II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,609,487 - "System for providing location relevant information", issued March 28, 2017
The Invention Explained
- Problem Addressed: The patent identifies the shortcomings of GPS technology for indoor use, noting that GPS signals cannot penetrate buildings, cannot distinguish between elevations (i.e., different floors), and are often inaccurate for slow-moving pedestrians (’487 Patent, col. 1:35-53).
- The Patented Solution: The invention proposes a system that uses a plurality of wireless transmitters (e.g., Wi-Fi or Bluetooth beacons) placed at various locations across multiple floors of a building. A user's mobile device receives signals from these transmitters. The software on the device determines which transmitter is closest and, crucially, identifies which floor the user is on. This is achieved by having transmitters on the same floor share a "common floor identification artifact" in their signals. The system determines the user's floor by selecting the floor associated with the highest number of these detected artifacts, and then provides location-relevant information, such as a map or store promotions ('487 Patent, Abstract; col. 6:20-44).
- Technical Importance: This approach provides a method for reliable, contextually relevant indoor navigation that does not depend on GPS, complex triangulation, or a direct line of sight to satellites, making it functional inside multi-story structures ('487 Patent, col. 2:38-55).
Key Claims at a Glance
- The complaint asserts at least independent claim 1 (Compl. ¶19).
- The essential elements of independent claim 1 are:
- A system for providing location relevant information to users of mobile devices within a multi-story building.
- A plurality of transmitters located across multiple floors, where signals from transmitters on the same floor share at least one common transmission parameter and a common floor identification artifact.
- Software on the mobile devices for:
- identifying signals received from two or more transmitters;
- determining the closest transmitter on the same floor as the mobile device based on the common transmission parameter and by identifying the floor by selecting the one associated with the highest number of detected common floor identification artifacts; and
- displaying location-relevant information associated with the determined closest transmitter.
- The complaint does not explicitly reserve the right to assert dependent claims, but states infringement of "one or more claims" (Compl. ¶19).
III. The Accused Instrumentality
Product Identification
The accused product is Defendant's "IndoorAtlas sensor fusion stack positioning technology," which is integrated into mobile applications via an SDK (Compl. ¶10, ¶22; Figure 4).
Functionality and Market Context
The accused technology is described as a "hybrid indoor positioning platform" that enables location services within buildings (Compl. ¶20; Figure 2). It allegedly functions by "fusing all available information sources," which include not only Bluetooth beacons and Wi-Fi signals, but also geomagnetic fingerprint maps, data from gyroscopes and accelerometers (IMU sensors), and barometric height information (Compl. ¶20; Figure 2). The platform is marketed to application developers to "build seamless location based experiences" for end-users in venues like shopping malls and offices (Compl. ¶12, ¶27). The complaint includes a screenshot from Defendant's website showing a map with a route on the "Second Floor," illustrating the multi-story capability of the accused system (Compl. Figure 5).
IV. Analysis of Infringement Allegations
'487 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| A system for providing location relevant information to users of a plurality of mobile devices within a multi-storey building, the system comprising: | Defendant is alleged to practice a system (IndoorAtlas Indoor Positioning system) for providing location-based navigation information to mobile phone users within multi-story buildings like malls and offices (Compl. ¶20). | ¶20 | col. 1:16-22 |
| a plurality of transmitters located in different locations across multiple floors of the building, each transmitter for transmitting a signal for identifying the location of its associated transmitter, 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; | The system allegedly comprises a plurality of transmitters (beacons) located across multiple floors. The complaint alleges that beacons on the same floor share a common transmission parameter (e.g., signal strength) and a common floor identification artifact (e.g., the floor level associated with each beacon) (Compl. ¶21). The complaint provides an "Example Beacon Installation" diagram to illustrate this placement (Compl. Figure 7). | ¶21 | col. 5:16-38 |
| software for running on the plurality of mobile devices, the software being operable on each mobile device for: identifying signals received substantially concurrently from two or more of the plurality of transmitters; | The complaint alleges Defendant provides software (an SDK and app) that runs on smartphones and is enabled for identifying signals from multiple transmitters (beacons). A screenshot showing beacon environment quality is provided as evidence of the software identifying signals from multiple beacons (Compl. ¶22, ¶23; Figure 12). | ¶22, ¶23 | col. 6:50-53 |

Identified Points of Contention
- Scope Questions: A central question may be whether the accused system's method for floor identification meets the specific requirements of the claim. The claim recites identifying the floor by "selecting the floor associated with the highest number of detected common floor identification artifacts." The complaint alleges this is met by detecting the "highest number of signals received from multiple beacons of the same floor" (Compl. ¶24). The court will need to determine if merely receiving a signal from a beacon on a given floor is equivalent to detecting a "common floor identification artifact," or if the claim requires a specific data flag or identifier to be transmitted and counted.
