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

U.S. Patent No. 7,818,691, Zeroclick (issued Oct. 19, 2010)

The Invention Explained

• Problem Addressed: The patent describes the conventional GUI interaction model, which requires two distinct user actions: first, moving a pointer to a control element, and second, performing a separate action like a button press or "click" to activate it (e.g., ’691 Patent, col. 3:1-12). The patent also identifies the problem that simpler movement-only activation systems (without a discrete click) present a high risk of accidental triggering by unintentional pointer movement (’691 Patent, col. 1:44-2:53).
• The Patented Solution: The invention proposes a two-step method to activate a function using only pointer movement. First, a user moves a pointer into contact with a "control area" (1). This action initiates a process, which may make a "predetermined path area" (3) visible. Second, the user performs a specific, subsequent movement of the pointer within this predetermined path area, which "generates a 'click' event" and triggers the control's function. Moving the pointer outside this path before completion resets the control, preventing accidental activation (’691 Patent, Abstract; col. 4:1-12).
• Technical Importance: This approach sought to create a more ergonomic and potentially faster user interface by eliminating the need for a physical click, while providing a safeguard against the accidental function activation that plagued earlier movement-only systems (’691 Patent, col. 3:41-54).

Key Claims at a Glance

• The complaint asserts independent claim 2 (Compl. ¶13).
• Essential Elements of Independent Claim 2:
  • A GUI that may be an update to an existing program.
  • The GUI operates by a "two step method of movement of a pointer" to trigger functions.
  • First step: The pointer is immediately adjacent to or passes within a "control area."
  • Second step: The completion of a subsequent, specified movement of the pointer "generates a 'click' event," which triggers one or more functions (’691 Patent, col. 81:7-24).
• The complaint does not explicitly reserve the right to assert dependent claims.

U.S. Patent No. 8,549,443, Zeroclick (issued Oct. 1, 2013)

The Invention Explained

• Problem Addressed: The ’443 Patent addresses the same technical problem as its parent ’691 Patent: the inefficiency of the traditional point-and-click GUI model and the error-proneness of simplistic movement-only activation systems (’443 Patent, Background of the Invention, col. 3:1-12).
• The Patented Solution: The solution is materially the same as that described in the ’691 Patent, centered on a two-step pointer movement where contact with a "control area" is followed by a subsequent, specific movement within a "predetermined path area" to generate a simulated click (’443 Patent, Abstract; col. 4:1-11). The patent emphasizes that this method can be adapted for error prevention (’443 Patent, col. 82:35-44).
• Technical Importance: This patent continues the development of a GUI interaction paradigm intended to offer a more fluid and ergonomic alternative to the point-and-click standard, particularly for touch and pointer-based devices (’443 Patent, col. 3:13-22).

Key Claims at a Glance

• The complaint asserts independent claim 19 (Compl. ¶21).
• Essential Elements of Independent Claim 19:
  • A GUI as defined in claim 3, wherein...
  • ...the "whole control of a computer is a series of pointer (0) movements."
  • Claim 3, on which claim 19 depends, requires the two-step movement method where the second step within a "predetermined path area" generates a 'click' event, and where this movement is "adjustable for the purpose of error prevention" (’443 Patent, col. 82:20-44, 84:57-59).
• The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

Product Identification

• "certain touch screen cellular telephone and tablet products that utilize Google's Android software," with the LG V30 identified as a representative Accused Product (Compl. ¶¶11, 19).

Functionality and Market Context

• The complaint does not describe the specific functionality of the Accused Products alleged to infringe. It alleges infringement through the "normal and customary use of the Accused Products" by customers (Compl. ¶¶12, 20).
• The complaint’s infringement theories are presented in claim chart exhibits (Exhibits 2 and 4), which were attached to the complaint but are not provided for this analysis (Compl. ¶¶13, 21).

