  • Plaintiff’s Counsel: Rabicoff Law LLC
• Case Identification: 1:19-cv-02577, N.D. Ill., 04/16/2019
• Venue Allegations: Venue is alleged to be proper because Defendant is incorporated in Illinois and maintains its principal place of business within the Northern District of Illinois.
• Core Dispute: Plaintiff alleges that Defendant’s e-commerce website and associated systems infringe a patent related to an automated multimedia data processing network.
• Technical Context: The technology concerns interactive data processing systems designed to handle complex, personalized transactions between a remote user terminal and a central computer, originating from an era predating the modern internet.
• Key Procedural History: The complaint notes that the patent-in-suit, U.S. Patent No. 7,010,508, survived an ex parte reexamination at the USPTO, which confirmed the validity of the asserted claims (1-7 and 16-17) while cancelling others. The complaint also references the prosecution history, where the inventor distinguished the claimed invention from prior art based on on its novel hardware architecture and its use of "backward-chaining and forward-chaining" processing techniques to create a personalized user interaction, a point that was upheld by the Board of Patent Appeals and Interferences.

Case Timeline

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

U.S. Patent No. 7,010,508 - "Automated Multimedia Data Processing Network" (Issued Mar. 7, 2006)

The Invention Explained

• Problem Addressed: The patent describes that in the mid-1980s, self-service terminals were unable to handle complex transactions requiring significant interaction between individuals and institutions, such as processing a loan application (’508 Patent, col. 1:39-44). The complaint alleges that a key technical limitation of this prior art was data congestion caused by using a single, shared bus to handle all I/O functions, such as video playback and data communications, simultaneously (Compl. ¶ 11). The complaint provides Figure 8 from a prior art patent to illustrate this single-bus architecture (Compl. p. 6).
• The Patented Solution: The invention claims to solve this problem with a novel terminal ("station") hardware architecture featuring at least two independent information handling connections (’508 Patent, Fig. 2; Compl. ¶ 12). One connection manages high-bandwidth data like video, while a separate, independent connection—using a Direct Memory Access (DMA) unit—handles communications with a remote central processor, preventing system congestion (Compl. p. 7). This architecture enables the system to process a user's inputs "according to backward-chaining and forward-chaining sequences," which allows for a more dynamic and "individualized presentation" compared to the rigid "fixed menu tree" approach of the prior art (Compl. ¶ 9, p. 3).
• Technical Importance: This dual-path architecture is alleged to have enabled a higher level of interactivity and personalization for complex user transactions than was possible with the conventional terminal technology of the time (Compl. p. 7).

Key Claims at a Glance

• The complaint asserts direct infringement of at least Claim 1 (Compl. ¶ 17).
• Independent Claim 1 recites an "automated multimedia system for data processing" comprising, among other elements:
  • A "computerized installation" with a database.
  • At least one "station" with a general-purpose computer, mass memory, and video display.
  • "Means for communicating data" between the installation and the station.
  • "Means for selectively and interactively presenting... interrelated textual and graphical data" at the station.
  • "Means for interactively directing the operation" of the station, which includes "means for processing said operator-entered information... according to backward-chaining and forward-chaining sequences."
  • The installation has "means responsive" to the station to transmit data from its database.
• The complaint does not explicitly reserve the right to assert dependent claims, though this is common practice.

III. The Accused Instrumentality

Product Identification

The accused instrumentality is the Woodland Foods website (https://woodlandfoods.com), including its "login" and "My cart" functionalities, and its supporting and related systems (Compl. ¶ 2).

Functionality and Market Context

• The accused instrumentality is an e-commerce platform that allows customers to purchase food ingredients (Compl. ¶ 2). Its functionality includes allowing users to create accounts, sign into those accounts to retrieve information, browse products, add items to a shopping cart, and place purchase orders (Compl. ¶¶ 19, 27).
• The complaint alleges that the website's functionality and its supporting server, when accessed by a user's terminal (e.g., a computer with a web browser), create a system that practices the claimed invention (Compl. ¶ 19). The complaint alleges the Defendant's server places a "cookie" on the user's terminal to manage the shopping cart (Compl. ¶ 20). The complaint further alleges that the company has been actively developing and "launch[ing]" this e-commerce platform (Compl. ¶ 21).

IV. Analysis of Infringement Allegations

The complaint references a claim chart in an external exhibit (Exhibit H) that was not provided with the complaint document (Compl. ¶ 19). The narrative infringement theory alleges that the Defendant's system, comprising its web servers and the user's computer, meets the limitations of Claim 1 of the '508 Patent.

