Case Timeline

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

U.S. Patent No. 9,239,158 - "Battery-Conserving Flashlight And Method Thereof," Issued January 19, 2016

The Invention Explained

• Problem Addressed: The patent addresses the problem of battery-powered devices, such as flashlights, being inadvertently left on, which drains the battery and can render the device unusable when next needed ( ’158 Patent, col. 1:26-34). This leads to waste and the need for frequent battery replacement ( ’158 Patent, col. 1:35-39).
• The Patented Solution: The invention is an electronic device, exemplified by a flashlight, containing a motion sensor and a controller. The controller monitors the device for motion. If the device remains stationary for a predetermined period, the controller automatically "decouples" the battery from the device's main function (e.g., the illumination source) to conserve power ( ’158 Patent, Abstract; col. 4:20-30). The system may also provide a visual or audible alert to the user before shutting down ( ’158 Patent, col. 4:46-56).
• Technical Importance: This approach provides an automated solution to a common user oversight, extending the operational life of portable electronic devices without requiring user intervention. ( ’158 Patent, col. 4:37-45).

Key Claims at a Glance

• The complaint asserts infringement of at least independent claim 15 (Compl. ¶14, 16).
• The essential elements of independent claim 15 are:
  • A body including an opening for accessing an interior of the body;
  • At least one battery disposed in the body and configured for powering the device;
  • A controller disposed in the body configured to determine if the body is in motion, wherein if the body is not in motion for a first predetermined period of time, the controller decouples the at least one battery from the electronic device to conserve energy in the at least one battery; and
  • A visual indicator disposed on an exterior surface of the body, wherein the controller activates the visual indicator.
• The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

Product Identification

• The "Power A Pro Wireless Controller device, and any similar products" (Compl. ¶16).

Functionality and Market Context

• The accused product is a battery-powered wireless video game controller (Compl. ¶16). The complaint alleges the product has "motion sensing capabilities" and a feature where it "may automatically switch to sleep mode when no movement is detected" (Compl. ¶17). A screenshot from the product's user manual states, "The Pro Wireless Controller will enter a 'sleep mode' after 3-5 minutes of inactivity" (Compl. p. 4). The product is powered by three "AAA" batteries accessible via a battery lid on the back (Compl. ¶18, 19). The complaint also alleges the product has "LED status indicator" lights on its exterior surface (Compl. ¶21). The complaint does not provide specific allegations regarding the product's market share or commercial importance.

IV. Analysis of Infringement Allegations

’158 Patent Infringement Allegations

• Identified Points of Contention:
  • Scope Questions: A central question may be whether the accused controller's "sleep mode" constitutes "decoupl[ing] the at least one battery" as required by the claim. The defense may argue that a low-power state is technically distinct from a full decoupling, which the patent's description of a "switch 222" ( ’158 Patent, Fig. 2; col. 4:6-15) could suggest is required.
  • Technical Questions: The complaint identifies the product's "LED CHANNEL INDICATORS" as the claimed "visual indicator" (Compl. p. 6). A key technical question is whether these LEDs, which the user manual states "reference player connection from 1-4 players" (Compl. p. 6), perform the function of the indicator described in the patent. The patent specification suggests the indicator serves as an "alert to the user that the flashlight has been left on" ( ’158 Patent, col. 4:55-56), which raises the question of whether the accused LEDs, which indicate player status, meet the claim limitation in function and purpose.

V. Key Claim Terms for Construction

• The Term: "decouples the at least one battery"

  • Context and Importance: The interpretation of this term is central to infringement. If "decouples" is construed to require a complete electrical break between the battery and the device's circuitry, a software-based "sleep mode" that merely reduces power consumption may not infringe. If it is construed more broadly to mean "ceases providing operational power," the infringement argument may be stronger.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The claim states the purpose of decoupling is "to conserve energy in the at least one battery" ( ’158 Patent, col. 7:28-29). Language in the summary describes the controller action as "shutting off the flashlight" ( ’158 Patent, col. 4:42-43), which could be interpreted functionally rather than requiring a specific hardware action.
    • Evidence for a Narrower Interpretation: The specification explicitly describes the controller operating a physical "switch 222" that is positioned between the "battery 220" and the "illumination source 108" ( ’158 Patent, Fig. 2; col. 4:6-15). This embodiment could be used to argue that "decouples" implies the operation of such a switch to create a physical disconnection.

• The Term: "a visual indicator"

  • Context and Importance: Infringement of this element depends on whether the accused product's existing LEDs, which indicate player status, can be considered the claimed "visual indicator." Practitioners may focus on this term because the patent appears to contemplate an indicator with a specific warning function that may not be present in the accused device.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: Claim 15 itself only requires "a visual indicator disposed on an exterior surface of the body, wherein the controller activates the visual indicator" ( ’158 Patent, col. 7:30-33), without specifying its purpose.
    • Evidence for a Narrower Interpretation: The detailed description states that the "visual indicator 116 serves as an alert to the user that the flashlight has been left on" and is activated "after the controller 224 first determines that the flashlight is not in use" ( ’158 Patent, col. 4:50-56). This could support an interpretation that the indicator must be functionally linked to the power-saving feature as a pre-shutdown warning, not for an unrelated purpose like indicating player connection.

VI. Other Allegations

• Indirect Infringement: The complaint does not allege facts to support claims of induced or contributory infringement.
• Willful Infringement: The complaint alleges that Defendant has knowledge of its infringement "at least as of the service of the present complaint" (Compl. ¶13). This allegation may support a claim for post-filing willful infringement but does not allege pre-suit knowledge.

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

This dispute appears to hinge on two primary questions of claim scope and technical function:

1. A core issue will be one of definitional scope: can the term "decouples the at least one battery," which the patent illustrates with a physical switch, be construed to cover the accused controller’s software-based "sleep mode"?

2. A key evidentiary question will be one of functional purpose: does the accused product's "LED CHANNEL INDICATORS," which show player status, function as the "visual indicator" required by Claim 15, or must the indicator serve as a specific alert that the device is about to power down, as described in the patent’s specification?
