon or incentive information, including universal product code information... from a terminal in the retail business, the ICN server being at a location that is remote from the retail business | Quotient servers, hosted in remote data centers, receive API calls from retailers' POS terminals containing data associated with clipped coupons, including UPC information. | ¶49 | col. 53:45-51 |
| to validate, at the ICN server, the first coupon or incentive related information by performing a comparison of the first coupon or incentive related information based at least in part on the universal product code information | Quotient's service looks up the user and clipped coupons and performs "real time and batch processing of all coupon clips and redemptions" using a distributed cache and database. | ¶50 | col. 53:52-55 |
| to transmit from the ICN server, in response to validation... coupon or incentive codes... useable by the terminal to redeem the first coupon or incentive information | After validation, Quotient's service enables the retailer to give "instant discounts redeeming the coupons directly at the POS." | ¶51 | col. 53:56-62 |
| to receive, at the ICN server from a retail server located in a retail business... redeemed coupon related information indicating successful redemption of a coupon | After redemption at the POS, Quotient's servers receive redeemed coupon information, which includes product, customer, and retailer identification data. | ¶52 | col. 53:63-54:4 |
| in response to receiving the redeemed coupon related information, to determine whether the redemption of the coupon was valid based on the redeemed coupon related information | Quotient's system executes "complex business rules based on the date or count" and runs rate-limiting rules to validate redemptions. | ¶52 | col. 54:5-8 |
| to store, by the ICN server, the redeemed coupon related information in a redeemed coupon database... | Quotient stores transaction data for reconciliation and analytics in its MariaDB database. | ¶53 | col. 54:9-14 |
Identified Points of Contention
- Scope Questions: A central question may be whether the phrase "coupon or incentive information... input to a terminal," as used in the patent, can be construed to cover a scenario where a user's account (linked via loyalty card or phone number) is looked up by the POS system, which then automatically applies pre-selected digital offers. This differs from the patent's apparent focus on scanning a discrete coupon (e.g., via a GS1 barcode) at the terminal.
- Technical Questions: The complaint presents a high-level architecture diagram of the accused system (Compl. p. 16). A technical question will be how the distributed components of this "microservices architecture"—such as API gateways, caches, and multiple databases—map onto the more monolithic "ICN server" and "redeemed coupon database" recited in the claim.
U.S. Patent No. 9,070,133 - Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| A... computer-readable medium storing instructions executable by a processor to perform operations for processing coupons across a network | Quotient's Digital Promotions architecture uses master databases across its data centers to store instructions for processing coupons. | ¶62 | col. 11:57-59 |
| to receive at a coupon processing server, a unique account identifier from a first point of sale terminal via a network... where the unique account identifier was scanned at the first point-of-sale terminal which is located at a retail store | The complaint alleges that when a user provides a phone number or loyalty card at the POS, this acts as a "unique account identifier" that is received by Quotient's remote servers.

| in response to receiving... an indication of at least one redeemed coupon, updating the database of accounts and transmitting... to a manufacturer... an indication that the at least one redeemed coupon was redeemed against a purchased transaction | Quotient's Analytics Platform provides manufacturers "on-demand access" to track purchases and promotion validations, serving as a transmitted indication of redemption. | ¶72 | col. 12:12-22 |
Identified Points of Contention
- Scope Questions: A key dispute will likely concern whether a user's loyalty card ID or phone number constitutes the claimed "unique account identifier." The patent specification extensively describes this identifier in the context of a physical or digital "coupon card" (e.g., ’133 Patent, Figs. 8A, 8B).
- Technical Questions: The claim requires the unique account identifier to be "scanned at the first point-of-sale terminal." The complaint alleges this occurs when a user provides a loyalty card or phone number (Compl. ¶68). A factual question will be whether the technical means by which a loyalty account is accessed at a modern POS (e.g., card swipe, NFC tap, manual entry of a phone number) meets the claim's requirement of being "scanned" as understood in the patent's context.
V. Key Claim Terms for Construction
From the ’729 Patent
- The Term: "coupon or incentive information... input to a terminal"
- Context and Importance: The case may turn on whether this phrase covers modern digital couponing systems. Infringement depends on whether a POS system looking up a user's loyalty account and finding pre-clipped digital offers constitutes receiving "information... input to a terminal."
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The claim language itself is not explicitly limited to a specific method of input. The term "information" is broad and could encompass any data that initiates a coupon redemption process at the terminal.
- Evidence for a Narrower Interpretation: The patent specification repeatedly describes the input mechanism as reading data elements from a "GS1 barcode" (’729 Patent, col. 2:23-31; Abstract). This focus on a specific, scannable data carrier may support a narrower construction limited to direct scanning of a coupon representation.
From the ’133 Patent
- The Term: "unique account identifier... scanned at the first point-of-sale terminal"
- Context and Importance: This term is critical because the accused system relies on user identifiers like loyalty card IDs and phone numbers, not necessarily a dedicated "coupon card" that is scanned. Practitioners may focus on whether "scanned" has a narrow, optical meaning or a broader meaning that includes electronic lookups. The complaint's visual evidence shows a system diagram where transactions flow from the POS, but does not depict the act of scanning itself (Compl. p. 24).
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The term "scanned" is not explicitly defined in the patent. An argument could be made that any electronic reading of an identifier at a terminal (e.g., a magnetic stripe swipe of a loyalty card) constitutes a form of "scanning."
- Evidence for a Narrower Interpretation: The patent specification and figures consistently illustrate the concept in the context of a physical "coupon card" being presented and read (e.g., ’133 Patent, col. 7:3-6; Fig. 8A, step 816 "CONSUMER SLIDES ICN COUPON CARD"). This may suggest the "unique account identifier" is intended to be on such a card and that "scanned" refers to the act of reading that specific card.
VI. Other Allegations
- Indirect Infringement: For all three patents, the complaint alleges induced infringement. The basis for this allegation is that Quotient provides its Accused Products (including mobile applications like Shopmium and Coupons.com) and allegedly "encourages and instructs its customers and end users to obtain, install, configure, use, and activate" them in a manner that directly infringes the patent claims (Compl. ¶¶ 55, 75, 88).
- Willful Infringement: The complaint alleges that Quotient has had actual notice of the patents-in-suit and its alleged infringement since at least July 12, 2023, the date of a notice letter sent by the patent owner's chairman (Compl. ¶41). The allegation of continued infringement after this date forms the basis for the willfulness claim (Compl. ¶43; Prayer for Relief ¶C).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the term "coupon," as used in claims grounded in the context of discrete, scannable data carriers (like barcodes or coupon cards), be construed to cover modern digital offers that are linked to a user's account and applied automatically at checkout without the presentation of a distinct coupon instrumentality?
- A key evidentiary question will be one of functional interpretation: does the accused system's use of a loyalty card ID or phone number to look up a user's account meet the claim limitation of a "unique account identifier" that is "scanned at the first point-of-sale terminal," or is there a fundamental mismatch in the technical action performed at the point of sale?
- A third central question will be one of architectural mapping: can Plaintiff demonstrate that the complex, distributed "microservices architecture" of the Accused Products, as depicted in the complaint (Compl. p. 16, 29), maps onto the specific server, controller, and database elements recited in the more simplified system architecture of the patent claims?
