II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 8,750,784 - "Method, system and server for authorizing computing devices for receipt of venue-based data based on the geographic location of a user," Issued June 10, 2014
The Invention Explained
- Problem Addressed: The patent’s background section describes the limitations of the spectator experience at live venues, where attendees have a passive viewing role, subject to the single perspective offered by large screens and unable to select their own camera angles or replays (’784 Patent, col. 2:16-48).
- The Patented Solution: The invention proposes a system to solve this problem by authorizing a user's handheld device (e.g., a PDA or smartphone) to receive venue-specific data based on the device's determined geographic location within the venue. A "venue positioning system" (VPS) deployed in the venue determines the device's location, and a server then uses this location information to grant access to services like alternative video feeds, statistics, or other interactive content, thereby giving the user control over their viewing experience (’784 Patent, Abstract; col. 4:28-44).
- Technical Importance: The described technology represents a shift from a one-to-many broadcast model for in-venue entertainment to a personalized, interactive model controlled by the individual attendee (’784 Patent, col. 2:49-58).
Key Claims at a Glance
- The complaint asserts infringement of claims 1-20 (Compl. ¶8). Independent claims 1 (method), 9 (system), and 17 (server) are the basis for the allegations.
- Independent Claim 1 (Method) requires:
- Determining a user's location within a venue via a wireless signal from at least one "VPS device" deployed in the venue.
- The VPS device must use a "triangulation method" to determine the location of the user's wireless handheld device.
- Allowing the user's device to receive a service from a server over a wireless network, where the allowance is "based on said location information."
- The complaint does not specify which, if any, dependent claims it will prioritize.
III. The Accused Instrumentality
Product Identification
The complaint accuses "systems, products, and services that facilitate authorizing access by at least one user of at least one service associated with a venue and provided via a wireless network based on a determined location of at least one computing device" (Compl. ¶8). The complaint does not identify any specific Cisco product or service by name.
Functionality and Market Context
- The accused instrumentalities are alleged to be maintained, operated, and administered by Cisco to provide location-based authorization for services at venues (Compl. ¶8).
- The complaint does not provide sufficient detail for analysis of the specific technical functionality of the accused products or their market positioning beyond the general allegation that Cisco sells and offers them for sale (Compl. ¶2).
IV. Analysis of Infringement Allegations
The complaint states that support for its infringement allegations "may be found in the the chart attached as exhibit B," but this exhibit was not included with the filed complaint. The following analysis is based on the narrative allegations.
'784 Patent Infringement Allegations
| Claim Element (from Independent Claim 1) | Alleged Infringing Functionality | Complaint Citation | Patent Citation |
|---|---|---|---|
| determining, via a wireless signal obtained from at least one VPS device associated with a venue positioning system deployed within a venue, a location of at least one user... | Defendant's accused systems allegedly determine the location of a user's wireless handheld device within a venue. | ¶8 | col. 22:38-58 |
| wherein the at least one VPS device uses a triangulation method to determine the location of the wireless hand held device within the venue... | The complaint alleges infringement of this limitation but does not provide specific facts explaining how the accused systems employ a "triangulation method." | ¶8 | col. 23:16-17 |
| allowing said at least one computing device to receive said at least one service from a server over a wireless network based on said location information... | Defendant's systems allegedly authorize and allow a user's device to receive a service based on its determined location within the venue. | ¶8 | col. 4:28-44 |
No probative visual evidence provided in complaint.
Identified Points of Contention
- Scope Questions: A central question will be whether standard wireless networking components, such as Wi-Fi access points that can be used for locationing, fall within the scope of a "venue positioning system (VPS) device" as that term is used in the patent. The defense may argue the term is limited to the dedicated positioning hardware depicted in the patent’s figures (’784 Patent, Fig. 18), while the plaintiff may argue for a broader interpretation.
- Technical Questions: The claim explicitly requires the use of a "triangulation method." A key technical dispute will likely be whether the accused Cisco systems, which are not identified, actually use triangulation for location determination, or if they use other modern techniques such as Wi-Fi signal strength fingerprinting, time-of-flight, or angle of arrival, and whether those alternative methods fall within the claim's scope.
V. Key Claim Terms for Construction
The Term: "venue positioning system (VPS) device"
- Context and Importance: This term is foundational to the infringement case. Whether Cisco's hardware (e.g., its wireless access points) can be characterized as a "VPS device" will be a critical point of dispute. Practitioners may focus on this term because the patent's description of a VPS appears distinct from a standard data-communication access point.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent does not provide a formal definition, which may support an argument for a broader, plain-meaning interpretation. The specification refers generally to "transponders" that can help determine a device's location (col. 23:9-12), which a party could argue covers any device that responds to a signal for positioning purposes.
- Evidence for a Narrower Interpretation: The specification describes and depicts VPS devices as specific hardware components placed at strategic locations within a venue, such as the top and bottom of staircases in a stadium section, for the purpose of positioning (col. 22:49-58; Fig. 18). This may support a narrower construction limited to hardware deployed in such a dedicated positioning configuration.
The Term: "triangulation method"
- Context and Importance: This specific method of location determination is an express limitation in the independent claims. The infringement case depends on proving that the accused systems employ this particular technique.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent does not define the term. A party could argue it encompasses any location-determination method based on the geometric properties of triangles, potentially including techniques like trilateration (which uses distances from multiple points).
- Evidence for a Narrower Interpretation: A party could argue for a more technically precise definition distinguishing triangulation (based on measuring angles) from trilateration (based on measuring distances) and other Wi-Fi positioning methods. The patent's use of the term without further elaboration (col. 23:16-17) suggests the parties may need to rely on extrinsic evidence, such as expert testimony, to establish its meaning to a person of ordinary skill in the art at the time of the invention.
VI. Other Allegations
- Indirect Infringement: The complaint alleges inducement by asserting that Defendant "actively encouraged or instructed others (e.g., its customers)" on how to use its products and services in an infringing manner (Compl. ¶10). It also alleges contributory infringement by claiming there are "no substantial noninfringing uses" for the accused products and services (Compl. ¶11).
- Willful Infringement: Willfulness allegations are based on Defendant’s alleged knowledge of the '784 patent "from at least the filing date of the lawsuit" (Compl. ¶10-11). This frames the willfulness claim as being based on post-suit conduct.
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of definitional scope: can the term "venue positioning system (VPS) device," which the patent illustrates as dedicated hardware placed for locationing, be construed to cover multi-purpose enterprise wireless access points that are also capable of location determination?
- A key technical and evidentiary question will be one of methodological proof: what evidence can Plaintiff produce to demonstrate that the accused, yet-unidentified, Cisco systems employ the specific "triangulation method" required by the claims, as distinguished from other prevalent wireless locationing technologies?
- A foundational question for the litigation will be one of specificity: will the complaint's general allegations against unspecified "systems, products, and services," without identifying any accused Cisco product line, withstand a potential challenge under federal pleading standards?
