Case Timeline

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

U.S. Patent No. 9,219,982 - "Apparatus and method for automatically refreshing a display of a telephone," Issued December 22, 2015

The Invention Explained

• Problem Addressed: The patent addresses the inconvenience users face when navigating through numerous menu displays on a telephone to find a desired service, especially when their needs change based on time of day or location (e.g., checking traffic in the morning vs. ordering food in the evening) (’982 Patent, col. 1:30-58).
• The Patented Solution: The invention is a telephone system that automatically refreshes its display to show a set of "commonly used communication services" that are relevant to the user's current context or "function" (’982 Patent, col. 2:10-28). This context can be determined by factors like time of day, the telephone's physical location, or a user's activity, thereby presenting relevant options without manual searching (’982 Patent, col. 2:56-65; Fig. 4-5).
• Technical Importance: This approach aimed to make user interfaces more intelligent and efficient by proactively anticipating user needs based on changing environmental or temporal conditions.

Key Claims at a Glance

• The complaint does not specify which claims are asserted, referring only to "exemplary claims" (Compl. ¶11). Independent claims 1 (apparatus) and 13 (method) are the broadest claims in the patent.
• Independent Claim 1 (Apparatus) Elements:
  • A telephone comprising a display panel, a processor, and a datastore.
  • The datastore comprises at least one "function" comprising information relating to a "current location of the telephone" and a user.
  • The telephone is operable to connect to a communication network.
  • The "function" is associated with at least one communication service.
  • The processor is operable to connect to a location server to obtain the "current location," select a "function" from the datastore, and refresh a screen on the display panel to include the communication service associated with the selected function based on the current location.
• The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

Product Identification

• The complaint identifies "at least the Defendant products identified in the charts incorporated into this Count" as the "Exemplary Defendant Products" (Compl. ¶11). Based on the defendant's identity, this is understood to be the Lyft ride-sharing application and associated platform.

Functionality and Market Context

• The complaint does not describe the functionality of the accused products. It alleges that Defendant makes, uses, sells, and imports these products and that they practice the technology claimed by the ’982 Patent (Compl. ¶11, ¶16). The complaint alleges infringement occurs by Defendant's direct use, internal testing, and by its customers' use (Compl. ¶11-12).

IV. Analysis of Infringement Allegations

The complaint does not contain claim charts or detailed infringement allegations within its body. Instead, it states that "Exhibit 2 includes charts comparing the Exemplary '982 Patent Claims to the Exemplary Defendant Products" and incorporates these charts by reference (Compl. ¶16-17). As Exhibit 2 was not provided with the complaint, the specific factual basis for the infringement allegations is not detailed in the available document. The core of the infringement theory appears to be that the accused products "practice the technology claimed by the '982 Patent" and "satisfy all elements of the Exemplary '982 Patent Claims" (Compl. ¶16).

No probative visual evidence provided in complaint.

V. Key Claim Terms for Construction

The complaint does not provide sufficient detail for analysis of specific infringement disputes. However, based on the asserted patent and the nature of the accused product, the following terms from independent claim 1 may become central to the case.

• The Term: "function"

• Context and Importance: This term is the lynchpin of the claim, defining the contextual trigger for refreshing the display. The patent defines "function" broadly as representing "a given set of conditions associated with a user" which can be static (user ID) or variable (time, location, activity) (’982 Patent, col. 4:31-34). Practitioners may focus on whether the operations within the Lyft app, such as a user opening the app at a specific location to hail a ride, meet this definition.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification provides a wide array of examples, including "an office worker on weekday morning, a hotel guest in evenings, or a vehicle driver," and even seasonal events like holidays (’982 Patent, col. 4:35-37, col. 5:15-18). This could support a broad definition covering many user states.
  • Evidence for a Narrower Interpretation: The detailed embodiments often describe a "function" as being pre-associated with a set of "commonly used communication services" in a datastore, such as a morning function linked to weather and traffic services (’982 Patent, col. 4:46-54). A defendant might argue this implies a pre-configured profile, rather than a transient state of using a single-purpose application like Lyft.

• The Term: "communication service"

• Context and Importance: The infringement theory requires mapping features of the accused product to this claim element. The outcome will depend on whether "communication service" is construed broadly to include any network-based service or more narrowly to mean traditional telecommunications.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The specification lists a very broad range of examples, including "commercial services, such as fund transfer services, movie ticketing services or merchandise ordering services," and information services like weather and traffic reports (’982 Patent, col. 1:24-28). This language may support interpreting the Lyft ride-hailing feature as a "communication service."
  • Evidence for a Narrower Interpretation: The patent title and background heavily invoke "telecommunications" and "telephone services" (’982 Patent, Title; col. 1:17-23). An argument could be made that the term's meaning should be anchored in this more traditional context, potentially excluding application-specific services like ride-hailing.

VI. Other Allegations

• Indirect Infringement: The complaint alleges induced infringement, stating that Defendant distributes "product literature and website materials inducing end users and others to use its products in the customary and intended manner that infringes the '982 Patent" (Compl. ¶14).
• Willful Infringement: The complaint does not allege pre-suit knowledge. It asserts that the filing of the complaint itself provides "actual knowledge of infringement" and that any subsequent infringement is therefore willful (Compl. ¶13-14).

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

1. A Definitional Scope Question: A primary issue will be whether the core functionality of the Lyft application can be mapped onto the claim terms of the ’982 Patent. Specifically, can the act of hailing a ride be construed as accessing a "communication service" that is presented based on a user "function" as those terms are defined and described in the patent's specification?

2. An Evidentiary Question of Operation: As the complaint lacks specific allegations, a key question will be what evidence Plaintiff can produce to show that the accused Lyft application performs the specific steps recited in the claims. This includes demonstrating that the application uses a "processor" that "select[s] a function from the datastore" and "refresh[es] a screen" in the particular manner claimed, rather than simply displaying its standard interface upon launch based on location data.

3. A Question of Technical Congruence: The case may turn on the fundamental alignment between the patent's described invention—a customizable, multi-service, context-aware user interface for a "telephone"—and the accused product, which is a specialized, single-purpose application. The court will need to determine if the claims are broad enough to read on modern mobile applications that were not explicitly contemplated in the 2006-era specification.
