Case Timeline

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

U.S. Patent No. 11,150,779 - “Systems And Methods For Providing An Internet Browser Zoom And Group Bookmark Functions,” issued October 19, 2021

The Invention Explained

• Problem Addressed: The patent describes conventional web searching as a "laborious ping-pong process" between a search engine's list of hyperlinks and the actual target webpages, a process impeded by network latency and the inability to view multiple independent websites at once (’779 Patent, col. 5:48-53). It also notes the lack of integrated tools for managing groups of related webpages (’779 Patent, col. 5:1-6).
• The Patented Solution: The invention proposes an "enhanced web browser" capable of concurrently preloading and displaying multiple webpages, potentially from different website domains, in a single interface (’779 Patent, col. 6:46-54). To manage these pages, it introduces two key functions: a zoom control that can alter the size of one displayed webpage without affecting the others, and a "group bookmark" function that saves the URLs of all currently open pages into a single bookmark folder for later recall (’779 Patent, Abstract; col. 20:30-col. 21:9).
• Technical Importance: By preloading content and providing integrated management tools, the patented method aimed to reduce user-perceived latency and streamline the process of information gathering from multiple online sources (’779 Patent, col. 6:55-63).

Key Claims at a Glance

• The complaint asserts at least independent claim 1 (Compl. ¶26).
• Essential elements of claim 1 (a computerized method) include:
  • loading, by the web browser, a plurality of webpages;
  • displaying a selected webpage from the plurality in an active window;
  • displaying a zoom icon that indicates a current zoom factor and, upon selection, changes the zoom factor for only the selected webpage;
  • displaying a selectable group bookmark icon that, upon selection, generates and saves a group bookmark comprising a data structure storing the URLs for the plurality of webpages.
• The complaint does not explicitly reserve the right to assert other claims.

U.S. Patent No. 8,838,736 - “Internet Browser Zoom Function,” issued September 16, 2014

The Invention Explained

• Problem Addressed: The patent observes that webpages frequently contain fonts and images that are "small and difficult to read" and that conventional web browsers lack a direct and efficient "zoom capability to enlarge a viewing area" (’736 Patent, col. 4:36-42).
• The Patented Solution: The invention discloses a method where a user is presented with an "icon shown on a web browser display" that directly controls the zoom function. When a user selects the icon (e.g., by clicking or rotating a mouse wheel over it), the browser changes the zoom factor of the webpage and simultaneously changes the appearance of the icon itself to reflect the new zoom factor ('736 Patent, Abstract; col. 19:51-col. 20:18).
• Technical Importance: This approach provides a more fluid and intuitive user interface for adjusting webpage magnification compared to navigating through multi-level menus, thereby improving readability.

Key Claims at a Glance

• The complaint asserts at least independent claim 1 (Compl. ¶45).
• Essential elements of claim 1 (a method) include:
  • presenting to a user an icon on a web browser display that directly controls a zoom function, where the icon's appearance indicates the current zoom factor;
  • wherein selection of the icon directly causes the browser to perform two actions:
    1. changing the zoom factor for one or more selected webpages; and
    2. changing the appearance of the zoom icon to indicate the new, current zoom factor.
• The complaint does not explicitly reserve the right to assert other claims.

III. The Accused Instrumentality

Product Identification

The Accused Products are various Lenovo computer products, including the Chromebook Duet 5, Chromebook Duet 3, and IdeaPad series, which come preloaded with the Google Chrome internet browser software (Compl. ¶17). The infringement allegations target the combined hardware and software functionality that allows users to perform group bookmarking and web page zooming (Compl. ¶18).

Functionality and Market Context

The complaint alleges that the Google Chrome browser, as supplied on Lenovo's devices, provides the infringing functionality. The group bookmarking feature is identified as Chrome's "Bookmark all tabs" option, which saves all open tabs into a new bookmark folder (Compl. ¶18, Fig. 2A). Figure 2A in the complaint shows the user interface for group bookmarking all presently open tabs (Compl. ¶18, p. 7). The zoom functionality is identified as the control within Chrome's main menu that allows a user to increase or decrease the magnification of a webpage, which displays the current zoom level as a percentage (Compl. ¶18, Fig. 2D). The complaint alleges that Lenovo derives substantial revenue from selling these products in the U.S. through its own website and major retailers like Best Buy and Walmart (Compl. ¶11, ¶12, ¶19).

