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

U.S. Patent No. 10,042,823 - “HYPERLINK WITH GRAPHICAL CUE”

  • Patent Identification: U.S. Patent No. 10,042,823, “HYPERLINK WITH GRAPHICAL CUE,” issued August 7, 2018 (’823 Patent).

The Invention Explained

  • Problem Addressed: The patent addresses the shortcomings of traditional web hyperlinks. Purely textual links often fail to provide a clear indication of their destination, while purely graphical links (like image banners) consume excessive "visual real estate" on a webpage. (’823 Patent, col. 1:46-2:11).
  • The Patented Solution: The invention proposes a multi-step navigation system. A webpage first displays a primary set of hyperlink representations, such as text-based categories. When a user interacts with one of these primary representations (e.g., by hovering or clicking), the system then displays a secondary set of representations (e.g., graphical logos or more detailed text links) that are linked to specific destinations. (’823 Patent, Abstract; col. 16:1-29). This allows for a compact initial presentation while providing richer navigation cues on demand. Figures 5A and 5B illustrate this concept within a financial news website context. (’823 Patent, Figs. 5A-5B).
  • Technical Importance: This approach aimed to improve user interface efficiency by allowing users to quickly preview the contents of a category before committing to a navigation click, a technique facilitated by then-emerging web technologies like AJAX. (’823 Patent, col. 16:35-41).

Key Claims at a Glance

  • The complaint asserts at least independent claim 1.
  • Independent Claim 1 Elements:
    • Causing display of a first set of hyperlink representations "without any first-set-related images."
    • The webpage includes a second set of hyperlink representations that are "pre-downloaded with the webpage" and are "initially hidden."
    • The second set of representations takes the form of "hypertext including one or more textual representations."
    • Allowing receipt of a "first input" (e.g., hover) indicating a selection from the first set.
    • In response, causing a "substantially immediate display" of the second, hidden set.
    • Allowing receipt of a "second input" (e.g., click) indicating a selection from the now-visible second set.
    • In response, navigating to the corresponding destination.
    • Displaying content from the destination "simultaneously with the first set of one or more representations."
  • The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

Product Identification

Functionality and Market Context

  • The complaint focuses on the website’s main navigation menus. These menus present users with a top-level bar of text categories such as "Markets," "Personal Finance," and "News." (Compl. ¶21). When a user hovers a cursor over one of these text categories, a drop-down or fly-out menu appears, presenting a second list of more specific, text-based hyperlinks. (Compl. ¶22). Clicking on a link in this secondary menu navigates the user to a new webpage. (Compl. ¶23). The patent itself includes a figure depicting an older version of the MSN Money interface to illustrate the invention. (’823 Patent, Fig. 5A).
  • The complaint alleges that this navigation system is a central feature of the MSN Money portal, which is a major destination for financial news and data. (Compl. ¶19).

