II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 7,231,379 - "Navigation in a Hierarchical Structured Transaction Processing System"
- Issued: June 12, 2007
The Invention Explained
- Problem Addressed: The patent's background describes the inefficiency and potential user frustration in navigating complex, hierarchical systems, such as automated telephone menus or websites, where reaching a specific "goal vertex" requires traversing numerous sequential choices. (’379 Patent, col. 2:9-18).
- The Patented Solution: The invention proposes a method to bypass this rigid, step-by-step navigation. It does so by associating keywords with various nodes (or pages/options) within the hierarchy. When a user provides an input containing a keyword, the system can identify a corresponding node—even one that is not immediately accessible from the user's current position—and "jump" the user directly to it, eliminating intermediate steps. (’379 Patent, col. 3:29-43; Abstract).
- Technical Importance: This approach aimed to make navigation of complex data structures, like those in e-commerce or information retrieval systems, faster and more intuitive for the end-user. (’379 Patent, col. 2:9-12).
Key Claims at a Glance
- The complaint asserts at least independent claim 1. (Compl. ¶13).
- The essential elements of independent claim 1 are:
- A method performed in a system with multiple navigable nodes in a hierarchical arrangement.
- At a first node, receiving a user input that contains at least one word identifiable with a keyword.
- Identifying at least one other node that is not directly connected to the first node but is associated with the keyword.
- Jumping to that identified node.
III. The Accused Instrumentality
Product Identification
The website located at https://store.gibson.com/ and its associated subsites and functionality (the "Accused Instrumentality"). (Compl. ¶13).
Functionality and Market Context
The complaint alleges the Accused Instrumentality is a system with multiple navigable nodes, such as product categories ("Gear," "Hardware," "Lifestyle"), arranged in a hierarchy. (Compl. ¶13). It is alleged to operate by using a search box on its home page (the "first node") to receive user input. This input, containing keywords, is then used to identify specific product nodes. The complaint alleges the website functionality then allows a user to "jump" directly to these product nodes without needing to navigate through the intermediate category nodes. (Compl. ¶¶13-14). No probative visual evidence provided in complaint.
IV. Analysis of Infringement Allegations
’379 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| A method performed in a system having multiple navigable nodes interconnected in a hierarchical arrangement | The website has different product categories (nodes) like "Gear" and "Hardware" that are interconnected in a hierarchical structure. | ¶13 | col. 3:20-30 |
| at a first node, receiving an input from a user of the system, the input containing at least one word identifiable with at least one keyword from among multiple keywords | The website utilizes a search box on the home page node to accept user input, which contains keywords used to identify particular products. | ¶13 | col. 22:49-56 |
| identifying at least one node, other than the first node, that is not directly connected to the first node but is associated with the at least one keyword | The website identifies a particular product node that relates to the keyword input by the user. | ¶13 | col. 22:57-62 |
| and jumping to the at least one node. | The website "allows jumping to those items/nodes without traversing preceding generic category nodes (e.g., Gear, Lifestyle, etc.) in the hierarchy." | ¶14 | col. 22:63-64 |
- Identified Points of Contention:
- Scope Questions: A primary question is whether the term "hierarchical arrangement," as described in the context of IVR systems and early tree structures, can be construed to read on the data architecture of a modern e-commerce website, which may rely on relational databases that are not strictly hierarchical.
- Technical Questions: The infringement theory hinges on the interpretation of "jumping." The analysis will question whether displaying a page of search results constitutes "jumping to the at least one node," or if the claim requires a direct transition to a single, specific destination node without an intervening results page.
V. Key Claim Terms for Construction
The Term: "hierarchical arrangement"
- Context and Importance: The applicability of the patent to the accused website depends on whether the website's structure of categories and product pages qualifies as a "hierarchical arrangement." Practitioners may focus on this term to dispute whether the accused system meets this foundational limitation of the claim.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification suggests broad applicability, listing examples including document retrieval systems and geographic information systems, not just rigid tree structures. (’379 Patent, col. 4:1-5).
- Evidence for a Narrower Interpretation: The patent’s figures consistently depict classic, tree-like diagrams with clear parent-child node relationships, which might support an argument that the term is limited to such explicit structures. (’379 Patent, e.g., FIG. 1, FIG. 6).
The Term: "jumping to the at least one node"
- Context and Importance: This term defines the novel step of the claimed method. Its construction will be critical to determining whether the common e-commerce practice of displaying a search results page infringes.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent describes the invention's purpose as allowing a user to "skip from one vertex to another vertex that may be many rows down the graph," which could be read to encompass any method that bypasses manual navigation through a menu. (’379 Patent, col. 3:30-32).
- Evidence for a Narrower Interpretation: The abstract states the system will "jump to that node without first traversing any other node," which could be interpreted more narrowly to require a direct transition to a single destination, not the presentation of a list of potential nodes (a search results page). (’379 Patent, Abstract).
VI. Other Allegations
- Willful Infringement: The complaint does not contain an explicit allegation of willful infringement. It alleges constructive notice "by operation of law," which does not satisfy the knowledge requirement for a willfulness claim. (Compl. ¶16).
VII. Analyst’s Conclusion: Key Questions for the Case
Claim Validity: The most dispositive issue in this case is the post-filing cancellation of all seven claims of the ’379 patent by the USPTO. While this report analyzes the complaint as it was originally filed, this subsequent invalidation effectively renders the lawsuit moot and is the ultimate barrier to any finding of liability.
Definitional Scope: A core question at the time of filing would have been whether the terminology of the ’379 patent, such as "hierarchical arrangement" and "jumping," could be construed to cover what is now standard search functionality on an e-commerce website.
Obviousness: The fundamental technical question, ultimately addressed in the IPR proceedings, is whether the claimed method was a non-obvious invention or merely the predictable application of a search function to a categorized data set—a common design pattern in web development. The infringement allegations describe functionality that is ubiquitous on the modern web, raising a significant question of whether the patent claimed a patent-eligible invention over the prior art.