IV. Analysis of Infringement Allegations

11,150,779 Infringement Allegations

Identified Points of Contention:

• Scope Questions: A central question may be whether the term "selectable group bookmark icon" can be construed to read on a menu item ("Bookmark all tabs") as alleged in the complaint. The patent’s figures consistently depict a persistent, clickable button in the main browser toolbar (’779 Patent, Fig. 9, 26), which may suggest a narrower scope than a command within a multi-level menu.
• Technical Questions: Does the accused Google Chrome feature of zooming one tab independently meet the claim limitation of changing the factor for a "selected webpage" from "among the plurality of webpages" without altering "another of said plurality", or is there a technical distinction in how the browser handles the "plurality" versus individual, independent tabs?

8,838,736 Infringement Allegations

Identified Points of Contention:

• Scope Questions: A dispute may arise over whether the zoom control located within Chrome's drop-down menu, which is not always visible, constitutes an "icon shown on a web browser display" as contemplated by the patent. The patent specification illustrates the zoom icons as being part of the main, persistent browser interface (’736 Patent, Fig. 21).
• Technical Questions: The claim requires that selection of "said zoom icon" causes both the zoom factor and the icon's appearance to change. In the accused product, the user selects a "+" or "-" button adjacent to a percentage display. The question is whether this entire widget constitutes the claimed "icon" or if there is a functional distinction between the control (the button) and the indicator (the percentage).

V. Key Claim Terms for Construction

• Term: "selectable group bookmark icon" (’779 Patent)

  • Context and Importance: The viability of the infringement allegation against the ’779 Patent largely depends on whether Google Chrome's "Bookmark all tabs" menu option qualifies as a "group bookmark icon". Practitioners may focus on this term because the patent figures show a different UI implementation (a persistent toolbar button) than the accused product (a menu item).
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The term "icon" is not explicitly defined in the patent, and could be argued to encompass any selectable graphical user interface element, including a line of text in a menu, that initiates the claimed function.
    • Evidence for a Narrower Interpretation: The specification consistently illustrates the "group bookmark" control as a distinct, persistent button within the browser's main toolbar (’779 Patent, Fig. 26, element 2603; Fig. 9, element 907). An argument could be made that the invention is limited to such direct-manipulation UI elements, not commands hidden in menus.

• Term: "icon shown on a web browser display" (’736 Patent)

  • Context and Importance: Infringement of the ’736 Patent hinges on whether the zoom control located inside Google Chrome's drop-down menu meets this limitation. The defense may argue that an element inside a menu that is not persistently visible is not "shown on" the display in the manner claimed.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The claim language does not require the icon to be persistently or continuously shown. When the user opens the menu, the icon is "shown on a web browser display" at that time, which may be sufficient to meet the literal claim language.
    • Evidence for a Narrower Interpretation: The patent's abstract states the method "presents to a user an icon," and its figures show the zoom icons as part of the main browser frame, not within a temporary menu (’736 Patent, Fig. 21, element 2103). This may support an interpretation that requires the icon to be more readily accessible than a menu item.

VI. Other Allegations

• Indirect Infringement: For both patents, the complaint alleges induced infringement, stating that Lenovo provides instructions, advertising, and user guides that encourage customers to use the accused Google Chrome features in an infringing manner (Compl. ¶31, ¶50). It also alleges contributory infringement, asserting that the accused functionalities are special features that are not staple articles of commerce and lack substantial non-infringing uses (Compl. ¶32, ¶51).
• Willful Infringement: Willfulness is alleged for both patents, based primarily on knowledge of the patents as of the filing of the complaint (Compl. ¶33, ¶52). The complaint further alleges willful blindness, based on an asserted "policy or practice of not reviewing the patents of others" at Lenovo (Compl. ¶34, ¶53).

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

• A core issue will be one of claim scope: can the term "icon", which the patent specifications illustrate as a persistent button in the main browser interface, be construed to cover the menu-based functionalities ("Bookmark all tabs") and menu-resident controls (the zoom feature) of the accused Google Chrome browser?
• A key evidentiary question will concern the state of the art: given the 2002 priority date, the court will need to determine whether the claimed methods were inventive improvements over the browser technology of that era, or whether they represent a natural and obvious evolution of user interface design, which could raise questions of patent validity.
• A foundational question will be one of direct liability: the case will likely examine whether Lenovo, as a hardware manufacturer that preloads third-party software (Google Chrome), can be held to "use" the patented methods. This may turn on complex legal standards for divided infringement, where the actions of both Lenovo and the end-user are required to practice the claims.
