The specific independent claims asserted in this complaint (Claim 70 of the ’102 Patent and Claim 1 of the ’449 Patent) were reviewed and found patentable in those proceedings.

Case Timeline

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

U.S. Patent No. 5,995,102

• Patent Identification: U.S. Patent No. 5,995,102, “Server system and method for modifying a cursor image,” issued November 30, 1999.
• The Invention Explained:
  • Problem Addressed: The patent describes a problem in the early era of the commercial internet where online advertising, such as banner ads and frames, was often passive and easily ignored by users, while more aggressive methods like self-appearing windows were considered intrusive and annoying (’102 Patent, col. 1:10-30).
  • The Patented Solution: The invention proposes using the on-screen cursor, an element of constant user focus, as a vehicle for delivering content. The system allows a remote server to send instructions to a user's computer to change the cursor's appearance (e.g., shape, color, animation) to correspond with content on the web page, such as an advertisement, thereby creating a more engaging but less disruptive user experience (’102 Patent, col. 3:15-44; Fig. 2).
  • Technical Importance: This approach represented a method to create more dynamic and interactive forms of online branding and user engagement at a time when the industry was seeking to move beyond static advertising formats (’102 Patent, col. 2:26-36).
• Key Claims at a Glance:
  • The complaint asserts independent claim 70 (Compl. ¶16).
  • Essential elements of claim 70 include:
    • A server system for modifying a cursor image to a specific image.
    • The system comprises cursor image data corresponding to the specific image.
    • The system comprises a cursor display code operable to modify the cursor image.
    • The system comprises a first server computer that transmits specified content information to a remote user terminal.
    • The content information includes at least one cursor display instruction indicating a location of the cursor image data.
    • The cursor display code is operable to process the instruction to modify the cursor image in response to movement over a portion of the information displayed on the user's terminal.
  • The complaint does not explicitly reserve the right to assert dependent claims for this patent.

U.S. Patent No. 6,118,449

• Patent Identification: U.S. Patent No. 6,118,449, “Server system and method for modifying a cursor image,” issued September 12, 2000.
• The Invention Explained:
  • Problem Addressed: As a continuation of the '102 Patent, this patent addresses the same technical problem: the ineffectiveness of passive online advertising and the intrusiveness of pop-up style ads (’449 Patent, col. 1:12-35).
  • The Patented Solution: The patented solution is a server-based system that modifies a user's cursor on a remote terminal. A server transmits content to the user, including an instruction that causes the user's browser or a plug-in to retrieve and display a custom cursor image that relates to the on-page content, such as a brand logo or animated icon (’449 Patent, col. 3:18-47; Fig. 3).
  • Technical Importance: The technology provided a means for content providers to leverage the user's own cursor as a branding or entertainment vehicle, aiming to capture user attention without disrupting the browsing experience (’449 Patent, col. 2:28-39).
• Key Claims at a Glance:
  • The complaint asserts independent claim 1 (Compl. ¶38).
  • Essential elements of claim 1 include:
    • A server system for modifying a cursor image to a specific image.
    • The system comprises cursor image data and a cursor display code.
    • A first server computer transmits specified content information to a remote user terminal in response to a request.
    • The content information includes a cursor display instruction and information to be displayed.
    • The cursor display code is operable to process the instruction to modify the cursor image into the specific image.
    • The modification is responsive to displaying at least a portion of the information to be displayed.
  • The complaint also asserts claims 27 and 45, which are similar system claims (Compl. ¶45).

Multi-Patent Capsule

• Patent Identification: U.S. Patent No. 7,111,254, “System for replacing a cursor image in connection with displaying the contents of a web page,” issued September 19, 2006.
• Technology Synopsis: This patent, from the same family as the '102 and '449 patents, describes a system for replacing a standard cursor with new "content information" responsive to the web page being displayed ('254 Patent, Abstract). The system is designed to allow this content information (e.g., a stock price, a weather icon) to be updated, for example, periodically or as new content becomes available ('254 Patent, cl. 4).
• Asserted Claims: The complaint asserts claim 4 (Compl. ¶61).
• Accused Features: The accused feature is the system on Defendant's website that replaces the standard cursor with a "zoom lens" image when a user mouses over a product photograph (Compl. ¶61, ¶63).