- Technical Questions: The complaint states that the accused system uses a "hybrid" approach, fusing data from geomagnetic maps, barometric sensors, and other sources for positioning and "automatic floor selection" (Compl. ¶20; Figure 2). This raises the question of whether the accused system actually performs the specific two-part logic of Claim 1—(1) finding the closest transmitter on a floor and (2) identifying that floor by counting artifacts—or if it primarily relies on other data sources (like barometric pressure) for floor detection, which may not be covered by the claim's language.
V. Key Claim Terms for Construction
The Term: "common floor identification artifact"
- Context and Importance: This term is the lynchpin of the patent's method for distinguishing between floors. Its definition is critical because if the accused system does not use something that qualifies as an "artifact," or if its method of floor identification does not rely on counting these "artifacts," the infringement allegation may falter. Practitioners may focus on this term because the complaint's theory appears to equate receiving a signal from a known-floor beacon with detecting an "artifact" (Compl. ¶24), a position the defendant may challenge as overly broad.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent does not provide a formal definition. A party could argue that because the transmitters are known to be on a specific floor, any unique part of their signal (e.g., a MAC address linked to a floor in a database) could implicitly function as an "artifact."
- Evidence for a Narrower Interpretation: Claim 1 distinguishes between a "signal for identifying the location of its associated transmitter" and the "common floor identification artifact." The specification states that location signals from transmitters on the same floor "share a common floor identification artifact," suggesting it is a discrete, shared piece of data within the signals, rather than the signal itself ('487 Patent, col. 6:25-28). The patent further describes this as a "feature [that] allows signals originating from the same floor to be easily identified" ('487 Patent, col. 6:36-38).
The Term: "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"
- Context and Importance: This clause specifies the method for floor determination. The dispute may turn on whether the accused system uses this specific counting-based logic. The complaint acknowledges the accused system performs "automatic floor selection" using multiple data sources (Compl. ¶20; Figure 2). The construction of this "by selecting" clause will determine if other methods of floor identification, such as using barometric pressure or geomagnetic data, fall outside the claim scope.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: A plaintiff might argue that "selecting" is a general term and that any algorithm which gives more weight to signals from one floor over another is effectively "selecting" based on a "higher number" of inputs from that floor.
- Evidence for a Narrower Interpretation: The claim language recites a specific logical step: counting "artifacts" and selecting the floor with the highest count. The specification supports this specific mechanism: "the software can determine that four signals originate from second floor transmitters, whereas only a single transmission originates from the first floor, and therefore the user is on the second floor" ('487 Patent, col. 6:25-30). This suggests a direct counting method, not a probabilistic fusion of different data types.
VI. Other Allegations
Indirect Infringement
The complaint alleges inducement based on Defendant’s advertising, which encourages developers to "[b]uild seamless location based experiences" and provides an SDK and documentation to enable infringing use by customers and end-users (Compl. ¶27). Contributory infringement is alleged on the basis that the accused functionality has no substantial non-infringing uses (Compl. ¶30).
Willful Infringement
Willfulness is alleged based on Defendant’s purported knowledge of the patent from its "due diligence and freedom to operate analyses," and at a minimum, from the filing and service of the complaint itself (Compl. ¶31).
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" be construed to mean the mere reception of a signal from a beacon known to be on a specific floor, as the complaint's allegations suggest, or does it require a discrete data element shared by transmitters on the same floor, as the patent specification appears to describe?
- A key evidentiary question will be one of functional equivalence: does the accused system's "automatic floor selection," which admittedly fuses data from geomagnetic, barometric, and other sensors, perform the specific counting-based logic required by Claim 1 ("selecting the floor associated with the highest number of detected... artifacts"), or does it employ a fundamentally different technical method for determining the user's floor?
