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

U.S. Patent No. 9,609,487 - "System for providing location relevant information"

The Invention Explained

  • Problem Addressed: The patent’s background section identifies the unsuitability of GPS for indoor use, noting its inability to penetrate building walls and its failure to distinguish between different floors of a multi-story structure (’487 Patent, col. 1:42-52).
  • The Patented Solution: The invention proposes a system of wireless transmitters distributed across multiple floors of a building. A user's mobile device receives signals from nearby transmitters. The system avoids complex triangulation and instead identifies the user's floor by detecting a "common floor identification artifact" shared by transmitters on that floor. It then determines the "closest transmitter" on that floor to provide location-specific information, such as department details or promotions in a retail setting (’487 Patent, Abstract; col. 2:17-29). Figure 1 of the patent illustrates this concept with transmitters (4-13) arranged on different floors (14-16) of a building.
  • Technical Importance: This approach was designed to provide a simplified and reliable method for indoor positioning, enabling context-aware mobile applications in large, complex venues where GPS-based systems are ineffective (’487 Patent, col. 7:1-5).

Key Claims at a Glance

  • The complaint asserts at least independent Claim 1 (’487 Patent, col. 8:5-34; Compl. ¶22).
  • The essential elements of Claim 1 are:
    • A system with a plurality of transmitters located across multiple floors of a building.
    • Each transmitter sends a signal identifying its location.
    • Signals from transmitters on the same floor share at least one "common transmission parameter" and a "common floor identification artifact."
    • Software on a mobile device that:
      • Identifies signals from two or more transmitters.
      • Determines the closest transmitter on the same floor as the mobile device, based in part on the common transmission parameter.
      • Identifies the floor by "selecting the floor associated with the highest number of detected common floor identification artifacts."
      • Displays location-relevant information associated with the determined closest transmitter.
  • The complaint does not explicitly reserve the right to assert dependent claims, though the prayer for relief seeks judgment on "one or more claims" (Compl. ¶36(a)).

III. The Accused Instrumentality

Product Identification

The complaint names HERE Indoor Positioning, HERE Network Positioning, HERE Tracking, and HERE Venues as the Accused Products (Compl. ¶13).

Functionality and Market Context

  • The Accused Products are described as providing "fast and accurate global indoor positioning" to create a "seamless indoor-outdoor-indoor navigation experience" for enterprise and consumer use (Compl. ¶15). The complaint includes a screenshot from Defendant's materials describing how HERE Indoor Positioning provides "smooth positioning from outside to inside, down to the floor of the building you're on" (Compl. ¶23, Fig. 2).
  • The system allegedly utilizes transmitters, such as Bluetooth beacons, deployed in different locations across multiple floors of a venue (Compl. ¶24). An architectural diagram from Defendant's installation guide is provided as an example of beacon deployment on a single floor plan (Compl. p. 9, Fig. 4).
  • A mobile application, the "HERE Indoor Radio Mapper App," is identified as the software component that runs on user devices to collect and process radio data from the transmitters to determine the user's location (Compl. ¶25).

IV. Analysis of Infringement Allegations

’487 Patent Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
a plurality of transmitters located in different locations across multiple floors of the building... Defendant's system comprises a plurality of transmitters (e.g., Bluetooth beacons) located across multiple floors of a building. Figure 4 of the complaint shows an exemplary beacon deployment on a floor plan. ¶24 col. 5:15-21
each transmitter for transmitting a signal for identifying the location of its associated transmitter... Each Bluetooth beacon transmits a signal that identifies its relevant location. ¶24 col. 5:32-35
and wherein signals transmitted by transmitters located on the same floor share at least one common transmission parameter and a common floor identification artifact for identifying the floor on which the respective transmitters are located Signals from beacons on the same floor allegedly share a common transmission parameter (e.g., signal strength) and a common floor identification artifact (e.g., a "floor id" associated with each beacon). ¶24 col. 8:13-18
software for running on the plurality of mobile devices... The system includes software, such as the "Here Indoor Radio Mapper App," which runs on user smartphones. A descriptive screenshot of the app is provided in the complaint as Figure 7. ¶25 col. 5:40-43
identifying signals received substantially concurrently from two or more of the plurality of transmitters The software is alleged to identify signals and signal strength received from two or more Bluetooth beacons. ¶26 col. 6:5-13
determining the closest transmitter on the same floor as the mobile device based at least in part on the at least one common transmission parameter and by identifying the floor on which the mobile device is located by selecting the floor associated with the highest number of detected common floor identification artifacts from the signals received from the two or more of the plurality of transmitters The system allegedly determines the nearest Bluetooth beacon based on signal strength and identifies the floor based on the highest number of signals received from beacons on that floor. ¶27 col. 8:23-31
and displaying on the mobile device location relevant information associated with the location of the determined closest transmitter. The software is alleged to display location-relevant information, such as latitude/longitude coordinates, position on a map, and floor level. Figure 11 of the complaint lists the types of location information displayed. ¶28 col. 6:40-54
  • Identified Points of Contention:
    • Scope Questions: The claim requires a "common floor identification artifact." The complaint alleges this is met by a "floor id associated with each Bluetooth beacon" (Compl. ¶24). This raises the question of whether a unique beacon ID, from which a floor can be determined via a database lookup, satisfies the "common... artifact" limitation, or if the claim requires an identical data flag to be present in the signals of all transmitters on a given floor.
    • Technical Questions: The claim recites a specific method for floor identification: "selecting the floor associated with the highest number of detected common floor identification artifacts." The complaint alleges the accused system detects the floor ID "based on the highest number of signals received from multiple Bluetooth beacons of the same floor" (Compl. ¶27). A potential dispute is whether the accused system's logic of counting signals from beacons known to be on a floor is functionally the same as the claimed method of detecting and counting common artifacts within the signals themselves.

