Case Timeline

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

• Patent Identification: U.S. Patent No. 9,261,365, "DEVICE, SYSTEM AND METHOD FOR REMOTELY ENTERING, STORING AND SHARING ADDRESSES FOR A POSITIONAL INFORMATION DEVICE," issued February 16, 2016.
• The Invention Explained:
  • Problem Addressed: The patent's background section identifies several problems with GPS devices circa 2006: the difficulty of programming addresses due to inconsistent formats across devices, the inconvenience of re-entering the same address into multiple vehicles' GPS units, and the safety risks of attempting to program a device while driving (Compl. ¶13; ’365 Patent, col. 1:54-2:25).
  • The Patented Solution: The invention provides a system where a user can communicate a desired location to a remote server, either through a live operator or an automated interface. This server resolves the location into geographic coordinates and transmits them directly to one or more of the user's GPS devices, automatically programming them for navigation without requiring manual entry on the device itself (’365 Patent, Abstract; col. 9:7-10:14). The system is also described as enabling the sharing of addresses stored on one GPS device with another registered device via the central server (’365 Patent, col. 11:5-44).
  • Technical Importance: This approach aimed to make programming GPS devices safer and more efficient, particularly for users who were already driving or needed to synchronize destination information across a fleet of vehicles (’365 Patent, col. 2:38-42).
• Key Claims at a Glance:
  • The complaint asserts at least independent Claim 1 (Compl. ¶28).
  • Claim 1 is a method for receiving location information at a "requesting positional information device" and includes the following essential elements:
    • Sending a request from the requesting device to a server for an address stored in at least one "sending positional information device."
    • The request includes a "first identifier" of the requesting device.
    • Receiving, at the requesting device, a retrieved address from the server.
    • The method further requires that the server performs two key intermediate steps: (1) it "determines a second identifier" for the sending device based on the first identifier received, and (2) it "retrieves the requested at least one address stored in the identified at least one sending positional information device."
  • The complaint does not explicitly reserve the right to assert dependent claims.

III. The Accused Instrumentality

• Product Identification: The accused instrumentality is Defendant's "Family Tracker application" (Compl. ¶23).
• Functionality and Market Context: The complaint alleges the Family Tracker application "utilizes a tracking and management method for monitoring real-time GPS locations to receive real-time locations of assets or objects (i.e., location information) through one or more positional information devices (e.g., desktop or mobile devices)" (Compl. ¶23). The complaint does not provide further technical detail on the application's specific features or architecture beyond this general description. No probative visual evidence provided in complaint.

IV. Analysis of Infringement Allegations

The complaint states that a claim chart comparing Claim 1 of the '365 Patent to the accused instrumentality is attached as Exhibit A (Compl. ¶¶28, 33-34). However, this exhibit was not included with the filed complaint.

In the absence of a claim chart, the infringement theory must be inferred from the complaint's narrative allegations. The plaintiff alleges that the Defendant's Family Tracker application, which is described as a "tracking and management method for monitoring real-time GPS locations," practices the technology claimed in the '365 Patent (Compl. ¶¶23, 33). The core of the infringement allegation appears to be that the application facilitates the remote exchange of location information between devices via a central system, thereby satisfying the elements of at least Claim 1. However, the complaint does not provide specific factual allegations mapping individual components or functions of the Family Tracker application to the discrete limitations of Claim 1, such as how the application performs the steps of using a "first identifier" to determine a "second identifier" and then retrieving an address stored on the "sending positional information device."

V. Key Claim Terms for Construction

• The Term: "positional information device"

• Context and Importance: This term appears in Claim 1 as both the "requesting" and "sending" device. Its construction will be critical to determining if the patent's claims, which were drafted in the context of dedicated GPS hardware, can read on modern smartphones running software applications. Practitioners may focus on this term because the accused instrumentality is a software application, not the dedicated hardware emphasized in the patent's specification.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The claim language itself is broad. The specification states the principles "may be applied to any type of navigation or positional information device including but not limited to a vehicle-mounted device, a GPS receiver coupled to a desktop computer or laptop, etc." (’365 Patent, col. 4:16-20). This could support a reading that includes any device capable of determining its position.
  • Evidence for a Narrower Interpretation: The patent's background and detailed description heavily feature examples of dedicated, vehicle-mounted or handheld "GPS (Global Positioning System) devices" of the type common when the application was filed (’365 Patent, col. 1:26-27; col. 4:13-16). This context could be used to argue for a narrower construction limited to devices whose primary function is navigation.

• The Term: "retrieves the requested at least one address stored in the identified at least one sending positional information device"

• Context and Importance: This limitation requires the server to actively pull a pre-existing, stored address from one user device to send to another. The complaint describes the accused product as a "tracking and management method for monitoring real-time GPS locations" (Compl. ¶23), which may function by pushing real-time location data from a device rather than having a server pull a stored address from it. The case may turn on whether the accused application performs this specific "retrieval" step as claimed.

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: The term "retrieves" is not explicitly defined. A party could argue it encompasses any method by which the server obtains the address from the sending device, including a "push" initiated by the sending device in response to a server prompt.
  • Evidence for a Narrower Interpretation: The specification describes a server that "will contact the device and retrieve the stored address information" (’365 Patent, col. 11:47-49). This language suggests a server-initiated "pull" of previously stored data, which could be argued as a more limited meaning than simply receiving a real-time location update.

VI. Other Allegations

• Indirect Infringement: The complaint alleges that Defendant induces infringement by distributing "product literature and website materials" that instruct end users on how to use the Family Tracker application in a manner that infringes the '365 Patent (Compl. ¶31). The complaint also makes a general allegation of contributory infringement (Compl. ¶28).
• Willful Infringement: The willfulness allegation is based on post-suit conduct. The complaint alleges that the filing of the lawsuit and the service of the accompanying (but missing) claim chart provided Defendant with "actual knowledge" of its infringement, and that any continued infringing activity thereafter is willful (Compl. ¶¶30-32).

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

1. A key evidentiary question will be one of technical operation: Does the accused "Family Tracker" application, described as a tool for "monitoring real-time GPS locations," actually perform the specific method of Claim 1? Specifically, what evidence will show that it retrieves a pre-stored address from one "sending positional information device" for delivery to a "requesting" device, as distinct from simply reporting a device's current location?
2. The case will likely involve a central issue of definitional scope: Can the term "positional information device," which is described in the '365 Patent with reference to dedicated GPS hardware from the mid-2000s, be construed to encompass a modern smartphone that is running a software application as one of its many functions?
3. A further question will be one of claim limitation mapping: In the absence of a detailed claim chart, Plaintiff will need to establish how the server architecture of the accused system performs the specific recited function of using a "first identifier" of a requesting device to determine a "second identifier" of a separate sending device to enable the claimed address retrieval.
