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

U.S. Patent No. 9,261,365 - Device, System and Method for Remotely Entering, Storing and Sharing Addresses for a Positional Information Device (issued Feb. 16, 2016)

The Invention Explained

• Problem Addressed: The patent describes the difficulty and potential danger of manually programming destination addresses into then-current GPS devices, citing issues like inconsistent address formatting across different units and the distraction of data entry while driving (’365 Patent, col. 2:1-25). A further problem identified is the inconvenience of individually programming multiple GPS devices with the same set of addresses (’365 Patent, col. 2:9-15).
• The Patented Solution: The invention discloses a system where a user’s positional device (e.g., a car’s GPS) communicates with a remote server, potentially assisted by a live operator, via a telematics network (’365 Patent, col. 9:7-33). The user provides the desired location information to the server, which then resolves the location into geographic coordinates and transmits those coordinates back to the user's device, automatically programming it for route guidance (’365 Patent, Abstract; col. 9:51-col. 10:7). This system also facilitates sharing location information between different user devices registered with the service (’365 Patent, col. 11:6-44).
• Technical Importance: This approach sought to improve the usability and safety of GPS navigation by centralizing and simplifying the task of address entry, effectively creating a remote-concierge service for programming navigation devices (’365 Patent, col. 2:36-44).

Key Claims at a Glance

• The complaint asserts "one or more claims, including at least Claim 1" (Compl. ¶13).
• Independent Claim 1 recites a method for a "requesting positional information device" to receive location information, with the following essential elements:
  • Sending a request from a requesting positional information device to a server for at least one 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 requires the server to perform intermediate steps: determining a second identifier for the sending device based on the first identifier from the requesting device, and using that second identifier to retrieve the requested address stored in the identified sending device.
• The complaint’s reference to "one or more claims" suggests a reservation of the right to assert additional dependent claims (Compl. ¶13).

III. The Accused Instrumentality

Product Identification

The accused instrumentality is Defendant’s "associated hardware and software for asset locating services (e.g., Inpixon RTLS)," which the complaint collectively terms the "Product" (Compl. ¶13).

Functionality and Market Context

The complaint describes the accused product as 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. ¶13). The complaint does not provide further technical detail on the specific architecture or operation of the Inpixon RTLS, instead incorporating by reference an unattached claim chart exhibit (Compl. ¶18-19).

IV. Analysis of Infringement Allegations

The complaint alleges that infringement can be understood by reference to an attached claim chart in Exhibit B, which was not included with the filed complaint document (Compl. ¶18). The narrative allegations state that Defendant's RTLS products directly infringe by making, using, and testing them, and that the products "practice the technology claimed by the '365 Patent" (Compl. ¶13-14, ¶18). The core of the infringement theory appears to be that the Inpixon RTLS, as a system for managing location information between devices and a central service, performs the steps recited in the asserted claims (Compl. ¶13).

No probative visual evidence provided in complaint.

Identified Points of Contention

• Scope Questions: Claim 1 recites a method of retrieving an "address" that is "stored in at least one sending positional information device" (’365 Patent, col. 14:1-2). A primary question will be whether the "location information" (Compl. ¶13) used in Defendant's asset-tracking RTLS constitutes an "address" as contemplated by the patent, which focuses heavily on street addresses for vehicle navigation.
• Technical Questions: The infringement allegation raises the question of whether the architecture of the Inpixon RTLS matches the specific data flow of Claim 1. The court may need to determine if the accused system involves a "requesting" device pulling information "stored in" a separate "sending" device via a server, or if it operates on a different, more server-centric model where devices primarily report data to a server that acts as the sole information repository. The complaint lacks the detail to resolve this.

V. Key Claim Terms for Construction

The Term: "address"

• Context and Importance: This term is critical because the patent’s background is steeped in the context of human-readable street addresses for vehicle navigation, while the accused product is an RTLS for tracking "assets or objects." The viability of the infringement claim may depend on whether the "location information" in the accused system falls within the construed scope of "address."
• Intrinsic Evidence for a Broader Interpretation: The patent summary describes a method for entering "location information" and determining "coordinates," language that could support a construction where "address" encompasses any data representing a location (’365 Patent, col. 2:53-57).
• Intrinsic Evidence for a Narrower Interpretation: The background section uses "address" exclusively to mean street addresses that are difficult for users to input manually (e.g., "19333 Collins Avenue, Sunny Isles, Fla.") (’365 Patent, col. 2:4-8). Furthermore, Claim 3 distinguishes between an "address" and "longitude and latitude coordinates," which may suggest they are not synonymous and that "address" implies more than just coordinate data (’365 Patent, col. 14:6-9).

The Term: "stored in at least one sending positional information device"

• Context and Importance: Practitioners may focus on this term because it appears to define the architecture of the claimed system. The infringement analysis will turn on whether the accused RTLS actually retrieves information from one device for use by another, as opposed to a system where a server stores all information and devices merely interact with the server's database.
• Intrinsic Evidence for a Broader Interpretation: A party might argue that if a server stores location data that is uniquely associated with a specific sending device's ID, that data is functionally "stored in" the device for the purposes of the claim, as the device is the ultimate source of the data.
• Intrinsic Evidence for a Narrower Interpretation: The plain language of the claim suggests the data physically or logically resides on the sending device itself until it is requested and retrieved (’365 Patent, col. 14:1-2). An embodiment described in the specification involves a server contacting a designated device to "retrieve the stored address information from the internal or external memory of the GPS device," supporting a narrower, device-centric storage interpretation (’365 Patent, col. 11:47-52).

VI. Other Allegations

Indirect Infringement

The complaint alleges both induced and contributory infringement (Compl. ¶13). The basis for inducement is the allegation that Defendant provides "product literature and website materials" that instruct and encourage end users to operate the accused products in an infringing manner (Compl. ¶16).

Willful Infringement

While the complaint does not use the word "willful," it lays the foundation for a claim of post-filing willfulness by asserting that "service of this Complaint, in conjunction with the attached claim chart... constitutes actual knowledge of infringement" and that Defendant has "knowingly, and intentionally continued to induce infringement" at least since being served (Compl. ¶15, ¶17).

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

• A core issue will be one of definitional scope: can the term "address," which is rooted in the patent's context of human-readable destinations for vehicle navigation, be construed to cover the "real-time locations of assets or objects" managed by the accused enterprise RTLS?
• A key evidentiary question will be one of architectural correspondence: does the accused Inpixon RTLS system practice the specific, multi-step data-flow architecture required by Claim 1, particularly the requirement that a server retrieve an address "stored in" one "sending positional information device" based on a request from a different "requesting" device, or is there a fundamental mismatch in technical operation?
