Case Timeline

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

U.S. Patent No. 7,218,056 - Lighting device with multiple power sources and multiple modes of operation, Issued May 15, 2007

The Invention Explained

• Problem Addressed: The patent addresses the problem that conventional lighting devices become inoperable when their main power source is lost, which can be "problematic in many situations where continued lighting may be desired" (’056 Patent, col. 2:17-23).
• The Patented Solution: The invention is a self-contained lighting device, such as an LED bulb, that includes both a connection to a primary power source and an internal rechargeable battery. A controller manages two distinct modes: a "normal operation" mode that powers a set of light sources from the main power line, and a "backup operation" mode that automatically activates upon power loss, drawing from the battery to power a "limited number" of light sources to conserve energy (’056 Patent, col. 9:58-65; col. 4:26-31). This allows the device to function as a standard light bulb that can also provide emergency lighting.
• Technical Importance: The technology provides a retrofittable solution for emergency lighting that can be installed in standard light sockets without requiring specialized wiring for a separate emergency power system (’056 Patent, col. 4:56-62).

Key Claims at a Glance

• The complaint does not specify which claims are asserted, referring only to the "Exemplary ’056 Patent Claims" (Compl. ¶12). Independent claim 1 is representative.
• Independent Claim 1 requires:
  • At least two light sources mounted on a single printed circuit board (PCB).
  • A battery configured to store power.
  • A controller to receive power from a power source and the battery and control power distribution.
  • The controller is configured to distribute power from the main source to "the at least two light sources" during "normal operation."
  • The controller is also configured to distribute power from the battery to a "limited number of the at least two light sources" during "backup operation," where this limited number is "less than the number" of sources powered during normal operation.
• The complaint does not explicitly reserve the right to assert dependent claims.

U.S. Patent No. 7,391,159 - Lighting device with multiple power sources and multiple modes of operation, Issued June 24, 2008

The Invention Explained

• Problem Addressed: As a continuation of the '056 Patent's application, the '159 Patent addresses the same problem of lighting failure during a power outage (’159 Patent, col. 2:25-30).
• The Patented Solution: The solution is a lighting device with a controller that manages power from a main source and a secondary battery. The controller operates in a "first mode" for "non-emergency illumination" and a "second mode" for "emergency illumination," with the latter being powered by the battery (’159 Patent, col. 9:62-65). The specification describes the second mode as potentially being triggered by an emergency alert message or a loss of power, and it can involve different lighting characteristics such as flashing or displaying a different color to serve as a warning (’159 Patent, col. 8:9-10; col. 6:45-49).
• Technical Importance: This invention builds on the concept of a dual-power bulb by framing the operational states in terms of "emergency" and "non-emergency" functions, allowing for more complex, programmable responses to different triggers.

Key Claims at a Glance

• The complaint does not specify which claims are asserted, referring only to the "Exemplary ’159 Patent Claims" (Compl. ¶21). Independent claim 1 is representative.
• Independent Claim 1 requires:
  • A number of light sources on a common PCB.
  • A controller for distributing power from a main source and a secondary battery to "a selective one or more of the light sources."
  • Power distribution occurs according to a "first mode" associated with "non-emergency illumination" and a "second mode" associated with "emergency illumination."
  • A battery for powering the light sources in the second mode.
  • A common housing for the components.
• The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

Product Identification

The complaint does not identify any specific accused products by name (Compl. ¶12, 21). It refers generally to "Exemplary Defendant Products" whose identities are allegedly detailed in claim charts provided as Exhibits 3 and 4. However, these exhibits were not filed with the complaint and are not available on the public docket.

Functionality and Market Context

The complaint does not provide sufficient detail for analysis of the accused products' specific functionality or market context, as this information is contained within the non-provided exhibits (Compl. ¶17, 26). The complaint summarily alleges that the products practice the technology claimed in the patents-in-suit. No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint alleges direct infringement of both patents but relies entirely on incorporating by reference claim charts in Exhibits 3 and 4, which were not filed with the complaint. Therefore, a detailed element-by-element analysis based on the complaint's allegations is not possible.

