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

U.S. Patent No. 7,996,861 - "Flexible Interface for Secure Input of Pin Code," issued August 9, 2011

The Invention Explained

  • Problem Addressed: The patent addresses the security risk of authenticating a user's right to access protected content, such as a pay-per-view program, where the application providing the content requests a Personal Identification Number (PIN) (Compl. ¶28). The technical problem is preventing the application itself from accessing and potentially compromising the user's secret PIN (Compl. ¶28).
  • The Patented Solution: The invention proposes separating the PIN entry and verification process from the content application. An application can request user authentication, but the PIN is supplied directly to a "security manager" component rather than the application. This security manager verifies the PIN and then informs the application whether access is authorized, without ever disclosing the PIN to the application (Compl. ¶28; ’861 Patent, Abstract).
  • Technical Importance: This approach enhances security in conditional access systems by isolating sensitive authentication credentials from potentially less secure third-party applications, a key principle in secure system design (Compl. ¶28).

Key Claims at a Glance

  • The complaint asserts independent Claim 9 (Compl. ¶29).
  • Essential elements of Claim 9 (a method) include:
    • Receiving a request from a user to run an application.
    • The application presenting a PIN entry field.
    • A security manager receiving a request for user authentication from the application.
    • The security manager supplying information to the application about PIN code entering key-pressing operations, but not supplying the entered PIN code itself.
    • The application presenting crypted information in the PIN entry field corresponding to the key-pressing operations.
    • Giving authorization to run the application if the entered PIN code matches a registered PIN code.

U.S. Patent No. 7,421,729 - "Generation and Insertion of Indicators Using An Address Signal Applied To A Database," issued September 2, 2008

The Invention Explained

  • Problem Addressed: The patent addresses the technical problem of how to associate interactive content or data with specific segments within a video program stream, as opposed to prior art methods that only allowed for data related to the entire program (Compl. ¶49).
  • The Patented Solution: The invention uses a time code generator synchronized with a video stream to identify a precise location. An "address generator" uses this time code to generate an address, which acts as an index into a database. The database provides an "indicator" (e.g., a tag for a play highlight) stored at that address, and an encoder then inserts this indicator into the video stream (Compl. ¶49; ’729 Patent, Abstract).
  • Technical Importance: This technology enables time-synchronized interactive features, such as "Big Play Markers" or contextual overlays, to be embedded directly into a video stream, forming a foundation for modern interactive sports broadcasting (Compl. ¶¶ 48-49).

Key Claims at a Glance

  • The complaint asserts independent Claim 1 (Compl. ¶51).
  • Essential elements of Claim 1 (a system) include:
    • A time code generator for generating a time code signal synchronized with an input video stream.
    • An address generator that receives the time code signal and generates a corresponding address signal.
    • A database storing a plurality of indicators.
    • An encoder that receives the video stream and accesses a set of indicators from the database using the address signal, and encodes the video stream with that set of indicators.

U.S. Patent No. 7,028,327 - "Using The Electronic Program Guide To Synchronize Interactivity With Broadcast Programs," issued April 11, 2006

  • Technology Synopsis: The patent describes a method for synchronizing an interactive software application with a video program. It uses timing offsets, derived from an electronic program guide (EPG), to determine breaks in program content (e.g., commercial breaks) and to suspend and resume the interactive application accordingly (Compl. ¶¶ 71, 24).
  • Asserted Claims: At least Claim 13 is asserted (Compl. ¶72).
  • Accused Features: The "NFL Now" service is accused of infringing by using an EPG to provide a synchronized interactive experience, including managing interactivity during dynamic ad insertion breaks (Compl. ¶¶ 72, 25-27).

U.S. Patent No. 7,950,033 - "Utilization of Relational Metadata In A Television System," issued May 24, 2011

  • Technology Synopsis: This patent relates to using "relational metadata" to define relationships between different datasets, such as a video stream and related supplemental information. The system parses this metadata to trigger actions, such as presenting a highlight summary in a separate window (Compl. ¶¶ 91-92).
  • Asserted Claims: At least Claim 27 is asserted (Compl. ¶94).
  • Accused Features: The NFL Mobile and NFL Game Pass applications are accused of using relational metadata to present play highlights and related data to the user, for instance in a pop-up window when a "Big Play Marker" is selected (Compl. ¶¶ 94, 35).