The plaintiff's theory appears to map the claimed "computerized installation" to the Defendant's web servers and the claimed "station" to the end-user's computer running a web browser (Compl. ¶¶ 19, 20). Communication over the internet is alleged to be the "means for communicating" (Compl. ¶ 2). The website's display of product information and user interface elements is alleged to be the "means for selectively and interactively presenting... data" (Compl. ¶¶ 18, 19). The complaint alleges that the website's processing of user actions, such as adding items to a cart or placing an order, constitutes processing "according to backward-chaining and forward-chaining sequences" (Compl. ¶ 19). The complaint provides a diagram from the patent, Figure 2, to illustrate the patented architecture, which it alleges is practiced by the accused system (Compl. p. 7).

• Identified Points of Contention:
  • Scope Questions: The case may turn on whether the term "station", as described in the patent with a specific 1980s-era hardware architecture (e.g., DMA unit, independent data paths), can be construed to cover a modern general-purpose computer running a standard web browser. The complaint does not allege that the accused system contains the specific hardware configuration disclosed as the inventive concept in the '508 Patent.
  • Technical Questions: A central question will be what evidence supports the allegation that the accused e-commerce website performs processing "according to backward-chaining and forward-chaining sequences." The complaint raises the question of whether a standard e-commerce workflow (e.g., updating a shopping cart, suggesting related products) meets this limitation, or if the claim requires the specific, dynamic, and quasi-AI reasoning process that was described during patent prosecution to distinguish the invention from a "fixed menu tree" (Compl. ¶ 9, p. 3).

V. Key Claim Terms for Construction

The Term: "station"

• Context and Importance: The definition of "station" is critical because the patent's specification and figures describe a specific hardware terminal, while the complaint accuses a general-purpose computer running third-party browser software. Practitioners may focus on this term to determine if the claim scope is limited to the disclosed hardware embodiment or is broad enough to cover a functionally different, modern computing environment.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: Claim 1 itself describes the station as including a "general purpose computer," language that could support application to modern PCs ( '508 Patent, col. 6:41-42).
  • Evidence for a Narrower Interpretation: The specification's description of the preferred embodiment, particularly Figure 2 and the accompanying text, details a specific hardware architecture with a DMA unit (116) and modem (115) on a data path separate from the video processor (113), which was presented as the novel solution to prior art data congestion (’508 Patent, col. 3:41-48; Compl. p. 7).

The Term: "processing... according to backward-chaining and forward-chaining sequences"

• Context and Importance: This term appears to define the core "intelligence" of the claimed system. Its construction will be central to determining whether the logic of a conventional e-commerce website constitutes infringement.
• Intrinsic Evidence for Interpretation:
  • Evidence for a Broader Interpretation: The patent itself does not provide a formal definition, which may allow for arguments that any dynamic, rule-based response to user input falls within its scope.
  • Evidence for a Narrower Interpretation: The complaint cites prosecution history where the inventor distinguished this processing from a "rigid, pre-ordained sequence... following a fixed menu tree" (Compl. ¶ 9, p. 3). The inventor described it as a "novel capability of processing the answer given by the operator in combination with prior answers and/or other data to formulate or compose a new inquiry," suggesting a process more complex than standard website navigation (Compl. ¶ 9, p. 3).

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement under 35 U.S.C. § 271(b), asserting that Woodland Foods knowingly induces its customers to infringe by encouraging them to use their own devices (i.e., the claimed "station") in combination with the accused website, for example by prompting them to create and sign into accounts (Compl. ¶¶ 26-27).
• Willful Infringement: Willfulness is alleged "on information and belief," based on the assertion that Defendant acted with "full knowledge of the '508 Patent" (Compl. ¶ 24). The complaint does not specify facts supporting pre-suit knowledge.

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

1. A core issue will be one of technological correspondence: can the claims, rooted in a specific 1980s-era hardware architecture designed to solve a data-bus congestion problem, be interpreted to cover a modern, distributed software system (a web server and browser) that does not face the same hardware limitations and is not alleged to contain the novel hardware structure described in the patent?

2. A second dispositive issue will be evidentiary: does the accused e-commerce website's logic perform processing "according to backward-chaining and forward-chaining sequences" as that term was understood in the patent and its prosecution history, or does its functionality amount to the type of "menu-driven approach" the inventor distinguished as prior art? The outcome may depend on whether the plaintiff can demonstrate that the accused system employs a dynamic, inferential reasoning process beyond that of a conventional online store.