IV. Analysis of Infringement Allegations

The complaint alleges that the Accused Products, such as the LG V30, satisfy all limitations of the asserted claims but provides its substantive infringement analysis in external exhibits not available for review (Compl. ¶¶13, 21). A claim chart summary cannot be constructed.

No probative visual evidence provided in complaint.

Identified Points of Contention

• Scope Questions: A primary question for the ’443 Patent will concern the scope of "whole control of a computer" as required by asserted claim 19. The court may need to determine if specific features in an Android operating system, which also relies on other interactions like taps and hardware buttons, can constitute "whole control" by pointer movement alone.
• Technical Questions: A key technical question for both patents will be whether the accused functionality in the Android OS performs a "two step method of movement" that "generates a 'click' event" as claimed. The analysis will likely focus on whether standard touch-screen gestures (e.g., tap-and-drag, long-press-and-drag) meet the specific claim limitations of an initial contact with a "control area" followed by a separate, "subsequent movement" within a defined "path."

V. Key Claim Terms for Construction

• The Term: "generates a 'click' event"

  • Context and Importance: This term is the functional outcome of the patented two-step method. Its construction is critical because the dispute may center on whether the accused software functionality, which may not generate a literal system-level "click," nonetheless performs an equivalent action that falls within the claim's scope.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The Abstract states the movement "generates a 'click' event which simulates direct clicking of the control" (’691 Patent, Abstract, emphasis added). This language may support an interpretation where any action that achieves the functional result of a click, regardless of its specific software implementation, meets the limitation.
    • Evidence for a Narrower Interpretation: The Background section contrasts the invention with the conventional "button press/click" (’691 Patent, col. 3:5-12). This context could support an argument that the "click event" must be a discrete, programmatic event analogous to a traditional mouse click, rather than merely the completion of a gesture that launches a function.

• The Term: "whole control of a computer" (’443 Patent, cl. 19)

  • Context and Importance: This limitation from a dependent claim asserted from the ’443 Patent sets a potentially high bar for infringement. Practitioners may focus on this term because demonstrating that a smartphone's entire operation is governed by the claimed method could be challenging.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification states that the "method may allow all functions that would have required a pointing device click or key press... to be activated by a pointer movement" and that the "whole control of the computer can be a series of pointer movements" (’443 Patent, col. 3:59-64, emphasis added). This language may suggest the invention provides the capability for whole control, not that every function must be exclusively controlled this way at all times.
    • Evidence for a Narrower Interpretation: The plain meaning of "whole control" suggests comprehensive, not partial, control. An interpretation could be advanced that if a user must still rely on conventional taps, swipes, or hardware buttons for basic operations, the "whole control" limitation is not met.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement for both patents. The factual basis alleged is that Defendants provide "user manuals and online instruction materials on its website" that "encourage and instruct its customers and end users" to use the Accused Products in an infringing manner (Compl. ¶¶12, 20).
• Willful Infringement: The complaint does not contain an explicit count for willful infringement. It alleges that Defendants have had "knowledge of the" asserted patents and the infringing nature of their products "[t]hrough the filing and service of this Complaint" (Compl. ¶¶12, 20). This pleading structure suggests a basis for seeking enhanced damages for post-filing conduct rather than alleging pre-suit willfulness.

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

• A core issue will be one of technical equivalence: Does the accused functionality in the Android operating system, which is built around a vocabulary of taps, swipes, and gestures, perform the specific two-step sequence of (1) contacting a "control area" and (2) completing a "subsequent movement" to "generate a 'click' event," or is there a fundamental mismatch in technical operation?
• A key question of claim scope will be the interpretation of "whole control of a computer" in claim 19 of the ’443 Patent. The case may turn on whether this requires every function of the device to be operable via the patented method, or merely that the method provides a comprehensive control capability, even if other input methods coexist.
• An initial evidentiary question will be the sufficiency of the infringement allegations themselves. Because the complaint's narrative is conclusory and relies entirely on external claim charts for its infringement theory, the adequacy of those charts will be a threshold issue for the litigation.