U.S. Patent No. 7,055,169 - "Supporting Common Interactive Television Functionality Through Presentation Engine Syntax," issued May 30, 2006

  • Technology Synopsis: The patent describes a system for managing the presentation of digital media by first determining if prerequisite resources (e.g., sufficient bandwidth or CPU capacity for a high-definition stream) are available. The system prohibits the initiation of the presentation until the necessary resources are present (Compl. ¶¶ 114-115).
  • Asserted Claims: At least Claim 1 is asserted (Compl. ¶117).
  • Accused Features: Defendant's online streaming services, including NFL Game Pass, are accused of infringing by using manifest files that specify prerequisite directives (e.g., a required "bitrate") and determining a user's bandwidth and CPU capacity before initiating a high-definition stream (Compl. ¶¶ 117, 42).

U.S. Patent No. 7,020,888 - "System And Method For Providing An Omnimedia Package," issued March 28, 2006

  • Technology Synopsis: This patent addresses combining different types of data streams (e.g., audio, video, metadata) into a single, cohesive "omnimedia package" for broadcast. The system uses a "framework definition" to identify, format, and combine the disparate streams into a single broadcast stream (Compl. ¶¶ 137-138).
  • Asserted Claims: At least Claim 1 is asserted (Compl. ¶140).
  • Accused Features: The NFL Game Pass application is accused of generating "omnimedia content" by combining game video, audio, and metadata (such as game statistics and Big Play highlight markers) into a single stream for delivery to users (Compl. ¶¶ 140, 49).

U.S. Patent No. 6,233,736 - "Media Online Service Access System and Method," issued May 15, 2001

  • Technology Synopsis: The patent covers a method for allowing users viewing video content to directly access associated online information via an embedded link. The system extracts an address from the video signal and uses it to automatically establish a connection to an online information provider (Compl. ¶¶ 160-161).
  • Asserted Claims: At least Claim 8 is asserted (Compl. ¶163).
  • Accused Features: Defendant's streaming video services (NFL.com, NFL Now, etc.) are accused of infringing by providing VAST-compliant video advertising that includes click-through links, allowing users to directly access an advertiser's website (Compl. ¶¶ 163, 61-62).

U.S. Patent No. 6,154,172 - "System and Process for Limiting Distribution of Information on a Communication Network Based on Geographic Location," issued November 28, 2000

  • Technology Synopsis: This patent describes a system for controlling access to information based on the geographic location of the user. A server receives location information from a user's device, determines if that location is within a predefined restricted region, and limits access accordingly (Compl. ¶182; ’172 Patent, Abstract).
  • Asserted Claims: At least Claim 19 is asserted (Compl. ¶183).
  • Accused Features: The NFL GamePass and NFL Mobile platforms are accused of infringing by implementing geographic "black-outs." The system allegedly uses client IP address and routing information to determine a user's location and restrict access to certain game content based on predefined regions (Compl. ¶¶ 183, 68).

III. The Accused Instrumentality

Product Identification

  • The complaint names a suite of online video products and services, collectively referred to as the Infringing Instrumentalities for each respective patent (Compl. ¶¶ 23, 29, 51, 72, 94, 117, 140, 163, 183). These include:
    • Watch NFL Network/NFL Redzone applications
    • NFL Game Pass application
    • NFL Now online video delivery service
    • NFL Mobile application
    • NFL.com website
    • The NFL App
    • NFL Fantasy Football application