V. Key Claim Terms for Construction

  • The Term: "common floor identification artifact"
    • Context and Importance: This term is the lynchpin of the patented floor-detection method and is central to distinguishing the invention from prior art. Its construction will be critical in determining whether the data structure of the accused HERE system's signals infringes.
    • Intrinsic Evidence for a Broader Interpretation: The specification describes the artifact's function—allowing signals from the same floor to be "easily identified"—but does not define its specific form (’487 Patent, col. 5:35-39). This lack of a precise definition could support a construction that covers any data component within a signal that enables floor-level grouping.
    • Intrinsic Evidence for a Narrower Interpretation: The claim language requires "selecting the floor associated with the highest number of detected common floor identification artifacts" (’487 Patent, col. 8:26-29, emphasis added). This suggests the artifact is a discrete, countable element. An embodiment describes determining the floor by noting that "four signals originate from second floor transmitters, whereas only a single transmission originates from the first floor," which may imply a countable, common marker (’487 Patent, col. 6:25-29).
  • The Term: "closest transmitter"
    • Context and Importance: The system's output is tied to information from the "closest transmitter." How "closeness" is determined—whether by signal strength, timing, or other metrics—is fundamental to the infringement analysis.
    • Intrinsic Evidence for a Broader Interpretation: The specification states that the closest transmitter can be determined "based on one or more of the techniques of analysing received signal strength, received signal noise, and received signal timing" (’487 Patent, col. 6:2-5). This explicit listing of multiple methods may support a broad, functional definition.
    • Intrinsic Evidence for a Narrower Interpretation: The complaint alleges infringement based on determining the closest beacon via "Bluetooth beacon signal strength" (Compl. ¶27). While dependent claims 2 and 3 separately recite signal strength and signal timing, a party could argue that the core inventive concept described in the patent relies on a primary, simplified metric for "closeness" rather than a complex combination of factors (’487 Patent, col. 2:17-24).

VI. Other Allegations

  • Indirect Infringement: The complaint alleges induced infringement, asserting Defendant took active steps by advertising its products for infringing uses and providing documentation and tools (like the HERE Indoor Radio Mapper) that instruct customers on how to set up and use the system in an infringing manner (Compl. ¶¶29-31). Contributory infringement is alleged on the basis that Defendant's system has no substantial non-infringing uses (Compl. ¶¶32-33).
  • Willful Infringement: Willfulness is alleged based on Defendant's post-suit knowledge from the filing of the complaint. The complaint also alleges, on information and belief, that Defendant had pre-suit knowledge through its "due diligence and freedom to operate analyses" (Compl. ¶34).

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

  • A core issue will be one of definitional scope: can the term "common floor identification artifact," which the patent ties to a method of counting detected artifacts, be construed to cover the accused system’s alleged use of a unique "floor id associated with each Bluetooth beacon," which may be resolved through a database lookup rather than by counting common elements in a signal?
  • A key evidentiary question will be one of functional equivalence: does the accused software's alleged process for identifying a floor—"based on the highest number of signals received from multiple Bluetooth beacons of the same floor"—perform the same function, in the same way, with the same result as the claimed step of "selecting the floor associated with the highest number of detected common floor identification artifacts"?