IV. Analysis of Infringement Allegations

’823 Patent Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
cause, after an access to a server, display of a first set of one or more representations of a first set of one or more hyperlinks without any first-set-related images... The MSN Money homepage displays a navigation bar with purely textual categories like "Markets" and "News." ¶21 col. 18:4-9
in connection with a webpage that includes a second set of one or more representations of a second set of one or more hyperlinks that are pre-downloaded with the webpage... The HTML, CSS, and script files loaded with the homepage allegedly contain the data for the drop-down menus that appear on hover. ¶22 col. 18:9-14
wherein the second set of one or more representations are initially hidden... The drop-down menus are not visible upon the initial page load. ¶22 col. 18:14-16
allow receipt of a first input from a user that indicates a selection of one of the first set of representations... The website's code is configured to detect when a user moves their mouse cursor over a top-level navigation category. ¶24 col. 18:21-25
cause, in response to receiving the first input from the user...a substantially immediate display of the second set of one or more representations... Upon detecting the user's hover action, the website's scripting immediately changes the display properties of the corresponding drop-down menu to make it visible. ¶25 col. 18:26-32
allow receipt of a second input from the user indicating a selection of one of the second set of representations... After the drop-down menu appears, the website is able to detect a user’s click on one of the links within that menu. ¶26 col. 18:40-44
cause, in response to receiving the second input...navigation to a destination corresponding to the selected one... A user’s click on a link in the drop-down menu causes the browser to load the webpage specified by that link’s URL. ¶27 col. 18:45-51
display at least a portion of content associated with the destination simultaneously with the first set of one or more representations of the first set of one or more hyperlinks... The complaint alleges that the new page content is displayed in the main body of the browser window while the top-level navigation bar remains visible. ¶28 col. 18:55-63
  • Identified Points of Contention:
    • Technical Question: The allegation that the second set of hyperlinks is "pre-downloaded" may become a key technical dispute. The defense may argue that the content for the drop-down menus is not part of the initial page load but is fetched dynamically via a separate, asynchronous request upon the user's hover action. The case could turn on evidence of the website's specific architecture.
    • Scope Question: Claim 1 requires the second set of representations to be "textual representations." However, the patent is titled "Hyperlink with Graphical Cue" and its specification heavily emphasizes the use of graphical logos for the second set of links (’823 Patent, Figs. 5A-5B; col. 2:20-22). This raises the question of whether the claim language, which appears narrower than the disclosed embodiments, was a deliberate choice during prosecution and how that might impact its interpretation relative to the accused product, which uses textual links in its sub-menus.

V. Key Claim Terms for Construction

  • The Term: "pre-downloaded with the webpage"

    • Context and Importance: This term is central to the infringement analysis, as modern web applications use various methods for loading content. Its construction will determine whether the claim applies only to content embedded in the initial HTML document or if it can also cover content loaded via scripts after the initial page render but before user interaction. Practitioners may focus on this term because it draws a line between older, static web design and modern, dynamic architectures.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: The patent's objective of a "substantially immediate display" could support an interpretation where any technique that loads the data into the browser's memory before the user's hover—even if not in the initial HTML file—satisfies the limitation. (’823 Patent, col. 18:28). The specification also mentions AJAX, a technology for asynchronous data loading, as a potential implementation method. (’823 Patent, col. 16:37).
      • Evidence for a Narrower Interpretation: An opponent could argue the term requires the data for the hidden menus to be transmitted from the server in the same initial package as the main webpage content, distinguishing it from subsequent, on-demand data requests. The description of the feature as enabling display "without requiring additional accesses to the server" may support this narrower view. (’823 Patent, col. 16:38-41).

  • The Term: "without any first-set-related images"

    • Context and Importance: This limitation defines the nature of the first, always-visible set of hyperlinks. If the accused MSN Money navigation bar includes any small icons or graphical elements next to the text categories, the definition of this term could be dispositive of infringement.
    • Intrinsic Evidence for Interpretation:
      • Evidence for a Broader Interpretation: A patentee might argue this term means the hyperlink representation itself is text, not an image, and that the presence of a separate, purely decorative icon adjacent to the text does not make the text "image-related."
      • Evidence for a Narrower Interpretation: The plain language "without any...images" is absolute. A defendant could argue that if any image is visually and functionally associated with the first set of links on the webpage, this limitation is not met, regardless of whether the "" tag itself contains an "" element.

VI. Other Allegations

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

  • A core issue will be one of architectural evidence: Does the accused MSN Money website's menu content meet the "pre-downloaded" limitation as written in the claim, or is it fetched dynamically in a way that falls outside the claim's scope? The outcome will likely depend on forensic analysis of the site's network traffic and source code.
  • A second key question will be one of claim scope and prosecution history: Why does Claim 1 recite a second set of "textual" links when the patent's specification and title emphasize "graphical" cues? The resolution of this tension between the claim language and the specification will be critical in determining the proper construction of the claim and whether it reads on the accused system.