Functionality and Market Context

  • The accused instrumentalities are alleged to provide streaming interactive video content to users across numerous platforms, including mobile phones, tablets, personal computers, and streaming media devices (Compl. ¶¶ 16, 23).
  • Relevant functionalities described in the complaint include:
    • User Authentication: Requiring users to authenticate with a TV service provider to access protected content, a process that involves entering a PIN or password (Compl. ¶29). The complaint provides a screenshot of a login iFrame used for this purpose (Compl. p. 9).
    • Interactive Highlights: Providing "Big Play Markers" within the NFL Game Pass application that allow users to access metadata and highlights for specific plays in a game (Compl. ¶¶ 51, 17-19). The complaint includes a screenshot showing XML-encoded metadata associated with a play highlight (Compl. p. 18).
    • Content Synchronization: Using an electronic program guide in the NFL Now service to synchronize interactive content with the video stream, including suspending and resuming interactive controls during dynamic ad insertions (Compl. ¶¶ 72, 26-27). A screenshot shows an interactive slider bar for navigating content (Compl. p. 26).
    • Geographic Restrictions: Implementing "black-outs" for NFL GamePass and NFL Mobile that restrict access to game content based on the user's geographic location, as determined by their IP address or other data (Compl. ¶¶ 183, 68). The complaint includes a screenshot from an NFL help page explaining that game availability is "based on the location of your device" (Compl. p. 68).

IV. Analysis of Infringement Allegations

'861 Patent Infringement Allegations

Claim Element (from Independent Claim 9) Alleged Infringing Functionality Complaint Citation Patent Citation
an application which provides access to protected content, sending a request for a PIN to the user's device prior to granting access to the protected content The Watch NFL Network Application receives a request from a subscriber to access protected content and, in response, presents a request for user authentication. ¶29.B col. 4:20-24
information about the PIN code entering key-pressing operations by the user being supplied to the application and displayed in crypted form Information about key-presses for the PIN code is supplied to the application and displayed in an obfuscated form (e.g., as dots). A screenshot shows an obfuscated PIN entry field. ¶29.C; p. 10 col. 4:51-55
an authentication service manager for authenticating the subscribers such that the entered PIN code is not supplied to the application The accused system uses an "authentication service manager" to authenticate subscribers. This manager receives the PIN code, while the application itself does not. ¶29.C col. 4:25-30
once it is determined that the PIN code of the user matches the registered PIN code, giving authorisation to run the application After the PIN is verified, the system gives authorization to run the application, allowing the user to access the content. A screenshot shows the application after successful authentication. ¶29.D; p. 11 col. 4:62-65
  • Identified Points of Contention:
    • Scope Questions: A central question may be whether the accused "authentication service manager" constitutes the claimed "security manager." The analysis will likely focus on the degree of separation and independence between the application requesting authentication and the entity that actually receives and verifies the PIN.
    • Technical Questions: What evidence does the complaint provide that the PIN code is "not supplied to the application"? While the complaint alleges this (Compl. ¶29.C), the underlying architecture of the TV Everywhere service and the specific data flows between the NFL application and the third-party provider's authentication service will be a key factual issue.

'729 Patent Infringement Allegations

Claim Element (from Independent Claim 1) Alleged Infringing Functionality Complaint Citation Patent Citation
a time code generator for generating a time code signal that is synchronized with an input video stream The accused NFL Game Pass application comprises time code signals to synchronize play highlights ("Big Play Markers") with the NFL video stream content. ¶51.A-C col. 4:2-5
an address generator for receiving said time code signal and for generating a corresponding address signal The system allegedly decodes the time code signals and uses them to generate corresponding address signals that index a database of metadata for play highlights. ¶51.B col. 4:5-8
a database storing a plurality of indicators A database of metadata for play highlights is maintained by or on behalf of NFLE, which is correlated to "Big Play" indicators. A screenshot shows XML metadata for a play highlight. ¶51.B; p. 18 col. 4:9-10
an encoder for... accessing a set of indicators that are stored in said database using said address signal as an address into said database and for encoding said video stream with said set of indicators The address signals are used to index the play highlights database, allowing a set of indicators for the "Big Play" feature to be encoded in the video stream. ¶51.C col. 4:11-16
  • Identified Points of Contention:
    • Scope Questions: Does the accused system's method of associating metadata with video content meet the specific structural limitations of an "address generator" that translates a "time code signal" into a database "address signal"? The court may need to construe the scope and meaning of these distinct functional components.
    • Technical Questions: The complaint alleges a specific data flow consistent with the claim. However, the provided XML screenshot (Compl. p. 18) shows metadata containing time information (e.g., ClockTime="10:44") but does not, on its face, prove the existence of the claimed time code generator -> address generator -> database architecture. The actual implementation of the "Big Play Markers" feature will be a central factual dispute.