'056 Patent Infringement Allegations

The complaint summarily alleges that Defendant's "Exemplary Defendant Products" practice the technology of the '056 Patent and that they "satisfy all elements of the Exemplary '056 Patent Claims" (Compl. ¶17). The specific factual allegations mapping product features to claim elements are contained in the non-provided Exhibit 3 (Compl. ¶18).

'159 Patent Infringement Allegations

Similarly, for the '159 Patent, the complaint alleges that the accused products practice the claimed technology and "satisfy all elements of the Exemplary '159 Patent Claims" (Compl. ¶26). The specific factual support for this allegation is contained in the non-provided Exhibit 4 (Compl. ¶27).

Identified Points of Contention

• Factual Questions: The central factual question for both patents will be whether discovery reveals that the accused products actually operate as claimed. Specifically for the '056 Patent, a key issue will be whether the products, upon loss of main power, power a "limited number" of light sources that is verifiably "less than the number" powered during normal operation, as required by claim 1.
• Scope Questions: For the '159 Patent, a dispute may arise over whether the accused products’ backup functionality constitutes "emergency illumination" as required by the claims. The court may need to determine if this term requires a specific warning or egress-related function, as described in the specification, or if any illumination during a power outage qualifies.

V. Key Claim Terms for Construction

"a limited number of the at least two light sources ... being less than the number of the at least two light sources powered during normal operation" ('056 Patent, Claim 1)

• Context and Importance: This quantitative limitation is a core feature of the claimed invention, distinguishing the power-saving "backup operation" from "normal operation." Infringement hinges on demonstrating that the accused device reduces the quantity of active light emitters, not merely their collective brightness.
• Evidence for a Broader Interpretation: A plaintiff may argue the plain language requires only a reduction of at least one light source (e.g., from N to N-1) to meet the "less than" requirement.
• Evidence for a Narrower Interpretation: A defendant may argue that the term "limited number," in the context of providing emergency lighting, implies a significant reduction intended to "maximize battery life and illumination time" (’056 Patent, col. 8:1-3).

"second mode of operation being associated with emergency illumination" ('159 Patent, Claim 1)

• Context and Importance: This term defines the purpose and character of the battery-powered mode. Its construction will determine what types of backup lighting functionality fall within the claim's scope. Practitioners may focus on this term because many modern LED bulbs have a backup feature, and the case may turn on whether that feature is for "emergency illumination."
• Evidence for a Broader Interpretation: A plaintiff may argue that any illumination provided when main power is unavailable is inherently for an "emergency" and thus constitutes "emergency illumination."
• Evidence for a Narrower Interpretation: A defendant could point to the specification, which describes "emergency illumination" in the context of responding to "emergency alert messages" or creating "a direction egress pattern" (’159 Patent, col. 7:50-52; col. 4:50-51). This could support an interpretation requiring more than just staying on; it may require a specific warning or guidance characteristic.

VI. Other Allegations

Indirect Infringement

The complaint alleges induced infringement for both patents. The factual basis is Defendant's sale of the accused products along with "product literature and website materials" that allegedly instruct and encourage end-users to operate the products in an infringing manner (Compl. ¶15-16, 24-25).

Willful Infringement

The complaint does not use the word "willful" but alleges that service of the complaint constitutes "Actual Knowledge of Infringement" (Compl. ¶14, 23). This allegation establishes a basis for seeking enhanced damages for any infringement that continues post-filing.

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

The resolution of this dispute, based on the initial complaint, will likely depend on the answers to two fundamental questions:

1. An evidentiary question of operation: As the complaint lacks specific factual allegations and relies on non-public exhibits, a threshold issue will be whether discovery confirms that the accused products actually perform the functions required by the claims. Does an accused product, upon power loss, reduce the number of active light sources (for the '056 patent), or does it operate in distinct, programmable modes for "non-emergency" versus "emergency" illumination (for the '159 patent)?

2. A legal question of claim scope: The case will likely involve a dispute over the definition of the claimed backup function. Can the term "emergency illumination" in the '159 patent be construed to cover any generic, reduced-power state during a power outage, or does the patent's specification limit the term to lighting that provides a specific warning or egress-guidance function?