III. The Accused Instrumentality

• Product Identification: The server systems, methods, and associated code operating on Defendant’s e-commerce website, "boscovs.com" (Compl. ¶11).
• Functionality and Market Context:
  • The accused functionality is a product image zoom feature. When a user navigates to a product page and moves their cursor over the main product image, the standard cursor is replaced by a "zoom lens" or magnified view of the portion of the image under the cursor (Compl. ¶16-17, ¶22). The complaint provides an annotated visual comparison showing the standard pointer as the "Unmodified cursor image" and the magnified view as the "Modified cursor image" (Compl. p. 11).
  • Plaintiff alleges this functionality is enabled by a combination of HTML and JavaScript code transmitted from Boscov's servers to the user's browser, which then processes the code to create the visual effect (Compl. ¶18-20). The complaint does not contain allegations regarding the specific market positioning of this feature, presenting it as a tool for product inspection on Defendant's commercial website.

IV. Analysis of Infringement Allegations

5,995,102 Infringement Allegations

6,118,449 Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: A potential issue for the court is whether the claims, which arise from a specification heavily focused on solving problems with online advertising (’102 Patent, col. 1:31-36), can be construed to cover a purely functional e-commerce utility like a product zoom feature that lacks an explicit advertising purpose.
  • Technical Questions: The complaint identifies client-side JavaScript as the "cursor display code." A question for the court will be whether this standard web scripting, executed by a browser, meets the claimed limitation of a "cursor display code," particularly as the patent's specification also discusses more specialized components like ActiveX controls and browser plug-ins (’102 Patent, col. 6:8-12; col. 8:39-44).

V. Key Claim Terms for Construction

• The Term: "cursor display code"

• Context and Importance: This term is central to the infringement theory for both the '102 and '449 patents. Its construction will determine whether the accused JavaScript and HTML fall within the claim scope. Practitioners may focus on this term because Defendant could argue that standard webpage scripts interpreted by a browser are distinct from the more specialized "code" (e.g., a plug-in or ActiveX control) contemplated by the patent.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification suggests flexibility, stating that the mechanism can be implemented using "ActiveX®," "Java®," or "VBScript®" that is "embedded in the Cursor Display Instructions 56 within the HTML document" (’102 Patent, col. 10:33-39). This may support Plaintiff’s view that standard web scripting languages are sufficient.
  • Evidence for a Narrower Interpretation: The patent’s detailed embodiment describes a "browser extension or browser plug-in" (34) that interacts with the operating system (28) via an Application Programming Interface (30) (’102 Patent, Fig. 2; col. 8:39-44). This might support an argument that the term requires a component separate from the webpage content itself.

• The Term: "specific image"

• Context and Importance: The infringement allegation is that the "zoom lens" is the "specific image." The definition of this term is critical because the accused zoom feature is a dynamic viewport into another image, not a static, self-contained picture.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The patent is not strictly limited to static images, disclosing "animated, colorful cursors" and an "animated advertising image," which suggests the term could cover dynamic or changing visual content (’102 Patent, col. 4:58; col. 2:66-67).
  • Evidence for a Narrower Interpretation: Many examples in the specification refer to discrete, predefined images, such as a "Fizzy Cola bottle" or a corporate logo (’102 Patent, col. 17:5-11). A party might argue that the accused zoom functionality is a display effect rather than a predefined "image" as contemplated by the inventors.

VI. Other Allegations

• Indirect Infringement: The complaint alleges inducement by asserting that Defendant provides the accused website functionality to end users with the intent that they use it in an infringing manner during the normal course of online shopping. The complaint also alleges the accused functionality lacks substantial non-infringing uses (Compl. ¶31-32, ¶54-55).
• Willful Infringement: The complaint alleges willfulness based on knowledge of the patents acquired "no later than the service of this complaint" (Compl. ¶30, ¶53, ¶64). This allegation, as pleaded, may support a claim for post-filing willfulness but does not establish pre-suit knowledge.

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

• A central issue will be one of claim scope: can the term "cursor display code," rooted in a specification that discusses browser plug-ins and ActiveX controls, be construed to cover the standard HTML and JavaScript code executed by a modern, unmodified web browser?
• A key question for the court will be one of contextual application: will the claims, which the patent specification frames as a solution to problems in online advertising, be interpreted to cover the accused product zoom feature, which serves a primarily functional or utilitarian purpose for e-commerce shoppers?
• An evidentiary question will be one of technical operation: does the accused system's "zoom lens"—a dynamic viewport whose content changes with every cursor movement—qualify as a "specific image" under the patents, which provide examples of discrete logos and icons?