V. Key Claim Terms for Construction

For the ’861 Patent

  • The Term: "security manager"
  • Context and Importance: This term is the central component of the claimed invention, responsible for handling the secret PIN separately from the application. The infringement analysis will depend on whether the accused "authentication service manager" (Compl. ¶29.C), which may be part of a third-party service provider's system, falls within the scope of this term.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The specification describes the security manager functionally as a means for "comparing the PIN code of the user... with a registered PIN code, and giving authorisation" (’861 Patent, col. 2:21-24). This functional language may support a construction that is not limited to a specific hardware or software implementation.
    • Evidence for a Narrower Interpretation: The detailed description notes that the security manager "comprises a small computer system including a central processing unit (CPU), memory and local storage" (’861 Patent, col. 3:23-26). This language could support a narrower construction requiring a distinct, self-contained processing entity.

For the ’729 Patent

  • The Term: "address generator"
  • Context and Importance: This term describes the nexus between the time code and the database. The dispute will likely focus on whether the accused system has a distinct component that performs the claimed function of "generating a corresponding address signal" from a time code, or if it uses a different method to link time-based events to metadata.
  • Intrinsic Evidence for Interpretation:
    • Evidence for a Broader Interpretation: The patent describes the function as decoding the time code signal and generating a corresponding address signal (Compl. ¶49). This functional description could be read broadly to cover any software module that converts a time value into a key for a database lookup.
    • Evidence for a Narrower Interpretation: Figure 3 of the patent depicts the "ADDRESS GENERATOR" (314) as a distinct structural block separate from the "TIME CODE GENERATOR" (310) and the "DATABASE" (318) (’729 Patent, Fig. 3). This depiction may support an argument that the term requires a structurally separate component, not merely a software function integrated within another component.

VI. Other Allegations

  • Indirect Infringement: For each asserted patent, the complaint alleges both induced and contributory infringement. Inducement is based on allegations that NFLE encourages and instructs its users to install and operate the accused applications in an infringing manner through its websites and technical assistance (e.g., Compl. ¶¶ 35, 58, 78). Contributory infringement is based on allegations that the specific infringing functionalities are "especially made and adapted" for infringement and are not staple articles of commerce with substantial non-infringing uses (e.g., Compl. ¶¶ 38, 40, 63, 83).
  • Willful Infringement: The complaint alleges that NFLE's infringement has been willful for all asserted patents. This allegation is based on pre-suit notice letters sent to NFLE counsel, with the earliest notice dated November 30, 2015 (Compl. ¶2). The complaint further alleges that NFLE, having been aware of the patents, "opted to make the business decision to 'efficiently infringe'" rather than take a license (e.g., Compl. ¶¶ 42, 65, 85).

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

  • A core issue will be one of architectural correspondence: Do the accused NFL streaming services, which integrate features from various internal and third-party systems, actually implement the specific, multi-component architectures required by the patents (e.g., the distinct "security manager" of the ’861 patent or the "time code generator -> address generator -> database" chain of the ’729 patent), or is there a fundamental mismatch in technical operation?
  • A key evidentiary and legal question will be one of willfulness and the scope of damages: Given the allegations of pre-suit notice dating back to 2015 and a prior, dismissed lawsuit, what was the extent of NFLE's knowledge of the patents, and how will the history of interactions between the parties influence the potential for enhanced damages and the start date for any damages calculation?
  • A central question of claim construction will likely be whether functional claim language describing system components (e.g., "address generator," "security manager") should be interpreted broadly to cover any software that performs the recited function, or more narrowly to require distinct structural modules as depicted in the patent figures.
