Case Timeline

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

U.S. Patent No. 5,969,698 - "Manually Controllable Cursor and Control Panel in a Virtual Image," Issued October 19, 1999

The Invention Explained

• Problem Addressed: The patent’s background section identifies a problem in the design of portable electronics of the era (e.g., pagers, cellular phones), where the size of physical keyboards and displays was a "limiting factor in determining the size of the receiver" (’698 Patent, col. 1:47-50). Such components required significant physical space and electrical power (’698 Patent, col. 1:19-24).
• The Patented Solution: The invention proposes replacing a "physically large and cumbersome keyboard or control panel" with a software-based equivalent (’698 Patent, col. 6:62-64). It describes a system with a "miniature virtual image display" that presents two key elements to the user: a "virtual control panel image" (such as a virtual keyboard) and a "manually controllable cursor virtual image" (’698 Patent, Abstract). An operator uses externally accessible manual controls, like a touchpad, to move the cursor on the virtual display, select virtual keys on the control panel, and thereby operate the device (’698 Patent, col. 8:35-54).
• Technical Importance: The patented approach sought to enable smaller and more flexible designs for portable devices by moving complex user input functions from dedicated hardware into software viewed on a compact display (’698 Patent, col. 1:56-64).

Key Claims at a Glance

• The complaint asserts infringement of at least independent claim 1 (Compl. ¶13).
• The essential elements of independent claim 1 are:
  • Portable electronics equipment having a virtual display.
  • Electronics for producing a manually controllable virtual cursor image on the display.
  • A virtual control panel image with alpha-numeric keys viewable on the display.
  • Electronics connected so the alpha-numeric keys of the virtual control panel are operable with the virtual cursor image.
  • Electronics further connected to operate the equipment in response to the operation of the virtual keys with the virtual cursor.

III. The Accused Instrumentality

Product Identification

• The Pentax K-5 Digital Camera ("K-5") (Compl. ¶13).

Functionality and Market Context

• The complaint identifies the K-5 as "portable electronic equipment" that includes a "virtual display" in the form of its rear monitor (Compl. ¶¶13-14). A diagram from the product manual identifies the camera's external parts, including the "Monitor." (Compl. p. 3).
• The K-5 is alleged to have electronics that produce a "manually controllable virtual cursor image" and a "virtual control panel image" on its monitor (Compl. ¶14). The complaint provides a screenshot of the K-5's LCD panel, which displays settings such as shutter speed, aperture, and ISO as alphanumeric values. (Compl. p. 5).
• The complaint alleges that users operate the K-5 by interacting with these on-screen virtual controls using the camera's physical dials and buttons (Compl. ¶14, pp. 4-5).
• The complaint does not provide detail regarding the K-5's commercial importance or market position.

IV. Analysis of Infringement Allegations

Claim Chart Summary

Identified Points of Contention

• Scope Questions: A primary issue may be whether the claim term "virtual cursor image", exemplified in the patent as a distinct, movable pointer (’698 Patent, Fig. 8), can be construed to read on the highlighted settings of the K-5's menu system. Similarly, it raises the question of whether a camera's settings display constitutes a "virtual control panel image including alpha-numeric keys" as contemplated by the patent, which illustrates a full QWERTY keyboard (’698 Patent, Fig. 8).
• Technical Questions: The complaint's evidence shows a user turning an "e-dial" to adjust values like shutter speed (Compl. p. 5). A potential point of dispute is whether this mechanism of directly modifying a highlighted value meets the claim limitation that the virtual keys are "operable with the virtual cursor image." The court may need to consider if this requires a distinct "move-and-select" action, as described for the patent's touchpad embodiment (’698 Patent, col. 8:35-40), or if a direct manipulation of a highlighted setting infringes.

V. Key Claim Terms for Construction

The Term: "virtual cursor image"

• Context and Importance: The infringement theory depends on the highlighted, adjustable settings on the K-5's screen being classified as a "virtual cursor image." The definition of this term is therefore critical. Practitioners may focus on this term because the accused functionality (a highlighted menu item) differs visually and operationally from the patent's primary embodiment (a separate, movable pointer).
• Intrinsic Evidence for a Broader Interpretation: The specification describes the cursor as simply an "indicator for the convenience of the operator" and notes it "may utilize anywhere from one to several adjacent pixels, depending upon the shape and size desired" (’698 Patent, col. 8:3-6), which may support a meaning beyond a traditional arrow.
• Intrinsic Evidence for a Narrower Interpretation: The patent consistently describes an operator moving the cursor to a desired location or title (’698 Patent, col. 8:35-44), and Figure 8 depicts a cursor (53) as an entity separate from the control panel (55) it operates upon. This could support an interpretation requiring a distinct, movable object.

The Term: "virtual control panel image including alpha-numeric keys"

• Context and Importance: The complaint alleges that the K-5's settings display, showing values like "1/125" and "F5.6," meets this limitation. The patent's main embodiment is a virtual QWERTY keyboard (’698 Patent, Fig. 8), raising a question of technological scope.
• Intrinsic Evidence for a Broader Interpretation: The specification is not exclusively limited to keyboards, also describing the selection of functions from "pull-down menus" (’698 Patent, col. 6:37-39). This could suggest that any selectable on-screen menu with alphanumeric text qualifies.
• Intrinsic Evidence for a Narrower Interpretation: The patent's text repeatedly uses the term "keyboard" in conjunction with the control panel concept, stating the "function KEYBOARD replaces the need for a physically large and cumbersome keyboard" (’698 Patent, col. 6:61-64). This could be argued to limit the term's scope to virtual text-entry interfaces.

VI. Other Allegations

• Indirect Infringement: The complaint does not allege indirect infringement (i.e., induced or contributory infringement). It asserts only direct infringement under 35 U.S.C. § 271(a) (Compl. ¶13).
• Willful Infringement: The complaint does not contain an explicit allegation of willful infringement. The prayer for relief requests a declaration that the case is "exceptional under 35 U.S.C. § 285" for the purpose of awarding attorneys' fees, but does not specifically request enhanced damages for willfulness (Compl. p. 7).

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

• A core issue will be one of definitional scope: can the terms "virtual cursor image" and "virtual control panel image including alpha-numeric keys", which are rooted in the patent's context of a pointer-and-keyboard interface, be construed to cover the integrated menu highlighting and parameter adjustment functions of a modern digital camera?
• A key evidentiary question will be one of operational mechanism: does the accused camera’s use of physical dials to directly modify highlighted on-screen values constitute an interaction where virtual keys are "operable with" a virtual cursor, as required by Claim 1, or does the claim require a functionally distinct "move cursor, then select" sequence as depicted in the patent's embodiments?
