Case Timeline

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

U.S. Patent No. 7,231,379 - Navigation in a Hierarchical Structured Transaction Processing System

• Patent Identification: 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 describes conventional navigation through hierarchical networks, such as automated telephone menus or early websites, as inefficient and frustrating. A user who makes a wrong selection must often backtrack through multiple steps or start the entire process over (Compl. ¶13; ’379 Patent, col. 2:9-18).
• The Patented Solution: The invention proposes a method to make navigation more efficient by allowing a user to "jump" directly to a desired node (or "vertex") in the hierarchy without traversing the intermediary steps. This is accomplished by receiving a user input containing a keyword and using an index to associate that keyword with a specific, non-adjacent node in the system, thereby bypassing the rigid hierarchical path (Compl. ¶14; ’379 Patent, col. 3:35-43). The patent abstract describes using an "inverted index" to correlate keywords with nodes.
• Technical Importance: This approach aimed to improve the user experience for complex information systems by making data retrieval faster and more intuitive than strict, menu-driven navigation ('379 Patent, col. 2:25-30).

Key Claims at a Glance

• The complaint asserts direct infringement of at least Claim 1 ('379 Patent, col. 22:46-60; Compl. ¶16).
• 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 an input from a user, where the input contains at least one word identifiable with a keyword.
  • Identifying at least one node, other than the first node, that is not directly connected to the first node but is associated with the keyword.
  • Jumping to that identified node.
• The prayer for relief seeks judgment on "one or more claims" of the patent (Compl. ¶V.a).

III. The Accused Instrumentality

Product Identification

• The website located at www.gracobaby.com and its associated subsites, web pages, and functionality (Compl. ¶16).

Functionality and Market Context

• The complaint alleges that the accused website is organized with a hierarchy of "nodes," such as product categories (e.g., "Car Seats," "Strollers") and sub-categories (e.g., "Infant Car Seats & Bases") (Compl. ¶16). The site allegedly includes a search box that accepts keyword input from a user. This functionality is accused of allowing a user to bypass the hierarchical category structure and "jump" directly to a specific product page, which is alleged to be a "node" in the hierarchy (Compl. ¶16). The complaint does not provide detail on market context beyond identifying the products as consumer goods.

IV. Analysis of Infringement Allegations

The complaint includes a reproduction of the patent’s Figure 1 to illustrate a generic hierarchical arrangement of nodes (Compl. p. 4). The infringement theory maps the website's structure and search function onto the elements of Claim 1.

'379 Patent Infringement Allegations

Identified Points of Contention

• Scope Questions: A central question is whether an e-commerce website, with its categories and search functionality, constitutes a "hierarchical arrangement" of "nodes" as contemplated by the patent. The defense may argue that the site is better characterized as a database queried by a search engine, rather than a navigable tree structure in the patent's sense.
• Technical Questions: The analysis may turn on what constitutes "jumping to the at least one node." The case raises the question of whether displaying a list of search results or loading a product page in response to a search query performs the specific function of "jumping" from a "first node" to a non-adjacent "node" within the claimed hierarchy, or if it is a fundamentally different technical operation.

V. Key Claim Terms for Construction

The Term: "hierarchical arrangement"

• Context and Importance: The applicability of the patent to the accused website hinges on this term. Practitioners may focus on this term to dispute whether a modern e-commerce site, which may present information in multiple, non-exclusive ways (e.g., categories, brand pages, search results), fits within the patent's more structured concept of a "tree" or "menu tree."
• Intrinsic Evidence for a Broader Interpretation: The specification provides varied examples, including interactive television program guides and geographic information systems, which may suggest the term is not limited to a single, rigid data structure ('379 Patent, col. 4:1-6).
• Intrinsic Evidence for a Narrower Interpretation: The patent repeatedly uses the term "menu tree" and illustrates the concept with diagrams showing clear parent-child relationships between nodes in distinct levels, which could support a narrower construction requiring a more formally structured hierarchy ('379 Patent, col. 3:9-14, Fig. 1).

The Term: "jumping to the at least one node"

• Context and Importance: This term defines the core infringing act. Its construction will be critical to determining whether the accused website's search-and-display function meets the claim limitation.
• Intrinsic Evidence for a Broader Interpretation: The patent's objective is to allow a user to reach a goal "without necessarily traversing the tree in the rigid hierarchical manner," which could be argued to broadly cover any action that bypasses menu navigation ('379 Patent, col. 5:11-14).
• Intrinsic Evidence for a Narrower Interpretation: The language describes moving from a "first node" to another specific "node" that is "not directly connected." This may be interpreted to require a system where the user has a defined position within the hierarchy that changes, which may differ from a stateless web search that returns a results page.

VI. Other Allegations

The complaint does not contain allegations of indirect or willful infringement.

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

• A threshold issue for the court will be the viability of the case: given that all claims of the '379 Patent were cancelled in an IPR proceeding subsequent to the filing of the complaint, the primary question is whether any valid cause of action remains.
• Assuming the patent were valid, a core issue would be one of definitional scope: can the term "hierarchical arrangement," described in the context of structured "menu trees," be construed to cover the dynamic categorization and search functionalities of a modern e-commerce website?
• A key evidentiary question would be one of functional operation: does the accused website's search feature perform the specific, claimed method of "jumping" between non-connected "nodes" within a hierarchy, or does it operate as a distinct database query mechanism that falls outside the scope of the claims?
